The development of market power in the Polish power generation sector: A 10-year perspective

International Nuclear Information System (INIS)

Kamiński, Jacek

2012-01-01

The paper examines how and to which extent consolidation in the Polish power generation sector has affected the potential for market power over the last 10 years. Although this sector has been undergoing liberalisation (privatisation, introduction of TPA regulations and competition etc.), the consolidation efforts shown by Polish governments have resulted in a significant increase in concentration of both installed capacity and production. The methodology applied in this study includes typical ex-post structural and behavioural measures employed to estimate potential for market power, namely: concentration ratios (for the largest and the three largest suppliers), the Herfindahl–Hirschman Index, entropy, Supply Margin Assessment, the Residual Supply Index and the Lerner Index. Furthermore, an analysis based on the Gini coefficient was employed to obtain an insight into inequalities. The results of this study show that governmental decisions led to a significant increase in the potential to exercise market power held by key power generation companies. Of key importance was the 2007 consolidation, resulting in an increase in the HHI to 1374 (in terms of installed capacity) and 1945 (in terms of electricity production). This consolidation resulted in the creation of the first Pivotal Supplier in the Polish power generation sector in 2008. - Highlights: ► Market power analysis based on structural and behavioural indices was carried out for the Polish power sector. ► Governmental policy resulted in significant increase in concentration of both installed capacity and generation. ► Increase in the Lerner Index of brown coal-based generation and decrease of the hard coal-based one were observed.

Competition within the energy sector and State regulation

Larsen, A.; Jess Olsen, O.

It is presumed that energy markets will be liberalized. Questions discussed are how the Danish electricity and gas sectors are to be re-regulated in order to ensure that this goal is reached in the most satisfactory manner (cheaper energy supply under competitive conditions) and whether there will be a conflict between the goal of liberalization and the environmental goals of clean technology and energy conservation. It is suggested that a compulsory splitting up of the two regional power associations in Denmark should not be necessary. Transmission and distribution must continue to be regulated as these are natural monopolies not compatible with competition. District heating will still be a monopoly and its prices must be closely regulated to prevent soaring. The opening up of the European gas market to competition will threaten Danish energy utilities. The increasing compulsory use of natural gas in cogeneration plants to politically determined high prices is not sustainable under competitive conditions. Energy saving activities should not be affected. Energy surcharges are attractive measures on a liberalized market. The regulation of competition ought to be incorporated explicitly as a restriction in the Ministry of Energy's energy policy regulation. Energy utilities could be excluded from participation in price setting. International regulation of competition will demand a clarification of the separation of regulatory competence between the member states and the European Commission. It will also be necessary to adjust the Danish regulation of the electricity sector to the future Scandinavian system. (AB) 77 refs

According to a new report by CEDIGAZ, the International Centre for Natural Gas Information, gas has lost its attractiveness against coal in the EU power sector. Its demand by the sector decreased by one third during the past three years and its prospects are very weak in this decade. The Association warns that un-profitability of combined cycle gas turbines (CCGTs) and the retirement of old coal plants due to stringent air regulation may lead to the closure of one third of the current fleet and poses a serious security of supply issue that has to be addressed urgently

Restructuring of the Bulgaria power sector - changes and risks

Petrov, K.

1999-01-01

On the base of the analysis made by KEMA Consulting GmbH, Germany in 1998 - 1999 according to the project 'Aid for the development of the power authority in Bulgaria' some of the possibilities and risks for the new organization are discussed. Currently the National Electric Company is a monopolist in the electricity production sector. The government policy is aimed to efficiency improvement, creation a competition where possible, expanding of the private sector. The reconstruction is based on the model of 'the single customer'. Disadvantages are: insufficient competition, centralized planning and inappropriate risk distribution, necessity of a comprehensive regulatory control. The advantages of the method are: smooth transition to the new structures, separation of the monopole and competition functions, clear predictability of the purchases, competition of new capacities. The recommendations include urgent developing of system rules, conclusion of short-term agreements for power purchase, preparation for introduction of open access and development of the Government Agency for Power Regulation

Nigeria has been plagued with acute power shortages due to poor performance of its power sector. Several policies and reforms have been implemented by the government to address the poor performance of the power generation, transmission and distribution sectors of the electricity industry. Also various strategies were employed by the government which includes encouraging private sector participation, diversification of the energy generation sources and promoting energy efficiency for sustainable development. In addition the government has spent billions of dollars since 2001 in the construction of new power generation facilities, transmission lines and distribution centers to boost the power supply. It has deregulated the generation and distribution sectors to encourage private sector participation and empowers the Energy Commission of Nigeria to embark on programs and strategies that can boost energy generation from renewable sources. This paper examined the country's energy sources and the power sector reforms adopted by the government. The paper also outlined some recommendations based on reforms implemented by other countries with similar resources to Nigeria which yielded positive results. - Highlights: • Available resources for power generation in Nigeria. • Power sector challenges, policies and reforms. • Implications of the reforms implemented. • Recommendations for improving the sector's performance.

Competition, regulation, and energy efficiency options in the electricity sector: Opportunities and challenges in developing countries

Science.gov (United States)

Phadke, Amol Anant

This dissertation explores issues related to competition in and regulation of electricity sectors in developing countries on the backdrop of fundamental reforms in their electricity sectors. In most cases, electricity sector reforms promoted privatization based on the rationale that it will lower prices and improve quality. In Chapter 2, I analyze this rationale by examining the stated capital cost of independent (private) power producer's (IPPs) power projects in eight developing countries and find that the stated capital cost of projects selected via competitive bidding is on an average about 40% to 60% lower than that of the projects selected via negotiations, which, I argue, represents the extent to which the costs of negotiated projects are overstated. My results indicate that the policy of promoting private sector without an adequate focus on improving competition or regulation has not worked in most cases in terms of getting competitively priced private sector projects. Given the importance of facilitating effective competition or regulation, In Chapter 3, I examine the challenges and opportunities of establishing a competitive wholesale electricity market in a developing country context. I model a potential wholesale electricity market in Maharashtra (MH) state, India and find that it would be robustly competitive even in a situation of up-to five percent of supply shortage, when opportunities for demand response are combined with policies such as divestiture and requiring long-term contracts. My results indicate that with appropriate policies, some developing countries could establish competitive wholesale electricity markets. In Chapter 4, I focus on the demand side and analyze the cost effectiveness of improving end-use efficiency in an electricity sector with subsidized tariffs and electricity shortages and show that they offer the least expensive way of reducing shortages in Maharashtra State, India. In Chapter 5, I examine the costs of reducing carbon

In September 2005, AFD's Research Department launched a Research Program on Public Private Partnerships with an approach combining economic analysis (contractual incentives, financing of investment, etc.) with a sociological and political approach to regulatory issues. Various case studies have been conducted in different sectors (water and sanitation, power, transport) and countries. This study falls within the above research framework since India - like most major developing countries - has attempted to introduce market forces in its electric power systems. At the same time, growing concern over global climate change has put the spotlight on the need for India to control its emissions of greenhouse gases (GHG). India is currently the world's sixth biggest producer of GHG emissions, but is the second biggest if one considers the rate of augmentation of its emissions. Half of India's total GHG emissions are produced by its power sector, and 70 per cent of electricity is generated by thermal power plants, mainly from coal. Climate change mitigation in the power sector is thus a strategic issue for AFD in India. This study is structured so as to examine the intersection of these two crucial challenges in India by exploring the links between private participation in the power sector in India and the reduction of GHG emissions

Nuclear power and the private sector

International Nuclear Information System (INIS)

Miller, D.J.

1989-01-01

The world scene is sketched in which nuclear power already contributes 600 Mtce/year to world energy but where public attitudes in the developed world have become largely hostile. This is despite the proven technology of nuclear power, its safety record (Chernobyl notwithstanding) and its environmentally benign aspects. The United Kingdom government's determination to ensure a continuing role for nuclear power in a privatized electricity supply industry is seen against this background. The structure of the British nuclear power industry undoubtedly presents difficulties for privatization but solutions are available and precedents for private sector nuclear power exist in other countries. Private sector operators will be required to meet the exacting standards set by the independent licensing authority but in view of the public concern redoubled efforts and new approaches will be necessary in public persuasion. Waste disposal is another issue which may have implications for the acceptability of nuclear power in the public sector. Finally, the prospects for investment in new nuclear plant by private generation companies are examined. (U.K.)

When the Single Market comes into operation, the author claims, vertically integrated, national and regional monopolies within the electric power sector will be abolished. The nature of the new organization of this sector is as yet unclear. The Nordic countries are beginning to prepare themselves for the new situation. The subject of the article is this prospective development and some of the problems that will arise for the Nordic countries in this respect. The various Nordic proposals and their background are described in addition to the present conditions within the Nordic electric power sector. The special problems which may arise in relation to the Nordic adaption to the Single Market, the forms of adaption that are already beginning (adaptions of regulations, legal aspects etc.) on the part of the authorities and the electric power companies' attitudes and adaptions to expected future conditions are elucidated.

Gas and coal competition in the EU Power Sector

International Nuclear Information System (INIS)

Cornot-Gandolphe, Sylvie

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

Empirical Assessment on Financial Regulations and Banking Sector Performance

Directory of Open Access Journals (Sweden)

Igbinosa S.

2017-09-01

Full Text Available This study examines financial regulation and banking sector performance in Nigeria. Specifically, the study determines the impact of reforms on banking sector performance and also assesses the nexus between capital adequacy and banking sector performance. Time series data for the period 1993 to 2014 was used. As an analytical tool, the study uses unit root test to determine the stationary state of the variables. We also employed the Johansson co-integration and error correction model (ECM statistical techniques to establish both short-run and long-run dynamic relationships between the endogenous and exogenous variables. The empirical findings indicate that financial regulation significantly impacts the banking sector performance while financial regulation has both short-run and long-run dynamic relationships with the banking sector performance in Nigeria. It was found that the four-period lag of capital adequacy negatively affects banking sector performance and is not statistically significant. The paper suggests that the Central Bank of Nigeria (CBN should continually make public the impacts that the various financial regulations and reforms have on the performance of Nigerian banks. Majority of the policies on financial regulation by the apex bank (CBN need to be long-run which can enable confidence of stakeholders, shareholders and the general public in the Nigerian banking industry when critically evaluated.

Power sector reform in India: current issues and prospects

International Nuclear Information System (INIS)

Singh, Anoop

2006-01-01

Power sector reforms in India were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden. Investment in the sector was not able to keep pace with growing demand for electricity. This paper takes stock of pre-reform situation in Indian power sector and identifies key concerns that led to initiation of the process of reform. The paper discusses major policy and regulatory changes undertaken since the early 1990s. The paper also illustrates changes in the market structure as we move along the reform process. We also discuss some of the major provisions of the recently enacted Electricity Act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country. In this context, we discuss two issues arising out of it, namely open access and multi-year tariff that we think would have a significant bearing on the performance of the sector in the near future. The paper also evaluates the reform process in the light of some of the regulatory changes undertaken. Finally, the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

Integrating competition and planning: A mixed institutional model of the Brazilian electric power sector

International Nuclear Information System (INIS)

Bajay, S.V.

2006-01-01

During the past decade, the Brazilian electric power sector went through similar institutional changes taken place in both developing and developed countries. The main goals for such changes were to inject competition into the generation and supply links of the sector's production chain and to reduce public debt via privatization of state-owned utilities that dominated the pre-reform sector. This paper discusses why these changes took place in Brazil and explains why the results of the reform model implemented by the previous federal administration were unsatisfactory. The current federal administration has substantially altered the prior model, aiming to remedy insufficient private investment in new power stations that caused a serious power shortage in 2001. The paper addresses the main characteristics of the new model, which implements (a) public biddings of new power plants for all distribution utilities in the country, and (b) forward planning of optimal commissioning times and capacity of new plants. The paper ends with a discussion of the potential benefits and drawbacks of the new scheme and the role of the regulator in the early stage of the ongoing transition in the Brazilian electrical power industry.

In Turkey, highest priority is given to domestic resources, whenever economical. Imports are considered in case it is feasible. Diversification of resources is also taken into account. Efficient utilization of the resources and energy conservation are ensured ant supported. Measures for environmental and public health protection are taken into consideration during power generation and planing. In energy investments, foreign capital and domestic private sector are promoted along with the public sector. A rational structure in energy pricing is applied without any subsidies. Feasible interconnections and higher electric power exchanges with neighbouring countries are supported

Access to Power: Governance and Development in the Pakistani Electrical Power Sector

Science.gov (United States)

Naqvi, Ijlal

This dissertation explores governance in Pakistan through a study of the state-run electrical power sector. At both the micro and macro level, the Pakistani power sector provides a lens into the heart of the Pakistani state and its governance institutions. This ethnographic and historical study offers an in-depth look at state operations in a developing country, situates the current Pakistani power crisis in a larger context of continuity through periods of dictatorship and democracy, and suggests how efforts to make state service delivery more responsive to citizens might be reconceived. A historical review of the Pakistani power sector establishes first and foremost that the current crisis is the product of longer-term processes for which the policy solutions currently being proposed (with the support of international donors and multilateral lenders) are inadequate. Depoliticized attempts at power sector reform have little to offer in light of the pervasively informal and negotiated nature of the fragmented Pakistani state. The institutions of power sector governance are mutually constituted by the formal rules and the informal---personal relationships, language, violence, money, and power. These rules of the game are as relevant to relations within and between public sector organizations as they are to the engagement of citizens with their state. The same rules apply at the margins of the state---informal squatter settlements---as at the core, though the resources brought to bear and the resultant outcomes are different. The internal incoherence of this state underscores the limitations of formal rules in determining outcomes, and the poor prospects for reform efforts that focus exclusively on the formal aspects of governance. To proactively engage with the question of political will leads away from top-down policy perspectives and counter to the depoliticizing tendencies that currently shape policy reforms. Instead, an energized and informed local participation

This study explores dynamics related to natural gas use at the national, sectoral, and regional levels, with an emphasis on the power sector. It relies on a data set from SNL Financial to analyze recent trends in the U.S. power sector at the regional level. The research aims to provide decision and policy makers with objective and credible information, data, and analysis that informs their discussions of a rapidly changing energy system landscape. This study also summarizes regional changes in natural gas demand within the power sector. The transition from coal to natural gas is occurring rapidly along the entire eastern portion of the country, but is relatively stagnant in the central and western regions. This uneven shift is occurring due to differences in fuel price costs, renewable energy targets, infrastructure constraints, historical approach to regulation, and other factors across states.

Designing effective power sector reform: A road map for the republic of Georgia

Science.gov (United States)

Kurdgelashvili, Lado

to those in economies of transition. The dissertation provides a guide for policy makers in the energy sector for implementing power sector reform. At first the dissertation offers a general overview of different models of power sector organization, regulatory frameworks and market arrangements, and the potential impact of reform on social welfare. This knowledge is then applied for analysis of power sector reform in the Republic of Georgia. Social welfare analysis (SWA) is a major analytical tool used in the research for assessing the potential impacts of different power sector organization models on various stakeholders. Through the research it was identified that power industry arrangements in different countries have their particularities; however, after some level of simplification, power sector organization models can fit into one of three broad categories: (1) Government control and regulation of generation and retail segments of the power industry. (2) Full scale competition in the generation segment and retail choice. (3) Partial government control of the generation segment and limited retail choice. For SWA of different power market arrangement scenarios, electricity supply and demand curves had to be derived; for this purpose electricity demand forecasting and power supply evaluation methodologies were developed. This dissertation combines SWA, accepted demand forecasting methods and established power supply evaluation techniques to assess power sector performance under specified policy scenarios relevant to the circumstances of economies in transition such as the Republic of Georgia. Detailed analyses are performed for understanding possible outcomes with the introduction of different reform models. In addition, specific options for incorporating sustainable energy alternatives in the energy planning process are identified and assessed in economic, environmental and social terms. Special attention is given to market-based instruments for promoting

Public Benefits and Power Sector Reform. Report from an International Workshop

Nilsson, Lars J.; Arvidson, Anders; Eberhard, Anton (eds.)

2003-10-01

The Workshop on Public Benefits and Power Sector Reform was motivated by the need to address broader development goals and advance the provision of public benefits in power sector reforms. The primary objectives were: To provide a forum for a discussion among specialists, of how the provision of public benefits can be expanded as power sectors in developing countries are reformed, and review the experience (Day 1). To identify the needs for training and capacity building and institutional arrangements, as well as make recommendations for their design and implementation, for policy makers, regulators, and other professionals in developing countries (Day 2). Public benefits is a socially constructed concept that includes activities that are not adequately conceived by competitive markets. Public benefit policies and programmes include those that expand electricity access to rural areas and the urban poor, improve security of supply, promote energy efficiency and renewable energy, etc. Reforms have indeed been a threat to public benefits as traditionally delivered through electric utilities. However, in many cases public benefit programmes have also been rescued. In fewer cases, public benefit programmes have been conceived in the reform process. From experience so far it is clear that power sector reforms must be made more compatible with broader sustainable development goals. Recognising the need for broader policy integration and putting public benefits higher on the reform agenda points to the importance of reaching beyond energy ministries and power sector experts at an early stage in the reform process. Other actors, such as NGOs and academia, may also be instrumental in monitoring and assessing the impacts of reform. Public benefits can be an integral part of a reform package, or a complement to reform. It does appear that reform creates space and opportunity to achieve public benefits, but someone has to utilise that opportunity. The need to make trade

Regulating the for-profit private health sector: lessons from East and Southern Africa.

Doherty, Jane E

2015-03-01

International evidence shows that, if poorly regulated, the private health sector may lead to distortions in the type, quantity, distribution, quality and price of health services, as well as anti-competitive behaviour. This article provides an overview of legislation governing the for-profit private health sector in East and Southern Africa. It identifies major implementation problems and suggests strategies Ministries of Health could adopt to regulate the private sector more effectively and in line with key public health objectives. This qualitative study was based on a document review of existing legislation in the region, and seven semi-structured interviews with individuals selected purposively on the basis of their experience in policymaking and legislation. Legislation was categorized according to its objectives and the level at which it operates. A thematic content analysis was conducted on interview transcripts. Most legislation focuses on controlling the entry of health professionals and organizations into the market. Most countries have not developed adequate legislation around behaviour following entry. Generally the type and quality of services provided by private practitioners and facilities are not well-regulated or monitored. Even where there is specific health insurance regulation, provisions seldom address open enrolment, community rating and comprehensive benefit packages (except in South Africa). There is minimal control of prices. Several countries are updating and improving legislation although, in most cases, this is without the benefit of an overarching policy on the private sector, or reference to wider public health objectives. Policymakers in the East and Southern African region need to embark on a programme of action to strengthen regulatory frameworks and instruments in relation to private health care provision and insurance. They should not underestimate the power of the private health sector to undermine efforts for increased

At independence, most countries in the West Africa sub-region adopted a development strategy which was spearheaded by the public sector. The aims at presenting discussions on some of the major issues on initiating the reform process and issues associated with the transition period. Section 2 looks at the energy resources for power development in the region and section 3 discusses some unsustainable trends in the sector. Section 4 presents the issues and discusses them, and finally, section 5 presents the conclusion and some policy implications. The discussions in the paper stress the point that reforming the power sector in the countries in the region is not simply a question of implementing consultants' recommendations, but rather a process that must be thought through, and also involves bringing all the shareholders along and putting the regulatory system and institution in place to ensure acceptability and implementatibility of the proposed changes. Governments in the region have a responsibility to build the capacity necessary to initiate and manage the reform process in the power sector, and understanding the issues involved will help to adopt the right approach to reforming the sector.

At present, generation, transmission and selling of power in Romania is actually a monopoly of RENEL (The Romanian Electricity Authority). Moreover, RENEL covers an important share of the heat required by the great district heat consumers and industry (steam). Medium and long term programs for RENEL restructuring aims at moving the power distribution and selling sectors out of RENEL and at restructuring the generation sector. The present papers focuses mainly on those issues related to power generation sector privatization meant to promote a real competition in the field of power generation. To reach this purpose new regulations are necessary to ensure the access to the power system of various consumers satisfying certain technical requirements. This regards also all the independent power producers of electricity and possibly of thermal power (for instance the cogeneration power plants with less than or close to 50 MW). At the same time new concepts such as 'contracted power' and 'transit (wiring) tax' should be implemented in the near future in the business relations. Competition in this field will lead to the development of power market and the enhancement of power investments. (author). 3 refs

Regulation and competition issues in Thai electricity sector

International Nuclear Information System (INIS)

Wisuttisak, Pornchai

2012-01-01

This paper explores the issues related to regulatory reform and liberalisation leading toward competition in the Thai electricity sector, which is still under the monopoly control of state-owned enterprises (SOEs). Following an overview of the current market structure of the Thai electricity sector, the process of liberalisation and deregulation that contributes to the uncompetitive market structure under SOEs’ control is examined. The author asserts that there are problems within the Energy Commission and the Energy Industry Act BE 2550 (2007) that contribute to the continuance of an uncompetitive electricity supply. Possible reforms to the Thai electricity regulation are proposed with the aim of creating market competition and efficiency in the Thai electricity sector. - Highlights: ► Author studies on the regulatory reform and a development of liberalisation plans on Thai electricity sector. ► The paper presents that the liberalisation plan was affected by the government implementation on electricity corporatisation. ► The paper asserts that the current energy regulation will not lead to market reform and competition in electricity. ► The paper also discusses on the current monopoly structure of Thai electricity sector under state owned enterprises. ► The paper concludes that Thailand needs an appropriate regulatory reform for building competition in electricity sector.

Power sector development in a common Baltic electricity market. Executive summary

International Nuclear Information System (INIS)

2005-05-01

In the years to come the Baltic electricity sector is expected to go through major changes. up till recently the sector has been characterised by vertically integrated monopolies, but at present the electricity sectors in the Baltic States are undergoing reform processes to meet the requirements of the EU directives regarding liberalisation of electricity sectors. This implies a different organisation of the sector, with new roles and responsibilities, and focus on new issues such as a well-functioning electricity market, security of supply and market power. In this project long-term scenario analyses are used to clarify the challenges facing the future Baltic electricity market and to analyse the robustness of the power sector. The project examines how existing power plants will manage in a competitive market, how power prices will develop and which investments are likely to be preferred by investors, among other issues.

Generating efficiency: The power of price caps in the public and private Spanish electricity sectors

International Nuclear Information System (INIS)

Arocena, P.; Price, C.W.

1999-01-01

Economic regulation of firms with market power has placed increasing emphasis on incentive-based regulation such as price caps. The move to such regulation often coincides with a change of ownership, making it difficult to separate the incentive effects. We focus on the effect of regulation alone by analysing the imposition of price cap type regulation on both publicly and privately owned Spanish electricity generators in 1988, several years before three was any change of ownership. Our initial results indicate that the publicly owned generators are generally more efficient than the private ones, but that the effect of price caps is to increase the efficiency of private sector plants faster than those in the public sector. We introduce two novelties into the analysis: we incorporate levels of CO2 and NOx emissions; and we include declared plant availability as an output. The outcome is dependent on the choice of inputs and outputs, and we argue that our measures are more appropriate than traditional measures for a system of central despatch for generators facing environmental constraints.

2011-07-01

The Indian power sector will face numerous challenges over the next four decades. More than one third of India's population currently do not have access to electricity. Urgent action is needed to overcome this problem of energy poverty. At the same time rapid economic growth is projected to increase electricity demand by fivefold to sixfold between now and 2050. Massive investments will be needed to meet this increased demand, but this will also create unique opportunities to transform the power sector towards a low-carbon future. This Information Paper presents in more detail the analysis for India published in Energy Technology Perspectives 2010. The paper investigates the best way of achieving deep CO2 emission cuts in the Indian power system while allowing the Indian economy to continue growing and meeting the challenge of alleviating energy poverty. It does so from a techno-economic perspective - building on detailed resource and technology data for India - and identifies the key power sector technologies needed for India to realise such a transition.

The offshore trend: Structural changes in the wind power sector

International Nuclear Information System (INIS)

Markard, Jochen; Petersen, Regula

2009-01-01

In recent years, the wind power sector has begun to move offshore, i.e. to use space and good wind speeds on the open sea for large scale electricity generation. Offshore wind power, however, is not just technologically challenging but also a capital intensive and risky business that requires particular financial and organizational resources not all potential investors might have. We therefore address the question, what impact offshore wind power may have on ownership and organizational structures in the wind power sector. We compare on- and offshore wind park ownership in Denmark, the UK and Germany. The analysis shows that offshore wind power in all three countries is dominated by large firms, many of which are from the electricity sector. In Denmark and the UK, also investors from the gas and oil industry play an important role in the offshore wind business. This development represents a major shift for countries such as Germany and Denmark, in which the wind power sector has grown and matured on the basis of investments by individuals, farmers, cooperatives and independent project developers. The structural changes by which offshore wind power is accompanied have consequences for turbine manufacturers, project developers, investors, associations and policy makers in the field.

Directory of Open Access Journals (Sweden)

Coralia Angelescu

2006-10-01

Full Text Available This study provides a methodological analysis to evaluate the regulation strategy in Romanian natural gas sector. The market oriented reforms are not only associated with the gap between internal prices and world prices. In the same time, the market oriented reforms are mixed with the other forms of government intervention. The industry network theory provides a good pillar for maintaining natural monopoly in public utilities. The conclusions which are presented in this article offer a good theory for the activity of the National Authority of Regulation in Romanian natural gas sector.

Developing power markets - Development of market place for meeting the demand - Case India, in transition from regulated to competitive structure

Energy Technology Data Exchange (ETDEWEB)

Kumar, Pranay; Sarkar, Prabhajit Kumar

2010-09-15

Power Market players of developing countries with supply deficit are exposed to a unique combination of price risk and quantity risk which is not the case with developed nations that have taken path of liberalization to open up their power markets. India has one of the largest generation capacities in the world, yet till recently the Indian Power sector was highly regulated. However, the last decade has witnessed many initiatives so as to make the sector market oriented. This paper provides opportunity for developing countries to learn from Indian experience of introducing competition in the power sector.

Analysis of multi-pollutant policies for the U.S. power sector under technology and policy uncertainty using MARKAL

International Nuclear Information System (INIS)

Hu, Ming-Che; Hobbs, Benjamin F.

2010-01-01

Investments in power generation, pollution controls, and electricity end use equipment are made in the face of uncertainty. Unanticipated events can cause regret-commitments that in retrospect were the wrong choices. We analyze how three uncertainties-electricity demand growth, natural gas prices, and power sector greenhouse gas regulations-could affect electric power sector investment decisions and costs in the U.S. over the next four decades. The effect of multi-pollutant regulations such as the Clean Air Interstate Rule (CAIR) upon these decisions and costs is also considered. We use decision trees to structure the problem, defining multiple futures for each uncertainty and then simulating how the U.S. energy market responds to them. A two-stage stochastic version of the energy-economy model MARKAL simulates the market. Relative importance of the uncertainties is assessed using two indices: expected cost of ignoring uncertainty (ECIU) and expected value of perfect information (EVPI). We also calculate the value of policy coordination (VPC), the cost saved by avoiding surprise changes in policy. An example shows how a stochastic program can be used to compute these indices. The analysis shows that the possibility of greenhouse gas regulation is the most important uncertainty by these measures.

An impact assessment of electricity and emission allowances pricing in optimised expansion planning of power sector portfolios

International Nuclear Information System (INIS)

Tolis, Athanasios I.; Rentizelas, Athanasios A.

2011-01-01

Highlights: → The impact of electricity and CO 2 allowance pricing in power sector is researched. → A stochastic programming approach without recourse is used for the optimisation. → Higher electricity prices may be proportionally beneficial for the power system. → The CO 2 allowance prices may be inversely proportionate with the expected yields. → High CO 2 allowance prices are inhibitors for conventional technology projects. -- Abstract: The present work concerns a systematic investigation of power sector portfolios through discrete scenarios of electricity and CO 2 allowance prices. The analysis is performed for different prices, from regulated to completely deregulated markets, thus representing different electricity market policies. The modelling approach is based on a stochastic programming algorithm without recourse, used for the optimisation of power sector economics under multiple uncertainties. A sequential quadratic programming routine is applied for the entire investigation period whilst the time-dependent objective function is subject to various social and production constraints, usually confronted in power sectors. The analysis indicated the optimal capacity additions that should be annually ordered from each competitive technology in order to substantially improve both the economy and the sustainability of the system. It is confirmed that higher electricity prices lead to higher financial yields of power production, irrespective of the CO 2 allowance price level. Moreover, by following the proposed licensing planning, a medium-term reduction of CO 2 emissions per MW h by 30% might be possible. Interestingly, the combination of electricity prices subsidisation with high CO 2 allowance prices may provide favourable conditions for investors willing to engage on renewable energy markets.

2007-06-01

This report addresses the Dutch power sector, identifying the major corporate players in the market, types of fuel used to generate electricity, the profits being made, and investments in both renewable and non-renewable generation capacity. For the purposes of this report, the power sector is understood to encompass production (i.e. generation) and supply of electricity. Some discussion and figures on heat and gas, which are also essential energy services, are provided, but the focus is primarily on electricity. Section 2 of the report provides an overview of the Dutch power sector, breaking the market down into production and supply. Major players, markets shares, and recent trends and developments are given for each of these activities. Sections 3 - 7 go into detail on the five major corporate players active in the Dutch power sector: ENECO, Essent, Nuon, Electrabel, and E.ON Energie. For each company, information is provided on profits and earnings, the fuel mix used to generate and supply electricity, the CO2 emissions associated with these activities, installed capacity in the Netherlands, and recent investments in renewable and non-renewable generation capacity in the Netherlands. For the Dutch companies, ENECO, Essent and Nuon, additional information on the ownership structure of the company, shareholders and dividends paid and received is given. A section on RWE (Section 8) is also included in the study because, although RWE is not currently active in generating electricity in the Netherlands, RWE Energy does currently supply electricity generated by producers in the Netherlands. In addition, RWE Power is currently planning to invest significantly in power generation capacity in the Netherlands. The final section of the report compares the companies activities in the Netherlands and draws conclusions based on the companies' respective performance

The future of Croatian power sector

Jelcic, A.; Slipac, G.; Zeljko, M.

