    Coking and semi hard coking coal price agreements had been reached, but, strangely enough, the reaching of common ground on semi soft coking coal, ultra low volatile coal and thermal coal seemed some way off. More of this phenomenon later, but suffice to say that, traditionally, the semi soft and thermal coal prices have fallen into place as soon as the hard, or prime, coking coal prices have been determined. The rise and rise of the popularity of the ultra low volatile coals has seen demand for this type of coal grow almost exponentially. Perhaps one of the most interesting facets of the coking coal settlements announced to date is that the deals appear almost to have been preordained. The extraordinary thing is that the preordination has been at the prescience of the sellers. Traditionally, coking coal price fixing has been the prerogative of the Japanese Steel Mills (JSM) cartel (Nippon, NKK, Kawasaki, Kobe and Sumitomo) who presented a united front to a somewhat disorganised force of predominantly Australian and Canadian sellers. However, by the time JFY 2001 had come round, the rules of the game had changed

  2. 1988 coal price negotiation

    1988-12-01

    In the negotiation on raw coal price for 1988, which began at the end of 1987, Australia requested price rise of 4 - 5 dollars for the reason of rise of Australian dollars, conditions of mines, price drop in the past five years, and world supply/demand of coal. Japan insisted to maintain the price of preceding year. The talk ended in a dead lock which could last a long time. Negotiation on the Canadian coal price also encountered difficulties but an agreement was obtained in March as Japan accepted the increased price. After which, Japan and Australia agreed to raise the price by 2.90 dollars and an increase over last year. Producing countries also requested a wide price rise as 7.50 dollars for general coal, making in this area very difficult to progress. Finally, they agreed to raise the price by 6.30 dollars and the electric power utility in Japan responded by importing of U.S. coal, which has a lower heat output but is also cheaper. It depends on Australia for 70% of coal supply but started to diversify the source. 3 tabs.

    Examination of panel data on listed coal companies on the Australian exchange over January 1999 to February 2010 suggests that market return, interest rate premium, foreign exchange rate risk, and coal price returns are statistically significant in determining the excess return on coal companies’ stock. Coal price return and oil price return increases have statistically significant positive effects on coal company stock returns. A one per cent rise in coal price raises coal company returns ...

    This report examines the following: current US coal exports; the domestic steam coal market and the domestic coking coal market; transport of export coal; reserves, production and productivity; and export markets for US coal. The report concluded that from the mid-1990s, buyers of the leading US coal export brands will face steadily rising prices as a result of fundamental shifts in the US domestic market affecting those regions supplying the bulk of the country's exports. The coals at the forefront of these price rises will be low-sulphur steam coal and high-volatile coking coal. Districts 8 and 7, the region that produces most of these types of coal, will be called upon to expand production by 50 m short tons per year by the end of the decade. However, there will be little scope for further productivity gains and because of this, and the need for significant capital investment, mining costs will rise. Inland freight rates will also rise as barge companies and railroads seek to cover investments. 53 figs., 66 tabs.

    In recent years, coal price has risen rapidly, which has also brought a sharp increase in the expenditures of thermal power plants in China. Meantime, the power production price and power retail price have not been adjusted accordingly and a large number of thermal power plants have incurred losses. The power industry is a key industry in the national economy. As such, a thorough analysis and evaluation of the economic influence of the electricity price should be conducted before electricity price adjustment is carried out. This paper analyses the influence of coal price adjustment on the electric power industry, and the influence of electricity price adjustment on the macroeconomy in China based on computable general equilibrium models. The conclusions are as follows: (1) a coal price increase causes a rise in the cost of the electric power industry, but the influence gradually descends with increase in coal price; and (2) an electricity price increase has an adverse influence on the total output, Gross Domestic Product (GDP), and the Consumer Price Index (CPI). Electricity price increases have a contractionary effect on economic development and, consequently, electricity price policy making must consequently consider all factors to minimize their adverse influence.

  6. The asymmetric effect of coal price on the China's macro economy using NARDL model

    The present work endeavors to explore the asymmetric effect of coal price on the China's macro economy by applying nonlinear autoregressive distributed lag (NARDL) model for the period of January 2005 to June 2015. The obtained results indicate that the coal price has a strong asymmetric effect on China's macro economy in the long-run. Namely one percent increase in coal price leads to 0.6194 percent of the China's macro economy increase; and while the coal price is reduces by 1 percent, the China's macro economy will decrease by 0.008 percent. These data indicate that when coal price rises, the effect on China's macro economy is far greater than the price decline. In the short-run, coal price fluctuation has a positive effect on the China's macro economy.

  7. Analysis of thermal coal pricing and the coal price distortion in China from the perspective of market forces

    The price of thermal coal has always been the focus of the debate between coal mining industry and electric power industry. The thermal coal price is always lower than other same quality coal, and this phenomenon of thermal coal price distortion has been existing in China for a long time. The distortion coal price can not reflect the external cost and the resource scarcity of coal, which could result in environment deteriorating and inefficient resource allocation. This paper studied the phenomenon of thermal coal price distortion through economic theoretical modeling and empirical cointegration analysis from the perspective of market forces. The results show that thermal coal price is determined by electricity price, the prediction elasticity of a electricity enterprise, price elasticity of demand of electricity, the input prediction elasticity of a electricity enterprise and the price elasticity of supply of thermal coal. The main reason of coal price distortion is the unbalance market force of coal industry and thermal coal generation industry. The distortion rate of coal price is positively related to the market force of electric power industry and negatively related to the industrial concentration of coal industry. - Highlights: • This paper studied thermal coal pricing and the coal price distortion in China. • The main reason of coal price distortion is the unbalance market force. • Thermal coal price is also influenced by electricity price and price elasticity of demand of electricity. • The distortion rate of coal price is negatively related to the industrial concentration of coal industry.

    The coal world experienced a true upheaval in the past five years World coal consumption went up 28 % between 2000 and 2005, as a result of the strong growth in Chinese demand. The growth should continue in the coming years: electrical plant builders' orders are mainly for coal. The regained interest in coal is based on the constraints experienced by competing energies (increase in oil and natural gas prices, geopolitical uncertainties, supply difficulties) and by the abundant reserves of coal in the world and the competitiveness of its price. The strong growth in world coal demand comes with a change in rules governing steam coal trading. While long term bilateral agreements were most common until the late nineties, there has been a true revolution in coal marketing since 2000: spot contracts, stock exchange emergence and futures contracts, price indexes. In a few years, the steam coal market has become a true commodities market, overtaking many more goods. The price of coal has also gone through strong variations since 2003. Whereas the price had been stable for decades, in 2004 the strong increase in China' s demand for coal and iron ore resulting in transport shortage, caused a strong increase in CAF coal prices. Since then, prices have gone down, but remain higher than the Eighties and Nineties levels. In spite of the increase, coal remains available at more competitive prices than its competing energies.

    1987-12-01

    Price and amount of coking coal for the fiscal year 1987 was announced. Contracted coals were 5 types with Australia and 4 types with Canada by end Jan, 1987. Average price came down from 47.72 US dollar/t to 43.57, i.e., 4.15 US dollar/t price decline to the previous year. In addition, the number of the branded coal are negotiated with Australia is 23 cases, 5 brands with Canada, 1 with South Australia, 2 with USSR, and 3 with China. General trend of the price is as follows: Coking coal price is influenced by the decrease of the Japanese steel production as well as the world-wide surplus of coal, and all import prices have gone down except semi-caking coal of USA. Price level is very high in USA and Canada, but is low in Australia and others. Recently, strikes are frequent in South Africa and Canada; profit of coal mines is coming down; US dollar rate is sinking; contract quantity is shrinking; these give an estimate that both general coal and coking coal prices will not so easily go down further.

    The Clean Air Act Amendments will create some important changes in the US domestic steam coal market, including price increases for compliance coal by the year 2000 and price decreases for high-sulfur coal. In the international market, there is likely to be a continuing oversupply which will put a damper on price increases. The paper examines several forecasts for domestic and international coal prices and notes a range of predictions for future oil prices

  11. Fuel prices, emission standards, and generation costs for coal vs natural gas power plants.

    2013-05-07

    Low natural gas prices and stricter, federal emission regulations are promoting a shift away from coal power plants and toward natural gas plants as the lowest-cost means of generating electricity in the United States. By estimating the cost of electricity generation (COE) for 304 coal and 358 natural gas plants, we show that the economic viability of 9% of current coal capacity is challenged by low natural gas prices, while another 56% would be challenged by the stricter emission regulations. Under the current regulations, coal plants would again become the dominant least-cost generation option should the ratio of average natural gas to coal prices (NG2CP) rise to 1.8 (it was 1.42 in February 2012). If the more stringent emission standards are enforced, however, natural gas plants would remain cost competitive with a majority of coal plants for NG2CPs up to 4.3.

    Full Text Available Coal plays an important role in China’s energy structure and its price has been continuously decreasing since the second half of 2012. Constant low price of coal affected the profits of coal enterprises and the coal use of its downstream firms; the precision of coal price provides a reference for these enterprises making their management strategy. Based on the historical data of coal price and related factors such as port stocks, sales volume, futures prices, Producer Price Index (PPI, and crude oil price rate from November 2013 to June 2016, this study aims to forecast coal price using vector autoregression (VAR model and portray the dynamic correlations between coal price and variables by the impulse response function and variance decomposition. Comparing predicted and actual values, the root mean square error (RMSE was small which indicated good precision of this model. Thus this short period prediction can help these enterprises make the right business decisions.

    The challenge for the gas industry is to become price competitive with coal-fired electricity if it wants a larger share of the energy market. Returning to the issue of greater use of gas for electricity generation, the author points out that although electricity prices were rising they were still below the point where gas-fired electricity generation was viable.

    1989-06-01

    The Institute of Energy Economics summarized the negotiated prices for coals to be loaded in 1989 for coke making coal and non coking coal. In order to suppress the price increase of coke making coal as low as possible, five iron making companies where Nippon Steel and Kawasaki Steel are the center, started to negotiate from US showing lower markup requirement and decided to increase the price from $1.65 to $2. They agreed to increase the price for Australian coal as follows: $3.5 for coke making coal, $5.5 for slightly coking coal, $4.5 for weakly coking coal and further they contracted with $3.5 markup and $3.5 markup for China and USSR coals from December, 1988 to March, 1989. The negotiation for non coking coal started from USSR similarly and agreed with $3 markup for USSR coal, $5.3 markup for South African coal, and $3.5 markup for Australian coal but the negotiation is performing to China coal on Australian basis. The Australian share for non coking coal is higher, that is, 70% and therefore Japanese power generating companies are promoting to import non coking coal from US for the competition. 5 tabs.

    The revival of coal prices is providing record profits for Australian coal producers. As the world's largest coal exporter, any move in coal prices has significant ramifications for the Australian economy. The coal boom of the mid-1980s resulted in a massive increase in mine capacity and subsequently excess supply. This resulted in the decade between 1990 and 2000 seeing benchmark prices for coking coal in Japan plummeting to $US 39 a tonne (down from around the $US 52 mark) and a price of $US 28 for a tonne of steaming coal. Asia's financial problems, late in the decade coupled with a rapid fall in Asian steel making, also added to our coal export woes. As a result for most of the 1990s, Australia's coal sector delivered inadequate returns, was seen as over-capitalised and suffered from a profound investor indifference. But the sector is now seeing a definite turnaround in fortunes. Prices for thermal coal are on the rise and the benchmark coking coal prices to Asia have also jumped. Market analysts reported the price for contract deliveries of thermal coal in April this year were $US 34.50 ($AUD 69.35) up by $US 5.75 from the same time last year. The increased production is expected on the back of a continued rise in export demand, further improvement in prices, significant improvements in mine productivity, a weak Australian dollar and the probability of new projects and mine extensions going into operation. The improved returns have also flowed into rising valuations for listed coal miners. Over the last year, coal miners such as MIM and Gympie Gold, have delighted in share price gains of 12 per cent and 55 per cent respectively. These sort of performances are being repeated across the Australian industry

    Since China decontrolled coal prices, its coal price has risen steadily and been unusually volatile. In 2011 in particular, high coal prices and capped electricity prices in China discouraged coal-fired power generation, triggering widespread power shortages. We suggest that these coal-price disturbances could be symptomatic of a major change in pricing dynamics of global fossil-fuel markets, with increasing correspondence between coal and oil prices globally. Historically, global coal prices have been more stable and lower than oil and natural gas prices on a per-heat basis. In recent years, however, coal prices have been increasingly volatile worldwide and have tracked other fossil fuel prices more closely. Meanwhile, the recent development of unconventional gas has substantially decoupled US natural gas and oil prices. Technically, low US natural gas prices, with potential fuel switching, could drive US domestic coal prices lower. However, this effect is unlikely to counteract the overall trend in increasing coal consumption globally. China's market size and unique, partially-controlled energy system make its reform agenda a key force in the global economy. Policymakers in the US, E.U. and elsewhere should monitor China's economic reform agenda to anticipate and respond to changes accompanying China's increasing importance in the global energy economy. - Highlights: ► Since China decontrolled its coal prices, the price of coal has risen steadily in China, accompanied by unusual volatility. ► Relatively high and volatile coal prices have triggered widespread power shortages in China. ► Coal and oil prices have already become, and continue to become, more closely linked globally. ► China's demand will likely drive up global coal prices and make them as volatile as that of other fossil fuels. ► Policymakers should monitor China's economic reform agenda to anticipate and respond to changes in the global energy economy.

    Researchers of Peak oil warn about imminent worldwide coal shortages as of 2025. Countries that fully depend on coal import, such as the Netherlands, run great risks due to strongly rising prices and insecurity of supply. How large is the supply of extractable coal? How long will extraction and export continue undisturbed under increasing demand? What effect will this have on the coal price? The real data on supply, demand, price and export mainly tell a tale of unreliable reserves and high prices according to Greenpeace. [mk] [nl

  19. The 1988 coal outlook: steadily rising consumption

    Total coal use - domestic and foreign - will reach 910 million tons in 1988, an expansion of 1.3% from an estimated 898 million tons in 1987. The overall rise in consumption will add to inventory needs. Moreover, lower interest rates cut effective carrying costs and further encourage the holding of coal stocks by users. The results will be a gain in inventories of 3.5 tons by the end of 1988. As a result of all these factors, coal production is anticipated to rise by 11.6 million tons, or 1.2%, which projects firm markets in a time of relatively soft economic conditions in the USA. 2 tabs.

    Highlights: • We showed that brown coal is the substitute for black coal only at the time of the investment decision. • We compiled the model used in a calculation of the economically justified price for the productive and extractive component. • The resulting economically justified price is on a par with the current black coal price. • The proposed methodological approach is applicable to solve similar tasks not only in the energy sector. - Abstract: Brown coal is one of the dominant local strategic raw materials in Europe, used, to a large extent, in the power-generating industry. The current situation, where the price of gas and electricity precludes the efficient use of gas sources, leads to the extraction of older sources, chiefly brown coal ones. In tandem with a turning away from nuclear power, brown coal is experiencing a renaissance and the issue of brown coal price setting is, and will be, relevant. This paper deals with a proposal of a new method for determining the base price, consisting of defining the reference fuel chain for electricity and heat production based on brown coal. It builds on the notion that the degree of risk of the involved parties should be reflected in the modified amount of revenue per capital invested. The resulting price is then an economically justified price which encourages a respect for the specific features of the market in question and set the base price of the commodity in a way that is acceptable for both the extractive and the productive components of the fuel chain

  1. Research on Double Price Regulations and Peak Shaving Reserve Mechanism in Coal-Electricity Supply Chain

    2013-01-01

    Full Text Available The game models were used to study the mechanism of coal-electricity price conflict under conditions of double price regulations of coal and electricity. Based on this, the peak shaving reserve mechanism was designed to probe into the countermeasures against the coal-electricity price conflicts. The study revealed that in the boom seasons of coal demand, the initiatives of the coal enterprises to supply thermal coal and the electricity enterprises to order thermal coal are reduced under conditions of double price regulations. However, under the circumstances of coal price marketization, in the boom seasons of coal demand the thermal coal price may go up obviously, the initiatives of the coal enterprises to supply thermal coal are increased, and meanwhile the initiatives of the power enterprises to order thermal coal are decreased dramatically. The transportation capacity constraint of coal supply leads to the evident decrease of the initiatives of coal enterprises for the thermal coal supply. The mechanism of peak shaving reserve of thermal coal may not only reduce the price of coal market but also increase the enthusiasm of the power enterprises to order more thermal coal and the initiatives of the coal enterprises to supply more thermal coal.

    2016-09-01

    Full Text Available The steam coal price in China has been continuously decreasing since the second half of 2012. Constant low price of coal will accelerate the development of thermal power, cause more serious air pollution problems, and bring adverse influence to China’s energy reformation in the future. Therefore, analyzing the factors underlying the phenomenon of the decreasing steam coal price is significant. In this study, we first qualitatively analyze five main factors, namely, economy, supply, demand, substitutes, and port stocks. On the basis of the relationships among these five factors, we obtain the causality diagram and the system flow diagram of coal price for further quantitative research. Then, we conduct an empirical analysis using the system dynamics (SD method and determine the simulated price from 2012 to 2017. Finally, we discuss the running results and come to the conclusion that the steam coal price will continue to decrease under the combined actions of the five main factors and it will not rebound in the near future.

    2016-01-01

    A dynamic partial equilibrium model, TIMES (​The Integrated MARKAL-EFOM System), is built to optimize the energy system in a post-transition European country, the Czech Republic. The impacts of overall nine scenarios on installed capacity, capital and fuel costs, air quality pollutant emission, emission of CO_2 and environmental and health damage are quantified for a period up to 2050. These scenarios are built around three different price sets of the EUA (EU allowance) to emit greenhouse gasses alongside a policy that retains the ban on brown coal mining in two Czech mines, a policy that will allow the re-opening of mining areas under this ban (i.e. within the territorial ecological limits), and a low natural gas price assumption. We found that the use of up until now dominant brown coal will be significantly reduced in each scenario, although reopening the coal mines will result in its smaller decline. With low EUA price, hard coal will become the dominant fuel in electricity generation, while nuclear will overtake this position with a 51% or even 65% share assuming the central price of EUA, or high EUA price, respectively. The low price of natural gas will result in an increasing gas share from an almost zero share recently up to about 42%. This stimulus does not however appear at all with low EUA price. Neither of these scenarios will achieve the renewable energy sources 2030 targets and only a high EUA price will lead to almost full de-carbonization of the Czech power system, with fossil fuels representing only 16% of the energy mix. The low EUA price will result in an increase in CO_2 emissions, whereas the high EUA price will reduce CO_2 emission by at least 81% compared to the 2015 reference level. Those scenarios that will result in CO_2 emission reduction will also generate ancillary benefits due to reduction in air quality emissions, on average over the entire period, at least at 38€ per t of avoided CO_2, whereas scenarios that will lead to CO_2

    Coal-fired plants are the most polluting way to produce electricity due to their high CO2 emissions. But are they a good choice from an economic point of view? According to Greenpeace the answer is no: the price of coal is rising, construction costs are increasing and CO2 emissions will be priced. Nevertheless, E.On is developing plans for a new coal-fired plant at the Maasvlakte with the support of the Dutch government. [mk] [nl

A minimal significance of price factors has been revealed in the process of the market analysis. This suggests that a lower price does not guarantee an increase in consumer demand. Thus, factors of non-price competition are of great importance in the market in question. The expert survey has identified the factors of non-price competition which influence consumer perceptions. A perceptual map has been constructed on the basis of the identified factors by means of the factor analysis to determine the positioning of each high-rise building relative to the consumer requirements. None of the high-rise residential buildings in the market in question meets the consumers’ expectations of an “ideal facility”.

A minimal significance of price factors has been revealed in the process of the market analysis. This suggests that a lower price does not guarantee an increase in consumer demand. Thus, factors of non-price competition are of great importance in the market in question. The expert survey has identified the factors of non-price competition which influence consumer perceptions. A perceptual map has been constructed on the basis of the identified factors by means of the factor analysis to determine the positioning of each high-rise building relative to the consumer requirements. None of the high-rise residential buildings in the market in question meets the consumers' expectations of an "ideal facility".

    Coal and gas continue to play a significant role in the European power generation system, especially in Germany. According to the AG energy balances, the share of hard coal in German gross electricity generation in 2016 was 17.2% and natural gas 12.4%. In addition to the CO 2 price, the prices for steam coal and natural gas are a key factor in determining which gas or coal power station is in Merit Order and whether it comes to a fuel switch. Declining gas prices have been rising sharply since the middle of 2016, and the volatile prices for steam coal have been rising. This article discusses the developments and factors responsible for these developments, which could be expected in the near future, and the implications for the gas-coal spread in the electricity market.

    Full Text Available The coal consumption of China reached 2.75 billion tons of standard coal in 2013, which accounted for 67.5% of total energy consumption and more than 50% of global coal consumption. Therefore, the impact of coal price is huge on coal market and even energy market in China. As a large consumer of coal, thermal power enterprise has a strong sensitivity to coal price. In order to balance the rising cost of enterprises due to coal price, we need to analyze the interests of multiple stakeholders. Firstly, this paper combined the Nash equilibrium and cobweb model and proposed the characteristics in different cobweb model. Then, for coal, power, and energy companies, the dynamic game analysis model is constructed. This model gives a game analysis in four scenarios and quantifies the decision of each stakeholder in different coal prices. Finally, the impact figure of different coal prices on each stakeholder has been drawn. The impacts of different coal or thermal power prices on different markets have been put forward, so relevant policy recommendations have been proposed combined with the cobweb model.

    The new system is self-complete through grading to pricing. It grades non-coking coal by moisture and ash contents. Coking coal is graded by GKLT coke type and ash content. Volatile matter content is used as a supporting indexer, where necessary. Through the grade data, a coal is evaluated into a single numeral which depicts the coaly matter content and its nature or effectiveness. This value, called effective coaly matter, is converted to a relative rupee value or price index/price. Pragmatics and versatility of the system are discussed.

    Apollo Gas, a Toronto-based gas marketer, is considering options to enhance unit holder value, including sale of its 21,000 gas supply contracts, just weeks after it was forced out of the Alberta market by rising gas prices. Although the company had reported first quarter revenues of more than $15 million and earnings through that period of about $2.1 million, increases of 33 per cent and 38 per cent respectively over the same period in 1999, the company is resigned to the fact that such performance markers are not likely to be reached again in the foreseeable future, hence the decision to sell. About 95 per cent of Apollo's current transportation service volumes are matched to existing fixed-price supply contract which are due to expire in November 2000. After that, it is about 75 per cent matched for the balance of the term of its customer contracts (mostly five years). This means that the company is exposed to market prices that are likely to continue to increase. If this prediction holds true, Apollo would be forced to purchase the unhedged volumes of gas it needs to service its customers in the spot market at prices higher than prices the company is charging to its customers.

    The last decade has been a sad one for coal exporters with only two price increases going the sellers' way, one in 1995 and the other in 1996. True, the financial hardships imposed upon the miners have resulted in improvements in all aspects of the coal chain. Mine productivity as measured in tonnes of output per employee is up, while rail and port charges and even, albeit at more modest levels, government charges, are down. However there is a widespread viewpoint that this will be the year of the price rise and, potentially, a big one. The difference in the forthcoming coal negotiations with the Japanese buyers is that, this time, the tightness of the market, both in coking and thermal coal, is demand driven

    Increases in tobacco taxation can lead to reductions in tobacco consumption and prevalence of use across social groups. However, use of price-minimisation strategies to manage current and future tobacco use and the role of financial stress is less understood. This study aimed to measure the effect of cigarette price increases on price-minimisation strategy endorsement and financial stress among socioeconomically disadvantaged smokers. Community service organisation welfare recipients in NSW, Australia completed a touchscreen survey. Smoking history, financial stress, highest price to quit and responses to hypothetical cigarette price increases were assessed. Participants were 354 smokers (response rate = 79%). Most participants received income from a government pension (95%), earned price rises, significantly more participants endorsed trying to quit in response to the larger increase scenario (P price-minimisation strategies (e.g. switching to cheaper brands/products) were endorsed, but remained constant across hypothetical scenarios; level of financial stress appeared to have little influence. Smokers indicating they would not change their smoking in response to price rises had higher levels of nicotine dependence. Socially disadvantaged smokers endorsed numerous price-minimising strategies to maintain smoking at hypothetically increased costs. Larger cigarette price rises motivated more smokers to consider quitting, while price-resistant smokers appeared to have a more entrenched smoker status. © 2013 Australasian Professional Society on Alcohol and other Drugs.

    1987-01-01

    The future international price of coal is a central issue in the economic comparison of coal-fired and nuclear power stations. However, this is very difficult to estimate as prices are uncertain and subject to wide margins of error. Recent trends are discussed. The increase in the seaborne steam coal trade is one trend. Although only about 5% of steam coal is traded, this is mainly in the Far East and in Western Europe. It is steam coal prices which are relevant in considering nuclear economies. The structure of the international steam coal market is explained. An assessment of future prices of steam coal considers both demand and supply. The delivered cost of steam coal to N.W. Europe in 1986 is shown - the main suppliers being Australia, Colombia, South Africa and the USA. China and Poland are also exporters of steam coal. Currently, there is an over-supply which is keeping the price low. However, as demand increases prices are likely to rise in the 1990s but with upper limits depending on the total volume of trade. Thirteen graphs or maps illustrate the figures on which the discussion and conclusions are based. (UK)

  6. Global Coal Trade. From Tightness to Oversupply

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2013-01-01

    Over the past four years, international coal trade has been reshaped by China's surging imports. China, which was still a net exporter in 2008, became the world's first coal importer in 2011, taking over the position that Japan has occupied for three decades. Its imports have continued their rising trend and reached a record level in 2012, despite the country's economic slowdown. China imported 289 million tons of coal in 2012, up 30% over 2011. It now accounts for 23% of global imports. Although China is the world's largest coal producer, several factors have contributed to the sudden rise in its imports, including the higher cost of domestic coal relative to international prices and bottlenecks in transporting domestic coal to south-eastern provinces. More recently, another event shook the international coal business: the United States have been back on the market. The collapse of U.S. gas prices, to $4/million Btu in 2011 and even $2.75/million Btu in 2012, linked with the 'shale gas revolution', has made coal uncompetitive in the electricity sector, its main outlet on the U.S. market. U.S. coal demand dropped 4% in 2011 and 11% in 2012. The reduction in domestic demand has forced U.S. miners to look for overseas outlets. Their exports surged by 31% in 2011 and 16% in 2012. They reached 112 million tons in 2012, more than twice the level of 2009. The United States, which almost disappeared from the international steam coal market in the 2000's, have regained a larger share of the total coal export market, 9% in 2012, against 6% in 2009. These developments, although not directly linked, have a huge impact on the global market and pricing of coal. Chinese imports have helped the market to quickly recover from its low level of 2008-2009. The speed and magnitude of China's coal imports even shifts the market from a sluggish to a tight situation. Prices started to rise after their collapse in the second half of 2008 caused by the economic and financial crisis

    This article discussed conditions in world coking coal markets. There is increased demand from Asia for metallurgical coal imports. World iron production was up 22 percent in first 7 months of 2010. Supply is up in Australia, the United States, Canada, New Zealand, Russia, and Mongolia, but the unexpected surge in supply caused prices to drop following a robust start to the year. Coking coal exports are up for the United States and Australia, but a delay in expanded production is expected until 2014. There is increased demand from Brazil, India, Taiwan, South Korea, and Japan as well as new plants in Thailand, Indonesia, and Brazil. Unexpectedly, Australia is backing out of the Chinese market but increasing exports to Japan and South Korea. India is seeing flat performance in iron production and imports, and the United States has surged back into Asia. A considerable increase is expected in the seaborne import requirement by 2020. Prices are expected to fall and then rise. This presentation also discussed whether coking coal index pricing is impossible or inevitable. 3 tabs., 5 figs.

In his talk, the prime minister explains the reasons of the crisis (increase of worldwide consumption, political tensions in the Middle East..) and presents the strategy and main trends of the French energy policy: re-launching of energy investments in petroleum refining capacities and in the nuclear domain (new generation of power plants), development of renewable energy sources and in particular biofuels, re-launching of the energy saving policy thanks to financial incentives and to the development of clean vehicles and mass transportation systems. In a second part, the prime minister presents his policy of retro-cession of petroleum tax profits to low income workers, and of charge abatement to professionals having an occupation strongly penalized by the rise of oil prices (truckers, farmers, fishermen, taxi drivers).

    A shortage of bituminous coal is now being witnessed on the world market, which stems from an increase in demand for it. The prices for bituminous coal, which have been increasing since 1988, will continue to rise in 1990. World coal production in 1989/1990 has been estimated by the Australian Bureau of Mineral Resources at 3,370 million tons, which is 50 million tons more than in the preceding year. Australian experts predict a doubling in world demand for coal by 2025. Many Australian coal mining companies, counting on the increased demand in the future, are taking measures to consolidate production and strengthen their financial base in order to accelerate development of new fields or expand production at existing mines. It is expected that the highest rates of growth in demand will be for power coal. Because of increased world production of steel the demand for coking coal will also rise, but the rates of growth will be much lower than for power coal

    Price negotiation on metallurgical coal imported by Japan in fiscal 1994, which started in December 1993, came to a conclusion at once over nearly all brands of both countries of Australia and Canada, taking a conclusion of three brands of Canada on 24th of January as a turning point. The width of reduction in price was 3.85$ (7.81%) at heavy caking coal, 3.50$ (8.00%) at semi-caking coal, and 3.30$ (8.30%) at combined non- and slight caking coal. Reduction in steel production in Japan and abundance in coal production in the world produced this result. The conclusions mentioned above were followed by conclusions in negotiation on metallurgical coal of South Africa and China. Concerning steam coal, negotiation on an export/import treaty between China and Japan was concluded on 29th of March as the head of a series of steam coal shipped in fiscal 1994. The quantity was increased by 800 kton than in fiscal 1993, the price was reduced by 3.30$ or 3.20$ (9.2% or 9.4%). Negotiations on steam coal of Australia, Indonesia, and the Western U.S. were concluded after hard negotiations, although negotiation is being continued for South Africa steam coal. 1 fig., 7 tabs.

  12. Gas and coal competition in the EU Power Sector

    International Nuclear Information System (INIS)

    2014-06-01

    Despite its many assets, a confluence of factors - including flat electricity demand, rising use of renewable energy sources, falling wholesale electricity market prices, high gas prices relative to coal and low CO 2 prices - has eroded the competitiveness of natural gas in the EU power sector. The share of natural gas in the EU electricity mix has decreased from 23% in 2010 to 20.5% in 2012. By contrast, coal-fired power stations have been operating at high loads, increasing coal demand by the sector. This thorough analysis by CEDIGAZ of gas, coal and CO 2 dynamics in the context of rising renewables is indispensable to understand what is at stake in the EU power sector and how it will affect future European gas demand. Main findings of the report: - Coal is likely to retain its cost advantage into the coming decade: The relationship between coal, gas and CO 2 prices is a key determinant of the competition between gas and coal in the power sector and will remain the main driver of fuel switching. A supply glut on the international coal market (partly because of an inflow of US coal displaced by shale gas) has led to a sharp decline in coal prices while gas prices, still linked to oil prices to a significant degree, have increased by 42% since 2010. At the same time, CO 2 prices have collapsed, reinforcing coal competitiveness. Our analysis of future trends in coal, gas and CO 2 prices suggests that coal competitive advantage may well persist into the coming decade. - But coal renaissance may still be short-lived: Regulations on emissions of local pollutants, i.e. the Large Plant Combustion Directive (LCPD) and the Industrial Emissions Directive (IED) that will succeed it in 2016, will lead to the retirement of old, inefficient coal-fired power plants. Moreover, the rapid development of renewables, which so far had only impacted gas-fired power plants is starting to take its toll on hard coal plants' profitability. This trend is reinforced by regulation at EU or

    The features of the asynchronous correlation between accident indices and the factors that influence accidents can provide an effective reference for warnings of coal mining accidents. However, what are the features of this correlation? To answer this question, data from the China coal price index and the number of deaths from coal mining accidents were selected as the sample data. The fluctuation modes of the asynchronous correlation between the two data sets were defined according to the asynchronous correlation coefficients, symbolization, and sliding windows. We then built several directed and weighted network models, within which the fluctuation modes and the transformations between modes were represented by nodes and edges. Then, the features of the asynchronous correlation between these two variables could be studied from a perspective of network topology. We found that the correlation between the price index and the accidental deaths was asynchronous and fluctuating. Certain aspects, such as the key fluctuation modes, the subgroups characteristics, the transmission medium, the periodicity and transmission path length in the network, were analyzed by using complex network theory, analytical methods and spectral analysis method. These results provide a scientific reference for generating warnings for coal mining accidents based on economic indices. PMID:27902748

  14. The Steam Coal Market in 2016: the Supply Shock

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2017-03-01

    Surprising coal markets: while the world coal demand is diminishing, the steam coal price doubled in 2016. After five years of uninterrupted price decline and a sluggish world demand, this strong price hike might appear as paradoxical. This paper explains the principal reasons for this situation. After five consecutive years of decline, international steam coal prices doubled in 2016. The main reason is not an increase in global coal consumption, which has been declining since 2014, including in 2016, but the tightening of supplies in the narrow international coal market. Policy changes in China have played a key role. To limit production over-capacity and halt the decline in domestic coal prices, the Chinese government has mandated a reduction in the number of working days in Chinese mines from 330 to 276. This decision has led to a fall in domestic production. Faced with rising coal demand in summer 2016, and surging domestic coal prices from end of June, China once again turned to the international market to cover its supply needs. It thus became again the world's largest coal importer, outpacing India. The increase in Chinese imports did not prevent Chinese demand from falling for the third consecutive year. On the supply side, after five years of declining prices, the export capacities of the main coal supplying countries have been reduced by mine closures, corporate bankruptcies and investment reductions in the sector. This led to the scissor effect observed in 2016, characterized by a sudden and unexpected increase in Chinese imports combined with a supply squeeze. Coal prices surged in the third quarter of 2016, before starting to decline. They have stabilized since December 2016, albeit at high levels. The decline could continue after winter 2016-17. The Chinese government intends to control the level of domestic coal prices to limit their impact on electricity prices and inflation. It has, therefore, relaxed its control on coal production, which has had

    2005-01-01

    The impact of rising natural gas prices on the United States economy and domestic industries was examined in this PowerPoint presentation. Industry comments were solicited on the effects of natural gas prices on their business performance from 2000 to 2004 in order to collect data, and macroeconomic impacts were determined through the use of an inter-industry model. Results of the survey and subsequent model suggested that in 2000 and 2001, real gross domestic product (GDP) growth was depressed by 0.2 per cent because of higher natural gas prices. Between 2000 and 2004, the civilian workforce was lower by 489,000 jobs. It was determined that nitrogenous fertilizer manufacturing was the most gas intensive industry. The results indicated that higher natural gas prices were an additional burden on manufacturing industries, and that the economic performance of natural gas intensive industries was poor between 2000-2004. However, it was just as poor between 1997-2000, when gas prices were relatively low and stable. Natural gas intensive industries passed along price increases in their products to their downstream consumers. Despite job losses, wages in natural gas intensive industries were higher and grew faster than in the rest of the manufacturing industry in the 2000-2004 period. Although capital expenditures declined between 2000 to 2004, they declined more rapidly in the 1997-2000 period. There has been no evidence of a decline in international competitiveness of natural gas intensive industries. It was concluded that rising natural gas prices have had a significant impact on the growth of the economy and workforce. tabs., figs

    For coal-fired power plants, the application of blended coal combustion has been a great issue due to the shortage and rising prices of high-rank coal. This paper describes the optimization of blending methods between Xing'an lignite coal, Shaltala lignite coal, Ura lignite coal, and Inner Mongolia bituminous coal. The multi-objective decision-making method based on fuzzy mathematics was used to determine the optimal blending ratio to improve the power plant coal-fired economy.

    Highlights: • This study evaluates the coal-electricity pricing linkage policy in China. • Six stochastic frontier cost models are used to estimate efficiency measures. • The coal-electricity pricing linkage scheme is a double-edged sword. • We suggest the threshold value of 5% or group specific. - Abstract: This study evaluates the feasibility and fairness of 2012 amendment to coal-electricity pricing linkage policy in China. Our empirical design is based on several stochastic frontier cost functions and the results show that the amended pricing linkage scheme is a double-edged sword as follows. On the one hand, it provides incentives for less-efficient (with efficiency less than 90%) power plants to increase their efficiency. One the other hand, it imposes a penalty to highly-efficient power plants (with efficiency more than 90%). And even worse, the higher the efficiency is, the bigger the penalty will be. To make the current coal-electricity pricing linkage scheme more feasible, we suggest the threshold value of 5 instead of 10%, and a group specific threshold value instead of the current one-size-for-all practice

    This paper examines whether some elements of Japan's resource acquisition strategies might have caused price and other distortions of market behaviour in the Pacific metallurgical coal trade. The industry chosen for investigation is that of steel manufacture, and the traded resources commodity examined is coking coal, which is the primary energy input for blast furnace iron making. Regression modelling studies to determine historic acquisition value and quality relationships for US, Australian and Canadian coals sold into the Japanese coking coal market are described. Departures from normal demand response behaviour to price competitiveness are also investigated. 3 figs., 3 tabs.

    This survey was conducted to analyze the future trends of export prices of steam coal and thereby to contribute to security of stable supply of coal by collecting overseas information from relevant organizations, e.g., history of coal futures transactions in USA, and backgrounds, trends and evaluation thereof; and correspondence of the Australia's government and coal industry to depressed coal prices, actual situations of the country's mining industry and coal production, and their opinions on coal transaction contracts. Australia is the most important and hence influential coal supplier for Japan, and the country's coal industry is now in shaky conditions of reorganization. Chapter 1 describes shift from benchmark transactions to individual negotiations to determine steam coal prices since FY 1998, Chapter 2 takes up trends of coal futures transactions the US markets are adopting, Chapter 3 analyzes trends of steam coal prices in Australia, and Chapter 4 prospects future trends of steam coal markets and prices in Australia. The future coal prices will fluctuate periodically, but will be generally subjected to downward pressure in the medium term. (NEDO)

    In recent years, there has been a convergence of international trade with traditional domestic markets, with import increasing into many coal producing regions, the influence of trade on domestic markets has been twofold. Firstly, imported coal displaces domestic production, and in doing so, secondly international price trends may drive prices of what remains of the indigenous market for coal. While international trade does not provide any additional benefits in terms of reduced CO2 at a coal-fired power stations, importing coal provides many benefits, such as cost savings, improved coal quality, enhanced supply diversity, and often fills a gap which is left where domestic supply is unable to fulfil. This report examines the various factors that have led to rise in popularity of seaborne-traded coal, and seeks to discuss the future of domestically produced coal in some of the major coal markets of the world.

  1. Defining geographic coal markets using price data and shipments data

    2005-01-01

    Given the importance of coal in world energy supply an analysis of the relevant geographic market is essential for consumers, producers, as well as for competition policy. The purpose of this paper is to define the relevant economic market for steam and coking coal, and to test the hypothesis of single world markets for these coal products. Methodologically the paper relies on two different tests for defining markets, using both shipments data and price data. The results from both methods point in the same direction. In the case of coking coal the results indicate that the market is essentially global in scope, and also that the market has become more integrated over time. The results for steam coal show that the market is more regional in scope, and there exist no clear tendencies of increased integration over time. One policy implication of the finding that the steam coal market is more regional in scope, and thus that the market boundary is smaller than if the market would have been international, is that a merger and acquisition in this market likely would have been of a more concern for antitrust authorities than the same activity on the coking coal market

  2. Oil Price Rise and the Great Recession of 2008

    Full Text Available The financial crises of 2007-2008, caused wide-spread falling output and unemployment, in the affected countries and also globally. The severity of the recession was such that it was called the “Great Recession”. As a result of an increase in demand from China and India, at the same time, oil prices rose significantly. The empirical results from this study show that oil price changes negatively affected global growth rate in the 1970s but not in the 1990s and 2000s. These results suggest that the Great Recession in 2008 that initiated by the financial crises, was independent of a significant rise in oil prices.

  3. Coal contract cost reduction through resale of coal

    The weak coal market of the 1980's has enabled utilities and other users of coal to enjoy stable or falling prices for coal supplies. Falling prices for coal stimulated the renegotiation of numerous coal contracts in recent years, as buyers look to take advantage of lower fuel prices available in the marketplace. This paper examines the use of coal resale transactions as a means of reducing fuel costs, and analyzes the benefits and risks associated with such transactions

    Researchers of Peak oil warn about imminent worldwide coal shortages as of 2025. Countries that fully depend on coal import, such as the Netherlands, run great risks due to strongly rising prices and insecurity of supply. How large is the supply of extractable coal? How long will extraction and export continue undisturbed under increasing demand? What effect will this have on the coal price? The real data on supply, demand, price and export mainly tell a tale of unreliable reserves and high prices according to Greenpeace. (mk) [Dutch] Onderzoekers van Peakoil waarschuwen dat vanaf 2025 wereldwijd kolentekorten dreigen. Landen die volledig afhankelijk zijn van de import van kolen, zoals Nederland, lopen een groot risico door sterk stijgende prijzen en onzekere levering. Hoe groot is de winbare kolenvoorraad? Hoe lang gaan winning en export ongestoord door bij een groeiende vraag? Wat betekent dit voor de kolenprijs? De werkelijke gegevens over voorraad, vraag, prijs en export vertellen volgens Greenpeace vooral een verhaal van onbetrouwbare reserves en hoge prijzen.

    In 2013, China opened pilot carbon emission trading markets in seven provinces, where carbon emission allowances have now been traded for more than two years. In this paper, we employ a structural VAR model and the price of the Beijing carbon emission allowance to study the dynamic relationships among the price of the carbon emission allowance, economic development and the price of energy. This paper's data cover the period from April 2, 2014 to November 6, 2015. This paper provides information that will be helpful to both investors and governmental policy makers. The results show that (1) an increase of one standard deviation in the coal price leads to an initial increase of approximately 0.1% in the Beijing carbon price. After 2 days, there is a decrease of less than 0.1%, and the price gradually increases by approximately 0.1% after 30 days; (2) the price of the Beijing carbon emission allowance is mainly affected by its own historical price; (3) the Beijing carbon emission allowance price, crude oil price, natural gas price and economic development have positive – albeit non-significant – correlations. - Highlights: • This paper examines the response of the Beijing carbon emission allowance price. • A rise in coal prices will have different effects in different lag stages. • There are positive correlations between the BJC and economic development.

  6. Growing Chinese coal use: Dramatic resource and environmental implications

    2010-01-01

    Chinese coal consumption continues to rise as the country's economy and industry expand. Coal is particularly critical for China's fast-growing power sector, generating about 80% of electricity output. Notwithstanding the importance of coal and electricity, many international forecasts today underestimate their rising use in China. This paper acknowledges the current world financial crisis and assumes that Chinese GDP growth to 2025 will not again approach double-digit levels. Using the scenario analysis, this paper demonstrates that even with conservative assumptions about Chinese GDP growth and income elasticity of electric demand to 2025, the country will likely experience much higher coal demand and emit much greater volumes of carbon dioxide than forecast by various international energy agencies. The paper also analyzes how China's domestic coal reserves may be threatened within two decades, possibly affecting long-term economic growth in China, as well as world coal prices.

  7. Influence of rising commodity prices on energy policy

    Keppo, I.J.

