    This analysis uses a new method to link the NREL Regional Energy Deployment System (ReEDS) capacity expansion model with the NREL distributed generation market demand model (dGen) to explore the impact that the evolution of retail electricity tariffs can have on the adoption of distributed photovoltaics (DPV). The evolution most notably takes the form of decreased mid-day electricity costs, as low-cost PV reduces the marginal cost of electricity during those hours and the changes are subsequently communicated to electricity consumers through tariffs. We find that even under the low PV prices of the new SunShot targets the financial performance of DPV under evolved tariffs still motivates behind-the-meter adoption, despite significant reduction in the costs of electricity during afternoon periods driven by deployment of cheap utility-scale PV. The amount of DPV in 2050 in these low-cost futures ranged from 206 GW to 263 GW, a 13-fold and 16-fold increase over 2016 adoption levels respectively. From a utility planner's perspective, the representation of tariff evolution has noteworthy impacts on forecasted DPV adoption in scenarios with widespread time-of-use tariffs. Scenarios that projected adoption under a portfolio of time-of-use tariffs, but did not represent the evolution of those tariffs, predicted up to 36 percent more DPV in 2050, compared to scenarios that did not represent that evolution. Lastly, we find that a reduction in DPV deployment resulting from evolved tariffs had a negligible impact on the total generation from PV - both utility-scale and distributed - in the scenarios we examined. Any reduction in DPV generation was replaced with utility-scale PV generation, to arrive at the quantity that makes up the least-cost portfolio.

  3. Impact of Large Scale Energy Efficiency Programs On Consumer Tariffs and Utility Finances in India

    Large-scale EE programs would modestly increase tariffs but reduce consumers' electricity bills significantly. However, the primary benefit of EE programs is a significant reduction in power shortages, which might make these programs politically acceptable even if tariffs increase. To increase political support, utilities could pursue programs that would result in minimal tariff increases. This can be achieved in four ways: (a) focus only on low-cost programs (such as replacing electric water heaters with gas water heaters); (b) sell power conserved through the EE program to the market at a price higher than the cost of peak power purchase; (c) focus on programs where a partial utility subsidy of incremental capital cost might work and (d) increase the number of participant consumers by offering a basket of EE programs to fit all consumer subcategories and tariff tiers. Large scale EE programs can result in consistently negative cash flows and significantly erode the utility's overall profitability. In case the utility is facing shortages, the cash flow is very sensitive to the marginal tariff of the unmet demand. This will have an important bearing on the choice of EE programs in Indian states where low-paying rural and agricultural consumers form the majority of the unmet demand. These findings clearly call for a flexible, sustainable solution to the cash-flow management issue. One option is to include a mechanism like FAC in the utility incentive mechanism. Another sustainable solution might be to have the net program cost and revenue loss built into utility's revenue requirement and thus into consumer tariffs up front. However, the latter approach requires institutionalization of EE as a resource. The utility incentive mechanisms would be able to address the utility disincentive of forgone long-run return but have a minor impact on consumer benefits. Fundamentally, providing incentives for EE programs to make them comparable to supply

    2014-01-01

    The policy reform literature is primarily concerned with the construction of reforms that yield welfare gains. By contrast, this paper’s contribution is to develop a theoretical concept for which the focus is upon the sizes of welfare gains accruing from policy reforms rather than upon their signs....... In undertaking this task, and by focusing on tariff reforms, we introduce the concept of a steepest ascent policy reform, which is a locally optimal reform in the sense that it achieves the highest marginal gain in utility of any feasible local reform. We argue that this reform presents itself as a natural...... benchmark for the evaluation of the welfare effectiveness of other popular tariff reforms such as the proportional tariff reduction and the concertina rules, since it provides the maximal welfare gain of all possible local reforms. We derive properties of the steepest ascent tariff reform, construct...

  6. Tariffs Ranking in Mixed Oligopoly with Revenue Constraint

    2011-01-01

    Full Text Available Utilizing linear mixed oligopoly model, this paper explores the magnitude of the maximum-revenue tariff, optimum-welfare tariff, and revenue-constrained optimal tariff that is especially designed for the consideration of the bureaucratic inefficiency. In particular, the tariff ranking issue is examined under both cases of Cournot competition and domestic public leadership. We found that, under Cournot competition, the optimum-welfare tariff is the highest and it is followed by the revenue-constrained optimal tariff while the maximum-revenue tariff is the lowest. But, under Stackelberg public leadership, if the domestic private firms are fewer than the foreign firms, the maximum-revenue tariff becomes the highest and the optimum-welfare exceeds the revenue-constrained optimal tariff.