2000-01-01

The article gives two among many possible scenarios of the power sector development in Croatia for the period between 2001 and 2030. This article observes the long period until 2030. It is understandable that the reliability of the results of the analysis for the entire period is not consistent. For the first ten years of the planning period the results can be taken with great reliability, while for the period until 2010 and onward there are only outlines of the problems rather than proposals for final solutions. The expected technological development will also contribute especially in the light of the general apprehension about consequences of pollution and the obligations overtaken at the Kyoto Conference on Environment. One of the most important issues is the safety of power sector. With the increased use of gas for electricity generation as well as in the other consumption sectors, it is essential to ensure several supply lines and enlarge storage facilities. Of course, there is also a question of diversification of sources after 2010. The study uses the coal plants for working design only, but other sources can serve the same purpose. (e.g., nuclear plants). In the next 4-5 years many presumptions of development in that period will become more transparent, so it is not necessary to bring final conclusions in this moment

Demise of the standard model for power sector reform and the emergence of hybrid power markets

International Nuclear Information System (INIS)

Gratwick, Katharine Nawaal; Eberhard, Anton

2008-01-01

Following earlier reforms in the power sectors of industrialized countries and emerging markets (e.g. Chile), developing countries were encouraged to unbundle their electricity industries and to introduce competition and private sector participation. This paper highlights the developments that led to how power sector reform came to be defined as a standard model and theoretical framework in its own right, and how the model was used prescriptively in many developing countries. However, we also show that, after more than 15 years of reform efforts, this new industry model has not fully taken root in most developing countries. Finally, we identify and characterize the emergence of new hybrid power markets, which pose fresh performance and investment challenges

This paper analyses the distribution of benefits between firms and consumers due to the price regulation of the Spanish energy sectors (electricity, oil fuels and gas) during the decade 1987-1997. To that effect, we compare the actual evolution of energy prices with alternate benchmarks in order to assess the potential existence of a pro-industry or a pro-consumer bias in the pricing policies followed by the regulator. Our results show a pro-industry-biased regulatory context, where consumers benefited very little from price control. The successive price adjustments over time allowed the companies to keep all the productivity gains and cost reductions and to increase their profitability rates relative to those achieved in the manufacturing sector.

How do countries regulate the health sector? Evidence from Tanzania and Zimbabwe.

Science.gov (United States)

Kumaranayake, L; Mujinja, P; Hongoro, C; Mpembeni, R

2000-12-01

The health sectors in many low- and middle-income countries have been characterized in recent years by extensive private sector activity. This has been complemented by increasing public-private linkages, such as the contracting-out of selected services or facilities, development of new purchasing arrangements, franchising and the introduction of vouchers. Increasingly, however, experience with the private sector has indicated a number of problems with the quality, price and distribution of private health services, and thus led to a growing focus on the role of government in regulation. This paper presents the existing network of regulations governing private activity in the health sectors of Tanzania and Zimbabwe, and their appropriateness in the context of emerging market realities. It draws on a comparative mapping exercise reviewing the complexity of the variables currently being regulated, the level of the health system at which they apply, and the specific instruments being used. Findings indicate that much of the existing regulation occurs through legislation. There is still very much a focus on the 'social' rather than 'economic' aspects of regulation within the health sector. Recent changes have attempted to address aspects of private health provision, but some very key gaps remain. In particular, current regulations in Tanzania and Zimbabwe: (1) focus on individual inputs rather than health system organizations; (2) aim to control entry and quality rather than explicitly quantity, price or distribution; and (3) fail to address the market-level problems of anti-competitive practices and lack of patient rights. This highlights the need for additional measures to promote consumer protection and address the development of new private markets such as for health insurance or laboratory and other ancillary services.

Ciarreta, Aitor; Nasirov, Shahriyar; Silva, Carlos

2016-01-01

This paper provides a comprehensive analysis of the market power problem in the Spanish power generation sector and examines how and to which extent the market has developed in terms of market power concerns after the market liberalization reforms. The methodology applied in this study includes typical ex-post structural and behavioral measures employed to estimate potential for market power, namely: concentration ratios (CR) (for the largest and the three largest suppliers), the Herfindahl–Hirschman Index (HHI), Entropy, Pivotal Supply Index, the Residual Supply Index and Residual Demand Elasticity (RDE). The results are presented for the two largest Spanish generating companies (Endesa and Iberdrola) acting in the Iberian Electricity Market (MIBEL), and in the Spanish Day-ahead electricity market. The results show evidence that these companies have behaved much more competitively in recent periods than in the beginning of the market liberalization. In addition, the paper discusses important structural and regulatory changes through market liberalization processes in the Spanish Day-ahead electricity market. - Highlights: •Competition and regulation in the Spanish electricity market. •The methodology applied in this study: ex-post structural and behavioral measures. •Key dominant companies behaved more competitively in recent periods. •Important structural and regulatory changes in the Spanish electricity market.

Implications of electric power sector restructuring on climate change mitigation in Argentina

Energy Technology Data Exchange (ETDEWEB)

Hasson, G; Bouille, D [Instituto de Economia Energetica, (Argentina); Redlinger, R [UNEP, (Denmark)

2000-05-01

The Argentine electricity industry has undergone fundamental reforms since 1992, involving large-scale privatisation, and competition in generation and wholesale power markets. In terms of climate change mitigation, these reforms have had the beneficial effect of encouraging improved generation efficiency among thermal power plants and improved end-use consumption efficiency among large industrial firms. However, the reforms have also had the negative effect (from a climate change perspective) of encouraging an ever-increasing use of natural gas combustion for electricity generation, greatly diminishing the role of hydroelectric power which had previously played an important role in the Agentine electricity sector. This report examines the current structure and regulations of the Argentine electricity system and analyses the forces at work which are influencing current technology choices, both in terms of power generation and end-use consumption. The report goes on to examine international experiences in promoting renewable energy and energy efficiency technologies; and finally, the report considers the applicability of these various policy mechanisms within the Agentine context.

Effect of nuclear power on CO₂ emission from power plant sector in Iran.

Science.gov (United States)

Kargari, Nargess; Mastouri, Reza

2011-01-01

It is predicted that demand for electricity in Islamic Republic of Iran will continue to increase dramatically in the future due to the rapid pace of economic development leading to construction of new power plants. At the present time, most of electricity is generated by burning fossil fuels which result in emission of great deal of pollutants and greenhouse gases (GHG) such as SO₂, NOx, and CO₂. The power industry is the largest contributor to these emissions. Due to minimal emission of GHG by renewable and nuclear power plants, they are most suitable replacements for the fossil-fueled power plants. However, the nuclear power plants are more suitable than renewable power plants in providing baseload electricity. The Bushehr Nuclear Power Plant, the only nuclear power plant of Iran, is expected to start operation in 2010. This paper attempts to interpret the role of Bushehr nuclear power plant (BNPP) in CO₂ emission trend of power plant sector in Iran. In order to calculate CO₂ emissions from power plants, National CO₂ coefficients have been used. The National CO₂ emission coefficients are according to different fuels (natural gas, fuels gas, fuel oil). By operating Bushehr Nuclear Power Plant in 2010, nominal capacity of electricity generation in Iran will increase by about 1,000 MW, which increases the electricity generation by almost 7,000 MWh/year (it is calculated according to availability factor and nominal capacity of BNPP). Bushehr Nuclear Power Plant will decrease the CO₂ emission in Iran power sector, by about 3% in 2010.

Power sector reform in Maharashtra, India

International Nuclear Information System (INIS)

Totare, Ninad P.; Pandit, Shubha

2010-01-01

In early 1990 the power sector in India required an initial set of reforms due to the scarcity of financial resources and its deteriorating technical and commercial efficiency. The Indian power sector is now going through a second stage of reforms in which restructuring of electric supply utilities has taken place. The Maharashtra State Electricity Board (MSEB) initiated reforms in 2005 by dividing the state electricity board into four separate companies. In this paper, the situations that led to the reform of the MSEB and the scope of the work required for an action plan initiated by the state electricity distribution company in the context of the proposed Key Performance Index are discussed. The post-reform status of the distribution company is analyzed with selected key parameters. The study also analyzes the electricity supply model implemented and the effect of a multi-year tariff plan as one of the key milestones of the tariff structure. The various new projects implemented by the distribution company to improve consumer services and the reform experiences of the other states are discussed, along with the future scope of the present reform process.

Poland belongs to the European Union countries with the highest mercury emissions. This is mainly related to coal combustion. This paper presents estimates of mercury emissions from power sector in Poland. In this work, the bottom-up approach was applied and over 160 emission point sources were analysed. For each, the characteristics of the whole technological chain starting from fuel quality, boiler type as well as emission controls were taken into account. Our results show that emissions of mercury from brown coal power plants in 2005 were nearly four times greater than those of hard coal power plants. These estimates differ significantly from national statistics and some possible reasons are discussed. For the first time total mercury emissions from the Polish power sector were differentiated into its main atmospheric forms: gaseous elemental (GEM), reactive gaseous (RGM) and particulate-bound mercury. Information on emission source location and the likely vertical distribution of mercury emissions, which can be used in modelling of atmospheric dispersion of mercury is also provided.

The EU commission is planning to launch an emission trading market for greenhouse gases within near future. This to meet its obligations under the United Nations Framework Convention on Climate Change and the Kyoto Protocol. After a theoretical discussion on market power in such a market, wc turn to the empirical evidence which suggests that a reasonable number of sources of C02 emissions in the power sector exists for bollers larger than 25MW. Overall, together with the contestable single market for electricity, the risk of significant strategies behaviour seems negligible. Thus, the electric utility sector seems a suitable testing ground for an EU-scheme of emissions trading. In the longer run, it will be important to broaden the scope of the trading scheme as the inclusion of other sectors will further limit the risk of market power. (au)

The level of investment required by the Russian power sector by 2020 are expected to be in the range of USD 500-550 billion. It is of vital importance that Russia outlines an appropriate regulatory regime for its energy market that attracts foreign investors and combats corruption. The most important challenges determining the long term development of the country's power sector are skills development, regulatory effectiveness, corporate governance, and assurance regarding private investments.

In India population and economic growth is expected to create serious power shortages triggering the need for new power generation capacity. The situation is worsened on account of stagnant conditions prevailing in the country during the past few years. The opening of economy to the global market is expected to usher in an increased economic growth bringing in its wake greater demand for power. It will, thus, be seen that to cater these requirements the power sector industry in the country will have to grow at a much faster rate in the near future. However, to have a correct perspective of the emerging scenario, it might be worthwhile to have a look at the past patterns of development. (author). 9 refs., 5 tabs

Carbon emission scenarios of China's power sector: Impact of controlling measures and carbon pricing mechanism

Directory of Open Access Journals (Sweden)

Qiang Liu

2018-03-01

Full Text Available The study constructs a low-carbon path analysis model of China's power sector based on TIMES model and presents a comparative analysis of carbon emissions under Reference, Low-Carbon and Enhanced Low-Carbon scenarios, and the main difference of the three scenarios is manifested by policy selection and policy strength. The conclusions are drawn as follows: (1 The peak of carbon emission in China's power sector will range from 4.0 GtCO2 to 4.8 GtCO2, which implies an increment of 0.5–1.3 billion or 14%–35% from the 2015 levels. (2 Introducing carbon price is an effective way to inhibit coal power and promote non-fossil fuels and Carbon Capture, Utilization and Storage applications (CCUS. The carbon emission reduction effects will gradually increase with carbon price. When the carbon price attains to CN¥150 t−1CO2, the CO2 emission can decrease by 36% than that without carbon price. (3 CCUS is one of important contributing factor to reduce CO2 emission in power sector. Generally speaking, the development of non-fossil fuels and energy efficiency improvement are two main drivers for carbon mitigation, but once the carbon price reaches up to CN¥106 t−1CO2, the CCUS will be required to equip with thermal power units and its contribution on carbon emission reduction will remarkably increase. When carbon price increases to CN¥150 t−1CO2 in 2050, the application of CCUS will account for 44% of total emission reduction. (4 In the scenario with carbon price of CN¥150 t−1CO2, power sector would be decarbonized significantly, and the CO2 intensity will be 0.22 kgCO2 (kW h−1, but power sector is far from the goal that achieving net zero emission. In order to realize the long-term low greenhouse gas emission development goal that proposed by the Paris Agreement, more efforts are needed to be put to further reduce the carbon emission reduction of power sector. Based on the above scenario analysis, the study proposes four recommendations

The Europeanization of regulation of the energy sector

Lavrijsen, S.A.C.M.; Nauta, T.

2010-01-01

The main question of this article is how the ongoing Europeanization of regulation relates to the restrictive manner in which the Dutch legislator interprets the principle of legality with respect to the qualification of the independent regulating authorities. To answer this question, research focuses first of all on which demands are imposed by European law on the constitutional position and qualification of the national regulating authorities that implement the energy directives. Anticipating the consequences of the third generation of energy directives for the position of the national authorities, attention is subsequently paid to the question whether any tension exists between European requirements for the regulation of the energy sector and the manner in which the national legislator interprets the principle of legality.

Financing the UK power sector: Is the money available?

International Nuclear Information System (INIS)

Blyth, William; McCarthy, Rory; Gross, Robert

2015-01-01

The UK power generation sector faces a major new round of investment: the coincidence of asset retiring and ambitious goals for decarbonisation is not unique, but is particularly acute in the UK. The UK government has put in place a raft of new policies that seek to promote new, low carbon investment and ensure security of supply. The traditional channel for financing the sector has been through large utility companies, but this now looks challenging for various reasons. The UK therefore offers an interesting case study on several counts; the scale of the challenge, effectiveness of new policies, and the availability of alternative finance. We find that the link between the finance sector and the electricity sector is not ‘broken’, but the flow of money to the sector is threatened by the current weakness of the utilities’ business model. This paper compares estimates of the scale of investment required in the UK with historical investment rates. It summarises contemporary finance industry views of conditions and trends, and potential policy interventions that might be needed to bridge the investment gap. The potential for channelling institutional investor funds directly into energy assets is reviewed. - Highlights: • Power investment need to scale up compared to historical trends, but is achievable. • Traditionally, low-cost finance has been through bonds and shares of large utilities. • Utilities are suffering high debt, reduced demand, and suppressed prices. • Policy interventions to scale-up investment are reviewed.

Government regulation as an impetus for innovation: Evidence from energy performance regulation in the Dutch residential building sector

Beerepoot, Milou; Beerepoot, Niels

2007-01-01

The recent implementation of energy performance policy as a way to tackle energy consumption in the building sector in Europe draws attention to the effect it has on the development and diffusion of energy-saving innovations. According to innovation system literature, government regulation through norms and standards is one of the factors stimulating innovation. This paper concentrates on the role of stricter government regulation as an incentive to innovation in the Dutch residential building sector. Innovation in this sector is predominantly a process of applying incremental modifications to comply with new and stricter government regulations and standards. Energy performance policy in its current shape will therefore not contribute to the diffusion of really new innovation in energy techniques for residential buildings in the Netherlands. If diffusion of really new innovation is an explicit aim of energy performance policy then the European wide introduction of this scheme needs reconsideration

Restructuring of the power sector in Romania - options and perspectives

Energy Technology Data Exchange (ETDEWEB)

Leca, A. [University Politechnica, Bucharest (Romania)

1999-07-01

Discusses the Romanian energy sector covering the situation under the Communist government and attempts at restructuring since the fall of Communism. Following the fall of Communism 1989, the power sector remained in State ownership and suffered problems such as a lack of a national energy strategy, a weak institutional framework, and the persistence of monopolistic relationships between suppliers and consumers. In 1997 a new government began a programme of energy reform aiming to, for example, improve energy efficiency, set up an institutional framework, reduce environmental impacts and re-evaluate generation capacities of existing plants and those under construction but political problems have slowed the process down. The paper suggests that privatisation is becoming the only solution to problems in the power sector caused by the deterioration of the economic and social situation in Romania. 8 figs., 1 tab.

Panorama 2015 - Gas and Coal Competition in the EU Power Sector

International Nuclear Information System (INIS)

Cornot-Gandolphe, Sylvie

2014-12-01

Never have the fossil-fueled thermal European power sector, and natural gas in this sector, seen such a crisis. EON's recent announcement of its future withdrawal from fossil-fueled thermal power generation illustrates the difficulties faced by producers in Germany. But the whole European power sector is in deep crisis, and natural gas is its first victim. Faced with a flat electricity demand in Europe, the rapid development of renewable energies, and competition from coal, natural gas is losing market share and its consumption is in decline. In 2013, total gas consumption in the European Union (EU) fell for the third year running. Projections for 2014 are no better, consumption is forecast to decline by approximately 10%, greatly affected by the mild winter of 2013/2014 compared with the previous one which was particularly cold over a long period. The milder temperatures impact the need for heating, therefore consumption in the residential/services sectors and also the demand for electricity. The International Energy Agency (IEA) is now predicting that European consumption will not get back to its 2010 level until 2032. (author)

The past, present, and future of the U.S. electric power sector: Examining regulatory changes using multivariate time series approaches

Science.gov (United States)

Binder, Kyle Edwin

The U.S. energy sector has undergone continuous change in the regulatory, technological, and market environments. These developments show no signs of slowing. Accordingly, it is imperative that energy market regulators and participants develop a strong comprehension of market dynamics and the potential implications of their actions. This dissertation contributes to a better understanding of the past, present, and future of U.S. energy market dynamics and interactions with policy. Advancements in multivariate time series analysis are employed in three related studies of the electric power sector. Overall, results suggest that regulatory changes have had and will continue to have important implications for the electric power sector. The sector, however, has exhibited adaptability to past regulatory changes and is projected to remain resilient in the future. Tests for constancy of the long run parameters in a vector error correction model are applied to determine whether relationships among coal inventories in the electric power sector, input prices, output prices, and opportunity costs have remained constant over the past 38 years. Two periods of instability are found, the first following railroad deregulation in the U.S. and the second corresponding to a number of major regulatory changes in the electric power and natural gas sectors. Relationships among Renewable Energy Credit prices, electricity prices, and natural gas prices are estimated using a vector error correction model. Results suggest that Renewable Energy Credit prices do not completely behave as previously theorized in the literature. Potential reasons for the divergence between theory and empirical evidence are the relative immaturity of current markets and continuous institutional intervention. Potential impacts of future CO2 emissions reductions under the Clean Power Plan on economic and energy sector activity are estimated. Conditional forecasts based on an outlined path for CO2 emissions are

Social cost of carbon pricing of power sector CO2: accounting for leakage and other social implications from subnational policies

Science.gov (United States)

Bistline, John E.; Rose, Steven K.

2018-01-01

In environments where climate policy has partial coverage or unequal participation, carbon dioxide (CO2) emissions or economic activity may shift to locations and sectors where emissions are unregulated. This is referred to as leakage. Leakage can offset or augment emissions reductions associated with a policy, which has important environmental and economic implications. Although leakage has been studied at national levels, analysis of leakage for subnational policies is limited. This is despite greater market integration and many existing state and regional environmental regulations in the US. This study explores leakage potential, net emissions changes, and other social implications in the US energy system with regionally differentiated pricing of power sector CO2 emissions. We undertake an economic analysis using EPRI’s US-REGEN model, where power sector CO2 emissions are priced in individual US regions with a range of social cost of carbon (SCC) values. SCC estimates are being considered by policy-makers for valuing potential societal damages from CO2 emissions. In this study, we evaluate the emissions implications within the SCC pricing region, within the power sector outside the SCC region, and outside the power sector (i.e. in the rest of the energy system). Results indicate that CO2 leakage is possible within and outside the electric sector, ranging from negative 70% to over 80% in our scenarios, with primarily positive leakage outcomes. Typically ignored in policy analysis, leakage would affect CO2 reduction benefits. We also observe other potential societal effects within and across regions, such as higher electricity prices, changes in power sector investments, and overall consumption losses. Efforts to reduce leakage, such as constraining power imports into the SCC pricing region likely reduce leakage, but could also result in lower net emissions reductions, as well as larger price increases. Thus, it is important to look beyond leakage and consider a

Problems of standardizing and technical regulation in the electric power industry

Science.gov (United States)

Grabchak, E. P.

2016-12-01

A mandatory condition to ensure normal operation of a power system and efficiency in the sector is standardization and legal regulation of technological activities of electric power engineering entities and consumers. Compared to the times of USSR, the present-time technical guidance documents are not mandatory to follow in most cases, being of an advisory nature due to the lack of new ones. During the last five years, the industry has been showing a deterioration of the situation in terms of ensuring reliability and engineering controllability as a result of the dominant impact of short-term market stimuli and the differences in basic technological policies. In absence of clear requirements regarding the engineering aspects of such activities, production operation does not contribute to the preserving of technical integrity of the Russian power system, which leads to the loss of performance capability and controllability and causes disturbances in the power supply to consumers. The result of this problem is a high rate of accident incidence. The dynamics of accidents by the type of equipment is given, indicating a persisting trend of growth in the number of accidents, which are of a systematic nature. Several problematic aspects of engineering activities of electric power engineering entities, requiring standardization and legal regulation are pointed out: in the domestic power system, a large number of power electrotechnical and generating equipment operate along with systems of regulation, which do not comply with the principles and technical rules representing a framework where the Energy System of Russia is built and functioning

The U.S. government, along with other governments, private corporations and organizations, invests significantly in research, development, demonstration and deployment (RDD&D) activities in clean energy technologies, in part to achieve the goal of a clean, secure, and reliable energy system. While specific outcomes and breakthroughs resulting from RDD&D investment are unpredictable, it can be instructive to explore the potential impacts of clean energy RDD&D activities in the power sector and to place those impacts in the context of current and anticipated market trends. This analysis builds on and leverages analysis by the U.S. Department of Energy (DOE) titled “Energy CO₂ Emissions Impacts of Clean Energy Technology Innovation and Policy” (DOE 2017). Similar to DOE (2017), we explore how additional improvements in cost and performance of clean energy technologies could impact the future U.S. energy system; however, unlike the economy-wide modeling used in DOE (2017) our analysis is focused solely on the electricity sector and applies a different and more highly spatially-resolved electric sector model. More specifically, we apply a scenario analysis approach to explore how assumed further advancements in clean electricity technologies would impact power sector generation mix, electricity system costs, and power sector carbon dioxide (CO₂) emissions.

The superconducting magnets and associated cryogenic components in A-sector represent the initial phase of installation of the Fermilab superconducting accelerator, designed to accelerate proton beams to energies of 1 TeV. Installation of the magnets, comprising one-eighth of the ring, was completed in December, 1981. Cooldown and power tests took place in the first half of 1982, concurrent with main ring use for 400 GeV high energy physics. The tests described in this paper involved 151 cryogenic components in the tunnel: 94 dipoles, 24 quadrupoles, 25 spool pieces, 3 feed cans, 4 turn-around boxes and 1 bypass. Refrigeration was supplied by three satellite refrigerators, the Central Helium Liquefier, and two compressor buildings. The magnets were powered by a single power supply

Carbon mitigation in the electric power sector under cap-and-trade and renewables policies

International Nuclear Information System (INIS)

Delarue, Erik; Van den Bergh, Kenneth

2016-01-01

In Europe, CO_2 emissions from the electric power sector and energy intensive industries are capped under a cap-and-trade system (i.e., the EU ETS). When other indirect measures are taken to impact emissions in a specific sector under the cap (such as a push for renewables in the electric power sector), this has implications on the overall allowance price, and on CO_2 emissions both from this specific sector and the other sectors under the cap. The central contribution of this paper is the derivation of impact curves, which describe these interactions, i.e., the impact on allowance price and the shift of emissions across sectors. From a set of detailed simulations of the electric power system operation, a so-called “emission plane” is obtained, from which impact curves can be derived. Focus is on interactions between CO_2 abatement through fuel switching and measures affecting the residual electricity demand (such as deployment of renewables) in the electric power sector, as well as on interactions with other sectors, both in a short-term framework. A case study for Central-Western Europe is presented. The analysis reveals a substantial impact of renewables on CO_2 emissions, and hence on emissions shifts across sectors and/or on the CO_2 price. - Highlights: •CO_2 cap-and-trade interacts with policies targeting one specific sector under cap. •Interaction creates emission displacement and/or impacts CO_2 price. •The central contribution is the derivation of impact curves from the emission plane. •The method is applied to a case study of Central-Western Europe. •The analysis reveals a large impact of renewables on CO_2 displacement and/or price.

Evaluation of Integrated Air Pollution and Climate Change Policies: Case Study in the Thermal Power Sector in Chongqing City, China

Directory of Open Access Journals (Sweden)

2017-09-01

Full Text Available The cost of environmental degradation has already had a dramatic impact on the Chinese economy. In order to curb these trends, the government of China has introduced stricter regulations. With this in mind, it is important to quantify the potential co-benefits of introducing air pollution and climate change mitigation policies. This study proposes relevant scenarios ranging from the current trends (baseline to the introduction of different policies in the thermal power sector, including different carbon tax rates, technology innovation promotion, and technology cost reduction methods. We aim to comparatively evaluate the impact of the proposed policies within the thermal sector and within the entire socio-economic system. To this end, we used a dynamic input–output (I-O model, into which high-efficiency technologies were incorporated as new thermal power industries in order to estimate policy impact during the time period 2010–2025. The results of this study demonstrated that the introduction of one or more of the following policies: carbon taxes, subsidies, technology innovation, and technology cost reduction, has no notable impact on the environment or the economy without the implementation of environment regulations. In contrast, the strong support of a government subsidy coupled with strict environmental regulations will promote technological innovation, for example through the natural gas combined cycle (NGCC and the integrated coal gasification combined cycle (IGCC. Our study also showed that the reduction of air pollution and greenhouse gas emissions as well as energy consumption would curb economic development to a certain extent. Taking this into consideration, innovation must also be promoted in other economic sectors. This research provides a strong reference for policy-makers to identify effective polices under different types of environmental regulations.

Asymmetric regulation measures in the European gas sector

International Nuclear Information System (INIS)

Clastres, C.

2003-01-01

Like most of the privatized utilities, the gas market needs to be regulated in order for the positive benefits of competition to fully develop. In addition to the issues of eligibility and access, the regulators have had to deal with several other obstacles, and among other things have raised questions concerning the supply of gas. Asymmetric regulation (release gas and market share reduction measures) is one of the possible responses, making it possible to facilitate access to both resources and consumers. The British regulator was the first to introduce this type of regulation during the 1990's. More recently, Spain and Italy have also adopted it. Although we can find a number of similarities in the causes justifying the use of such regulation, the results obtained vary from one country to another. It appears that they are dependent upon a number of variables including: the existence of national production, the structure of the gas market and finally the level of penetration and growth of gas in various business sectors.

The most important issues in the European energy sector today are how to increase competitiveness on the energy markets, reduce both CO2 emissions and dependence on imported fuels. These issues are also important aspects of Swedish energy policy. In Sweden, the district heating (DH) sector has commonly been used to achieve Swedish energy policy goals. However, the ongoing integration and deregulation of the energy markets in Europe now means that the Swedish DH sector can also play an important role in achieving international targets. This thesis investigates the extent to which the Swedish DH sector can contribute to compliance with current energy policy targets, both international and Swedish. The study consisted of simulations of the Swedish DH sector response to various policy instruments in a model that takes the local features of virtually all Swedish DH systems into account. The findings show, for example, that there is great potential for combined heat and power (CHP) generation in the Swedish DH sector. By exporting this CHP electricity to other European countries with less effective and fossil dependent power generation plants, the CO2 emissions from the European energy sector could be substantially reduced. This would also result in increased security of supply and competitiveness in the EU, since fuel use would be more effective. In Sweden, increased CHP generation would also be a way of maintaining an effective national security of supply of power

This research presents a comparative assessment of the regulation models of the nuclear sector in Argentina - under the responsibility of the Autoridad Regulatoria Nuclear (ARN), and Brazil - under the responsibility of Comissao Nacional de Energia Nuclear (CNEN), trying to identify which model is more adequate aiming the safe use of nuclear energy. Due to the methodology adopted, the theoretical framework resulted in criteria of analysis that corresponds to the characteristics of the Brazilian regulatory agencies created for other economic sector during the State reform staring in the middle of the nineties. Later, these criteria of analysis were used as comparison patterns between the regulation models of the nuclear sectors of Argentina and Brazil. The comparative assessment showed that the regulatory structure of the nuclear sector in Argentina seems to be more adequate, concerning the safe use of nuclear energy, than the model adopted in Brazil by CNEN, because its incorporates the criteria of functional, institutional and financial independence, competence definitions, technical excellence and transparency, indispensable to the development of its functions with autonomy, ethics, exemption and agility.

Liberalising European electricity markets: opportunities and risks for a sustainable power sector

International Nuclear Information System (INIS)

Ringel, M.

2003-01-01

The process of liberalising European electricity markets, encompassing a wide range of restructuring activities, has mainly been spurred by the attempt to increase the economic efficiency of the whole sector. This process might be used to trigger a development towards a sustainable power sector by increasing the use of renewable energy sources and enhancing energy efficiency on the supply and demand side. However, by taking a closer look at the current trends of the European electricity markets, it becomes obvious that the liberalisation not only implies opportunities but also risks for the creation of a sustainable power sector. Many of these risks are due to market distortions and imperfections caused by the delay in creating a fully functional single European market. Thus, in the short-term, the market liberalisation tends to constitute more risks than opportunities without government actions to prevent these risks. In the long run, though, the efficiency gains of the sector and the appearance of new market factors are likely to bring forth the opportunities of liberalisation and actively foster a transformation towards a sustainable electricity sector.

Impact of the economic recession on the European power sector's CO2 emissions

International Nuclear Information System (INIS)

Declercq, Bruno; Delarue, Erik; D'haeseleer, William

2011-01-01

This paper investigates the impact of the economic recession on CO 2 emissions in the European power sector, during the years 2008 and 2009. Three main determinants of the power sector's emissions are identified: the demand for electricity, the CO 2 price, and fuel prices. A counterfactual scenario has been set up for each of these, i.e., what these parameters would have been if not affected by the recession. A simulation model of the European power sector is then employed, comparing a historical reference simulation (taking the parameters as actually occurred) with the counterfactual scenarios. The lower electricity demand (due to the recession) is shown to have by far the largest impact, accounting for an emission reduction of about 175 Mton. The lower CO 2 price (due to the recession) resulted in an increase in emissions by about 30 Mton. The impact of fuel prices is more difficult to retrieve; an indicative reduction of about 17 Mton is obtained, mainly as a consequence of the low gas prices in 2009. The simulated combined impact of the parameters results in an emission reduction of about 150 Mton in the European power sector over the years 2008 and 2009 as a consequence of the recession. - Research highlights: → CO 2 emissions are simulated for the European power sector. → Emissions reduced drastically because of the economic recession in 2008 and 2009. → Lower electricity demand had highest impact and accounts for reduction of about 175 Mton. → Impact of different CO 2 and fuel prices on emissions is more limited.

Ahmad, Muhammad; Wang, Zhixin; Wang, Jinjian; Baloach, Mazhar H.; Longxin, Bao; Hua, Qing

2018-04-01

Recently a paradigm shift in the power sector is observed, i.e., countries across the globe have deviated their attention to distributed generation rather than conventional centralized bulk generation. Owing to the above narrative, distributed energy resources e.g., wind and PV have gained the adequate attention of governments and researchers courtesy to their eco-friendly nature. On the contrary, the increased infiltration of distributed generation to the power system has introduced many technical and economical glitches such as long-distance transmission, transmission lines efficiency, control capability and cost etc. To mitigate these complications, the utility of high voltage direct current (HVDC) transmission has emerged as a possible solution. In this context, this paper includes a brief discussion on the fundamentals HVDC and its significance in Pakistani power sector. Furthermore, the potential of distributed energy resources for Pakistan is also the subject matter of this paper, so that significance of HVDC transmission can effectively be deliberated.