    2009-04-01

    During the past few years we have first witnessed a rapid increase in the prices of commodities and then later, as a consequence of the economic downturn, an even more drastic drop. Simultaneously with the commodity price increase, an increase in the investment costs of power plants was experienced. The rise in material costs was often stated as one of the reasons for this increase. In this study the relationship between commodity costs and energy prices is studied. A bottom-up approach is used for estimating what kind of an impact increased commodity prices alone could be expected to have on the investment costs on the one hand, and how increased energy prices may affect commodity production costs on the other. The results indicate that although the commodity production costs usually have a fairly large energy component, even high increases in commodity prices, and therefore raw material costs of power plant investments, can not explain the recently experienced hikes in power plant investment costs; a doubling of the costs of the main raw material flows could explain an investment cost increase of some 5-10%, depending on the power plant type. This would seem to indicate that other contributing factors, such as bottlenecks in the production of power plant components, may play an important role in the recent investment cost increase

  10. Australia/Japan thermal coal settlements

    International Nuclear Information System (INIS)

    McLean, A.

    2000-01-01

    After prolonged negotiations, Australian suppliers and Japanese buyers have reached agreement on the benchmark thermal coal prices for the Japanese financial year 2000 (April 1, 2000 to March 31, 2001). The benchmark price as negotiated with the Chubu and Tohoku power utilities is about US$1.20 down on last year's price of $29.95. The actual price change to each supplier varies slightly depending on the calorific value of each product as calculated against a benchmark value of 6700kcal/kg on a gross air-dried basis. It is strange, but the Australians and Japanese both have some reason to crow about the outcome of the negotiation. In US dollar terms, compared with April 1, 1999, the suppliers have secured a price rise from A$45.39 to A$47.97; while the Japanese can point to having achieved a price reduction from Y3551/t to Y3162/t. The joys of exchange rate fluctuations. The result can only be seen as a good one for Australia, especially as it is alleged that one of the Australian suppliers opened negotiations by putting a US$1 price reduction on the table. It is worth noting that the significance of the benchmark coal price is waning, with the annual negotiations in Japan covering only 14Mt of a total seaborne trade of some 450Mt. Consequently, few tonnes are marketed at the benchmark price and Australia finds itself in fierce competition with suppliers from Indonesia, China and Russia for huge, short-term tenders at FOB prices. Recent winning Australian bids have been barely over US$20/t FOBT ex east coast Australia-nearly 30% below the new US$28.75 benchmark price. Finally, on the negotiating table will come the settlements for the semi coking coals. This is where Australia should hold the trump card. Japan simply cannot replace, from other countries, the near 30Mt of high quality coal it purchases each year from Australia. But already the whiff of a US$1.45-US$1.50 price reduction hangs in the air. Copyright (2000) Australian Journal of Mining

    Full Text Available The purpose of this research is to analyze the effect of fundamental and macroeconomic analysis on stock price. The research was conducted at a coal company listed on the Indonesia Stock Exchange. Fundamental analysis measured by current ratio, debt to equity ratio (DER, earning per share (EPS, return on assets (ROA, and total assets turnover (TATO, while macroeconomic analysis is measured by inflation and exchange rate.  Current ratio (CR has a positive effect on Stock Price. Strengthening this level of liquidity can provide information to investors to decide to buy shares of companies that tend to be healthy and stable. Return on assets (ROA has a positive and significant influence on stock price. Efforts to maximize the level of profitability by increasing the value of return on assets can provide information to investors that investments invested in the company will provide good profit. The impact of stock prices will rise. While debt to equity ratio (DER, earning per share (EPS and total assets turnover (TATO have no effect on Stock Price.  Macroeconomic analysis shows: (a Inflation rate has no effect on stock price of coal company. This can be because the inflation rate in Indonesia is at the level of 6% -7% per year and included in the category of mild inflation. Mild inflation resulted in very slow economic growth, not affecting stock prices. The exchange rate has a negative and significant effect on coal company stock price. If the Rupiah is depreciated then the stock price of the coal company will decrease.

  13. Does climate policy make the EU economy more resilient to oil price rises? A CGE analysis

    International Nuclear Information System (INIS)

    2012-01-01

    The European Union has committed itself to reduce greenhouse gas (GHG) emissions by 20% in 2020 compared with 1990 levels. This paper investigates whether this policy has an additional benefit in terms of economic resilience by protecting the EU from the macroeconomic consequences due to an oil price rise. We use the GEM-E3 computable general equilibrium model to analyse the results of three scenarios. The first one refers to the impact of an increase in the oil price. The second scenario analyses the European climate policy and the third scenario analyses the oil price rise when the European climate policy is implemented. Unilateral EU climate policy implies a cost on the EU of around 1.0% of GDP. An oil price rise in the presence of EU climate policy does imply an additional cost on the EU of 1.5% of GDP (making a total loss of 2.5% of GDP), but this is less than the 2.2% of GDP that the EU would lose from the oil price rise in the absence of climate policy. This is evidence that even unilateral climate policy does offer some economic protection for the EU.

    This document proposes an analysis of the prices increase on the coal world market since the beginning of the second half-year 2003. Many phenomena can explain this increase: supply problems in China, a poor availability of cargoes, an increase of the european importations for the electric power production, a high demand of the japanese power plants, social movements at the Kaltim Prima mine and uncertainties on the coal availability in Poland.

  16. Effects of an oil price rise on inflation, output, and the exchange rate in the case of subsidization policy

    Zandi, F R

    1982-01-01

    Since the Organization of Petroleum Exporting Countries raised the price of oil by 400% in 1974, the theory of supply inflation has received a great deal of attention. This study analyses the short and long run effects of an oil price rise on output, inflation, and the exchange rate. The study also analyses dynamic adjustments to the oil price rise in cases where oil-price subsidies are provided and where no subsidies are provided. In the no-subsidy case it is shown that the oil price rise can be inflationary or deflationary. The implications of the policy of subsidizing the price of oil is highlighted by taking account of a government budget constraint which in turn leads to the possibility of monetization as a source of financing the deficit, and thereby to higher output relative to the no subsidy case. As to the price level, the possibility is illustrated that subsidization can actually be more inflationary. The important element giving rise to the above possibility is the subsidy induced increase in the money supply. Exchange-rate flexibility is shown not to insulate the domestic price level against an oil price rise. In the long run the rate of inflation and exchange-rate variations are determined by the rate of growth of the money supply. The dynamic adjustment path of price and output is shown to be determined by the rate of adjustment of inflationary expectations.

  17. Pricing structures in US coal supply contracts

    Science.gov (United States)

    Kacker, Kanishka

    The subject of my dissertation is the study of coal procurement by electric utilities in the US over 2 decades, from 1979 to 2000. Energy markets are typically characterized by severe contracting problems. Buyers and sellers therefore employ various instruments, such as contract length or complex pricing arrangements, to restrict these problems. Relationship specific investment, wherein buyers make investments specific to their suppliers, has been advanced as a prominent explanation for contractual length. Investment decisions are however endogenous in length or pricing, making causal identification of the role of investment specificity difficult. In my first chapter, I attempt a resolution. I use the 1990 Clean Air Act Amendment as an exogenous shifter of the extent of relationship specific investment. A key feature of the Amendment's design helps me define a difference-in-difference model arguably free of the endogeneity issues discussed above. I find that the plants forced into switching - Phase I plants located in the US Midwest - are more likely to choose fixed price contracts than those that were not. Further they also write contracts of shorter terms, with the reduction being approximately 30%. Considerably little is known about the performance implications of contractual choices. These form the basis for Chapter 2. Here I find prices to be lower, by between 5% to 20% of the total transaction price, but the probability of renegotiation higher, under fixed price contracts than under escalator or cost-plus contracts. Contract choices appear consistent with a trade-off between establishing incentives ex-ante and lowering negotiation costs ex-post, with relationship specific investments in particular making such a trade-off compelling. Chapter 3 considers the regulatory environment these utilities were subject to. Both incentive based regulation as well as the restructuring of electricity generation are smaller in comparison to relationship specific investment

    Unless this giant nation embraces a new strategy for producing and using energy. Its fast-growing economy could overwhelm international efforts to control greenhouse warming. Carbon emissions in China have increased 65% in the past decade, largely due to a sharp rise in coal burning. China's growing economy, low energy prices, and government policies are fueling the increase in coal use. China's leaders dismiss the notion that concern over global warming should alter their energy strategy. However, the important question is not whether the Chinese have the right to follow a carbon-intensive energy path, but whether it is in their interest to do so. Raising energy efficiency is essential to boost living standards; more efficient industrial processes, maintainance, operating procedures, and energy efficient construction all are needed. In the long run China will need to develop its own alternatives to coal;natural gas, solar, wind, biomass, and geothermal energy all have enormous potential. Price adjustments, international support, and education will all be needed in the long run

    Energy conservation technologies in the coal-fired power sector are important solutions for the environmental pollution and climate change issues. However, a unified framework for estimating their costs and potentials is still needed due to the wide technology choices, especially considering their economic feasibility under fuel and carbon price uncertainties. Therefore, this study has employed a bottom-up approach to analyze the costs and potentials of 32 key technologies’ new promotions during the 13th Five-Year Plan period (2016–2020), which combines the conservation supply curve (CSC) approach and break-even analysis. Findings show that (1) these 32 technologies have a total coal conservation potential of 275.77 Mt with a cost of 238.82 billion yuan, and their break-even coal price is 866 yuan/ton. (2) steam-water circulation system has the largest energy conservation potential in the coal-fired power industry. (3) considering the co-benefits will facilitate these technologies’ promotions, because their break-even coal prices will decrease by 2.35 yuan/ton when the carbon prices increase by 1 yuan/ton. (4) discount rates have the largest impacts on the technologies’ cost-effectiveness, while the future generation level affect their energy conservation potentials most. - Highlights: • The 32 technologies can save 275.77 Mt coal with a cost of 238.82 billion yuan. • The steam-water circulation system has the largest energy conservation potential. • Considering the co-benefits will facilitate the technology promotions • Discount rates have the largest impacts on the technologies’ cost-effectiveness.

    1982-05-01

    The relationship between energy price and consumption was studied, especially reactions to oil price rises in the 1970's. Industrial, domestic, and road transportation energy consumption were examined. Until 1973, consumption rose steadily, while the inflation-adjusted price dropped. Immediate reaction to the two large price rises was a drop in consumption, but overall consumption continued to grow when the growth in total energy consumption was reversed. This change is due to adverse business conditions, displacement of coal by oil, oil by gas, and mineral fuels by electricity in given sectors, switches to less energy intensive activities, a change in the mix of gross national products, and weather conditions, as well as by price rises. Energy conservation measures had little impact.

    Motor vehicle accidents are the leading cause of death among young adults. Although automobile fatalities have declined in recent years, motorcycle fatalities are rapidly increasing. The purpose of our research was to quantify the relationship between changing fuel prices and motorcycle fatalities. Our findings suggest that people increasingly rely on motorcycles to reduce their fuel costs in response to rising gasoline prices. We estimate that use of motorcycles and scooters instead of 4-wheeled vehicles results in over 1500 additional motorcycle fatalities annually for each dollar increase in gas prices. Motorcycle safety should receive more attention as a leading public health issue. PMID:19696374

    The year 2012 benefited from a growth of the consumption of hard coal at the national level as well as at the international level. Worldwide, the hard coal still is the number one energy source for power generation. This leads to an increasing demand for power plant coal. In this year, the conversion of hard coal into electricity also increases in this year. In contrast to this, the demand for coking coal as well as for coke of the steel industry is still declining depending on the market conditions. The enhanced utilization of coal for the domestic power generation is due to the reduction of the nuclear power from a relatively bad year for wind power as well as reduced import prices and low CO{sub 2} prices. Both justify a significant price advantage for coal in comparison to the utilisation of natural gas in power plants. This was mainly due to the price erosion of the inexpensive US coal which partly was replaced by the expansion of shale gas on the domestic market. As a result of this, the inexpensive US coal looked for an outlet for sales in Europe. The domestic hard coal has continued the process of adaptation and phase-out as scheduled. Two further hard coal mines were decommissioned in the year 2012. RAG Aktiengesellschaft (Herne, Federal Republic of Germany) running the hard coal mining in this country begins with the preparations for the activities after the time of mining.

    For three years, international hard coal prices have been at rather expensive levels. Some argue that these higher prices might indicate the threat of a physical scarcity of fossil fuels - similar to the situation with oil and gas. This is not true. The supply situations with lignite and hard coal appear to be largely not critical. Adjusted to the rise in global coal consumption, which is expected until 2100, nature by and large can meet the world's coal demand. This is shown for lignite in this article and it is illustrated for hard coal here, differentiated in space and time for a world divided into eight regions and viewed for the years 2005, 2020, 2030, 2050, and 2100. The only area of potential concern is Asia (especially China). But today's and coming eager efforts in China to convert coal resources into reserves will most likely deliver the coal needed for the Chinese market. Up to the year 2100, and from a geoscientific point of view, there will be no bottleneck in coal supplies on this planet. (author)

  5. Coal liquefaction policy in China: Explaining the policy reversal since 2006

    2011-01-01

    China has emerged as a leader in coal liquefaction. While the country's abundant coal resources and acute concerns about oil security help explain China's interest in liquefaction, the driving forces for this industry are complicated and policy has been inconsistent. Since 2006 Beijing has tried to slow down the development of liquefaction; even as China has become more dependent on imported oil, the central government has been wary about the large impact of liquefaction technologies on scarce resources such as water. However, local government officials in coal rich areas have strong incentives to pour investment into the technology, which helps explain the uneven development and policy. The future of coal liquefaction will depend on how these forces unfold along with major Beijing-led reforms in the Chinese coal industry, which is closing smaller mines and favoring the emergence of larger coal producing firms. Those reforms will have mixed effects on liquefaction. They temporarily contribute to higher prices for coal while over the longer term creating coal companies that have much greater financial and technical skills needed to deploy technologies such as coal liquefaction at a scale needed if this energy pathway is to be competitive with conventional sources of liquid fuel. - Highlights: ► We explain swings in Chinese policy on coal liquefaction, a possible substitute for imported oil. ► Since 2006 Beijing's support has waned due to fears about environmental impacts and cost of liquefaction. ► Local governments in some coal rich regions remain strongly supportive. ► Volatile oil prices and rising coal prices make this industry more risky than previously thought. ► Consolidation of the coal industry will have mixed effects on viability of liquefaction projects.

    Analyses the most important economic parameters of the main pyrolysis processes. Considers the markets available for semi-coke and tars. Concludes that no single technology or process has clear advantages over the others because all depends on the type of coal being used and the purpose for which the end product is to be used. Refers to studies carried out in Canada and the USA on the same subject and reports their findings. Concludes optimistically that coal pyrolysis shows promise of being economically viable in the future because although initially, costs reflect the high financial outlay necessary to begin operations, after a certain period, these costs fall and the end product can be sold at a lower price. A further point in favour of pyrolysis is that coal prices are likely to rise more slowly than oil prices. 5 refs., 8 tabs.

    Traditionally considered the cheapest fuel around, the market price for coal ignores its most significant impacts. These so-called 'external costs' manifests themselves as damages such as respiratory diseases, mining accidents, acid rain, smog pollution, reduced agricultural yields and climate change. The harm caused by mining and burning coal is not reflected in its price per ton or its costs for a kWh of electricity, but the world at large is nevertheless paying for it. This report seeks to answer the question: just how much are we paying?

    In recent years, there has been a convergence of international trade with traditional domestic markets. As imports continue to increase in many coal producing regions, the influence of trade on domestic markets has been twofold. Firstly, imported coal displaces domestic production and, secondly, international price trends may drive prices of what remains of the indigenous market for coal. While international trade does not provide any additional benefits in terms of reduced CO2 at coalfired power stations, importing coal provides many benefits, such as cost savings, improved coal quality, enhanced supply diversity, and often fills a gap which domestic supply is unable to fulfil. This report examines how coal markets have evolved over the decades with utilities and heavy industry moving away from their seemingly secure yet captive markets of domestic coal to procuring more supplies from the international market to satisfy the need of cost reduction and better and consistent quality of fuel product. The various factors that have led to a rise in popularity of seaborne traded coal, and the future of domestically produced coal in the Pacific market are discussed. This is in one of three reports which examine the changing trends in coal imports over the long term in three geographical regions: a global perspective, the Atlantic market and the Pacific market.

    The global financial crisis in 2008 sent commodity markets spinning which caused demand to erode, price levels to quickly plummet and project financing costs to rise. In this paper, the authors examine the impacts the economic slowdown has had on the global seaborne hard coal market looking at the impacts for both coking (metallurgical) and thermal (steam) coals including pricing, supply availability, demand and aggregated mine level production costs. The hard coal market experienced a significant slow down; the commodity has bounced back strongly in 2010 driven by strong Asian demand at growth rates above historic levels and strong projections for the future.

  15. The two faces of coal : uncertainty the common prospect for metallurgical and thermal coal

    2010-01-01

    Although the methods of producing thermal and metallurgical coal are the same, metallurgical coal is destined to cross the world for steel manufacturing and thermal coal is destined for power plants close to where it was mined. This article discussed the factors influencing the price of these 2 coals. The production of thermal coal can remain steady during an economic crisis because coal-fired power plants generally provide low-cost-base-load electricity that remains stable during economic cycles. However, the demand for metallurgical coal is more volatile during an economic crisis because it is directly related to the demand for steel products in the construction and automotive industry, which are very sensitive to the state of the economy. There have been recent indications that Canada's export market for thermal coal is on the rise. In 2008, China became a net importer of coking coal. China's need for more coal to fuel its growing economy despite the global economic slowdown has meant that producers are diverting excess supply from European markets to China. Higher-end thermal coal offers low sulphur content and higher energy content, both desirable traits for power utilities facing strict emissions control. In addition to having huge reserves of very high-quality coal that is becoming increasingly important to China, Canada has the advantage of having the available transportation capacity in its west coast terminals and on its rail network. 3 figs.

    conventional reserves of fossil fuels. Coal contributes to the economic activity and employment in the region. The EU mining industry employs 260,000 workers (direct jobs) and the turnover of the whole coal industry is estimated at Euros 25 billion a year. Coal prices, despite their rising trend in the past few years, are much lower than competing fuels: half the price of natural gas imported in Europe. As coal ensures safe, reliable, affordable and sustainable energy for all, it will be very much needed in the years to come. However, coal is proscribed in a CO 2 -free environment. Its combustion in thermal power plants - its main outlet in Europe - emits twice as much CO 2 as gas plants. Although a lot of R and D work is done to capture CO 2 emissions from coal plants and store it, no zero emission commercial plants have yet started operation. Several CCS projects have been delayed, or even cancelled, in the past few years due to regulatory uncertainties, a lack of funding and public opposition to CO 2 storage. The current European economic crisis and the large sovereign debts have also reduced public funding in CCS projects. The future of coal in Europe is therefore very uncertain. Will CCS development allows it to remain a fuel of choice, given large available reserves at low prices, compared with competing energy sources? Or will coal disappear from the European energy mix? How fast will the decline in European coal production be? This report looks at these issues and highlights some facts, trends and regulation that may affect the supply and demand of coal in the future. The analysis concentrates on steam coal used to generate electricity, since the power generation sector is by far the largest user of coal in Europe. The first part of this report looks at the European coal market region-wide. Chapter 1 describes the EU coal market in the global context. Chapter 2 analyses the significance of the European coal mining industry and its future after the end of state aid

    An 87% of the total energy requirement of the world is supplied by fossil fuels such as coal, fuel oil, and natural gas, while the rest comes from the other sources, like hydroelectric and nuclear power plants. Coal, as a fuel oil equivalent, has the greatest reserves (70%) among the fossil fuels and is very commonly found in the world. While the share of coal in the production of electricity was 39% in 2004 it is expected to rise to 48% in 2020. In the direction of sustainable development, the utilization of coal in energy production is constantly increasing and related researches are continuing. Today, the development and economics of hybrid electricity production; gas, fluid fuel, and hydrogen production from coal are being investigated and their industrial applications are slowly emerging. The surprisingly sharp increase in fuel oil and natural gas prices proves the defectiveness of the energy strategies of Turkey in effect since the 1990. Turkey should turn to coal without wasting more time, accept the utilization of clean coal in energy production, and determine her road-map. Increasing the efficiency of thermal power plants which utilize coal; hybrid technology; and gas, fluid fuel, and hydrogen production technologies from coal are investigated in this paper and suggestions are made.

    1995 Uranium Spot Market volume increased by 7.8 million lbs U308 equivalent from 1994 levels to over 42.1 million lbs U308 equivalent the largest since 1991. This increased volume was accompanied by increased prices. The restricted market price rose by over $2.20/lb U308 from the January range of $9.75-$10.00 per lb U308 to the December range of $11.95-$12.25 per pound U308. The unrestricted market price rose by over $2.65/lb U308 from the January range of $7.15-$7.30 per lb U308 to the December range of $9.80-$10.15 per pound U308. Unrestricted prices rose at a relatively steady pace each month for the first half of the year and at a greater pace through the second half of the year, while restricted prices rose faster during the first half of the year and leveled out during the second half of the year. The result was a partial closure of the gap between restricted and unrestricted prices

    Participants in the Pacific market have much to gain by understanding how and why coal prices fluctuate. This presentation addressed market issues pertaining to the supply and demand for coal. It discussed commoditisation, the process by which a product moves from being a unique or differentiated product to a commodity. While price volatility is a measurement of the change in price over a given time period, it is often expressed as a percentage and computed as the annualized standard deviation of percentage change in daily price. This price volatility and its causes was also reviewed. The driving forces of commoditisation include demand for price transparency; change from traditional buying and selling patterns; and external factors. Price volatility occurs when logistics have not kept pace with product flow. Volatility can be attributed to supply and demand speculation, margin calls and the link between the price of coal and other fossil fuels, especially in Europe. The demand for price transparency as well as the change from traditional buying and selling patterns were discussed. It was concluded that the volatility of coal prices will increase as coal becomes increasingly affected by the global energy market. tabs., figs

    Many people believe that China's economic growth can continue almost indefinitely. For a manufacturing-based economy such as China's to continue to grow, it needs an adequate supply of inexpensive energy. To date, this energy growth has primarily come from coal, but China's indigenous coal supplies are now falling short of the amount needed to support this growth. In this situation, the status of China's future coal supply will be very important for China's future economic development. Our analysis shows that China's ultimate recoverable coal reserves equal 223.6×10 9 MT, and its production will peak between 2025 and 2030, with peak production of approximately 3.9×10 9 MT. The extent to which China can import coal in the future is uncertain. With rising coal demand, this combination is likely to create a significant challenge to China's future economic development. - Highlights: ► We analyze an issue of prime importance for the future of China's economy. ► The decline in coal supply will present a challenge to China's economic growth. ► Rising coal price will also have an adverse impact on economic growth

    Kobe Steel's (Kobelco) corporate strategy includes expanding from only-one product such as high tensile strength steel sheet, and enlarging overseas production capacity through joint ventures and technical alliances. A new steel making process from low quality iron ore and steaming coal called ITmk3 has been developed by Kobe Steel that does not require any coke, reduces carbon dioxide emissions by 20 per cent, and reduces the cost of transporting slag. This strategy and technology was presented along with the changes surrounding the Japanese steel industry and raw materials market. These changes include the rise of emerging oil-producing countries; world steel production and exports; the rise in prices of resources; and the slowdown of the United States economy. The current situation of Japanese crude steel production, pig-iron production, and coke expansion plans were also presented. The presentation also outlined expectation's of the Canadian coal industry with reference to Canadian coal imports to Japan. tabs., figs

    This paper reports that it was widely believed after the 1986 U.S. natural gas price drop that prices had to rise steeply soon because at the low prices it did not pay to replace reserves. Lack of reserves would push the price back up. This forecast raised the value of reserves in the ground. It was a mistake. Reserves were replaced because the cost had dropped so sharply that it paid to replace them. This fact was hidden by the so-called finding cost per Mcf equivalent. This is expenditures on exploration plus development, for oil and gas together, divided by the reserve-additions of oil plus gas reduced to an equivalent, usually of 6:1 but sometimes a higher ratio

    2015-01-01

    Full Text Available In order to study the impact of the rise in prices of vegetables on vegetable producers, and to increase the revenue of vegetable producers, this paper does a survey by anonymous sampling questionnaire. Results shows that: most vegetable growers think that vegetable prices should rise and would continue to rise, and that vegetable prices would increase their revenue, thus in the coming year they would expand the planting scale of vegetable variety whose increase rate is the largest in this year. But because of the increase of logistics costs and production costs, some farmers benefit very little from the rising trend of vegetable prices. Most farmers expect too much in the trend estimation of the prices of vegetables and also lack of planning and forward-looking in production, thus the planting area of single variety is often decided by the market of previous year. According to analysis of the impact of the rise in vegetable prices on vegetable producer behavior, this paper gives the following suggestions to increase revenue of vegetable producers: change the mode of thinking, improve rural information platform, and increase capital investment for vegetable production base.

    Full Text Available The article presents the impact of prices of carbon dioxide on the economic efficiency of 14 coal gasification technologies employed for producing electricity, hydrogen and methanol measured with the use of NPV method. All technical, technological and economic assumptions in the assessment have been made for Polish conditions. The impact of CO2 prices were examined in the range of 30-200 PLN/Mg. The production capacity of the base technology corresponds with the fuel consumption of indicative coal having the calorific value of 20.5 GJ/Mg, used in the amount of 100 Mg/h. On the basis of the conducted research, with respect to all technical and economic assumptions, it can be stated that for the base scale there is a clear impact of prices of CO2 emission allowances above the 90 PLN/Mg CO2. Such a level of carbon dioxide prices makes the decision concerning construction of geological sequestration systems (CCS, carbon capture and storage worthwhile. This applies in particular to the production of electric energy. For the variants focused on hydrogen production there is a dominance of variants with CCS system only at the price exceeding 120 PLN/Mg CO2, and in the case of methanol such a situation occurs above 150 PLN/Mg CO2.

    Prices of oil and other fossil fuels on global markets have reached a high level in recent years. These levels were not able to be reproduced on the basis of scenarios and prognoses that were published in the past. New scenarios, based on higher energy price trajectories, have appeared only recently. The future role of various energy carriers and technologies in energy-economic scenarios will greatly depend on the level of energy prices. Therefore, an analysis of the impact of high energy prices on long-term scenarios for Germany was undertaken. Based on a reference scenario with moderate prices, a series of consistent high price scenarios for primary and secondary energy carriers were developed. Two scenarios with (i) continuously rising price trajectories and (ii) a price shock with a price peak during the period 2010-15 and a subsequent decline to the reference level are analysed. Two types of models have been applied in the analysis. The IKARUS energy systems optimisation model covers the whole of the German energy system from primary energy supply down to the end-use sectors. Key results in both high price scenarios include a replacement of natural gas by hard coal and renewable energy sources in electricity and heat generation. Backstop technologies like coal liquefaction begin to play a role under such conditions. Up to 10% of final energy consumption is saved in the end-use sectors, with the residential and transport sector being the greatest contributors. Even without additional restrictions, CO{sub 2} emissions significantly drop in comparison to the reference scenario. The ELIAS electricity investment analysis model focuses on the power sector. In the reference scenario with current allocation rules in the emissions trading scheme, the CO{sub 2} emissions decrease relatively steadily. The development is characterised by the phaseout of nuclear energy which is counterweighted by the increase of renewable. In the high price scenario, the CO{sub 2

    The report deals with the use of coal and coke during 1996. Some information about techniques, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from SCB have also been used. The use of steam coal for heating purposes during 1996 was 1,2 mill tons and 50% higher than in 1995. The increase is probably temporary and due to high prices of electricity because of lack of water power. The co-generation plants were the main users of coal. The minor plants have increased their use of forest fuels. Probably the use of steam coal will go down in the immediate years both in the heat generating and the co-generation plants. During the top year 1987 coal was used in 18 hotwater plants and 11 co-generation plants. 1996 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in the industry has been constant at the level 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1996 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. The coke consumption in the industry was 1,5 mill tons. 0,3 mill tons of coke were imported. The average price of steam coal imported in Sweden in 1996 was 340 SEK/ton or 2% higher than in 1995. For the world, the average import price was 51,5 USD/ton, nearly the same as the year before. The contract prices for delivery during 1997 are about equal as the end of 1996. All Swedish plants meet their emission limits of dust, SO 2 and NO x given by county administrations or concession boards

    We employ system dynamics method towards a coal-chemical industry district economy evolution model, using coal industry, the coal-chemical industry, their downstream industries, and the manufacture-related service industry. Moreover, we construct energy price and policy response scenarios based on Ordos’ management experience. The results show that the energy price slump had a negative impact on the overall economic development of the coal-chemical industry district, despite promoting non-resource industries. Furthermore, policies had different effects on the industry's output value and profit. In the long-term, developing alternative industries (AI) helps increase the industrial output value and profit. Decreasing value added tax (VAT) has immediate results and a distinctive effect on industrial short-term production value and profit, its long-term effect being limited. The effect of production limit (PL) on industrial profit is stronger than output value, and financial support (FS) is more conducive to improve the latter. However, coal mining and coal-chemical loan increases decrease the gross industrial profit level. Technology innovation (TI) has the best individual policy overall effect on production value and profits. Furthermore, the simultaneous implementation of PL, TI and AI can generate the synergy effect for each of them. And the simultaneous implementation of VAT and one or couple of other policies will generate the crowding-out effect both for VAT and other policies. - Highlights: • A system dynamics model of the coal-chemical industry district economy evolution in Ordos is constructed. • The impact of coal and oil prices slump on the output value and profit of each industry is revealed. • The differences in the effects especially cumulative effects of different response policies are clarified. • The crowding-out and synergy effects of policy implementation are analyzed.

    Coal consumption is growing up so fast and coal reserves are so abundant that coal might overtake petroleum in the future. The worldwide environment will not gain anything in this evolution except if 'clean coal' technologies make a significant jump. What is the driving force of this coal development? The pitfall encountered by nuclear energy and the rise of natural gas prices have been favorable conditions for the development of coal but they cannot hide the worldwide metamorphosis of coal industry. From China, undisputed world leader, to the USA, without omitting India, Russia and the big exporting countries (Australia, Indonesia, South Africa, Colombia), a new map is drawing up. In all these countries, coal companies are concentrating and internationalizing, open new strip mines and new commercial paths. The understanding of this metamorphosis has become one of the keys of the energy prospective and geopolitics of the 21. century.

    There is an urgent need to examine the role that coal might play in meeting world energy needs during the next 20 years. Oil from the Organization of Petroleum Exporting Countries (OPEC) can no longer be relied upon to provide expanding supplies of energy, even with rapidly rising prices. Neither can nuclear energy be planned on for rapid expansion worldwide until present uncertainties about it are resolved. Yet, the world's energy needs will continue to grow, even with vigorous energy conservation programs and with optimistic rates of expansion in the use of solar energy. Coal already supplies 25% of the world's energy, its reserves are vast, and it is relatively inexpensive. This study, with the aid of reports from the World Coal Study (WOCOL) examines the needs for coal on a global scale, its availability past and present, and its future prospects

    The U.S. coal industry is stable and efficient, and in good position to respond to any increase in export demand over the next ten years. After the 1973 and 1978--79 oil price increases and the resulting growth in world demand for coal, the industry responded with extensive investment in coal mines; the transportation industry similarly made large investments in coal handling equipment and port facilities. However, as a result of the expansion in world production facilities and the less than anticipated growth in coal demand, the United States now has excess capacity---in the mining, transport and port terminal industries. The coal industry's large capital investments, followed by cost cutting improvements in response to excess capacity, have paid off in greatly increased productivity. Between its low point in 1978, and 1985, average tons per miner-hour grew by 55 percent, or at an average annual rate of 6.4 percent. This gain has been passed on to coal customers in the form of lower prices. Between 1976 and 1985, FOB mine prices in constant dollars declined by 26.9 percent, or at a rate of 3.4 percent per year; the trend continued in 1986 with an additional 4.8 percent price decline

    Coal and gas continue to play a significant role in the European power generation system, especially in Germany. According to the AG energy balances, the share of hard coal in German gross electricity generation in 2016 was 17.2% and natural gas 12.4%. In addition to the CO{sub 2} price, the prices for steam coal and natural gas are a key factor in determining which gas or coal power station is in Merit Order and whether it comes to a fuel switch. Declining gas prices have been rising sharply since the middle of 2016, and the volatile prices for steam coal have been rising. This article discusses the developments and factors responsible for these developments, which could be expected in the near future, and the implications for the gas-coal spread in the electricity market. [German] Kohle und Gas spielen weiterhin eine bedeutende Rolle im europaeischen Stromerzeugungssystem, insbesondere in Deutschland. Laut AG Energiebilanzen lag 2016 der Anteil der Steinkohle an der deutschen Bruttostromerzeugung bei 17,2 % und der von Erdgas bei 12,4 %. Neben dem CO{sub 2}-Preis sind die Preise fuer Kesselkohle und Erdgas massgeblich dafuer verantwortlich, welches Gas- bzw. Kohlekraftwerk welche Position in der Merit Order einnimmt und ob es zu einem Fuel Switch kommt. Sinkende Preise beim Gas stehen seit Mitte 2016 stark gestiegenen und volatilen Preisen fuer Kesselkohle gegenueber. Dieser Artikel diskutiert, welche Entwicklungen und Faktoren fuer diese Entwicklungen verantwortlich sind, womit in naher Zukunft zu rechnen sein koennte und welche Implikationen dies fuer den Gas-Kohle-Spread im Strommarkt hat.

  14. Quality aspects of thermal coal marketing

    International Nuclear Information System (INIS)

    Dunstone, D.

    1998-01-01

    Australia's thermal coal industry is under increasing competition. A successful marketing strategy must distinguish the product from that of Australian competitors, leaving the buyer in no doubt as to its value. The marketing of thermal coal is a very different experience and encompasses an interesting commercial and technical mix. The technical merits of a coal may be effectively used to prepare the way for a sale. However, once the technical hurdle is passed (i.e. the coal is classified as acceptable), the three factors which influence the sale are price, price and price. The other aspect of marketing is that marketing, especially technical market support, must realize that the buyer often has no experience in using the coals purchased. This is particularly true with thermal coals. Virtually no thought is given as to how the coal performs or how much is used. Consequently, it is not uncommon for cheap, low quality coals to be purchased, even though it is not the choice that will result in the lowest power generation cost when all other factors are taken into consideration. The author has developed a model which allows to differentiate between coals for a range of properties relative to the use of the coal, so that a coal company can calculate the break-even price in term of cost per kWh of electricity generated and enable a more valid cost comparison between coals to be made

  15. Rapid fuel switching from coal to natural gas through effective carbon pricing

    Great Britain's overall carbon emissions fell by 6% in 2016, due to cleaner electricity production. This was not due to a surge in low-carbon nuclear or renewable sources; instead it was the much-overlooked impact of fuel switching from coal to natural gas generation. This Perspective considers the enabling conditions in Great Britain and the potential for rapid fuel switching in other coal-reliant countries. We find that spare generation and fuel supply-chain capacity must already exist for fuel switching to deliver rapid carbon savings, and to avoid further high-carbon infrastructure lock-in. More important is the political will to alter the marketplace and incentivize this switch, for example, through a stable and strong carbon price. With the right incentives, fuel switching in the power sector could rapidly achieve on the order of 1 GtCO2 saving per year worldwide (3% of global emissions), buying precious time to slow the growth in cumulative carbon emissions.

  16. A long-term view of worldwide fossil fuel prices

    2010-01-01

    This paper reviews a long-term trend of worldwide fossil fuel prices in the future by introducing a new method to forecast oil, natural gas and coal prices. The first section of this study analyses the global fossil fuel market and the historical trend of real and nominal fossil fuel prices from 1950 to 2008. Historical fossil fuel price analysis shows that coal prices are decreasing, while natural gas prices are increasing. The second section reviews previously available price modelling techniques and proposes a new comprehensive version of the long-term trend reverting jump and dip diffusion model. The third section uses the new model to forecast fossil fuel prices in nominal and real terms from 2009 to 2018. The new model follows the extrapolation of the historical sinusoidal trend of nominal and real fossil fuel prices. The historical trends show an increase in nominal/real oil and natural gas prices plus nominal coal prices, as well as a decrease in real coal prices. Furthermore, the new model forecasts that oil, natural gas and coal will stay in jump for the next couple of years and after that they will revert back to the long-term trend until 2018. (author)

    change in new vehicle purchases toward more diesel vehicles and more fuel-efficient vehicles. The paper analyses to what extent a vehicle tax reform similar to the Danish 2007 reform may explain changes in purchasing behaviour. The paper investigates the effects of a tax reform, fuel price changes......, and technological development on vehicle type choice using a mixed logit model. The model allows a simulation of the effect of car price changes that resemble those induced by the tax reform. This effect is compared to the effects of fuel price changes and technology improvements. The simulations show...... that the effect of the tax reform on fuel efficiency is similar to the effect of rising fuel prices while the effect of technological development is much larger. The conclusion is that while the tax reform appeared in the same year as a large increase in fuel efficiency, it seems likely that it only explains...

    The paper surveyed the preparation of the coal transportation infrastructure, status of its running, economical efficiency, etc. in terms mainly of the trend of coal production/consumption in China, and coal railroad/water transportation and electric power transportation by mine-mouth power generation. From the survey, the following conclusions were obtained. As to the coal which China uses as a main energy for maintaining the present high economic growth as targeted, there will remain the coal transportation problem between production site (north and west) and consumption site (east and south) still in the future (in 2000 and 2010). China is now facing with a big turning point in a socioeconomic aspect. The advancing opening market policy brought steep rises in energy prices such as coal and electric power, which is affecting various fields. Further, the energy related laws, which were unprepared, are abruptly being prepared, and the environment for the introduction of foreign investment, which is expected to be accelerated, is being prepared. In the future, attention should be paid to environmental problems such as air pollution, acid rain and global warming. 48 figs., 96 tabs.

  20. Coal -94

    1994-05-01

    This report deals with use of coal and coke during 1993; information about techniques, environmental questions and markets are also given. Use of steamcoal for heating purposes has been reduced about 3 % during 1993 to 1,0 mill tons. This is the case especially for the heat generating boilers. Production in co-generation plants has been constant and has increased for electricity production. Minor plants have increased their use of forest fuels, LPG and NG. Use of steamcoal will probably go down in the immediate years both in heat generating and co-generating plants. Coal-based electricity has been imported from Denmark during 1993 corresponding to about 400 000 tons of coal, when several of our nuclear plants were stopped. Use of steamcoal in the industry has been constant at 700 000 tons. This level is supposed to be constant or to vary with business cycles. The import of metallurgical coal in 1993 was 1,6 mill tons like the year before. 1,2 mill tons coke were produced. Coke consumption in industry was 1,4 mill tons. 0,2 mill tons of coke were imported. Average price of steamcoal imported to Sweden in 1993 was 308 SEK/ton or 13 % higher than in 1992; this can be explained by the dollar price level increasing 34% in 1993. For the world, the average import price was 50,0 USD/ton, a decrease of 6 %. The coal market during 1993 was affected by less consumption in Europe, shut downs of European mines and decreasing prices. High freight price raises in Russia has affected the Russian export and the market in northern Europe. The prices have been stabilized recently. All Swedish plants meet emission limits of dust, SO 2 and NO x . Co-generation plants all have some sort of SO 2 -removal system; the wet-dry method is mostly used. A positive effect of the recently introduced NO x -duties is a 40% reduction

  1. Update of China economy and coal market

    International Nuclear Information System (INIS)

    Suen, H.

    2010-01-01

    This presentation discussed the surge in China's coal imports. The depressed demand for coal worldwide made huge tonnages available for the Chinese to buy at the same time that there was a willingness to sell coal more cheaply to compete with the Chinese domestic supply price and a coal shortage in China resulting from mine closures and consolidations. The Chinese Government is seeking to slow economic growth to control inflation and prevent an overheated economy. The government emphasis is on energy saving and emission reduction, production cuts at high energy consuming plants, the closure of outdated steel mills, and a restriction on power production. Steel production is expected to fall in the second half of the year as a result of surpluses. China's coal imports will increase in 2010; however, the consolidation process is now completed, and the new capacity will begin to be released in the second half of the year, ending the domestic coal shortage. The increase in the domestic market is constraining price increases. Premium hard coking coal (HCC) remains tight, but normal grade coals are in surplus and facing pressure to reduce prices. China's domestic coal prices form the bottom for the world coal market. Chinese import demand will continue, but demand is expected to gradually decline and be lower in 2011 as the domestic supply becomes sufficient. Nevertheless, China will always have a tremendous demand for coal and needs to import premium HCC. China adopted a quarterly price for the first time this year. 5 tabs., 4 figs.

    Full Text Available in accordance with the article, 11 deposits coal on the territory of Tuva are accounted by State Reserves Register of the Russian Federation, the total profitable reserves are estimated at 1,12 billion tons whereof 936.6 thousand tons are dealt with as coking coals. The vast majority of explored deposits of coals of the republic are concentrated in the Ulugh-Khem basin, the total projected resources of which exceed 20 bill.t. It is substantiated that coking coal of the Ulugh-Khem basin is the most competitive resource of Tyva Republic. Low ash content, excellent caking index, low sulfur and phosphorus in coking coal of ranks GG and GZh indicate their high quality, according to these characteristics GG, GZh coal ranks take precedence over Kuznetsk and Pechora coals. About 70 bill.t of coking coal are annually mined in Russia, but there is a deficit on certain coal ranks. It is primarily related to internal prices increase for coking coal in Russia. According to forecasts of researchers coal deficit will rise up to 15–17 bill.t in the country.

    The United Mine Workers' Union claims that Australia is not getting enough for its coal. Moreover, coal company executives argue that the open market policy was failing the industry and that the export customers were manipulating Australian producers. Consequently, the unions are calling for Federal Government intervention and support the establishment of a national coal authority to co-ordinate the marketing of coal and investment in the industry. ills

    2001-02-01

    A collection of essays were presented to address the issue of rising oil and gas prices. This issue has significant social and environmental implications and the public wants to know what is driving prices up and who is profiting. The myth that gas taxes are driving price increases was dispelled. It was argued that price hikes are mainly due to crude oil price increases and to refining and marketing price increases. The link between rising prices and free trade was also emphasized. The North American Free Trade Agreement (NAFTA) tied Canada into a North American energy market in which U.S. demand sets prices in Canada. It was suggested that trade rules regarding energy should be changed. Other short and longer-term progressive policy alternatives were also presented in the second part of this report. One possible short-term policy response would be to tax windfall oil and gas profits and direct the resulting revenues to rebates for low-income households and for energy conservation initiatives. It was noted that the environmental benefit of rising prices is that it encourages conservation and improved fuel efficiency. The final part of this report discussed the issue of protecting electricity from deregulation and sited lessons learned from the deregulation of natural gas. 2 tabs., 4 figs

    China's coal and electricity industries have a strong reliance on each other, however, because of excessive invasion of government, it is difficult for these two industries to form a stable, reasonable, and transaction cost-saving relationships, but long-run disputes and quarrels. This paper discusses the pricing policies and transaction relationship between these two industries from the historical perspective. It begins with the discussion of coal. Coal market has become competitive since 1980 due to the system of dual track approach, but coal sold to electricity was still tightly controlled by government-guided pricing. Then the paper examines electricity investment and tariff reform. Unlike coal, entry to electricity generation sector was gradually relaxed but generation and retailing tariffs are still strictly regulated. As energy demand and prices soared after 2002, coal and electricity enterprises are all unsatisfied with the rule of price setting of coal sold to electricity industry. This paper concludes that the deliberate low coal price policy does protect electricity industry from fuel cost fluctuation but harm coal industry. Allocative and productive efficiency are difficult to achieve in the long run

  7. U.S. regulators reject proposal to subsidize nuclear and coal power prices

    Kraemer, Jay R.