  7. WTO Agricultural Tariffication with Lessons for Tariff Adoption

    Full Text Available According to the Uruguay Round Agreement on Agriculture (URAA, all agricultural non-tariff trade barriers should be converted into equivalent tariffs and further, reduced over time. However each member country has the authority to choose the tariff types when it converts NTBs to tariffs such as ad valorem tariff and specific tariff. The paper tries to find the reason for the choice of a certain type of tariff in the process of tariffication after the UR negotiation on agriculture. To achieve this goal, the paper analyses the effects of tariffication of a fixed quota into tariffs on price, trade and welfare in a number of scenarios related to the sources of uncertainty. In this paper, we examine the nonequivalence of specific tariff and ad valorem tariff, which are general type of tariffs used in the most of countries. The paper has shown that the two types of tariffs selected by tariffication of import quota are not generally equivalent in both their effects on price and trade stability and welfare with the trade model under uncertainty. The main conclusion of this study is that there is no general presumption that one tariff regime is superior to the other tariff regime under conditions of uncertainty. The precise source of uncertainty and the properties of the relevant demand and supply functions might affect the determination of tariff type selected after tariffication of non-tariff barriers.

    Recent rounds of GATT and later WTO have advocated widespread tariffication, meaning that existing non-tariff barriers be converted into import equivalent tariffs. From an economic point of view, the effects of such tariffication are not entirely clear. The paper presents a general equilibrium model with monopolistic competition to examine the welfare effects of tariffication. The ranking of pre- and post-tariffication welfare depends crucially on the nature of the initial trade barrier and t...

  9. Dynamically consistent oil import tariffs

    International Nuclear Information System (INIS)

    Karp, L.; Newbery, D.M.

    1992-01-01

    The standard theory of optimal tariffs considers tariffs on perishable goods produced abroad under static conditions, in which tariffs affect prices only in that period. Oil and other exhaustable resources do not fit this model, for current tariffs affect the amount of oil imported, which will affect the remaining stock and hence its future price. The problem of choosing a dynamically consistent oil import tariff when suppliers are competitive but importers have market power is considered. The open-loop Nash tariff is solved for the standard competitive case in which the oil price is arbitraged, and it was found that the resulting tariff rises at the rate of interest. This tariff was found to have an equilibrium that in general is dynamically inconsistent. Nevertheless, it is shown that necessary and sufficient conditions exist under which the tariff satisfies the weaker condition of time consistency. A dynamically consistent tariff is obtained by assuming that all agents condition their current decisions on the remaining stock of the resource, in contrast to open-loop strategies. For the natural case in which all agents choose their actions simultaneously in each period, the dynamically consistent tariff was characterized, and found to differ markedly from the time-inconsistent open-loop tariff. It was shown that if importers do not have overwhelming market power, then the time path of the world price is insensitive to the ability to commit, as is the level of wealth achieved by the importer. 26 refs., 4 figs

    A tariff on U.S. oil imports is justified by the special characteristics of oil and oil markets. Unlike other commodities, oil production and prices have been manipulated successfully by foreign producers for protracted periods. Moreover, unlike most other products, the price and availability of oil significantly affect macro-economic variables such as our trade balance, the rate of inflation, and the aggregate level of economic activity. And, more than most commodities, oil is crucial to our national security. For these reasons, the full cost of U.S. oil imports is not reflected in the price we pay in the world market. The gap between the true cost of oil to the nation and the market price justifies imposition of an offsetting tariff. Beleagured domestic oil producers have called for a tariff on imported petroleum supplies. Such a protectionist measure would, in effect, provide them with price guarantees in the face of soft market conditions. Behind the producers' argument is the belief that world oil prices will remain low for a sustained period of time and that, as a result, there will be an appreciable decline in U.S. exploration, development, and production activity, posing a major threat to the future viability of the U.S. oil industry.

    This article discusses the tariff regulation models adopted in the electricity utility sector, with a focus on the innovations introduced as a result of the liberalization of the sector that began in the 1980s. The principal tariff criteria are discussed: tariffs determined by the both the rate of return regulation and by marginal cost, and price-caps. Instruments complementary to tariffs are also examined. The main aim of the article is to contribute to a better understanding of the tariff rules adopted in the electricity sector. (author)

  15. Reforming residential electricity tariff in China: Block tariffs pricing approach

    International Nuclear Information System (INIS)