Power-Controlled CDMA Cell Sectorization with Multiuser Detection: A Comprehensive Analysis on Uplink and Downlink

2007-12-01

Full Text Available We consider the joint optimization problem of cell sectorization, transmit power control and multiuser detection for a CDMA cell. Given the number of sectors and user locations, the cell is appropriately sectorized such that the total transmit power, as well as the receiver filters, is optimized. We formulate the corresponding joint optimization problems for both the uplink and the downlink and observe that in general, the resulting optimum transmit and receive beamwidth values for the directional antennas at the base station are different. We present the optimum solution under a general setting with arbitrary signature sets, multipath channels, realistic directional antenna responses and identify its complexity. We propose a low-complexity sectorization algorithm that performs near optimum and compare its performance with that of optimum solution. The results suggest that by intelligently combining adaptive cell sectorization, power control, and linear multiuser detection, we are able to increase the user capacity of the cell. Numerical results also indicate robustness of optimum sectorization against Gaussian channel estimation error.

Demand-side management (DSM) in the context of China's on-going power sector reform

International Nuclear Information System (INIS)

Zhang, Sufang; Jiao, Yiqian; Chen, Wenjun

2017-01-01

As an approach to manage power demand-side resources, DSM plays an important role in electric power system. Though DSM was introduced into China in the early 1990s, its benefits have been underutilized. Using literature study, interview methods and three data sources, this paper examines the likely impacts of China's on-going power sector reform on its DSM. It finds that the major constraints to DSM in China are the insufficient and improper market-based DSM mechanism, grid companies’ low motivations for DSM due to their traditional business model, the underdeveloped energy service industry, and electricity end-users’ low motivation for DSM. China's on-going power sector reform will change power transmission and distribution pricing and grid companies’ business model and introduce competition into retail-side. Drawing on these findings, it is concluded that the likely impacts of the new reform on DSM are: governments may attach more importance to DSM; grid companies may have more motivations for DSM investment; electricity end-users’ motivations for DSM may be both enhanced and dampened; electricity retailers’ motivations for DSM may be dampened; demand response application may be enhanced, and more DSM business models may be developed. Finally, policy implications are provided. - Highlights: • Mechanism of and constraints to DSM in China are examined. • China’s on-going power sector reform is overviewed. • DSM is likely to be enhanced under China's on-going power sector reform. • Policy implications are provided.

Impacts on investments, and transmission/distribution loss through power sector reforms

International Nuclear Information System (INIS)

Nagayama, Hiroaki

2010-01-01

This study analyses original panel data from 86 countries between 1985 and 2006. Econometric methods were used to identify the effects of different policy devices of power sector reforms on performance indicators (installed capacity per capita, transmission and distribution loss) in the countries analyzed. The research findings suggest that reform variables such as the entry of independent power producers (IPPs), unbundling of generation and transmission, establishment of regulatory agencies, and the introduction of a wholesale spot market are the driving forces of increasing generation capacity, as well as reducing transmission and distribution loss in the respective regions. In this study, we can assume that, firstly, different electric industry's reform policies/measures have different impacts on geographically and economically diverse countries. Secondly, a country's state of economic development has a different impact on policy effects of reforms. Thirdly, coexistent with independent regulatory agencies, reform policy becomes more powerful in realizing sector performances.

2015-04-01

Full Text Available Mercury (Hg is a highly toxic pollutant with a long range transport in the atmosphere resulting in both local and global concerns. Understanding of emissions is required to support an effective control strategy. In this study, atmospheric Hg emissions from power sector in Thailand in 2010 were investigated by using the bottom-up approach to improve the accuracy of the estimate by up to 50% in comparison to those provided in global inventories. The activity data of each individual source were collected and emissions factors were assessed based on local sources, well reflecting the emissions behavior of various emitters in Thailand. The atmospheric Hg emissions from power sector in 2010 amounted to 844.5 kg, in which emissions from coal and lignite power plants constituted up to 92.3% and biomass power plants constituted up to 7.4%. Spatial and temporal distribution analysis indicated high emissions in the Central and Northern regions, and from February to July. Annual trends in emissions from 2010 to 2030 were estimated and discussed.

Economic issues relating to power sector

International Nuclear Information System (INIS)

Nair, S.K.N.; Mohan, Rakesh

1998-01-01

Financial distress alongside high rates of growth, stagnant organizations coexistent with upgraded technologies, richly endowed regions marked by low levels of electricity consumption and the long wait for private power in face of mounting shortfalls are among the contradictions marking the power sector. Decades of public financing support could shore up the rates of growth but forms of past intervention failed to address critical institutional and regulatory issues. Key areas that need intervention have now been identified, although several are yet to be tackled. This paper discusses the more important of the problem areas holding up significant economic gains that could be realized through cost reductions, the needed levels of investments, operation of market forces and targeting of resources to promote equitable growth. The slow pace of progress is a matter for concern. Effectiveness of many of the policy initiatives of government is also dependent on providing well thought out policy supports. (author)

Challenge The lack of transparent, accessible, and centralized power sector data inhibits the ability to research the impact of the global power sector. information gaps for citizens, analysts, and decision makers worldwide create barriers to sustainable development efforts. The need for transparent, accessible, and centralized information is especially important to enhance the commitments outlined in the recently adopted Paris Agreement and Sustainable Development Goals. Offer Power Watch will address this challenge by creating a comprehensive, open-source platform on the world's power systems. The platform hosts data on 85% of global installed electrical capacity and for each power plant will include data points on installed capacity, fuel type, annual generation, commissioning year, with more characteristics like emissions, particulate matter, annual water demand and more added over time. Most of the data is reported from national level sources, but annual generation and other operational characteristiscs are estimated via Machine Learning modeling and remotely sensed data when not officially reported. In addition, Power Watch plans to provide a suite of tools that address specific decision maker needs, such as water risk assessments and air pollution modeling. Impact Through open data, the platform and its tools will allow reserachers to do more analysis of power sector impacts and perform energy modeling. It will help catalyze accountability for policy makers, businesses, and investors and will inform and drive the transition to a clean energy future while reaching development targets.

Contesting authority: China and the new landscape of power sector governance in the developing world

Science.gov (United States)

Hannam, Phillip Matthew

Two co-constructed trends threaten to complicate global efforts to manage climate change. Electric power in developing countries is becoming more coal-intensive, while the international institutions capable of assisting lower-carbon growth paths are having their authority challenged by an emergent set of institutions under China's leadership. In the last decade Chinese firms and state banks have become central players in power sector development across the developing world; China has been involved in over sixty percent of Africa's hydropower capacity and is the single largest exporter of coal power plants globally. Statistical and qualitative evidence suggests that China's growing role in these power markets has contributed to re-prioritization of the power sector in U.S. bilateral development assistance, complicated negotiation and implementation of coal power finance rules among OECD export credit agencies, and influenced where the World Bank chooses to build hydropower projects. The thesis establishes a framework for understanding responses to discord in development governance by drawing inductively on these contemporary cases. Competition between established and emerging actors increases with two variables: 1) conflicting ideological, commercial and diplomatic goals (difference in interests); and 2) the degree to which the emerging actor challenges rules and norms upheld by the established actor (contested authority). Competitive policy adjustment - one actor seeking to undermine or diminish the other's pursuit of its objectives - has been historically commonplace when an emerging actor challenged an established actor in the regime for development assistance. China's growing authority in global power sector assistance has prompted competitive policy adjustment among established donors while also enabling recipient countries to leverage donors and better direct their own development pathways. The thesis shows that although contested authority increases

Reorganization of the power distribution sector in India

International Nuclear Information System (INIS)

Dossani, Rafiq

2004-01-01

This paper presents the central issues for electricity-sector reform in India, as they grew out of the reform process that began in 1991, and within the context of the sector's organization, regulatory structure, and other institutional characteristics. The paper argues that India's current reform policies will not be sufficient to achieve reliable, efficient power because distribution reform has not been done. Undertaking distribution reform is a difficult path to tread because of the absence of global consensus on best practices and conflicting forces, both economic and political. The paper analyzes alternative institutional structures for reform in the distribution sector. The findings include that the objectives of coverage and efficiency may conflict, that economically efficient reorganization may be politically unachievable and that the small, municipally owned firm may be the best compromise. Since many Indian states are economically and politically diverse from each other, and include both large served and unserved areas, there is scope to vary the organizational structure depending on the state's situation. This paper provides a means to do so. The agenda for policymakers is to identify the situation in their respective states and choose a reorganization path that is the best compromise

This document comprises two reports. A first one, published and updated three times a year, and a second one which is a yearly publication. The first one, based on an analysis of market perspectives and of actor strategies, proposes a synthesis on the consequences of the evolution of the economic environment, on major trends noticed for the electric power sector, and on predictable evolutions. It proposes the most recent data regarding the activities of about 200 firms belonging to the power sector (notably in terms of turnover and of electric power consumption). It highlights recent events for companies of the sector: takeovers, investments, restructuring, introduction of new products, and so on. It proposes a sector-based dashboard which contains all the critical figures useful to analyse the sector situation (activity determining factors, key figures for the sector and its environment). The annual report proposes a presentation of the sector and of the determining factors of its activity, an analysis of the activity evolution (trends, indicators like turnover, electric power consumption and production, prices and regulated tariffs, power imports and exports), a presentation of financial performance of electricity producers, a description of the sector economic structure (evolution of the economic tissue, analysis of structural characteristics), and a presentation of actors and of the competitive landscape (ranking and positioning of electric power providers and producers, market shares, identity sheets of the main actors, highlights, and ranking of the main companies in terms of turnover and of financial performance)

Full Text Available The aim of the paper is to quantify an impact of the new Basel regulation rules which are known as Basel III on the Slovak banking sector. We present methodology provided by the Bank for international settlement in its monitoring workbook and as to database the set of central bank statements and reports provided upon request have been used. Based on our calculations we discovered three main impacts of the Basel III on the Slovak banking sector: i the volume and quality of the capital meet requirements of the new Basel regulation already. There are no hybrid instruments in Tier 1 Capital. Movements in volumes of expected risk-weighted assets in the Slovak banking sector won´t be relevant particularly due to absence of toxic assets associated with financial markets; ii calculated indicator of leverage is more than two times higher as the requested one; iii the liquidity coverage ratio and the net stable funding ratio are even today in the Slovak banking sector highly above standards and they do not require any transitional period. The direction of the development of the world banking is returning to the classical trading model and the parameters are set for this. The Slovak banking sector did not manage to leave this classical model and this will help it now and also in the future.

Emerging Changes in the Worldwide Power Sector: The Assets of Thermal Power

Energy Technology Data Exchange (ETDEWEB)

Moliere, Michel; Girardot, Amelie; Jones, Robert M.

2007-07-01

In forthcoming decades we will see major changes in the landscape of the worldwide power sector as CO2 management and incipient hydrocarbon scarcity exert their increasing influence. The power generation community must be prepared to satisfy a particularly complex and challenging set of requirements. These issues include curbing CO2 emissions, coping with surging primary energy prices, and compliance with regional and local emissions requirements such as SOx and NOx-while maintaining maximum efficiency. In this context, as confirmed by International Energy Agency forecasts, thermal power will maintain a prominent position in overall power generation since it enables the large capacity additions required in emerging countries. Thanks to their reliable assets (such as energy efficiency and environment) gas turbine-based power systems, including Gas Turbine Combined Cycles (GTCC) and Combined Heat & Power (CHP), will continue to be major contributors to worldwide power generation. However, evolving changes in the spectrum of fuels will create an additional challenge for power generation equipment manufacturers-requiring innovative technologies in fuel processing, combustion, and emission controls to address these needs. This paper reviews the factors underlining the changing power generation environment worldwide, including the increasing scarcity of conventional fuels and the growing interest in biofuels and hydrogen. Insights will be offered into various technologies needed to support the growing need for increased fuel flexibility.

Assessment of On-Site Power Opportunities in the Industrial Sector; TOPICAL

Bryson, T.

2001-01-01

The purpose of this report is to identify the potential for on-site power generation in the U.S. industrial sector with emphasis on nine industrial groups called the ''Industries of the Future'' (IOFs) by the U.S. Department of Energy (DOE). Through its Office of Industrial Technologies (OIT), the DOE has teamed with the IOFs to develop collaborative strategies for improving productivity, global competitiveness, energy usage and environmental performance. Total purchases for electricity and steam for the IOFs are in excess of$27 billion annually. Energy-related costs are very significant for these industries. The nine industrial groups are: (1) Agriculture (SIC 1); (2) Forest products; (3) Lumber and wood products (SIC 24); (4) Paper and allied products (SIC 26); (5) Mining (SIC 11, 12, 14); (6) Glass (SIC 32); (7) Petroleum (SIC 29); (8) Chemicals (SIC 28); and (9) Metals (SIC 33)-Steel, Aluminum, Metal casting. Although not currently part of the IOF program, the food industry is included in this report because of its close relationship to the agricultural industry and its success with on-site power generation. On-site generation provides an alternative means to reduce energy costs, comply with environmental regulations, and ensure a reliable power supply. On-site generation can ease congestion in the local utility's electric grid. Electric market restructuring is exacerbating the price premium for peak electricity use and for reliability, creating considerable market interest in on-site generation

Getting the right balance between regulation and governance in the non-bank financial sector

2012-10-01

Full Text Available This paper uses the example of the collapse of the finance company sector in New Zealand in 2006-2010 to illustrate the problems with light touch regulation and a reliance on good governance to ensure financial stability. It shows two major governance failures, the first in the governance of the sector by the authorities and the second, serious failures in corporate governance by the firms involved. While a light touch may assist economic development it also increases fragility. New Zealand has now switched to a greater emphasis on regulation and to a better alignment of incentives to ensure good governance. While other countries might consider implementing aspects of its new bank resolution regime most are opting for considerably more regulation and compliance costs.

Renewable energy and CCS in German and European power sector decarbonization scenarios

Energy Technology Data Exchange (ETDEWEB)

Ludig, Sylvie

2013-11-06

In order to avoid unmanageable impacts of anthropogenic climate change, it is necessary to achieve substantial CO{sub 2} emission reductions in all energy sectors. Due to salient decarbonization options such as renewable energy technologies and carbon capture and storage (CCS), the power sector plays a major role in climate change mitigation strategies. However, these options come with a set of challenges: the output of wind and solar energy varies in time and space and CCS faces technical challenges and public acceptance problems. This thesis develops power sector decarbonization scenarios for the EU and Germany while taking into account both the interplay of renewable energy technologies and CCS as mitigation options as well as the technical challenges of renewable energy integration. More specifically, a series of model based studies address the respective roles of CCS and renewable energy technologies in emission reduction strategies while evaluating technical integration options such as transmission, storage and balancing technologies. Results show that large-scale expansion of renewable energies will play the main role in power sector decarbonization scenarios, but the availability of CCS could lead to lower total costs and easier reaching of emission reduction targets through compensation of emissions generated by balancing technologies. Long-distance transmission enables better siting of renewable energy and thus higher achievable renewable shares in power generation and higher capacity factors. These indirect effects of delayed expansions induce additional power system costs, which are high relative to investment costs for new transmission lines. Results also reveal a preference for flexible technologies in combination with high shares of renewables for balancing purposes rather than inflexible baseload plants. A case study for the EU shows that a near-complete decarbonization is possible both with and without transmission expansions, but total power

The European Union aims to reduce greenhouse gas emissions by 80–95% in 2050 compared to 1990 levels. The transition towards a low-carbon economy implies the almost complete decarbonization of Europe's power sector, which could be achieved along various pathways. In this paper, we evaluate the economic implications of alternative energy policies for Europe's power sector by applying a linear dynamic electricity system optimization model in over 36 scenarios. We find that the costs of decarbonizing Europe's power sector by 2050 vary between 139 and 633 bn € 2010 , which corresponds to an increase of between 11% and 44% compared to the total system costs when no CO 2 reduction targets are implemented. In line with economic theory, the decarbonization of Europe's power sector is achieved at minimal costs under a stand-alone CO 2 reduction target, which ensures competition between all low-carbon technologies. If, however, renewable energies are exempted from competition via supplementary renewable energy (RES-E) targets or if investments in new nuclear and CCS power plants are politically restricted, the costs of decarbonization significantly rise. Moreover, we find that the excess costs of supplementary RES-E targets depend on the acceptance of alternative low carbon technologies. For example, given a complete nuclear phase-out in Europe by 2050 and politically implemented restrictions on the application of CCS to conventional power plants, supplementary RES-E targets are redundant. While in such a scenario the overall costs of decarbonization are comparatively high, the excess costs of supplementary RES-E targets are close to zero. - Highlights: • We evaluate the economic implications of alternative energy policies for Europe's power sector. • Total decarbonization costs vary between 139 and 633 billion € 2010 up to 2050. • Decarbonization at minimal costs is ensured by competition between all low carbon technologies. • Excess costs of supplementary

Power sector is the largest CO 2 emitter in China. To mitigate CO 2 emissions for the power sector is a tough task, which requires implementation of targeted carbon mitigation policies. There might be multiple forms for carbon mitigation policies and it is still unclear which one is the best for China. Applying a superstructure optimisation model for optimal planning of China's power sector built by the authors previously, which was based on real-life plants composition data of China's power sector in 2009, and could incorporate all possible actions of the power sector, including plants construction, decommission, and application of carbon capture and sequestration (CCS) on coal-fuelled plants, the implementation effects of three carbon mitigation policies were studied quantitatively, achieving a conclusion that the so-called “Surplus-Punishment and Deficit-Award” carbon tax policy is the best from the viewpoint of increasing CO 2 reduction effect and also reducing the accumulated total cost. Based on this conclusion, the corresponding relationships between CO 2 reduction objectives (including the accumulated total emissions reduction by the objective year and the annual emissions reduction in the objective year) were presented in detail. This work provides both directional and quantitative suggestions for China to make carbon mitigation policies in the future. - Highlights: ► We study the best form of carbon mitigation policy for China's power sector. ► We gain quantitative relationship between CO 2 reduction goal and carbon tax policy. ► The “Surplus-Punishment and Deficit-Award” carbon tax policy is the best. ► Nuclear and renewable power and CCS can help greatly reduce CO 2 emissions of the power sector. ► Longer objective period is preferred from the viewpoint of policy making.

An analysis of Grenada's power sector and energy resources: a role for renewable energy technologies?

International Nuclear Information System (INIS)

Wiesser, D.

2004-01-01

Presently, Grenada's power sector is fully dependent on fossil fuel imports for meeting the country's electricity demand. Electric utilities in Small Island Developing States (SIDS), in general, face high cost of electricity generation due to diseconomies of scale in production, consumption and logistical aspects. Grenada's private power monopoly is no exception and the high cost of import dependent electricity generation places an increasing burden on economic development. In light of rapid technological and economic improvement of renewable energy technologies (RETs), the country's abundant sources of renewable energy should be harnessed. Benefits are envisaged to include lower electricity cost, better environmental performance and a safer and diversified supply of energy. However, barriers for shifting power production towards meaningful contributions from RETs exist, both in government and industry. This work analyses important economic interactions between the power sector and economic development, bringing to attention the importance of power sector reform. Further, present problems of integrating RETs into the grid, ranging from technical and regulatory issues to shareholder interest are investigated. A summary and analysis of past research into renewable sources of energy (RES) underscore the potential for power production from RETs in Grenada. (author)

REALIZATION OF INVESTMENT PROJECTS IN POWER GENERATION SECTOR AND DETERMINATION OF CAPITAL INVESTMENT SOURCES

Directory of Open Access Journals (Sweden)

V. N. Nagornov

2008-01-01

Full Text Available The paper contains information on the basic directions of an investment activity in the power generation sector of the Republic of Belarus and importance of the realization of planned actions at the present moment. The main sources for financing modernization of basic production funds of the Belarusian power generation system have been analyzed in the paper. The paper describes general problems and difficulties that the power industry is facing while realizing investment projects. The most important problem is a formation of sources for complete project financing due to sharp price rise for imported power resources. The paper considers various approaches to provision of the required sources for financing investment activity in the power sector. The paper shows the need for a tariff policy reform, which is to be aimed, first of all, at the reduction of the cross subsidizing in power tariffs.

CO2 abatement policies in the power sector under an oligopolistic gas market

International Nuclear Information System (INIS)

Hecking, Harald

2014-01-01

The paper at hand examines the power system costs when a coal tax or a fixed bonus for renewables is combined with CO 2 emissions trading. It explicitly accounts for the interaction between the power and the gas market and identifies three cost effects: First, a tax and a subsidy both cause deviations from the cost-efficient power market equilibrium. Second, these policies also impact the power sector's gas demand function as well as the gas market equilibrium and therefore have a feedback effect on power generation quantities indirectly via the gas price. Thirdly, by altering gas prices, a tax or a subsidy also indirectly affects the total costs of gas purchase by the power sector. However, the direction of the change in the gas price, and therefore the overall effect on power system costs, remains ambiguous. In a numerical analysis of the European power and gas market, I find using a simulation model integrating both markets that a coal tax affects gas prices ambiguously whereas a fixed bonus for renewables decreases gas prices. Furthermore, a coal tax increases power system costs, whereas a fixed bonus can decrease these costs because of the negative effect on the gas price. Lastly, the more market power that gas suppliers have, the stronger the outlined effects will be.

Renewable energies and competition in the power economy. Governmental regulation - comparison between Germany and Great Britain; Erneuerbare Energien und Wettbewerb in der Elektrizitaetswirtschaft. Staatliche Regulierung im Vergleich zwischen Deutschland und Grossbritannien

Throughout Europe the energy economy faces two major challenges from new governmental regulation, namely regulation for the purposes of climate policy and regulation for the introduction of competition to what used to be monopolistic sectors. With regard to the growing regulatory influence of the European Union the author of this British-German comparative study analyses how diverging structures of governmental organisation and historical paths of development have led to different regulatory approaches to the market introduction of renewable energies and the liberalisation of the power economy. He offers an in-depth analysis of the differences in success the two countries success have had in developing sustainable electricity production systems and establishing competitive structures in the power sector.

Twenty years nuclear power sector in Bulgaria - an attempt at striking a balance

Shervashidze, N.

1994-01-01

The advantages of nuclear power and the mistakes that cause the opposition against it on the example of the history of the Bulgarian nuclear power sector are considered in a polemical manner. Four WWER 440/230 and two WWER 1000 units have been put into operation in Kozloduj NPP in the period 1974 - 1993. Before 1991, however, safety operation criteria were compromised numerous times and the atmosphere of secrecy, self-complacency and the series of absurdities about the Chernobyl accident were clearly used by the opponents of nuclear energy. Now the attitude towards nuclear power is changing for the better. Much progress has been made in recovering the nuclear power sector under complicated economic and political conditions. The role of NPP as an anti-inflation factor, an element providing the national security, a stimulator of industry and infrastructure, and an ecological salvation factor, is stressed. (I.M.)

Coordination and decision making of regulation, operation, and market activities in power systems

Science.gov (United States)

Nakashima, Tomoaki

Electric power has been traditionally supplied to customers at regulated rates by vertically integrated utilities (VIUs), which own generation, transmission, and distribution systems. However, the regulatory authorities of VIUs are promoting competition in their businesses to lower the price of electric energy. Consequently, in new deregulated circumstances, many suppliers and marketers compete in the generation market, and conflict of interest may often occur over transmission. Therefore, a neutral entity, called an independent system operator (ISO), which operates the power system independently, has been established to give market participants nondiscriminatory access to transmission sectors with a natural monopoly, and to facilitate competition in generation sectors. Several types of ISOs are established at present, with their respective regions and authorities. The ISO receives many requests from market participants to transfer power, and must evaluate the feasibility of their requests under the system's condition. In the near future, regulatory authorities may impose various objectives on the ISOs. Then, based on the regulators' policies, the ISO must determine the optimal schedules from feasible solutions, or change the market participants' requests. In a newly developed power market, market participants will conduct their transactions in order to maximize their profit. The most crucial information in conducting power transactions is price and demand. A direct transaction between suppliers and consumers may become attractive because of its stability of price, while in a power exchange market, gaming and speculation of participants may push up electricity prices considerably. To assist the consumers in making effective decisions, suitable methods for forecasting volatile market price are necessary. This research has been approached from three viewpoints: Firstly, from the system operator's point of view, desirable system operation and power market structure

2008-12-01

The main objective of the present study is to analyse the implications of shifting from free allocation to auctioning of EU ETS allowances (EUAs) for the power sector in the Netherlands. In order to achieve this objective, this study has used three methodological approaches, including theoretical, empirical and model analyses of the impact of free allocations versus auctioning of EUAs on the power sector, notably in the Netherlands. In addition, as Combined Heat and Power (CHP) plays a major role in the electricity sector of the Netherlands, the present study also pays some particular attention to the implications of shifting from free allocation to EUA auctioning for the CHP sector in the Netherlands

Nuclear power reactors are, in nature nonlinear and time varying. These characteristics must be considered, if large power variations occur in their working regime. In this paper a robust optimal self-tuning regulator for regulating the power of a nuclear reactor has been designed and simulated. The proposed controller is capable of regulating power levels in a wide power range (10% to 100% power levels). The controller achieves a fast and good transient response. The simulation results show that the proposed controller outperforms the fixed optimal control recently cited in the literature for nuclear power plants

Meyers, S.; Goldman, N.; Martin, N.; Friedmann, R.

1993-04-01

Based on information drawn primarily from official planning documents issued by national governments and/or utilities, the authors examined the outlook for the power sector in the year 2000 in nine countries: China, India, Indonesia, Thailand, the Philippines, South Korea, Taiwan, Argentina and Mexico. They found that the implicit rates of average annual growth of installed electric power capacity between 1991 and 2001 range from a low of 3.3% per year in Argentina to a high of 13.2% per year in Indonesia. In absolute terms, China and India account for the vast majority of the growth. The plans call for a shift in the generating mix towards coal in six of the countries, and continued strong reliance on coal in China and India. The use of natural gas is expected to increase substantially in a number of the countries. The historic movement away from oil continues, although some countries are maintaining dual-fuel capabilities. Plans call for considerable growth of nuclear power in South Korea and China and modest increases in India and Taiwan. The feasibility of the official plans varies among the countries. Lack of public capital is leading towards greater reliance on private sector participation in power projects in many of the countries. Environmental issues are becoming a more significant constraint than in the past, particularly in the case of large-scale hydropower projects. The financial and environmental constraints are leading to a rising interest in methods of improving the efficiency of electricity supply and end use. The scale of such activities is growing in most of the study countries.

'Nuclearelectrica' and restructuring the electric power sector in Romania

International Nuclear Information System (INIS)

Metes, Mircea

2001-01-01

The paper presents the first steps of the energy market development in Romania and the impact of this process on 'Nuclearelectrica' company which operates the Cernavoda NPP. The main directions of the power sector liberalization in the European Union are being implemented in Romania. 'Nuclearelectrica' attempts to comply with both economic and safety requirements for nuclear plant operation. So far, the evolution of power market proved the competitiveness of Cernavoda Unit 1 with the existing power producers in Romania. It is stressed that although the 'Hydroelectrica' company sells the MWh at a lower price it cannot cope with top demands higher than 2400 MW. Economical aspects are analyzed and the conclusion is drawn that the situation of 'Nuclearelectrica' company will be significantly changed after the commissioning of Cernavoda Unit 2. (author)

This 2010 series of power company and thematic fact sheets aims to raise public awareness about sustainability issues in the electricity sector and to improve the sustainability of power companies operating in the Netherlands. The fact sheet series investigates the companies' performance on incorporating renewable energy sources into their fuel mix for both generation and supply of electricity, and on their investments and future plans with respect to energy sources at both the Dutch and European level. The 2010 fact sheet series is the annual update that is going into its fourth year, and builds on the work from previous years (available at www.somo.nl), but includes a slightly different range of companies due to a number of recent and pending mergers and acquisitions among power companies with operations in the Netherlands.

Reform despite politics? The political economy of power sector reform in Fiji, 1996–2013

International Nuclear Information System (INIS)

Dornan, Matthew

2014-01-01

Attempts to reform the electricity sector in developing countries have achieved mixed results, despite the implementation of similar reforms in many developed countries, and concerted effort by donors to transfer reform models. In many cases, political obstacles have prevented full and effective implementation of donor-promoted reforms. This paper examines the political economy of power sector reform in Fiji from 1996 to 2013. Reform has been pursued with political motives in a context of clientelism. Policy inconsistency and reversal is explained by the political instability of ethnic-based politics in Fiji. Modest success has been achieved in recent years despite these challenges, with Fiji now considered a model of power sector reform for other Small Islands Developing States (SIDS) in the Pacific. The experience demonstrates that reform is possible within difficult political environments, but it is challenging, takes time and is not guaranteed. The way in which political motives have driven and shaped reform efforts also highlights the need for studies of power sector reform to direct greater attention toward political drivers behind reform. - Highlights: • This is the first study of power sector reform in Fiji or other Small Island Developing States (SIDS) of the Pacific. • The clientelist nature of politics in Fiji is found to have both driven and shaped reform efforts. • There has been modest success in recent years despite these obstacles, with Fiji now considered a model for other SIDS. • The experience demonstrates that reform is possible within difficult political environments, but it is challenging, takes time and is not guaranteed

Incorporating global warming risks in power sector planning: A case study of the New England region

International Nuclear Information System (INIS)

Krause, F.; Busch, J.; Koomey, J.

1992-11-01

Growing international concern over the threat of global climate change has led to proposals to buy insurance against this threat by reducing emissions of carbon (short for carbon dioxide) and other greenhouse gases below current levels. Concern over these and other, non-climatic environmental effects of electricity generation has led a number of states to adopt or explore new mechanisms for incorporating environmental externalities in utility resource planning. For example, the New York and Massachusetts utility commissions have adopted monetized surcharges (or adders) to induce emission reductions of federally regulated air pollutants (notably, SO 2 , NO x , and particulates) beyond federally mandated levels. These regulations also include preliminary estimates of the cost of reducing carbon emissions, for which no federal regulations exist at this time. Within New England, regulators and utilities have also held several workshops and meetings to discuss alternative methods of incorporating externalities as well as the feasibility of regional approaches. This study examines the potential for reduced carbon emissions in the New England power sector as well as the cost and rate impacts of two policy approaches: environmental externality surcharges and a target- based approach. We analyze the following questions: Does New England have sufficient low-carbon resources to achieve significant reductions (10% to 20% below current levels) in fossil carbon emissions in its utility sector? What reductions could be achieved at a maximum? What is the expected cost of carbon reductions as a function of the reduction goal? How would carbon reduction strategies affect electricity rates? How effective are environmental externality cost surcharges as an instrument in bringing about carbon reductions? To what extent could the minimization of total electricity costs alone result in carbon reductions relative to conventional resource plans?