    2018-01-01

    On January 8, 2018, the U.S. Federal Energy Regulatory Commission (''FERC'') unanimously rejected a rulemaking proposed by Secretary of Energy Rick Perry designed to enable the owners of coal and nuclear power plants to charge higher prices for their output, and thereby to prevent further premature retirements of such plants. The FERC has exclusive authority, under the Federal Power Act, to establish rules for interstate wholesale sales of electricity. Although the FERC simultaneously initiated a new proceeding to consider how to enhance the resilience of electricity supply and delivery in the U.S., that proceeding seems unlikely to offer near-term relief to nuclear plants that are approaching closure due to their inability to compete economically both with facilities fueled by low-priced natural gas and with renewable power sources benefitting from favorable tax provisions. Accordingly, the American nuclear power industry will probably have to look elsewhere for relief from its present dire economic circumstances.

    After enduring contract price cuts over the past two years of almost 17% for thermal coal and 23% for hard coking coal, the New South Wales coal industry is looking forward to a reversal of fortune for 2001. Increased export demand, improved prices, significant improvements in mine site productivity, a weak Australian dollar and the probability of a number of new projects or extensions progressing to development are likely to result in an increase in NSW saleable production to around 110 million tonnes (Mt) in 2000-01. Sharply weaker coal prices over the past two years, intensified international competition and the Asian economic downturn had a negative impact on profitability, investment, exports and employment in the NSW coal industry. As a result, the industry has undergone substantial restructuring. The restructuring process has led to a consolidation in ownership, reduced production costs and improved operational efficiency. The outcome is an industry well positioned to take advantage of the positive market conditions and one likely to experience levels of profitability not achieved over the past few years

  10. Evaluation of risk strategy and market efficiency in the International coal market: A case study of the Japanese coking coal market

    International Nuclear Information System (INIS)

    Wang, T.

    1992-01-01

    Market efficiency and buyers' risk strategy in the Japanese coking import market are examined. The Japanese coal market is found to be inefficient. Japanese buyers traditionally have purchased coals from the United States at a high price and, since the second half of the 1980's, have paid the highest average price to Canadian producers. Given the abundant low cost Australian coals, this purchasing pattern does not meet the cost minimization criteria for efficiency. This is explained mainly by the buyers' risk management strategy. To more accurately examine price differentiation, the complexity of coal quality is considered first. A statistical method is used to estimate comparison of supply regions and a detailed investigation on market conduct is based on quality-adjusted prices, which are assumed to represent the prices of homogeneous coals. Although various reasons are used by researchers to explain Japanese buyers power, this study finds vertical integration of the Japanese companies to be the most important factor creating that power. A detailed survey of vertical integration is made. Finally, a monetary value of the risk premium is estimated by using the partial elasticity of substitution. Total payments by Japanese coking coal buyers for risk premiums are estimated. These represent the extra dollars paid by the Japanese to US and Canadian coal producers for purchasing their coals instead of Australian coals

    2012-07-01

    The author analyses the decision to abandon the co called ''review clause'' (which was the right to revisit the decision to close German hard coal mines in 2012), and thus management flexibility on the basis of the option price theory and use of hedging instruments (derivatives) in coal trading. Only the case of coal production without any subsidies will be taken into account. The original intention of the review clause to subsidise coal production for further years will be left aside. Abandonment of the review clause destroyed a value of the real option of approx. 819 Mio. EUR. It should be agreed with the politicians that the decision concerning potential extension of coal production without subsidies should be made at the end of 2015. At this point in time the coal price for 2019 to 2021 can be locked in by forward contracts. A prerequisite for coal mining without subsidies would be an increase in the coal price of 3.1% p.a., which is only slightly above the inflation rate and seems to be realistic against the background of rising oil prices and increased scarcity of natural resources.

    Wood Mackenzie operates coal consulting offices in several cities around the world and is the number one consulting company in terms of global coal coverage. The company offers a unique mine-by-mine research methodology, and owns a proprietary modeling system for coal and power market forecasting. This presentation provided an overview of global thermal markets as well as recent market trends. Seaborne markets have an impact on price far greater than the volume of trade would imply. Research has also demonstrated that the global thermal coal market is divided between the Pacific and Atlantic Basins. The current status of several major coal exporting countries such as Canada, the United States, Venezuela, Colombia, Indonesia, Australia, China, South Africa, and Russia was displayed in an illustration. The presentation included several graphs indicating that the seaborne thermal coal market is highly concentrated; traditional coal flow and pricing trends shift as Asian demand growth and supply constraints lead to chronic under supply; coal prices have risen to historic highs in recent times; and, the Asian power sector demand is a major driver of future growth. The correlation between oil and gas markets to thermal coal was illustrated along with two scenarios of coal use in the United States in a carbon-constrained world. The impact of carbon legislation on coal demand from selected coal regions in the United States was also discussed. Wood Mackenzie forecasts a very strong growth in global thermal coal demand, driven largely by emerging Asian economies. tabs., figs

    Continually rising energy prices in global markets highlights a serious concern about the need to improve energy efficiency and the efficiency in energy sector in many countries. China, as one of the fastest growing countries in the world and the largest coal producer, has high coal consumption but a low recovery rate of coal utilization. Coal efficiency and the efficiency in coal industry have therefore attracted a great deal of attention from Chinese policy makers, coal firms and academics. This study attempts to compare the relative technical efficiency performance of listed coal mining companies in China and the US using CCR and BCC models in the advanced DEA linear programming. The results show that the level of relative efficiency in Chinese coal mining enterprises, regardless of total technical efficiency or decomposed pure technical and scale efficiency, is much lower than in American coal firms. The study also highlights the input resources that cause the inefficiency of Chinese coal mining companies. Furthermore, in-depth discussion and analysis of how the institutional environments of the two countries could cause the differences are provided. (author)

    Purpose The high cost of oncology drugs threatens the affordability of cancer care. Previous research identified drivers of price growth of targeted oral anticancer medications (TOAMs) in private insurance plans and projected the impact of closing the coverage gap in Medicare Part D in 2020. This study examined trends in TOAM prices and patient out-of-pocket (OOP) payments in Medicare Part D and estimated the actual effects on patient OOP payments of partial filling of the coverage gap by 2012. Methods Using SEER linked to Medicare Part D, 2007 to 2012, we identified patients who take TOAMs via National Drug Codes in Part D claims. We calculated total drug costs (prices) and OOP payments per patient per month and compared their rates of inflation with general health care prices. Results The study cohort included 42,111 patients who received TOAMs between 2007 and 2012. Although the general prescription drug consumer price index grew at 3% per year over 2007 to 2012, mean TOAM prices increased by nearly 12% per year, reaching $7,719 per patient per month in 2012. Prices increased over time for newly and previously launched TOAMs. Mean patient OOP payments dropped by 4% per year over the study period, with a 40% drop among patients with a high financial burden in 2011, when the coverage gap began to close. Conclusion Rising TOAM prices threaten the financial relief patients have begun to experience under closure of the coverage gap in Medicare Part D. Policymakers should explore methods of harnessing the surge of novel TOAMs to increase price competition for Medicare beneficiaries.

  18. Protection of the German coal industry

    1989-06-01

    Within Germany, subsidies to the domestic coal industry are raising taxes, increasing electricity prices, constraining industry competitiveness and causing distortions to resource allocation decisions. Coal assistance policies raise the costs of German industry, particularly those which use coal and electricity. In the case of assistance to steaming coal production, subsidies are less explicit, making the direct cost of continued support to the industry less obvious. If Germany deregulated its coal industry, it would become a major coal importer, conceivably importing as much as 60 Mt a year. Such an increase in import demand would raise world coal trade volume significantly. The impact of liberalisation on world coal prices would depend on the extent and timing of liberalisation and the responsiveness of suppliers to the increased import demand. 13 refs., 5 figs., 2 tabs.

    The report deals mainly with coal consumption, but also gives some information about technology, environmental aspects and markets. Data have been collected by questionnaires or via telephone. The use of steam coal for heating was 0.8 Mtons (down 20% from 1994). Cogeneration plants were the main users. Taxes and environmental reasons cause a reduction of the coal use that will probably continue the next years. Use of steam coal in industry has been constant at a level of 0.7 Mtons. The import of metallurgical coal rests constant at a level of 1.6 Mtons. 1.2 Mtons of coke was produced, and 0.3 Mtons imported. The PFBC-plant at Vaertan, Stockholm used 0.13 Mtons of coal, while some coal fired power plants have been converted to peat and wood fuels. The average price of steam coal imported to Sweden in 1995 was 333 SEK/ton, 6% higher than in 1994. The contract prices for delivery 1996 are about the same as at the end of 1995. All cogeneration plants have some sort of SO 2 removal system, mostly wet-dry. The largest plant, at Vaesteraas, has recently invested in a SCR system for NO x removal. Most other plants are using low NO x burners or SNCR systems, based on ammonia or urea, which reduce the emissions 50 - 70%. Some statistic about the world coal market is also given in the report

    Surveys were conducted of the trends of coal companies in the U.S. and Australia and of the lookout for new coal field development in Australia for the purpose of contributing to the stable supply of coal in the future. In the U.S., the coal industry has experienced serious changes in these ten years, and various corporations, such as Peabody, Arch Coal, CONSOL, and Kennecott have come to resort to drastic measures for their survival. In Australia, coal price is lower and contract terms are shorter with less demand for coal supply thanks to the economic crisis in Asia. As for demand for coal in Asia, on the other hand, it is deemed that in 2010 there will be a 41% increase over the 1995 level and that, therefore, coal field preservation and new field exploitation are necessary. Since production by strip mining in New South Wales State is to decrease in 2012 and after, it is expected that new projects will start only after 2012. Comprehensive development projects are going to be launched in the areas surrounding the Surat district, Queensland State, and therefore new projects will be easier to start in this region. Since the Surat coal is to be collected after a little stripping, it is expected that it will be able to compete with the Indonesian coal. (NEDO)

  1. The logic of the primary energy prices evolution

    1992-01-01

    This paper deals, very briefly, with the basis factors determining the prices levels of the primary energies and the logic of their evolution both in the short and in the long term. It first gives definitions: of the limits of mineral commodities prices fluctuations and of the long term equilibrium prices. Then, it tries to demonstrate three points: (1) Coal and nuclear electricity prices are driven in the long term only by their own production and environmental costs. Moreover, coal prices fluctuations are surrounded by factors which are basically independent from oil prices. (2) There is no such thing as one single equilibrium price for oil, but several ones, depending on political factors, and among them, on the degree of consensus between the 'Five' of the Gulf (Saudi Arabia, Iran, Irak, Koweit, The Emirates). (3) Natural gas prices are in an intermediate situation, but tend to get closer to the case of coal and nuclear prices. 4 figs

    Situated at the intersection of the literatures on speculative storage and non-renewable commodity scarcity, this paper considers whether changes in persistence have occurred in long-run U.S. prices of the energy commodities crude oil, natural gas and bituminous coal. We allow for a structural break when testing for a break in persistence to avoid a change in the stochastic properties of prices being confounded by an unaccounted-for deterministic shift in the price series. We find that coal prices are trend stationary throughout their evolution and that oil prices change from stationarity to non-stationarity in the decade between the late 1960s to late 1970s. The result on gas prices is ambiguous. Our results demonstrate the importance of accounting for a possible structural shift when testing for breaks in persistence, while being robust to the exact date of the structural break. Based on our analysis we caution against viewing long-run energy commodity prices as being non-stationary and conclude in favor of modeling commodity market fundamentals as stationary, meaning that speculative storage will tend to have a dampening effect on prices. We also cannot reject that long-run prices of coal and, with some hesitation, gas follow a Hotelling-type rule. In contrast, we reject the Hotelling rule for oil prices since the late 1960s/early 1970s. - Highlights: • This paper contributes to the literatures on speculative storage and scarcity. • We test if long-run U.S. coal, oil and gas prices became non-stationary. • We pre-test for structural breaks when testing for changes in persistence. • Coal prices are found to be trend stationary, oil prices become non-stationary. • We caution against modeling commodity market fundamentals as non-stationary.

    2005-11-15

    In 2003 the May/June issue of CoalTrans International speculated that coal liquefaction would become viable due to falling coal prices. This has not proved the case but the sustained high oil price is sparking new interest. A survey by Energy Intelligence and Marketing Research during November 2005 revealed a growth in the number of projects under development or at the feasibility stage. The article reports projects in China, the USA, Australia, New Zealand, the Philippines and India. China is commissioning the first wave of large liquefaction plants. The key question is whether other countries, particularly the USA, will follow.

  8. Estimating the shadow prices of SO2 and NOx for U.S. coal power plants: A convex nonparametric least squares approach

    Mekaroonreung, Maethee; Johnson, Andrew L.

    2012-01-01

    Weak disposability between outputs and pollutants, defined as a simultaneous proportional reduction of both outputs and pollutants, assumes that pollutants are byproducts of the output generation process and that a firm can “freely dispose” of both by scaling down production levels, leaving some inputs idle. Based on the production axioms of monotonicity, convexity and weak disposability, we formulate a convex nonparametric least squares (CNLS) quadratic optimization problem to estimate a frontier production function assuming either a deterministic disturbance term consisting only of inefficiency, or a composite disturbance term composed of both inefficiency and noise. The suggested methodology extends the stochastic semi-nonparametric envelopment of data (StoNED) described in Kuosmanen and Kortelainen (2011). Applying the method to estimate the shadow prices of SO 2 and NO x generated by U.S. coal power plants, we conclude that the weak disposability StoNED method provides more consistent estimates of market prices. - Highlights: ► Develops methodology to estimate shadow prices for SO 2 and NO x in the U.S. coal power plants. ► Extends CNLS and StoNED methods to include the weak disposability assumption. ► Estimates the range of SO 2 and NO x shadow prices as 201–343 $/ton and 409–1352 $/ton. ► StoNED method provides more accurate estimates of shadow prices than deterministic frontier.

  9. Historical costs of coal-fired electricity and implications for the future

    2011-01-01

    We study the cost of coal-fired electricity in the United States between 1882 and 2006 by decomposing it in terms of the price of coal, transportation cost, energy density, thermal efficiency, plant construction cost, interest rate, capacity factor, and operations and maintenance cost. The dominant determinants of cost have been the price of coal and plant construction cost. The price of coal appears to fluctuate more or less randomly while the construction cost follows long-term trends, decreasing from 1902 to 1970, increasing from 1970 to 1990, and leveling off since then. Our analysis emphasizes the importance of using long time series and comparing electricity generation technologies using decomposed total costs, rather than costs of single components like capital. By taking this approach we find that the history of coal-fired electricity suggests there is a fluctuating floor to its future costs, which is determined by coal prices. Even if construction costs resumed a decreasing trend, the cost of coal-based electricity would drop for a while but eventually be determined by the price of coal, which fluctuates while showing no long-term trend. - Research highlights: → 125-year history highlights the dominant determinants of coal-fired electricity costs. → Results suggest a fluctuating floor to future costs, determined by coal prices. → Analysis emphasizes importance of comparing technologies using decomposed total costs.

    Describes the low technological state of Yugoslav coal enterprises,in particular of those that exploit low grade lignite and brown coal with high ash and sulfur content. Unadjusted coal prices (almost the same price level for low and high energy coal) and absence of stringent laws on environmental pollution are regarded as main reasons for the low technological level of coal preparation and beneficiation plants. Modern preparation equipment for coal classification, coal washing, coal drying and briquetting is pointed out. Advanced coal carbonization and gasification should have a wider application in Yugoslavia for reducing environmental pollution and producing clean fuel.

    Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

  14. The resilience of the Indian economy to rising oil prices as a validation test for a global energy-environment-economy CGE model

    2008-09-01

    This paper proposes to test the global hybrid computable general equilibrium model IMACLIM-R against macro-economic data. To do so, it compares the modeled and observed responses of the Indian economy to the rise of oil price during the 2003-2006 period. The objective is twofold: first, to disentangle the various mechanisms and policies at play in India's economy response to rising oil prices and, second, to validate our model as a tool capable of reproducing short-run statistical data. With default parametrization, the model predicts a significant decrease in the Indian growth rate that is not observed. However, this discrepancy is corrected if three additional mechanisms identified by the International Monetary Fund are introduced, namely the rise in exports of refined oil products, the imbalance of the trade balance allowed by large capital inflows, and the incomplete pass-through of the oil price increase to Indian customers. This work is a first step toward model validation, and provides interesting insights on the modeling methodology relevant to represent an economy's response to a shock, as well as on how short-term mechanisms - and policy action - can smooth the negative impacts of energy price shocks or climate policies.

    Gray, D.; Tomlinson, G.

    1995-01-01

    The paper discusses the global energy demand situation as presented at the last World Energy Congress. The total energy demand was calculated for each country and projected to 2100. The paper then discusses the energy situation in the United States, especially the forecasted demand for crude oil and natural gas liquids. Imports will be needed to make up the shortfall in domestic production. The shortfall in conventional petroleum could be supplied by converting coal into liquid fuels. Currently the cost of high quality coal liquids is too high to compete with petroleum, but trends suggest that the price will be competitive in the year 2030 using current technology. Continuing research on coal liquefaction will reduce the price of coal liquids so that coal liquids could play a significant role sooner

    In recent years, prices of coal and crude oil have fallen significantly. These declines have had a large impact on China’s energy-economy-environment system variables. This paper establishes a computable general equilibrium model to systematically analyse the impact of coal price changes alone...... or the decline of both coal and oil prices on the variables of China's energy-economy-environment system. The results of the analysis show that the decline of the coal price alone or of coal and crude oil prices together will lead to a significant increase in demand for either coal and total energy or coal...

    Beck, R.J.

    1998-01-01

    Capital spending by oil and gas companies in and outside the US will rise in 1998, but that forecast may be jeopardized by the continuing plunge in oil prices. For operations in the US, oil and gas company capital spending is expected to move up in 1998 for the fourth year in a row. If the money is spent, it will be the highest industry investment level since 1985. Strong oil and gas prices and increased volumes have boosted company cash flow and profits the last few years, fueling increased spending. However, the near-term outlook has now been clouded by economic turmoil in a number of Asian countries and the recent collapse of oil prices. The paper discusses oil and gas prices, US upstream spending, US non-exploration and production spending, capital spending in Canada, and spending outside US and Canada

    A critique of the Tennessee Valley Authority (TVA) review of competition in the two industries reviews several versions and updates of the report and compares them with the Wilson report. The authors find inconsistencies and errors in TVA's arguments and evidence. They argue that the reports do not demonstrate a cause and effect relationship between oil company entry into coal and uranium markets and rising prices and concentration. Instead the reports merely assert such a relationship, then use their assertion as the sole basis for policy recommendations. 1 figure, 6 tables

  20. Prospects and technical and economic evaluation of methods for obtaining synthetic liquid from coal

    Energy Technology Data Exchange (ETDEWEB)

    Shlikhter, E B; Khor' kov, A V; Zhorov, Y M

    1980-11-01

    Rising oil prices and the exhaustion of cheap organic fuels point to the need for chemical processing of coal to obtain synthetic liquid fuels. Added importance for such development in the USSR is dictated by the remote location of many coal deposits, such as the Kansko-Achinsk basin. Methods for synthesizing described include thermal dissolution in a hydrogen donor solvent, hydrogenation, and gasification with subsequent synthesis and pyrolysis. The need for improved technology is stressed. Cost factors are related to the chemical process involved, rather than to losses in fuel quantities, and the methanol produced is readily transported by pipeline. It can be used for both gasoline and diesel fuels.

  1. Modelling the impact of oil prices on Vietnam's stock prices

    Narayan, Paresh Kumar; Narayan, Seema

    2010-01-01

    The goal of this paper is to model the impact of oil prices on Vietnam's stock prices. We use daily data for the period 2000-2008 and include the nominal exchange rate as an additional determinant of stock prices. We find that stock prices, oil prices and nominal exchange rates are cointegrated, and oil prices have a positive and statistically significant impact on stock prices. This result is inconsistent with theoretical expectations. The growth of the Vietnamese stock market was accompanied by rising oil prices. However, the boom of the stock market was marked by increasing foreign portfolio investment inflows which are estimated to have doubled from US$0.9 billion in 2005 to US$1.9 billion in 2006. There was also a change in preferences from holding foreign currencies and domestic bank deposits to stocks local market participants, and there was a rise in leveraged investment in stock as well as investments on behalf of relatives living abroad. It seems that the impact of these internal and domestic factors were more dominant than the oil price rise on the Vietnamese stock market. (author)

  2. Problems of coal-based power generation

    International Nuclear Information System (INIS)

    Noskievic, P.

    1996-01-01

    Current problems of and future trends in coal-based power generation are discussed. The present situation is as follows: coal, oil and gas contribute to world fossil fuel resources 75%, 14%, and 11%, respectively, and if the current trend will continue, will be depleted in 240, 50, and 60 years, respectively; the maximum resource estimates (including resources that have not yet been discovered) are 50% higher for oil and 100% higher for gas, for coal such estimates have not been made. While the world prices of coal are expected to remain virtually constant, the prices of gas will probably increase to be twice as high in 2010. Thus, the role of coal may be higher in the next century than it is now, provided that due attention is paid to improving the efficiency of coal-fired power plants and reducing their adverse environmental effects. A comparison of economic data for coal-fired and gas-fired power plants is as follows: Investment cost (USD/kW): 1400, 800; fixed running cost (USD/kW.y): 33.67, 9.0; variable running cost (USD/kWh): 0.30, 0.15; power use (kJ/kWh): 10.29, 7.91; annual availability (%): 70, 50; fuel price (USD/GJ): 1.00, 4.30; power price (USD/kWh): 4.28, 5.52. The investment cost for coal-fired plants covers new construction including flue gas purification. The integrated gasification combined cycle (IGCC) seems to be the future of coal-based power generation. The future problems to be addressed include ways to reduce air pollution, improving the efficiency of the gas-steam cycle, and improving the combustion process particularly with a view to reducing substantially its environmental impact.

    In the run up to the privatisation of the electricity supply industry in Scotland, the South of Scotland Electricity Board (SSEB) is involved in a battle for power with British Coal's Scottish area over the price of its coal, the bulk of which has been purchased by the SSEB in recent years. The SSEB has been trying to persuade British Coal to bring its prices down to those currently available on the world market. This would require a reduction of some 30%. The SSEB has backed up its requests by threatening to import more foreign coal if British Coal refuses to comply.

International coal trading continues to grow and the tendency may persist in the mext two years

  5. Coal and gas competition in global markets

    Energy Technology Data Exchange (ETDEWEB)

    2013-07-01

    Global consumption of commercial energy totalled 18 Gt of coal equivalent in 2010. With a 28% share, coal ranked second after oil as one of the major sources of primary energy and natural gas (at 21%) ranked third. Gross power generation with coal was approximately 41% and gas 22%. Natural gas as a global commodity is growing rapidly with the advent of unconventional sources such as shale gas. Recently, gas has become the fuel of choice for new power generating plants in some countries. Overall production of coal has increased in the same time-frame. The share of coal in electricity production was constant in Europe from early 2000 but recently increased. This was due to the high cost of gas in Europe and a low emissions penalty levied by the regulator, making coal currently more competitive in Europe compared to gas. Coal utilisation continues to increase in Asia but is facing serious competition with gas in the USA, where the share of electricity generated with coal dropped in 2012. However, natural gas used to generate electricity in early 2013 was below the high level seen during the comparable 2012 period, when low natural gas prices led to significant displacement of coal by natural gas for power generation. The current consensus in the USA is that while coal may recover ground in the short term, it loses in the long term as coal plants are retired. The discovery, production and availability of significant amounts of gas have implications for not only the price of natural gas but also the price of coal as well as supply and demand, and utilisation of both fuels internationally. The interaction between coal and gas in the global markets today is investigated in this review and the near-term outlook and impact on both fuels is presented. In this report, reserves, production and trade, supply and demand, pricing, utilisation and consumption, public attitudes and finally near/short to medium-term prospects are discussed for both coal and gas.

    The paper examines the long-run relation and short-run dynamics between electricity prices and three fossil fuel prices - coal, natural gas and crude oil - using annual data for the U.S. for 1960-2007. The results suggest (1) a stable long-run relation between real prices for electricity and coal (2) Bi-directional long-run causality between coal and electricity prices. (3) Insignificant long-run relations between electricity and crude oil and/or natural gas prices. And (4) no evidence of asymmetries in the adjustment of electricity prices to deviations from equilibrium. A number of implications are addressed. (author)

    2017-01-01

    China's energy prices have long been regulated due to the critical role energy plays in economic growth and social development, which leads to energy-price distortion to some extent. To figure out whether energy-price regulations will benefit China's economy (measured by GDP growth) and environment (measured by carbon emissions), we conducted an in-depth simulation using path analysis, where five energy products (natural gas, gasoline, fuel oil, steam coal, and coking coal) are selected and three measurements (absolute, relative, and moving) of energy-price distortions are calculated. The results indicate that, with a series of energy pricing policies, the price distortion for a single type of energy has gradually transformed, while the energy pricing system in China is not fully market-oriented yet. Furthermore, China's economy benefits from relative and moving distortions, while the absolute distortions of energy prices have negative impacts on economic growth. Finally, with regard to the environment, carbon emissions call for fewer distortions. - Highlights: • Price distortion for a single type of energy has gradually transformed. • Energy pricing system in China is not yet fully market-oriented. • China's economy benefits from relative and moving distortions. • Absolute distortions of energy prices have negative effects on economic growth. • Carbon emissions call for less pricing distortions.

Costs required Webster/Hazelton to go back to the old, reliable alternative energy of low Btu gasification when the natural gas supply started to be curtailed and prices escalated. Although anthracite coal prices have skyrocketed from $34/ton (1979) to over $71.50/ton (1981) because of high demand (local as well as export) and rising labor costs, the delivered natural gas cost, which reached $3.90 to 4.20/million Btu in the Hazelton area during 1981, has allowed the producer gas from the gasifier at Webster Brick to remain competitive. The low Btu gas cost (at the escalated coal price) is estimated to be $4/million Btu. In addition to producing gas that is cost competitive with natural gas at the Webster Brick Hazelton plant, Webster has the security of knowing that its gas supply will be constant. Improvements in brick business and projected deregulation of the natural gas price may yield additional, attractive cost benefits to Webster Brick through the use of low Btu gas from these gasifiers. Also, use of hot raw gas (that requires no tar or sulfur removal) keeps the overall process efficiency high. 25 references, 47 figures, 14 tables.

    The topics are presented which were discussed at the 36th Canadian Coal Conference, held in Vancouver, BC in September 1985. The theme was Challenges, today and tomorrow and the conference sought to examine the primary problems confronting the world coal industry today: overcapacity, soft demand, depressed prices and intense global competition. Coal production in Canada was presented and its role in the steelmaking and electric power industries evaluated. A general mood of optimism prevailed.

  13. U.S. origin coking coal in the global market : a seismic shift in the global coal market

    2010-01-01

    This presentation discussed conditions in the global coal market and its impact on producers in the United States (U.S). The significant factors include the strong recovery in Asia, the switch from annual benchmark pricing to quarterly pricing, and the return of U.S. origin coking coal as a long-term supply source for Asia. The global recovery in manufacturing is strong in Asia and weak in more mature economies. A shift in trade patterns has occurred in that 4 of the top 10 destinations for U.S. coking coal exports are now in Asia, up from 1 in 2009, and the tonnage increases to these destinations are at unprecedented levels. Demand for U.S. origin coal will continue to increase as the economies in Western Europe improve and the emerging economies in Eastern Europe and South America grow. Looking at the U.S. coking coal supply, high volume type A coal will be used in the domestic market while high volume type B coal will be used for international demand. Government regulatory agencies create an uncertain environment for investments. Geology and the effects of regulatory actions have decreased productivity. An improvement to the supply chain is that lower cost ocean freight lowers the cost of delivered coal. The prices of coking coal have stabilized at levels that support reasonable returns on investment. The seaborne coking coal market has changed with China's shift to being a significant importer. Mine, rail, and port capacity will constrain the ability of producers in the U.S. to export coking coal to some degree. 2 tabs., 13 figs.

  15. Why investors shy away from coal

    Why do investors shy away from coal? This may sound like a strange question given the change in ownership of many major coal companies in recent years, but the ongoing consolidation within the coal industry is quite different from any actual new investment in the industry. To begin to understand why, one must return to the early '70s, a time of low-cost, abundant energy. The price of oil was about $2-4/bbl until 1973. The price of natural gas was about 60 cents/M ft 3 , and coal was approximately $7/st. This, however, was before the first Organization of the Petroleum Exporting Countries (OPEC) shock. The price of coal declined throughout the 1980s, and continues its downward path in some markets. Many coal investments have not achieved their expected return, such as the case of a 1M st/yr mine in West Virginia, which was developed in the early '80s only to be put immediately on a care-and-maintenance basis, where it languished until it was sold in 1990. Other mines, such as the large open-pit mines in the Powder River Basin in Wyoming, never reached their targeted production rates. Some of these large mines had equipment that remained in crates for years, only later to be sold at a loss. The extent of losses on investments in coal mines is discussed

    With crude oil prices rocketing, many of the oil poor, but coal rich countries are looking at coal-to-liquid as an alternative fuel stock. The article outlines the two main types of coal liquefaction technology: direct coal liquefaction and indirect coal liquefaction. The latter may form part of a co-production (or 'poly-generation') project, being developed in conjunction with IGCC generation projects, plus the production of other chemical feedstocks and hydrogen. The main part of the article, based on a 'survey by Energy Intelligence and Marketing Research' reviews coal-to-liquids projects in progress in the following countries: Australia, China, India, New Zealand, the Philippines, Qatar and the US. 2 photos.

    Australian mine production is recovering from massive flooding while Canadian coal shipments are limited by mine and rail capacity. Polish, Czech, and Russian coking coal shipments have been reduced and United States coking coal shipments are reaching their maximum capacity. On the demand side, the Chinese government has increased export taxes on metallurgical coal, coking coal, and thermal coal. Customers seem to be purchasing in waves and steel prices are declining. This presentation addressed the global outlook for coal as well as the challenges ahead in terms of supply and demand. Supply challenges include regulatory uncertainty; environmental permitting; labor; and geology of remaining reserves. Demand challenges include global economic uncertainty; foreign exchange values; the effect of customers making direct investments in mining operations; and freight rates. Consolidation of the coal industry continued and several examples were provided. The presentation also discussed other topics such as coking coal production issues; delayed mining permits and environmental issues; coking coal contract negotiations; and stock values of coking coal producers in the United States. It was concluded that consolidation will continue throughout the natural resource sector. tabs., figs

    Because of a growing global energy demand and rising oil prices coal-abundant nations, such as China and the United States, are pursuing the application of technologies which could replace crude oil imports by converting coal to synthetic hydrocarbon fuels-so-called coal-to-liquids (CtL) technologies. The case of CtL is well suited to analyse techno-economic, resources-related, policy-driven and actor-related parameters, which are affecting the market prospects of a technology that eases energy security constraints but is hardly compatible with a progressive climate policy. This paper concentrates on Germany as an example-the European Union (EU)'s largest member state with considerable coal reserves. It shows that in Germany and the EU, CtL is facing rather unfavourable market conditions as high costs and ambitious climate targets offset its energy security advantage

    The goal of this paper is to model the impact of oil prices on Vietnam's stock prices. We use daily data for the period 2000-2008 and include the nominal exchange rate as an additional determinant of stock prices. We find that stock prices, oil prices and nominal exchange rates are cointegrated, and oil prices have a positive and statistically significant impact on stock prices. This result is inconsistent with theoretical expectations. The growth of the Vietnamese stock market was accompanied by rising oil prices. However, the boom of the stock market was marked by increasing foreign portfolio investment inflows which are estimated to have doubled from US$0.9 billion in 2005 to US$1.9 billion in 2006. There was also a change in preferences from holding foreign currencies and domestic bank deposits to stocks local market participants, and there was a rise in leveraged investment in stock as well as investments on behalf of relatives living abroad. It seems that the impact of these internal and domestic factors were more dominant than the oil price rise on the Vietnamese stock market. (author)

    This paper reviews the US's coal trade with other countries in the world. Despite being pressed to support domestic coal producers, US utilities are looking towards Colombia for more of their supplies. Whilst the amount of Colombian coal imported into the US is small, it is a combination of this and coal imported from Australia, Canada and China which is causing concern. Studies indicate that the volume of coal imported into the US may rise to 3 Mt/year within three years. Coal exports may suffer if Brazil bans the import of significant quantities of US coking coal in retaliation against American trade sanctions against Brazilian computer import barriers. Also, Romania is expected to impose tariffs on US imports which will have an impact on US coal exported to Romania. US remains the top coal exporter to the European Communities but its lead was cut back due to a big rise of Australian export. A portion of EC market has also been lost to the USSR and Poland. Meanwhile, Japan is resisting buying US's steam coal because it is too expensive.

    This report documents the objectives and the conceptual and methodological approach used in the development of the National Energy Modeling System`s (NEMS) Coal Market Module (CMM) used to develop the Annual Energy Outlook 1998 (AEO98). This report catalogues and describes the assumptions, methodology, estimation techniques, and source code of CMM`s two submodules. These are the Coal Production Submodule (CPS) and the Coal Distribution Submodule (CDS). CMM provides annual forecasts of prices, production, and consumption of coal for NEMS. In general, the CDS integrates the supply inputs from the CPS to satisfy demands for coal from exogenous demand models. The international area of the CDS forecasts annual world coal trade flows from major supply to major demand regions and provides annual forecasts of US coal exports for input to NEMS. Specifically, the CDS receives minemouth prices produced by the CPS, demand and other exogenous inputs from other NEMS components, and provides delivered coal prices and quantities to the NEMS economic sectors and regions.

  4. The evolution of hard coal trade in the Pacific market

    2006-01-01

    This article analyses the evolution of hard coal trade in the Asia Pacific region, known as the Pacific market, from the 1980s to the present years. It investigates the development of the trade pattern, the nature of contracts, the price setting, the supply demand and the future of trade. Over the last two decades, the international trade in the Pacific market has achieved dramatic increases in coal commerce. This achievement is due to strong demand in Japan and North-east Asian countries and progressive coal export in Australia and Indonesia. It is likely that this market will continue to expand and become a more important market in replacing the Atlantic market. In this market, historically, long-term supply contracts were usual and concluded between producer and consumer. Even recently, there are still annual contracts, but with a small number of deals. In contrast, spot transactions are now becoming more important. Previously, Japan had been influential in price setting by establishing 'a benchmark price' with Australian coal suppliers. Afterward 'a reference price' was becoming a trend. Nowadays, spot price indices, such as the Barlow Jonker, the Barlow Jonker ACR and globalCOAL, have become important to set the price. The Pacific market growth is not without problems. The exporter countries, particularly Australia and Indonesia, have some challenges that if they are not resolved at present, it would implicate the performance of the coal trade

    In recent years, there has been a convergence of international trade with traditional domestic markets. With imports increasing in many coal-producing regions, the influence of trade on domestic markets has been twofold: firstly, imported coal displaces domestic production, and in doing so, and secondly international price trends may drive prices of what remains of the indigenous market for coal.

    Energi, Haesselbyverket, has now invested in equipment for burning pellets instead of coal. In Linkoeping wastes of rubber are mixed with coal. Also Soederenergi AB has rebuilt their three coal boilers and replaced 100 % of the coal by peat and wood fuels. Coal is a reserve fuel. Several co-generation plants like Linkoeping, Norrkoeping, Uppsala and Oerebro use both coal and forest fuels. The use of coal is then concentrated to the electricity production. The average price of steam coal imported in Sweden in 1997 was 370 SEK/ton or 10 per cent higher than in 1996. For the world, the average import price fell to 46 USD/ton. The price fall was concentrated to the 4th quarter. The prices have continued to fall during 1998 as a result of the crisis in Asia. All Swedish plants meet their emission limits of dust, SO 2 and NO x given by county administrations or concession boards. The co-generation plants have all some sort of SO 2 -removal system. Mostly used is the wet-dry method. The biggest co-generation plant, Vaesteraas, has newly invested in a ca talytic NO x -cleaning system type SCR, which is reducing the emission level 80-90 %. Most other plants are using low NO x -burners or injection systems type SNCR, based on ammonium or urea, which are reducing the emissions 50-70 %. A positive effect of the recently introduced NO x -duties is a 60 % reduction compared to some years ago, when the duties were introduced. World hard coal production was about 3 800 tons in 1997, a minor increase compared to 1996. The coal demand in the OECD-countries has increased about 1.7 % yearly during the last ten years. The coal share of the energy supply is about 20% in the OECD-countries and 27% in the whole world. Several sources estimate a continuing growth during the next 20 years in spite of an increasing use of natural gas and nuclear power. The reason is a strong demand for electrical power in the Asian countries and the developing countries. However, greater efforts to minimize the

    China has been, is, and will continue to be a coal-powered economy. The rapid growth of coal demand since 2001 has created deepening strains and bottlenecks that raise questions about supply security. Although China's coal is 'plentiful,' published academic and policy analyses indicate that peak production will likely occur between 2016 and 2029. Given the current economic growth trajectory, domestic production constraints will lead to a coal gap that is not likely to be filled with imports. Urbanization, heavy industry growth, and increasing per-capita consumption are the primary drivers of rising coal usage. In 2006, the power sector, iron and steel, and cement accounted for 71% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units could save only 14% of projected 2025 coal demand. If China follows Japan, steel production would peak by 2015; cement is likely to follow a similar trajectory. A fourth wedge of future coal consumption is likely to come from the burgeoning coal-liquefaction and chemicals industries. New demand from coal-to-liquids and coal-to-chemicals may add 450 million tonnes of coal demand by 2025. Efficient growth among these drivers indicates that China's annual coal demand will reach 4.2 to 4.7 billion tonnes by 2025. Central government support for nuclear and renewable energy has not been able to reduce China's growing dependence on coal for primary energy. Few substitution options exist: offsetting one year of recent coal demand growth would require over 107 billion cubic meters of natural gas, 48 GW of nuclear, or 86 GW of hydropower capacity. While these alternatives will continue to grow, the scale of development using existing technologies will be insufficient to substitute significant coal demand before 2025. The central role of heavy industry in GDP growth and the difficulty of substituting other fuels suggest that coal consumption is

    In this paper, we present a review of the deregulation of energy prices in China between 1985 and 2004 and assess the impacts of changes in energy prices on aggregate energy intensity and coal/oil/electricity intensity. We used time series data to provide estimates of energy price elasticities. Empirical results showed that: (1) The own-price elasticities of coal, oil, and aggregate energy were negative in periods both before and after 1995, implying that higher relative prices of different energy types lead to the decrease in coal, oil, and aggregate energy intensities. However, the positive own-price elasticity of electricity after 1995 probably indicates that the price effect was weaker than other factors such as income effect and population effect. (2) The impacts of energy prices were asymmetric over time. (3) Sectoral adjustment also drove the decrease in aggregate energy intensity. Although raising energy prices to boost efficiency of energy use seems to be an effective policy tool, other policy implications concerned with energy prices, such as energy supply security and fuel poverty, must also be considered

  11. Price changes in the gasoline market: Are Midwestern gasoline prices downward sticky?

    International Nuclear Information System (INIS)

    1999-03-01

    This report examines a recurring question about gasoline markets: why, especially in times of high price volatility, do retail gasoline prices seem to rise quickly but fall back more slowly? Do gasoline prices actually rise faster than they fall, or does this just appear to be the case because people tend to pay more attention to prices when they're rising? This question is more complex than it might appear to be initially, and it has been addressed by numerous analysts in government, academia and industry. The question is very important, because perceived problems with retail gasoline pricing have been used in arguments for government regulation of prices. The phenomenon of prices at different market levels tending to move differently relative to each other depending on direction is known as price asymmetry. This report summarizes the previous work on gasoline price asymmetry and provides a method for testing for asymmetry in a wide variety of situations. The major finding of this paper is that there is some amount of asymmetry and pattern asymmetry, especially at the retail level, in the Midwestern states that are the focus of the analysis. Nevertheless, both the amount asymmetry and pattern asymmetry are relatively small. In addition, much of the pattern asymmetry detected in this and previous studies could be a statistical artifact caused by the time lags between price changes at different points in the gasoline distribution system. In other words, retail gasoline prices do sometimes rise faster than they fall, but this is largely a lagged market response to an upward shock in the underlying wholesale gasoline or crude oil prices, followed by a return toward the previous baseline. After consistent time lags are factored out, most apparent asymmetry disappears

    Coal world production represents 3.5 billions of tons, plus 900 millions of tons of lignite. 50% of coal is used for power generation, 16% by steel making industry, 5% by cement plants, and 29% for space heating and by other industries like carbo-chemistry. Coal reserves are enormous, about 1000 billions of tons (i.e. 250 years of consumption with the present day rate) but their exploitation will be in competition with less costly and less polluting energy sources. This documents treats of all aspects of coal: origin, composition, calorific value, classification, resources, reserves, production, international trade, sectoral consumption, cost, retail price, safety aspects of coal mining, environmental impacts (solid and gaseous effluents), different technologies of coal-fired power plants and their relative efficiency, alternative solutions for the recovery of coal energy (fuel cells, liquefaction).

    Coal consumption is growing up so fast and coal reserves are so abundant that coal might overtake petroleum in the future. The worldwide environment will not gain anything in this evolution except if 'clean coal' technologies make a significant jump. What is the driving force of this coal development? The pitfall encountered by nuclear energy and the rise of natural gas prices have been favorable conditions for the development of coal but they cannot hide the worldwide metamorphosis of coal industry. From China, undisputed world leader, to the USA, without omitting India, Russia and the big exporting countries (Australia, Indonesia, South Africa, Colombia), a new map is drawing up. In all these countries, coal companies are concentrating and internationalizing, open new strip mines and new commercial paths.

    Our main message is that it is optimal to use less coal and more oil once one takes account of coal being a backstop which emits much more CO2 than oil. The way of achieving this is to have a steeply rising carbon tax during the initial oil-only phase, a less-steeply rising carbon tax during the intermediate phase where oil and coal are used alongside each other and the following coal-only phase, and a flat carbon tax during the final renewables-only phase.