    Sun, Chuanwang; Lin, Boqiang

    2013-01-01

    The Chinese households that make up approximately a quarter of world households are facing a residential power tariff reform in which a rising block tariff structure will be implemented, and this tariff mechanism is widely used around the world. The basic principle of the structure is to assign a higher price for higher income consumers with low price elasticity of power demand. To capture the non-linear effects of price and income on elasticities, we set up a translog demand model. The empirical findings indicate that the higher income consumers are less sensitive than those with lower income to price changes. We further put forward three proposals of Chinese residential electricity tariffs. Compared to a flat tariff, the reasonable block tariff structure generates more efficient allocation of cross-subsidies, better incentives for raising the efficiency of electricity usage and reducing emissions from power generation, which also supports the living standards of low income households. - Highlights: • We design a rising block tariff structure of residential electricity in China. • We set up a translog demand model to find the non-linear effects on elasticities. • The higher income groups are less sensitive to price changes. • Block tariff structure generates more efficient allocation of cross-subsidies. • Block tariff structure supports the living standards of low income households

  16. The Haitian Rice Tariff

    Full Text Available Se ha argumentado que los problemas agríco-las de Haití derivan de la tarifa del arroz de a mediados de los años noventa. Antes, supues-tamente, Haití fue autosuficiente, abastecida por su producción doméstica. Después de la reducción, el mercado haitiano se inundó en importaciones de arroz barato de los EEUU, lo cual despojó a los campesinos de sus fincas, convirtiendolos en migrantes internos, hacia los empleos de bajo pago de las ciudades. El artículo rechaza ese argumento y demuestra que es falso. La malnutrición fue un fenómeno extendido en Haití mucho antes de la reducción de la tarifa del arroz, la cual tampoco tuvo un gran impacto en la importación y la producción doméstica del arroz. Lo que sí impulsó el aumento de las importaciones fue el crecimiento de la población. También el artículo argumenta que un aumento de la tarifa del arroz no solucionará el problema de la alimentación que sufre Haití. English: It has been argued that Haiti’s agricultural problems derive from the reduction of the rice tariff in the mid-1990s. Before that Haiti was allegedly able to meet its food needs by domestic production. After the reduction the Haitian market was swamped by imports of cheap American rice which drove the farmers off their lands and forced them to migrate to low-wage industrial jobs in the cities. The article demonstrates that the argument is false. Malnutrition was widespread in Haiti long before the rice tariff reduction, and the latter did not have much of an impact on rice imports and domestic production. Instead, the main driving force behind imports appears to be population growth. It is also shown that an increase of the rice tariff will not solve Haiti’s food problem.

    Latvia has only a few indigenous energy resources that are concentrated on hydro-power, wood and peat. The country is therefore strongly dependant on imports of natural gas, oil, coal and electricity. After independence the supply of natural gas, oil and electricity were organised by three state owned joint-stock companies, Latvijas Gaze, Latvijas Nafta and Latvenergo. Partial privatisation of the gas and oil companies has been decided by the Latvian government but so far not implemented. Two types of models have been used within the Energy Tariff Project: The EFOM model that was developed and implemented for Latvia as a part of the EURIO project has been adapted to describe the long term reactions for the electricity and district heating sectors; A system of Customer Calculation Sheets for the analysis of consumer expenditure and utility revenue. The optimization model for the electricity and CHP system is also used to analyze the impact of gas tariffs for the electricity and district heating sector within geographical or institutional limits. In this report the following regions are specified: City of Riga; Other district heating areas; Rest of Latvia. The Danish tariff structure for natural gas was reviewed. The present structure is presently market orientated with direct links to the price movements of alternative fuels for all customer groups. (EG) 50 refs

    At the time of the debates about the French 'NOME' (new organization of the electricity market) law, it is interesting to analyse the principles which have led to elaborate the 'historical' electricity tariffs in France, in order to better understand the stakes around their recasting. Today, there exists 2 categories of tariffs: the regulated selling prices and the market offers. The regulated selling prices are different depending on the client (individuals, small professionals, companies)

    Seasonal prevailing surface winds are analyzed in the territory of Northern Serbia, using observational data from 12 meteorological stations over several decades. In accordance with the general definition of prevailing wind, two special definitions of this term are used. The seasonal wind roses in 16 directions at each station are analyzed. This study shows that the prevailing winds in Northern Serbia have northwestern and southeastern directions. Circulation weather types over Serbia are presented in order to determine the connections between the synoptic circulations and prevailing surface winds. Three controlling pressure centers, i.e., the Mediterranean cyclone, Siberian high, and the Azores anticyclone, appear as the most important large-scale factors that influence the creation of the prevailing winds over Northern Serbia. Beside the synoptic cause of the prevailing winds, it is noted that the orography of the eastern Balkans has a major influence on the winds from the second quadrant. It was found that the frequencies of circulation weather types are in agreement with those of the prevailing winds over Northern Serbia.