Data on the future electricity demand is an essential requirement for planning the expansion of a power system. The purpose of this study is to provide a general overview of electricity consumption in Bangladesh, forecast sector-wise electricity demand up to 2035 considering the base year 2005, and compare the results with official projections. The Long-range Energy Alternative Planning (LEAP) model with three scenarios, namely low gross domestic product (GDP) growth, average GDP growth and high GDP growth, is applied in this study. In the low to high GDP growth scenarios, the extent of industrial restructuring and technical advancement is gradually increased. The findings have significant implications with respect to energy conservation and economic development. The study also compares the projected per capita electricity consumption in Bangladesh with the historical growth in several other developing countries. Such an evaluation can create awareness among the planners of power system expansion in Bangladesh to meet the high future demand.

Status of power sector restructuring in Lithuania

Bachiauskas, A.

1999-01-01

Lithuanian electricity sector comprises joint stock company Lietuvos Energija, which is responsible for supplying the country with electric energy, the Ignalina NPP state enterprise, which generates more then three fourth of the entire electricity of Lithuania, CHPs run By municipalities of Kaunas and Vilnius, and a few power plants, owned by industrial enterprises, as well as private small hydro power plants. Joint stock company Lietuvos Energija is a vertically integrated monopoly, which has inherited drawbacks inherent in planned - administrational economy and is therefore now being restructured into a modern and effective structure capable of operating within market economy conditions. The main goals of restructuring would meet electricity economy requirements: clearly un bundle electricity generation costs from electricity transmission and distribution costs; create internal and external electricity market conditions by gradual transition to wholesale and retail electricity trade; create conditions for third party access; create favourable conditions for competition; provide a possibility to integrate with Baltic electricity market in progress

Competing Air Quality and Water Conservation Co-benefits from Power Sector Decarbonization

Decarbonizing the power sector can reduce fossil-based generation and associated air pollution and water use. However, power sector configurations that prioritize air quality benefits can be different from those that maximize water conservation benefits. Despite extensive work to optimize the generation mix under an air pollution or water constraint, little research has examined electricity transmission networks and the choice of which fossil fuel units to displace in order to achieve both environmental objectives simultaneously. When air pollution and water stress occur in different regions, the optimal transmission and displacement decisions still depend on priorities placed on air quality and water conservation benefits even if low-carbon generation planning is fixed. Here we use China as a test case, and develop a new optimization framework to study transmission and displacement decisions and the resulting air quality and water use impacts for six power sector decarbonization scenarios in 2030 ( 50% of national generation is low carbon). We fix low-carbon generation in each scenario (e.g. type, location, quantity) and vary technology choices and deployment patterns across scenarios. The objective is to minimize the total physical costs (transmission costs and coal power generation costs) and the estimated environmental costs. Environmental costs are estimated by multiplying effective air pollutant emissions (EMeff, emissions weighted by population density) and effective water use (Weff, water use weighted by a local water stress index) by their unit economic values, Vem and Vw. We are hence able to examine the effect of varying policy priorities by imposing different combinations of Vem and Vw. In all six scenarios, we find that increasing the priority on air quality co-benefits (higher Vem) reduces air pollution impacts (lower EMeff) at the expense of lower water conservation (higher Weff); and vice versa. Such results can largely be explained by differences

July 19, 1999, the Netherlands Electricity Regulatory Service ('Dienst uitvoering en toezicht elektriciteitswet Dte) issued the consultation document 'Price-cap regulation in the electric power sector'. The document is strongly based on a modern, UK inspired method of regulation. The methods, as proposed in the document, will have an impact on the final electricity tariffs, and thus of great importance for the consumers and the businesses involved. In this article the most striking element in the consultation document is discussed: how to determine the X (i.e. the expected growth of the productivity) in the price-cap regulation

Internationally, there is wide cross-country heterogeneity in government responses to dual practice in the health sector. This paper provides a uniform theoretical framework to analyze and compare some of the most common regulations. We focus on three interventions: banning dual practice, offering rewarding contracts to public physicians, and limiting dual practice (including both limits to private earnings of dual providers and limits to involvement in private activities). An ancillary objective of the paper is to investigate whether regulations that are optimal for developed countries are adequate for developing countries as well. Our results offer theoretical support for the desirability of different regulations in different economic environments. Copyright © 2012 Elsevier B.V. All rights reserved.

Bautista, Santiago

2012-01-01

The present research study used the quantitative approach to analyze the present and future situation of the Venezuelan power generation sector; to achieve that, the total energy generation costs and GHG emissions of four scenarios in 2050 were estimated and compared, considering two demand groups, high and low demand. For each demand scenario, two supply matrix were considered, a generation matrix based on the existing national power generation plans and trends (these scenarios were referred as BAU) and a configuration based on the renewable energy resources available in Venezuela and without the use of either nuclear or CCS technologies, and these scenarios are referred as Sustainable Scenarios (SUS). In the first section, the present situation is presented, followed by an explanation of the applied methodology and the implemented tools. In the third and fourth sections the available recourses and the applied basic assumptions for the four of scenarios are presented and discussed, respectively, followed by the results. In this study it is shown that Venezuela has all the resources it needs to achieve sustainable development in the power generation sector. It is also proved that an energy efficiency improvement is the easiest path to reduce GHG emissions. - Highlights: ► Venezuela has enough energy resources to supply the energy require for its development. ► A sustainable scenario is posible in Venezuelan power generation sector in 2050. ► The sustainable scenario is technically possible without nuclear power or carbon capture storage technologies. ► The impact over the depleatable resources is higher under the BAU assumptions.

Quantifying the Impacts of Large Scale Integration of Renewables in Indian Power Sector

India's power sector is responsible for nearly 37 percent of India's greenhouse gas emissions. For a fast emerging economy like India whose population and energy consumption are poised to rise rapidly in the coming decades, renewable energy can play a vital role in decarbonizing power sector. In this context, India has targeted 33-35 percent emission intensity reduction (with respect to 2005 levels) along with large scale renewable energy targets (100GW solar, 60GW wind, and 10GW biomass energy by 2022) in INDCs submitted at Paris agreement. But large scale integration of renewable energy is a complex process which faces a number of problems like capital intensiveness, matching intermittent loads with least storage capacity and reliability. In this context, this study attempts to assess the technical feasibility of integrating renewables into Indian electricity mix by 2022 and analyze its implications on power sector operations. This study uses TIMES, a bottom up energy optimization model with unit commitment and dispatch features. We model coal and gas fired units discretely with region-wise representation of wind and solar resources. The dispatch features are used for operational analysis of power plant units under ramp rate and minimum generation constraints. The study analyzes India's electricity sector transition for the year 2022 with three scenarios. The base case scenario (no RE addition) along with INDC scenario (with 100GW solar, 60GW wind, 10GW biomass) and low RE scenario (50GW solar, 30GW wind) have been created to analyze the implications of large scale integration of variable renewable energy. The results provide us insights on trade-offs involved in achieving mitigation targets and investment decisions involved. The study also examines operational reliability and flexibility requirements of the system for integrating renewables.

2010-06-01

Full Text Available This article argues that the conceptualisation of private police in current academic literature requires expansion to accommodate the role of the regulated sector in the Anti- Money Laundering (AML framework. Firstly, it evaluates the literature on ‘private police’ and argues that its current parameters are too narrow to accommodate the ‘policing’ role of the regulated sector. Secondly, it lays out the legislative framework that has developed to deal with the problem of money laundering. Thirdly, it contextualises the role of the regulated sector, examining the domestic inter-agency policing relationships within the suspicious activity regime as operationalised in Scotland. Finally, it takes a closer look at how the courts have interpreted the ‘failure to report offence’ under s330 of the Proceeds of Crime Act (POCA 2002 and its consequential effect on the engagement of the regulated sector with the SARs regime.

The Water-Use Implications of a Changing Power Sector

Peer, R.; Sanders, K.

Changing policies, declining natural gas prices due to shale production and, growing pressure for cleaner energy sources are causing significant shifts in the fuels and technologies utilized for US electricity generation. These shifts have already impacted the volumes of water required for cooling thermal power plants, imposing consequences for watersheds that have yet to be quantified. This research investigates how these regulatory, economic, and socially-driven changes in the power sector have impacted cooling water usage across the US, which currently represents nearly half of US water withdrawals. This study uses plant-specific fuel consumption, generation, and cooling water data to assess water usage trends in the power sector from 2008 to 2014 across HUC-8 hydrologic units. Over this period, transitions from steam-cycle coal and nuclear units towards combined-cycle natural gas units and renewables, as well as transitions from once-through cooling towards wet recirculating tower and dry cooling systems resulted in large shifts in water usage. Trends towards non-traditional cooling water sources such as recycled water reduced freshwater consumption in some watersheds. Although US cooling water withdrawals and consumption increased from 2008 to 2014 largely due to electricity demand growth, the average water withdrawn and consumed per unit of electricity generated decreased and remained similar in magnitude, respectively. Changes at the watershed scale were not uniform, with some experiencing significant water use reductions and environmental benefits, especially due to coal-fired power plant retirements. Results highlight the importance of evaluating both water withdrawals and consumption at local spatial scales, as these shifts have varying consequences on water availability and quality for downstream users and ecosystems. This analysis underscores the importance of prioritizing local water security in global climate change adaptation and mitigation efforts.

The regulating power market on the Nordic power exchange Nord Pool. An econometric analysis

International Nuclear Information System (INIS)

Skytte, K.

1999-08-01

What differentiates the structure of Nord Pool from other power exchanges around the world is the way the balance from the spot market is maintained until the actual, physical delivery takes place, via the regulating power market in Norway. This paper reveals the pattern of the prices on the regulating power market, by analysing the cost of being unable to fulfil the commitments made on the spot market. Some power producers with unpredictable fluctuations (e.g. wind) will need to buy regulation services. The disclosed pattern implies that these producers must pay a limited premium of readiness in addition to the spot price; this premium is independent of the amount of regulation. The level of the premium of readiness for down-regulation is shown to be strongly influenced by the level of the spot price. On the other hand, it is demonstrated that the premium for up-regulation is less correlated to the spot price. Furthermore, it is found that the amount of regulation affects the price of regulating power for up-regulation more strongly than it does for down-regulation. The disclosed cost of using the regulating power market is a quadratic function of the amount of regulation. This asymmetric cost may encourage bidders with fluctuating production to be more strategic in their way of bidding on the spot market. By using such strategies the extra costs (for example wind power) needed to counter unpredictable fluctuations may be limited. 12 refs

The Norwegian power sector is undergoing basic changes. All the energy utilities are affected. This report describes the options faced by the owners and the effects of making different choices. It (1) discusses the implications of competition and the new external conditions for publicly owned utilities, (2) analyses the profit obtainable through cooperation and changes in the structure within production, power sale and network activities, and (3) draws up the perspectives of the future structure of the power sector in eastern Norway, where many of the largest suppliers are situated. Two scenarios are discussed for the structure of the power sector in eastern Norway in 2010: (1) Regional focus. The owners have a deliberate attitude to the possibilities of a publicly owned and competitive energy supply and they want to exploit the economic potential to the benefit of the inhabitants of the region. The energy users are offered services that are competitive both on price and quality and the policy instrument is to develop regional solutions that realize the possibilities of large-scale operation and coordination within production, sales and network. (2) Industrial energy supply. Large industrial actors have won most of the auctions as the smaller distribution works were offered for sale. Both scenarios are rooted in changes that have actually occurred or are still in progress. There is no socioeconomic justification for asserting that one scenario is better than the other. The choice of action taken by the owners will first of all affect the distribution of the values managed and created by the power sector. 27 figs., 12 tabs.

Coal transitions in China's power sector: A plant-level assessment of stranded assets and retirement pathways

International Nuclear Information System (INIS)

Spencer, Thomas; Berghmans, Nicolas; Sartor, Oliver

2017-11-01

This paper estimates the potential scale of stranded assets in the coal power sector in China under different policy scenarios. A number of factors are putting significant pressure on the coal-power sector: a recent investment bubble in new capacity, structural slowing in electricity demand growth, upcoming moves to liberalize electricity markets and introduce a carbon market, and continued support for renewable and low-carbon sources of electricity. Stranded assets in the Chinese coal-fired power sector are estimated at 90 billion USD 2015 under the current policy trajectory (NDC-Style Scenario). This situation threatens to increase the political economy challenges of China's electricity sector transition to a low-carbon system. This situation is not unique to China: other countries will also face coal-sector stress due to the competitiveness of renewables, and therefore managing existing coal power capacities needs to move to the forefront of climate and energy policy efforts. To turn this situation around, Chinese authorities should have a strategy for a managed phase-down of coal power assets. All new construction of coal power plants should cease: recent project cancellations have been a step in the right direction. A planned retirement schedule for old coal plants that have already made a return on investment should be developed to 2030. Existing, newer coal plants should be prepared to play a role and receive revenues for balancing a high renewables system. A managed 2 deg. C-compatible climate mitigation scenario, in which old plant are retired after 30 years, both puts China's electricity sector on an accelerated pathway to decarbonization, as well as lowering the risks of stranded assets compared to the NDC-Style Scenario, by a total of 12 billion USD 2015. Banking sector exposure to stranded assets in the Managed 2 deg. C Scenario are estimated at less than 10% of the banking sector's loan loss provisions: risks of financial disruption are

2006-12-15

With the fastest growing energy demand in the world, China is now the largest electricity consumer after the United States. How can the government best assure affordable and environmentally sustainable electricity supply in the future? The Chinese government has initiated electricity sector reforms to overhaul an antiquated system and attain new energy security and environmental objectives. How China proceeds with these reforms will have lasting consequences, both locally and globally. Assessing the current state of electricity regulation in China, this report draws on experience elsewhere to explore how better to develop and communicate strategy, how to moderate growth in demand through increased efficiency, how to integrate environmental goals into planning and operation, how to ensure sufficient supply when and where it is needed, and how to handle institutional and governance challenges. In this respect, electricity sector reform in other countries offers valuable lessons as to how China might proceed.

The independent power production and the reorganization of the electric power sector

International Nuclear Information System (INIS)

1998-12-01

The transformation of the electric power production and distribution sector is in progress thanks to the progressive opening of markets and to the emergence of a new kind of actor: the independent producer. After the USA, the UK, and most of the emerging countries, the continental Europe is actively preparing its mutation. The historical actors try to protect their positions on their own national markets and at the same time to develop their international position. The newcomers (oil companies, independent power producers, collective service companies) have adopted a radically offensive strategy based on an international development and a skimming of the market. This study takes stock of the degree of liberalization of the different markets and analyzes their structuring elements and dynamism. An analytical presentation of the main actors of the electric power market is performed in order to evaluate their forces and feeblenesses in front of this mutation. Finally, it tries to answer the following questions: which are the most promising zones for the newcomers, and which companies will win this new deal? (J.S.)

Substation Reactive Power Regulation Strategy

Zhang, Junfeng; Zhang, Chunwang; Ma, Daqing

2018-01-01

With the increasing requirements on the power supply quality and reliability of distribution network, voltage and reactive power regulation of substations has become one of the indispensable ways to ensure voltage quality and reactive power balance and to improve the economy and reliability of distribution network. Therefore, it is a general concern of the current power workers and operators that what kind of flexible and effective control method should be used to adjust the on-load tap-changer (OLTC) transformer and shunt compensation capacitor in a substation to achieve reactive power balance in situ, improve voltage pass rate, increase power factor and reduce active power loss. In this paper, based on the traditional nine-zone diagram and combining with the characteristics of substation, a fuzzy variable-center nine-zone diagram control method is proposed and used to make a comprehensive regulation of substation voltage and reactive power. Through the calculation and simulation of the example, this method is proved to have satisfactorily reconciled the contradiction between reactive power and voltage in real-time control and achieved the basic goal of real-time control of the substation, providing a reference value to the practical application of the substation real-time control method.

Power sector scenarios for Thailand: An exploratory analysis 2002-2022

International Nuclear Information System (INIS)

Mulugetta, Yacob; Mantajit, Nathinee; Jackson, Tim

2007-01-01

Power sector scenarios for Thailand are constructed in this paper to represent the range of opportunities and constraints associated with divergent set of technical and policy options. They include Business-As-Usual (BAU), No-New-Coal (NNC), and Green Futures (GF) scenarios over a 20-year period (2002-2022). The results from the BAU scenario show that fossil fuels will continue to dominate electricity generation in Thailand during the study period. Similar results are obtained for the NNC option, although the dependence shifts from coal and oil towards natural gas-based power generation. This may represent a better environmental pathway but an all out shift from coal to natural gas is likely to increase Thailand's dependence on imported fuel, making it more vulnerable to unstable global oil and gas prices. The GF scenario offers a more optimistic route that allows the country to confront its energy security dilemma whilst fulfilling its environmental commitments by giving renewable energy technologies a prominent place in the country's power generation mix. Over the study period, our result showed little difference between the three scenarios in terms of financing new generation plants despite an early misgiving about the viability of an ambitious renewable energy programme. This paper also goes beyond the financial evaluation of each scenario to provide a comparison of the scenarios in terms of their greenhouse gas emissions together with the comparative costs of emissions reductions. Indeed, if such externalities are taken into account to determine 'viability', the GF scenario represents an attractive way forward for the Thai power sector

Power sector reforms in Ethiopia: options for promoting local investments in rural electrification

Energy Technology Data Exchange (ETDEWEB)

Teferra, Mengistu [Ministry of Economic Development and Co-operation, Addis Ababa (Ethiopia)

2002-09-01

An estimated 13% of Ethiopia's population has access to electricity. Almost all electrified centres are urban, with rural areas as well as most small rural towns largely unelectrified. Rural electrification (RE) thus remains a major challenge to the power sector of Ethiopia. The national power utility (EEPCO) has traditionally been assigned the task of electrifying rural demand centres. EEPCO has, however, concentrated on the more developed and profitable urban areas. The objective of this article is to present the findings of a study that examined whether the ongoing power sector reforms in Ethiopia can attract private investment in RE as an alternative to the sole reliance on EEPCO. Initial findings of the study indicate that private investment in RE can be enhanced with some improvement in the legal and regulatory provisions, along with extension of technical assistance from EEPCO to private investors.

Oda, Takuya; Akisawa, Atushi; Kashiwagi, Takao

If the economic activity in the commercial and residential sector continues to grow, improvement in energy conversion efficiencies of energy supply systems is necessary for CO2 mitigation. In recent years, the electricity driven hot water heat pump (EDHP) and the solar photo voltaic (PV) are commercialized. The fuel cell (FC) of co-generation system (CGS) for the commercial and residential sector will be commercialized in the future. The aim is to indicate the ideal energy supply system of the users sector, which both manages the economical cost and CO2 mitigation, considering the grid power system. In the paper, cooperative Japanese energy supply systems are modeled by linear-programming. It includes the grid power system and energy systems of five commercial sectors and a residential sector. The demands of sectors are given by the objective term for 2005 to 2025. 24 hours load for each 3 annual seasons are considered. The energy systems are simulated to be minimize the total cost of energy supply, and to be mitigate the CO2 discharge. As result, the ideal energy system at 2025 is shown. The CGS capacity grows to 30% (62GW) of total power system, and the EDHP capacity is 26GW, in commercial and residential sectors.

Electric power and the global economy: Advances in database construction and sector representation

Science.gov (United States)

Peters, Jeffrey C.

The electricity sector plays a crucial role in the global economy. The sector is a major consumer of fossil fuel resources, producer of greenhouse gas emissions, and an important indicator and correlate of economic development. As such, the sector is a primary target for policy-makers seeking to address these issues. The sector is also experiencing rapid technological change in generation (e.g. renewables), primary inputs (e.g. horizontal drilling and hydraulic fracturing), and end-use efficiency. This dissertation seeks to further our understanding of the role of the electricity sector as part of the dynamic global energy-economy, which requires significant research advances in both database construction and modeling techniques. Chapter 2 identifies useful engineering-level data and presents a novel matrix balancing method for integrating these data in global economic databases. Chapter 3 demonstrates the relationship between matrix balancing method and modeling results, and Chapter 4 presents the full construction methodology for GTAP-Power, the foremost, publicly-available global computable general equilibrium database. Chapter 5 presents an electricity-detailed computational equilibrium model that explicitly and endogenously captures capacity utilization, capacity expansion, and their interdependency - important aspects of technological substitution in the electricity sector. The individual, but interrelated, research contributions to database construction and electricity modeling in computational equilibrium are placed in the context of analyzing the US EPA Clean Power Plan (CPP) CO 2 target of 32 percent reduction of CO2 emissions in the US electricity sector from a 2005 baseline by 2030. Assuming current fuel prices, the model predicts an almost 28 percent CO2 reduction without further policy intervention. Next, a carbon tax and investment subsidies for renewable technologies to meet the CPP full targets are imposed and compared (Chapter 6). The carbon tax

Malaysia is still working on continuing its economic growth especially in the industrial sector in order to achieve vision 2020. The rapid industrialization process has caused increment in the energy demand, which simultaneously increases carbon dioxide (CO 2 ) emissions. Energy efficient technologies are strongly needed for reducing the energy requirement and to avoid the depleting of energy resources. This project focused on the application of integrated resource planning (IRP) in industrial sector using Combined Heat and Power (CHP), as a strategy for Demand Side Management (DSM). This approach is another way for meeting near and future energy requirement in Malaysia's industrial sector. Two scenarios which are Business As Usual (BAU) and CHP were developed using End Use Model EUM), to forecast the energy demand and CO 2 emission in Malaysia's industries. The effectiveness of the proposed method is then simulated using Long Range Energy Alternative Planning System (LEAP) software and Comparative Model for Projects of Engineering Economics and Energy Environmental Development (COMPEED) analysis. Evaluations were based on the potential of energy saving and CO 2 reduction. Scope of research was limited to pulp and paper industrial sub sector. The research data were extracted from Energy Audit Reports conducted by Malaysia Energy Center (PTM). An engineering calculation was demonstrated. Two designs of CHP applications for the pulp and paper industrial sector are according to heating and electricity sizing. It was found that the most energy efficient and CO 2 reduction for Malaysia's industrial sector is the CHP based on heating requirement. The method was found to be able of save fuel and GHG emission compared to the reference case. (author)

The impact of the EU ETS on the sectoral innovation system for power generation technologies - Findings for Germany

Rogge, Karoline S.; Hoffmann, Volker H.

2010-01-01

This paper provides an overview of early changes in the sectoral innovation system for power generation technologies which have been triggered by the European Emission Trading System (EU ETS). Based on a broad definition of the sector, our research analyses the impact of the EU ETS on the four building blocks 'knowledge and technologies', 'actors and networks', 'institutions', and 'demand' by combining two streams of literature, namely systems of innovation and environmental economics. Our analysis for Germany is based on 42 exploratory interviews with experts in the field of the EU ETS, the power sector, and technological innovation. We find that the EU ETS mainly affects the rate and direction of technological change of power generation technologies within the large-scale, coal-based power generation technological regime, to which carbon capture technologies are added as a new technological trajectory. While this impact can be interpreted as the defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO 2 culture and routines may prepare the ground for the transition to a low-carbon sectoral innovation system for power generation technologies.

System Dynamics Modelling of the Power Sector in Mauritius

Directory of Open Access Journals (Sweden)

Deenapanray Prakash N. K.

2015-12-01

Full Text Available A system dynamics model has been developed for the power sector of Mauritius, which captures a range of complex interactions between the economic, social and environmental aspects of the national economy, with deeper emphasis on the role of energy in these interactions. The model has been validated by replicating the historical trends of key development indicators, and its results were compared to the projections of the national utility company. The validation process shows that the model provides a faithful representation of the actual electricity sector of Mauritius, and can be easily adapted to the use of different assumptions. This paper describes the main characteristics of the model and its results as compared to electricity demand projections carried out by the Central Electricity Board to 2022. The results suggest that further analysis could be done to test alternative low carbon investment scenarios.

Chinese FDI and psychic distance perceptions on regulations in the German renewable energy sector

International Nuclear Information System (INIS)

Vaccarini, Katiuscia; Lattemann, Christoph; Spigarelli, Francesca; Tavoletti, Ernesto

2017-01-01

Countries vary in dimensions such as culture, language, business practices, policy-making, regulations, etc. Research shows that distances between countries concerning these dimensions affect foreign direct investment (FDI) flows. The higher the distances, the higher the difficulties for businesses, as managers’ decision-making is based on their perception of those distances. This paper analyzes the perception of distances between China and Germany by surveying Chinese managers who invested in Germany in the renewable energy (RE) sector, using Child et al.’s (2009) measure of psychic distance (PD) as a guide. The RE sector is young and highly dynamic, and the dimensions of PD are constantly changing. Mismatches in the perception of PD ex ante and ex post the decision to engage in FDI may lead to possible FDI failure. We use a five-company multiple case study to analyze if Chinese managers perceive distances in various dimensions, particularly regulation-based, and if there is a mismatch of perceptions between the pre-market and post-market entry period to investigate if managers’ perceptions change over time. Our findings lead to recommendations for practitioners and international business scholars, and policy making in the RE sector, by showing that operationalizing the PD construct should be complemented by dynamic analysis. - Highlights: • Chinese managers investing in Germany cope with distances on various dimensions • Decision-making is based on managers’ perception of those distances • This is particularly true for the RE sector and the relative regulation-based dimensions • “Prior experience” is a moderating variable and impacts managers’ perceptions. • Literature gap: perceptions vary over time and learning effects are detected.

Dall Anese, Emiliano; Guggilam, Swaroop S.; Simonetto, Andrea; Chen, Yu Christine; Dhople, Sairaj V.

2018-03-01

This paper develops a real-time algorithmic framework for aggregations of distributed energy resources (DERs) in distribution networks to provide regulation services in response to transmission-level requests. Leveraging online primal-dual-type methods for time-varying optimization problems and suitable linearizations of the nonlinear AC power-flow equations, we believe this work establishes the system-theoretic foundation to realize the vision of distribution-level virtual power plants. The optimization framework controls the output powers of dispatchable DERs such that, in aggregate, they respond to automatic-generation-control and/or regulation-services commands. This is achieved while concurrently regulating voltages within the feeder and maximizing customers' and utility's performance objectives. Convergence and tracking capabilities are analytically established under suitable modeling assumptions. Simulations are provided to validate the proposed approach.

CO{sub 2} abatement policies in the power sector under an oligopolistic gas market

Energy Technology Data Exchange (ETDEWEB)

Hecking, Harald

2014-09-15

The paper at hand examines the power system costs when a coal tax or a fixed bonus for renewables is combined with CO{sub 2} emissions trading. It explicitly accounts for the interaction between the power and the gas market and identifies three cost effects: First, a tax and a subsidy both cause deviations from the cost-efficient power market equilibrium. Second, these policies also impact the power sector's gas demand function as well as the gas market equilibrium and therefore have a feedback effect on power generation quantities indirectly via the gas price. Thirdly, by altering gas prices, a tax or a subsidy also indirectly affects the total costs of gas purchase by the power sector. However, the direction of the change in the gas price, and therefore the overall effect on power system costs, remains ambiguous. In a numerical analysis of the European power and gas market, I find using a simulation model integrating both markets that a coal tax affects gas prices ambiguously whereas a fixed bonus for renewables decreases gas prices. Furthermore, a coal tax increases power system costs, whereas a fixed bonus can decrease these costs because of the negative effect on the gas price.

Modelling of atmospheric transport of heavy metals emitted from Polish power sector. Many studies have been conducted to investigate the atmospheric heavy metals contamination and its deposition to ecosystems. The increasing attention to mercury pollution has been mainly driven by the growing evidence of its negative impacts on wildlife, ecosystems and particularly human health. Lead and cadmium are also toxics which are being emitted into the atmosphere by anthropogenic as well as natural sources. The harmful influence of these three heavy metals was underlined in the Aarhus Protocol on Heavy Metals of 1998. The Parties of this protocol (including Poland) are obligated to reduce emissions, observe the transport and the amounts of lead, mercury and cadmium in the environment. Poland is one of the biggest emitter of mercury, lead and cadmium in Europe mainly due to emission from coal combustion processes. Therefore in Poland, research efforts to study the heavy metals emission, atmospheric transport, concentration and deposition are extremely important. The objectives of this work were twofold: - The practical objective was to develop and run a model to represent the atmospheric dispersion of mercury and to implement it in the air quality modelling platform Polyphemus.- The scientific objective was to perform heavy metals dispersion studies over Europe and detailed studies of the impact of the polish power sector on the air quality regarding mercury, cadmium and lead. To meet the declared aim, a new mercury chemical model was implemented into the Polyphemus air quality system. The scientific literature was reviewed regarding mercury chemistry and mercury chemical models. It can be concluded that the chemistry of mercury is still not well known. The models also differ in the way of calculating the dry and wet deposition of mercury. The elemental gaseous mercury ambient concentrations are evenly distributed, on the contrary, high variations in the spatial gradients of

Highlights: • Pollutant surcharge is considered in Energy Conservation Supply Curve. • Intake Fraction method is incorporated into Energy Conservation Supply Curve. • Health benefits contribute 97% of co-benefits of energy efficiency improvement. - Abstract: The coal-fired power sector is one of the major contributors to environmental problems and has great potential of air pollution abatement. This study employs Energy Conservation Supply Curves (ECSCs) combined with pollutant surcharge and health benefits to evaluate the environmental co-benefits of energy efficiency improvement in the coal-fired power sector. Health benefits and the pollution surcharge are considered as the environmental co-benefits that reduce costs of conserved energy (CCEs) in ECSCs. The health benefits of energy efficiency improvement are quantified using Intake Fraction method, while the pollutant surcharge is calculated based on the regulation. Three scenarios including a Business As Usual (BAU) scenario, an Energy Efficiency Improvement (EEI) scenario, and an Upgrading Standards and Incentive (USI) scenario is considered in a case study for Henan Province of China. Our results show that costs of conserved energy (CCEs) are reduced by 0.56 and 0.29 USD/GJ under the EEI and USI scenarios due to health benefits and pollutant surcharge reductions related to energy efficient technologies, respectively. In particular, health benefits account for 97% of the reductions in CCEs, while the pollutant surcharge only contributes 3%. Under the EEI and USI scenarios, in 2020, energy efficiency improvement reduces energy consumption in Henan’s coal-fired power sector by 3.3% and 3.5% compared with the BAU scenario, respectively. The EEI and USI scenarios indicates that health benefits of 1.5 × 10"9 and 2.4 × 10"9 USD are gained and the reductions of pollutant surcharges of 197 and 226 million USD are realized in 2020, respectively.

Evaluating the CO 2 emissions reduction potential and cost of power sector re-dispatch

Energy Technology Data Exchange (ETDEWEB)

Steinberg, Daniel C.; Bielen, David A.; Townsend, Aaron

2018-01-01

Prior studies of the U.S. electricity sector have recognized the potential to reduce carbon dioxide (CO2) emissions by substituting generation from coal-fired units with generation from under-utilized and lower-emitting natural gas-fired units; in fact, this type of 're-dispatch' was invoked as one of the three building blocks used to set the emissions targets under the Environmental Protection Agency's Clean Power Plan. Despite the existence of surplus natural gas capacity in the U.S., power system operational constraints not often considered in power sector policy analyses, such as transmission congestion, generator ramping constraints, minimum generation constraints, planned and unplanned generator outages, and ancillary service requirements, could limit the potential and increase the cost of coal-to-gas re-dispatch. Using a highly detailed power system unit commitment and dispatch model, we estimate the maximum potential for re-dispatch in the Eastern Interconnection, which accounts for the majority of coal capacity and generation in the U.S. Under our reference assumptions, we find that maximizing coal-to-gas re-dispatch yields emissions reductions of 230 million metric tons (Mt), or 13% of power sector emissions in the Eastern Interconnection, with a corresponding average abatement cost of $15-$44 per metric ton of CO2, depending on the assumed supply elasticity of natural gas.