The direct reason for this is the soaring price of coal, which has reached a height not attained in a quarter of a century. Like crude oil in countries such as China, it is expected to be short in supply and short in demand for some time coming. While many look to the development of new energy mechanisms such as solar energy panels and wind turbines, the increase in extreme weather brought about by changes in the global climate sheds doubt on the effectiveness of these methods. In the 21st century, as we witness great changes in our global environment and energy utilization, the advantages of nuclear power generation in terms of costs, global warming measures, and resource conservation are being increasingly recognized. Now is the time to capitalize on these advantages. Responsible explanations about the safety of nuclear power are needed in order to restore the people's trust in this resource. Meanwhile, we should push forward with those projects that have clearly demonstrated their safe utilization of nuclear reactor technologies. (author)

    A recent NEA study entitled Carbon Pricing, Power Markets and the Competitiveness of Nuclear Energy assesses the competitiveness of nuclear power against coal- and gas-fired power generation in liberalised electricity markets with either CO 2 trading or carbon taxes. It uses daily price data for electricity, gas, coal and carbon from 2005 to 2010, which encompasses the first years of the European Emissions Trading System (EU ETS), the world's foremost carbon trading framework. The study shows that even with modest carbon pricing, competition for new investment in electricity markets will take place between nuclear energy and gas-fired power generation, with coal-fired power struggling to be profitable. The data and analyses contained in the study provide a robust framework for assessing cost and investment issues in liberalised electricity markets with carbon pricing, even in the post-Fukushima context. A summary of the publication main elements is provided in this paper

    Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

  3. Coal resources availability in Botswana

    1990-01-01

    This paper reports that Southern Africa, and Botswana in particular, is well-endowed with relatively large reserves of coal. The existence of coal in Botswana has been known since the end of the last century. Exploration activities by the Geological Survey and the private sector led to the discovery of major deposits and by the late 1960s reserves capable of supporting a mine at Morupule for the domestic market has been confirmed. The oil crises of 1973-74 and 1978-79 stimulated increased interest in coal exploration the world over and Botswana attracted several private sector companies looking for coal that could be traded on the international market. As a result vast resources and reserves of low to medium quality bituminous coal, suitable for the export market, were proved. Resources amounting to 21,680 million tonnes of in situ coal had been revealed by 1987. Reserves of possible economic exploitation are estimated at 10,180 million tonnes in two coal field areas, namely the Morupule Coal Field and the Mmamabula Coal Field. Since the collapse of oil prices and consequently coal prices in the mid-1980s, enthusiasm for coal exploration has plummeted and relatively little prospecting has taken place. The coal occurs within the Upper Carboniferous to Jurassic Karoo Supergroup which underlies some 60 percent of the country's land surface. The western part of the country is mantled by the Kalahari beds, a top layer of unconsolidated sands masking bedrock geology. Although coal seams have been intersected in boreholes in this western area, most exploration activity has taken place in the eastern part of the country where the Morupule and Mmamabula coal fields are located. It is in the east that most of the population is concentrated and infrastructure has been developed

    Coal is and will remain the world's most abundant and widely distributed fossil fuel. Burning coal, however, can pollute and it produces carbon dioxide. Clean coal technologies address this problem. The widespread deployment of pollution-control equipment to reduce sulphur dioxide, Nox and dust emissions from industry is just one example which has brought cleaner air to many countries. Since the 1970s, various policy and regulatory measures have created a growing commercial market for these clean coal technologies, with the result that costs have fallen and performance has improved. More recently, the need to tackle rising CO2 emissions to address climate change means that clean coal technologies now extend to include those for CO2 capture and storage (CCS). This short report from the IEA Coal Industry Advisory Board (CIAB) presents industry's considered recommendations on how to accelerate the development and deployment of this important group of new technologies and to grasp their very signifi cant potential to reduce emissions from coal use. It identifies an urgent need to make progress with demonstration projects and prove the potential of CCS through government-industry partnerships. Its commercialisation depends upon a clear legal and regulatory framework,public acceptance and market-based financial incentives. For the latter, the CIAB favours cap-and-trade systems, price supports and mandatory feed-in tariffs, as well as inclusion of CCS in the Kyoto Protocol's Clean Development Mechanism to create demand in developing economies where coal use is growing most rapidly. This report offers a unique insight into the thinking of an industry that recognises both the threats and growing opportunities for coal in a carbon constrained world.

    Coal-fired power plants enjoy a significant advantage relative to gas plants in terms of cheaper fuel cost. This advantage may erode (or turn into disadvantage) depending on CO 2 emission allowance price. Financial risks are further reinforced when the price of electricity is determined by natural gas-fired plants' marginal costs. We aim to empirically assess the risks in EU coal plants' margins up to the year 2020. Parameter values are derived from actual market data. Monte Carlo simulation allows compute the expected value and risk profile of coal plants' earnings. Future allowance prices may spell significant risks on utilities' balance sheets. (author)

    Our main message is that it is optimal to use less coal and more oil once one takes account of coal being a backstop which emits much more CO2 than oil. The way of achieving this is to have a steeply rising carbon tax during the initial oil-only phase, a less-steeply rising carbon tax during the

  8. Market-driven energy pricing necessary to ensure China's power supply

    2009-01-01

    China's rapid economic growth has strained its power supply, as manifested for instance by the widespread 2008 power shortage. The cause for this shortage is thought to be the current Chinese energy pricing system, which is mainly government rather than market controlled. Government-regulated price-caps for coal have seriously affected coal supply. At the same time price-caps for electricity supply have caused suspension of power plant operation. As a result, the average operating time of coal-fired power plants declined 50 h annually across the nation in the first half of 2008 compared to the previous year, despite clear power shortages. Here, it will be suggested that energy pricing, set by supply and demand may effectively discourage excessive growth in heavy industry, substantially encourage energy conservation and efficiency, and curb the rapid electricity demand in China. It will be argued that a market-oriented electricity pricing mechanism is required for China to secure its future power supply. (author)

  11. Coal in competition

    1985-06-01

    During the past decade world coal consumption has expanded by about 26% whilst energy demands overall have grown by only 17%. This is because of the increased price of oil products, plus a period during which the costs of mining coal in many parts of the world have been moderately well contained. Over-ambitious forecasts of coal demand have encouraged the considerable over-investment in coalmining capacity that exists today. Costs of winning coal and transporting it are low, but sales depend on the rate of growth of a country's demand for energy. Some countries are more successful at marketing coal than others. Amongst the major factors that influence the rate of substitution of one source of energy for another is the nature and age of the boiler stock. The outcome of the developing environmental debate and calls for reduction in SO/sub 2/ and NO/sub x/ emissions from coal-fired boilers is going to affect coal's fortunes in the 1990's.

    Full Text Available This study analyzes factors affecting the price of South Korea’s Certified Emission Reduction (CER using statistical methods. CER refers to the transaction price for the amount of carbon emitted. Analysis of results found a co-integration relationship among the price of South Korea’s CER, oil price (WTI, and South Korea’s maximum electric power demand, which means that there is a long-term relationship among the three variables. Based on this result, VECM (vector error correction model analysis, impulse response function, and variance decomposition were performed. As the oil price (WTI increases, the demand for gas in power generation in Korea declines while the demand for coal increases. This leads to increased greenhouse gas (GHG; e.g., CO2 emissions and increased price of South Korea’s CERs. In addition, rising oil prices (WTI cause a decline in demand for oil products such as kerosene, which results in an increase in South Korea’s maximum power demand.

  13. E-commerce and the coal industry

    Industry observers currently peg the share of 'spot' contracts in Australia's black coal export market (valued at $9 billion a year) at 15%, compared with only 5% of market share four years ago. This quantum shift in purchasing habits is being driven largely by abundant coal supplies, a multi-source availability of coal, and falling prices - a scenario that is expected to remain unchanged for at least the next three to five years. Contracts are not only becoming shorter, they are also dealing with lower tonnages. And, unlike under older long term contracts, where prices are reset every one to two years, under the modern versions prices are being reset every three to six months. As buyers push to achieve more competitive pricing outcomes and maximise the supply of competitively priced fuel, this forces everyone associated with operating power plants to look for ways to reduce costs and implement higher levels of efficiency, by saving time and paperwork. Net-based trading in coal is happening. The major buyers and sellers operate most of the existing sites. Buyers see the Net as a means of reducing the cost of their fuel; sellers see it as a means of better displaying the product they offer. The use of the Net is seen as providing improved market intelligence, greater transparency, better marketing and service levels and enhanced efficiencies. The one-to-one approach remains a fixture and its future is assured. However, whether the Net will ultimately support independent trading sites similar to those whose income will come from brokering deals is hard to judge.

    2015-12-01

    We examined whether sales of new motorcycles was a mechanism to explain the relationship between motorcycle fatalities and gasoline prices. The data came from the Motorcycle Industry Council, Energy Information Administration and Fatality Analysis Reporting System for 1984-2009. Autoregressive integrated moving average (ARIMA) regressions estimated the effect of inflation-adjusted gasoline price on motorcycle sales and logistic regressions estimated odds ratios (ORs) between new and old motorcycle fatalities when gasoline prices increase. New motorcycle sales were positively correlated with gasoline prices (r = 0.78) and new motorcycle fatalities (r = 0.92). ARIMA analysis estimated that a US$1 increase in gasoline prices would result in 295,000 new motorcycle sales and, consequently, 233 new motorcycle fatalities. Compared to crashes on older motorcycle models, those on new motorcycles were more likely to be young riders, occur in the afternoon, in clear weather, with a large engine displacement, and without alcohol involvement. Riders on new motorcycles were more likely to be in fatal crashes relative to older motorcycles (OR 1.14, 95 % confidence interval (CI) 1.02-1.28) when gasoline prices increase. Our findings suggest that, in response to increasing gasoline prices, people tend to purchase new motorcycles, and this is accompanied with significantly increased crash risk. There are several policy mechanisms that can be used to lower the risk of motorcycle crash injuries through the mechanism of gas prices and motorcycle sales such as raising awareness of motorcycling risks, enhancing licensing and testing requirements, limiting motorcycle power-to-weight ratios for inexperienced riders, and developing mandatory training programs for new riders.

    China's modern coal chemical industry has grown into a certain scale after over a decade of development, and remarkable progress has been made in key technologies. But as oil price collapsed since 2015, the economic benefit of the industry also slumped, with loud controversies in China over the necessity of modern coal chemical industry. The research believes that the modern coal chemical industry plays a positive role in the clean and sustainable exploitation of coal in China. It makes profit when oil price is no lower than 60/bbl, and outperforms petrochemical in terms of cost effectiveness when the price is between 60/bbl and 80/bbl. Given the low oil price and challenges posed by environmental protection and water restraints, we suggest that the state announce a guideline quickly, with adjusted tax policies and an encouragement to technological innovation, so that the modern coal chemical industry in China can grow sound and stable.

    With the current known oil reserves of about 11 billion barrel and annual production of approximately 500 million barrel, the country's oil reserves will be depleted by 2010, and Indonesia would have become net oil importer if no major oil fields be found somewhere in the archipelago. Under such circumstances the development of new sources of liquid fuel becomes a must, and coal liquefaction can be one possible solution for the future energy problem in Indonesia, particularly in the transportation sector due to the availability of coal in huge amount. This paper present the prospect of coal liquefaction in Indonesia and look at the possibility of integrating the process with HTR as a heat supplier. Evaluation of liquidability of several low grade Indonesian coals will also be presented. Coal from South Banko-Tanjung Enim is found to be one of the most suitable coal for liquefaction. Several studies show that an advanced coal liquefaction technology recently developed has the potential to reduce not only the environmental impact but also the production cost. The price of oil produced in the year 2000 is expected to reach US $ 17.5 ∼ 19.2/barrel and this will compete with the current oil price. Not much conclusion can be drawn from the idea of integrating HTR with coal liquefaction plant due to limited information available. (author). 7 figs, 3 tabs

It indicates as coal can be mined from the Delbi reserve at a cost of EB110/tonne, can be processed for EB400/tonne and transported to Addis Ababa for 150/tonne. The wholesale price of coal briquettes in Addis Ababa would be EB750/tonne. Domestic users can save EB475 per year by switching from charcoal to coal briquettes. And for a 50MW plant annual saving would be of the order of EB30 million per year. 11 tab. 4 figs. 6 appendex

    While present interest in coal-fired power generation is centred on the developing countries, with new natural-gas-fired power stations predominating in the developed world, in the long term coal will return to being the fuel of choice for power generation for much of the world. To minimise the global impact of coal use it is essential, therefore, that coal technologies are developed that are efficient, clean and economically attractive. Techno-economic analyses of the options for coal are presented together with a strategic overview of potential lines of development. The broad conclusions are that new coal plants will not be truly competitive with natural gas until the price of gas increases to about 3.3 EURO/GJ, compared with a coal price of 1.3 EURO/GJ. Present state-of-the-art pulverised coal-fired plant is close to its optimum techno-economic performance and further improvements depend on the development of cost-effective super-alloys. However, there are good opportunities to increase the efficiency of coal use to greater than 50% (LHV basis) using gasification-based power generation cycles. Unless credit is given for the much lower emissions provided by these cycles, the pulverised coal and pressurised fluidised bed combustion will remain the most economic options. (author)

    1970-01-01

    The creation of new markets by making oil fuels from coal in Britain is unresolved at this time. The dominant factor in the economics is the price ratio between coal and oil, which in Britain is 3 times less favorable than in the U.S. Current conversion results in a price more than double that of natural oil; however, the National Coal Board (NCB) continues to assess oil-from-coal processes. A sound research background in the new field of coal derivatives from solvent processing is being developed to produce materials of higher specific value than fuels. A continuous pilot plant is being built to prepare coke from filtered coal solution on the scale of a half-a-ton per week. Future prospects of the industry lie in areas where markets for coal will diminish, such as metallurgical coke. The fate of the coal industry will depend more and more on its largest market-electricity generation. In order to compete with nuclear power, the NCB is developing a new system of fluidized combustion.

    Carbon costs - either in the form of a carbon tax or through permit prices in an emissions trading scheme - would ultimately be reflected in higher electricity prices. Carbon cost ''pass-through'' is critical to the survival of existing coal generation assets and has been discussed widely as a measure of business impact in the electricity industry. This paper sets out in a structured way the factors that determine price pass-through and why this may differ greatly across different systems. Although the basic concept of price pass-through is simple, a clear understanding of the underlying factors is critical to developing insights on how carbon cost would impact on existing coal generation businesses. It is shown that pass-through can vary drastically if the underlying dispatch potential of generators varies significantly across alternative emissions reduction scenarios. It can also vary depending on the availability of competing cleaner forms of generation. Pass-through as a measure of business performance is, therefore, hard to generalize across different circumstances and should be interpreted carefully. (author)

  8. Environmental costs resulting from the use of hard coal to electricity generation in Poland

    In the world's fuel mix used for generating electricity, the most common fossil fuel is coal. In the EU, coal combustion and electricity generation entail the need to purchase emission allowances (EUA) whose purchase costs affect the costs of electricity generation significantly. The research described in the article shows how current market conditions shape the profitability of generating electricity from coal and how Clean Dark Spread (CDS) changes as a function of changes in energy and coal prices at the assumed levels of emission and prices of EUA allowances. The article compares the results of CDS calculations in two variants. Areas have been highlighted where prices of both coal and EUA allowances cause CDS to assume values at which the prices of generated electricity do not cover the costs of fuel (i) and CO2 emission allowances, cover all costs (ii), or constitute positive prices (iii), but still do not cover all fixed costs. With higher power plant efficiency, CO2 emissions are lower (0.722 t/MWh). The costs of purchasing fuel required to generate 1 MWh of electricity are also lower. In such case—even with relatively high prices of coal—a power plant can achieve profitability of electricity generation.

    Full Text Available In the world's fuel mix used for generating electricity, the most common fossil fuel is coal. In the EU, coal combustion and electricity generation entail the need to purchase emission allowances (EUA whose purchase costs affect the costs of electricity generation significantly. The research described in the article shows how current market conditions shape the profitability of generating electricity from coal and how Clean Dark Spread (CDS changes as a function of changes in energy and coal prices at the assumed levels of emission and prices of EUA allowances. The article compares the results of CDS calculations in two variants. Areas have been highlighted where prices of both coal and EUA allowances cause CDS to assume values at which the prices of generated electricity do not cover the costs of fuel (i and CO2 emission allowances, cover all costs (ii, or constitute positive prices (iii, but still do not cover all fixed costs. With higher power plant efficiency, CO2 emissions are lower (0.722 t/MWh. The costs of purchasing fuel required to generate 1 MWh of electricity are also lower. In such case—even with relatively high prices of coal—a power plant can achieve profitability of electricity generation.

  10. Energy prices and substitution in United States manufacturing plants

    Grim, Cheryl

    Persistent regional disparities in electricity prices, growth in wholesale power markets, and recent deregulation attempts have intensified interest in the performance of the U.S. electric power industry, while skyrocketing fuel prices have brought renewed interest in the effect of changes in prices of all energy types on the U.S. economy. This dissertation examines energy prices and substitution between energy types in U.S. manufacturing. I use a newly constructed database that includes information on purchased electricity and electricity expenditures for more than 48,000 plants per year and additional data on the utilities that supply electricity to study the distribution of electricity prices paid by U.S. manufacturing plants from 1963 to 2000. I find a large compression in the dispersion of electricity prices from 1963 to 1978 due primarily to a decrease in quantity discounts for large electricity purchasers. I also find that spatial dispersion in retail electricity prices among states, counties and utility service territories is large, rises over time for smaller purchasers, and does not diminish as wholesale power markets expand in the 1990s. In addition, I examine energy type consumption patterns, prices, and substitution in U.S. manufacturing plants. I develop a plant-level dataset for 1998 with data on consumption and expenditures on energy and non-energy production inputs, output, and other plant characteristics. I find energy type consumption patterns vary widely across manufacturing plants. Further, I find a large amount of dispersion across plants in the prices paid for electricity, oil, natural gas, and coal. These high levels of dispersion are accounted for by the plant's location, industry, and purchase quantity. Finally, I present estimates of own- and cross-price elasticities of demand for both the energy and non-energy production inputs.

    This Department of Energy National Energy Technology Laboratory sponsored project developed carbon products, using mildly hydrogenated solvents to extract the organic portion of coal to create synthetic pitches, cokes, carbon foam and carbon fibers. The focus of this effort was on development of lower cost solvents, milder hydrogenation conditions and improved yield in order to enable practical production of these products. This technology is needed because of the long-term decline in production of domestic feedstocks such as petroleum pitch and coal tar pitch. Currently, carbon products represents a market of roughly 5 million tons domestically, and 19 million tons worldwide. Carbon products are mainly derived from feedstocks such as petroleum pitch and coal tar pitch. The domestic supply of petroleum pitch is declining because of the rising price of liquid fuels, which has caused US refineries to maximize liquid fuel production. As a consequence, the long term trend has a decline in production of petroleum pitch over the past 20 years. The production of coal tar pitch, as in the case of petroleum pitch, has likewise declined significantly over the past two decades. Coal tar pitch is a byproduct of metallurgical grade coke (metcoke) production. In this industry, modern metcoke facilities are recycling coal tar as fuel in order to enhance energy efficiency and minimize environmental emissions. Metcoke production itself is dependent upon the production requirements for domestic steel. Hence, several metcoke ovens have been decommissioned over the past two decades and have not been replaced. As a consequence sources of coal tar are being taken off line and are not being replaced. The long-term trend is a reduction in coal tar pitch production. Thus import of feedstocks, mainly from Eastern Europe and China, is on the rise despite the relatively large transportation cost. To reverse this trend, a new process for producing carbon products is needed. The process must be

    Multiple economic and geologic factors are driving fundamental changes in the nation’s energy system, weakening coal’s dominance as a fuel for electricity generation, with significant implications for places like West Virginia that are heavily dependent on coal for economic activity. Some of these factors include low natural gas prices, rising labor costs and declining productivity, economic competition with other coal mining regions, environmental regulations to reduce pollution and safeguard public health, state energy efficiency and renewable electricity standards, falling costs of renewable energy resources like wind and solar, and the likely prospect of future limits on greenhouse gas emissions. This analysis uses an input–output model to examine the effects on West Virginia’s economy from these multiple factors by exploring a range of scenarios for coal production through 2020. In addition to changes in the coal industry, hypothetical investments in additional sectors of the economy are considered as a way to gauge potential alternative economic opportunities. This paper offers recommendations to policymakers for alternative economic development strategies needed to create new jobs and diversify the state’s economy, and highlights the importance of transition assistance at the federal level.

    The United States` competitive position in world markets will be determined by many forces. Two of the fundamental factors are the increased use of new technologies, and the availability of low-cost electricity to operate those technologies. The US currently has an will likely continue to have market dominance in both these critical areas. Both of these factors are intimately related since the primary source of new technologies is electric in nature. And, because low-cost coal now dominates and will continue to dominate the electric supply system, and because the US has both an abundance of coal and the world`s largest fleet of coal-fired power plants, the US will have an expanding base of low-cost electricity that will secure its current competitive advantage for years to come. Electric technologies and, increasingly, computer-based technologies integrated with electric technologies are the primary sources of innovative advancement and economic growth. As a consequence, the growth in electricity, which has historically tracked GNP growth, is expected to continue. And, with the restructuring of the electric utility industry and the emergence of vigorous competition, prices are expected to decline as competition increases. The net effect of these forces will be to dramatically increase the use of electric technologies -- and those sources of electricity that can provide low-cost electricity. The data show that coal, the primary source of new los-cost electricity, will supply between one-half and three-fourths of all new electric supply through 2010, at prices of about 3{cents}/kWh, and can do so without new power plant construction. Since the use of coal is expected to rise by at least 200 to 250 million tons/year over the current consumption of 850 million tons, and could increase as much as 400 million tons/yr, some have raised concerns about the emissions impact from the power plants. This report also shows that the net effect of increased electric use, assuming

    Coal is and will remain the world’s most abundant and widely distributed fossil fuel. Burning coal, however, can pollute and it produces carbon dioxide. Clean coal technologies address this problem. The widespread deployment of pollution-control equipment to reduce sulphur dioxide, Nox and dust emissions from industry is just one example which has brought cleaner air to many countries. Since the 1970s, various policy and regulatory measures have created a growing commercial market for these clean coal technologies, with the result that costs have fallen and performance has improved. More recently, the need to tackle rising CO2 emissions to address climate change means that clean coal technologies now extend to include those for CO2 capture and storage (CCS). This short report from the IEA Coal Industry Advisory Board (CIAB) presents industry’s considered recommendations on how to accelerate the development and deployment of this important group of new technologies and to grasp their very signifi cant potential to reduce emissions from coal use. It identifies an urgent need to make progress with demonstration projects and prove the potential of CCS through government-industry partnerships. Its commercialisation depends upon a clear legal and regulatory framework,public acceptance and market-based financial incentives. For the latter, the CIAB favours cap-and-trade systems, price supports and mandatory feed-in tariffs, as well as inclusion of CCS in the Kyoto Protocol’s Clean Development Mechanism to create demand in developing economies where coal use is growing most rapidly. This report offers a unique insight into the thinking of an industry that recognises both the threats and growing opportunities for coal in a carbonconstrained world.

    2003-01-01

    Alberta power pool prices for year 2000 were reviewed. The model assumptions were: studies based on PROSYM market simulations; base-load units offered at incremental cost; and, considerations in those cases where system gas units were modeled as coal units. The current situation in Alberta was reviewed. The Genesee 3 coal-fired facility is expected to be completed in the Winter 2004-2005 with an efficiency of 8 to 18 per cent better than other coal units. A graph was shown to examine the expected impact of Genesee 3 on Alberta prices. Electricity prices would increase during the period 2005-2008 without Genesee 3. Alberta prices are affected by factors such as: load-resource balance, fuel prices, cost of new capacity, offer strategy, available transmission, and tie lines. A capacity surplus is expected for the period 2003-2008. In addition, good correlation is expected for pool prices with gas prices. With Genesee 3 in operation, lower pool prices are expected in Alberta. figs

  19. Oil price, biofuels and food supply

    2011-01-01

    The price of oil could play a significant role in influencing the expansion of biofuels, but this issue has yet to be fully investigated in the literature. Using a global computable general equilibrium (CGE) model, this study analyzes the impact of oil price on biofuel expansion, and subsequently, on food supply. The study shows that a 65% increase in oil price in 2020 from the 2009 level would increase the global biofuel penetration to 5.4% in 2020 from 2.4% in 2009. If oil prices rise 150% from their 2009 levels by 2020, the resulting penetration of biofuels would be 9%, which is higher than that would be caused by current mandates and targets introduced in more than forty countries around the world. The study also shows that aggregate agricultural output drops due to an oil price increase, but the drop is small in major biofuel producing countries as the expansion of biofuels would partially offset the negative impacts of the oil price increase on agricultural outputs. An increase in oil price would reduce global food supply through direct impacts as well as through the diversion of food commodities and cropland towards the production of biofuels. - Highlights: ► A global CGE model to analyze impacts of oil price on biofuels and food supply. ► Global biofuel penetration increases from 2.4% (2009) to 5.4% (2020) in baseline. ► A 150% rise of oil price boosts biofuels more than current mandates and targets do. ► Biofuels partially offset drops in agricultural outputs caused by oil price rise. ► Biofuels as well as oil price rise negatively affect global food supply.

    The report deals with base-load electricity generation from coal and compares the economics of four alternative technologies: conventional pulverised-fuel (PF) boiler with steam cycle; atmospheric fluidised-bed (AFB) boiler with steam cycle; pressurised fluidised-bed (PFB) boiler with combined cycle; and integrated air-blown coal gasification with combined cycle systems are compared for both a high sulphur (3.5%) coal with environmental regulations requiring 85% sulphur removal, and for a low sulphur coal without sulphur removal. The results indicate that there is no single clear 'winner' among the advanced technologies. The optimum system depends on coal price, required rate-of-return, sulphur content of the coal, taxation regime etc. (34 refs.) (Available from IEA Coal Research, Economic Assessment Service)

    Rates of child malnutrition and mortality in India remain high. We tested the hypothesis that rising food prices are contributing to India's slow progress in improving childhood survival. Using rounds 2 and 3 (2002-08) of the Indian District Level Household Survey, we calculated neonatal, infant and under-five mortality rates in 364 districts, and merged these with district-level food price data from the National Sample Survey Office. Multivariate models were estimated, stratified into 27 less deprived states and territories and 8 deprived states ('Empowered Action Groups'). Between 2002 and 2008, the real price of food in India rose by 11.7%. A 1% increase in total food prices was associated with a 0.49% increase in neonatal (95% confidence interval (CI): 0.13% to 0.85%), but not infant or under-five mortality rates. Disaggregating by type of food and level of deprivation, in the eight deprived states, we found an elevation in neonatal mortality rates of 0.33% for each 1% increase in the price of meat (95% CI: 0.06% to 0.60%) and 0.10% for a 1% increase in dairy (95% CI: 0.01% to 0.20%). We also detected an adverse association of the price of dairy with infant (b = 0.09%; 95% CI: 0.01% to 0.16%) and under-five mortality rates (b = 0.10%; 95% CI: 0.03% to 0.17%). These associations were not detected in less deprived states and territories. Rising food prices, particularly of high-protein meat and dairy products, were associated with worse child mortality outcomes. These adverse associations were concentrated in the most deprived states. © The Author 2016. Published by Oxford University Press on behalf of the International Epidemiological Association.

  2. Coal fired steam generation for heavy oil recovery

    International Nuclear Information System (INIS)

    Firmin, K.

    1992-01-01

    In Alberta, some 21,000 m 3 /d of heavy oil and bitumen are produced by in-situ recovery methods involving steam injection. The steam generation requirement is met by standardized natural-gas-fired steam generators. While gas is in plentiful supply in Alberta and therefore competitively priced, significant gas price increases could occur in the future. A 1985 study investigating the alternatives to natural gas as a fuel for steam generation concluded that coal was the most economic alternative, as reserves of subbituminous coal are not only abundant in Alberta but also located relatively close to heavy oil and bitumen production areas. The environmental performance of coal is critical to its acceptance as an alternate fuel to natural gas, and proposed steam generator designs which could burn Alberta coal and control emissions satisfactorily are assessed. Considerations for ash removal, sulfur dioxide sorption, nitrogen oxides control, and particulate emission capture are also presented. A multi-stage slagging type of coal-fired combustor has been developed which is suitable for application with oilfield steam generators and is being commissioned for a demonstration project at the Cold Lake deposit. An economic study showed that the use of coal for steam generation in heavy oil in-situ projects in the Peace River and Cold Lake areas would be economic, compared to natural gas, at fuel price projections and design/cost premises for a project timing in the mid-1990s. 7 figs., 3 tabs

  3. The coal question that emissions trading has not answered

    Can emissions trading assist with the task of placing a limit on coal production and consumption in Australia? This paper outlines a critical political economy perspective on coal and a flagship ‘market mechanism’ for emissions reduction. The prospects for an effective emissions trading scheme in coal-dominated economies are considered in light of its theoretical justifications as well as recent attempts to price carbon in Australia. Emissions trading is a weak instrument that does not address real-world failures of coal governance. At their theoretical best, carbon prices produce marginal changes to the cost structure of production. In practice, the Australian case demonstrates emissions trading is an attempt to displace the emissions reduction task away from coal, through compensation arrangements and offsetting. In light of the urgent need to rapidly reduce global emissions, direct regulation and democratisation of coal production and consumption should be flagship climate policy. - Highlights: • Emissions trading schemes (ETS) are weak instruments for placing a limit on coal. • Pre-existing failures of coal governance cannot be addressed by emissions trading. • Considerable transfers of public wealth to coal companies occurred as part of the Australian ETS. • Carbon offset arrangements spatially displace responsibility for reducing emissions away from coal.

    More than 286 million tons of coal exceeds the Phase I standard i.e. 2.5 lb SO 2 per mmBtu, of the US Clean Air Act (1990). 85 mmtpy goes to currently scrubbed or unaffected (i.e. small) units. This leaves 201 mmtpy of high-sulphur coal at risk. 129 mmtpy of this is moving on a spot basis or is shipped under contracts that expire by 1995. This leaves about 72 mmtpy of captive and longterm contracts which many utility fuel buyers assume will be cancelled or renegotiated at a lower price. The legal position remains uncertain. However, the massive cancellation and/or renegotiation of existing contracts will have a tremendous economic impact on the coal industry. The resultant price change will in turn influence decisions to scrub or switch to low sulphur coals. 2 figs., 2 tabs

    Full Text Available Coal prices between 2006-2015 trend was fluctuate but tend to decrease every year and affect regional income, especially South Sumatra Province. Coal prices fluctuation are influenced by several factors, the decline of world oil prices, coal production surplus, and China imports restriction. Coal mining industry also give a direct impact to the environment especially effect to work environment for the company workers and the people environment around mining. The coal mining company absorbs local labor so as to increase local revenues from individual income taxes. This research use quantitative approach using Ordinary Least Square (OLS analytical method with E-views 7 software. Multiple linier regression technique also applied. The Secondary data is time series of 2006 - 2015. The results presented in form of tables, images and narration. From this research can be drawn conclusion that price fluctuations have no effect on regional income, but production sold has an effect on regional income.

    2012-01-01

    The asymmetry of Chinese coal and electricity pricing reforms leads to serious conflict between coal suppliers and electricity utilities. Electricity utilities experience significant losses as a result of conflict: severe coal price fluctuations, and uncertainty in the quantity and quality of coal supplies. This paper explores whether establishing cooperative relationships between coal suppliers and electricity utilities can resolve conflicts. We begin with a discussion of the history of coal and electricity pricing reforms, and then conduct a theoretical analysis of relational contracting to provide a new perspective on the drivers behind the establishment of cooperative relationships between the two parties. Finally, we empirically investigate the role of cooperative relationships and the establishment of mine-mouth power plants on the performance of electricity utilities. The results show that relational contracting between electricity utilities and coal suppliers improves the market performance of electricity utilities; meanwhile, the transportation cost savings derived from mine-mouth power plants are of importance in improving the performance of electricity utilities. - Highlights: ► We discuss the history of coal and electricity pricing reforms. ► The roots of conflicts between electricity and coal firms are presented. ► We conduct a theoretical analysis of relational contracting. ► The role of mine-mouth power plants on the performance of power firms is examined.

    To establish a reasonable system and mechanism for Chinese energy prices, we use the Granger causality test, Hodrick–Prescott (HP) filter and time difference analysis to research the pricing relationship between Chinese and international energy prices. We find that Chinese and international crude oil prices changed synchronously while Chinese refined oil prices follow the changes of international oil prices with the time difference being about 1 month to 2 months. Further, Australian coal prices Granger causes Chinese coal prices, and there is a high correlation between them. The U.S. electricity price is influenced by the WTI crude oil price, the U.S. gasoline price and the HenryHub gas price. Due to the unreasonable price-setting mechanism and regulation from the central government, China′s terminal market prices for both electricity and natural gas do not reflect the real supply–demand situation. This paper provides quantitative results on the correlation between Chinese and international energy prices to better predict the impact of international energy price fluctuations on China′s domestic energy supply and guide the design of more efficient energy pricing policies. Moreover, it provides references for developing countries to improve their energy market systems and trading, and to coordinate domestic and international energy markets. -- Highlights: •The Hodrick-Prescott filter and time difference analysis are used to research the correlation among energy prices. •Our study finds that the U.S. and British refined oil prices Granger cause the Chinese refined oil price. •Both Chinese and the Australian coal prices play an important role in the international coal market. •The Chinese terminal electric power and terminal natural gas prices are not highly correlated. •The results are useful for guiding the design of more efficient energy pricing policies in China

    The concern shown by energy leaders regarding the continuing decline in productivity is not just academic. Rather, it is viewed as a serious threat, not only to the industry but also to the national economy. Recently, a mine operator commented on the productivity decline by saying that the decline does not affect his company because it merely raises the price and then passes the price increase on to the consumer. He felt that, while the mine operator is interested in reducing costs, legislation, labor unrest, and other factors contributing to increased costs are all beyond his control. Although a great many people in the coal industry do not share these views, many do. Therefore, a study of the underlying causes of the decline in productivity is extremely important and is, in essence, truly a national issue. The observation is that as productivity declines, the cost of coal rises proportionally. Obviously the coal industry is in business to make a profit. As conditions change (e.g., more laws are passed, labor unrest increases, and worker attitudes worsen) and resultant productivity declines occur, the costs of coal extraction will increase. Undoubtedly these costs will be passed along to the consumer. The USBM, as a part of an overall effort by the government to solve energy problems, is playing an important role in the coal industry. By identifying the causes of the decline in productivity, it can better direct its efforts in reversing the trend. This can be and is being accomplished by advancing mechanization and developing new technologies in coal mining that better meet the requirements of legislation, improve safety and productivity, and are less sensitive to the impacts of labor unrest, attitudinal shifts, and motivational problems.

    Germany continues to play a pioneering role in replacing conventional power plants with renewable energy sources. While this might be beneficial with respect to environmental quality, it also implies increasing electricity prices. The extent to which this is associated with negative impacts on employment depends on the interrelationship between labor and electricity as input factors in the production process. In this paper, we estimate cross-price elasticities between electricity and heterogeneous labor for the German manufacturing sector. We use administrative linked employer–employee micro-data combined with information on sector-level electricity prices and usage over the period 2003–2007. We find positive, but small conditional cross-price elasticities of labor demand with respect to electricity prices, which means that electricity as an input factor can be replaced by labor to a limited extent when the production level is held constant. In the case of adjustable output, we find negative unconditional cross-price elasticities, implying that higher electricity prices lead to output reductions and to lower labor demand, with low- and high-skilled workers being affected more than medium-skilled. Resulting adverse distributional effects and potential overall job losses may pose challenges for policy-makers in securing public support for the German energy turnaround. - Highlights: • We estimate cross-price elasticities for electricity and labor in manufacturing. • We use linked employer–employee micro-data from Germany for 2003 to 2007. • We find a weak substitutability between electricity and labor for constant output. • We find complementarity between electricity and labor for adjustable output. • Low- and high-skilled workers are more affected than medium-skilled

    Many environmental regulations encourage the use of 'clean' inputs. When the suppliers of such an input have market power, environmental regulation will affect not only the quantity of the input used but also its price. We investigate the effect of the Title IV emissions trading program for sulfur dioxide on the market for low-sulfur coal. We find that the two railroads transporting coal were able to price discriminate on the basis of environmental regulation and geographic location. Delivered prices rose for plants in the trading program relative to other plants, and by more at plants near a low-sulfur coal source.

    2001-09-01

    Considerable efforts have been devoted by econometric researchers to understanding Japanese steel mill (JSM) metallurgical coal valuation policies, and whether such policies disadvantage coal exporters. Much of this research has employed the hedonic regression modeling technique of Rosen and examines the significance of coal quality in establishing market price. This article discusses shortcomings in some such modeling studies, and presents results of additional hedonic modeling to buttress findings of previous work suggesting that cross-cultural bargaining factors rather than coal quality explain lower prices for Australian coals in Japanese market settlements. Policy changes that might be effective in ameliorating bilateral market distortions arising from oligopsony characteristics exhibited in JSM contract settlements are then explored. 29 refs., 2 figs., 2 tabs.

  16. Unconventional Coal in Wyoming: IGCC and Gasification of Direct Coal Liquefaction Residue

    Science.gov (United States)

    Schaffers, William Clemens

    Two unconventional uses for Wyoming Powder River Basin coal were investigated in this study. The first was the use of coal fired integrated gasification combined cycle (IGCC) plants to generate electricity. Twenty-eight different scenarios were modeled using AspenPlusRTM software. These included slurry, mechanical and dried fed gasifiers; Wyodak and Green River coals, 0%, 70%, and 90% CO2 capture; and conventional evaporative vs air cooling. All of the models were constructed on a feed basis of 6,900 tons of coal per day on an "as received basis". The AspenPlus RTM results were then used to create economic models using Microsoft RTM Excel for each configuration. These models assumed a 3 year construction period and a 30 year plant life. Results for capital and operating costs, yearly income, and internal rates of return (IRR) were compared. In addition, the scenarios were evaluated to compare electricity sales prices required to obtain a 12% IRR and to determine the effects of a carbon emissions tax on the sales price. The second part of the study investigated the gasification potential of residue remaining from solvent extraction or liquefaction of Powder River Basin Coal. Coal samples from the Decker mine on the Wyoming-Montana border were extracted with tetralin at a temperature of 360°C and pressure of 250 psi. Residue from the extraction was gasified with CO2 or steam at 833°C, 900°C and 975°C at pressures of 0.1 and 0.4 MPa. Product gases were analyzed with a mass spectrometer. Results were used to determine activation energies, reaction order, reaction rates and diffusion effects. Surface area and electron microscopic analyses were also performed on char produced from the solvent extraction residue.

  17. Land use changes after the period commodities rising price in the Rio Grande do Sul State, Brazil

    Directory of Open Access Journals (Sweden)

    Vicente Celestino Pires Silveira

    Full Text Available ABSTRACT: At the end of the 20th and early 21st century, agricultural systems incorporated definitively a new mission: to generate goods for a world population that continues to grow and whose way of life demand food with low environmental impact. Soybean is the main raw material for the production of biodiesel in Brazil, accountably responsible for 82.4% of the total produced between 2006 and 2013. The Brazilian state of Rio Grande do Sul (RS, which is formed by the Pampa and the Atlantic forest biomes, was responsible for 35.7% of the country's biodiesel production in the referred period. The aim of this paper was to verify the impact of the increased area of soybean cultivation in land use in Rio Grande do Sul State, in the period between 1990 and 2015, considering separately its two biomes (Pampa and Atlantic Forest original areas, using both census dataset and satellite images. We used the period from 1990 to 2000 as before commodity rising price (BCRP and the period from 2000 to 2013 as commodity rising price (CRP. The 505,162 ha from Atlantic Forest biome and 1,192,115ha from Pampa biome were added to soybean production in the CRP period. In the Atlantic Forest, this enlargement occurred in the border of the main production area, while in Pampa biome conversion of natural grassland to crop land was the main reason for the large increment in the cultivated area.

  18. State coal profiles, January 1994

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-02

    The purpose of State Coal Profiles is to provide basic information about the deposits, production, and use of coal in each of the 27 States with coal production in 1992. Although considerable information on coal has been published on a national level, there is a lack of a uniform overview for the individual States. This report is intended to help fill that gap and also to serve as a framework for more detailed studies. While focusing on coal output, State Coal Profiles shows that the coal-producing States are major users of coal, together accounting for about three-fourths of total US coal consumption in 1992. Each coal-producing State is profiled with a description of its coal deposits and a discussion of the development of its coal industry. Estimates of coal reserves in 1992 are categorized by mining method and sulfur content. Trends, patterns, and other information concerning production, number of mines, miners, productivity, mine price of coal, disposition, and consumption of coal are detailed in statistical tables for selected years from 1980 through 1992. In addition, coal`s contribution to the State`s estimated total energy consumption is given for 1991, the latest year for which data are available. A US summary of all data is provided for comparing individual States with the Nation as a whole. Sources of information are given at the end of the tables.

    Pay What You Want (PWYW) and Name Your Own Price (NYOP) are customer driven pricing mechanisms that give customers (some) pricing power. Both have been used in service industries with high fixed costs to price discriminate without setting a reference price. Their participatory and innovative nature gives rise to promotional benefits that do not accrue to posted-price sellers. We explore the nature and effects of these benefits and compare PWYW and NYOP using controlled lab experiments. We sho...

  3. Oil prices and the stock prices of alternative energy companies

    International Nuclear Information System (INIS)

    Henriques, Irene; Sadorsky, Perry

    2008-01-01

    Energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements. While it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies, there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices. In this paper, a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices, technology stock prices, oil prices, and interest rates. Our results show technology stock prices and oil prices each individually Granger cause the stock prices of alternative energy companies. Simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices. These results should be of use to investors, managers and policy makers. (author)

  4. The rising price of oil: a window of opportunity for some Central American and Caribbean countries

    International Nuclear Information System (INIS)

    Lizardi, Carlos Guerrero de; Padilla-Perez, Ramon

    2010-11-01

    This research paper analyzes the direct impact of the rising price of oil on shipping costs of any product to any point in the United States from Central America, Mexico or the Dominican Republic (CAM-DR) versus products from Asia. First, the study provides a brief description of the commercial opening of the countries analyzed and the liberalization of their markets. Second, it analyzes the evolution of the competitiveness of selected countries in the U.S. import market. Third, the study presents an analysis for each product. The hypothesis of this study is that geographical distance will be increasingly key. It is recommended that enhance shipping procedures and time (transit and container stay) be enhanced by simplifying customs procedures and improving port infrastructure. By expanding and improving road and rail infrastructures, countries could reduce shipping costs within their own territories. Besides, to avoid significant gain or loss in market share, it is recommended that the current tariff gaps be maintained or better still, expanded. Furthermore, forming strategic alliances could help producers lower the prices of their exported manufactured products.

  5. Solid fuels. Coal. Economy and resources

    Bautin, F.; Martin-Amouroux, J.M.

    2007-01-01

    The share of coal in the world energy mix (25%) and its possible increase during the next decades is due to its specific use in steelmaking industry and to its excellent competitiveness in fossil-fuel power plants with respect to other energy sources. Its inferior energy efficiency is compensated by lower and more stable prices on international markets. This situation is explained by a strong competition and abundant reserves. However, coal is a strong emitter of greenhouse gases and would be temporarily penalized by the implementation of emission tax or trading systems before the development of carbon sequestration systems. This article presents: the main world markets (consumption per sector of activity, power generation market, coke market, start-up of a synthetic fuels market), the main international coal producers and traders (overview and typology, international trades, transport), the reserves and resources, and the worldwide perspectives (2050 scenarios, climatic risks, CO 2 prices and technological changes).

  8. Japanese investment in Australian coal assets through the demise of concessional financing

    International Nuclear Information System (INIS)

    West, Jason

    2013-01-01

    The Australian coal industry has been described as being a perpetual case of ‘profitless prosperity’. This implies that foreign companies invest in low-margin mining activities with motives other than profit. It is argued that foreign investors and Japanese trading companies in particular used government investment concessions and subsidies to help create oversupply in the seaborne coal market. The aim of this strategy is to depress contract prices at the cost of achieving reasonable profitability levels, which have historically been well below that of other investors in the Australian mining sector. This study shows that the quasi-integration via concessional funding arrangements is not a credible strategy employed by Japanese trading companies or the Japanese Government. The analysis rejects the hypothesis that via foreign direct investment, Japanese companies are securing coal at below average prices. Furthermore we find no clear evidence of Japanese trading companies using their information advantage as equity investors to secure coal at favourable prices during contract negotiations. Finally we examine the investment behaviour of new entrants in the Australian coal production sector to highlight the differences in investment strategy between Japanese companies and other foreign investors regarding the security of supply. - Highlights: ► Past foreign investment practices sacrificed profit to create oversupply of Australian coal. ► Only a small amount of equity capital was required to exert influence over coal output. ► Foreign investors can no longer exploit information advantages to obtain favourable prices. ► Information advantages from partial ownership do not influence supply costs. ► Foreign investors in Australian mining now achieve similar profits to domestic firms.