    Guillelmon, B.

    1995-01-01

    The tariff increase of BKW Energie AG in October 1994 was, seen as a chance to review the tariff structure. First of all, the different products delivered to the customers were clearly defined, according to the following criteria: quantity of electricity intake at high tariff, degree of freedom at intake as well as supply and measurement point of the intake. In a second step the objectives to be fulfilled with the new structure were set: the tariffs should be customer-friendly easy to understand and to apply, foreseeable, cost-related as well as take into account the new findings in energy economics and finally give the right signals for a sparing use of natural resources. Some more considerations, especially on the allocation of the demand costs on demand and consumption rates were made. The new tariffs of BKW offer more flexibility and choices for the customers: retail customers can choose between single and two-rate tariffs. Moreover, they can choose a tariff for interruptable intake as a supplementary subscription. Big customers can choose among different options according to the utilisation time. The setting up of clear names and good information as well as specific offer of energy advice to the customers at the moment of the tariff increase were considered as highly valuable. The new tariff structure is one step in the right direction. The structure must still be ameliorated in the future. The trend will possibly be in a higher differentiation of tariffs for big customers and a high valuation of simplicity for the tariffs for retail customers. (author)

    Yu, Wang; Sheble, Gerald B.; Lopes, Joao A. Pecas; Matos, Manuel Antonio

    2006-01-01

    The current fixed tariff remuneration for wind energy is not compatible with the deregulation of the electric power industry. The time-varying and location-dependent value of renewable energy is not acknowledged. The newly announced switchable tariff for wind energy in the Spanish electricity market provides a promising solution to compensating renewable energy within the deregulated electric power industry. The new switchable tariff provides wind generators more flexibility in operating wind generation assets. Such flexibilities provide option value in coordinating the seasonality of wind energy, demand on electric power and electricity prices movement. This paper models and valuates the flexibility on switching tariff as real compound options for wind generators. Numerical examples valuate wind generation assets under fixed tariff, spot market price taking, and yearly and monthly switchable tariffs. The optimal switching strategies are identified. The impacts of the switchable tariff on sitting criteria and values of wind generation assets are investigated. An improvement on the yearly switchable tariff is suggested to further reduce the operation risk of wind generators and fully explore the efficiency provided by competitive electricity markets.

  6. Determinants of green electricity tariff uptake in the UK

    MacPherson, Ronnie; Lange, Ian

    2013-01-01

    A number of countries offer domestic consumers the option of buying their electricity supply through a ‘green tariff’, whereby the supplier typically guarantees that all or part of the supply has been generated using renewable energy sources. Previous studies that have sought to identify variables predicting why consumers choose to purchase a green tariff have utilized surveys specifically about the topic. This study builds on previous work by reviewing the UK market using data from the Understanding Society Survey, a general survey of households which should be free from framing or focalism concerns. In addition, this data includes variables that – to the authors’ knowledge – have not been tested through other work. Results find that individuals in the highest income quartile, those with higher qualifications, those supporting the Green political party, and those exhibiting strong environmental behaviour were all more likely to have purchased green tariffs. Significant to a lesser degree were strong environmental attitudes and those households with some form of renewable energy technology installed. -- Highlights: •Model consumer determinants of the uptake of green tariffs. •Utilize behavioural as well as demographic variables to explain outcome. •Highest income quartile and green behaviours most correlated with outcome

    Full Text Available Distortionary levy applied uniformly to all diameter classes of logs from logging natural forest can lead to inefficiencies; certain diameter should be left in the field because it is not economical to be used. Win-win or Pareto improving solution can be achieved if the government is more flexible. Social welfare is higher because of the waste that can be utilized to create employment, production and additional benefits for employers, as well as revenue for the state. Even if the levy rates are forced to zero for small-diameter timber, governments is actually not harmed at all because from the beginning the government does not get any revenue from small timber that is left in the field as waste. In scarcity situations of timber from natural forests, it is desirable if the government is considering differentiating charges in order to reduce or possibly eliminate the volume of waste generated by the levy. In general, tariff differentiation done in the form of higher tariffs for higher diameter logs. If possible, the lowest diameter limit of logs is forced down to its technical limits. That is, the processing tool that will determine how the minimum diameter logs can be processed profitably.Keywords: tariff differentiation, efficiency, timber utilization, government revenue, win-win solutionDOI: 10.7226/jtfm.19.2.163

  8. International perspectives on the importance of electric tariff transitioning to cost-based levels in Bulgaria

    International Nuclear Information System (INIS)

    Simpson, T.; Davis, F.; Dilovska, I.