Work place regulations - effects on power station construction

The paper describes that the Workplace Order and Workplace Regulations cannot be applied in every area of a conventional power station or the conventional sections of nuclear power stations. In any case extensive regulations already exist for the hot regions of nuclear power stations. A proposal is made as to which areas of power stations should be developed in accordance with the Workplace Order and the Workplace Regulations and which areas are not deemed to be 'Workplaces'. This is illustrated with the aid of typical examples. (orig.) [de

Economic and institutional dynamics of electricity markets deregulation: the interaction between sectoral regulation and antitrust policy

International Nuclear Information System (INIS)

Fontanel, B.

2009-01-01

The purpose of this study is to define regulatory intervention as a part of a global monitoring procedure allowing the definition and adaptation of market structures and rules, given the observed behavior of market participants. Nevertheless, the possible inefficiency in its (decisional) coordination with competition authorities implies further analysis. We thus adopt a comparative methodology based on the studying PJM and NETA wholesale markets. This analysis enables us to stress two possible 'models' in the distribution and coordination of monitoring powers. The first one privileges a strong 'informational coordination' between the sectoral regulator and the Transmission System Operator. By contrast, the second model is characterized by a constrained informational coordination, leading to a greater 'decisional convergence' between regulatory intervention and antitrust policy. Lastly, we put these conclusions into perspective with the specific issue of the achievement of an efficient and integrated European market for electricity. In particular, we stress the need for a single regulatory agency, which should be given autonomous decisional powers in the adoption of regional markets reform initiatives (author)

This paper provides an overview of early changes in the sectoral innovation system for power generation technologies which have been triggered by the European Emission Trading Scheme (EU ETS). Based on a broad definition of the sector, our research analyses the impact of the EU ETS on the four building blocks 'knowledge and technologies', 'actors and networks', 'institutions' and 'demand' by combining two streams of literature, namely systems of innovation and environmental economics. Our analysis is based on 42 exploratory inter-views with German and European experts in the field of the EU ETS, the power sector and technological innovation. We find that the EU ETS mainly affects the rate and direction of the technological change of power generation technologies within the large-scale, coal-based power generation technological regime to which carbon capture technologies are added as a new technological trajectory. While this impact can be interpreted as defensive behaviour of incumbents, the observed changes should not be underestimated. We argue that the EU ETS' impact on corporate CO2 culture and routines may prepare the ground for the transition to a low carbon sectoral innovation system for power generation technologies. (orig.)

Modelling of hydro and wind power in the regulation market

Kiviluoma, J.; Holttinen, H.; Meibom, P.

2006-01-01

The amount of required regulation capacity in the power system is affected by the wind power prediction errors. A model has been developed which can evaluate the monetary effects of prediction errors. The model can be used to evaluate (1) the regulation costs of wind power, (2) regulation market prices including effects related to the participation of power producers in the regulating power market, (3) value of accurate wind forecasts and (4) the effect of decreasing the length of the spot market clearance. This article discusses the problems related to developing a realistic model of the regulating power market including the interaction between the spot market and the regulating power market. There are several issues that make things complicated. (1) How to calculate the minimum amount of needed secondary (minute) reserves. Traditionally the Nordic TSOs have used an N-1 criteria in each country to determine the required amounts of positive secondary reserve, but as installed wind power capacity grows, it will become relevant to include the wind power prediction errors in the estimation of secondary reserves. (2) Consumption forecast errors and plant outages also contribute to activation of regulating power and should have stochastic input series besides wind power. (3) Risk premiums and transaction costs in the regulating power market are difficult to estimate as well as the effects of the possible use of market power. This is especially true in the Nordic system with the high share of hydro power, since the water value and hydrological limitations make things more complex than in a thermal system. (4) The available regulation capacity is not necessarily equal to the truly available capacity. All producers don't participate in the regulation market although in principle they could. (orig.)

Pollution from the electric power sector in Japan and efficient pollution reduction

Under the scheme of the Kyoto Protocol, there are plans for the efficient reduction of carbon dioxide emissions. In the electric power sector, nuclear power generation, which emits no carbon dioxide in the process of generating electricity, has come under scrutiny. However, this energy produces a new environmental issue: the disposal of radioactive waste. First, we derive shadow prices of carbon dioxide and low-level waste as marginal abatement costs in the case of the electric power sector in Japan, employing a directional output distance function. It is found that the shadow prices are US$39 per tonne for carbon dioxide and US$1531 per liter for low-level waste. Secondly, we calculate the indirect Morishima elasticity between carbon dioxide and low-level waste in order to identify their substitutability, and it is found that the substitution of low-level waste for carbon dioxide is easier than the reverse. This result suggests that, with the amount of generated electricity fixed, carbon dioxide can be substituted more easily by low-level waste when the relative price of carbon dioxide increases, for example, as a result of implementation of a carbon dioxide tax or an emissions trading system.

Photovoltaic power in France, a declining sector

Boulanger, V.

2012-01-01

Figures from 2011 show an exceptional year in terms of grid connection and a poor year for business because the moratory on photovoltaic power decided end 2010 gave its full effect. The grid connections realized in 2011 resulted from installations decided before the moratory. The situation shows some inconsistencies: the household sector was not concerned by the moratory and nevertheless the drop of sales was sharp and even if the purchase price of the photovoltaic electricity was reduced from 0.58 to 0.35 euro/kWh it stays high when compared to 0.18 euro/kWh in Germany or 0.20 euro/kWh in Italy. The depressed nature of the market seems to go on in 2012. (A.C.)

Nonlinear integrated resource strategic planning model and case study in China's power sector planning

International Nuclear Information System (INIS)

Yuan, Jiahai; Xu, Yan; Kang, Junjie; Zhang, Xingping; Hu, Zheng

2014-01-01

In this paper we expand the IRSP (integrated resource strategic planning) model by including the external cost of TPPs (traditional power plants) and popularization cost of EPPs (efficiency power plants) with nonlinear functions. Case studies for power planning in China during 2011–2021 are conducted to show the efficacy of the model. Scenarios are compiled to compare the pathways of power planning under different policies. Results show that: 1) wind power will become competitive with technical learning, but its installation is undesirable when the external cost of coal power is not internalized; 2) the existence of popularization cost will hinder EPPs' (efficiency power plants) deployment and pure market mechanism is not enough to deliver EPPs at socially desirable scale; 3) imposition of progressive emission tax on coal power at an average of 0.15–0.20 RMB/KWh can remedy the market distortion and promote the development of wind power by a significant margin; 4) nuclear power will grow stably when its external cost is set no more than 0.187 RMB per KWh, or 87% of its internal cost. The proposed model can serve as a useful tool for decision support in the process of power planning and policy formulation for national government. - Highlights: • Improve IRSP model by adding nonlinear external and popularization cost. • The model is used to conduct China's power sector planning in 2011–2021. • Simulate the impacts of alternative energy policies on planning results. • The model can be used for joint power sector planning and policy design

Interconnection to the provincial power grid was also reviewed with reference to the risk faced by the promoters of a project in terms of project design, construction, financing, production and maintenance. The risks faced by Hydro-Quebec were also discussed along with risk allocations between the private and public sectors. tabs., figs

Environmental consequences of electricity sector reforms

International Nuclear Information System (INIS)

Wohlgemuth, N.

1999-01-01

Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

Nuclear power in competitive electricity markets

International Nuclear Information System (INIS)

2000-01-01

Economic deregulation in the power sector raises new challenges for the prospects of nuclear power. A key issue is to assess whether nuclear power can be competitive in a de-regulated electricity market. Other important considerations include safety, nuclear liability and insurance, the nuclear power infrastructure, and health and environmental protection. This study, conducted by a group of experts from twelve OECD Member countries and three international organisations, provides a review and analysis of these issues, as related to both existing and future nuclear power plants. It will be of particular interest to energy analysts, as well as to policy makers in the nuclear and government sectors. (author)

Timing-based business models for flexibility creation in the electric power sector

Helms, Thorsten; Loock, Moritz; Bohnsack, René

2016-01-01

Energy policies in many countries push for an increase in the generation of wind and solar power. Along these developments, the balance between supply and demand becomes more challenging as the generation of wind and solar power is volatile, and flexibility of supply and demand becomes valuable. As a consequence, companies in the electric power sector develop new business models that create flexibility through activities of timing supply and demand. Based on an extensive qualitative analysis of interviews and industry research in the energy industry, the paper at hand explores the role of timing-based business models in the power sector and sheds light on the mechanisms of flexibility creation through timing. In particular we distill four ideal-type business models of flexibility creation with timing and reveal how they can be classified along two dimensions, namely costs of multiplicity and intervention costs. We put forward that these business models offer ‘coupled services’, combining resource-centered and service-centered perspectives. This complementary character has important implications for energy policy. - Highlights: •Explores timing-based business models providing flexibility in the energy industry. •Timing-based business models can be classified on two dimensions. •Timing-based business models offer ‘coupled services’. • ‘Coupled services’ couple timing as a service with supply- or demand side valuables. •Policy and managerial implications for energy market design.

This paper is based on the Brazilian electric sector to outline parallels for introduction of hydrogen as energetic vector in Brazilian matrix. For this purpose it was achieved an analysis of regulation theory, of electric sector reorganization, the new model of energy trade and the NOS role. In face of this analysis, hydrogen regulation may be established through a mix of four models: tariff model by return tax; tariff by marginal cost; regulation by performance and price cap. This new industrial sector should start vertical and with its maturity become non vertical as electric sector after its reorganization. Regarding the market, advanced purchase of hydrogen should be established enabling the reduction of incertitude in trade as well as reduction of implantation costs. NOS should pursue electric energy generation from hydrogen as this may carry impacts in transmission networks as well as in distribution network depending on how hydrogen was generated, whether in large scale or for local consumption supply.

The construction and legitimation of workplace bullying in the public sector: insight into power dynamics and organisational failures in health and social care.

Science.gov (United States)

Hutchinson, Marie; Jackson, Debra

2015-03-01

Health-care and public sector institutions are high-risk settings for workplace bullying. Despite growing acknowledgement of the scale and consequence of this pervasive problem, there has been little critical examination of the institutional power dynamics that enable bullying. In the aftermath of large-scale failures in care standards in public sector healthcare institutions, which were characterised by managerial bullying, attention to the nexus between bullying, power and institutional failures is warranted. In this study, employing Foucault's framework of power, we illuminate bullying as a feature of structures of power and knowledge in public sector institutions. Our analysis draws upon the experiences of a large sample (n = 3345) of workers in Australian public sector agencies - the type with which most nurses in the public setting will be familiar. In foregrounding these power dynamics, we provide further insight into how cultures that are antithetical to institutional missions can arise and seek to broaden the debate on the dynamics of care failures within public sector institutions. Understanding the practices of power in public sector institutions, particularly in the context of ongoing reform, has important implications for nursing. © 2014 John Wiley & Sons Ltd.

The work activity developed on board is of great importance in our nearby environment, and it has a series of peculiarities that determine the service rendering of sea workers. On the other hand, work at sea is developed on an international basis. Nowadays such work becomes a completely globalised industrial sector in relation to the elements that make up the ship's operation, including manpower. For that reason several relevant international organisations have paid attention to this industrial sector and have adopted a broad regulation on this matter. In the case of the European Union, the Community procedure emphasises enormous interest in providing specific and comprehensive training to seafarers, as well as in regulating working time on board with the aim of minimising the safety problems caused by fatigue. In the present article a schematic presentation of regulations on workers' health and occupational safety protection derived from the European Union, the International Maritime Organisation, and the International Labour Organisation has been done. Also it shows what parts of these regulations are not applicable to the work on board, and it reveals how the workers of fishing and maritime transport sectors are under-protected with regard to the guarantee of their health and occupational safety compared to workers in other sectors.

From welfare states to welfare sectors: Explaining sectoral differences in occupational pensions with economic and political power of employees.

Science.gov (United States)

Wiß, Tobias

2015-12-01

Studies analysing welfare have previously focused on countries as units. In the course of pension cuts and the increasing importance of occupational welfare, our traditional understanding of a homogeneous welfare state is being challenged. In this article, I distinguish between both economic individual power (employee skills) and political collective power (trade unions), and their relation with different occupational pensions. A combined analysis by both factors is not common, where employee skills and power resources are traditionally treated as separate, rival explanations of public welfare. Combining the 'method of difference' with the 'method of agreement', the article first presents the within-country variety of occupational pensions in Germany, Italy, the United Kingdom and Denmark. Occupational pensions in the same economic sectors across countries are then used as the units of analysis in order to illustrate the plausible determinants of economic individual power and political collective power.

Fuzzy Controller for a Voltage-Regulated Solar-Powered MPPT System for Hybrid Power System Applications

2015-04-01

Full Text Available This paper presents the design of a fuzzy-logic-based voltage-regulated solar power maximum power point tracking (MPPT system for applications involving hybrid power systems. The system contains a solar power system and battery as the primary and secondary power sources, respectively. The solar system alone supplies power to the electric motor and maintains the output voltage at a predetermined level when it has sufficient power. When the solar power is insufficient, the solar system is operated at its maximum power point (MPP and the battery is engaged to compensate for the insufficiency. First, a variant of the incremental conductance MPP condition was established. Under the MPP condition, the voltage-regulated MPPT system was formulated as a feedback control system, where the MPP condition and voltage regulation requirements were used as the system inputs. Next, a fuzzy controller was developed to perform the voltage-regulated MPPT function for the hybrid power system. A simulation model based on Matrix laboratory (MATLAB/SIMULINK (a block diagram environment for multi-domain simulation and model-based design and a piecewise linear electric circuit simulation (PLECS tool for controlling the dc motor velocity was developed to verify the voltage-regulated solar power MPPT system.

Design of a real time market for regulating power. FlexPower WP1 - Report 3

Bang, C.; Fock, F.; Togeby, M.

2011-12-15

The FlexPower project investigates the possibility of using broadcasted dynamic electricity prices as a simple and low cost means to activating a large number of flexible small-scale power units. The aim is to provide regulating power via an aggregated response from the numerous units on a volunteer basis. The power units could for example be electrical heating and cooling units, electrical vehicles, industrial demand and micro generation. Each power unit can have its own local controller and individual business model and objective function. The optimisation of the local controls may require forecasts of the services requested by the customer (such as heat for a house or charging power for an electrical vehicle) - in terms of quantity, timing and flexibility - and forecasts of the electricity prices. Based on international 'real-time' power market experiences, new dynamic FlexPower market mechanisms to perform regulating power are designed and tested via simulations, under laboratory conditions and in the field. A dedicated simulation tool is developed for this purpose. The FlexPower regulation can never be perfect, but is expected to be able to meet some of the present and future growing demand for regulating power. As a starting point, a 5-minute power price signal, based on the actual regulation power prices, is tested. WP1 addresses the following question: 1) How could a system with a one-way price be designed? How can the FlexPower mechanism be integrated into the present electricity market, including the market for regulating power? This report describes the FlexPower concept, and gives one suggestion as to how this new market could work. How this will affect the different stakeholders is discussed, and risks and opportunities in the new market are presented. (LN)

Environmental regulation and competitiveness: Empirical evidence on the Porter Hypothesis from European manufacturing sectors

Rubashkina, Yana; Galeotti, Marzio; Verdolini, Elena

2015-01-01

This paper investigates the “weak” and “strong” versions of Porter Hypothesis (PH) focusing on the manufacturing sectors of 17 European countries between 1997 and 2009. The hypothesis that well-crafted and well-enforced regulation would benefit both the environment and the firm was originally proposed by Porter (1991) and Porter and van der Linde (1995). To date, the literature has analyzed the impact of environmental regulation on innovation and on productivity mostly in separate analyses and focusing on the USA. The few existing contributions on Europe study the effect of environmental regulation either on green innovation or on performance indicators such as exports. We instead look at overall innovation and productivity impacts. First, focusing on overall innovative activity allows us to account for potential opportunity costs of induced innovations. Second, productivity impacts are arguably the most relevant indicators for the “strong” PH. As a proxy of environmental policy stringency we use pollution abatement and control expenditures (PACE), one of the few sectoral level indicators available. We remedy upon its main drawback, namely potential endogeneity, by adopting an instrumental variable estimation approach. We find evidence of a positive impact of environmental regulation on the output of innovation activity, as proxied by patents, thus providing support in favor of the “weak” PH. This result is in line with most of the literature. On the other front, we find no evidence in favor of the “strong” PH, as productivity appears to be unaffected by the degree of pollution control and abatement efforts. -- Highlights: •Weak and strong Porter Hypothesis. •Panel of manufacturing sectors of 17 European countries between 1997 and 2009. •Look at overall innovation and productivity impacts. •Pollution abatement & control expenditures proxy of environmental policy stringency. •Account for potential endogeneity of PACE by adopting

Full Text Available The scandals that have tarnished the reputation of Wall Street and in Italy have damaged those who have invested their savings in Parmalat or Cirio corporate bonds or in Argentinean Government securities justify revisiting the objectives to be achieved by regulation and supervision of the financial sector. Stability is still regarded as paramount for banking, to be secured through an appropriate capital cushion, extensive supervisory arrangements, and market discipline, as agreed by Basel 2. Other financial intermediaries need to conduct their business with great transparency, openness and respect of the rules. However, an ever expanding and innovative financial sector, the blurring of traditional segmentations and globalisation make the task of regulating and supervising the financial sector more difficult and challenging, thus requiring new frameworks, for instance a single agency, in various jurisdictions and more international co-ordination and co-operation among regulating and supervising agencies. Up to now, the approach followed by the latter has been microeconomic, but the growing financial instability and the greater relevance of systemic risk may ask for a macroeconomic management of prudential regulation and supervision, thus complementing monetary policy in securing financial stability.

The model's treatment of the norm cost is evaluated, especially the effect analyses carried out by a so called Data Envelopment Analysis model. It is argued that there may exist an age lopsidedness in the data set, and that this should and can be corrected in the effect analyses. The adjustment is proposed corrected for by introducing an age parameter in the data set. Analyses of how the calibration effects in the regulation model affect the business' total income frame, as well as each network company's income frame have been made. It is argued that the calibration, the way it is presented, is not working according to its intention, and should be adjusted in order to provide the sector with the rate of reference in return (ml)

Does the regulation of the insurance industry have a pernicious effect on innovation by the sector in South Africa?

Directory of Open Access Journals (Sweden)

2015-07-01

Full Text Available Financial regulation could be a double edged sword in that despite its major thrust being that to secure the financial sector and bring about financial stability; it might have the unintended consequence of stifling innovation by the sector. We investigate the nexus between financial regulation and innovation by specifically focusing on the insurance industry in South Africa. We demonstrate that there are plethora pieces of legislation that govern the insurance industry in South Africa. As such this has driven the cost of compliance to unsustainable levels thereby curtailing the spending by companies on innovation. We thus would like to caution the policy makers’ that this “heavy-touch” regulatory mode is having a pernicious effect on research and development by the insurance sector. As such we encourage them to embrace the “light-touch” regulatory mode whereby self-regulation and moral suasion are other avenues to be considered.

Gas-to-power market and investment incentive for enhancing generation capacity: An analysis of Ghana's electricity sector

International Nuclear Information System (INIS)

Fritsch, Jorik; Poudineh, Rahmatallah

2016-01-01

Ghana's electricity generation capacity is currently insufficient to meet demand, making power outages and load shedding common. The resulting impact is potentially devastating for the country's growth prospects. Traditionally, lack of an affordable and reliable fuel supply for power generation, coupled with ineffective institutions and an unfavourable investment climate, have resulted in Ghana's electricity sector performing poorly. In light of the 2007 discovery of natural gas reserves in Ghanaian waters, this paper examines whether domestic gas could advance the performance of the electricity sector, and if so, how. The results of our analysis show that utilization of gas reserves in Ghana's gas-to-power market is an economically superior strategy compared to an export-oriented utilization scheme. The lack of an effective regulatory framework for investment, skill shortages, and an inefficient electricity pricing structure continue to be the main constraining factors. Our analysis also considers possible approaches to modification of the electricity tariff in order to send the right signal to potential investors in generation capacity, without compromising the affordability of power supply. - Highlights: •We examine if domestic gas can improve the Ghanaian electricity sector performance. •We compare domestic gas-to-power market utilisation versus gas export. •It shows that gas-to-power market is more economical compared to gas export. •Ineffective investment regime, skill shortage and inefficient tariffs are barriers.

A blocked takeover in the Polish power sector: A model-based analysis

International Nuclear Information System (INIS)

Kamiński, Jacek

2014-01-01

As the President of the Office of Competition and Consumer Protection refused to approve a government initiated takeover in the Polish power sector and the Court of Competition and Consumer Protection did not make a ruling on that case, the takeover was finally prohibited. In this context, the main aim of this paper is to carry out a quantitative analysis of the impact of the takeover in question on electricity prices and quantities, consumer and producer surpluses, dead weight loss and emissions. The scope of the study covers the Polish power generation sector and the analysis was carried out for 2009. A game theory-based electricity market equilibrium model developed for Poland was applied. The model includes several country-specific conditions, such as a coal-based power generation fuel-mix, a large share of biomass co-combustion, etc. For the sake of clarity, only four scenarios are assumed. The paper concludes that the declared synergy savings did not compensate for the increase in dead weight loss and the transfer of surplus from consumers to producers caused by increased market power. - Highlights: • A takeover blocked by the President of the Office of Competition and Consumer Protection was analysed. • A game theory-based model of the Polish wholesale electricity market was applied. • The impact of the takeover on electricity prices and generation levels, surplus transfers and dead weight loss was estimated. • The results were compared with the declared synergy savings

Can developing countries benefit from innovative pricing in the power sector?

International Nuclear Information System (INIS)

Hill, L.J.

1991-01-01

This study explores electricity pricing as a demand-side management (DSM) strategy, looking to the developed country experience for insights into the types of approaches currently used, their effects, and the direction in which electricity pricing is headed. The discussion should be especially useful for electric utilities in developing countries that are exploring alternatives to capacity expansion to meet current and future electric power demand. For these electric utilities, demand-side options are especially important under today's conditions in which the capital cost of new generating capacity is increasing rapidly, international funds for expanding power sectors are not expected to be sufficient for meeting projected capacity needs and environmental concerns over fossil fuel emissions have raised new questions about constructing thermal power plants.

Issues in Energy Economics Led by Emerging Linkages between the Natural Gas and Power Sectors

International Nuclear Information System (INIS)

Platt, Jeremy B.

2007-01-01

Fuel prices in 2006 continued at record levels, with uranium continuing upward unabated and coal, SO 2 emission allowances, and natural gas all softening. This softening did not continue for natural gas, however, whose prices rose, fell and rose again, first following weather influences and, by the second quarter of 2007, continuing at high levels without any support from fundamentals. This article reviews these trends and describes the remarkable increases in fuel expenses for power generation. By the end of 2005, natural gas claimed 55% of annual power sector fuel expenses, even though it was used for only 19% of electric generation. Although natural gas is enormously important to the power sector, the sector also is an important driver of the natural gas market-growing to over 28% of the market even as total use has declined. The article proceeds to discuss globalization, natural gas price risk, and technology developments. Forces of globalization are poised to affect the energy markets in new ways-new in not being only about oil. Of particular interest in the growth of intermodal traffic and its a little-understood impacts on rail traffic patterns and transportation costs, and expected rapidly expanding LNG imports toward the end of the decade. Two aspects of natural gas price risk are discussed: how understanding the use of gas in the power sector helps define price ceilings and floors for natural gas, and how the recent increase in the natural gas production after years of record drilling could alter the supply-demand balance for the better. The article cautions, however, that escalation in natural gas finding and development costs is countering the more positive developments that emerged during 2006. Regarding technology, the exploitation of unconventional natural gas was one highlight. So too was the queuing up of coal-fired power plants for the post-2010 period, a phenomenon that has come under great pressure with many consequences including increased

The purpose of this paper is to present gas allocation plans developed for PETROBRAS Gas and Power Sector, considering failure to supply scenarios that could occur along gas supply network. Those scenarios, as well as the associated contingency plans, were identified and validated by an experienced team, composed by engineers and operators from different PETROBRAS sectors. The key issue of concern was the anticipation of possible undesired scenarios that could imply on contract shortfalls, the evaluation of possible maneuvers, taking into account best gas delivery allocation. Different software were used for the simulation of best gas supply allocation and for the verification of delivery pressure and conditions for final consumers. The ability of being capable of dealing with undesired or crisis scenarios, based on suitable anticipation levels, is, nowadays, a highly valuable attribute to be presented by competitive corporations, for best crisis management and prompt recovery response. Those plans are being used by Gas and Power Gas Operation Control Centre and as an input for reliability modeling of gas supply chain. (author)

The future structure surrounding fuel choice in power generation sector should be understood how to evaluate actual and potential merit and demerit both in economic and environmental aspects on nuclear power generation. That is i.e. nuclear can be understood as superior power source without GHGs and on the other hand, as unfavorable power source which might cause some critical dangers due to its hazardous radioactive nuclear waste. On this specific characteristic, this theme on fuel choice surrounding nuclear in power generation sector could be understood as a highly cultural problem as much as economic and political one. For instance, we can observe quite opposite direction with each other on nuclear power development in European countries like France and Finland on one hand and Germany and Sweden on the other hand. Looking at Asian countries, we also observe the very reality of high economic growth with rapid growth of electricity demand like China. What on earth, is it really possible without nuclear power source for such gigantic countries. I will develop my personal idea on nuclear power source based on Japanese experience towards successfully managing nuclear power technologies in the world, consisting of developing countries with growing economies and of advanced ones with rather matured nuclear technology under the pressure of environmentally restricted world order. My basic view point to discuss nuclear power problem has, conclusionally speaking, several aspects; The first one is in the relation with deregulation or liberalization of electricity market, which has been undergoing among such developed countries as OECD member countries i.e. USA, EU, Japan and other countries. Deregulation or liberalization of electricity market seems to be the inevitable process towards more matured market economy among developed countries group, and that process inevitably forces management of power companies towards more near sighted attitude if those companies are

The future of the grid includes distributed generation and smart grid technologies. Demand Side Management (DSM) systems will also be essential to achieve a high level of reliability and robustness in power systems. To do that, expanding the Advanced Metering Infrastructure (AMI) and Energy Management Systems (EMS) are necessary. The trend direction is towards the creation of energy resource hubs, such as the smart community concept. This paper presents a smart multiconverter system for residential/housing sector with a Hybrid Energy Storage System (HESS) consisting of supercapacitor and battery, and with local photovoltaic (PV) energy source integration. The device works as a distributed energy unit located in each house of the community, receiving active power set-points provided by a smart community EMS. This central EMS is responsible for managing the active energy flows between the electricity grid, renewable energy sources, storage equipment and loads existing in the community. The proposed multiconverter is responsible for complying with the reference active power set-points with proper power quality; guaranteeing that the local PV modules operate with a Maximum Power Point Tracking (MPPT) algorithm; and extending the lifetime of the battery thanks to a cooperative operation of the HESS. A simulation model has been developed in order to show the detailed operation of the system. Finally, a prototype of the multiconverter platform has been implemented and some experimental tests have been carried out to validate it.

1995-01-01

In this article, the author discusses the analysis of power sector system losses in both the countries which are similar in nature. The design and construction of major power plants, grid substations and transmission lines are constructed on the same pattern. The generation system loss under transmission must not exceed the limit and any loss above this limit could safely be taken as pilferage or theft of energy. The author is of the opinion that socio-economic conditions prevailing in both countries. The author is not in a position to analyse or comment on the causes of non-technical system loss in Pakistan, but he feels that some of the causes could also equally be applicable. (A.B.)

Full Text Available “Linking the power and transport sectors—Part 1” describes the general principle of “sector coupling” (SC, develops a working definition intended of the concept to be of utility to the international scientific community, contains a literature review that provides an overview of relevant scientific papers on this topic and conducts a rudimentary analysis of the linking of the power and transport sectors on a worldwide, EU and German level. The aim of this follow-on paper is to outline an approach to the modelling of SC. Therefore, a study of Germany as a case study was conducted. This study assumes a high share of renewable energy sources (RES contributing to the grid and significant proportion of fuel cell vehicles (FCVs in the year 2050, along with a dedicated hydrogen pipeline grid to meet hydrogen demand. To construct a model of this nature, the model environment “METIS” (models for energy transformation and integration systems we developed will be described in more detail in this paper. Within this framework, a detailed model of the power and transport sector in Germany will be presented in this paper and the rationale behind its assumptions described. Furthermore, an intensive result analysis for the power surplus, utilization of electrolysis, hydrogen pipeline and economic considerations has been conducted to show the potential outcomes of modelling SC. It is hoped that this will serve as a basis for researchers to apply this framework in future to models and analysis with an international focus.

1997-11-01

For reliable operation and component protection, of the 2 MW 30--120 MHz ICRF Amplifier System on DIII-D, it is desirable for the amplifier to respond to high VSWR conditions as rapidly as possible. This requires a rapid change in power which also means a rapid change in the high voltage power supply current demands. An analysis of the power supply's regulator dynamics was needed to verify its expected operation during such conditions. Based on this information it was found that a new regulator with a larger dynamic range and some anticipation capability would be required. This paper will discuss the system requirements, the as-delivered regulator performance, and the improved performance after installation of the new regulator system. It will also be shown how this improvement has made the amplifier perform at higher power levels more reliably

Nigeria's electric power sector reform: what should form the key objectives?

International Nuclear Information System (INIS)

Ikeme, J.; Ebohon, O.J.