    The United States produced 257 million short tons of coal in the first quarter of 1992. This was the second highest quarterly production level ever recorded. US coal exports in January through March of 1992 were 25 million short tons, the highest first quarter since 1982. The leading destinations for US coal exports were Japan, Italy, France, and the Netherlands, together receiving 46 percent of the total. Coal exports for the first quarter of 1992 were valued at $1 billion, based on an average price of $42.28 per short ton. Steam coal exports totaled 10 million short tons, an increase of 34 percent over the level a year earlier. Metallurgical coal exports amounted to 15 million short tons, about the same as a year earlier. US coal consumption for January through March 1992 was 221 million short tons, 2 million short tons more than a year earlier (Table 45). All sectors but the residential and commercial sector reported increased coal consumption

  12. The impact of TTIP agreement on the European Union-United States coal trade potential

    Olkuski Tadeusz

    2016-01-01

    Full Text Available The main aim of the paper is to assess the impact of currently negotiated TTIP agreement (Transatlantic Trade and Investment Partnership on the use of hard coal in the EU and the US. Hard coal is the most important fuel in global electricity generation. This also applies to the United States, a leading manufacturer and exporter of this energy source. The US coal is exported to the EU market. The article presents the estimated exports of hard coal from the US to the EU. Due to the fact that price has a major impact on the size of exports, the paper presents the estimated prices, including freight costs, of power coal for the analyzed scenarios. According to one scenario, the US and European prices will be equalized (including freight costs by 2020, while from 2025 on the comparative advantage and competitiveness of the US hard coal will decrease. Taking into account the fact that the export of coal from the United States is free from customs duties, the acceptance of TIPP should not affect the currently existing trade between the two continents and the amount of exported coal. Nevertheless, the question of hard coal economy cannot be separated from other sectors of the energy market, which can be significantly affected by the future agreement.

  14. Analysis of antitrust activity in the coal industry: 1964-1974

    Energy Technology Data Exchange (ETDEWEB)

    Hinson, W.R.

    1975-01-01

    Antitrust activity in the coal industry from 1964 to 1974 is studied for two major areas: 1) acquisitions and mergers, which involve the structure of the industry; and 2) price fixing, bid rigging, and customer allocations, which deal with the behavior of the industry. The government is criticized for the lack of antitrust activity during this time period. Offences of the antitrust laws by suppliers of fuel could have a chain-reaction effect on all commodity prices, because artificially high fuel prices could force other industries to increase their prices. Several recommendations are made: 1) a special section in both the Justice Department and the Federal Trade Commission should be established to handle violations of the antitrust laws occurring in the ''energy market''; 2) nolo contendere pleas and other forms of a consent settlement should be denied as an option for any energy concern accused of transgressing the antitrust laws; 3) all known coal reserves in the U.S. should be rationalized and placed under the supervision of the Federal Energy Administration; 4) a National reporting system for the ownership of coal reserves should be established; and 5) public regulatory commissions should be encouraged to order electric utilities to file private suits when anti-competitive conduct is suspected by coal suppliers.

  15. Economic competitiveness of small modular reactors versus coal and combined cycle plants

    International Nuclear Information System (INIS)

    Alonso, Gustavo; Bilbao, Sama; Valle, Edmundo del

    2016-01-01

    Small modular reactors (SMRs) may be an option to cover the electricity needs of isolated regions, distributed generation grids and countries with small electrical grids. Previous analyses show that the overnight capital cost for SMRs is between 4500 US$/kW and 5350 US$/kW, which is between a 6% and a 26% higher than the average cost of a current large nuclear reactor. This study analyzes the economic competitiveness of small modular reactors against thermal plants using coal and natural gas combined cycle plants. To assess the economic competitiveness of SMRs, three overnight capital costs are considered 4500 US$/kW, 5000 US$/kW and 5350 US$/kW along with three discount rates for each overnight cost considered, these are 3, 7, and 10%. To compare with natural gas combined cycle (CC) units, four different gas prices are considered, these are 4.74 US$/GJ (5 US$/mmBTU), 9.48 US$/GJ (10 US$/mmBTU), 14.22 US$/GJ (15 US$/mmBTU), and 18.96 US$/GJ (20 US$/mmBTU). To compare against coal, two different coal prices are considered 80 and 120 US$/ton of coal. The carbon tax considered, for both CC and coal, is 30 US$/ton CO_2. The results show what scenarios make SMRs competitive against coal and/or combined cycle plants. In addition, because the price of electricity is a key component to guarantee the feasibility of a new project, this analysis calculates the price of electricity for the economically viable deployment of SMRs in all the above scenarios. In particular, this study shows that a minimum price of electricity of 175 US$/MWh is needed to guarantee the feasibility of a new SMR, if its overnight capital cost is 5350 US$/kWe and the discount rate is 10%. Another result is that when the price of electricity is around 100 US$/MWh then the discount rate must be around 7% or less to provide appropriate financial conditions to make SMRs economically feasible. - Highlights: • Small modular reactor (SMR) are economically assessed. • SMR are compared against gas and coal

  16. Sustainable global energy development: The case of coal

    International Nuclear Information System (INIS)

    Brendow, Klaus

    2004-01-01

    Market-driven scenarios anticipate world coal demand to increase during the entire 21st century. The increase during 2000-2030 would range from 53 % to 100 %. Developing countries would take the lead in world coal demand growth. In western Europe, demand, and more so production, would decline, in central and eastern Europe increase. Carbon abatement policies would not impact on coal demand before 2020 - 2030. By 2050 however, under such constraints, coal demand would have declined by one third (only), - less in developing, more in developed countries. Under market conditions, the share of coal in world primary energy supplies, at 26 % in 2000, would decline to 24 % in 2020 and 22 % 2050. Carbon constraints would reduce the share of coal to 11 % in 2050, which (nevertheless) corresponds to 2.1 bill. tce (2000: 3.4 bill. tce). The major short-term competitor of coal would be gas, particularly under CO 2 emission constraints, although marginal gas is hardly better in terms of life cycle GHG emissions than marginal oil or coal. During 2001-2025, the increase of CO 2 emissions from coal (+1.1 bill. t of carbon) would be lower than for gas (+1.3 bill. t) and oil (+1.5 bill. t). In the longer term, new nuclear could emerge as a serious competitor. Electricity generators would remain the predominant customer for coal. By 2030, coal would cover 45 % of world electricity generation compared with 37 % in 2000. By 2020, coal-based methanol and hydrogen would cover 3 % of the world's transportation fuel demand (100 Mtoe), by 2050 14 % (660 Mtoe). Cumulative investments in coal mining, shipping and combustion during 2001-2030 would amount to USD 1900 billion, - 12 % of world investments in energy supply. International prices of coal relative to oil and gas would continue evolving in favour of coal enhancing its competitiveness. Almost nil in 2000, advanced coal combustion technologies would cover 33 % of world power generation in 2030, and 72 % of coal-based power generation

    Eastern Europe currently faces great economic and environmental problems. Among these problems is energy provision. Coal reserves are large but cause pollution while oil and gas need to be used for export. Formal 'clean coal technologies' are simply too expensive to be implemented on a large scale in the current economic crisis. The promised western investment and technological help has simply not taken place, western Europe must help eastern Europe with coal technology. The cheapest such technology is coal-water fuel slurry. It can substitute for oil, but research has not been carried out because of low oil prices. Coal-water fuel is one of the best methods of exploiting low rank coal. Many eastern European low rank coals have a low sulfur content, and thus make a good basis for a clean fuel. Italy and Russia are involved in such a venture, the slurry being transported in a pipeline. This technology would enable Russia to exploit Arctic coal reserves, thus freeing oil and gas for export. In Serbia the exploitation of sub-Danube lignite deposits with dredging mining produced a slurry. This led to the use and development of hot water drying, which enabled the removal of many of the salts which cause problems in pulverized fuel combustion. The system is economic, the fuel safer to transport then oil, either by rail or in pipelines. Many eastern European oil facilities could switch. 24 refs

  19. The renaissance of coal

    International Nuclear Information System (INIS)

    2013-01-01

    There is hardly another energy resource where public opinion and reality lie as far apart as they do for coal. Many think of coal as an inefficient relic from the era of industrialisation. However, such views underestimate the significance of this energy resource both nationally and globally. In terms of global primary energy consumption coal ranks second behind crude oil, which plays a central role in the energy sector. Since global electricity use is due to rise further, coal, being the only energy resource that can meet a growing electricity demand over decades, stands at the beginning of a renaissance, and does so also in the minds of the political leadership. Coal is indispensable as a bridging technology until the electricity demand of the world population can be met primarily through renewable resources.

    Coal Information (1997 edition) is the latest edition of a publication that has been produced annually by the IEA since 1983. The report is intended to provide both Member countries of the OECD and those employed in all sectors of the coal industry with information on current world coal market trends and long-term prospects. It includes information on coal prices, demand, trade, supply, production capacity, transport, environmental issues (including emission standards for coal-fired boilers), coal ports, coal-fired power stations and coal used in non -OECD countries. Part I of the publication contains a wide ranging review of world coal market developments in 1996 and current prospects to 2010. The review is based on historical data of OECD energy supply and demand, data on other world regions, projections of OECD coal supply, demand and trade and information provided by the CIAB. Part II provides, in tabular and graphical form, a more detailed and comprehensive statistical picture of coal developments and future prospects for coal in the OECD, by region and for individual Member countries. Readers interested in projections are strongly advised to read the notes for individual countries in Principles and Definitions in Part II. Coal statistics for non-OECD countries are presented in Part III of the book. Summary data are available on hard coal supply and end-use statistics for about 40 countries and regions world-wide. Data are based on official national submissions to the United Nations in Geneva and New York, national energy publications, information provided to the IEA Secretariat by national statistical offices as well as other unofficial Secretariat sources. Further information on coal used in non-OECD countries is published annually by the IEA in Energy Statistics and Balances of Non-OECD Countries. Also included in Part III are the Survey of Coal Ports world-wide and the Survey of Coal-fired Power Stations in coal-importing countries

  2. Opportunities that abound for British coal--if only

    Energy Technology Data Exchange (ETDEWEB)

    1984-04-01

    The chairman of the National Coal Board discusses primary-energy consumption from 1965, with major emphasis on coal. He points out that coal consumption showed growth after 1975, but before then - except for a boost in 1973 - real expansion has been quite slow. World coal resources and reserves are presented. Because several countries are able to deliver coal into Europe at prices which are lower than the National Coal Board's average cost, Britain must reduce production costs in order to compete more effectively worldwide. Patterns of costs could be improved if more output was to be concentrated at the modern, more-productive collieries. Investment in coal mining is at one of the highest levels of investment of any industry in Britain today.

  3. The come back of liquid coal

    International Nuclear Information System (INIS)

    Caulier, S.

    2010-01-01

    The coal-to-liquid (CTL) process has made important progresses and is now perfectly mastered by the South-African company Sasol. At least 6 CTL facilities are under construction in China. Each will produce 80000 barrels/day of diesel fuel and the production is planned to start up by 2017 or 2018. The CTL process is profitable when the oil barrel price exceeds 100 US$ but it depends also of the coal price. However, the process itself is highly energy consuming and also highly polluting with strong CO 2 emissions. A solution to these drawbacks would come from the implementation of poly-generation (separate generation of energy, electricity and heat), and from the use of a combined cycle with integrated gasification.

    The feasibility of underground coal gasification is evaluated on the basis of a case study for India. India has immense coal reserves at relatively shallow depths compared to Europe, has low wages, an urgent need to expand its power capacity, a strongly rising energy demand and has shown interest in underground coal gasification. Three scenarios including the cases of continued, declining and a strong economic growth were considered. Model calculations allow to compare the cost of the electric power generated by the combustion of the gas produced by underground coal gasification with the cost of the power produced by classic thermal power plants in India for -the reference year 2000.

  5. TRADE-OFFS BETWEEN SEVERANCE TAX REVENUES AND COAL MINING EMPLOYMENT

    OpenAIRE

    Findeis, Jill L.; Shortle, James S.

    1985-01-01

    A severance tax can provide local jurisdictions with additional revenues to finance economic development, yet the imposition of a tax may create coal industry employment losses. This research analyzes this issue by examining the demand for Pennsylvania steam coal, providing estimates of the unconditional own-price elasticities of demand for coal in each of two demand regions. These estimates in conjunction with labor/output coefficient estimates are used to determine the extent to which coal ...

  6. German energy prices top the scale as Commission examines price transparency

    The results of the price transparency directive indicate clearly that gas and electricity prices to both large and small consumers vary widely between member states. And one message which will hit home to large industrial consumers of gas and electricity when they examine the Commission's recent analysis is that relocating or setting up a subsidiary in Germany is a decision which must be taken with care. The Commission's first attempt to examine the directive's operation reveals that the majority of gas and electricity prices in Germany are higher than those in the bulk of other member states. While the reasons for this are known - for electricity it is mainly due to the Kohlepfennig, a surcharge added to power bills to support the uneconomic coal industry -the Commission's analysis focuses on the price difference between member states rather than the various reasons - tariff policy, taxes, environmental costs - for the difference.

    1997-01-01

    Coal is the major primary energy source in Poland and this circumstances requires that the data on coal supply for use in energy planning models should be prepared properly. Economic sectors' development depends on many factors which are usually considered in energy planning models. Thus, data on the development of such sectors as coal mining should be consistent with the economic assumptions made in the energy planning model. Otherwise, coal data could bias the results of the energy planning model. The coal mining and coal distribution models which have been developed at the Polish Academy of Sciences could provide proper coal data of use in ENPEP and other energy planning models. The coal mining model optimizes the most important decisions related to coal productions, such as coal mines development, retirement of non-profitable mines, and construction of new mines. The model uses basic data forecasts of coal mine costs and coal production. Other factors such as demand for coal, world coal prices, etc., are parameters which constitute constraints and requirements for the coal mining development. The output of the model is the amount of coal produced and supply curves for different coal types. Such data are necessary for the coal distribution model and could also be used by ENPEP. This paper describes the model, its structure and how the results of the model could serve as coal-related data for ENPEP. Improvement of some input data forms of the BALANCE module of ENPEP are also suggested in order to facilitate data preparation. (author). 7 figs

  10. Externality costs of the coal-fuel cycle: The case of Kusile Power Station

    Directory of Open Access Journals (Sweden)

    Nonophile P. Nkambule

    2017-09-01

    Full Text Available Coal-based electricity is an integral part of daily life in South Africa and globally. However, the use of coal for electricity generation carries a heavy cost for social and ecological systems that goes far beyond the price we pay for electricity. We developed a model based on a system dynamics approach for understanding the measurable and quantifiable coal-fuel cycle burdens and externality costs, over the lifespan of a supercritical coal-fired power station that is fitted with a flue-gas desulfurisation device (i.e. Kusile Power Station. The total coal-fuel cycle externality cost on both the environment and humans over Kusile's lifespan was estimated at ZAR1 449.9 billion to ZAR3 279 billion or 91c/kWh to 205c/kWh sent out (baseline: ZAR2 172.7 billion or 136c/kWh. Accounting for the life-cycle burdens and damages of coal-derived electricity conservatively, doubles to quadruples the price of electricity, making renewable energy sources such as wind and solar attractive alternatives. Significance: The use of coal for electricity generation carries a heavy cost for social and ecological systems that goes far beyond the price we pay for electricity. The estimation of social costs is particularly important to the electric sector because of non-differentiation of electricity prices produced from a variety of sources with potentially very dissimilar environmental and human health costs. Because all electricity generation technologies are associated with undesirable side effects in their fuelcycle and lifespan, comprehensive comparative analyses of life-cycle costs of all power generation technologies is indispensable to guide the development of future energy policies in South Africa.

    1982-05-01

    The New England Power Company (NEPCO) recently converted Brayton Point Power Station Units 1, 2, and 3 from oil to coal. The coal conversion project is the largest coal conversion project in the nation to date. Stone and Webster Engineering Corporation (SWEC) was hired as the engineer/constructor for the project. Units 1 and 2 are 250-MW Combustion Engineering boilers, and Unit 3 is a 650-MW Babcock and Wilcox boiler. All three units were originally designed to burn pulverized coal but were converted to oil during the years of low oil prices. Studies performed by NEPCO and SWEC indicated that the areas discussed in the following paragraphs required upgrading before the units could efficiently burn coal and meet Federal and State environmental requirements. All units have been converted and are operating. This paper discusses design modifications required to burn coal, startup, and initial operating problems, and solutions.

    Rising health care spending, led by rising prices, has had an enormous impact on the economy, especially on the federal budget. Our work shows that if rapid growth in health care prices continues, under current institutional arrangements, real economic growth and employment will be lower during the next two decades than if health price inflation were somehow reduced. How big the losses are and which sectors bear the brunt of the costs vary depending on how society chooses to fund the federal budget deficit that stems from the rising cost of federal health care programs.

  15. CO2 Price Impacts on Nuclear Power Plant Competitiveness in Croatia

    2010-01-01

    Long term power system planning faces growing number of concerns and uncertainties, which is especially true for nuclear power plants due to their high investment costs and financial risk. In order to analyze competitiveness of nuclear power plants and optimize energy mix, existing models are not sufficient anymore and planners need to think differently in order to face these challenges. Croatia will join EU ETS (European Emission Trading Scheme) with accession to EU (probably in 2012). Thus, for Croatian electrical system it is very important to analyze possible impacts of CO 2 emissions. Analysis presented in this paper is done by electricity market simulation model PLEXOS which was used for modelling Croatian electrical system during development of the Croatian Energy Strategy in 2008. Paper analyzes impacts of CO 2 price on competitiveness of nuclear power plant within Croatian power system between 2020 and 2025. Analyzes are focused on how nuclear power plant influences total emission from the power system regarding coal and gas prices, average electricity price regarding CO 2 , coal and gas prices price. Results of this paper are showing that with emissions from Energy strategy development scenario with two new coal power plants (600 MW each) and two new gas power plants (400 MW each) until 2020, Croatia does not meet Kyoto target due to this emissions from power system. On the other side, introduction of nuclear power plants presented in this paper (1000 MW instead of one coal and one gas power plant) means nearly 6.5 Mt CO 2 emissions less annually and gives possibility to achieve Kyoto target (as this reduced amount represents nearly 22 % of Croatian Kyoto target). Results are also showing how increase in CO 2 price is enhancing competitiveness of a nuclear power plant.(author).

    With an objective to learn mechanisms in low-rank coal reformation processes, change of properties on coal surface was discussed. Difficulty in handling low-rank coal is attributed to large intrinsic water content. Since it contains highly volatile components, it has a danger of spontaneous ignition. The hot water drying (HWD) method was used for reformation. Coal which has been dry-pulverized to a grain size of 1 mm or smaller was mixed with water to make slurry, heated in an autoclave, cooled, filtered, and dried in vacuum. The HWD applied to Loy Yang and Yallourn coals resulted in rapid rise in pressure starting from about 250{degree}C. Water content (ANA value) absorbed into the coal has decreased largely, with the surface made hydrophobic effectively due to high temperature and pressure. Hydroxyl group and carbonyl group contents in the coal have decreased largely with rising reformation treatment temperature (according to FT-IR measurement). Specific surface area of the original coal of the Loy Yang coal was 138 m{sup 2}/g, while it has decreased largely to 73 m{sup 2}/g when the reformation temperature was raised to 350{degree}C. This is because of volatile components dissolving from the coal as tar and blocking the surface pores. 2 refs., 4 figs.

    We introduce an agent-based model, in which agents set their prices to maximize profit. At steady state the market self-organizes into three groups: excess producers, consumers and balanced agents, with prices determined by their own resource level and a couple of macroscopic parameters that emerge naturally from the analysis, akin to mean-field parameters in statistical mechanics. When resources are scarce prices rise sharply below a turning point that marks the disappearance of excess producers. To compare the model with real empirical data, we study the relationship between commodity prices and stock-to-use ratios in a range of commodities such as agricultural products and metals. By introducing an elasticity parameter to mitigate noise and long-term changes in commodities data, we confirm the trend of rising prices, provide evidence for turning points, and indicate yield points for less essential commodities.

    2009-07-01

    This study analyzes China's coal industry by focusing on four related areas. First, data are reviewed to identify the major drivers of historical and future coal demand. Second, resource constraints and transport bottlenecks are analyzed to evaluate demand and growth scenarios. The third area assesses the physical requirements of substituting coal demand growth with other primary energy forms. Finally, the study examines the carbon- and environmental implications of China's past and future coal consumption. There are three sections that address these areas by identifying particular characteristics of China's coal industry, quantifying factors driving demand, and analyzing supply scenarios: (1) reviews the range of Chinese and international estimates of remaining coal reserves and resources as well as key characteristics of China's coal industry including historical production, resource requirements, and prices; (2) quantifies the largest drivers of coal usage to produce a bottom-up reference projection of 2025 coal demand; and (3) analyzes coal supply constraints, substitution options, and environmental externalities. Finally, the last section presents conclusions on the role of coal in China's ongoing energy and economic development. China has been, is, and will continue to be a coal-powered economy. In 2007 Chinese coal production contained more energy than total Middle Eastern oil production. The rapid growth of coal demand after 2001 created supply strains and bottlenecks that raise questions about sustainability. Urbanization, heavy industrial growth, and increasing per-capita income are the primary interrelated drivers of rising coal usage. In 2007, the power sector, iron and steel, and cement production accounted for 66% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units would save only 14% of projected 2025 coal demand for the power sector. A new wedge of

  20. The impact of resource tax reform on China's coal industry

    2017-01-01

    Contributing to approximately two-thirds of primary energy consumption, coal usage is the focus of China's energy policies. To regulate the resource taxation system and reduce the burden of coal enterprises, the Chinese government launched a reform of its resource tax system in 2014 for coal, introducing the ad valorem system to replace the volume-based system that had been in place for the preceding thirty years. To assess the impact of the tax reform, this paper constructs two-stage dynamic game models by taking the coal and coal-fired power industries as the players. The market situations of shortage and oversupply are investigated separately. Empirical data are collected to estimate the model parameters for numerical simulations. The model results suggest that the tax reform will reduce both coal prices and the coal industry profitability if the tax levied on each ton of coal is maintained at the same level as before the reform, regardless of whether the market is in a shortage or an oversupply situation. However, the increased buyer's power will amplify the effect of the tax reform. The numerical simulations also provide an estimation of the tax rate of the ad valorem system that maintains the profit of the coal industry. Considering the demand and supply situations in China's coal market, policy recommendations are provided to guide further reform of China's resource tax system. - Highlights: • The paper examines the influence of resource tax reform on China's coal industry. • We construct two-stage game models between coal and coal-fired power industries. • Market situations of shortage and oversupply are studied in two taxation systems. • Coal price will decrease if maintaining the tax levied on each ton of coal the same. • To achieve the reform objective, the ad valorem tax rate should not be set too high.

    Full Text Available Recent research shows that the efforts to limit climate change should focus on reducing the emissions of carbon dioxide over other greenhouse gases or air pollutants. Many countries are paying substantial attention to carbon emissions to improve air quality and public health. The largest source of carbon emissions from human activities in some countries in Europe and elsewhere is from burning fossil fuels for electricity, heat, and transportation. The prices of fuel and carbon emissions can influence each other. Owing to the importance of carbon emissions and their connection to fossil fuels, and the possibility of [1] Granger (1980 causality in spot and futures prices, returns, and volatility of carbon emissions, crude oil and coal have recently become very important research topics. For the USA, daily spot and futures prices are available for crude oil and coal, but there are no daily futures prices for carbon emissions. For the European Union (EU, there are no daily spot prices for coal or carbon emissions, but there are daily futures prices for crude oil, coal and carbon emissions. For this reason, daily prices will be used to analyse Granger causality and volatility spillovers in spot and futures prices of carbon emissions, crude oil, and coal. As the estimators are based on quasi-maximum likelihood estimators (QMLE under the incorrect assumption of a normal distribution, we modify the likelihood ratio (LR test to a quasi-likelihood ratio test (QLR to test the multivariate conditional volatility Diagonal BEKK model, which estimates and tests volatility spillovers, and has valid regularity conditions and asymptotic properties, against the alternative Full BEKK model, which also estimates volatility spillovers, but has valid regularity conditions and asymptotic properties only under the null hypothesis of zero off-diagonal elements. Dynamic hedging strategies by using optimal hedge ratios are suggested to analyse market fluctuations in the

    Developers and promoters of coal-water slurries and similar CWF (coal-water fuel) technologies have had a hard time winning converts since they unveiled their first commercial processes in the 1970s. The economic appeal of such processes, marginal at best, varies with the price of oil. Nevertheless, the technology is percolating, as geopolitics and environmental pressures drive new processes. Such fuels are becoming increasingly important to coal-rich, oil-poor nations such as China, as they attempt to build an onshore fuel supply. Meanwhile, improvements are changing the way coal-fired processes are viewed. Where air pollution regulations once discouraged the use of coal fuels, new coal processes have been developed that cut nitrous oxides (NOx) emissions and provide a use for coal fines, previously viewed as waste. The latest developments in the field were all on display at the 19th International Technical Conference on Coal Utilization and Fuel Systems, held in Clearwater, Fla., on March 21--24. At this annual meeting, sponsored by the Coal and Slurry Technology Association, (Washington, D.C.) and the Pittsburgh Energy Technology Center of the US Dept. of Energy (PETC), some 200 visitors from around the work gathered to discuss the latest developments in coal slurry utilization--new and improved processes, and onstream plants.

    An overview of brown and black coal mining in the Czech Republic is presented, and problems of the extent of coal reserves and of the profitability of deep black coal mining are discussed. Costs of coal mining in foreign countries are given. Coal mining in the Czech Republic can be expected to be loss-making unless coal prices are increased. Since coal resources in the Czech Republic are limited, additional nuclear power plants will have to be constructed or else coal for power generation will have to be imported. The environmental aspects of coal mining and burning are discussed. Medium-term and long-term solutions to reduce the environmental burden include thermal power plant desulfurization, application of the fluidized-bed combustion regime to coals with large ash and/or sulfur contents, and introduction of gas in towns and power plants. In the short run, large-scale consumers in towns and coal basins should be obliged to accumulate reserves of low-sulfur coal for later use. (J.B.). 2 tabs., 3 figs., 8 refs

    International Nuclear Information System (INIS)

    Attanasi, E.

    2000-01-01

    Electrical utility deregulation will force power plants to compete for sales because they will not longer have captive markets. Market uncertainty and uncertainty about future environmental regulations have encouraged power plants to shift to low sulfur coal and/or to use emissions allowances to comply with Phase 2 of the 1990 Clean Air Act Amendments. Mines in Northern and Central Appalachia and the Illinois Basin shipped 240 million tons of non-compliance coal to power plants without scrubbers in 1997. Under Phase 2, this coal will be replaced by low sulfur coal and/or be used with emission permits. It is possible that Powder River Basin coal production will have to increase by over 200 million tons/year to meet new demand. The prices of emissions permits will impose penalties on non-compliance coal that will probably drive out marginal coal producers. For example, if the cost of an emission permit is $200, coal from the Pittsburgh bed could bear a sulfur penalty of $6.55 per ton and similarly, coal from the Herrinbed could bear a penalty of $8.64 per ton

    The fact that CN's Coal Business Unit moved just under 50 million t of coal in 2001 would have been unimaginable just a year earlier, as CN's coal franchise faced a number of challenges last year. On the metallurgical side, where bituminous coal is used in steel production, rising extraction costs in relation to national and international values forced the closure of three CN-served mines in 2000: TeckCominco's Quinteet mine in British Columbia; Smoky River Coal's Smoky River facility and Luscar's Gregg River mine, Alberta. As for thermal coal, utilities had been moving to alternative fuels, maintaining only low coal inventories, and there were few plans for new coal plants. The article explains how North America's railroad helps fuel growing demand for thermal and metallurgical coal. 5 photos.

    The structure and distribution of organic sulfur in coals of different rank and different sulfur content were studied by combining mild organic solvent extraction with XPS technology. The XPS results have shown that the distribution of organic sulfur in coal is related to the degree of metamorphism of coal. Namely, thiophenic sulfur content is reduced with decreasing metamorphic degree; sulfonic acid content rises with decreasing metamorphic degree; the contents of sulfate sulfur, sulfoxide and sulfone are rarely related with metamorphic degree. The solvent extraction and GC/MS test results have also shown that the composition and structure of free and soluble organic sulfur small molecules in coal is closely related to the metamorphic degree of coal. The free organic sulfur small molecules in coal of low metamorphic degree are mainly composed of aliphatic sulfides, while those in coal of medium and high metamorphic degree are mainly composed of thiophenes. Besides, the degree of aromatization of organic sulfur small molecules rises with increasing degree of coalification.

    The report deals with the use of coal and coke in Sweden during 1994. Some information about technology, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from Statistics Sweden have also been used.The use of steam coal for heating purposes has been unchanged during 1994 at a level of 1 Mtons. The production in the cogeneration plants has been constant, but has increased for electricity production. The minor plants have increased their use of forest fuels. The use of steam coal will probably go down in the next years both for heat and cogeneration plants. During the top year 1987 coal was used in 18 hot water and 11 cogeneration plants. 1994 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in industry has been constant at the level 0.7 Mtons. The import of metallurgical coal in 1993 was 1.6 Mtons, like 1992. Import of 0.3 Mtons of coke gives the total consumption of coke in industry as 1.5 Mtons. the average price of steam coal imported to Sweden was 317 SEK/ton, 3% higher than 1993. All Swedish plants meet their emission limit of dust, SO 2 and NO x as given by county administrations or concession boards. The cogeneration plants all have some SO 2 removal system. The biggest cogeneration plant (Vaesteraas) has recently invested in a SCR NO x cleaning system. Most other plants use low NO x burners or SNR injection systems based on ammonia or urea. 2 figs, 13 tabs

    Coal, a fuel that once dominated the global energy scene, is staging a come-back despite being environmentally dirty. The purpose of the paper is to analyse the return of King Coal to find out whether it is likely to be regain its dominance in the global energy in the future. In analysing the metamorphosis of the coal industry, the paper looks at the historical evolution of the industry and analyses the factors behind the change. The deficiencies of coal's competitors are also analysed. Using a scenario analysis, the future role of coal in the global energy mix is estimated as well. The paper finds that despite the domination of hydrocarbons in the global energy mix, coal has maintained a steady share and in some countries, it remained the main fuel. With the concerns of high-oil prices and peak oil, coal is regaining its domination in the power sector around the world. The industry has reformed and restructured itself to remain competitive. Consequently, it has the possibility of staging a come back as a dominant fuel.

    1987-01-01

    A process for electrochemically gasifying coal by establishing a flowing stream of coal particulate slurry, electrolyte and electrode members through a transverse magnetic field that has sufficient strength to polarize the electrode members, thereby causing them to operate in combination with the electrolyte to electrochemically reduce the coal particulate in the slurry. Such electrochemical reduction of the coal produces hydrogen and carbon dioxide at opposite ends of the polarized electrode members. Gas collection means are operated in conjunction with the process to collect the evolved gases as they rise from the slurry and electrolyte solution.

    1996-01-01

    In Asia, coal currently accounts for over 40 percent of the fossil fuel used for commercial energy. This paper briefly surveys the forces that are likely to decide the future role coal will play as a prime source of energy in the vigorous economies of Asia. As Australia is well placed to profit from Asia's growing need for coal, the challenge to Australian coal suppliers is how to maximize its potential contribution. Four-fifths of all new coal fired electrical generating capacity in the world in the next decade will be located in Asia. Three-quarters of Australia's coal exports are to Asian customers and, conversely, 40 percent of Asian imports are from Australia. Australian coal suppliers have established ties and a depth of marketing experience in the region on which to build.

    Toalster, J.

    1992-01-01

    In this paper, four different, popular approaches to the analysis of oil price movements will be considered and an alternative method will be proposed. Whilst we await the development of a rigorous theoretical framework within which to evaluate the phenomenon of oil price movements some progress may be effected by an amalgam of approaches, with the traditional supply and demand model being supplemented by observations regarding political and social developments in particular countries or regions, together with an assessment of emerging and prospective technological achievements. In this way it should be possible to identify the critical influences at work, from which it should also be possible to select either the single most important variable or combination of variables, affecting the oil price. Moreover, it is my belief that the crucial variables influencing the oil price almost certainly, are more likely to be political and social, rather than economic. In this context and notwithstanding the fact that there is only a minimal level of surplus productive capacity in the world oil industry at present (perhaps 1-2 million b/d albeit rising rapidly), it is reasonable to conclude that oil prices will average around $18-19 a barrel for North Sea Brent in 1992 and 1993, with oscillations of $2-4 a barrel either side, rising slightly in 1994 to $19-20 a barrel and to $20-21 a barrel in 1995. Thereafter, the most likely outcome is for a rise in line with inflation (say $ a barrel/annum) with no prospect of an upward spike, because demand will be weaker than most commentators expect up to the year 2000, whilst OPEC oil supplies will be substantially higher than the consensus forecast.

    Phase 1 survey in fiscal 1996 was conducted based on `Agreement on the comprehensive survey of a coal transportation system in South Sumatra` concluded between NEDO and the Ministry of Mine and Energy in Indonesia. In the survey, conducted were collection of data on coal fields and site surveys, collection of data on inland transportation and site surveys, collection of data on harbors and site surveys, and worked out were a simplified database and a coal transportation plan by optimization of the coal chain system. The area for survey is the periphery of the Musi River of South Sumatra. The results of the simulation by LP models were as follows: When the coal of Bukit Asam coal mine is $25/t in price, only coal of 5500Kcal/kg is profitable, and when $27/t in price, coal of 4500Kcal/kg also becomes profitable. This shows that if the coal is of good quality, it can pay arriving at Suralaya, independent of the distance of transportation. 47 figs., 63 tabs.

    This report was prepared in response to a request by the US Department of energy (DOE). The principal objectives of the study were to assess the current DOE coal program vis-a-vis the provisions of the Energy Policy Act of 1992 (EPACT), and to recommend the emphasis and priorities that DOE should consider in updating its strategic plan for coal. A strategic plan for research, development, demonstration, and commercialization (RDD and C) activities for coal should be based on assumptions regarding the future supply and price of competing energy sources, the demand for products manufactured from these sources, technological opportunities, and the need to control the environmental impact of waste streams. These factors change with time. Accordingly, the committee generated strategic planning scenarios for three time periods: near-term, 1995--2005; mid-term, 2006--2020; and, long-term, 2021--2040. The report is divided into the following chapters: executive summary; introduction and scope of the study; overview of US DOE programs and planning; trends and issues for future coal use; the strategic planning framework; coal preparation, coal liquid mixtures, and coal bed methane recovery; clean fuels and specialty products from coal; electric power generation; technology demonstration and commercialization; advanced research programs; conclusions and recommendations; appendices; and glossary. 174 refs.

    The cost of cancer drugs forms a rising proportion of health care budgets worldwide. A number of studies have examined international comparisons of initial cost, but there is little work on postlicensing price increases. To examine this, we compared cancer drug prices at initial sale and subsequent price inflation in the United States and United Kingdom and also reviewed relevant price control mechanisms. The 10 top-selling cancer drugs were selected, and their prices at initial launch and in 2015 were compared. Standard nondiscounted prices were obtained from the relevant annual copies of the RED BOOK and the British National Formulary. At initial marketing, prices were on average 42% higher in the United States than in the United Kingdom. After licensing in the United States, all 10 drugs had price rises averaging an overall annual 8.8% (range, 1.4% to 24.1%) increase. In comparison, in the United Kingdom, six drugs had unchanged prices, two had decreased prices, and two had modest price increases. The overall annual increase in the United Kingdom was 0.24%. Cancer drug prices are rising substantially, both at their initial marketing price and, in the United States, at postlicensing prices. In the United Kingdom, the Pharmaceutical Price Regulation Scheme, an agreement between the government and the pharmaceutical industry, controls health care costs while allowing a return on investment and funds for research. The increasing costs of cancer drugs are approaching the limits of sustainability, and a similar government-industry agreement may allow stability for both health care provision and the pharmaceutical industry in the United States.

  18. Options for near-term phaseout of CO(2) emissions from coal use in the United States.

    The global climate problem becomes tractable if CO(2) emissions from coal use are phased out rapidly and emissions from unconventional fossil fuels (e.g., oil shale and tar sands) are prohibited. This paper outlines technology options for phasing out coal emissions in the United States by approximately 2030. We focus on coal for physical and practical reasons and on the U.S. because it is most responsible for accumulated fossil fuel CO(2) in the atmosphere today, specifically targeting electricity production, which is the primary use of coal. While we recognize that coal emissions must be phased out globally, we believe U.S. leadership is essential. A major challenge for reducing U.S. emissions is that coal provides the largest proportion of base load power, i.e., power satisfying minimum electricity demand. Because this demand is relatively constant and coal has a high carbon intensity, utility carbon emissions are largely due to coal. The current U.S. electric grid incorporates little renewable power, most of which is not base load power. However, this can readily be changed within the next 2-3 decades. Eliminating coal emissions also requires improved efficiency, a "smart grid", additional energy storage, and advanced nuclear power. Any further coal usage must be accompanied by carbon capture and storage (CCS). We suggest that near-term emphasis should be on efficiency measures and substitution of coal-fired power by renewables and third-generation nuclear plants, since these technologies have been successfully demonstrated at the relevant (commercial) scale. Beyond 2030, these measures can be supplemented by CCS at power plants and, as needed, successfully demonstrated fourth-generation reactors. We conclude that U.S. coal emissions could be phased out by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade. Elimination of fossil fuel subsidies and a substantial rising price on carbon emissions are the

    Globally, there is a growing concern about fuel diversity and security of supply, particularly with regard to oil and natural gas. In contrast, coal is available from a much wider range of sources and has greater price stability. Consequently, coal use is increasing rapidly, and by 2030 may well reach a level of more than 4,500 Mtoe, corresponding to close to a doubling of current levels. However, at the same time, tightening regulations will require better solutions for achieving environmental compliance, for which coal has a number of key issues to address. Most of the coal will be used in the power generation sector. Consequently, the key research challenges are to develop and deploy methods by which coal can be used cleanly, efficiently, and in a sustainable way. These include improvements to existing coal utilisation technologies, particularly to improve operational flexibility and availability, while reducing energy use through higher efficiencies. There is an increasing need to ensure improved emissions control, with the emphasis on achieving ever-lower emissions of particulates, SO{sub 2} and NO{sub x} while also introducing control of trace species, particularly mercury. Alongside this, a key challenge is the integration of techniques that can capture CO{sub 2} then transport and store it within secure geological formations, thereby resulting in near zero emissions of CO{sub 2}. From a power plant perspective, the need is to achieve such integration while minimising any adverse impact on power plant efficiency, performance of existing emissions control systems, operational flexibility and availability. At the same time, means to minimize the additional costs associated with such technology must be established.

  2. Oil prices and economic growth

    There is no limit to the sources of hydrocarbons (whether pumped out of the earth or produced in factories) for the next few decades, but there is and will be a need for increasingly complex and costly techniques as the usual sources of petroleum run out. Does this mean that prices will keep on rising? Probably, since environmental costs must be added onto direct costs. The mining of oil out of 'tar sands', for example, or the production of hydrocarbons by the chemical industry will have a significant impact owing to the emission of greenhouse gases. If prices do rise in the short or middle term, the cause will have to do more with the calendar of investments than with the availability of energy and its costs. In the long run however, price hikes are not all that certain. A few points for analyzing and predicting the macro-and micro-economic effects of fluctuating oil prices are discussed. (author)

    This paper reports on developing gas turbine systems that can use coal or a coal-based fuel ensures that the United States will have cost-effective environmentally sound options for supplying future power generation needs. Power generation systems that marry coal or a coal-based fuel to a gas turbine? Some matchmakers would consider this an unlikely marriage. Historically, most gas turbines have been operated only on premium fuels, primarily natural gas or distillate oil. The perceived problems from using coal or coal-based fuels in turbines are: Erosion and deposition: Coal ash particles in the hot combustion gases passing through the expander turbine could erode or deposit on the turbine blades. Corrosion: Coal combustion will release alkali compounds form the coal ash. Alkali in the hot gases passing through the expander turbine can cause corrosion of high-temperature metallic surfaces. Emissions: coal contains higher levels of ash, fuel-bound sulfur and nitrogen compounds, and trace contaminants than premium fuels. Meeting stringent environmental regulations for particulates, sulfur dioxide (SO 2 ), nitrogen oxides (NO x ), and trace contaminants will be difficult. Economics: Coal-based systems are expensive to build. The difference in price between coal and premium fuels must be large enough to justify the higher capital cost

    Maternal malnutrition in Bangladesh is a persistent health issue and is the product of a number of complex factors, including adherence to food 'taboos' and a patriarchal gender order that limits women's mobility and decision-making. The recent global food price crisis is also negatively impacting poor pregnant women's access to food. It is believed that those who are most acutely affected by rising food prices are the urban poor. While there is an abundance of useful quantitative research centered on maternal nutrition and food insecurity measurements in Bangladesh, missing is an understanding of how food insecurity is experienced by people who are most vulnerable, the urban ultra-poor. In particular, little is known of the lived experience of food insecurity among pregnant women in this context. This research investigated these lived experiences by exploring food provisioning strategies of urban, ultra-poor, pregnant women. This knowledge is important as discussions surrounding the creation of new development goals are currently underway. Using a focused-ethnographic approach, household food provisioning experiences were explored. Data from participant observation, a focus group discussion and semi-structured interviews were collected in an urban slum in Dhaka, Bangladesh. Interviews were undertaken with 28 participants including 12 pregnant women and new mothers, two husbands, nine non-pregnant women, and five health care workers. The key findings are: 1) women were aware of the importance of good nutrition and demonstrated accurate, biomedically-based knowledge of healthy eating practices during pregnancy; 2) the normative gender rules that have traditionally constrained women's access to nutritional resources are relaxing in the urban setting; however 3) women are challenged in accessing adequate quality and quantities of food due to the increase in food prices at the market. Rising food prices and resultant food insecurity due to insufficient incomes are

    2004-01-01

    This paper examined electricity pricing issues for both the immediate future as well as over the long term. The near term outlook resources for the summer of 2004 were reviewed. Intermediate critical supply and demand issues were projected with consideration given to the return of the Pickering A plant and coal phase out. In the long term, it was considered that pricing and demand would reflect conservation issues and demand side response, as well as the timing of Requests For Proposals (RFPs) and the phase out of coal-fired capacity. The impact of the coal phase-out in Ontario was examined, with particular reference to timing and market structure implications. Potential conservation impacts were presented and projected Ontario supply/demand balances were evaluated. The challenges facing the new market structure include pricing dynamics and a reliance on RFPs. The significance of specifying diversity objectives was also discussed. It was concluded that the Ontario Ministry of Energy should play a role in establishing targets for conservation, renewable energy and the overall supply of electricity. Rigorous analysis is necessary before specifying targets in terms of hydroelectric and nuclear generation as opposed to non-fossil generation. tabs., figs

    Coal markets continued to revive during August, as year-to-date production advanced to close to within 5.9 million tons, or 1.0%, of 1986's running total for the same time span. The dynamo behind the resurgence continues to be electric power production. Coal consumption by utilities had climbed to 11 million tons by the middle of the year, spurred by rising industrial usage and increased commercial and residential demands. However, the situation has now changed due to the decline in the US economy. The paper discusses this decline and the likely consequences of various policies aimed at stabilising the economy. Deficit reduction is seen as a sensible response to the crisis and the paper forecasts that this could lead to an increase in industrial output and demand for electricity with a consequent rise in coal usage. Similarly, new home construction could increase to the benefit of residential electricity sales and coal consumption in turn. 1 tab.

    Poland's accession to the European Union has reduced the remnants of import barriers. Moreover, the consolidation and commercialization of the energy sector, the implementation of climate package elements and a whole host of other determinants have caused hard coal mining to begin functioning in a highly competitive market, and its negotiating position, as well as the possibility of survival, depends not only on the level of coal prices in international markets, but also on internal competition. This paper discusses the position of power coal on international markets and presents some current problems concerning the functioning of particular segments of the hard coal market in the European Union and Poland in terms of opportunities and threats that are a result of climate and energy policy.

    This report presents the final results of the first assessment of both coal resources and reserves for all significant coal beds in the entire Powder River Basin, northeastern Wyoming and southeastern Montana. The basin covers about 19,500 square miles, exclusive of the part of the basin within the Crow and Northern Cheyenne Indian Reservations in Montana. The Powder River Basin, which contains the largest resources of low-sulfur, low-ash, subbituminous coal in the United States, is the single most important coal basin in the United States. The U.S. Geological Survey used a geology-based assessment methodology to estimate an original coal resource of about 1.16 trillion short tons for 47 coal beds in the Powder River Basin; in-place (remaining) resources are about 1.15 trillion short tons. This is the first time that all beds were mapped individually over the entire basin. A total of 162 billion short tons of recoverable coal resources (coal reserve base) are estimated at a 10:1 stripping ratio or less. An estimated 25 billion short tons of that coal reserve base met the definition of reserves, which are resources that can be economically produced at or below the current sales price at the time of the evaluation. The total underground coal resource in coal beds 10–20 feet thick is estimated at 304 billion short tons.

    At the coalfield of Wuda (Inner Mongolia, PR China) extensive underground coal fires cause widespread thermal and oxidative effects in coal seams. Within phase B of the Coal Fire Research Project of the Sino-German Initiative, methods for innovative fire-extinguishing technologies were investigated in multifaceted research approaches. Extensive investigations of oxidative and thermally affected coal seams in coal fire zone 18 were conducted in 2008 prior to application of new fire-extinguishing methods. We present results from the outcrop of coal seam No. 4 in the fire zone 18. The coal of seam No. 4 is of Early Permian age and belongs stratigraphically to the Shanxi Formation. The unaffected coal displays a high volatile bituminous A rank with a background value of random vitrinite reflectance ranging from 0.90 to 0.96 % Rr. Coal channel samples were coallected at actively extracted coal faces along multiple profiles with surface temperatures ranging from about 50° to 600°C. Microscopic examinations revealed a variety of products of coal exposure to the fire. Within coal samples, a marked rise in vitrinite reflectance from background values to 5.55% Rr (6.00 % Rmax) is encountered. In addition, a number of coal samples showed suppressed vitrinite reflectances ranging between 0.82 to 0.88% Rr. Further, seemingly heat unaffected coal samples display intensive development of oxidations rims at coal grain edges and cracks as well as shrinkage cracks and formation of iron oxides/hydroxides. Instead, thermally affected coal samples with higher coalification grade are further characterised by development of macropores (devolatilisation pores) in vitrinitic streaks, transformation of liptinite to meta-liptinite and micrinite as well as by natural coke particles of mostly porous nature and fine to coarse grained anisotropic mosaic. Coal petrographic investigations confirmed a hypothesis that both, oxidations as well as low temperature carbonisation govern the thermal

It is feared, however, that the price of the bituminous coal from these areas may soar if demand increases. As for sub-bituminous coal, its price is far more stable because its reserves are basically limitless. The sub-bituminous coal, however, is not expected to be imported to Japan in the very near future because it is low in calorific power and fails to meet the conditions prerequisite to Japan's boiler fuel. Illinois can receive large orders but its coal contains more sulfur than the Western coal and a longer distance has to be covered for its transportation. As for transportation to the West Cost, freight cars are available and the port capacity can be enlarged dependent on the magnitude of demand for coal. Loading a deep draft bulk ship off shore with coarse coal slurry by pipeline is an attractive scheme. (NEDO)

Savings in 'present value' operating costs of heating systems which would be achieved by switching from oil to coal are presented for New England, the Middle Atlantic and East North Central sub-regions at different interest rates from 10 to 30%, and assuming low rates of growth in petroleum prices. These savings define the extra amount of money the user would be prepared to pay to purchase a coal slurry system. At a purchase price of 2500 dollars, this option would only be profitable for commercial users.

    In response to a 1980 Department of Energy solicitation, the General Refractories Company submitted a Proposal for a feasibility study of a low Btu gasification facility for its Florence, KY plant. The proposed facility would substitute low Btu gas from a fixed bed gasifier for natural gas now used in the manufacture of insulation board. The Proposal from General Refractories was prompted by a concern over the rising costs of natural gas, and the anticipation of a severe increase in fuel costs resulting from deregulation. The proposed feasibility study is defined. The intent is to provide General Refractories with the basis upon which to determine the feasibility of incorporating such a facility in Florence. To perform the work, a Grant for which was awarded by the DOE, General Refractories selected Dravo Engineers and Contractors based upon their qualifications in the field of coal conversion, and the fact that Dravo has acquired the rights to the Wellman-Galusha technology. The LBG prices for the five-gasifier case are encouraging. Given the various natural gas forecasts available, there seems to be a reasonable possibility that the five-gasifier LBG prices will break even with natural gas prices somewhere between 1984 and 1989. General Refractories recognizes that there are many uncertainties in developing these natural gas forecasts, and if the present natural gas decontrol plan is not fully implemented some financial risks occur in undertaking the proposed gasification facility. Because of this, General Refractories has decided to wait for more substantiating evidence that natural gas prices will rise as is now being predicted.

    The potential effect that food prices may have on the health of the U.S. population needs to be further explored, particularly in light of the rising food prices currently being observed. Declining food prices over time have been singled out as a main contributor, for example, to the rising trend in obesity. In this paper we use data from the Bureau of Labor Statistics, the American Chamber of Commerce Researchers Association, the Consumer Expenditure Survey, and the United States Department of Agriculture to analyze trends in various types of food prices, to create a food price index, and to estimate the price of a calorie. Results may be used by future researchers in estimating the health implications of these trends. We find that while the general trend in food prices has been declining, that of restaurant meal prices and prices of fruits and vegetables has risen over time. It is doubtful that the decline in food prices has been sufficiently large to account for the large increase in caloric intake that is said to have contributed to the obesity epidemic in the U.S.

  19. Productivity Improvement in Underground Coal Mines - A Case Study

    2013-01-01

    Full Text Available Improvement of productivity has become an important goal for today's coal industry in the race to increase price competitiveness. The challenge now lying ahead for the coal industry is to identify areas of waste, meet the market price and maintain a healthy profit. The only way to achieve this is to reduce production costs by improving productivity, efficiency and the effectiveness of the equipment. This paper aims to identify the various factors and problems affecting the productivity of underground coal mines adopting the bord and pillar method of mining and to propose suitable measures for improving them. The various key factors affecting productivity, namely the cycle of operations, manpower deployment, machine efficiency, material handling and management of manpower are discussed. In addition, the problem of side discharge loader (SDL cable handling resulting in the wastage of precious manpower resources and SDL breakdown have also been identified and resolved in this paper.

    Prescription drugs have reduced morbidity and mortality and improved the quality of life of millions of Americans. Yet, concerns over drug price increases loom. Drug spending has risen relatively slowly over the past decade because many of the most popular brand-name medicines lost patent protection. In the near future, there will be fewer low-cost generics coming into the market to offset the rising prices of brand-name drugs. Drug expenditures are influenced by both volume and price. This article focuses on how drug prices are set in the United States and current trends. Drug prices are determined through an extremely complicated set of interactions between pharmaceutical manufacturers, wholesalers, retailers, insurers, pharmacy benefit managers (PBMs), managed care organizations, hospitals, chain stores, and consumers. The process differs depending on the type of drug and place of delivery. Rising drug prices have come under increased scrutiny due to increased cost inflation and because many price increases come as a result of mergers and acquisitions of generic drug companies or changes in ownership of brand name drug manufacturers. Other countries have reigned in drug prices by negotiating with or regulating pharmaceutical manufacturers. The best long-term solution to rising drug prices is yet to be determined but the United States will continue to debate this issue and the discussions will get more heated if drug expenditures continue to rise at a rapid rate (ie, increasing 13% in 2014 from the previous year).

    In 2010, the NEA in conjunction with the International Energy Agency produced an analysis of the Projected Costs of Electricity for almost 200 power plants, covering nuclear, fossil fuel and renewable electricity generation. That analysis used lifetime costs to consider the merits of each technology. However, the lifetime cost analysis is less applicable in liberalised markets and does not look specifically at the viewpoint of the private investor. A follow-up NEA assessment of the competitiveness of nuclear energy against coal- and gas-fired generation under carbon pricing has considered just this question. The economic competition in electricity markets is today between nuclear energy and gas-fired power generation, with coal-fired power generation not being competitive as soon as even modest carbon pricing is introduced. Whether nuclear energy or natural gas comes out ahead in their competition depends on a number of assumptions, which, while all entirely reasonable, yield very different outcomes. The analysis in this study has been developed on the basis of daily data from European power markets over the last five-year period. Three different methodologies, a Profit Analysis looking at historic returns over the past five years, an Investment Analysis projecting the conditions of the past five years over the lifetime of plants and a Carbon Tax Analysis (differentiating the Investment Analysis for different carbon prices) look at the issue of competitiveness from different angles. They show that the competitiveness of nuclear energy depends on a number of variables which in different configurations determine whether electricity produced from nuclear power or from CCGTs generates higher profits for its investors. These are overnight costs, financing costs, gas prices, carbon prices, profit margins (or mark-ups), the amount of coal with carbon capture and electricity prices. This paper will present the outcomes of the analysis in the context of a liberalised

  3. International coal trade: the evolution of a global market

    International Nuclear Information System (INIS)

    1998-01-01

    The international coal market has developed over the last 25 years to a mature stable market, largely free of government involvement. It is evident, however, that while the coal market is considered widely to be reliable and mature, there is only limited understanding of the way in which the market operates. Understanding energy market mechanisms is fundamental to encourage confidence in the continuing performance of liberalized markets. This publication seeks to address this need by providing a brief descriptive analysis of the operation of the coal market. The report draws attention to the considerable changes that have been experienced to date in the market, where freely operating market mechanisms have coped well. Further change is on the horizon. Coal demand in Europe is stagnating while growing rapidly in Asia. The once-dominant European market remains the region where price is formed but the Asian market is growing rapidly and becoming more flexible. Increasing competition for market share, low margins, and pressure on utilities to reduce costs as electricity markets are liberalized, will continue to stimulate productivity improvement and may lead to innovations in marketing to cope with stable real prices, high transport, and transaction costs

    To study the effect of air-coal and oxy-coal combustion on mercury emission, Xuzhou bituminous coal was burnt in a 6 kWth fluidized bed at 800 and 850 C in four atmospheres: air, 21%O{sub 2}/79%CO{sub 2}, 30%O{sub 2}/70%CO{sub 2}, 40%O{sub 2}/60%CO{sub 2} analysed with an online flue gas analyzer. Ontario Hydro method (OHM) was employed to measure mercury speciation in flue gas. The result indicated that more elemental mercury and oxidized mercury are released when burned in O{sub 2}/CO{sub 2} atmosphere than in air at 800 C, while the situation is just opposite, when coal was burnt at 850 C, less Hg{sup 0} and Hg{sup 2+} in O{sub 2}/CO{sub 2} atmosphere than in air. The concentration of Hg{sup 0} rises as temperature increases both in the conditions of the air combustion and oxy-coal combustion, but the concentration of Hg{sup 2+} increases with the increase of temperature only in the condition of air combustion and decreases in the oxy-coal combustion. With the increase of the oxygen concentration which is in the range of 21-40%, the concentrations of Hg{sup 0} and Hg{sup 2+} decrease first and then increase. When excess air coefficient increases, the oxygen content is higher and the vaporization rate of Hg{sup 0} and Hg{sup 2+} decrease.

  5. Non-competitive market behaviour in the international coking coal market

    1999-01-01

    In this paper, a primal dual programming model of international coking coal trade is constructed to test for non-competitive market behaviour. World trade in 1996 is simulated under perfect competition and various non-competitive market structures. Statistical tests are used to compare simulated trade flows with actual data. Assuming Cournot-Nash behaviour, an all consumer oligopsony market structure is preferred to alternative models. Under an all consumer oligopsony world coking coal prices and trade are lower than under perfect competition. Under an oligopsonistic structure welfare gains from productivity increases in Australian coal mines might largely accrue to coal buyers

    The program of the above clean coal technology (CCT) event is composed of 1) Coal energy be friendly toward the earth, 2) Research on CCT in America (study of coal structure under electron microscope), and 3) Research on CCT in Australia (high intensity combustion of ultrafine coal particles in a clean way). Remarks under item 1) are mentioned below. As for SO{sub 2} emissions base unit, Japan's is 1 at its coal-fired thermal power station while that of America is 7.8. As for the level of SO{sub 2}/NOx reduction attributable to coal utilization technologies, it rises in the order of flue gas desulfurizer-aided pulverized coal combustion, normal pressure fluidized bed combustion, pressurized fluidized bed combustion, integrated coal gasification combined cycle power generation, and integrated coal gasification combined cycle power generation/fuel cell. As for the level of CO2 reduction attributable to power generation efficiency improvement, provided that Japan's average power generation efficiency is 39% and if China's efficiency which is now 28% is improved to be similar to that of Japan, there will be a 40% reduction in CO2 emissions. Under item 2) which involves America's CCT program, reference is made to efforts at eliminating unnecessary part from the catalytic process and at reducing surplus air, to the export of CCT technology, and so forth. Under item 3), it is stated that coal cleaning may govern reaction efficiency in a process of burning coal particles for gasification. (NEDO)

  8. Optimal pricing and investment in the electricity sector in Tamil Nadu, India

    2001-07-01

    Faulty pricing policies and inadequate investment in the power sector are responsible for the chronic power shortages that plague Tamil Nadu and the rest of India. Formulae for optimal pricing rules are derived for a social welfare maximizing Electricity Board which sells electricity that is used both as an intermediate, and as a final good. Because of distributional constraints, the optimal prices deviate systematically from marginal costs. Optimal relative price-marginal cost differentials are computed for Tamil Nadu, and are found to indicate a lower degree of subsidization than the prevailing prices. The rationalization of electricity tariffs would very likely increase the Board's revenues. The cost-effectiveness of nuclear power in India is examined by comparing actual data for the Madras Atomic Power Project and the Singrauli coal-fired thermal power station. The conventional (non-environmental) costs of power generation are compared at both market prices and shadow prices, calculated according to the UNIDO guidelines for project evaluation. Despite favorable assumptions for the costs of the nuclear plant, coal had a decided edge over nuclear in Tamil Nadu. Remarkably, the edge varied little when market prices are replaced by shadow prices in the computations. With regard to the environmental costs, far too much remains unknown. More research is therefore needed on the environmental impacts of both types of power generation before a final choice can be made.

    Clean Air Capital Markets, an investment bank structuring SO 2 Allowance transactions, has designed two allowance value models. The first forecasts an equilibrium allowance value based on coal supply and demand. The second estimates the sulfur premium of all reported coal deliveries to utilities. Both models demonstrate that the fundamental allowance value is approximately double current spot market prices for small volumes of off-system allowances

    A consensus that the world oil market is unified begs the question, where do innovations in oil prices enter the market? Here we investigate where changes in the price of crude oil originate and how they spread by examining causal relationships among prices for crude oils from North America, Europe, Africa, and the Middle East on both spot and futures markets. Results indicate that innovations first appear in spot prices for Dubai-Fateh and spread to other spot and futures prices while other innovations first appear in the far month contract for West Texas Intermediate and spread to other exchanges and contracts. Links between spot and futures markets are relatively weak and this may have allowed the long-run relationship between spot and future prices to change after September 2004. Together, these results suggest that market fundamentals initiated a long-term increase in oil prices that was exacerbated by speculators, who recognized an increase in the probability that oil prices would rise over time.

    This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken using monthly data from January 2000 to August 2011. The results suggest nonstationary long memory in the series (with orders of integration equal to or higher than 1) when breaks are not allowed for. However, endogenous break tests indicate a single break in all series except for producer prices for lignite for which two breaks are detected. When such breaks are taken into account, and with autocorrelated disturbances, evidence of mean reversion is found in practically all cases.

  12. Influence of gender roles and rising food prices on poor, pregnant women’s eating and food provisioning practices in Dhaka, Bangladesh

    Science.gov (United States)

    2013-01-01

    Background Maternal malnutrition in Bangladesh is a persistent health issue and is the product of a number of complex factors, including adherence to food 'taboos’ and a patriarchal gender order that limits women’s mobility and decision-making. The recent global food price crisis is also negatively impacting poor pregnant women’s access to food. It is believed that those who are most acutely affected by rising food prices are the urban poor. While there is an abundance of useful quantitative research centered on maternal nutrition and food insecurity measurements in Bangladesh, missing is an understanding of how food insecurity is experienced by people who are most vulnerable, the urban ultra-poor. In particular, little is known of the lived experience of food insecurity among pregnant women in this context. This research investigated these lived experiences by exploring food provisioning strategies of urban, ultra-poor, pregnant women. This knowledge is important as discussions surrounding the creation of new development goals are currently underway. Methods Using a focused-ethnographic approach, household food provisioning experiences were explored. Data from participant observation, a focus group discussion and semi-structured interviews were collected in an urban slum in Dhaka, Bangladesh. Interviews were undertaken with 28 participants including 12 pregnant women and new mothers, two husbands, nine non-pregnant women, and five health care workers. Results The key findings are: 1) women were aware of the importance of good nutrition and demonstrated accurate, biomedically-based knowledge of healthy eating practices during pregnancy; 2) the normative gender rules that have traditionally constrained women’s access to nutritional resources are relaxing in the urban setting; however 3) women are challenged in accessing adequate quality and quantities of food due to the increase in food prices at the market. Conclusions Rising food prices and resultant food

    In competitive product markets, repeated interaction among producers with similar economic characteristics would be expected to result in convergence of their behaviors. If convergence does not occur, it raises fundamental questions related to the sustainability of heterogeneous competitive strategies. This paper examines the prices submitted to the British wholesale electricity market by four coal-fired plants, separately owned, approximately of the same age, size and efficiency, and located in the same transmission network zone. Due to the repetitive nature of the spot market, one would expect convergence in strategies. Yet, we find evidence of persistent price dispersion and heterogeneous strategies. We consider several propositions for these effects including market power, company size, forward commitments, vertical integration and the management of interrelated assets. - Highlights: • Time series models of offer prices from 4 companies, UK electricity spot market • Focus on coal-fired plants of similar size, efficiency, age, same network zone • Low, less volatile offers by small, not vertically integrated, only-coal company • Operational risks of nuclear plants in a portfolio imply finer tracking of PX prices • Market leadership from private information on the Anglo-French interconnector flows

  14. Coal supply shortage - buyers beware

    1988-08-01

    Since the commencement of 1988, the world coal market has witnessed a number of quite remarkable shifts and realignments that have ostensibly resulted from import demand surges, notably in Europe and the Pacific Rim but perhaps more significantly also from constraints on supply, most obviously in Australia but also seen elsewhere in the PRC, Colombia, Poland, and South Africa. Consequently, this has left the USA as the only remaining reliable surplus supplier of high volume quality steam and metallurgical coals to the world market. Importantly, it has to be recognised that these existing supply/demand factors will not disappear overnight. What has been a very strong buyers' market for coal throughout at least the last six years is now no longer the case. Coal purchasers around the globe have to be prepared for an extended and indeed a refreshing period of 'seller power' with scarcity of supply and higher coal prices forecast to extend well into next year and maybe even longer. The message for coal importers who have not yet woken up to the new order of things is very clear, 'today is possibly already too late to secure coal purchases for delivery in 1988 because many exporters report they are sold out. But more important with tight supply expected to prevail, buyers should be securing their purchases now for 1989 imports requirements and delivery'. 2 figs.

    2010-01-01

    This paper discusses and quantifies the so-called loss of profit (i.e., the sub-optimality of profit) that can be expected in a Price Based Unit Commitment (PBUC), when incorrect price forecasts are used. For this purpose, a PBUC model has been developed and utilized, using Mixed Integer Linear Programming (MILP). Simulations are used to determine the relationship between the Mean Absolute Percentage Error (MAPE) of a certain price forecast and the loss of profit, for four different types of power plants. A Combined Cycle (CC) power plant and a pumped storage unit show highest sensitivity to incorrect forecasts. A price forecast with a MAPE of 15%, on average, yields 13.8% and 12.1% profit loss, respectively. A classic thermal power plant (coal fired) and cascade hydro unit are less affected by incorrect forecasts, with only 2.4% and 2.0% profit loss, respectively, at the same price forecast MAPE. This paper further demonstrates that if price forecasts show an average bias (upward or downward), using the MAPE as measure of the price forecast might not be sufficient to quantify profit loss properly. Profit loss in this case has been determined as a function of both shift and MAPE of the price forecast. (author)

    1993-01-01

    The expected price of SO 2 emission allowances is an important issue in energy and integrated resource planning activities. For example, the expected price of SO 2 allowances in needed in order to evaluate alternative strategies for meeting SO 2 provisions of the Clean Air Act Amendments of 1990. In addition, the expected SO 2 allowance price is important to state public utility regulators who must provide guidance on rate-making issues regarding utility compliance plans which involve allowance trading and direct investment of SO 2 control technologies. Last but not the least, the expected SO 2 allowance price is an important determinant of the future market for natural gas and low sulfur coal. The paper develops estimates of SO 2 allowance prices over time by constructing national supply and demand curves for SO 2 reductions. Both the supply and demand for SO 2 reductions are based on an analysis of the sulfur content of fuels burned in 1990 by utilities throughout the United States; and on assumptions about plant retirements, the rate of new capacity growth, the types of new and replacement plants constructed, the costs of SO 2 reduction measures and legislation by midwest states to maintain the use of high sulfur coal to protect local jobs. The paper shows that SO 2 allowance prices will peak around the year 2000 at about $500 per ton, and will eventually fall to zero by about the year 2020. A sensitivity analysis indicates that the price of SO 2 allowances is relatively insensitive to assumptions regarding the availability of natural gas or energy demand growth. However, SO 2 allowance prices tend to be quite sensitive to assumptions regarding regulations which may force early retirement of existing power plants and possible legislation which may reduce CO 2 emissions

    1998-01-01

    The position of coal as the preferred fossil fuel for power generation is being challenged by gas. The total cost of production in $/kW/annum of coal generation compared with combined cycle gas turbine plant is illustrated for a range of annual capacity factors and fuel costs in the Australian context. lt is shown that plant capacity factors over 80%are required for coal-fired plants to be price competitive with gas. Unlike other fossil fuel energy types, the high capital cost of coal-fired plant means that new coal-fired plant will generally need to be base-loaded throughout their operating life to be competitive. However, experience shows that having installed the plant, it will operate as base-loaded, intermediate or peaking duty depending on market circumstances. Existing plants In New South Wales, Victoria and Queensland are generally operating at annual capacity factors that are below optimum levels. It is concluded that the coal-fired energy industry can be strongly challenged for the foreseeable future

    2018-01-01

    Full Text Available A coal burst mitigation strategy for tailgate in mining of deep inclined longwall panels with top coal caving at Huafeng Coal Mine is presented in this paper. Field data showed that coal bursts, rib sloughing or slabbing, large convergence, and so forth frequently occurred within the tailgate entries during development and panel retreating employing standard longwall top coal caving (LTCC layout which resulted in fatal injuries and tremendous profit loss. The contributing factors leading to coal bursts were analyzed. Laboratory tests, in situ measurement, and field observation demonstrate that the intrinsic bursting proneness of the coal seam and immediate roof stratum, deep cover, overlying ultrathick (500–800 m conglomerate strata, faults, and, most importantly, improper panel layout led to coal bursts. By employing a new strategy, that is, longwall mining with split-level gateroads (LMSG, gateroads on either end of a LMSG panel are located at different levels within a coal seam, adjacent LMSG panels overlap end to end, and the tailgate of the adjacent new LMSG panel can be located below the headgate entry of the previous LMSG panel or may be offset horizontally with respect to it. Numerical modeling was carried out to investigate the stress distribution and yield zone development within surrounding rock mass which was validated by field investigation. The results indicate that standard LTCC system gave rise to high ground pressure around tailgate entries next to the gob, while LMSG tailgate entry below the gob edge was in a destressed environment. Therefore, coal bursts are significantly mitigated. Field practice of LMSG at Huafeng Coal Mine demonstrates how the new strategy effectively dealt with coal burst problems in mining of deep inclined longwall panels with a reduced incidence of ground control problems. The new strategy can potentially be applied in similar settings.

    The thesis comprises four interrelated essays featuring modelling and analysis of coal markets. Each of the four essays has a dedicated chapter in this thesis. Chapters 2 to 4 have, from a topical perspective, a backward-looking focus and deal with explaining recent market outcomes in the international coal trade. The findings of those essays may serve as guidance for assessing current coal market outcomes as well as expected market outcomes in the near to medium-term future. Chapter 5 has a forward-looking focus and builds a bridge between explaining recent market outcomes and projecting long-term market equilibria. Chapter 2, Strategic Behaviour in International Metallurgical Coal Markets, deals with market conduct of large exporters in the market of coals used in steel-making in the period 2008 to 2010. In this essay I analyse whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models - a Stackelberg model, two varieties of a Cournot model, and a perfect competition model - for computing spatial equilibria in international resource markets. Results are analysed with various statistical measures to assess the prediction accuracy of the models. The results show that real market equilibria cannot be reproduced with a competitive model. However, real market outcomes can be accurately simulated with the non-competitive models, suggesting that market equilibria in the international metallurgical coal trade were subject to the strategic behaviour of coal exporters. Chapter 3 and chapter 4 deal with market power issues in the steam coal trade in the period 2006 to 2008. Steam coals are typically used to produce steam either for electricity generation or for heating purposes. In Chapter 3 we analyse market behaviour of key exporting countries in the steam coal trade.

  2. OPEC's optimal crude oil price

    International Nuclear Information System (INIS)

    Horn, Manfred

    2004-01-01

    OPEC decided to stabilise oil prices within a range of 22-28 US Dollar/barrel of crude oil. Such an oil-price-level is far beyond the short and long run marginal costs of oil production, beyond even that in regions with particularly high costs. Nevertheless, OPEC may achieve its goal if world demand for oil increases substantially in the future and oil resources outside the OPEC are not big enough to accordingly increase production. In this case OPEC, which controls about 78% of world oil reserves, has to supply a large share of that demand increase. If we assume OPEC will behave as a partial monopolist on the oil market, which takes into consideration the reaction of the other producers to its own sales strategy, it can reach its price target. Lower prices before 2020 are probable only if the OPEC cartel breaks up. Higher prices are possible if production outside OPEC is inelastic as assumed by some geologists, but they would probably stimulate the production of unconventional oil based on oil sand or coal. Crude oil prices above 30 US Dollar/barrel are therefore probably not sustainable for a long period. (Author)

  3. Oil Price and Economic Resilience. Romania’s Case

    Full Text Available The emerging economies that do not face fiscal, monetary and foreign debt pressures can use the savings generated by lower oil prices for investments in order to generate economic growth. Hence, there is no doubt that the oil price affects the economy’s resilience to shocks. The importance of this impact derives from the magnitude of the price change and its diffusion within the economy. Moreover, the sustainability of any company and of the economy as a whole is subject to the availability and the price of the energy resources. The cost of these resources is an important variable used in the majority of the models regarding the assessment of sustainable development. Therefore, this article examines the impact of the oil price changes on industrial production in Romania. We found that, similar to other countries, in Romania, the growth rate of industrial production responds more strongly to a rise in oil prices. Thus, the oil Brent price has an asymmetric effect on the production evolution. This finding suggests that macroeconomic stabilization is more difficult to achieve when the oil price rises.

    UK ports and rail operators have invested heavily to improve available capacity, but now imports are leveling off. In January to May 2007, UK coal imports totalled 19.2 mt, a drop of 6% compared to the same period in 2006. Indigenous production dropped more drastically, 23.8% to 6.62 mt. UK coal demand will be determined by such factors as the Large Combustion Plant Directive. There appears to be a second wave in the 'dash for gas' generation game as gas prices have fallen. Investment at Immingham's terminal has enabled the UK to cope with increased coal imports. ABP is now considering another coal terminal outside the locks at Hull. These plans are outlined in the article. Coal handling at Newcastle is also reported. 3 figs., 1 photos.

  5. Economics of the coal industry east of the Mississippi, 1973-1982

    Government regulations on health, safety and environment have been poppular blamed for the declining productivity in U.S. coal mines since 1970. The stagnation in the coal industry east of the Mississippi is alleged to have been caused by this declining productivity and by the growth of cheaper and cleaner coal production west of the Mississippi. Economic evidence suggests, however, that productivity declines were more due to a relative lowering of labor costs in comparison with coal prices and due to work stoppages. The development of western coals fields was spurred by growth in local demand and had only a relatively small impact on coal production east of the Mississippi. Problems of the eastern coal industry are rooted mainly in slow economic growth in eastern U.S. which must be addressed in the long-term interests of the eastern coal industry. ?? 1987.

    Highlights: • The potential for the first 10 MWe level solar–coal hybrid power plant is estimated. • Economic feasibility analysis is performed based on the discounted cash flow model. • The appropriate feed-in tariff prices of different scenarios are provided. • The results provide suggestions for the development of solar–coal hybrid technology. - Abstract: Middle-temperature solar heat can be used to preheat feed water before it enters the boiler in a coal-fired power plant. Previous studies have shown that this approach can improve the performance of coal-fired power plants. The present study estimates the first solar–coal hybrid power plant in the Inner Mongolia Region. It will have a potential net solar power output of 10 MW on the basis of the operating data of a traditional 200 MW coal-fired power plant. Economic feasibility analysis is then performed on the solar–coal hybrid power plant. The appropriate feed-in tariff prices are provided on the basis of different financing scenarios, solar field cost, collector area size, and other conditions. The results obtained in this study are expected to provide suggestions for the further development of solar–coal hybrid technology.

    Full Text Available The paper analyses the association between certain macroeconomic variables and food price inflation, non-food price inflation and overall inflation in Zimbabwe, and also seeks to determine the level of association between these variables, given food security implications and overall well-being of its citizens. The study reveals that during the 2010 to 2016 period, Zimbabwe experienced stable food prices—annual food price inflation for food and non-alcoholic beverages averaged a relatively low growth rate of 0.12% monthly, while non-food inflation monthly growth rate was 0.09% and overall inflation growth rate was 0.11%. Although inflation from 2010 had been declining, of late, the increase in annual inflation has been underpinned by a rise in non-food inflation. Zimbabwe’s annual inflation remains lower than inflation rates in other countries in the region. Despite the increases lately in overall inflation, it remained below zero in January 2016, mostly driven by the depreciation of the South African rand and declining international oil prices. It should also be noted that domestic demand continued to decline in 2015, leading to the observed decline in both food and non-food prices. While food inflation has remained relatively low, it should be noted that non-food expenditures is significant component of the household budget and the rising prices result often lead to declining purchasing power and force households to make difficult choices in terms of their purchases. The findings of the study are food inflation has a low association with the independent variables under study; Zimbabwe broad money supply, rand-dollar exchange rates and the South Africa food inflation. There is, however, a very strong association between non-food inflation and these independent variables, as well as between overall inflation and the independent variables. Given the mostly rural population and the high level of unemployment in Zimbabwe, it can be surmised that

    Husin, T. (Tenaga Nasional Berhad (Malaysia))

    1993-03-01

    This paper describes problems in coal development and coal processing techniques used in Malaysia. Malaysia has a national organization placing importance on maximizing natural gas source development, but no such an organization is available for coal. Necessity exists in developing transportation infrastructures that can transport coal at a competitive price from coal mines to users inside and outside the country. Majority of the Merit Pila coal is produced in mines with relatively thin coal beds, which raise production cost higher. Coal resources are mostly of low calorific power. Since the coal resource development is a new economic activity, it requires training of people in related areas, and frameworks of legislative regulation. Important in coal development is to select technologies that can meet environmental requirements and stand with competitions in the world coal markets. New coal processing technologies available for discussion in coal refining processes include relaxed gasification or pyrolysis, coal liquefaction, coal-water mixture to mix coal powder and water with additives, coal pretreatment techniques, coal cleaning techniques, and fluidized bed combustion. 1 fig., 1 tab.

    The relationships between changes in food sector input costs and retail food prices are examined. Results indicate that increases in factor prices pass quickly to consumers, within two quarters for most foods. In addition, rising farm-level prices and substantial increases in nonfarm resource prices appear to explain why food prices rose more rapidly than nonfood prices in the 1970s. The analysis is based on a twenty-equation econometric model of the food-price determination process, specifie...

    The reducing coal market has been enforcing the coal industry to make exceptional rationalization and restructuring efforts since the end of the eighties. To the competition from crude oil and natural gas has been added the growing pressure from rising wages and rising production cost as the working get deeper. To improve the competitive position of the remaining 11 coal mines after the rationalization of the industry, studies to improve mining system have been carried out. This report consists of 3 subjects. 1) Designing of the bord and pillar mining method to extract gently inclined seams of the Dogye coal mine. 2) Mechanization of coal cutting by plough. 3) Achievement of the mechanization of coal mining compared to the previous year.

    2014-01-01

    Carbon Capture and Storage is considered as a key option for climate change mitigation; policy makers and investors need to know when CCS becomes economically attractive. Integrating CCS in a power plant adds significant costs which can be offset by a sufficient CO 2 price. However, most markets have failed: currently, the weak carbon price threatens CCS deployment in the European Union (EU). In China, a carbon regulation is appearing and CCS encounters a rising interest. This study investigates two questions: how much is the extra-cost of a CCS plant in the EU in comparison with China? Second, what is the CO 2 price beyond which CCS plants become more profitable than reference plants in the EU and in China? To address these issues, I conducted a literature review on public studies about CCS costs. To objectively assess the profitability of CCS plants, I constructed a net present value model to calculate the Levelised Cost of Electricity and the breakeven CO 2 price. CCS plants become the most profitable plant type beyond 115 €/tCO 2 in the EU vs. 45 €/tCO 2 in China (offshore transport and storage costs). I advise on the optimal plant type choice depending on the CO 2 price in both countries. - Highlights: • I develop a method to objectively update and compare CCS costs in the EU and China. • To represent investment choices, intra and inter CO 2 switching prices are required. • EU CCS plants are profitable for a CO 2 price higher than 115 €/t (offshore storage). • Chinese CCS plants are profitable beyond 45 €/tCO 2 (35 €/tCO 2 with onshore storage). • With 2030 projections, CCS (coal) plants are profitable in China but not in the EU

    Full Text Available The international crude oil prices started the year 2014 within parameters comparable to those of the precedent year: WTI (USA recorded 92 $/barrel, on the American spot market, considered a minimum value for the last 5 weeks, while Brent (Great Britain had a more stable evolution, on the spot Rotterdam market, staying around a value of 107,50 $/barrel. Despite analysts’ forecasts, which during the last 3 years staked on a lower oil price, as a consequence of the spectacular increase in non-OPEC oil production, namely of shale oil, the international oil price, namely that of Brent, closed each of the last 3 years around the same level, of 108 $/barrel. As for 2014, the great majority of oil analysts estimates again a decline of oil prices, as a result of a significant rise of oil offer globally, which will greatly surpass the demand rise.

    2009-07-15

    Coal fuels more than 30 per cent of UK electricity production, and about 50 per cent in the US, providing a significant portion of total energy output. China and India's recent ferocious economic growth has been based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging us full steam ahead, the increasing reliance on this dirtiest of all fossil fuels has crucial implications for energy policy, pollution levels, the global climate, world economy and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity - new studies suggest that the peak of world coal production may actually be less than two decades away; Cost - the quality of produced coal is declining, while the expense of transportation is rising, leading to spiralling costs and increasing shortages; and, Climate impacts - our ability to deal with the historic challenge of climate change may hinge on reducing coal consumption in future years.

    Uranium producers came alive in August, helping spot prices crack the $8.00 barrier for the first time since March. The upper end of NUKEM's price range actually finished the month at $8.20. Scrambling to fulfill their long-term delivery contracts, producers dominate the market. In the span of three weeks, five producers came out for 2 million lbs U3O8, ultimately buying nearly 1.5 million lbs. One producer accounted for over half this volume. The major factor behind rising prices was that producers required specific origins to meet contract obligations. Buyers willing to accept open origins created the lower end of NUKEM's price range

    Highlights: • Present the opportunities and challenges of coal-to-olefins (CTO) development. • Conduct a techno-economic analysis on CTO compared with oil-to-olefins (OTO). • Suggest approaches for improving energy efficiency and economic performance of CTO. • Analyze effects of plant scale, feedstock price, CO 2 tax on CTO and OTO. - Abstract: Olefins are one of the most important oil derivatives widely used in industry. To reduce the dependence of olefins industry on oil, China is increasing the production of olefins from alternative energy resources, especially from coal. This study is concerned with the opportunities and obstacles of coal-to-olefins development, and focuses on making an overall techno-economic analysis of a coal-to-olefins plant with the capacity of 0.7 Mt/a olefins. Comparison is made with a 1.5 Mt/a oil-to-olefins plant based on three criteria including energy efficiency, capital investment, and product cost. It was found that the coal-based olefins process show prominent advantage in product cost because of the low price of its feedstock. However, it suffers from the limitations of higher capital investment, lower energy efficiency, and higher emissions. The effects of production scale, raw material price, and carbon tax were varied for the two production routes, and thus the operational regions were found for the coal-to-olefins process to be competitive

    The Department of Energy`s clean coal technology (CCT) program succeeded in developing more efficient, cleaner, coal-fired electricity options. The Department and its private partners succeeded in the demonstration of CCT -- a major feat that required more than a decade of commitment between them. As with many large-scale capital developments and changes, the market can shift dramatically over the course of the development process. The CCT program was undertaken in an era of unstable oil and gas prices, concern over acid rain, and guaranteed markets for power suppliers. Regulations, fuel prices, emergency of competing technologies, and institutional factors are all affecting the outlook for CCT deployment. The authors identify the major barriers to CCT deployment and then introduce some possible means to surmount the barriers.

  3. Phosphate rock costs, prices and resources interaction.

    This article gives the author's views and opinions as someone who has spent his working life analyzing the international phosphate sector as an independent consultant. His career spanned two price hike events in the mid-1970's and in 2008, both of which sparked considerable popular and academic interest concerning adequacy of phosphate rock resources, the impact of rising mining costs and the ability of mankind to feed future populations. An analysis of phosphate rock production costs derived from two major industry studies performed in 1983 and 2013 shows that in nominal terms, global average cash production costs increased by 27% to $38 per tonne fob mine in the 30 year period. In real terms, the global average cost of production has fallen. Despite the lack of upward pressure from increasing costs, phosphate rock market prices have shown two major spikes in the 30 years to 2013, with periods of less volatility in between. These price spike events can be seen to be related to the escalating investment cost required by new mine capacity, and as such can be expected to be repeated in future. As such, phosphate rock price volatility is likely to have more impact on food prices than rising phosphate rock production costs. However, as mining costs rise, recycling of P will also become increasingly driven by economics rather than legislation. Copyright © 2015 Elsevier B.V. All rights reserved.

    To quantify the relation between food prices and the demand for food with specific reference to national and household income levels. Systematic review with meta-regression. Online databases of peer reviewed and grey literature (ISI Web of Science, EconLit, PubMed, Medline, AgEcon, Agricola, Google, Google Scholar, IdeasREPEC, Eldis, USAID, United Nations Food and Agriculture Organization, World Bank, International Food Policy Research Institute), hand searched reference lists, and contact with authors. We included cross sectional, cohort, experimental, and quasi-experimental studies with English abstracts. Eligible studies used nationally representative data from 1990 onwards derived from national aggregate data sources, household surveys, or supermarket and home scanners. The primary outcome extracted from relevant papers was the quantification of the demand for foods in response to changes in food price (own price food elasticities). Descriptive and study design variables were extracted for use as covariates in analysis. We conducted meta-regressions to assess the effect of income levels between and within countries on the strength of the relation between food price and demand, and predicted price elasticities adjusted for differences across studies. 136 studies reporting 3495 own price food elasticities from 162 different countries were identified. Our models predict that increases in the price of all foods result in greater reductions in food consumption in poor countries: in low and high income countries, respectively, a 1% increase in the price of cereals results in reductions in consumption of 0.61% (95% confidence interval 0.56% to 0.66%) and 0.43% (0.36% to 0.48%), and a 1% increase in the price of meat results in reductions in consumption of 0.78% (0.73% to 0.83%) and 0.60% (0.54% to 0.66%). Within all countries, our models predict that poorer households will be the most adversely affected by increases in food prices. Changes in global food prices will

    The United States produced just over 1 billion short tons of coal in 1992, 0.4 percent more than in 1991. Most of the 4-million-short-ton increase in coal production occurred west of the Mississippi River, where a record level of 408 million short tons of coal was produced. The amount of coal received by domestic consumers in 1992 totaled 887 million short tons. This was 7 million short tons more than in 1991, primarily due to increased coal demand from electric utilities. The average price of delivered coal to each sector declined by about 2 percent. Coal consumption in 1992 was 893 million short tons, only 1 percent higher than in 1991, due primarily to a 1-percent increase in consumption at electric utility plants. Consumer coal stocks at the end of 1992 were 163 million short tons, a decrease of 3 percent from the level at the end of 1991, and the lowest year-end level since 1989. US coal exports fell 6 percent from the 1991 level to 103 million short tons in 1992. Less coal was exported to markets in Europe, Asia, and South America, but coal exports to Canada increased 4 million short tons

    A drop-tube Furnace simulation model has been developed to investigate the pulverized coal combustion characteristics under different altitudes using the commercially available software Fluent. The altitude conditions of 0, 500, 1,000, 1,500 m have been discussed. The results included the fields of temperature, pressure, velocity, the coal burnout, CO burnout and NO emission in the tube furnace. The variation of these parameters with altitude has been analyzed. The coal combustion characteristics were affected by the altitude. The time and space for coal burnout should be increased with the rise of altitude. The valuable results could be referenced in the design of coal- fired furnaces for the high altitude areas.

    The aim of this work was to carry out a geochemical study of channel samples collected from six coal beds in the Marcelina Formation (Zulia State, western Venezuela) and to determine experimentally the gas content of the coals from the Paso Diablo mine. Organic geochemical analyses by gas chromatography-mass spectrometry and isotopic analyses on-line in coalbed gas samples were performed. The results suggest that the Guasare coals were deposited in a continental environment under highly dysoxic and low salinity conditions. The non-detection of 18??(H)-oleanane does not preclude that the organic facies that gave rise to the coals were dominated by angiosperms. In addition, the presence of the sesquiterpenoid cadalene may indicate the subordinate contribution of gymnosperms (conifers) in the Paleocene Guasare mire. The average coalbed gas content obtained was 0.6 cm3/g. ??13C and D values indicate that thermogenic gas is prevalent in the studied coals. Copyright ?? Taylor & Francis Group, LLC.

    1985-04-25

    Efforts to keep China's coal industry financially healthy and to continue increasing production also created problems in terms of output, transport, environmental damage, accidents, and labor pressures. In addition to the historical and economic reasons for these pressures, inadequate leadership and policy errors made things worse. An analysis suggests three problems: (1) an inequitable division of duties between government and business, (2) a neglected marketplace, and (3) the dominance of egalitarianism. The report relates these problems to the production of coal and a package of reforms which restructured the economic system of the industry to give it more autonomy and economic responsibility. The reforms emphasize rational pricing and use of coal as well as management of the industry.

    Wals, A.F.; Hobbs, B.F.; Rijkers, F.A.M.