2005-01-01

Nigeria's electric power sector requires substantial reform if the country's economic development and poverty alleviation program is to be realised. This understanding is behind the reform programme recently initiated by the Nigerian government with the goal of privatising the national electric power monopoly, NEPA. Currently, the country faces serious energy crisis due to declining electricity generation from domestic power plants which are basically dilapidated, obsolete, unreliable and in an appalling state of disrepair, reflecting the poor maintenance culture in the country and gross inefficiency of the public utility provider. Building on an analysis of the major shortcomings of the current electric power company, this paper presents the central issues that should form the key objectives of the proposed reform. This include corporatization of the electric power industry, increasing access and power delivery capacity, constraining the costs of the power industry and increasing efficiency and share of renewables in energy generation, as well as minimising environmental damage. We conclude with the observation that efforts at reform will not yield the desired result if the current end-user inefficiency is not constrained. As Nigeria implements its national utility privatisation programme, it is hoped that this review will benefit policy makers and emerging managers and providers of electricity service in the country

Federal tax credits for renewable energy (RE) have served as one of the primary financial incentives for RE deployment over the last two decades in the United States. In December 2015, the wind power production tax credit and solar investment tax credits were extended for five years as part of the Consolidated Appropriations Act of 2016. This report explores the impact that these tax credit extensions might have on future RE capacity deployment and power sector carbon dioxide (CO2) emissions. The analysis examines the impacts of the tax credit extensions under two distinct natural gas price futures as natural gas prices have been key factors in influencing the economic competitiveness of new RE development. The analysis finds that, in both natural gas price futures, RE tax credit extensions can spur RE capacity investments at least through the early 2020s and can help lower emissions from the U.S. electricity system. More specifically, the RE tax credit extensions are estimated to drive a net peak increase of 48-53 GW in installed RE capacity in the early 2020s -- longer term impacts are less certain. In the longer term after the tax credits ramp down, greater RE capacity is driven by a combination of assumed RE cost declines, rising fossil fuel prices, and other clean energy policies such as the Clean Power Plan. The tax credit extension-driven acceleration in RE capacity development can reduce fossil fuel-based generation and lower electric sector CO2 emissions. Cumulative emissions reductions over a 15-year period (spanning 2016-2030) as a result of the tax credit extensions are estimated to range from 540 to 1420 million metric tonnes CO2. These findings suggest that tax credit extensions can have a measurable impact on future RE deployment and electric sector CO2 emissions under a range of natural gas price futures.

Why (and how) to regulate power exchanges in the EU market integration context?

International Nuclear Information System (INIS)

Meeus, Leonardo

2011-01-01

The European Union (EU) market integration is leading to increasingly monopolistic electricity market infrastructures, which has opened a debate on the regulation of these so-called power exchanges. In this paper, we start by stating that there are two types of power exchanges in Europe, i.e. 'merchant' and 'cost-of-service regulated' power exchanges. We then discuss how regulation can be used to better align their incentives with the main power exchange tasks. We conclude that adopting the cost-of-service regulated model for all power exchanges in Europe could be counterproductive in the current context, but that regulation can help ensure that the benefits of the EU market integration materialize. Promising regulatory actions include tempering the reinforced market power of power exchanges, and quality-of-service regulation for the ongoing cooperation among power exchanges to organize trade across borders. - Research highlights: → Market integration is leading to increasingly monopolistic electricity market infrastructures. → Regulation can help tempering the market power of these so-called power exchanges in Europe. → Cost-of-service regulation for all power exchanges could however be counterproductive. → More promising is to subject cooperation among power exchanges to quality of service regulation.

This is done by investigating the consequences of choice of objective function in relation to the estimation of the power curve that is applied in the prognoses...... wind power production predicted will differ. In turn this will influence the operation and economics of the system. The consequences of this are illustrated by application to the integration of wind power in the Danish parts of the Nordpool area, using recent data. Using a regression analysis...

The effect of environmental regulation on firms' competitive performance: the case of the building & construction sector in some EU regions.

Testa, Francesco; Iraldo, Fabio; Frey, Marco

2011-09-01

There is a considerable debate on the effects of environmental regulation on competitive performance. Based on survey data, this paper analyzes the two main research questions, derived from literature, on the links between environmental regulation and competitiveness, by focusing on firms operating in the building and construction sector, i.e.: 1) whether environmental policy stringency affects the competitive performance of firms in the building and construction sector 2) and how a specific form of environmental regulation (direct regulation, economic instruments and soft instruments) affects this performance? By applying a regression analysis, we find that a more stringent environmental regulation, measured by inspection frequency, provides a positive impulse for increasing investments in advanced technological equipment and innovative products and on business performance. Moreover, a well-designed "direct regulation" appears to be the most effective policy instrument for prompting the positive impact of environmental policies on innovation and intangible performance while economic instruments do negatively affect business performance.

This study analyzes the key factors behind the CO 2 emissions from the power sector in fifteen selected countries in Asia and the Pacific using the Log-Mean Divisia Index method of decomposition. The roles of changes in economic output, electricity intensity of the economy, fuel intensity of power generation and generation structure are examined in the evolution of CO 2 emission from the power sector of the selected countries during 1980-2004. The study shows that the economic growth was the dominant factor behind the increase in CO 2 emission in ten of the selected countries (i.e., Australia, China, India, Japan, Malaysia, Pakistan, South Korea, Singapore, Thailand and Vietnam, while the increasing electricity intensity of the economy was the main factor in three countries (Bangladesh, Indonesia and Philippines). Structural changes in power generation were found to be the main contributor to changes in the CO 2 emission in the case of Sri Lanka and New Zealand.

Possible Power Estimation of Down-Regulated Offshore Wind Power Plants

DEFF Research Database (Denmark)

Gögmen, Tuhfe

The penetration of offshore wind power is continuously increasing in the Northern European grids. To assure safety in the operation of the power system, wind power plants are required to provide ancillary services, including reserve power attained through down-regulating the wind farm from its...... power plant. The developed procedure, the PossPOW algorithm, can also be used in the wind farm control as it yields a real-time wind farm power curve. The modern wind turbines have a possible power signal at the turbine level and the current state of the art is to aggregate those signals to achieve...... the wind farm scale production capacity. However the summation of these individual signals is simply an over-estimation for the wind power plant, due to reduced wake losses during curtailment. The determination of the possible power with the PossPOW algorithm works as follows: firstly the second...

Supply- and demand-side effects of power sector planning with demand-side management options and SO2 emission constraints

International Nuclear Information System (INIS)

Shrestha, R.M.; Marpaung, C.O.P.

2005-01-01

This paper examines the implications of SO 2 emission mitigation constraints in the power sector planning in Indonesia--a developing country--during 2003-2017 from a long term integrated resource planning perspective. A decomposition model is developed to assess the contributions of supply- and demand-side effects to the total changes in CO 2 , SO 2 and NO x emissions from the power sector due to constraints on SO 2 emissions. The results of the study show that both the supply- and demand-side effects would act towards the reduction of CO 2 , SO 2 and NO x emissions. However, the supply-side effect would play the dominant role in emission mitigations from the power sector in Indonesia. The average incremental SO 2 abatement cost would increase from US$ 970 to US$ 1271 per ton of SO 2 , while electricity price would increase by 2-18% if the annual SO 2 emission reduction target is increased from 10% to 25%

International Nuclear Information System (INIS)

Singh, Randhir; Sood, Yog Raj

2011-01-01

Restructuring has changed the traditional mission and mandates of power utilities in complex ways, and had large impacts on environmental, social, and political conditions for any particular country. At the same time, new regulatory approaches are being found for reducing environmental impacts in restructured power sectors. India has a vast supply of renewable energy resources, and it has one of the largest programs in the world for deploying renewable energy based products and systems. So this paper attempts to review the various policies and measures undertaken by Indian government for promotion of renewable energy. The aim of this paper is also to review the current policy mechanisms, especially investment- or generation-based price-driven and capacity-driven mechanisms, ranging from investment incentives for the development of renewable energy projects, feed-in tariffs, production tax incentives, tradable green certificates, and their effects upon the prospects of encouraging as well as expanding the development of renewable energy in Indian restructured power sector. This will make renewable more attractive in the Indian future electricity market. (author)

Why (and how) to regulate power exchanges in the EU market integration context?

The European Union (EU) market integration is leading to increasingly monopolistic electricity market infrastructures, which has opened a debate on the regulation of these so-called power exchanges. In this paper, we start by stating that there are two types of power exchanges in Europe, i.e. 'merchant' and 'cost-of-service regulated' power exchanges. We then discuss how regulation can be used to better align their incentives with the main power exchange tasks. We conclude that adopting the cost-of-service regulated model for all power exchanges in Europe could be counterproductive in the current context, but that regulation can help ensure that the benefits of the EU market integration materialize. Promising regulatory actions include tempering the reinforced market power of power exchanges, and quality-of-service regulation for the ongoing cooperation among power exchanges to organize trade across borders. - Research highlights: {yields} Market integration is leading to increasingly monopolistic electricity market infrastructures. {yields} Regulation can help tempering the market power of these so-called power exchanges in Europe. {yields} Cost-of-service regulation for all power exchanges could however be counterproductive. {yields} More promising is to subject cooperation among power exchanges to quality of service regulation.

Sijm, Jos; Neuhoff, Karsten; Yihsu Chen

2006-01-01

In order to cover their CO 2 emissions, power companies receive most of the required EU ETS allowances for free. In line with economic theory, these companies pass on the costs of these allowances in the price of electricity. This article analyses the implications of the EU ETS for the power sector, notably the impact of free allocation of CO 2 emission allowances on the price of electricity and the profitability of power generation. As well as some theoretical reflections, the article presents empirical and model estimates of CO 2 cost pass-through for Germany and The Netherlands, indicating that pass-through rates vary between 60 and 100% of CO 2 costs, depending on the carbon intensity of the marginal production unit and various other market- or technology-specific factors. As a result, power companies realize substantial windfall profits, as indicated by the empirical and model estimates presented in the article. (Author)

Because the gas and the electric power are not simple goods, the opening of their market needs a whole reflexion where the governments must be involved. To analyse this opening, this report presents in a first part the traditional organization of the gas and electric power sectors marked by the strong presence of the government and the end of this organization at the end of the years 1980. It details then the new regulation, the operators and the effects of the competition. In a last part it provides propositions for the institutional framework in France. (A.L.B.)

Electricity sector integration in West Africa

International Nuclear Information System (INIS)

Pineau, Pierre-Olivier

2008-01-01

Regional and global integration initiatives push for more electricity sector integration everywhere in the world, including West Africa. The creation of the West African Power Pool (WAPP) in 2000 and important investments under this new structure in 2006 are concrete actions that will result in a more integrated West African electricity sector. But will this integrated sector be more functional than the previous ones? Will the identified electricity sector problems be solved with the new power pool? This paper analyzes how power sector integration is presented by international institutions (the UN Economic Commission for Africa, World Energy Council and World Bank) and identifies three problematic issues with the current integration approach: lack of African ownership, unclear and conflicting reform objectives and uncertainty of integration outcomes

Open innovation in the power & energy sector: Bringing together government policies, companies’ interests, and academic essence

The Power and Energy (P&E) sector needs to respond to several challenges fostering investments in research and development. According to the Open Innovation (OI) paradigm, key stakeholders like utilities, vendors, laboratories, universities etc. should take advantage of external knowledge to improve their innovation performance. Several studies have demonstrated that firms adopting the OI paradigm are more likely to innovate. Despite the interest of P&E firms in enhancing their innovation capabilities, surprisingly few articles (usually case studies) described the implementation of the OI paradigm in P&E firms. This article fills the gap by identifying the key drivers that encourage a firm in the P&E sector to embrace the OI paradigm. The authors adopt a hybrid research approach collecting evidence from the literature and through a multiple case-study analysis involving seven British firms and universities operating in the P&E industry. As the drivers of OI have mutual influence, this article describes them with a fuzzy cognitive map. Finally, the authors identify appropriated policies to enhance the OI adoption and, consequently, the sustainability of innovation in the P&E sector. A salient research agenda closes the paper. - Highlights: • Stakeholders are increasingly adopting the Open Innovation (OI) paradigm. • OI can enhance firms and universities innovation performance. • Few studies analyzed the OI implementation in the Power and Energy (P&E) sector. • We identify the factors encouraging the adoption of the OI paradigm in the P&E sector. • We show benefits of OI obtained by P&E firms, universities, and associates in the UK.

Projects with large infrastructures, particularly those in the field of energy, provide a strong boost to certain industrial sectors in the country. In the case of Spain, the policy of direct management 'by components' of these projects - hydroelectric power plants, petrochemical plants, thermoelectric plants and nuclear power plants - adopted by the electric utility owners has furthered not only the local equipment manufacturing industry but also the engineering sector. At present, with full implementation of the Single Market in sight, it is particularly interesting for Spain to continue building up a powerful engineering sector, increasing its size and usefulness, and extending its traditional areas of action to other technologies, more on the lines of engineering and consulting firms in the USA than in the rest of Europe. The intention is to endow our equipment and construction companies with the skills necessary to enable them to compete with large European conglomerates in their respective sectors. The structure of these conglomerates usually contains engineering capabilities which are not habitual in our industry. Examples are given, showing how this model has been used to compete and win awards for important international projects. A specific analysis has been made of the position of Spanish engineering and industry in nuclear power generation projects in the former Soviet Union and East European countries, in which large investments are expected to be made.

The combined emissions and air quality impacts of electricity generation in the Texas grid and natural gas production in the Eagle Ford shale were estimated at various natural gas price points for the power sector. The increased use of natural gas in the power sector, in place of coal-fired power generation, drove reductions in average daily maximum 8 h ozone concentration of 0.6-1.3 ppb in northeastern Texas for a high ozone episode used in air quality planning. The associated increase in Eagle Ford upstream oil and gas production nitrogen oxide (NOx) emissions caused an estimated local increase, in south Texas, of 0.3-0.7 ppb in the same ozone metric. In addition, the potential ozone impacts of Eagle Ford emissions on nearby urban areas were estimated. On the basis of evidence from this work and a previous study on the Barnett shale, the combined ozone impact of increased natural gas development and use in the power sector is likely to vary regionally and must be analyzed on a case by case basis.

The paper aims to present the current status of the coal-fired power sector in Russia, the prospects for renovation activities based on Clean Coal Technologies (CCT) and two case studies on potential refurbishment projects. Data were collected for 180 thermoelectric units with capacity higher than 100 MWe and the renovation needs of the power sector, among the retrofitting, repowering and reconstruction options, were estimated through a multi-criteria analysis. The most attractive system to renovate a power plant between the Supercritical Combustion (SC) and the Fluidized Bed Combustion (FBC) technologies was evaluated. The application of each of the aforementioned technologies at the Kashirskaya and Shaturskaya power plants was studied and their replication potential in the Russian coal-fired power plant park was examined. Nowadays, the installed capacity of coal-fired power plants in the Russian Federation is 29.3 GWe, while they account for about 19% of the total electricity generation in the area. The low efficiency and especially the advanced age are the determinant factors for renovation applications at the Russian units. Even in the more conservative modernization scenario, over 30% of the thermoelectric units have to be repowered or reconstructed. Concrete proposals about the profitable and reliable operation of two Russian thermoelectric units with minimized environmental effects were elaborated. A new unit of 315 MWe with supercritical steam parameters and reburning for NO x abatement is envisaged to upgrade Unit 1 of Kashirskaya power station, while new Circulating Fluidized Bed (CFB) boilers of the same steam generation is the most promising renovation option for the boilers of Unit 1 in Shaturskaya power station

The effect of regulatory governance on efficiency of thermal power generation in India: A stochastic frontier analysis

International Nuclear Information System (INIS)

Ghosh, Ranjan; Kathuria, Vinish

2016-01-01

This paper investigates the impact of institutional quality – typified as regulatory governance – on the performance of thermal power plants in India. The Indian power sector was reformed in the early 1990s. However, reforms are effective only as much as the regulators are committed in ensuring that they are implemented. We hypothesize that higher the quality of regulation in a federal Indian state, higher is the efficiency of electric generation utilities. A translog stochastic frontier model is estimated using index of state-level independent regulation as one of the determinants of inefficiency. The dataset comprises a panel of 77 coal-based thermal power plants during the reform period covering over 70% of installed electricity generation capacity. The mean technical efficiency of 76.7% indicates there is wide scope for efficiency improvement in the sector. Results are robust to various model specifications and show that state-level regulators have positively impacted plant performance. Technical efficiency is sensitive to both unbundling of state utilities, and regulatory experience. The policy implication is that further reforms which empower independent regulators will have far reaching impacts on power sector performance. - Highlights: • The impact of regulatory governance on Indian generation efficiency is investigated. • Stochastic frontier analysis (SFA) on a panel dataset covering pre and post reform era. • Index of state-wise variation in regulation to explain inefficiency effects. • Results show improved but not very high technical efficiencies. • State-level regulation has positively impacted power plant performance.

Evaluation of lifecycle CO2 emissions from the Japanese electric power sector in the 21st century under various nuclear scenarios

The status and prospects of the development of Japanese nuclear power are controversial and uncertain. Many deem that nuclear power can play key roles in both supplying energy and abating CO 2 emissions; however, due to severe nuclear accidents, public acceptance of nuclear power in Japan has not been fully obtained. Moreover, deregulation and liberalization of the electricity market impose pressure on large Japanese electric power companies with regard to both the operation of nuclear power plants and the development of the nuclear fuel cycle. Long-term Japanese CO 2 reduction strategies up to 2100 are of environmental concern and are socially demanded under the circumstances described above. Taking these factors into account, we set the following two objectives for this study. One is to estimate lifecycle CO 2 (LCCO 2 ) emissions from Japanese nuclear power, and the other is to evaluate CO 2 emissions from the Japanese electric power sector in the 21st century by quantifying the relationship between LCCO 2 emissions and scenarios for the adoption of nuclear power. In the pursuit of the above objectives, we first create four scenarios of Japanese adoption of nuclear power, that range from nuclear power promotion to phase-out. Next, we formulate four scenarios describing the mix of the total electricity supply in Japan till the year 2100 corresponding to each of these nuclear power scenarios. CO 2 emissions from the electric power sector in Japan till the year 2100 are estimated by summing those generated by each respective electric power technology and LCCO 2 emission intensity. The LCCO 2 emission intensity of nuclear power for both light water reactors (LWR) and fast breeder reactors (FBR) includes the uranium fuel production chain, facility construction/operation/decommission, and spent fuel processing/disposal. From our investigations, we conclude that the promotion of nuclear power is clearly a strong option for reducing CO 2 emissions by the electric power

Constructing a sustainable power sector in China: current and future emissions of coal-fired power plants from 2010 to 2030

Science.gov (United States)

Tong, D.; Zhang, Q.

2017-12-01

As the largest energy infrastructure in China, power sector consumed more coal than any other sector and threatened air quality and greenhouse gas (GHG) abatement target. In this work, we assessed the evolution of coal-fired power plants in China during 2010-2030 and the evolution of associated emissions for the same period by using a unit-based emission projection model which integrated the historical power plants information, turnover of the future power plant fleet, and the evolution of end-of-pipe control technologies. We found that, driven by the stringent environmental legislation, SO2, NOx, and PM2.5 emissions from China's coal-fired power plants decreased by 49%, 45%, and 24% respectively during 2010-2015, comparing to 14% increase of coal consumption and 15% increase in CO2 emissions. We estimated that under current national energy development planning, coal consumption and CO2 emissions from coal-fired power plants will continue to increase until 2030, in which against the China's Intended Nationally Determined Contributions (INDCs) targets. Early retirement of old and low-efficient power plants will cumulatively reduce 2.2 Pg CO2 emissions from the baseline scenario during 2016-2030, but still could not curb CO2 emissions from the peak before 2030. Owing to the implementation of "near zero" emission control policy, we projected that emissions of air pollutants will significantly decrease during the same period under all scenarios, indicating the decoupling trends of air pollutants and CO2 emissions. Although with limited direct emission reduction benefits, increasing operating hours of power plants could avoid 236 GW of new power plants construction, which could indirectly reduce emissions embodied in the construction activity. Our results identified a more sustainable pathway for China's coal-fired power plants, which could reduce air pollutant emissions, improve the energy efficiency, and slow down the construction of new units. However, continuous

The report discusses the organization and behaviour of grid monopolies in the Norwegian power trade and relations to the socio-economic effectiveness. The main attention is laid on analyzing regulation mechanisms and measures leading to an efficient short-term operation and to the investment of optimum production capacity in a long run. Regarding the management, measures are discussed for increasing the efficiency of total power trade by evaluating the existing marketing function of Statnett. Some basic conditions are accounted concerning the regulation problem of grid monopolies with a particular attention to asymmetric information between the authority and the monopoly. In addition, forms of regulation and regulation mechanisms together with the incentive characteristics of these, are discussed. The existing profit regulation principles in relation to an alternative system design such as maximum price regulation combined with standard regulation, are evaluated. 16 refs., 7 figs

Adequate infrastructure is essential to a country's growth. It provides a foundation which enables the economy to function. Until recently, most governments provided the physical infrastructure of industry: transport, communications, and power systems. Today, the trend is for governments to regulate monopolies while taking maximum advantage of private sector investment, decision-making and management. The private sector is increasingly being recognized as having the capacity to operate infrastructure projects more efficiently. (author)

We utilized our previous studies analyzing the reforms affecting the health sector developed in the 1990s by financial groups to frame the strategies implemented by the pharmaceutical industry to regain market positions and to understand the challenges that regulatory agencies are confronting. We followed an analytical approach for analyzing the process generated by the disputes between the financial groups and the pharmaceutical corporations and the challenges created to governmental regulation. We analyzed primary and secondary sources using situational and discourse analyses. We introduced the concepts of biomedicalization and biopedagogy, which allowed us to analyze how medicalization was radicalized. In the 1990s, structural adjustment policies facilitated health reforms that allowed the entrance of multinational financial capital into publicly-financed and employer-based insurance. This model operated in contraposition to the interests of the medical industrial complex, which since the middle of the 1990s had developed silent reforms to regain authority in defining the health-ill-care model. These silent reforms radicalized the medicalization. Some reforms took place through deregulatory processes, such as allowing direct-to-consumer advertisements of prescription drugs in the United States. In other countries different strategies were facilitated by the lack of regulation of other media such as the internet. The pharmaceutical industry also has had a role in changing disease definitions, rebranding others, creating new ones, and pressuring for approval of treatments to be paid by public, employer, and private plans. In recent years in Brazil there has been a substantial increase in the number of judicial claims demanding that public administrations pay for new treatments. We found that the dispute for the hegemony of the health sector between financial and pharmaceutical companies has deeply transformed the sector. Patients converted into consumers are

The report discusses the organization and behaviour of grid monopolies in the Norwegian power trade and relations to the socio-economic effectiveness. The main attention is laid on analyzing regulation mechanisms and measures leading to an efficient short-term operation and to the investment of optimum production capacity in a long run. Regarding the management, measures are discussed for increasing the efficiency of total power trade by evaluating the existing marketing function of Statnett. Some basic conditions are accounted concerning the regulation problem of grid monopolies with a particular attention to asymmetric information between the authority and the monopoly. In addition, forms of regulation and regulation mechanisms together with the incentive characteristics of these, are discussed. The existing profit regulation principles in relation to an alternative system design such as maximum price regulation combined with standard regulation, are evaluated. 16 refs., 7 figs.

The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

Telecommunication sector of Pakistan is a significant contributor toward the economic development of Pakistan. However, telecommunication sector of Pakistan underwent a lot of changes from regulatory and marketing perspective in 2015, resulting in decreased cellular penetration, dropped down the cellular subscribers and decreased telecommunication revenue. Hence, this research paper is designed to validate the constructs used in addressing the moderating role of government regulations based on Oliver's four-stage loyalty model in telecom sector of Pakistan. This preliminary study has mainly employed the quantitative method (i.e. survey questionnaire), consisting of a total of 72 items related to eight constructs under study and used 7 points Likert scale. The main analysis method used is the reliability test of the constructs. The results reveal that the Cronbach alpha readings were between 0.756 and 0.932, indicating internally consistent and reliable measures of the constructs used. This result enables the constructs to be included in the actual data collection without change.

Prospects of Foreign Capital Raising for Russian Power Grid Companies

Directory of Open Access Journals (Sweden)

N. N. Shvets

2015-01-01

Full Text Available The power sector reform in Russia saw capital raising as one of the key objectives. Additional investments are necessary, in particular, for renovation of fixed assets which are ca. 70% worn out. The official Strategy for the development of the Russian power grid also provides for privatization of certain companies and foreign investors are considered among others as the target audience. Upon prospective privatization the sector is expected not only to experience a certain increase in capital expenditures, but also to benefit from foreign expertise and efficiency enhancement. At the moment, however, the privatization plans are hard to implement due to a number of obstacles. Prospective investors are mostly concerned about the lack of transparent regulation and clear development strategy of the industry. This is particularly relevant to the tariff system, which has been continuously altered in recent years. This might be explained by the need of the state support by other sectors, which is often provided at the expense of the power industry. Furthermore, the prospects of foreign capital raising are negatively influenced by the conflict in Ukraine and the corresponding negative perception of potential investors. The above factors result in the decrease in value of power grid companies as well as in the lack of visibility regarding the prospects of the sector development. Privatization thus becomes unreasonable both for the state and prospective investors. At the same time, despite the sector specifics, there are precedents of successful sale of power grid assets to private investors by international peers. Particularly, Vatenfall and Forum have recently closed relevant transactions, nothing to say about the power grid sector of Brazil, majorly controlled by private owners. Transparent regulation, clear pricing rules and well-balanced economic policy are, indeed, indispensable prerequisites for successful privatization. Those might back up a

The Cuban power sector faces a need for extensive investment in new generating capacity, under a large number of uncertainties regarding future conditions, including: rate of demand growth, fluctuations in fuel prices, access to imported fuel, and access to investment capital for construction of new power plants and development of fuel import infrastructure. To identify cost effective investment strategies under these uncertainties, a supply and power sector MARKAL model was assembled, following an extensive review of available data on the Cuban power system and resource potentials. Two scenarios were assessed, a business-as-usual (BAU) scenario assuming continued moderate electricity load growth and domestic fuel production growth, and a high growth (HI) scenario assuming rapid electricity demand growth, rapid increase in domestic fuel production, and a transition to market pricing of electricity. Within these two scenarios sets, sensitivity analyses were conducted on a number of variables. The implications of least-cost investment strategies for new capacity builds, investment spending requirements, electricity prices, fuel expenditures, and carbon dioxide emissions for each scenario were assessed. Natural gas was found to be the cost effective fuel for new generation across both scenarios and most sensitivity cases, suggesting that access to natural gas, through increased domestic production and LNG import, is a clear priority for further analysis in the Cuban context.

In this paper a method for regulating an alternating current voltage source with pair of IGBT transistor’s modules, in a full bridge configuration with series resonant converter is given. With the developed method a solution is obtained which can regulate the phase difference between output voltage and current through the inductor, in order to maintain maximum output power. Control electronic via feedback signals regulates the energy transfer to the tank by changing the pulse width of signals which are used as inputs to the gates of the IGBTs. By increasing or decreasing the pulse width transmitted to the various gates of the IGBT the energy transfer to the tank is increased or decreased . PowerSim simulations program is used for development of controlling methodology. Developed method is practically implemented in a prototype of the device for phase control of resonant converter with variable the resonant load. Key words: pulse width method, phase regulation , power converter.

Nuclear Power Plant 1996

Again this year, our magazine presents the details of the conference on Spanish nuclear power plant operation held in February and that was devoted to 1996 operating results. The Protocol for Establishment of a New Electrical Sector Regulation that was signed last December will undoubtedly represent a new challenge for the nuclear industry. By clearing stating that current standards of quality and safety should be maintained or even increased if possible, the Protocol will force the Sector to improve its productivity, which is already high as demonstrated by the results of the last few years described during this conference and by recent sectorial economic studies. Generation of a nuclear kWh that can compete with other types of power plants is the new challenge for the Sector's professionals, who do not fear the new liberalization policies and approaching competition. Lower inflation and the resulting lower interest rates, apart from being representative indices of our economy's marked improvement, will be very helpful in facing this challenge. (Author)

On 30 June 2006, the Federal Regulatory Agency (BNetzA) published its final report on the introduction of regulation by incentives according to Section 21a EnWG. The new regulation regime is to start on 1 January 2008. By this date, a starting value must be defined for the initial cost level and grid use reimbursements. Further, the interest rate for the capital contribution must be redefined (currently: 6.5 percent for the electricity sector and 7.8 percent for the gas sector). The contribution presents a regulation-economic method which takes account of individual parameteres in defining the capital contribution interest rate and of tax parameters and links these to current legal boundary conditions. As an example, the well-known CAPM is presented. (orig.)

Electricity has become an indispensable prerequisite for enhancing economic activity and improving human quality of life. Agricultural and industrial production processes are made more efficient through the use of electricity. Households need electricity for many purposes, including cooking, lighting, refrigeration, study and home-based economic activity. Essential facilities, such as hospitals, require electricity for cooling, sterilisation and refrigeration. Africa currently has 147 GW of installed capacity, a level comparable to the capacity China installs in one or two years. Average per capita electricity consumption in sub-Saharan Africa (excluding South Africa) is just 153 kWh/year. This is one-fourth of the consumption in India and just 6% of the global average. Nearly 600 million people in Africa lack access to electricity. Electricity blackouts occur on a daily basis in many African countries. Faced with this situation, people and enterprises often have to rely on expensive diesel power generation to meet their electricity needs, costing some African economies between 1% and 5% of GDP annually. To meet its growing demand Africa has an urgent need to raise the level of investment in its power sector. Analysis of a range of country and regional studies suggests the continent will need to add around 250 GW of capacity between now and 2030 to meet demand growth. This will require capacity additions to double to around 7 GW a year in the short-term and to quadruple by 2030. The magnitude of the investments required is such that governments will need public-private partnerships in order to scale up investment in generation capacity. While access rates are improving in some countries, the business environment and policy framework are still not sufficiently robust to attract the level of private investment required to install the additional 250 GW by 2030. Many African countries are burdened by opaque policy frameworks and excessive red tape, while electricity

De-regulated electric power markets and operating nuclear power plants: the case of British energy

International Nuclear Information System (INIS)

Hewlett, James G.