    2004-05-01

    The conjectured transmission price response model presented in the first of this two-paper series considers the expectations of oligopolistic generators regarding how demands for transmission services affect the prices of those services. Here, the model is applied to northwest Europe, simulating a mixed transmission pricing system including export fees, a path-based auction system for between-country interfaces, and implicit congestion-based pricing of internal country constraints. The path-based system does not give credit for counterflows when calculating export capability. The application shows that this no-netting policy can exacerbate the economic inefficiencies caused by oligopolistic pricing by generators. The application also illustrates the effects of different generator conjectures regarding rival supply responses and transmission prices. If generators anticipate that their increased demand for transmission services will increase transmission prices, then competitive intensity diminishes and energy prices rise. In the example here, the effect of this anticipation is to double the price increase that results from oligopolistic (Cournot) competition among generators

  11. Cost-reflective electricity pricing: Consumer preferences and perceptions

    In Australia, residential electricity peak demand has risen steeply in recent decades, leading to higher prices as new infrastructure was needed to satisfy demand. One way of limiting further infrastructure-induced retail price rises is via ‘cost-reflective’ electricity network pricing that incentivises users to shift their demand to non-peak periods. Empowering consumers with knowledge of their energy usage is critical to maximise the potential benefits of cost-reflective pricing. This research consulted residential electricity consumers in three Australian states on their perceptions and acceptance of two cost-reflective pricing scenarios (Time-of-Use and Peak Capacity pricing) and associated technologies to support such pricing (smart meters, in-home displays and direct load control devices). An energy economist presented information to focus groups on the merits and limitations of each scenario, and participants’ views were captured. Almost half of the 53 participants were agreeable to Time-of-Use pricing, but did not have a clear preference for Peak Capacity pricing, where the price was based on the daily maximum demand. Participants recommended further information to both understand and justify the potential benefits, and for technologies to be introduced to enhance the pricing options. The results have implications for utilities and providers who seek to reduce peak demand. - Highlights: •Electricity price rises can be limited by ‘cost-reflective’ pricing. •We consulted residential electricity consumers on Time-of-Use and Peak Capacity pricing. •Understanding of peak electricity demand must increase to enable demand shift. •Interactive website could enable consumers to evaluate pricing options. •Smart meter adoption may increase if voluntary and includes an in-home display.

    The literature on renewable energy suggests that an increase in intermittent wind generation would reduce the spot electricity market price by displacing high fuel-cost marginal generation. Taking advantage of a large file of Texas-based 15-min data, we show that while rising wind generation does indeed tend to reduce the level of spot prices, it is also likely to enlarge the spot-price variance. The key policy implication is that increasing use of price risk management should accompany expanded deployment of wind generation. - Highlights: → Rising wind generation in ERCOT tends to reduce electricity spot prices. → Rising wind generation in ERCOT is also likely to enlarge the spot-price variance. → Increased price risk management should accompany expanded wind power deployment.

    The State Grid Corporation of China proposes an alternative energy strategy, which will make electric heating an important task in the field of residential electricity consumption. This article takes this as the background, has made the detailed introduction to the inhabitant electric heating technology, and take the Zhangjiakou electric panels heating technology as an example, from the expense angle, has carried on the analysis to the electric panels heating economy. In the field of residential heating, electric panels operating costs less than gas boilers. After customers implying energy-saving behavior, electric panels operating cost is even lower than coal-fired boilers. The critical price is higher than the execution price, which indicates that the economic performance of the electric panels is significantly higher than that of the coal boiler.

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    There is hardly another energy resource where public opinion and reality lie as far apart as they do for coal. Many think of coal as an inefficient relic from the era of industrialisation. However, such views underestimate the significance of this energy resource both nationally and globally. In terms of global primary energy consumption coal ranks second behind crude oil, which plays a central role in the energy sector. Since global electricity use is due to rise further, coal, being the only energy resource that can meet a growing electricity demand over decades, stands at the beginning of a renaissance, and does so also in the minds of the political leadership. Coal is indispensable as a bridging technology until the electricity demand of the world population can be met primarily through renewable resources.

    During the twentieth century coal has moved from being the dominant energy hero that fueled the industrial revolution to a background role: a fuel of last choice, a supplemental resource, and sometimes a convenient villain in the environmental debate. But, as this paper points out, the other side of the coin is that coal is dependable, plentiful, and the price is right. To examine the issue as it merits, reason will have to be substituted for emotion. We are currently in what the author of this paper calls the crisis enrichment stage of the debate. In this stage, when definitive knowledge is lacking, there is a temptation to imagine the worst, overcorrect the problem, and do considerable damage to energy supply and economic needs. The environmental movement has provoked a hunt for someone to blame for the world's current environmental situation. Without a proven culprit to blame for disturbances to some of the world's lakes and forests, it has been decided that coal is the cause. This paper makes a plea for balance, urging all parties to find some acceptable middle ground between energy production and environmental protection

    Gallium is widely used in electronic industry and its current price is about 500 US dollars per kilogram. It has been found that its contents are very high in Permo-Carboniferous coal of China. In order to look for valuable associated gallium deposits in coal, gallium contents of 177 coal samples were determined by using inductively coupled plasma-mass spectrometry (ICP-MS) and the data of 873 coal samples from Chinese Permo-Carboniferous coalfields were collected. The results show that the average gallium concentration of Chinese Permo-Carboniferous coals is 15.49{mu}g{center_dot}g{sup -1}. There are two concentration types of gallium in Chinese Permo-Carboniferous coals: one type is that gallium has enriched to an ore deposit, and another type is that gallium is locally enriched in coal seams, but has not formed a valuable associated gallium ore deposit. The gallium concentration in Chinese Permo-Carboniferous coal may have several different sources: concentration in sedimentation stage, magmatic hydrothermal inputs and low-temperature hydrothermal fluids.

    The efficiency of electricity generation in hard coal fired power plants varies considerably from country to country and over time. These differences occur both between developing and developed countries and between industrialised nations. The econometric analysis presented in this paper tests for the reasons of these discrepancies. In this examination abundance of hard coal and the price of hard coal are the two variables of our major interest. We assume that countries with an abundance of h...

    The seminar held in Warsaw by the CIFOPE from 23 to 25 november 1992 was centered around the restructuring of the coal industry and its implications for the Polish economy in the context of the current deep-running economic reforms. Partly based on French experience, this seminar shed some light on long-term problems for Poland like the kind of industrial policy that will be needed to avoid desertification problems, the need for price reform in the pursuit of profitability, and the networks and financial aids needed to restructure on such a large scale, considering that coal is a key sector in the Polish economy

    Highlights: • We report a nuclear–coal hybrid energy systems. • We address the high-carbon energy resource integrating with a low-carbon energy resource. • We establish a systematic techno-economic model. • Improving both energy and carbon efficiency. • A significantly lower CO 2 emission intensity is achieved by the system. - Abstract: Global energy consumption is expected to increase significantly due to the growth of the economy and population. The utilization of fossil resource, especially coal, will likely be constrained by carbon dioxide emissions, known to be the principal contributor to climate change. Therefore, the world is facing the challenge of how to utilize fossil resource without a large carbon footprint. In the present work, a nuclear–coal hybrid energy system is proposed as a potential solution to the aforementioned challenge. A high-carbon energy such as coal is integrated effectively with a low-carbon energy such as nuclear in a flexible and optimized manner, which is able to generate the chemicals and fuels with low carbon dioxide emissions. The nuclear–coal hybrid energy system is presented in this paper for the detailed analysis. In this case, the carbon resource required by the fuel syntheses and chemical production processes is mainly provided by coal while the hydrogen resource is derived from nuclear energy. Such integration can not only lead to a good balance between carbon and hydrogen, but also improve both energy and carbon efficiencies. More importantly, a significantly lower CO 2 emission intensity is achieved. A systematic techno-economic model is established, and a scenario analysis is carried out on the hybrid system to assess the economic competitiveness based on the considerations of various types of externalities. It is found that with the rising carbon tax and coal price as well as the decreasing cost of nuclear energy, the hybrid energy system will become more and more economically competitive with the

    Data are presented on energy consumption and energy prices related to a number of OECD (Organisation for Economic Co-operation and Development) lands covering the period 1951-1990. The information sources are described and the development of energy consumption and prices in Denmark are illustrated in relation to these other countries. The energy intensity (the relation between energy consumption and the gross national product) is dealt with. Here it is possible to follow development during the whole post-war period. It is generally understood that Denmark saved large amounts of energy after 1973-74 but, taken over the whole post-war period, savings and decline in energy-gross national product relations are less dramatic compared to conditions in other OECD countries. Energy coefficients or elasticities show the relative rise in consumption compared to the relative rise in gross national product (growth rate). This is shown to be typically unstable and an eventual connection with the amount of energy price increase and/or the growth rate of the national economy is considered. Results of Granger causuality tests on energy consumption, national income and energy prices are presented. Effective energy prices were very low in Denmark up to 1970 when they suddenly began to increase. Since the oil crisis Denmark's energy consumption has fallen whereas the other countries have used rather more energy than before. Effective promotion of energy savings must be seen in relation to the fact that the 1970 basis level of energy consumption and intensity was unusually high. The high effective energy prices have also encouraged energy savings in Denmark. (AB)

    The People's Republic of China (hereafter referred to as China) is the largest producer and consumer of coal in the world. Coal makes up 76% and 74% of China's primary energy consumption and production, respectively. This heavy dependence on coal has come at a high price for China, accounting for a large share of its environmental problems. This report examines the dominance of coal in China's energy balance, its impact on the environment, and the need for technical and financial assistance, specifically for two distinct aspects: the effect of coal use on the environment and the importance of coal to China's economy. The results of the analysis are presented in two volumes. Volume 1 focuses on full fuel cycle coal emissions and the environmental effects of coal consumption. Volume 2 provides a detailed analysis by sector of China's economy and examines the economic impact of constraints on coal use. 51 refs., 19 figs., 15 tabs

    Price elasticity estimates of residential electricity demand vary widely across the energy economics and policy literature. In this paper, we seek to explain these findings using three nationwide datasets from the U.S. – the American Housing Survey, Forms EIA-861, and the Residential Energy Consumption Survey. We examine the role of the sample period, level of aggregation, use of panel data, use of instrumental variables, and inclusion of housing characteristics and capital stock. Our findings suggest that price elasticities have remained relatively constant over time. Upon splitting our panel datasets into annual cross sections, we do observe a negative relationship between price elasticities and the average price. Whether prices are rising or falling appears to have little effect on our estimates. We also find that aggregating our data can result in both higher and lower price elasticity estimates, depending on the dataset used, and that controlling for unit-level fixed effects with panel data generally results in more inelastic demand functions. Addressing the endogeneity of price and/or measurement error in price with instrumental variables has a small but noticeable effect on the price elasticities. Finally, controlling for housing characteristics and capital stock produces a lower price elasticity. - Highlights: • The price elasticity of residential electricity demand varies widely across studies. • We use three large datasets from the US to examine reasons for such wide variation. • Some assessed effects include aggregation, unobserved heterogeneity, and price trends. • Correcting for such issues can change the estimated price elasticity by 50–100%.

    2011-07-01

    This report focuses mainly on developments to improve the performance of coal-based power generation technologies, which should be a priority -- particularly if carbon capture and storage takes longer to become established than currently projected. A close look is taken of the major ongoing developments in process technology, plant equipment, instrumentation and control. Coal is an important source of energy for the world, particularly for power generation. To meet the growth in demand for energy over the past decade, the contribution from coal has exceeded that of any other energy source. Additionally, coal has contributed almost half of total growth in electricity over the past decade. As a result, CO2 emissions from coal-fired power generation have increased markedly and continue to rise. More than 70% of CO2 emissions that arise from power generation are attributed to coal. To play its role in a sustainable energy future, its environmental footprint must be reduced; using coal more efficiently is an important first step. Beyond efficiency improvement, carbon capture and storage (CCS) must be deployed to make deep cuts in CO2 emissions. The need for energy and the economics of producing and supplying it to the end-user are central considerations in power plant construction and operation. Economic and regulatory conditions must be made consistent with the ambition to achieve higher efficiencies and lower emissions. In essence, clean coal technologies must be more widely deployed.

  5. Quarterly coal report, January--March 1993

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-20

    The United States produced 242 million short tons of coal in the first quarter of 1993, a decrease of 6 percent (14 million short tons) from the amount produced during the first quarter of 1992. The decrease was due to a decline in production east of the Mississippi River. All major coal-producing States in this region had lower coal production levels led by West Virginia, which produced 5 million short tons less coal. The principal reasons for the overall drop in coal output compared to a year earlier were: A decrease in demand for US coal in foreign markets; a slower rate of producer/distributor stock build-up; and a drawn-down of electric utility coal stocks. Distribution of US coal in the first quarter of 1993 was 10 million short tons lower than in the first quarter of 1992, with 5 million short tons less distributed to both electric utilities and overseas markets. The average price of coal delivered to electric utilities during the first quarter of 1993 was $28.65 per short ton, the lowest value since the first quarter of 1980. Coal consumption in the first quarter of 1993 was 230 million short tons, 4 percent higher than in the first quarter of 1992, due primarily to a 5-percent increase in consumption at electric utility plants. Total consumer stocks, at 153 million short tons, and electric utility stocks, at 144 million short tons, were at their lowest quarterly level since the end of 1989. US. coal exports totaled 19 million short tons, 6 million short tons less than in the first quarter of 1992, and the lowest quarterly level since 1988. The decline was primarily due to a 1-million-short-ton drop in exports to each of the following destinations: Italy, France, Belgium and Luxembourg, and Canada.

    This project has generated comprehensive and realistic results of feasibilities for a coal-biomass to liquids (CBTL) plant in southern West Virginia; and evaluated the sensitivity of the analyses to various anticipated scenarios and parametric uncertainties. Specifically the project has addressed economic feasibility, technical feasibility, market feasibility, and financial feasibility. In the economic feasibility study, a multi-objective siting model was developed and was then used to identify and rank the suitable facility sites. Spatial models were also developed to assess the biomass and coal feedstock availabilities and economics. Environmental impact analysis was conducted mainly to assess life cycle analysis and greenhouse gas emission. Uncertainty and sensitivity analysis were also investigated in this study. Sensitivity analyses on required selling price (RSP) and greenhouse gas (GHG) emissions of CBTL fuels were conducted according to feedstock availability and price, biomass to coal mix ratio, conversion rate, internal rate of return (IRR), capital cost, operational and maintenance cost. The study of siting and capacity showed that feedstock mixed ratio limited the CBTL production. The price of coal had a more dominant effect on RSP than that of biomass. Different mix ratios in the feedstock and conversion rates led to RSP ranging from $104.3 - $157.9/bbl. LCA results indicated that GHG emissions ranged from 80.62 kg CO2 eq to 101.46 kg CO2 eq/1,000 MJ of liquid fuel at various biomass to coal mix ratios and conversion rates if carbon capture and storage (CCS) was applied. Most of water and fossil energy were consumed in conversion process. Compared to petroleum-derived-liquid fuels, the reduction in GHG emissions could be between -2.7% and 16.2% with CBTL substitution. As for the technical study, three approaches of coal and biomass to liquids, direct, indirect and hybrid, were considered in the analysis. The process models including

    Previous Studies have developed process designs, costs, and economics for the direct liquefaction of Illinois No. 6 and Wyoming Black Thunder coals at mine-mouth plants. This investigation concerns two case studies related to the liquefaction of Wyoming Black Thunder coal. The first study showed that reducing the coal liquefaction reactor design pressure from 3300 to 1000 psig could reduce the crude oil equivalent price by 2.1 $/bbl provided equivalent performing catalysts can be developed. The second one showed that incentives may exist for locating a facility that liquifies Wyoming coal on the Gulf Coast because of lower construction costs and higher labor productivity. These incentives are dependent upon the relative values of the cost of shipping the coal to the Gulf Coast and the increased product revenues that may be obtained by distributing the liquid products among several nearby refineries.

    Maintenance of a high oil value has an influence to energy crisis and national security in South Korea which does not have energy resources. The coals which have characterized by the abundant reserves and the inexpensive price can be said to be the alternative energy source. Hyper-coal process, which has been developed in Japan since 1999, is a new effective process to produce a clean coal by using the solvent de-ashing technology. When coal is extracted with organic solvent, only the organic portion of coal is dissolved in the solvents. That is possible to apply the low rank coal. This study was performed to produce ashless coal by using the solvent de-ashing technology. The experiment was conducted in the batch(or semi-batch) type reactor with two solvents such as NMP(N-methyl-2-pyrrolidinone) and 1-MN(1-methylnaphthalene) and various coals such as Kideko coal, Roto South coal and Sunhwa coal at 200-400{sup o}C. As a result of the test, extraction yield of coals was more than 60% on daf. Ash concentration which contains the extracted coal was 0.11-1.0wt%. The heat value was increased from 5,400 kcal/kg to 7,920 kcal/kg in the Roto South coal. 10 refs., 4 figs., 2 tabs.

    The report deals with the use of coal and coke in Sweden during 1994. Some information about technology, environmental questions and markets are also given. Data have been collected by questionnaires to major users and by telephone to minor users. Preliminary statistical data from Statistics Sweden have also been used.The use of steam coal for heating purposes has been unchanged during 1994 at a level of 1 Mtons. The production in the cogeneration plants has been constant, but has increased for electricity production. The minor plants have increased their use of forest fuels. The use of steam coal will probably go down in the next years both for heat and cogeneration plants. During the top year 1987 coal was used in 18 hot water and 11 cogeneration plants. 1994 these figures are 3 and 12. Taxes and environmental reasons explain this trend. The use of steam coal in industry has been constant at the level 0.7 Mtons. The import of metallurgical coal in 1993 was 1.6 Mtons, like 1992. Import of 0.3 Mtons of coke gives the total consumption of coke in industry as 1.5 Mtons. the average price of steam coal imported to Sweden was 317 SEK/ton, 3% higher than 1993. All Swedish plants meet their emission limit of dust, SO{sub 2} and NO{sub x} as given by county administrations or concession boards. The cogeneration plants all have some SO{sub 2} removal system. The biggest cogeneration plant (Vaesteraas) has recently invested in a SCR NO{sub x} cleaning system. Most other plants use low NO{sub x} burners or SNR injection systems based on ammonia or urea. 2 figs, 13 tabs.

    CO(2) emissions from the US power sector decreased by 8.76% in 2009 relative to 2008 contributing to a decrease over this period of 6.59% in overall US emissions of greenhouse gases. An econometric model, tuned to data reported for regional generation of US electricity, is used to diagnose factors responsible for the 2009 decrease. More than half of the reduction is attributed to a shift from generation of power using coal to gas driven by a recent decrease in gas prices in response to the increase in production from shale. An important result of the model is that, when the cost differential for generation using gas rather than coal falls below 2-3 cents/kWh, less efficient coal fired plants are displaced by more efficient natural gas combined cycle (NGCC) generation alternatives. Costs for generation using NGCC decreased by close to 4 cents/kWh in 2009 relative to 2008 ensuring that generation of electricity using gas was competitive with coal in 2009 in contrast to the situation in 2008 when gas prices were much higher. A modest price on carbon could contribute to additional switching from coal to gas with further savings in CO(2) emissions.

  14. Three essays on access pricing

    Science.gov (United States)

    Sydee, Ahmed Nasim

    access pricing with congestion and in which investments in infrastructure are lumpy. To fix ideas, the model is formulated in the context of airport infrastructure investments, which captures both the element of congestion and the lumpiness involved in infrastructure investments. The optimal investment program suggests how many units of capacity should be installed and at which times. Because time is continuous in the model, the discounted cost -- despite the lumpiness of capacity additions -- can be made to vary continuously by varying the time a capacity addition is made. The main results that emerge from the analysis can be described as follows: First, the global demand for air travel rises with time and experiences an upward jump whenever a capacity addition is made. Second, the access price is constant and stays at the basic level when the system is not congested. When the system is congested, a congestion surcharge is imposed on top of the basic level, and the congestion surcharge rises with the level of congestion until the next capacity addition is made at which time the access price takes a downward jump. Third, the individual demand for air travel is constant before congestion sets in and after the last capacity addition takes place. During a time interval in which congestion rises, the individual demand for travel is below the level that prevails when there is no congestion and declines as congestion worsens. The third essay contains a model of access pricing for natural gas transmission pipelines, both when pipeline operators are regulated and when they behave strategically. The high sunk costs involved in building a pipeline network constitute a serious barrier of entry, and competitive behaviour in the transmission pipeline sector cannot be expected. Most of the economic analyses of access pricing for natural gas transmission pipelines are carried out from the regulatory perspective, and the access price paid by shippers are cost-based.

    Because of economic growth and a strong increase in global energy demand the demand for fossil fuels and therefore also greenhouse gas emissions are increasing, although climate policy should lead to the opposite effect. The coal market is of special relevance as coal is available in many countries and often the first choice to meet energy demand. In this paper we assess possible interactions between climate policies and the global steam coal market. Possible market adjustments between demand regions through market effects are investigated with a numerical model of the global steam coal market: the “COALMOD-World” model. This equilibrium model computes future trade flows, infrastructure investments and prices until 2030. We investigate three specific designs of climate policy: a unilateral European climate policy, an Indonesian export-limiting policy and a fast-roll out of carbon capture and storage (CCS) in the broader context of climate policy and market constraints. We find that market adjustment effects in the coal market can have significant positive and negative impacts on the effectiveness of climate policies. - Highlights: ► Interactions between climate policy and the global coal market until 2030 modeled. ► Analysis with the numerical model: “COALMOD-World”. ► Unilateral European climate policy partly compensated by market adjustment effects. ► A fast roll-out of CCS can lead to positive market adjustment effects. ► An export restricting supply-side policy generates virtuous market adjustments.

  16. Coal: Less than lackluster

    Not many in the world coal industry will remember 1993 as a good year. The reasons for the poor state of affairs were first the weak economic climate, and second, the energy glut. For the first time after expanding steadily since the 70s, seaborne trade in hard coal fell by about 4% to 350M mt. Steam coal accounted for a good half of this volume. While demand continued to rise in the newly industrialized countries of the Pacific area, imports into Europe of both coking coal and steam coal fell sharply. The United States, CIS, and Canada had to accept substantial losses of export volume. Australia, as well as South Africa, Colombia, and Indonesia consolidated their market positions and Poland, too, recorded high volumes available for export. The positive news came from Australia, where in mid-December the New South Wales coal industry reported an increase in the net profit after tax from $A83M (about $55M) to $A98M (about $126M) in 1992/1993. This success was however ascribed less to an improvement in the fundamental mining indicators than to the fall in the Australian dollar and the lowering of corporate tax. The reduction in capital investment by 26% down to $A330M (after the previous year when it had also been cut by 25%) is seen by the chairman of the NSW Coal Assoc. as not auguring well for the industry's ability to meet the forecast growth in demand to the year 2000

    This paper investigates the efficient market hypothesis using total energy price and four kinds of various disaggregated energy prices - coal, oil, gas, and electricity - for OECD countries over the period 1978-2006. We employ a highly flexible panel data stationarity test of Carrion-i-Silvestre et al. [Carrion-i-Silvestre JL, Del Barrio-Castro T, Lopez-Bazo E. Breaking the panels: an application to GDP per capita. J Econometrics 2005;8:159-75], which incorporates multiple shifts in level and slope, thereby controlling for cross-sectional dependence through bootstrap methods. Overwhelming evidence in favor of the broken stationarity hypothesis is found, implying that energy prices are not characterized by an efficient market. Thus, it shows the presence of profitable arbitrage opportunities among energy prices. The estimated breaks are meaningful and coincide with the most critical events which affected the energy prices.

    In 2001 the Queensland coal industry consolidated on record expansion in the export market over the past two years and again, increased its sales to overseas customers. New sales records were set in both the export and domestic markets. Unprecedented international demand for Queensland metallurgical coals coupled with improved prices and a favourable A$-US$ exchange rate created strong market conditions for the Queensland coal export industry, boosting confidence for further expansion and new developments. Australian coal exports in 2001 amounted to 194 Mt and are forecast to reach 275 million tonnes per annum (Mtpa) in 2020. The Queensland coal industry is poised to capture a significant share of this market growth. Queensland's large inventory of identified coal, currently estimated at more than 37 billion tonnes (raw coal m situ), is adequate to sustain the industry for many years and allow new opencut and underground mines to develop according to future market demand. Recent coal exploration successes are expected to add significant tonnage to the inventory (Coxhead, Smith and Coffey, 2002). Most of the coal exported from Queensland is mined in the Bowen Basin of central Queensland and additional tonnage of Walloon coal is exported by mines in the Moreton Basin and Surat Basin in south-east Queensland. The Walloon Coal Measures and its equivalents contain large resources of undeveloped opencut, high volatile, clean-burning thermal coal. The environmental advantages in the utilisation of these coals are now recognised and strong growth in production is expected in the near future for supply to both the domestic and export markets. Establishment of new rail transport and civil infrastructure will however, be required to support the development of large scale mining operations in this region

    In the scope of four related essays this thesis analyses the Chinese domestic coal sector and coal trade policies and their respective impact on international steam coal trade economics. In particular, the thesis investigates the role of domestic transport infrastructure investment policies as well as Chinese coal export and import controls and the potential exertion of market power through such trade instruments. For this purpose, several spatial equilibrium models have been developed that enable simulation runs to compare different policy scenarios. These models also permit ex-post analyses to empirically test hypotheses of non-competitive market conduct of individual players under the assumption of Cournot behaviour. These model-based analyses yield, among others, the following findings: If coal is converted into electricity early in the Chinese energy supply chain, worldwide marginal costs of supply are substantially lower than if coal is transported via railway. This can reduce China's dependence on international imports significantly. Allocation of welfare changes, particularly in favour of Chinese consumers while rents of international producers decrease. If not only seaborne trade but also interactions and feedbacks between domestic coal markets and international trade markets are accounted for, trade volumes and prices of a China - Indonesia duopoly fit the real market outcome best in 2008. Real Chinese export quotas have been consistent with simulated exports under a Cournot-Nash strategy. Uncertainties with regard to future Chinese coal demand and coal sector policies generate significant costs for international investors and lead to a spatial and temporal reallocation of mining and infrastructure investments. The potential exertion of Chinese demand side market power would further reduce the overall investment activity of exporters.

    Full Text Available Land provision is one of the biggest challenges for development in urban area. Most of the available urban land will be the object of speculation to be resold at a higher price when the time is right. In Jabodetabek, where the pace of urban development is faster than other parts of Indonesia, the prices of land show an abnormal increase; they seem to rise too fast. This paper discusses the increasing land prices in Jabodetabek area and argues that the increasing land price has encourages the private developer to bank the land in the area. Based on land price survey in Jabodetabek, urban activity is moving to south Jakarta. The highest land prices were found at East Kuningan, Setiabudi, and South Jakarta. By constrast, the lowest prices were observed in Sumur Batu and Cimuning (Bantar Gebang, Bekasi.It can be concluded that the land price increase also triggered land banking practice in Jabodetabek reaching in total approximately 60% of total area of Jakarta.

    The low-temperature carbonization process of coal is a technology to produce high grade reformed coal corresponding to bituminous coal and coal oil corresponding to heavy oil from subbituminous coal and supply them at prices close to the present market ones. From viewpoints of diversified sources and multiple export harbors, an initial-stage survey was conducted of the whole flow from new development of undeveloped mining areas in the northwest of Sumatra, Indonesia to bringing by ships to Japan of products reformed by LFC process of the US SGI`s low-temperature carbonization technology. Clean coal prepared after mining is produceable at a little higher than $12. At processing ability of 10,000 tons/day of raw coal, production is expected of approximately 5,700 tons/day of solid products of more than 6,500 kcal/kg and approximately 1,000 tons/day of low sulfur C heavy oil class oil. The finished cost of solid products is about $25/ton, which becomes about $40/ton at the harbor price in Japan. In conclusion, the project to enhance the quality of subbituminous coal by the low-temperature carbonization is promising as a total system. 10 refs., 54 figs., 30 tabs.

  5. A 1,000 GtC Coal Question for Future Energy Scenarios: How Much Coal Will Renewables Need to Displace?

    Ritchie, W. J.; Dowlatabadi, H.

    2016-12-01

    Twenty years ago, global coal assessments indicated reserve-to-production (R-P) ratios of more than 300 years. Consequently, most studies of energy futures established coal as a virtually unlimited backstop to meet the world's projected energy needs. Coal was modeled to offset oil and gas production declines and provide a source of energy which renewables and lower carbon supply strategies needed to outcompete. Over the past two decades, increasingly consistent methodologies have been applied globally to assess recoverable coal. Coal production has also witnessed significant mechanization to meet higher demand. Each of these has led to a significant reduction in estimates of economically recoverable coal reserves despite a doubling of market prices over this period. The current reserve to production ratio for coal is now around 100 years. It is time to reconsider coal as the inexhaustible energy backstop The energy models which develop long-term estimates of renewable energy needs and projections of greenhouse gas (GHG) emissions still adopt the characteristics of vintage coal assessments. By convention, baseline GHG emissions used by the IPCC and others, project combustion of most known coal reserves before the year 2100. When vintage assessments are used, this involves extraction of all currently known coal reserves plus twice again from resources invalidated as recoverable for geologic, environmental, social, legal, technical or economic reasons. We provide evidence for rejecting these projections of unbounded growth in coal consumption. Legacy pathways of implausibly high coal use upwardly bias long-term scenarios for total cumulative GHG emissions and subsequent research on climate change. This bias has precluded consideration of much more ambitious climate mitigation targets without significant socio-economic dislocation and unnecessarily diminishes possible future contributions from renewables.

    2009-01-01

    Studies that estimate deficit probabilities in hydrothermal systems have generally ignored the response of demand to changing prices, in the belief that such response is largely irrelevant. We show that ignoring the response of demand to prices can lead to substantial over or under estimation of the probability of an energy deficit. To make our point we present an estimation of deficit probabilities in Chile's Central Interconnected System between 2006 and 2010. This period is characterized by tight supply, fast consumption growth and rising electricity prices. When the response of demand to rising prices is acknowledged, forecasted deficit probabilities and marginal costs are shown to be substantially lower

    This work analyses the carbon dioxide (CO2) capture system operation within the Electric Reliability Council of Texas (ERCOT) and Great Britain (GB) electric grids using a previously developed first-order hourly electricity dispatch and pricing model. The grids are compared in their 2006 configuration with the addition of coal-based CO2 capture retrofits and emissions penalties from 0 to 100 US dollars per metric ton of CO2 (USD/tCO2). CO2 capture flexibility is investigated by comparing inflexible CO2 capture systems to flexible ones that can choose between full- and zero-load CO2 capture depending on which operating mode has lower costs or higher profits. Comparing these two grids is interesting because they have similar installed capacity and peak demand, and both are isolated electricity systems with competitive wholesale electricity markets. However, differences in capacity mix, demand patterns, and fuel markets produce diverging behaviours of CO2 capture at coal-fired power plants. Coal-fired facilities are primarily base load in ERCOT for a large range of CO2 prices but are comparably later in the dispatch order in GB and consequently often supply intermediate load. As a result, the ability to capture CO2 is more important for ensuring dispatch of coal-fired facilities in GB than in ERCOT when CO2 prices are high. In GB, higher overall coal prices mean that CO2 prices must be slightly higher than in ERCOT before the emissions savings of CO2 capture offset capture energy costs. However, once CO2 capture is economical, operating CO2 capture on half the coal fleet in each grid achieves greater emissions reductions in GB because the total coal-based capacity is 6 GW greater than in ERCOT. The market characteristics studied suggest greater opportunity for flexible CO2 capture to improve operating profits in ERCOT, but profit improvements can be offset by a flexibility cost penalty.

    Fluctuating energy prices have a significant impact on the economies of industrialized nations. A recent study has shown a strong non-linear relationship between changes in oil prices and growth in gross domestic product (GDP). In order to forecast the behaviour of energy prices, a complete model must take into account domestic and international supply and demand conditions, market regulations, technological advances and geopolitics. In 1999, Pindyck suggested that for long-term forecasting, a simple model should be adopted where prices grow in real terms and at a fixed rate. This paper tests the statistical significance of Pindyck's suggested class of econometric equations that model the behaviour of long-run real energy prices. The models assume mean-reverting prices with continuous and random changes in their level and trend. They are estimated using Kalman filtering. The authors used simulation-based procedures to address the issue of non-standard test statistics and nuisance parameters. Results were reported for a standard Monte Carlo test and a maximized Monte Carlo test. Results shown statistically significant instabilities for coal and natural gas prices, but not for crude oil prices. Various models were differentiated using out-of-sample forecasting exercises. 25 refs., 3 tabs

  11. Assessment and Decomposition of Total Factor Energy Efficiency: An Evidence Based on Energy Shadow Price in China

    Directory of Open Access Journals (Sweden)

    Peihao Lai

    2016-04-01

    Full Text Available By adopting an energy-input based directional distance function, we calculated the shadow price of four types of energy (i.e., coal, oil, gas and electricity among 30 areas in China from 1998 to 2012. Moreover, a macro-energy efficiency index in China was estimated and divided into intra-provincial technical efficiency, allocation efficiency of energy input structure and inter-provincial energy allocation efficiency. It shows that total energy efficiency has decreased in recent years, where intra-provincial energy technical efficiency drops markedly and extensive mode of energy consumption rises. However, energy structure and allocation improves slowly. Meanwhile, lacking an integrated energy market leads to the loss of energy efficiency. Further improvement of market allocation and structure adjustment play a pivotal role in the increase of energy efficiency.

  12. The oil price and non-OPEC supplies

    International Nuclear Information System (INIS)

    Seymour, A.

    1990-01-01

    The purpose of this study is to examine in detail a major supply development - that of non-OPEC oil in the 1970s and 1980s - in order to determine whether a part, if any, of the increase in non-OPEC production after the price shocks was unambiguously due to decisions and developments that preceded the price shocks. This 'historical' approach which examines facts in detail and in their exact chronology enables us to disaggregate the increase in non-OPEC production into two parts; one that is totally independent of the price shocks and one that could not be said in all certainty to have been influenced by the price rise. This study thus provides a maximalist answer to the question: 'How much of the increase is non-OPEC supplies was due to the price shocks?' Our main finding however is that the maximum amount that can be attributed to the price rise is but a fraction of the total supply increase. As a foundation on which to generalize on the effect of the oil price shocks on non-OPEC supplies as a whole, case studies on eighteen non-OPEC producers are presented. These are: the UK, Norway, Egypt, Mexico, Angola, Cameron, the Congo, Brazil, Colombia, Peru, Australia, India, the Federation of Malaysia, Oman, the USA, Canada, the USSR and China. Together, these countries have accounted for over 90% of total cumulative non-OPEC supply between 1974 and 1987, inclusive. (author)

    1997-12-31

    Over the next 20 years, the combination of slow growth in the demand for electricity, even slower growth in the need for new capacity, especially baseload capacity, and the competitiveness of new gas-fired technologies limits the market for new coal technologies in the US. In the later years of the 1997 Annual Energy Outlook projections, post-2005, when a significant amount of new capacity is needed to replace retiring plants and meet growing demand, some new coal-fired plants are expected to be built, but new gas-fired plants are expected to remain the most economical choice for most needs. The largest market for clean coal technologies in the United States may be in retrofitting or repowering existing plants to meet stricter environmental standards, especially over the next 10 years. Key uncertainties include the rate of growth in the demand for electricity and the level of competing fuel prices, particularly natural gas. Higher than expected growth in the demand for electricity and/or relatively higher natural gas prices would increase the market for new coal technologies.

  14. Can switching fuels save water? A life cycle quantification of freshwater consumption for Texas coal- and natural gas-fired electricity

    International Nuclear Information System (INIS)

    Grubert, Emily A; Beach, Fred C; Webber, Michael E

    2012-01-01

    Thermal electricity generation is a major consumer of freshwater for cooling, fuel extraction and air emissions controls, but the life cycle water impacts of different fossil fuel cycles are not well understood. Much of the existing literature relies on decades-old estimates for water intensity, particularly regarding water consumed for fuel extraction. This work uses contemporary data from specific resource basins and power plants in Texas to evaluate water intensity at three major stages of coal and natural gas fuel cycles: fuel extraction, power plant cooling and power plant emissions controls. In particular, the water intensity of fuel extraction is quantified for Texas lignite, conventional natural gas and 11 unconventional natural gas basins in Texas, including major second-order impacts associated with multi-stage hydraulic fracturing. Despite the rise of this water-intensive natural gas extraction method, natural gas extraction appears to consume less freshwater than coal per unit of energy extracted in Texas because of the high water intensity of Texas lignite extraction. This work uses new resource basin and power plant level water intensity data to estimate the potential effects of coal to natural gas fuel switching in Texas’ power sector, a shift under consideration due to potential environmental benefits and very low natural gas prices. Replacing Texas’ coal-fired power plants with natural gas combined cycle plants (NGCCs) would reduce annual freshwater consumption in the state by an estimated 53 billion gallons per year, or 60% of Texas coal power’s water footprint, largely due to the higher efficiency of NGCCs.

    An analysis of the global petroleum resources and demand shows that the amount of mineral oil products is sufficient to meet the requirements of the next decades. The geographical resources, however, could lead to problems of distribution and foreign exchange. The production of hydrocarbons with coal as basis using high temperature nuclear process heat has advantages compared to the conventional techniques. Next to the conservation of reserve fossil primary energy carriers there are advantages as regards prices, which at high coal costs are especially pronounced. (orig.) [de

    1993-10-01

    The long-term wholesale electricity market is becoming increasingly competitive. Bidding for power contracts has become a dominant form of competition in this sector. The prices which emerge from this process have not been documented and compared in a systematic framework. This paper introduces a method to make such comparisons and illustrates it on a small sample of projects. This results show a wide range of prices for what is essentially the same technology, gas-fired combined cycle generation. The price range seems greater than what could be explained by transmission cost differences between high and low cost regions. For the smaller sample of coal-fired projects, price variation is substantially less. Further data collection and analysis should be able to help isolate more clearly what market or cost factors are responsible for the observed variation.

    Amano, R.A.; Norden, S. van.

    1993-12-01

    It is examined whether a link exists between oil price shocks and the U.S. real effective exchange rate. Data used for the study are described and their time series properties and the long-run explanatory power of oil prices for the real exchange rate are examined. Apparent causal relationships between exchange rates and oil prices are examined. An unrestricted error correction model is reduced until an error correction model with reasonable properties is derived. Results show that the two variables appear to be cointegrated and that causality runs from oil prices to the exchange rate and not vice-versa. The single equation error correction model linking these two variables is stable and captures much of the in- and out-of-sample movement in the exchange rate in dynamic simulation. Tests are presented to show that the error correction model has significant post-sample predictive ability for both the size and sign of changes in the real effective exchange rate. The results suggest that oil prices may have been the dominant source of persistant real exchange rate shocks over the post-Bretton Woods period and that energy prices may have important implications for future work on exchange rate behaviour. 61 refs., 3 figs., 7 tabs

    The possibility of using electricity dispatching strategies to achieve a 50% nitrogen oxide (NOx) emission reduction from electricity generating units was examined using the grid of the Electricity Reliability Council of Texas as a case study. Simulations of a hypothetical policy demonstrate that imposing higher NOx prices induces a switch from some coal-fired generation to natural gas generation, lowering NOx emissions. The simulation is for a day with relatively high electricity demand and accounts for transmission constraints. In addition to the lowering of the NOx emissions, there are co-benefits of the redispatching of generation from coal to natural gas, including reductions in the emissions of sulfur oxides (24%-71%), Hg (16%-82%) and CO2 (8.8%-22%). Water consumption was also decreased, by 4.4%-8.7%. Substantial reductions of NOx emissions can be achieved for an increased generation cost of 4-13%, which is due to the higher fuel price of gas relative to coal (assuming a price of 3.87 per MMBTU (MMBTU: million British thermal units) for natural gas, and 1.89 per MMBTU for coal). However, once the system has reduced NOx emissions by approximately 50%, there is little incremental reduction in emissions due to further increases in NOx prices.

  20. Energy strategy would slow coal's growth, says DOE

    International Nuclear Information System (INIS)

    1991-01-01

    The National Energy Strategy (NES) recently announced by the Bush Administration would slow the growth in use of coal by hundreds of millions of tons of coal by hundreds of millions of tons after 2000, according to the Department of Energy's (DOE) own figures. If today's policies are continued, coal consumption will nearly triple by 2030. Current annual consumption of more than 900 million tons (19 quadrillion Btus) would rise to 1,550 million tons in 2010 and to nearly 2,600 million tons by 2030. Coal's share of electricity generation, now about 55%, would grow to 75% by 2030 under the current policy base assumptions of the DOE. The NES, however, projects that surge of nuclear power plant construction will stem the growth of coal use. The strategy would still increase coal use, from 19 quadrillion Btus today to about 28 quads in 2010, but to only 32 quads by 2030. By 2030, coal would account for less than 50% of electricity generation under the NES. Total clean coal technologies capacity is substantially lower under the NES scenario case than under the clean coal actions alone. The strategy also contains good news for the coal industry in the short run. It holds out two main goals for coal policy: maintaining coal's competitiveness while meeting environmental, health and safety requirements; and creating a favorable export climate for US coal and coal technology

    The importance of coal for energy and economic security in Russia is being reconsidered. Following revival of the world coal market, Russian coal exports reached a peak of 42 mt in the year 2000. However, coal demand by the national market is low as the economy is oriented towards natural gas. The poor condition of mine transport and mining machinery hampers coal exports. 70% of the country's coal output is from private companies which currently have insufficient funds for investment needed. Rises in railway rates for coal have affected the competitiveness of coal both at home and abroad. However, these problems are not unsurmountable and the market for Russian coal is predicted to grow up to 2005, mainly with coal from the Kuznetsk Basin. From 2005-2010 exports will depend on commissioning of new export-oriented capacity and completion of a railway line and coal terminal.

    At the last moment Kosice managed to overcome the threat of a more than 30-percent heating price increase. The biggest local heat producer, Teplaren Kosice, is running out of coal supplies. The only alternative would be gas, which is far more expensive. The reason for this situation was a dispute of the heating plant with one of its suppliers, Kimex. Some days ago, the dispute was settled and the heating plant is now expecting the first wagon loads of coal to arrive. These are eagerly awaited, as its supplies will not last for more than a month. It all started with a public tender for a coal supplier. Teplaren Kosice (TEKO) announced the tender for the delivery of 120,000 tons of coal in June. Kimex, one of the traditional and biggest suppliers, was disqualified in the course of the tender. The winners of the tender were Slovenergo, Bratislava and S-Plus Trade, Vranov nad Toplou. TEKO signed contracts with them but a district court in Kosice prohibited the company from purchasing coal from these contractors. Kimex filed a complaint claiming that it was disqualified unlawfully. Based on this the court issued a preliminary ruling prohibiting the purchase of coal from the winners of the tender. The heating plant had to wait for the final verdict. The problem was then solved by the company's new Board of Directors, who were appointed in mid October who managed to sign new contracts with the two winners and Kimex. The new contracts cover the purchase of 150-thousand tons of coal, which is 30,000 more than in the original tender specification. Each company will supply one third. (authors)

    The Chinese government recently released the 13th FYP (five-year plan) power development plan and proposed a capacity installation target of 1100 GW for coal power. Considering the weak demand growth of coal power since 2014, continuous decline in the annual utilisation hour and the coming market competition, such a planning target is unwelcome and could further the economic deterioration of coal power. In this paper, we employ LCOE (levelised cost of electricity) and project evaluation models to conduct a nationwide survey on the economics of coal power. The economic analysis has clearly indicated that the recent boom of coal power investment in China, which is absurd in many perspectives, is largely the aftermath of uncompleted market reform in the power sector. However, the fundamentals of electricity demand and supply are changing at a speed beyond the imagination of power generators and have foreboded a gloomy prospect for coal power. Our study shows that by 2020, with several exceptions, in most provinces the internal rate of return for coal power will drop below the social average return rate or will even be negative. In this regard, the 13th FYP capacity planning target for coal power is economically untenable and requires radical revision. - Highlights: • Conduct a first-of-its-kind nationwide economic analysis for coal power in China. • Distorted price by improper regulation is the root of investment bubble since 2014. • Cost uplift and market competition foretell a gloomy prospect of coal power. • The 1100 GW capacity planning target for coal power should be abandoned.