2005-01-01

One issue addressed in almost all electric power restructuring/de-regulation plans in both the United States (US) and the United Kingdom (UK) was the recovery of operating nuclear power plant's spent fuel disposal costs and the expenditures to decommission the units when they are retired. Prior to restructuring, in theory at least, in both countries, electricity consumers were paying for the back end costs from operating nuclear power plants. Moreover, in virtually all cases in the US, states included special provisions to insure that consumers would continue to do so after power markets were de-regulated. When power markets in the UK were initially restructured/de-regulated and nuclear power privatized, the shareholders of British Energy (BE) were initially responsible for these costs. However, after electricity prices fell and BE collapsed, the British government shifted many of the costs to future taxpayers, as much as a century forward. If this was not done, the book value of BE's equity would have been about -3.5 billion pounds. That is, BE's liabilities would have been about -3.5 billion pounds greater than their assets. It is difficult to see how BE could remain viable under such circumstances

Committing to coal and gas: Long-term contracts, regulation, and fuel switching in power generation

Science.gov (United States)

Rice, Michael

Fuel switching in the electricity sector has important economic and environmental consequences. In the United States, the increased supply of gas during the last decade has led to substantial switching in the short term. Fuel switching is constrained, however, by the existing infrastructure. The power generation infrastructure, in turn, represents commitments to specific sources of energy over the long term. This dissertation explores fuel contracts as the link between short-term price response and long-term plant investments. Contracting choices enable power plant investments that are relationship-specific, often regulated, and face uncertainty. Many power plants are subject to both hold-up in investment and cost-of-service regulation. I find that capital bias is robust when considering either irreversibility or hold-up due to the uncertain arrival of an outside option. For sunk capital, the rental rate is inappropriate for determining capital bias. Instead, capital bias depends on the regulated rate of return, discount rate, and depreciation schedule. If policies such as emissions regulations increase fuel-switching flexibility, this can lead to capital bias. Cost-of-service regulation can shorten the duration of a long-term contract. From the firm's perspective, the existing literature provides limited guidance when bargaining and writing contracts for fuel procurement. I develop a stochastic programming framework to optimize long-term contracting decisions under both endogenous and exogenous sources of hold-up risk. These typically include policy changes, price shocks, availability of fuel, and volatility in derived demand. For price risks, the optimal contract duration is the moment when the expected benefits of the contract are just outweighed by the expected opportunity costs of remaining in the contract. I prove that imposing early renegotiation costs decreases contract duration. Finally, I provide an empirical approach to show how coal contracts can limit

Outcomes, challenges and prospects for the Nordic network regulations

The deregulation of the electricity sector in the NordPool area has largely been a success story in terms of market organization and responsiveness. The joint market and the tight cooperation among the TSOs serve as an international benchmark in terms of transparency and market efficiency. However, the regulation models for the residual distribution network monopolies are surprisingly heterogeneous in terms of character, instruments and application. For primarily historical and institutional reasons, the Nordic countries have chosen different methods to regulate the sector, with interesting differences also in industrial structure. Whereas Finland and Sweden long maintained a 'light-handed' ex post approach based on enforced self-regulation, Norway adopted an ex ante increasingly high-powered revenue cap regime based on frontier analysis methods (DEA). Denmark, where the sector is dominated by cooperatively owned distributors, opted for high-powered model based on simple regression tools (COLS). In this paper, we present findings from a joint Nordic study on the challenges to the heterogeneous regulation models in the presence of increasing consolidation and supra-national regulatory convergence from the IEM directives. Based on an analysis based on surveys among stakeholders in the four countries, we investigate the feasibility and potential properties of a common Nordic regulation model. The paper is illustrated with a new Nordic operating efficiency analysis for the area, based on frontier analysis, showing the relative and absolute cost differences in the current decentralized regime.

Projects with large infrastructures, particularly those in the field of energy, provide a strong boost to certain industrial sectors in the country. In the case of Spain, the policy of direct management 'by components' of these projects - hydroelectric power plants, petrochemical plants, thermoelectric plants and nuclear power plants - adopted by the electric utility owners has furthered not only the local equipment manufacturing industry but also the engineering sector. At present, with full implementation of the Single Market in sight, it is particularly interesting for Spain to continue building up a powerful engineering sector, increasing its size and usefulness, and extending its traditional areas of action to other technologies, more on the lines of engineering and consulting firms in the USA than in the rest of Europe. The intention is to endow our equipment and construction companies with the skills necessary to enable them to compete with large European conglomerates in their respective sectors. The structure of these conglomerates usually contains engineering capabilities which are not habitual in our industry. Examples are given, showing how this model has been used to compete and win awards for important international projects. A specific analysis has been made of the position of Spanish engineering and industry in nuclear power generation projects in the former Soviet Union and East European countries, in which large investments are expected to be made.

This report estimates the market size and energy consumption of mobile off-road applications utilizing hydraulic fluid power, and summarizes technology gaps and implementation barriers. Mobile fluid power is the use of hydraulic fluids under pressure to transmit power in mobile equipment applications. The mobile off-road fluid power sector includes various uses of hydraulic fluid power equipment with fundamentally diverse end-use application and operational requirements, such as a skid steer loader, a wheel loader or an agriculture tractor. The agriculture and construction segments dominate the mobile off-road fluid power market in component unit sales volume. An estimated range of energy consumed by the mobile off-road fluid power sector is 0.36 - 1.8 quads per year, which was 1.3 percent - 6.5 percent of the total energy consumed in 2016 by the transportation sector. Opportunities for efficiency improvements within the fluid power system result from needs to level and reduce the peak system load requirements and develop new technologies to reduce fluid power system level losses, both of which may be facilitated by characterizing duty cycles to define standardized performance test methods. There are currently no commonly accepted standardized test methods for evaluating equipment level efficiency over a duty cycle. The off-road transportation sector currently meets criteria emissions requirements, and there are no efficiency regulations requiring original equipment manufacturers (OEM) to invest in new architecture development to improve the fuel economy of mobile off-road fluid power systems. In addition, the end-user efficiency interests are outweighed by low equipment purchase or lease price concerns, required payback periods, and reliability and durability requirements of new architecture. Current economics, low market volumes with high product diversity, and regulation compliance challenge OEM investment in commercialization of new architecture development.

Development of the Mexican electric power sector

Escofet, A.

1981-06-01

In 1980 Mexico had a population of 68 million, mostly concentrated in a few cities with many other areas being practically unpopulated. The country is semi-industrialized, and in order to achieve better standards of living, economic growth will have to continue at about 7.5 percent or more, particularly if the population continues to increase at 2.9 percent per year. The total installed electrical capacity at the end of 1980 was 14 600 MW; the per capita consumption of electricity was 910 KWh. The present government has as a goal an 8 percent annual growth rate in gross domestic product until 1995, resulting in forecast of a 12.5 percent growth rate in the electric sector to about 410 TWh per year. Hydroelectric power could be used to produce 80 TWh a year by 2000 if capacity were quadrupled. The use of coal for the production of electricity is beginning, and it is planned to generate 40 TWh a year from this source by 2000. Geothermal power should yield 20 TWh by then. A goal has been set of 20 000 MW of installed nuclear capacity by the end of the century; this would produce about 130 TWh, leaving some 280 TWh to be generated by oil or gas. The planned nuclear program must include the development of a strong Mexican nuclear industry, so that in 20 years 80 percent of the nuclear plant components could be locally produced. Ultimately it is hoped that Mexico will have the capability of installing, with its own resources, five or six large nuclear plants per year

Full Text Available This work presents a pathway for Saudi Arabia to transition from the 2015 power structure to a 100% renewable energy-based system by 2050 and investigates the benefits of integrating the power sector with the growing desalination sector. Saudi Arabia can achieve 100% renewable energy power system by 2040 while meeting increasing water demand through seawater reverse osmosis (SWRO and multiple effect distillation (MED desalination plants. The dominating renewable energy sources are PV single-axis tracking and wind power plants with 243 GW and 83 GW, respectively. The levelised cost of electricity (LCOE of the 2040 system is 49 €/MWh and decreases to 41 €/MWh by 2050. Corresponding levelised cost of water (LCOW is found to be 0.8 €/m3 and 0.6 €/m3. PV single-axis tracking dominates the power sector. By 2050 solar PV accounts for 79% of total electricity generation. Battery storage accounts for 41% of total electricity demand. In the integrated scenario, due to flexibility provided by SWRO plants, there is a reduced demand for battery storage and power-to-gas (PtG plants as well as a reduction in curtailment. Thus, the annual levelised costs of the integrated scenario is found to be 1–3% less than the non-integrated scenario.

Effectiveness of state climate and energy policies in reducing power-sector CO2 emissions

Science.gov (United States)

Martin, Geoff; Saikawa, Eri

2017-12-01

States have historically been the primary drivers of climate change policy in the US, particularly with regard to emissions from power plants. States have implemented policies designed either to directly curb greenhouse gas (GHG) emissions from power plants, or to encourage energy efficiency and renewable energy growth. With the federal government withdrawing from the global climate agreement, understanding which state-level policies have successfully mitigated power-plant emissions is urgent. Past research has assessed policy effectiveness using data for periods before the adoption of many policies. We assess 17 policies using the latest data on state-level power-sector CO2 emissions. We find that policies with mandatory compliance are reducing power-plant emissions, while voluntary policies are not. Electric decoupling, mandatory GHG registry/reporting and public benefit funds are associated with the largest reduction in emissions. Mandatory GHG registry/reporting and public benefit funds are also associated with a large reduction in emissions intensity.

Distributed power production in Mexico and Argentina: what are the new perspectives linked with the institutional reforms of the electric power sector?

International Nuclear Information System (INIS)

Islas, J.; Menanteau, Ph.

2004-01-01

Historically, the power systems are made from the progressive aggregation of small size local networks. Todays, this structure shows its limitations with an apparent exhausting of the gains linked with the size of production units, with the increasing difficulties to develop new transportation infrastructures, and with a fast performance improvement of the modular production technologies under the effect of the deregulation of the electric sector and of the policies of greenhouse gases abatement. Thus, it is not excluded that the distributed power production systems (i.e. gas and diesel engines, micro-turbines, small gas turbines and combined cycles, fuel cells, technologies using renewable energy sources) will play a more and more important role in the power supply, beside big production facilities. The factors influencing the development of these technologies can greatly change from one country to the other but some common established factors remain such as the search for a better reliability of supplies, the implementation of policies against climatic change or the deregulation of the electrical sector. The influence of these different factors are examined in this document which stresses more particularly on the consequences of the liberalization of network industries by using first, an analysis of the international experience, and then by examining the particular cases of Mexico and Argentina.

The demand for investment in the electricity sector in the world between 2000 and 2030 is estimated to be USD9.8 trillion. Developing countries would require more than half of this investment. Given the limited fiscal space for public investment, a number of developing countries have undertaken policy initiatives to improve the investment climate for the private sector. The pace, scope, sequencing and outcome of reform process varies across countries. This paper undertakes a comparative evaluation of policy and regulatory reforms in Argentina, Brazil, India, Mexico, PRC and Thailand. The paper concludes that apart from macroeconomic stability, the pace and sequencing of reforms influences private investment in the power sector. Distribution reforms and setting up of an independent regulatory institution reduces risk for investors. A peace-meal approach to reform keeps uncertainties alive for investors and does not translate in significant investment in the sector. (auth)

2015-12-01

Full Text Available The aim of the present study was to verify how accountants perceive the electric power companies in Brazil, regarding the use of economic valuation methods for measuring environmental impacts on hydroelectric power generation. These methods would be used in the internalisation of impacts in compliance with accounting theory criteria of recognition, measurement and disclosure of relevant economic activities. This is an exploratory study based on the conclusion regarding the collected data from a questionnaire answered by accountants, who worked in the electric power sector and were members of the Brazilian Electric Power Sector Accountants Association (ABRACONEE. The research showed that 74% of respondents were accountants or accounting analysts, 92% of them believed that companies should account for (internalise environmental impacts caused by their activities, and 75% of them believed that this task should be based on detailed and specific norms determining what should be done and when and how to do it. Despite their high level of accounting knowledge and complete familiarity with the changes determined by the Brazilian Securities Commission, respondents adopted a conservative stance in relation to the use of estimated values or those obtained in hypothetical markets. The study revealed the existence of a vast field of research that has yet to be explored by accounting in the field of environmental accounting, especially in terms of both measurement and recognition of environmental impacts caused by diverse economic activities

Full Text Available With the antimonopoly regulation in the domestic economy getting more stringent an analysis of the current measures of antimonopoly regulation in terms of their efficiency is now becoming ever more relevant. The aim of the study - analyze how the measures of antimonopoly regulation affect competitive relationships in the electric power industry. The following methods have been used in this work: empirical method, cause-effect method and scientific abstraction method. The article sets out an analysis of the antimonopoly regulation measures that the antimonopoly authority applies. It also provides an assessment of consequences that follow from such methods being applied for the promotion of competitive relationships on the market of electric power and capacity. A conclusion has been reached that the antimonopoly regulation measures being applied impede the progress of competitive relationships on the market of electric power and capacity. The continuing process of reformation in electric power industry aims to liberalize relationships in the area of electric power production. Yet, as a result of this process, generating capacities are becoming increasingly more concentrated mainly around state companies. This is mainly caused by the lack of certainty regarding the results of the industry reformation and a more stringent state regulation over the last years of the reforms. At the same time, for the purposes of limiting the market force, measures of antimonopoly regulation are being applied to generating companies. Such measures have an adverse effect on competitive relationships and stimulate further concentration.

Costs of Reducing Greenhouse Gas Emissions: A Case Study of India’s Power Generation Sector

OpenAIRE

Climate change impacts on air temperatures and water availability have the potential to alter future electricity sector investment decisions as well as the reliability and performance of the power sector. Different electricity sector configurations are more or less vulnerable to climate-induced changes. For example, once-through cooled thermal facilities are the most cost-effective and efficient technologies under cooler and wetter conditions, but can be substantially affected by and vulnerable to warmer and drier conditions. Non-thermal renewable technologies, such as PV and wind, are essentially "drought-proof" but have other integration and reliability challenges. Prior efforts have explored the impacts of climate change on electric sector development for a limited set of climate and electricity scenarios. Here, we provide a comprehensive suite of scenarios that evaluate how different electricity sector pathways could be affected by a range of climate and water resource conditions. We use four representative concentration pathway (RCP) scenarios under five global circulation models (GCM) as climate drivers to a Water Balance Model (WBM), to provide twenty separate future climate-water conditions. These climate-water conditions influence electricity sector development from present day to 2050 as determined using the Regional Energy Deployment Systems (ReEDS) model. Four unique electricity sector pathways will be considered, including business-as-usual, carbon cap, high renewable energy technology costs, and coal reliance scenarios. The combination of climate-water and electricity sector pathway scenarios leads to 80 potential future cases resulting in different national and regional electricity infrastructure configurations. The vulnerability of these configurations in relation to climate change (including in-stream thermal pollution impacts and environmental regulations) is evaluated using the Thermoelectric Power and Thermal Pollution (TP2M) model, providing

The restructuring of Africa's electricity sector : lessons learned

International Nuclear Information System (INIS)

Fall, A.

2008-01-01

The challenges facing the electricity sector in Africa was discussed with particular reference to financial constraints and the inefficient management of public utilities. The 2 types of reform in the electricity sector include the disengagement of the State for the benefit of the private sector, and the restructuring of the electrical industry to include competition for greater efficiency in the sector. The first reform in Africa involved the opening of the sector to private enterprises without the restructuring of the industry. With the exception of Uganda, the evolution of the restructuring did not include a complete de-integration in the transitional stage. Restructuring involved systematic independent production; a single buyer model with a limited period of monopoly on bulk purchase; access to third party on the networks; empowerment of regulation by the creation of an independent body responsible for regulation; and, establishment of a rural electrification agency. In more advanced countries such as Egypt, Algeria and Nigeria, the creation of a holding company with legally separated subsidiaries was retained. One of the major problems was financial investment, technical performances and the extension of electrical access. Low competition, or low negotiation capabilities led to unbalanced contracts in favour of private promoters. In general, rates for electrical energy increased due to the reform, with the lowering of public resources at the profit of private funding, notably in the independent production of thermal energy versus hydroelectric energy. The results have been mixed due to the breakdown of public versus private partnerships in many countries, with the disengagement of the State. Independent power production has raised problems of sustainability and environmental issues, as well as social problems, price control, as well as accessibility in rural settings. 7 refs., 1 fig

Challenges for Sustainable Energy Sectors in Developing Countries- with Case Studies from Zambia, Zimbabwe, India and Thailand

Energy Technology Data Exchange (ETDEWEB)

Andersen, Regine

1998-12-31

Most of the developing countries have severe constraints on economic development caused by serious problems in their power sector. This report analyses the technical and financial situation of the sector from the perspective of sustainable electricity strategies. The core problem of the electricity sector is the complete lack of energy efficiency at all levels from generation to end user. The current emphasis on private participation in new electricity generation projects fails to solve the core problem and even diverts attention from the real challenge. An arm`s length relationship between governments and utilities is of central importance for a sound performance of the power sector. But more autonomous power sector decisions, such as reformed tariff structures, might contribute to inflation and political unrest. This is a main barrier to steps towards power sector autonomy. Another barrier is the lack of institutional capacity, despite over staffed utilities. Most important is the fact that the organizational structures are designed for supply-side management and that the incentive structures for good performance are often weak. The case of Thailand shows that end-use efficiency can be developed considerably by means of incentives and regulations and that transparency was an important condition for achieving this. The real challenge for development cooperation is to support the improvement of energy efficiency at all levels and the institutional and financial preconditions. It is also an important challenge to support developing countries in preparing for future utilization of viable new renewable energy carriers. Apart from this, it is important to continue the work for environmental impact assessments of planned power projects, and to support measures for minimizing the environmental impacts of old power plants. 48 refs., 2 figs.

An essential guideline for the implementation of power quality regulation - or any regulation for that matter - is that it needs to find the right balance between the interests of the different stakeholders. This is particularly important when assessing the inconvenience caused to customers by the failures in the electricity supply. Customers' experiences should obviously not be underestimated but it is equally important that excessive requirements concerning the power quality developments are not laid on the distribution companies, either - especially if they are not provided with adequate means to carry out the necessary developments. After all, regulation should encourage innovations, both organisational and technological, that benefit the industry in the long run - this applies to power quality developments as well as any other developments within the industry. Failing to do this, the investors will soon loose their interest in the electricity distribution business, and this will be extremely harmful for the capital-intensive industry. Regulators are currently developing versatile power quality regulation schemes in different countries. At this point it might be worth considering what benefits could be achieved if the framework for the power quality regulation schemes that are applied in different countries was the same - after all the goals are principally the same anyway. One of the obvious benefits would be that the regulators would have more comparable data on the observed power quality levels in different countries. In addition, those companies that operate in various markets could more easily transfer their best practices concerning the power quality developments from one market to another

Zhang, Dongjie; Liu, Pei; Ma, Linwei; LI, Zheng

2013-01-01

A great challenge China's power sector faces is to mitigate its carbon emissions whilst satisfying the ever-increasing power demand. Optimal planning of the power sector with consideration of carbon mitigation for a long-term future remains a complex task, involving many technical alternatives and an infinite number of possible plants installations, retrofitting, and decommissioning over the planning horizon. Previously the authors built a multi-period optimization model for the planning of China's power sector during 2010–2050. Based on that model, this paper executed calculations on the optimal pathways of China's power sector with two typical decision-making modes, which are based on “full-information” and “limited-information” hypothesis, and analyzed the impacts on the optimal planning results by two typical types of carbon tax policies including a “continuous and stable” one and a “loose first and tight later” one. The results showed that making carbon tax policy for long-term future, and improving the continuity and stability in policy execution can effectively help reduce the accumulated total carbon emissions, and also the cost for carbon mitigation of the power sector. The conclusion of this study is of great significance for the policy makers to make carbon mitigation policies in China and other countries as well. - Highlights: • A multi-stage optimization model for planning the power sector is applied as basis. • Difference of ideal and actual decision making processes are proposed and analyzed. • A “continuous and stable” policy and a “loose first and tight later” one are designed. • 4 policy scenarios are studied applying the optimal planning model and compared. • The importance of “continuous and stable” policy for long term is well demonstrated

Impact of the Power Sector Development on the Emission Level in Lithuania

International Nuclear Information System (INIS)

Galinis, A.; Tarvydas, D.

1998-01-01

The analyses carried out show that further necessary investments into safety improvements of the Ignalina NPP satisfy the criterion of the least cost power sector development and it should be kept in operation until the end of its technical life time. Modular CHP with diesel engines or gas turbines, or new CCGT will be the most attractive source of electricity generation if new capacities are required. The Ignalina NPP also has crucial impact on all kind of emissions in Lithuania. If this power plant is shut down, the requirement of the Kyoto Protocol for CO 2 mitigation will be violated already in 2011, even in the case of the most pessimistic economy growth and electricity export scenario. In the case of the further operation of the nuclear power plant Lithuania will be able to fulfil the requirement of the Kyoto Protocol during the whole study period. However, during temporary shut down of the nuclear plant for safety upgrade or rechannelling of reactors some reduction of electricity export will be necessary. (author)

This study analyzes the potential impacts of changes in temperature due to climate change on the U.S. power sector, measuring the energy, environmental, and economic impacts of power system changes due to temperature changes under two emissions trajectories—with and without emissions mitigation. It estimates the impact of temperature change on heating and cooling degree days, electricity demand, and generating unit output and efficiency. These effects are then integrated into a dispatch and capacity planning model to estimate impacts on investment decisions, emissions, system costs, and power prices for 32 U.S. regions. Without mitigation actions, total annual electricity production costs in 2050 are projected to increase 14% ($51 billion) because of greater cooling demand as compared to a control scenario without future temperature changes. For a scenario with global emissions mitigation, including a reduction in U.S. power sector emissions of 36% below 2005 levels in 2050, the increase in total annual electricity production costs is approximately the same as the increase in system costs to satisfy the increased demand associated with unmitigated rising temperatures. - Highlights: • We model the impact of rising temperatures on the U.S. power sector. • We examine temperature and mitigation impacts on demand, supply, and investment. • Higher temperatures increase power system costs by about $50 billion by the year 2050. • Meeting demand from higher temperatures costs slightly more than reducing emissions. • Mitigation policy cost analyses should account for temperature impacts

The Liberalisation Process of the Spanish Electricity Sector

International Nuclear Information System (INIS)

Alonso, P. R.

2001-01-01

At the beginning of 1998, the 54/1997 Electricity Law entered into force, introducing a new configuration for the Spanish electricity system. Before this, the electric utilities and the Spanish Ministry of Industry and Energy signed a Protocol outlining the general structure of the future changes which would lead to the transformation of the Spanish electricity system from one based on a central purchasing agent model to one based on wholesale and retail competition. The structure of the power industry prior to the 54/1997 Electricity Law consisted of a number of vertically integrated electricity companies, most of them privately owned. One company (REE, Red Electrica de Espana) controlled by the State, was the System Operator, with the property of most of the Transmission Network. This company was created in 1984, as an attempt to improve overall efficiency in the sector by central co-ordination of all available resources and by central planning of new investments. Later, in 1987 a New Legal Framework (Marco Legal Estable) was established in order to assure financial stabilisation to the electric utilities, fixing revenues based on standard costs and setting a National tariff system. The start for the liberalisation process began with the 1994 Electricity Act (LOSEN) with the creation of the Regulatory Commission and the allowance to open access to new entrants. The Spanish electricity model finally set in 1998 seeks the introduction of competitiveness in the power sector through a few basic principles: Shorter state intervention by rationalisation of the energy policy constraints and by leaving to the market forces the system operation and planning (except for transmission planning); Separation of activities: Regulated activities (transmission and distribution) are separated form non-regulated activities (generation, trading); The design of a bulk power competitive market, including competition in generation, freedom of entry, a power pool managed by a market

Full Text Available The aim of the article is to study the theoretical and methodological principles of the state regulation and accounting and analytical support of the development of e-commerce in the consumer sector. The peculiarities of the state regulation and accounting and analytical support of the development of e-commerce in the consumer sector have been considered. The international and domestic experience in the field of regulatory support of e-commerce is studied. There systematized the ways of solving the problems of e-commerce in Ukraine based on the need to minimize the direct regulation with the perfection of the institutional environment to improve business conditions including the issues of the fiscal regime and simplification of the customs tariff regulation. The state regulation of e-commerce should constructively contribute to the development of entrepreneurship among other measures by solving the problem of financial control of electronic transactions and supporting the payment infrastructure of e-commerce in the consumer market on the basis of its corresponding accounting and analytical support. Prospects of further research in this direction are definition of a clear and harmonized with international standards state policy in the sphere of regulation of e-commerce in the consumer market on the basis of the relevant accounting and analytical support, since the appearance of new objects and forms of economic activity sets new tasks for the accounting, which develops in parallel with these changes and generates information for managing at both the micro and macro level.

Energy transition in transport sector from energy substitution perspective

Sun, Wangmin; Yang, Xiaoguang; Han, Song; Sun, Xiaoyang

2017-10-01

Power and heating generation sector and transport sector contribute a highest GHG emissions and even air pollutions. This paper seeks to investigate life cycle costs and emissions in both the power sector and transport sector, and evaluate the cost-emission efficient (costs for one unit GHG emissions) of the substitution between new energy vehicles and conventional gasoline based vehicles under two electricity mix scenarios. In power sector, wind power and PV power will be cost comparative in 2030 forecasted with learning curve method. With high subsidies, new energy cars could be comparative now, but it still has high costs to lower GHG emissions. When the government subsidy policy is reversible, the emission reduction cost for new energy vehicle consumer will be 900/ton. According to the sensitive analysis, the paper suggests that the government implement policies that allocate the cost to the whole life cycle of energy production and consumption related to transport sector energy transition and policies that are in favor of new energy vehicle consumers but not the new energy car producers.

Future wind power forecast errors, need for regulating power, and costs in the Swedish system

Wind power is one of the renewable energy sources in the electricity system that grows most rapid in Sweden. There are however two market challenges that need to be addressed with a higher proportion of wind power - that is variability and predictability. Predictability is important since the spot market Nord Pool Spot requires forecasts of production 12 - 36 hours ahead. The forecast errors must be regulated with regulating power, which is expensive for the actors causing the forecast errors. This paper has investigated a number of scenarios with 10 - 55 TWh of wind power installed in the Swedish system. The focus has been on a base scenario with 10 TWh new wind power consisting of 3,5 GW new wind power and 1,5 GW already installed power, which gives 5 GW. The results show that the costs for the forecast errors will increase as more intermittent production is installed. However, the increase can be limited by for instance trading on intraday market or increase quality of forecasts. (orig.)

Implications of renewable energy technologies in the Bangladesh power sector. Long-term planning strategies

Energy Technology Data Exchange (ETDEWEB)

Mondal, Alam Hossain

2010-10-04

Bangladesh is facing daunting energy challenges: Security concerns over growing fuel imports, limited domestic energy resources for power generation, and projected demands for electricity that will exceed domestic supply capabilities within a few years. By acknowledging the potential of renewable energy resources, the country could possibly meet its unprecedented energy demand, thus increasing electricity accessibility for all and enhancing energy security through their advancement. The integration of renewable energy technologies in the power sector through national energy planning would, therefore, be a step in the right direction, not only for sustainable development of the country but also as part of Bangladesh's responsibility toward the global common task of environmental protection. This study estimates the potential of renewable energy sources for power generation in Bangladesh from the viewpoint of different promising available technologies. Future long-term electricity demand in Bangladesh is projected based on three economic growth scenarios. The energy planning model LEAP is applied to forecast the energy requirements from 2005 to 2035. Different policy scenarios, e.g., accelerated renewable energy production, null coal import, CO2 emission reduction targets and carbon taxes in the power sector from 2005 to 2035 are explored. The analyses are based on a long-term energy system model of Bangladesh using the MARKAL model. Prospects for the power sector development of the country are identified, which ensure energy security and mitigate environmental impacts. The technical potential of grid-connected solar photovoltaic and wind energy are estimated at 50174 MW and 4614 MW, respectively. The potential of energy from biomass and small hydro power plants is estimated at 566 MW and 125 MW, respectively. Total electricity consumption was 18 TWh in 2005 and is projected to increase about 7 times to 132 TWh by 2035 in the low GDP growth scenario. In the

A lot left over: Reducing CO2 emissions in the United States’ electric power sector through the use of natural gas

International Nuclear Information System (INIS)

Lafrancois, Becky A.

2012-01-01

As the leading contributor of greenhouse gas emissions, the electricity sector stands to be impacted by policies seeking to curtail emissions. Instead of increasing electricity from renewable resources or nuclear power facilities, an alternative approach to reducing emissions in the electric power sector is changing the dispatch order of fossil fuels. Important differences between fossil fuels, and in the technologies used to burn them, make it possible to substantially reduce emissions from the sector. On average, each gigawatt-year of electricity generation switched from coal to natural gas reduces CO 2 emissions by 59 percent. As a result of significant investments in natural gas fired power plants in the United States between 1998 and 2005, there is an opportunity for electricity producers to take advantage of underutilized capacity. This is the first study to closely examine the new capital additions and analyze the technical potential for reductions in emissions. The analysis finds that 188 GW of capacity may be available to replace coal-fired baseload electricity generation. Utilizing this excess gas-fired capacity will reduce the sector's CO 2 emissions by 23 to 42 percent and reduce overall U.S. CO 2 emissions between 9 percent and 17 percent. - Highlights: ► Utilizing recently built natural gas fired power plants can significantly reduce CO 2 emissions in the United States. ► CO 2 emissions from electricity production can be reduced by 23–42 percent. ► U.S. overall CO 2 emissions reduced by 9–17 percent.

This paper examines the potential effects that emerging mandatory carbon markets have for voluntary markets for renewable energy, or green power markets. In an era of carbon regulation, green power markets will continue to play an important role because many consumers may be interested in supporting renewable energy development beyond what is supported through mandates or other types of policy support. The paper examines the extent to which GHG benefits motivate consumers to make voluntary renewable energy purchases and summarizes key issues emerging as a result of these overlapping markets, such as the implications of carbon regulation for renewable energy marketing claims, the demand for and price of renewable energy certificates (RECs), and the use of RECs in multiple markets (disaggregation of attributes). It describes carbon regulation programs under development in the Northeast and California, and how these might affect renewable energy markets in these regions, as well as the potential interaction between voluntary renewable energy markets and voluntary carbon markets, such as the Chicago Climate Exchange (CCX). It also briefly summarizes the experience in the European Union, where carbon is already regulated. Finally, the paper presents policy options for policymakers and regulators to consider in designing carbon policies to enable carbon markets and voluntary renewable energy markets to work together.

2013-01-01

There are continuous debates around the question of whether CDM really contributes to sustainable development (SD) in host countries. Employment impact is an essential indicator of SD. Based on an input-out approach this research builds a quantitative assessment model to evaluate the employment impacts of CDM. Both direct and indirect jobs creation and job losses of CDM projects in the power sector registered by the end of 2011 are calculated by project types and power grids where the project is located. Results of this study show that, although the above mentioned CDM projects causes about 99,000 net direct job losses, they also create about 3.08 million indirect jobs, resulting in the gross employment of CDM to be about 2.98 million. Thereof, hydro projects induce both direct and indirect job losses, which comes to approximately 0.89 million. Solar projects have the most potential since they own the highest indirect jobs created by one GWh generation, about 104 jobs/GWh. - Highlights: • An input–output model was built for assessment of CDM projects' employment impact; • CDM projects create direct and indirect jobs while cause some losses in short. • Significant indirect job gains of CDM projects were found; • Solar projects cause 104 jobs/GWh in average, ranking as the highest contributor

Electric power globalization and reforming; Globalizacao e reforma do setor eletrico

The study examines the dynamics of carbon emissions baselines of electricity generation in Indian states and Chinese provinces in the backdrop of ongoing electricity sector reforms in these countries. Two Indian states-Gujarat and Andhra Pradesh, and three Chinese provinces-Guangdong, Liaoning and Hubei have been chosen for detailed analysis to bring out regional variations that are not captured in aggregate country studies. The study finds that fuel mix is the main driver behind the trends exhibited by the carbon baselines in these five cases. The cases confirm that opportunities exist in the Indian and Chinese electricity sectors to lower carbon intensity mainly in the substitution of other fuels for coal and, to a lesser extent, adoption of more efficient and advanced coal-fired generation technology. Overall, the findings suggest that the electricity sectors in India and China are becoming friendlier to the global environment. Disaggregated analysis, detailed and careful industry analysis is essential to establishing a power sector carbon emissions baseline as a reference for CDM crediting. However, considering all the difficulties associated with the baseline issue, our case studies demonstrate that there is merit in examining alternate approaches that rely on more aggregated baselines

1991-02-01

The Nuclear Regulatory Commission (NRC) monitors incentive programs established by state regulators in order to obtain current information and to consider the potential safety effects of the incentive programs as applied to nuclear units. The current report is an update of NUREG/CR-5509, Incentive Regulation of Nuclear Power Plants by State Public Utility Commissions, published in December 1989. The information in this report was obtained from interviews conducted with each state regulator and each utility with a minimum entitlement of 10%. The agreements, orders, and settlements from which each incentive program was implemented were reviewed as required. The interviews and supporting documentation form the basis for the individual state reports describing the structure and financial impact of each incentive program. The programs currently in effect represent the adoption of an existing nuclear performance incentive program proposal and one new program. In addition, since 1989 a number of nuclear units have been included in one existing program; while one program was discontinued and another one concluded. 6 refs., 27 tabs

Lifetime Management in Non-US-Technology Nuclear Power Plants using US Regulations

Cornelius Steenkamp, J.; Encabo Espartero, J.; Garcia Iglesias, R.

2013-01-01

In July 2009 the Spanish Nuclear Regulator (CSN) issued a Safety Instruction (IS-22) for the development of Lifetime Management in the Nuclear Power Plants within Spain. The context of this Safety Instruction is based on the American Regulations 10CFR54, NUREG1800/1801 and the technical guide NEI95-10. All these regulations are aimed at US-Technology Nuclear Power Plants. Lifetime Management of Nuclear Power Plants with a plant design different from US technologies can most certainly be developed with the mentioned US regulations. The successful development of Lifetime Management in these cases depends on the adaptation of the different requirements of the regulations. Challenges resulting from the adaptation process can be resolved by taking into consideration the plant design of the plant in question.

[Mechanism and implication of regulation of the pricing of essential medicines in the private pharmaceutical sector in Mali].

Science.gov (United States)

Maïga, D; Maïga, S; Maïga, M D

2010-04-01

The healthcare and pharmaceutical professions in Mali were privatized in 1985. Privatization led to swift expansion of the private sector and upset the balance that had existed between the public and private sectors. A national pharmaceutical policy did not emerge until a decade later. Its purpose was to promote a system ensuring fair access to essential generic medicines for all. It was hoped that synergy between the two sectors would promote that objective. However, the policy calling for distribution of essential generic medicine through the private sector was not accompanied by an adequate system for pricing. This problem led the government to adopt a price regulation policy to realign market dynamics with public health goals. This experience shows that a sustained effort from public policy makers is necessary to prevail against the professional and business interests that can conflict with the public interest. Analysis of this experience also demonstrates the need to improve, restructure, and control the pharmaceutical industry. The government must continue to play its crucial role in the context of limited resources and inequality between consumers and pharmaceutical companies.

Approximately 80% of the world's electricity supply depends on reliable water resources. Thermoelectric and hydropower plants have been impacted by low flows and floods in recent years, notably in the US, Brazil, France, and China, amongst other countries. The dependence on reliable flows imputes a large vulnerability to the electricity supply system due to hydrological variability and the impacts of climate change. Using an updated dataset of global electricity capacity with global climate and hydrological data from the ISI-MIP project, we present an overview analysis of power sector vulnerability to hydroclimatic risks, including low river flows and peak flows. We show how electricity generation in individual countries and transboundary river basins can be impacted, helping decision-makers identify key at-risk geographical regions. Furthermore, our use of a multi-model ensemble of climate and hydrological models allows us to quantify the uncertainty of projected impacts, such that basin-level risks and uncertainty can be compared.

Modak, Nabanita; Spence, Kelley; Sood, Saloni; Rosati, Jacky Ann

2015-01-01

Air emissions from the U.S. pulp and paper sector have been federally regulated since 1978; however, regulations are periodically reviewed and revised to improve efficiency and effectiveness of existing emission standards. The Industrial Sectors Integrated Solutions (ISIS) model for the pulp and paper sector is currently under development at the U.S. Environmental Protection Agency (EPA), and can be utilized to facilitate multi-pollutant, sector-based analyses that are performed in conjunction with regulatory development. The model utilizes a multi-sector, multi-product dynamic linear modeling framework that evaluates the economic impact of emission reduction strategies for multiple air pollutants. The ISIS model considers facility-level economic, environmental, and technical parameters, as well as sector-level market data, to estimate the impacts of environmental regulations on the pulp and paper industry. Specifically, the model can be used to estimate U.S. and global market impacts of new or more stringent air regulations, such as impacts on product price, exports and imports, market demands, capital investment, and mill closures. One major challenge to developing a representative model is the need for an extensive amount of data. This article discusses the collection and processing of data for use in the model, as well as the methods used for building the ISIS pulp and paper database that facilitates the required analyses to support the air quality management of the pulp and paper sector.

A decomposition analysis of the driving factors of CO_2 (Carbon dioxide) emissions from the power sector in the European Union countries

International Nuclear Information System (INIS)

Karmellos, M.; Kopidou, D.; Diakoulaki, D.

2016-01-01

The scope of this paper is to investigate the driving factors of CO_2 emissions from electricity generation in all European Union countries (EU-28) during the period 2000–2012. Particular emphasis is placed on the assessment of any potential association between the examined driving factors and major climate and energy policies implemented during the examined period. In addition, the analysis distinguishes two subperiods, namely 2000–2007 and 2007–2012 in order to detect the impact of the economic crisis on each distinct driving factor and, consequently, on the total level of CO_2 emissions from the power sector. The model developed to analyse the changes in CO_2 emissions from the power sector across EU-28, is based on LMDI-I method and takes into account five driving factors: level of activity, electricity intensity, electricity trade, efficiency of electricity generation and fuel mix. The obtained results show that in times of economic growth the main factor counterbalancing the activity effect was in most countries the decreasing electricity intensity, while the contribution of all other factors becomes apparent later, despite the economic crisis and in view of the Kyoto targets. - Highlights: • LMDI is used to identify driving forces of CO_2 emissions from EU's power sector. • Declining electricity intensity was the main restrictive factor before 2007. • Fuel shifts contributed to emissions fall mostly after 2007, despite the crisis. • Trade effect is notable and indicates growing carbon leakage in the power sector.

The origin of the accident prevention regulation - ''Thermal Power Stations'' is attributable mainly to two tragic accidents. It has made organizational changes and interventions in the operational process necessary in thermal power stations. Emphasis is laid upon the consistent issue of written permits-to-work on plant components carrying a heating medium and operating under pressure and on written operating licences for the operation of boilers. The paper describes additional ways in which regulation influences the daily practices of the power station operator. Brief references is made to the draft of the revised regulation. (orig./HP) [de

Building new WDM regulations for the Namibian tourism sector on factors influencing current water-management practices at the enterprise level

Science.gov (United States)

Schachtschneider, Klaudia

Namibia's aridity is forcing its water sector to resort to new water resource management approaches, including water demand management (WDM). Such a change in management approach is facilitated through the country's opportunity at independence to rewrite and adapt its old policies, including those for water and tourism. Legal support for WDM through the Water Act and other sector-specific Acts is crucial to plan the practical implementation of WDM throughout the different water use sectors of Namibia. In order to be able to put the policy into practice, it is imperative to understand which factors motivate people to adopt WDM initiatives. Within the Namibian tourism industry three main factors have been identified which influence the water-management approaches at tourist facilities. This paper discusses how the water and tourism decision makers can consider these factors when developing new regulations to introduce WDM in the tourism sector.

Lightweight Battery Charge Regulator Used to Track Solar Array Peak Power

Soeder, James F.; Button, Robert M.

1999-01-01

A battery charge regulator based on the series-connected boost regulator (SCBR) technology has been developed for high-voltage spacecraft applications. The SCBR regulates the solar array power during insolation to prevent battery overcharge or undercharge conditions. It can also be used to provide regulated battery output voltage to spacecraft loads if necessary. This technology uses industry-standard dc-dc converters and a unique interconnection to provide size, weight, efficiency, fault tolerance, and modularity benefits over existing systems. The high-voltage SCBR shown in the photograph has demonstrated power densities of over 1000 watts per kilogram (W/kg). Using four 150-W dc-dc converter modules, it can process 2500 W of power at 120 Vdc with a minimum input voltage of 90 Vdc. Efficiency of the SCBR was 94 to 98 percent over the entire operational range. Internally, the unit is made of two separate SCBR s, each with its own analog control circuitry, to demonstrate the modularity of the technology. The analog controllers regulate the output current and incorporate the output voltage limit with active current sharing between the two units. They also include voltage and current telemetry, on/off control, and baseplate temperature sensors. For peak power tracking, the SCBR was connected to a LabView-based data acquisition system for telemetry and control. A digital control algorithm for tracking the peak power point of a solar array was developed using the principle of matching the source impedance with the load impedance for maximum energy transfer. The algorithm was successfully demonstrated in a simulated spacecraft electrical system at the Boeing PhantomWorks High Voltage Test Facility in Seattle, Washington. The system consists of a 42-string, high-voltage solar array simulator, a 77-cell, 80-ampere-hour (A-hr) nickel-hydrogen battery, and a constant power-load module. The SCBR and the LabView control algorithm successfully tracked the solar array peak

Full Text Available Energy security defined as how to equitably provide available, affordable, reliable efficient, environmentally friendly, proactively governed and socially acceptable energy services to end user. It has in recent years taken attention of policymakers in different parts of the world. Formulating policy to improve energy security is mandatory, not only because of depleting fossil resource, but also implementing diversity of energy source since utilization abundant renewable energy resources can increase the security of energy supply. One of the abundant renewable energy resources in Indonesia is palm oil. This study analyses the utilization of palm biodiesel for Indonesian power generation sector in the Java-Madura-Bali (JAMALI system. Two scenarios were created by projecting the demand and environmental impact as well as GHG emissions reduction over the next 25 years. The first scenario subjects on current energy policy, while the second scenario is to substitute of fossil fuel which is still used in the JAMALI power generation system. Effect of palm biodiesel on emission of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, Nitrogen Oxides, Particulate Matter, and Volatile Organic Compounds were estimated for each scenario. An externality analysis to complete the environmental analysis was conducted and resource analysis of palm oil plantation based biodiesel was also estimated. Finally, the economics feasibility of palm biodiesel in the power generation sector was analyzed.

The electric utility industries in most African countries are confronted by the twin-problem of deficient capacity and lack of adequate financial resources to undertake capacity expansion of their respective systems. The critical aspects of power sector reform taking place in many countries are the shift away from state-owned monopoly model towards private sector participation and some competition in the industry. Hydropower plants dominate power system in most countries in the region. Ghana, which is the focus of this study, has such characteristics. The hydrology of the river on which the two dams (Akosombo and Kpong hydropower plants) are built is increasingly becoming uncertain, and besides, the power output from the two plants is insufficient to meet the increasing electricity demand of the country. The alternative is to build thermal power plants to complement the two hydropower plants. The purposes of the study are: (i) to assess the environmental (more specifically air pollution) implications of changing fuel mix in power generation in Ghana within the context of the ongoing reform of the power sector and (ii) to assess the capacity of the environment protection agencies to regulate, monitor and enforce regulations in the emerging electricity industry. The study uses a spreadsheet-based simulation model to determine the potential levels of certain air pollutants - CO{sub 2}, SO{sub 2} and NO{sub x} - that would result from changes in fuel mix for electricity generation. Using different capacity expansion options proposed for The Volta River Authority (VRA) between 1997-2013, the levels of these air pollutants are estimated. The study further describes other potential environmental impacts of changes in fuel mix in power generation. (au)

We present a feasibility study that has been carried out to determine the best power regulation strategy for the PET front-end electronics of the trimodal PET/MRI/EEG TRIMAGE scanner. Conventional power regulation strategies cannot be applied to PET/MRI because standard switching regulators stop working in presence of a high magnetic field. At the state of the art, linear regulators are used instead. However, linear regulators are inefficient and might not allow to fulfill power and thermal constraints if the electronics becomes more power demanding, such as in the case of FPGA based front-ends. Very recently, a new generation of switching power supplies has been introduced for EMI critical applications where the discrete inductor energy buffer is not allowed. These supplies have very small footprint, need few biasing peripherals and they use on-chip integrated inductors for energy storage. These switching power regulators coupled with an adequate EMI shield could be an achievable power solution for our PET front-end electronics. Test procedures for Enpirion. EN2390QI and the Enpirion. EN6347QI switching power regulators are presented. Measurements have been performed at GE 1.5T MRI scanner with the support of IRCCS Fondazione Stella Maris. All the board have been tested in two different configurations: with and without an additional EMI shield. Performance of these two switching power regulators have been compared with a linear power regulator (Enpirion. EY1501DI). Output voltage, output current and temperature have been measured. The stability of these three main characteristic will be presented in different operation conditions and will be discussed (output voltage vs. temperature, output voltage vs. output current and output current vs. temperature).

Efficient use of green taxes in the CHP sector

Skovsgaard Nielsen, L.; Mognesen, Martin Frank; Pade, L.L.

2007-06-01

Since 1977 green taxes have been used in the Danish power and heat sector. Green taxes principally assure an efficient, market-based reduction of pollution by reducing the energy consumption or increasing the share of renewable energy in power and heat production. This report takes its point of departure in four potential barriers which prevent a marketbased, cost-effective increase of the proportion of renewable energy in power and heat production. We primarily concentrate on three policy measures. 5. green and lessgreen taxes; 6. mandatory combined heat and power production; 7. fuel restrictions. Furthermore, we analyse a fourth characteristic in the law: 8. high transactions costs connected to the enlargement of renewable energy. The purpose of the report is to describe how the four potential barriers contradict the theoretically efficient application of green taxes in the power and heat sector. We do this: 1) by clarifying how legislation in the power and heat sector affects the extension of renewable energy; and 2) by evaluating the theoretically efficient application of green taxes in the power and heat sector in relation to legislation.

The objective of this study is to examine factors and prospects for a resumption in growth of nuclear power in the United States over the next decade. The focus of analysis on the likelihood that current efforts in the United States to develop improved and safer nuclear power reactors will provide a sound technical basis for improved acceptance of nuclear power, and contribute to a social/political climate more conducive to a resumption of nuclear power growth. The acceptability of nuclear power and advanced reactors to five social/political sectors in the U.S. is examined. Three sectors highly relevant to the prospects for a restart of nuclear power plant construction are the financial sector involved in financing nuclear power plant construction, the federal nuclear regulatory sector, and the national political sector. For this analysis, the general public are divided into two groups: those who are knowledgeable about and involved in nuclear power issues, the involved public, and the much larger body of the general public that is relatively uninvolved in the controversy over nuclear power

China’s Energy Transition in the Power and Transport Sectors from a Substitution Perspective

2017-04-01

Full Text Available Facing heavy air pollution, China needs to transition to a clean and sustainable energy system, especially in the power and transport sectors, which contribute the highest greenhouse gas (GHG emissions. The core of an energy transition is energy substitution and energy technology improvement. In this paper, we forecast the levelized cost of electricity (LCOE for power generation in 2030 in China. Cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles is also calculated in this study. The results indicate that solar photovoltaic (PV and wind power will be cost comparative in the future. New energy vehicles are more expensive than conventional vehicles due to their higher manufacturer suggested retail price (MSRP. The cost-emission effectiveness of the substitution between new energy vehicles and conventional vehicles would be $96.7/ton or $114.8/ton. Gasoline prices, taxes, and vehicle insurance will be good directions for policy implementation after the ending of subsidies.

2015-11-01

As France envisages to introduce a carbon floor price (raised from 8 to 30 euros) for the electricity sector like it has been the case in the UK since 2013, such a measure would not result in CO_2 emission reductions, but in emission transfers between actors. The authors comments and analyse the possible consequences of such a measure. By using the ZEPHYR model, they discuss the consequences on the European ETS and on the western European electric power market. They notably briefly comment the impact of a price of 30 euros per CO_2 ton on the emissions by the electricity sector in France, Germany, the UK and Poland, and more particularly of French emissions in 2013 and 2014

Emissions of sulfur dioxide (SO(2)) from the U.S. power sector decreased by 24% in 2009 relative to 2008. The Logarithmic Mean Divisia Index (LMDI) approach was applied to isolate the factors responsible for this decrease. It is concluded that 15% of the decrease can be attributed to the drop in demand for electricity triggered by the economic recession, and 28% can be attributed to switching of fuel from coal to gas responding to the decrease in prices for the latter. The largest factor in the decrease, close to 57%, resulted from an overall decline in emissions per unit of power generated from coal. This is attributed in part to selective idling of older, less efficient coal plants that generally do not incorporate technology for sulfur removal, and in part to continued investments by the power sector in removal equipment in response to the requirements limiting emissions imposed by the U.S. Environmental Protection Agency (U.S. EPA). The paper argues further that imposition of a modest tax on emissions of carbon would have ancillary benefits in terms of emissions of SO(2).

Full Text Available Renewable energy is an alternative resource to substitute fossil fuels. Currently, the share of renewable energy inpower generation is very low. The selected Greater Mekong Sub-region (GMS, namely, Cambodia, Laos, Thailand andVietnam is a region having abundant of renewable energy resources. Though these countries have a high potential of renewableenergy utilization, they are still highly dependent on the imported fossil fuels for electricity generation. The less contributionof renewable energy in the power sector in the region is due to the high cost of technologies. Renewable energytechnology cannot compete with the conventional power plant. However, in order to promote renewable energy utilizationand reduce dependency on imported fossil fuel as well as to mitigate CO2 emissions from the power sector, this study introducesfour renewable energy technologies, namely, biomass, wind, solar PV, and geothermal power, for substitution of conventionaltechnologies. To make the renewable energy competitive to the fossil fuels, incentives in terms of carbon credit of20$/ton-ne CO2 are taken into account. Results are analyzed by using the Long-Range Energy Alternative Planning System(LEAP modeling. Results of analyses reveal that in the renewable energy (RE scenario the biomass power, wind, solarphotovoltaics, and geothermal would contribute in electricity supply for 5.47 GW in the region, accounted for 3.5% in 2030.The RE scenario with carbon credits could mitigate CO2 emissions at about 36.0 million tonne at lower system cost whencompared to the business-as-usual scenario.

Specifics of the employment process in the public sector

2012-06-01

Full Text Available The labour legislation applicable in public sector is very different from the one applicable in private sector. Unlike the private sector where the market is the most efficient regulator and sanctions all errors made by the assessor, in the public sector there isn’t always a feed-back from the economic realities that may prove the accuracy and the efficiency of the assessment. Consequently, the law goes further on and imposes requirements, deadlines and procedures. While the private sector enjoys a certain flexibility regarding the assessment of the staff, in order to adjust it to the requirements of the economic realities, in the public sector, flexibility can lead to manifestations of subjectivism and arbitrariness. On the other hand, the excessive amount of regulations applicable in public sector may provide versatile and even contradictory results.

Does environmental regulation affect energy efficiency in China's thermal power generation? Empirical evidence from a slacks-based DEA model

International Nuclear Information System (INIS)

Bi, Gong-Bing; Song, Wen; Zhou, P.; Liang, Liang

2014-01-01

Data envelopment analysis (DEA) has gained much popularity in performance measurement of power industry. This paper presents a slack-based measure approach to investigating the relationship between fossil fuel consumption and the environmental regulation of China's thermal power generation. We first calculate the total-factor energy efficiency without considering environmental constraints. An environmental performance indicator is proposed through decomposing the total-factor energy efficiency. The proposed approach is then employed to examine whether environmental regulation affects the energy efficiency of China's thermal power generation. We find that the environmental efficiency plays a significant role in affecting energy performance of China's thermal generation sector. Decreasing the discharge of major pollutants can improve both energy performance and environmental efficiency. Besides, we also have three main findings: (1) The energy efficiency and environmental efficiency were relatively low. (2) The energy and environmental efficiency scores show great variations among provinces. (3) Both energy efficiency and environmental efficiency are of obvious geographical characteristics. According to our findings, we suggest some policy implications. - Highlights: • We assess the energy efficiency and the environmental efficiency of China's thermal power generation simultaneously. • The energy efficiency and the environmental efficiency were relatively low during 2007–2009. • The energy efficiency and environmental efficiency show obvious geographic characters. • The environmental performance of a DMU plays a decisive role in the energy performance

Frequency Regulation of a Hybrid Wind–Hydro Power Plant in an Isolated Power System

Full Text Available Currently, some small islands with high wind potential are trying to reduce the environmental and economic impact of fossil fuels by using renewable resources. Nevertheless, the characteristics of these renewable resources negatively affect the quality of the electrical energy, causing frequency disturbances, especially in isolated systems. In this study, the combined contribution to frequency regulation of variable speed wind turbines (VSWT and a pump storage hydropower plant (PSHP is analyzed. Different control strategies, using the kinetic energy stored in the VSWT, are studied: inertial, proportional, and their combination. In general, the gains of the VSWT controller for interconnected systems proposed in the literature are not adequate for isolated systems. Therefore, a methodology to adjust the controllers, based on exhaustive searches, is proposed for each of the control strategies. The control strategies and methodology have been applied to a hybrid wind–hydro power plant on El Hierro Island in the Canary archipelago. At present, in this isolated power system, frequency regulation is only provided by the PSHP and diesel generators. The improvements in the quality of frequency regulation, including the VSWT contribution, have been proven based on simulating different events related to wind speed, or variations in the power demand.

Decarbonising the power sector via technological change – differing contributions from heterogeneous firms

International Nuclear Information System (INIS)

Schmidt, Tobias S.; Schneider, Malte; Hoffmann, Volker H.

2012-01-01

In the power sector, technological change is a key lever to address the decarbonisation needed to avoid dangerous climate change. Policy makers aim to accelerate and redirect technological change by targeting relevant firms via climate policy, e.g., the European Union Emissions Trading System (EU ETS), and climate-relevant technology policies, e.g., feed-in tariffs. Changes in firm's behaviour, i.e., their research and development (R and D) as well as diffusion activities, are at the heart of technological change. However, firms are heterogeneous actors with varying attributes which perceive policy differently. Hence, they can be expected to react very heterogeneously to these new policies. Based on an original dataset of 201 firms, we perform a cluster analysis grouping firms along their R and D and diffusion activity changes. We then compare these clusters with regards to the characteristics of the contained firms. Our analysis results in seven clusters showing very diverse contributions to low-carbon technological change, suggesting potential for policy to become more effective. A comparison of the firms' characteristics allows us to derive indicative recommendations on how to adjust the policy mix in order to induce contributions from most firms in the power sector. - Highlights: ► Firms differ strongly regarding their contribution low-carbon technological change. ► E.g., about 40% of the surveyed firms have not changed their R and D and diffusion activities. ► These observations cast doubt upon the effectiveness of current policy. ► From the findings recommendations for making policy more effective are derived.

Regulation and market power in the Spanish liquefied petroleum gas industry: Progress or failure?

International Nuclear Information System (INIS)

Bello, Alejandro; Huerta, Emilio

2007-01-01

This paper presents a detailed study of the structure, market power and competition in the distribution sector for liquefied petroleum gas (LPG), within Spain. It is a segment of energy consumption and supply that is not often given serious attention, despite the fact that LPG is a crucial source of energy to many households, in many countries in Europe and in the rest of the world. Despite formally being an open and liberalized sector, the Spanish LPG market is characterized by high concentration within the industry; Repsol Butano, the dominant operator, practically controls the entire value chain. These structural characteristics probably justify state intervention in the form of price fixing, in order to guarantee accessible prices for final consumers. Nevertheless, applying this tool has had negative effects on the opening and liberalization process. On the one hand, it fails to encourage entry or an increase in the participation of new operators; on the other, it has considerably deteriorated the economic and financial performance of the distribution agents that are subjected to two strong forces. First, the dominant operator looks after its own interests and its income; and second, the Government tries to defend the interests of final consumers by fixing prices that inadequately remunerate the activity. This shows the contradictory regulatory actions that try to promote competition, and then establish mechanisms to regulate activity by fixing prices that act as price limits. These government set prices discourage new competitors from entering. (author)

Knops, H.P.A.

2002-01-01

This article analyses the use of the formula RPI - X (in Dutch: cpi - x) in the regulation of the Dutch energy sector. This issue has become current since the Trade and Industry Appeals Tribunal (College van Beroep voor het bedrijfsleven) ruled that the way in which the X was determined for the electricity supply tariffs for captive customers, did not comply with the 1998 Electricity Act. First, it is discussed what scheme the legislator envisaged concerning RPI - X in the 1998 Electricity Act and the Gas Act. Second, the practice of the RPI -X regulation is set out and its divergence from the legislator's intentions explained. Third, the decision of the Trade and Industry Appeals Tribunal and its consequences are described. Fourth, the proposed repair measures are discussed. To conclude, a final analysis of the Dutch RPI - X case, and some suggestions for its future will be given [nl

Michaud, Claude; Baudier, François

2007-01-01

Conflicts of interest between the food industry and public decision makers have increasingly multiplied over the last few years, especially within the context of implementing the French National Nutrition Programme. This paper describes the rhetoric and the strategies developed by the private sector in order to counter the law's implementation and enforcement based on a concrete example, namely, the removal of vending machines from schools. After having evoked possibilities of developing new partnerships as suggested by national and international health authorities, it reaffirms the right and the duty of the State to regulate within the framework of a health promotion policy, an approach which integrates the necessary open democratic public debate between the different sectors.

Combined heat and power in the Swedish district heating sector-impact of green certificates and CO2 trading on new investments

Knutsson, David; Werner, Sven; Ahlgren, Erik O.

2006-01-01

Combined heat and power (CHP) has been identified by the EU administration as an important means of reducing CO 2 -emissions and increasing the energy efficiency. In Sweden, only about one third of the demand for district heat (DH) is supplied from CHP. This share could be significantly larger if the profitability of CHP generation increased. The objective of this study was to analyse the extent to which the profitability for investments in new CHP plants in the Swedish DH sector have changed thanks to the recently implemented trading schemes for green certificates (TGCs) and CO 2 emissions (TEPs). The analysis was carried out using a simulation model of the Swedish DH sector in which the profitability of CHP investments for all DH systems, with and without the two trading schemes applied, is compared. In addition, a comparison was made of the changes in CHP generation, CO 2 emissions, and operation costs if investments are made in the CHP plant shown to be most profitable in each system according to the model. The study shows that the profitability of investments in CHP plants increased significantly with the introductions of TGC and TEP schemes. If all DH utilities also undertook their most profitable CHP investments, the results indicate a major increase in power generation which, in turn, would reduce the CO 2 emissions from the European power sector by up to 13 Mton/year, assuming that coal condensing power is displaced

A Sectoral Micro-Economic Approach to Scenario Selection and Development: The Case of the Greek Power Sector

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Generating policy-relevant scenarios is instrumental for understanding and developing policy measures. These are especially relevant to the power sector. Practitioners have been working on policy-relevant scenarios for the ex-ante assessment of policy measures in a meaningful way for end-users related to climate change mitigation and adaptation strategies. This paper presents a method for generating such policy relevant scenarios by focusing on the actor-contingent elements of the scenarios, i.e., the developments that are within the control of system actors to change or bring about. Several scenario techniques focusing on systematic-formalized or quantitative approaches have been published on this front over the past few years. Here, we introduce a methodology that is best suited for the assessment of the expected effect of different policy measures on the involved stakeholders’ behavior as well as for the analysis of the interactions between different policy measures as reflected on their impact on the strength and direction of the provided incentives. The applicability of our methodology is demonstrated for the case of the Greek power market. It was further evaluated in view of the challenges related to the issues of generation capacity adequacy and increased fiscal deficit. The strategic implications of the proposed approach concern the demonstration of the benefits from adopting a policy assessment methodology that focus on stakeholder expectations and interactions.

When the PWR are an important part of the power installed on a network, and that will be the case of the EDF network in the coming years, the participation of those plants to the power regulating becomes a necessity for the operating staff. This load regulating includes: daily variations of high amplitude; a permanent frequency - power regulating. The first part of the communication shows the network exploitation principles, and the resulting power variations concerning the existing nuclear power plants. Such transients are leading to stresses on fuel. The second part of the communication reports about the test program engaged by EDF in collaboration with the CEA and FRAMATOME, in order to study the fuel behaviour in real power conditions and power cycles, and that, just to the operational burn up of this fuel.

Regulator's role in sustainability of nuclear power

International Nuclear Information System (INIS)

Bansal, Parikshat; Sinha, Soumen; Bhattacharya, Ramdas

2015-01-01

A development which is environmentally benign, economically viable as well socially acceptable is regarded as sustainable development. Nuclear power scores extremely well with the first two parameters: i.e its cost of production is competitive with that of other power sources and is considered a clean source of power as the greenhouse gas emissions and discharge of other hazardous pollutants are insignificant. However, when it comes to acceptability by the society at large, there are issues. Early shutting down of power plants like Superphénix at France, abandonment of Yucca mountain project, agitation during commissioning of KKNPP etc. are few examples where the public perception was the main reason for such actions. These events tell us about the importance of public perception in sustainability of a project or nuclear power as a whole. In this backdrop, the role of regulator to present the safety aspects in correct perspective assumes enormous significance and goes in a long way in clearing unwarranted apprehensions, thereby playing a pivotal role in sustainability of nuclear power. The nuclear regulator needs to build long lasting trust and confidence with stakeholders. Therefore it needs to be continuously in touch with public, not only during crisis but also during peace time, disseminating information on safe use of ionizing radiation and atomic energy without undue risk to the health of the people and environment.

Integrated resource planning in the power sector and economy-wide changes in environmental emissions

International Nuclear Information System (INIS)

Shrestha, Ram M.; Marpaung, Charles O.P.

2006-01-01

This paper analyzes the roles of key factors (i.e., changes in structure, fuel mix and final demand) on total economy-wide changes in CO 2 , SO 2 and NO x emissions when power sector development follows the integrated resource planning (IRP) approach instead of traditional supply-based electricity planning (TEP). It also considers the rebound effect (RE) of energy efficiency improvements in the demand side and analyzes the sensitivity of the results to variations in the values of the RE. A framework is developed to decompose the total economy-wide change in the emission of a pollutant into four major components, i.e., structural change-, fuel mix- , final demand- and joint-effects. The final demand effect is further decomposed into three categories, i.e., construction of power plants, electricity final demand and final demand related to electricity using equipments. The factor decomposition framework is then applied in the case of the power sector in Indonesia. A key finding in the case of Indonesia is that in the absence of the RE, there would be total economy-wide reductions in CO 2 , SO 2 and NO x emissions of 431, 1.6 and 1.3 million tons respectively during the planning horizon of 2006-2025 under IRP as compared to that under TEP. The decomposition analysis shows that the final demand effect would account for 38% of the total CO 2 emission reduction followed by the structural change effect (35.1%) and fuel mix effect (27.6%) while the joint effect is negligible. The study also shows that economy-wide CO 2 emission reduction due to IRP considering the RE of 45% would be 241 million tons as compared to 333 million tons when the RE is 25%