    The People`s Republic of China (hereafter referred to as China) is the largest producer and consumer of coal in the world. The dominance of coal in China`s energy balance has come at a high price to the environment. With the recent attention given to global warming issues, China`s energy consumption and production practices have become the subject of much concern. Of particular concern is China`s ability to reduce CO{sub 2} emissions by constraining coal use and the impact such policies will likely have on the Chinese economy. The study is divided into two reports. Volume 1 focuses on the full coal fuel cycle, emissions, and environmental effects. This report (Volume 2) analyzes various CO{sub 2} mitigation strategies and determines their effect on economic growth. Contrary to what some analysts have claimed, the current work suggests that it would not be costly for the Chinese to reduce CO{sub 2} emissions. In fact, some strategies were accompanied by increases in China`s energy and economic efficiency, which actually stimulated economic growth.

    In the wide range from brown coal to anthracite, an investigation was made of effects of heat treatment on physical/chemical properties and of coal rank dependence. For the experiment, 12 kinds of coal samples were used, and for heat treatment, the fluidized bed heated by the electric furnace and the infrared-ray gold image furnace were used. To examine characteristics of the heat-treated coal char, conducted were oxygen gasification, TPD measurement, XRD measurement, alkali metal measurement, and pore distribution measurement. The following were obtained from the experiment. The gasification reaction rate of the char heat-treated in the temperature range between 900{degree}C to 1700{degree}C decreases with a rise of the temperature of heat treatment, and the degree of decrease in the rate depends on coal rank. The order of gasification rate between coal ranks depends on the temperature of heat treatment, and the lower the heat treatment temperature is, the more largely the gasification rate is influenced by catalysis of mineral matters included in the coal. As causes of the decrease in gasification rate associated with the rise in temperature of heat treatment, indicated were release of alkali metal having catalysis and decrease of active sites by carbonaceous crystallinity. 6 figs.

  8. Hedging electricity price volatility using nuclear power

    Highlights: • Nuclear power is an important asset to reduce the volatility of electricity prices. • Unpredictability of fossil fuels and carbon prices makes power prices very volatile. • The dynamics of fossil fuels and carbon prices is described by Brownian motions. • LCOE values, volatilities and correlations are obtained via Monte Carlo simulations. • Optimal portfolios of generating technologies are get using a mean–variance approach. - Abstract: The analysis presented in this paper aims to put in some evidence the role of nuclear power as hedging asset against the volatility of electricity prices. The unpredictability of natural gas and coal market prices as well as the uncertainty in environmental policies may affect power generating costs, thus enhancing volatility in electricity market prices. The nuclear option, allowing to generate electricity without carbon emissions, offers the possibility to reduce the volatility of electricity prices through optimal diversification of power generating technologies. This paper provides a methodological scheme to plan well diversified “portfolios” of generating capacity that minimize the electricity price risk induced by random movements of fossil fuels market prices and by unpredictable fluctuations of carbon credits prices. The analysis is developed within a stochastic environment in which the dynamics of fuel prices as well as the dynamics of carbon credits prices is assumed to evolve in time according to well defined Brownian processes. Starting from market data and using Monte Carlo techniques to simulate generating cost values, the hedging argument is developed by selecting optimal portfolio of power generating technologies using a mean–variance approach

    European Union public healthcare expenditure on treating smoking and attributable diseases is estimated at over €25bn annually. The reduction of tobacco consumption has thus become one of the major social policies of the EU. This study investigates the effects of price hikes on cigarette consumption, tobacco tax revenues and smoking-caused deaths in 28 EU countries. Employing panel data for the years 2005 to 2014 from Euromonitor International, the World Bank and the World Health Organization, we used income as a threshold variable and applied threshold regression modelling to estimate the elasticity of cigarette prices and to simulate the effect of price fluctuations. The results showed that there was an income threshold effect on cigarette prices in the 28 EU countries that had a gross national income (GNI) per capita lower than US$5418, with a maximum cigarette price elasticity of -1.227. The results of the simulated analysis showed that a rise of 10% in cigarette price would significantly reduce cigarette consumption as well the total death toll caused by smoking in all the observed countries, but would be most effective in Bulgaria and Romania, followed by Latvia and Poland. Additionally, an increase in the number of MPOWER tobacco control policies at the highest level of achievment would help reduce cigarette consumption. It is recommended that all EU countries levy higher tobacco taxes to increase cigarette prices, and thus in effect reduce cigarette consumption. The subsequent increase in tobacco tax revenues would be instrumental in covering expenditures related to tobacco prevention and control programs.

    There has been recent increased interest in the development of and investment in the Canadian coal industry because of rising natural gas prices and increased demand for coking coal. Several new Canadian producers have commenced mining and shipping coal. Premium hard coking coal prices have risen, from $40 US in 2000 to above $100 US per tonne in 2006. The resource sector is challenged by higher energy costs, increasing transportation costs, problems with equipment and parts procurement, and the recruitment and retention of skilled mining employees. Mineral exploration and development has risen seven-fold in British Columbia since 2001, where the province now offers a competitive business and taxation environment as an incentive to resource development. Coal represents 40% of British Columbia's mining revenue.

    The steam gasification of pit coal requires temperatures which cannot yet be reached with the present state of HTGR technology for material technical reasons. The use of nuclear heat thus remains limited to some fields of application outside the gasifier, which are specified. The production costs of synthetic natural gas from autothermal gasification on the one hand, and from combined auto-allothermal gasification on the other hand are calculated considering the heat price of pit coal and of the selling price of electrical energy and are compared.

    Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

  14. Comparison of costs of electricity generation based on nuclear energy and pit coal

    International Nuclear Information System (INIS)

    1981-01-01

    Despite of a meanwhile considerable increase in costs of installation, especially of nuclear power stations, the differences in costs have increased in favour of nuclear electricity generation. The cost advantages are estimated 4 German Pfennig per kilowatt-hour in the base-load field for plants coming into operation at the end of this decade compared with the most profitable variant of pit coal utilization on which this investigation is based; compared to the use of German hard coal, assuming a relatively optimistic development of prices for domestic hard coal in the future, the cost advantage is estimated 8 German Pfennig per kilowatt-hour. The main reason is that in the past years the price for German hard coal as well as for imported coal considerably rose and for the future further increases have to be expected whereas the largest share of the costs of nuclear electricity generation doesn't increase, after the plant is completed. Considering the importance of the fuel costs within the total costs of electricity generation in coal power stations this must have its effects on the total result. These results also prove to be valid for a variation of important cost parameters. Only if the unlikely assumption that considerable variations of influences on costs - each unfavourable effecting nuclear electricity generation - would come together would prove to be true the economic efficiency of nuclear energy would be reduced or questioned.

    2016-01-01

    After the liberalisation of the gas industry, trading hubs have emerged in Europe. Although these hubs appear to be liquid market places fostering gas-to-gas competition, the efficiency of the gas market remains a topic of interest as a fair share of gas is still traded through long-term contracts with prices linked to the oil price while the number of gas suppliers to the European market is limited. In order to assess the efficiency of the gas market, we analyse the day-ahead spot price at the Dutch gas hub over the period 2011–2014. We find that the oil price had a small positive impact on the gas price. Changes in the concentration on the supply side did not affect the movement in gas prices. The availability of gas in storages and the outside temperature negatively influenced the gas price. We also find that the gas price was related to the production of wind electricity. Overall, we conclude that the day-ahead gas prices are predominantly determined by gas-market fundamentals. Policies to further integrate gas markets within Europe may extend this gas-to-gas competition to a larger region. - Highlights: •We analyse the development of the day-ahead spot price at TTF over 2011–2014. •The oil price had a small impact on the gas price, while the coal price had no effect. •Changes in the concentration on the supply side did not affect the gas prices. •The gas prices are predominantly determined by weather and storage availability. •Policies to integrate gas markets foster gas-to-gas competition.

  16. Energy prices, volatility, and the stock market. Evidence from the Eurozone

    2009-01-01

    This paper constitutes a first analysis on stock returns of energy corporations from the Eurozone. It focuses on the relationship between energy market developments and the pricing of European energy stocks. According to our results, oil price hikes negatively impact on stock returns of European utilities. However, they lead to an appreciation of oil and gas stocks. Interestingly, forecastable oil market volatility negatively affects European oil and gas stocks, implying profit opportunities for strategic investors. In contrast, the gas market does not play a role for the pricing of Eurozone energy stocks. Coal price developments affect the stock returns of European utilities. However, this effect is small compared to oil price impacts, although oil is barely used for electricity generation in Europe. This suggests that for the European stock market, the oil price is the main indicator for energy price developments as a whole. (author)

    Davies, G.

    2004-01-01

    This PowerPoint presentation examined the efficacy of a governmental decision in 2003 to close all Ontario coal stations by 2007. Coal currently represents one quarter of Ontario's energy and capacity. Projected supply and demand gaps for Ontario were presented for up to 2020. Ontario's supply options were outlined. It was noted that between $30 and $40 billion in investment in the electricity sector will be needed over the next 10 to 15 years. It was observed that closing coal plants may reduce pollution by 6 per cent at a cost of $2 billion. More than half the smog affecting Ontario comes from the United States, while much of the remaining half is caused by transportation emissions. Details of energy strategies related to coal in the United States were discussed. New coal power plant technologies include supercritical combustion; advanced air pollution control; circulating fluidized bed combustion and integrated coal gasification combined cycles. Coal power plant performance criteria were presented. Various research programs in the United States were reviewed, and roadmap performance targets were presented. It was concluded that high prices and uncertainty for natural gas fired options may reinforce views on the need to rethink coal closures. A strategy was recommended in which Ontario pursued economic options for reducing emissions across all sectors. New investments in latest and best technology for emissions reduction in Ontario's coal-fired stations were recommended, as well as a North American agreement on clean air, and increased Canadian participation in U.S. technology development efforts for clean coal and zero emissions plants by 2025. tabs., figs

  20. Oil prices: The role of refinery utilization, futures markets and non-linearities

    2008-01-01

    We test the hypothesis that real oil prices are determined in part by refinery capacity, non-linearities in supply conditions, and/or expectations and that observed changes in these variables can account for the rise in prices between 2004 and 2006. Results indicate that the refining sector plays an important role in the recent price increase, but not in the way described by many analysts. The relationship is negative such that higher refinery utilization rates reduce crude oil prices. This effect is associated with shifts in the production of heavy and light grades of crude oil and price spreads between them. Non-linear relationships between OPEC capacity and oil prices as well as conditions on the futures markets also account for changes in real oil prices. Together, these factors allow the model to generate a one-step ahead out-of-sample forecast that performs as well as forecasts implied by far-month contracts on the New York Mercantile Exchange and is able to account for much of the $27 rise in crude oil prices between 2004 and 2006.

  1. Is there an asymmetry in the response of diesel and petrol prices to crude oil price changes? Evidence from New Zealand

    2010-01-01

    This paper examines how pre-tax petrol and diesel prices in New Zealand respond to changes in crude oil prices using an asymmetric error correction model. Our results show that oil companies adjust diesel prices upwards faster than they adjust them downwards, and the difference is statistically significant. However we find no statistical evidence for an asymmetry in the adjustment of petrol prices even though the magnitude of estimated coefficients suggests a faster response to rising prices. As diesel pricing is not as competitive as petrol pricing, calls for further government actions and monitoring of the oil market may be justified. Our findings also have important implications for the conduct of monetary policy as the pass-through of crude oil price changes can affect cost-push inflation. (author)

    2013-11-01

    Because cigarette price minimization strategies can provide substantial price reductions for individuals continuing their usual smoking behaviors following federal and state cigarette excise tax increases, we examined independent price reductions compensating for overlapping strategies. The possible availability of larger independent price reduction opportunities in states with higher cigarette excise taxes is explored. Regression analysis used the 2006-2007 Tobacco Use Supplement of the Current Population Survey (N = 26,826) to explore national and state-level independent price reductions that smokers obtained from purchasing cigarettes (a) by the carton, (b) in a state with a lower average after-tax cigarette price than in the state of residence, and (c) in "some other way," including online or in another country. Price reductions from these strategies are estimated jointly to compensate for known overlapping strategies. Each strategy reduced the price of cigarettes by 64-94 cents per pack. These price reductions are 9%-22% lower than conventionally estimated results not compensating for overlapping strategies. Price reductions vary substantially by state. Following cigarette excise tax increases, the price reduction available from purchasing cigarettes by cartons increased. Additionally, the price reduction from purchasing cigarettes in a state with a lower average after-tax cigarette price is positively associated with state cigarette excise tax rates and border state cigarette excise tax rate differentials. Findings from this large, nationally representative study of cigarette smokers suggest that price reductions are larger in states with higher cigarette excise taxes, and increase as cigarette excise taxes rise.

    This publication denounces some myths and, as answers, states some realities regarding France, the World and coal, i.e.: Through its reduction of greenhouse gas emissions, France is an example in the struggle against climate change at the international level (whereas France still supports the development of very emitting projects like coal-fired plants in France and abroad); The construction of new coal plants would comply with the objective defined by the international community to limit world mean temperature rise below 2 deg. C (whereas such a construction does not actually comply with this objective); To be against coal is to go against poverty eradication (whereas there are better alternatives than coal to promote access to energy and eradicate poverty); It's better to replace old existing coal plants by new and more efficient coal plants (whereas great economic powers are now closing coal plants to replace them with renewable energies); As China is not yet ready to struggle against climate change, there is no use to withdraw support to coal projects (whereas China is now implementing measures to struggle against climate change)

  4. Modelling the transition from cost-based to bid-based pricing in a deregulated electricity-market

    Druce, Donald J.

    2007-01-01

    Alberta is a province in western Canada with a deregulated electricity-market. Market clearing prices for most hours reflect the cost of either coal-fired or gas-fired thermal generation. Whenever there is a chronic shortage of generation or even a temporary one due to an outage, prices can be bid much higher than fuel costs would suggest. The province of British Columbia borders Alberta to the west and its electric utility, BC Hydro, has a history of trade with the utilities in Alberta. BC Hydro has predominantly hydroelectric resources and large storage reservoirs. Prior to Alberta's deregulation in 1996, BC Hydro was able to enter into mutually beneficial load-factoring contracts with the Alberta utilities. Now, as long as the transmission is available, BC Hydro can buy low priced off-peak coal-fired energy and sell into the high priced periods without having to share the benefits. BC Hydro uses a combination of econometric and Monte Carlo modelling to simulate hourly price-duration curves for Alberta that capture both cost-based and bid-based characteristics. This approach provides a good fit with the stochastic dynamic programming model that BC Hydro has developed for its mid-term hydro scheduling

He outlines their availability, locations, and different main geographical areas. Then, he discusses the relationships between costs and prices in which intervene external costs, taxes, feed-in tariffs, national regulations, incentives for consumers. He discusses the issue of regulation of some energy activities, i.e. how State may or may not intervene on the markets, how competition may influence the market, how activities can thus be divided (production, transport, distribution) with implications and consequences for prices. He finally outlines concerns about the future financing of investments required to face tomorrow's needs

    The Russian energy industry may be the country's most promising exporter, but it is struggling to free itself from the heavy regulation and economic distortions inherited from the Soviet era. This analysis examines Russian price and tax policies as well as production costs in 1993, and their effect on supply and demand in the oil, coal, gas and electricity sectors. The study underscores the broad consensus among both Western and Russian experts that primary energy prices should be lifted to world levels. It offers a framework for addressing the great question about how fast this should be done in a country undergoing a tremendous social and political transformation

During its transportation from coal sites to power plant locations is required the eligible shipping line services that are able to provide the best freight rate. Therefore, this study aims to obtain the standardized formulations for determining the ocean freight especially for coal distribution based on the theoretical concept. The freight calculation model considers three alternative transport modes commonly used in coal distribution: tug-barge, vessel and self-propelled barge. The result shows there are two cost components very dominant in determining the value of freight with the proportion reaching 90% or even more, namely: time charter hire and fuel cost. Moreover, there are three main factors that have significant impacts on the freight calculation, which are waiting time at ports, time charter rate and fuel oil price.

    1995-01-01

    The economic situation of ''Konin'' brown coal mine located in Central Poland is analysed. The main problem of the mine is the coal price which is still regulated despite market economy. It causes many difficulties and therefore a change of energy policy is postulated. The basic economic results for 1993 as well as prognosis of investment costs up to 2020 are given. The changes of management system and the strategy planning training are also described. 2 ills, 1 tab

  9. Crude oil prices : how high, how much harm?

    International Nuclear Information System (INIS)

    Levesque, M.; Alexander, C.

    2002-01-01

    This paper discussed the issue of crude oil prices and the economy. Crude oil prices are on the rise due to the recent events in the Middle East. In early April, West Texas Intermediate crude oil climbed to nearly US$28 a barrel. Most of the increase reflects the expectation of stronger world oil demand combined with supply constraints on the part of OPEC. Although there has been some concern expressed that rising oil prices may hinder economic recovery, the authors of this report do not see evidence that rising oil prices would throw economic recovery off course, arguing that the current spike will be short-lived. They stated that even under a worse-case scenario where prices remain inflated, there is little reason to fear for the health of the Canadian economy. OPEC is expected to increase its low production quotas in June. In addition, non-OPEC nations (Russia in particular) are expected to increase oil production in the coming months. The authors also indicated that it is unlikely that conflict in the West Bank will disrupt oil supply because Israel is not an oil-exporting nation. However, oil supply could be affected if other Arab nations were drawn into the issue. It was also noted that military action against Iraq would increase oil prices, possibly as high as US$40 a barrel, but the full extent of this hike in price will probably be unsustainable. In addition, the authors emphasized that the increase in energy costs would not be enough to seriously jeopardize the economic recovery in the United States. As for Canada, it is estimated that a US$10 per barrel increase in crude oil prices would have a small, but positive impact on Canadian GDP because in contrast to the United States, Canada produces much more energy than it consumers. In 2001, Canada ran a trade surplus of $2.8 billion. The report ended by stating that although higher oil prices could add a full percentage point to headline inflation by the end of the year, core inflation is likely to remain

    Hydrogenolysis of different rank coals as Taiheiyo coal (75.7C%) and Pittston coal (85.4C%) were conducted in the presence of four kinds of catalysts (CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3) with an addition of tetralin as vehicle. The variation in viscosity in every reaction system was traced in the initial stage of the reaction by a torque meter attached to an autoclave. As a result, in every system, the torque decreased in the initial stage of temperature rise because of reduction of a solvent viscosity. The torque subsequently increased with temperature indicating two peaks before the following gradual decrease. In Taiheiyo coal, both peaks were low, and its coal conversion was more than 85%, while in Pittston coal, both peaks were sharp and high, and both subsequent torque reduction and coal conversion were smaller than those of Taiheiyo coal. 5 refs., 10 figs., 2 tabs.

    After a stable or declining real trend that persisted for more than half a century, Australian retail electricity prices have experienced a substantial increase, in real terms, since 2007. This has mainly been driven by increases in the cost of electricity distribution and to a lesser degree in the cost of electricity generation. Reducing greenhouse gas emissions, which is a bipartisan political goal in Australia, will likely deliver further increases in generation costs due to the expected higher cost of low emission technology. Participating in global negotiations on emission reduction targets and designing efficient policy mechanisms have been a major focus of governments over the last several decades. In contrast, managing distribution system costs has received less attention. While there were a number of factors which drove historical increases in distribution costs, management of peak demand growth could help contain or reduce the extent to which consumers, particularly households, experience further increases in distribution costs. The paper demonstrates how different combinations of carbon price and peak demand scenarios could impact future residential and industrial retail electricity prices to 2050 and discusses some behavioural and technological solutions to manage peak demand and potential barriers to their deployment. - Highlights: • We identify the causes of the increase in Australian retail electricity prices. • We identify two sources of likely further cost pressures on electricity prices. • We estimate future retail electricity prices under five scenarios. • We discuss barriers and solutions to controlling peak demand growth.

    This paper describes a technique to evaluate the severity of slagging of a coal in a pulverised-coal-fired boiler. There are few data in the literature on the nature of in-situ boiler slags, their rate of growth and/or their strength properties relevant to sootblowing. The latter is thought to be of more concern to boiler operators and gives rise to the significance of selecting suitable strength tests. As well as standardised methods for characterising pulverised coal performance in a boiler, several novel and less popular techniques are discussed in detail. A suite of three sub-bituminous coals from the Callide Coalfields, Biloela (600 km north of Brisbane), has been selected for slagging tests in the 350 MW{sub e} units of Callide 'B' power station. Disposable air-cooled mild steel slagging probes have been constructed to simulate the conditions for deposit formation in the boiler region. To date, tests for one of these coals has been completed and preliminary results are presented. Once testing for the remaining coals has been completed, it is anticipated that the differences exhibited in deposit growth and strength may be correlated with typical variations in physical and chemical properties of the pulverised coal.

    We assess the option to install a carbon capture and storage (CCS) unit in a coal-fired power plant operating in a carbon-constrained environment. We consider two sources of risk, namely the price of emission allowance and the price of the electricity output. First we analyse the performance of the EU market for CO 2 emission allowances. Specifically, we focus on the contracts maturing in the Kyoto Protocol's first commitment period (2008 to 2012) and calibrate the underlying parameters of the allowance price process. Then we refer to the Spanish wholesale electricity market and calibrate the parameters of the electricity price process. We use a two-dimensional binomial lattice to derive the optimal investment rule. In particular, we obtain the trigger allowance prices above which it is optimal to install the capture unit immediately. We further analyse the effect of changes in several variables on these critical prices, among them allowance price volatility and a hypothetical government subsidy. We conclude that, at current permit prices, immediate installation does not seem justified from a financial point of view. This need not be the case, though, if carbon market parameters change dramatically, carbon capture technology undergoes significant improvements, and/or a specific governmental policy to promote these units is adopted.

    An assessment of price trends suggests continuing rise in 2001, with some easing of upward price movement in 2002 and 2003. Storage levels as of Nov. 1, 2000 are expected to be at 2.77 Tcf, but if the winter of 2000/2001 proves to be more severe than usual, inventory levels could sink as low as 500 Bcf by April 1, 2001. With increasing demand for natural gas for non-utility electric power generation the major challenge will be to achieve significant supply growth, which means increased developmental drilling and inventory draw-downs, as well as more exploratory drilling in deepwater and frontier regions. Absence of a significant supply response by next summer will affect both growth in demand and in price levels, and the increased demand for electric generation in the summer will create a flatter consumption profile, erasing the traditional summer/winter spread in consumption, further intensifying price volatility. Managing price fluctuations is the second biggest challenge (after potential supply problems) facing the industry

    2008-01-01

    The Australian coal industry is an export oriented industry, meeting world needs as a secure, reliable and competitive supplier of high quality coal. It is also the world's largest exporter, with 30 per cent of world coal market. An overview of the Australian coal industry and the impacts of coal infrastructure bottlenecks were addressed in this presentation, with particular reference to demurrage; shipping costs; lost profit and income for coal companies; costs to end users; lost royalties; lost income for infrastructure providers; and higher shipping costs. Perspectives from 2002 were illustrated in graph format, including thermal and metallurgical coal prices; forecast for world coal imports; and forecasted global demand versus actual demand. Other contributing factors to capacity constraints include the underperformance of coal infrastructure supply chains and investment issues. Australia's infrastructure response required a coordinated response between the federal government, state government, mining companies, shippers and buyers, port authorities, Australian Rail Track Corporation, coal terminal operators, and private and public rail freight operators. The presentation concluded with a discussion of the Australian infrastructure response, such as supply side improvement strategies, demand management strategies, and investment in increased infrastructure capacity. It was concluded that infrastructure issues must be addressed on a system wide basis. tabs., figs

    Polish energy sector is facing a number of challenges, in particular as regards the reconstruction of production potential, diversification of energy sources, environmental issues, adequate fuels supplies and other. Mandatory implementation of Europe 2020 strategy in terms of “3x20” targets (20% reduction of greenhouse gases, 20% of energy from renewable sources, and 20% increase of efficiency in energy production) requires fast decision, which have to be coordinated with energetic safety issues, increasing demands for electric energy, and other factors. In Poland almost 80% of power is installed in coal fired power plants and energy from hard coals is relatively less expensive than from other sources, especially renewable. The most of renewable energy sources power plants are unable to generate power in amounts which can be competitive with coal fires power stations and are highly expensive, what leads o high prices of electric energy. Alternatively, new generation of coal fired coal power plants is able to significantly increase efficiency, reduce carbon dioxide emission, and generate less expensive electric power in amounts adequate to the demands of a country.

    Previous studies have found evidence of asymmetric price adjustment in U.S. retail gasoline prices in that gasoline prices rise more rapidly in response to a cost increase than fall in response to a cost decrease. By estimating a threshold cointegration model that allows for multiple regimes, I am able to test how sensitive this result is to outlying observations. In contrast to previous studies, I find little evidence of asymmetry for the vast majority of observations and that the asymmetry is being driven by a small number of outlying observations. (author)

  19. The effects of a rise in cigarette price on cigarette consumption, tobacco taxation revenues, and of smoking-related deaths in 28 EU countries-- applying threshold regression modelling

    Full Text Available Abstract Background European Union public healthcare expenditure on treating smoking and attributable diseases is estimated at over €25bn annually. The reduction of tobacco consumption has thus become one of the major social policies of the EU. This study investigates the effects of price hikes on cigarette consumption, tobacco tax revenues and smoking-caused deaths in 28 EU countries. Methods Employing panel data for the years 2005 to 2014 from Euromonitor International, the World Bank and the World Health Organization, we used income as a threshold variable and applied threshold regression modelling to estimate the elasticity of cigarette prices and to simulate the effect of price fluctuations. Results The results showed that there was an income threshold effect on cigarette prices in the 28 EU countries that had a gross national income (GNI per capita lower than US$5418, with a maximum cigarette price elasticity of −1.227. The results of the simulated analysis showed that a rise of 10% in cigarette price would significantly reduce cigarette consumption as well the total death toll caused by smoking in all the observed countries, but would be most effective in Bulgaria and Romania, followed by Latvia and Poland. Additionally, an increase in the number of MPOWER tobacco control policies at the highest level of achievment would help reduce cigarette consumption. Conclusions It is recommended that all EU countries levy higher tobacco taxes to increase cigarette prices, and thus in effect reduce cigarette consumption. The subsequent increase in tobacco tax revenues would be instrumental in covering expenditures related to tobacco prevention and control programs.

    From the industrial revolution to the 1960's, coal was massively consumed in Europe and its utilization was constantly raised. In the aftermath of World War II, coal had also an important part in reconstruction of Western Europe's economy. However, since the late 1960's, its demand has been declining. There is a (mis)conception from a number of policy makers that saying coal mining and utilizations in Europe is unnecessary. Therefore in the European Union (EU) Green Paper 2000, coal is described as an 'undesirable' fuel and the production of coal on the basis of economic criteria has no prospect. Furthermore, the commitment to the Kyoto Protocol in reducing greenhouse gases emission has aggravated this view. Faced with this situation, the quest for the future of coal industry (mining and utilization) in the lines of an energy policy is unavoidable. This dissertation did a profound inquiry trying to seek answers for several questions: Does the European Union still need coal? If coal is going to play a part in the EU, where should the EU get the coal from? What should be done to diminish negative environmental impacts of coal mining and utilization? and finally in regard to the CO 2 emission concerns, what will the state of the coal industry in the future in the EU? To enhance the analysis, a system dynamic model, called the Dynamics Coal for Europe (the DCE) was developed. The DCE is an Energy-Economy-Environment model. It synthesizes the perspectives of several disciplines, including geology, technology, economy and environment. It integrates several modules including exploration, production, pricing, demand, import and emission. Finally, the model emphasizes the impact of delays and feed-back in both the physical processes and the information and decision-making processes of the system. The calibration process for the DCE shows that the model reproduces past numbers on the scale well for several variables. Based on the results of this calibration process, it can

    The development of Catalytic Multi-Stage Liquefaction (CMSL) at HTI has focused on both bituminous and sub-bituminous coals using laboratory, bench and PDU scale operations. The crude oil equivalent cost of liquid fuels from coal has been curtailed to about $30 per barrel, thus achieving over 30% reduction in the price that was evaluated for the liquefaction technologies demonstrated in the late seventies and early eighties. Contrary to the common belief, the new generation of catalytic multistage coal liquefaction process is environmentally very benign and can produce clean, premium distillates with a very low (<10ppm) heteroatoms content. The HTI Staff has been involved over the years in process development and has made significant improvements in the CMSL processing of coals. A 24 month program (extended to September 30, 1995) to study novel concepts, using a continuous bench scale Catalytic Multi-Stage unit (30kg coal/day), has been initiated since December, 1992. This program consists of ten bench-scale operations supported by Laboratory Studies, Modelling, Process Simulation and Economic Assessments. The Catalytic Multi-Stage Liquefaction is a continuation of the second generation yields using a low/high temperature approach. This paper covers work performed between October 1994- August 1995, especially results obtained from the microautoclave support activities and the bench-scale operations for runs CMSL-08 and CMSL-09, during which, coal and the plastic components for municipal solid wastes (MSW) such as high density polyethylene (HDPE)m, polypropylene (PP), polystyrene (PS), and polythylene terphthlate (PET) were coprocessed.

    The price difference (spread) between power coal and natural gas has increased sharply since 1999. This gap reached its peak in 2013 with 171 Euro/t SKE. In many cases, higher CO{sub 2} prices were required to promote gas use in the electricity sector. However, it has now become clear that falling gas prices lead to a growing competitiveness of natural gas. Interventions in the EU-ETS or at the national level with the aim to promote gas use in the electricity sector do not make sense and would merely reduce the competitive pressure on the gas producers and lead them to become a monopoly rents. [German] Der Preisabstand (Spread) zwischen Kraftwerkskohle und Erdgas stieg seit 1999 stark an. Dieser Gap erreichte in 2013 mit 171 Euro/t SKE seinen Hoechststand. Vielfach wurden hoehere CO{sub 2}-Preise gefordert, um den Gaseinsatz im Stromsektor zu foerdern. Doch inzwischen zeigt sich, dass fallende Gaspreise zu einer wachsenden Wettbewerbsfaehigkeit von Erdgas fuehren. Interventionen in das EU-ETS oder auf nationaler Ebene mit dem Ziel, den Gaseinsatz im Stromsektor zu foerdern, machen daher keinen Sinn und wuerden lediglich den Wettbewerbsdruck auf die Gasproduzenten mindern sowie fuer diese zu einer Monopolrente fuehren.

  3. Maximizing efficiency in the transition to a coal-based economy

    Energy is the lynchpin of modern society. Since the early 1970s, growing dependence on foreign energy sources, oil in particular, has constrained US independence in foreign policy, and at times, inhibited economic stability and growth. Addressing oil dependence is politically and economically complex. Proposed solutions are multifaceted with various objectives such as energy efficiency and resource substitution. One solution is the partial transition from an oil- to coal-based economy. A number of facts support this solution including vast coal reserves in the US and the relative price stability of coal. However, several roadblocks exist. These include uncertain recoverable reserves and the immaturity of 'clean' coal technologies. This paper provides a first order analysis of the most efficient use of coal assuming the transition from oil to coal is desirable. Scenario analysis indicates two possible transition pathways: (1) bring the transportation sector onto the electric grid and (2) use coal-to-liquid fuels to directly power vehicles. The feasibility of each pathway is examined based on economic and environmental factors, among which are energy availability, affordability and efficiency, and environmental sustainability. Results indicate that partial transition of the transportation sector onto the electric grid offers the more viable solution for coal-based reduction of the US oil dependence.

    The objective of this report is to give a synthesis of different points of view with respect to the 'Peak Oil' perspective and to the crude oil price evolution. In the first part, the authors examine the evolutions and assessments of oil reserves and productions, by discussing the different types of reserve, the optimistic and pessimistic points of views. Then, in the second part, they analyse the long term price formation, the various production technical costs (conventional oils, heavy oils and asphaltic sands, coal- and gas-based synthetic hydrocarbons, bio-fuels), the external costs (notably in relationship with greenhouse emissions), the relationship between geopolitical issues and short and middle term price formation. In the third and last part, they discuss the possible evolutions and scenarios in terms of demand, production, and prices

    The eighth in a series of oil price expectation studies took place on 18th March 1992 at the Prospects for Oil Prices conference held at the University of Surrey. Thirty-one participants returned a questionnaire designed to elicit 12 month ahead and 5 year ahead price expectations. Respondents were asked to indicate their view of the likely price of oil in certain broad price ranges. These were selected to cover the wide variation of prices experienced since the early 1970s. The results show the 12 month's ahead expectations all clustered in the range $10 to $25 per barrel and $16-$20 as the median predicted price. In comparison with the 1991 expectations, a much higher proportion of respondents (77.4 as compared to 50% in 1991) gave $16-20 as their expected price range, whilst fewer expected prices to rise (19% compared with 46% in 1991). The stability of the 12 month ahead price expectations is a remarkable feature of a period which has witnessed much tension in the Middle East and in the former Soviet Union. This stability extends to the 5 year ahead forecasts as well. Here the median expectation is for prices to rise to the $21-25 per barrel range in money of the day terms though there is evidence of a growing scepticism about the oil market's ability to sustain higher prices in the long run.

    The prices of fuels in the international markets affect the development of consumer prices of energy in Finland. In the near future no factors can be foreseen, which would cause major increases in the prices of oil, coal or gas. It can thus not be expected that increased fuel prices would motivate more efficient energy conservation. In international comparison, consumer prices of energy have been relatively low in Finland. This applies especially to electricity. After the removal of price controls, energy prices have been determined by the markets. The influence of the public authorities in energy pricing is put into effect through taxation. The price of energy has a fairly small effect on energy consumption in a short term, but longer term effects are more significant. Energy products are faxed in all western countries. (orig.)

    This report describes the effective utilization of coal ash discharged from general industry (general industry ash) as improving material of construction waste soil and deodorant for poultry industry. Coal ash is characterized by the pozzolan and self-hardening properties which are not shown in soil and sand. Coal ash having a large amount of free CaO in its composition has stronger such properties. Coal ash generated from fluidized bed combustor which is a kind of combustor of coal contains a large amount of free CaO, especially, resulting in the stronger such properties. On the other hand, coal ash has water and oil absorbing property due to its porous structure. To utilize these properties, the improving material of soft construction waste soil and deodorant for poultry industry have been selected. As a result of laboratory and field tests for the former, it was found that sufficient supporting force can be obtained. Since the protection of powder splash is required at the site, a humidification system has been developed, which can protect the splash by the humidification of 5%. The price between 500 and 1,000 yen/ton is suitable for the improving material of construction waste soil. The maximum price of the deodorant for poultry industry is 10 yen/kg. 14 refs., 40 figs., 49 tabs.

    Forecasting work carried out by a number of institutions shows how difficult it is to accurately predict trends in oil prices. The authors of this report do not carry out this forecasting exercise, but they share the same conclusions about the main features of oil price trends in the near and medium term: a rise in oil prices is inevitable, and will be accompanied by significant volatility. This expectation is based on detailed analysis of oil price determinants, their past variations and forecasts as to their future trends. On the supply side, like with all goods, the price of oil reflects production costs: extraction, transport and refining costs. Alongside this essentially technological component, more specific determinants are at play: the noncompetitive economic rent, which largely stems from OPEC's hold on the market, the scarcity rent on all non-renewable natural resources (this rent increases at a rate equal to the real interest rate according to Hotelling's rule), various taxes (mainly the TIPP domestic tax on oil products in France) and a new component that is set to gain importance in the years ahead, namely the implicit price of carbon emissions (which may take the form of a carbon tax or the cost of emission permits). It is difficult to isolate these different components and even more difficult to quantify them, but the authors' detailed analysis shows that most predictable supply-side developments will concur to bring about a rise in oil prices. On the demand side, too, forecasts and projections converge towards a rise in oil prices. Demand trends depend on crude oil prices, taxes, economic growth and energy and environmental policies. In most developed countries, the trend is towards a slowdown in demand growth and some countries are even seeing a decline in demand. In addition to the economic crisis, two explanations are put forward. The levels reached by crude oil and fuel prices in July 2008 clearly brought the price-elasticity of

    2016-01-01

    Full Text Available This paper focuses on state intervention in the pricing of electricity from renewable power sources in the Czech Republic when compared with the pricing in the Slovak Republic, Germany, France and Italy. In these countries the state intervention is implemented in different forms, but the critical part of the price is regulated everywhere by the state. The price of electricity is determined by its production costs, which depend on the source from which electricity is produced. The highest cost of electricity is required to generate renewable energy, particularly solar power, while the lowest costs of power are associated with its production by coal-fired and natural gas-fired thermal power plants. However, hydroelectric power plants attain clearly the lowest cost for generating electricity. State intervention includes supporting power generation from renewable power sources by guaranteeing purchase prices.

    1980-01-01

    This paper explains the basic strategies which may be applied in the exploitation of coal deposits by underground mining. It outlines the importance of combinations of extensive (non-mechanized) and intensive (mechanized) exploitation and their dependence on coal demand, available financial means, requirements concerning the protection of environment, unemployment of the population, availability of mechanical and electrical equipment, technical staff, etc. It is suggested that the applied strategy be revised and adapted to the current situation. Postponement of exploitation until the future when the demand and price of coal may be higher is criticized. The possibility of applying extensive underground mining in areas where unemployment and lack of capital speak against the application of fully mechanized working methods is also dealt with.

    2017-07-01

    Global development of Underground Coal Gasification (UCG) is considered here in light of latest trends of energy markets and environmental regulations in the countries that have been traditional proponents of UCG. The latest period of UCG development triggered by initial success of the Chinchilla UCG project (1997-2006) has been characterized by preponderance of privately and share-market funded developments. The deceleration of UCG commercialization has been in part caused by recent significant decrease of world oil, gas and coal prices. Another substantial factor was lack of necessary regulations governing extraction and conversion of coal by UCG method in the jurisdictions where the UCG projects were proposed and developed. Along with these objective causes there seem to have been more subjective and technical reasons for a slowdown or cancelation of several significant UCG projects, including low efficiency, poor environmental performance, and inability to demonstrate technology at a sufficient scale and/or at a competitive cost. Latest proposals for UCG projects are briefly reviewed.

    World demand for gas is expected to rocket, yet future natural gas and liquefied natural gas projects remain threatened by the link of gas prices to crude oil prices. This is the main message that emerged from the 19th World Gas Conference in Milan last week. A number of reports predicted regional demand for gas. All foresaw a rise. International Gas Union (IGU), organizer of the conference, and said world natural gas production has continued to rise despite a significant downturn in industrial production. The paper discusses gas demand in Europe, the correlation between oil and gas prices, the natural gas industry in Indonesia, Russia, and southern Europe

    A scenario with higher oil prices has important implications for diverting from oil-based technologies to renewables, as well as gas, coal, and nuclear alternatives. By 2030, energy demand in Latin America and the Caribbean (LAC) is expected to double from 2008 levels. A key issue is deciding on the most appropriate mix of fuels for power generation, given the various prices of energy sour...

    Alberta is a province in western Canada with a deregulated electricity-market. Market clearing prices for most hours reflect the cost of either coal-fired or gas-fired thermal generation. Whenever there is a chronic shortage of generation or even a temporary one due to an outage, prices can be bid much higher than fuel costs would suggest. The province of British Columbia borders Alberta to the west and its electric utility, BC Hydro, has a history of trade with the utilities in Alberta. BC Hydro has predominantly hydroelectric resources and large storage reservoirs. Prior to Alberta's deregulation in 1996, BC Hydro was able to enter into mutually beneficial load-factoring contracts with the Alberta utilities. Now, as long as the transmission is available, BC Hydro can buy low priced off-peak coal-fired energy and sell into the high priced periods without having to share the benefits. BC Hydro uses a combination of econometric and Monte Carlo modelling to simulate hourly price-duration curves for Alberta that capture both cost-based and bid-based characteristics. This approach provides a good fit with the stochastic dynamic programming model that BC Hydro has developed for its mid-term hydro scheduling. (author)

    Highlights: • Demand response to energy price signals in energy consumption in Beijing is studied. • The electricity price is of great importance to Beijing’s energy market stability. • Industrial sectors have a large electricity self-elasticity and cross-elasticity. • When consuming electricity, customers pay more attention to natural gas price. • Analysis of demand response to energy price can provide guidance to energy policies. - Abstract: The energy price system in Beijing has not fully exploited customers’ price elasticity, and has a negative impact on achieving the goals of energy saving. This paper analyses the response behaviours of different customers to typical energy prices. As for electricity self-elasticity, the range of the primary, secondary, tertiary industry and residents are −0.026 to −0.033, −0.045 to −0.059, −0.035 to −0.047 and −0.024 to −0.032, respectively. As regards self-elasticity on coal, the range of the primary, secondary, tertiary industry and residents are −0.030 to −0.037, −0.066 to −0.093, −0.055 to −0.072 and −0.034 to −0.051, respectively. The self-elasticities on oil and natural gas are very weak. As for cross-elasticity, when consuming electricity and oil, customers mainly focus on the prices of natural gas, which are 0.185 and 0.112. When consuming coal and natural gas, customers are concerned about the electricity prices, and their cross-elasticities are 0.03 and 0.36, respectively. The estimation of demand response to energy price signals in energy consumption behaviours can provide a decision support for formulating rational energy price policies

    National health care expenditures are rising rapidly, bringing on a health care financing crisis. For this reason, it is useful to see how hospitals are facing the price issues of the 1990's. This study examines the price strategies hospitals follow and analyzes their observations on price sensitivity and payer mix. The results clearly show that hospitals have not given much attention to the pricing variable. The study suggests that marketing and finance will have to work closely together in developing future pricing strategies.

    In the last twelve years the share of natural gas in the total consumption of primary energy has increased twelve-fold and now amounts to 16 per cent. One-third of this is produced in West Germany. Although world deposits will last well into the next century, attempts are already being made to perfect techniques for obtaining gas from coal. However, the cubic metre price of synthetic gas is still anything but competitive.

    That aim of this paper is to compare trends in global, European use of coal with tendencies in Poland, one of heavy coal dependent countries. Polish power generation is unique among OECD countries, the share of both hard coal and lignite in power generation reaches 81% [1]. Climate policy of European Union is to phase out intensive greenhouse gases sectors, thus to transform Polish power generation into less carbon intensive. Although such policy is generally accepted in Poland, the paste and practically proposed regulation that excludes coal generation from capacity mechanisms, is considered as threat to energy security. Coal is the base for generation for one simple reason, abundant in European scale hard coal reserves and significant capacities in lignite. Natural gas reserves allow to supply about 1/3 of consumption, but prices and supplies dependent hitherto on contracts with GAZPROM did not allow to develop significant generation capacities. Renewable resources are limited, there is not much possibilities for hydro, wind and solar. Poland is also one of the countries of poor air quality, traditional coal based space heating systems plus obsolete car fleet generate vast emissions, especially during the winter. Only recently this became top priority of environmental authorities. This situation is subject to transformation, government, managers are aware that the role of coal needs to be decreased, but there are two main questions, the paste of transformation and the future energy mix. The paper attempts to answer the question whether the expected changes in Polish energy mix are comparable or differ from the global and European tendencies.