    1996-01-01

    The traditional cost-of-service approach to power pricing has been replaced in many countries by market pricing mechanisms that compensate power producers at the marginal cost of production established collectively in the marketplace. The paper stresses the importance of cost-based tariff setting pointing out two main pricing principles of utility services: 1) Revenues must meet or exceed the utility average cost of production; 2) Marginal cost pricing for incremental consumption must ensure efficient allocation of resources. Examples describing the factors encouraging transition to economically efficient tariffs at a small utility are given for: Northwest U.S., MINENERGO in Belarus, Pacific Gas and Electric Co in California and the National Electric Co (NEK) in Bulgaria.The analysis of the Bulgarian electric sector is based on ongoing work being funded by the U.S. Agency for International Development. Each of the four utilities described faces a different challenge for transitioning tariffs to cost- based levels. However, one and the same broad conclusion applies in all cases: utility pricing must take into account the underlying average and marginal cost structures of the regional power industry. Bulgaria needs transition to cost-based tariffs to recover the electricity cost-of-service and to ensure that the electric sector operates efficiently and consumers are treated fairly. Measures that facilitate the process of tariff transitioning include: 1) Developing a transparent process of tariff setting with clear objectives, a plan and timetable, and roles of organizations; 2) Establishing of independent regulation to ensure that tariff setting objectives are achieved; 3) Instituting mechanisms to reward organizations for performance that achieves electric sector objectives. 3 figs

  9. Exploring the impact of network tariffs on household electricity expenditures using load profiles and socio-economic characteristics

    2018-04-01

    Growing self-generation and storage are expected to cause significant changes in residential electricity utilization patterns. Commonly applied volumetric network tariffs may induce imbalance between different groups of households and their respective contribution to recovering the operating costs of the grid. Understanding consumer behaviour and appliance usage together with socio-economic factors can help regulatory authorities to adapt network tariffs to new circumstances in a fair way. Here, we assess the effects of 11 network tariff scenarios on household budgets using real load profiles from 765 households. Thus we explore the possibly disruptive impact of applying peak-load-based tariffs on the budgets of households when they have been mainly charged for consumed volumes before. Our analysis estimates the change in household network expenditure for different combinations of energy, peak and fixed charges, and can help to design tariffs that recover the costs needed for the sustainable operation of the grid.

    Designing a desirable increasing block tariff for the residential gas retail market has been a challenging task for regulated utilities, especially in China. To deal with such problems, in this paper, we establish an agent-based, computational economics system to provide a formal evaluation of the direct and indirect influences of several issued increasing block tariffs in the residential gas market. Moreover, a comprehensive demand response behaviour model has been improved in term of price elasticity, while still coping with income levels and complex social environment. We also compute and compare the outcomes of several increasing block tariffs with the initial flat tariff by running the system on a test-case using real-world data from a middle-scale gas retail market in Wuhan. The results indicate that there is an appropriate increasing block gas tariff scheme that has greater ability to improve social equity while still ensuring operator revenue and promoting gas conservation. In order to offset the limitations of the proposed increasing block tariffs, the regulator should adopt some complementary measures, such as applying appropriate policies targeting the intended consumers, and allowing large families to obtain extra allowance of volume. - Highlights: •Analyse the influence of increasing block tariffs in residential gas sector. •An agent-based computational economics system is utilised for policy analysis. •Increasing block tariff can generate revenue while still promote gas conservation. •The increasing subsidy for low income household can improve the social equity.

    While an export tariff is only one element of a larger regulatory framework for distributed generation, we choose to focus on tariff design because of the significant impact this program design component has on the various flows of value among power sector stakeholders. In that context, this paper is organized into a series of steps that can be taken during the design of a DGPV export tariff design. To that end this paper outlines a holistic, high-level approach to the complex undertaking of DGPV tariff design, the crux of which is an iterative cost-benefit analysis process. We propose a multi-step progression that aims to promote transparent, focused, and informed dialogue on CBA study methodologies and assumptions. When studies are completed, the long-run marginal avoided cost of the DGPV program should be compared against the costs imposed on utilities and non-participating customers, recognizing that these can be defined differently depending on program objectives. The results of this comparison can then be weighed against other program objectives to formulate tariff options. Potential changes to tariff structures can be iteratively fed back into established analytical tools to inform further discussions.

  15. Pricing of electricity tariffs in competitive markets

    In many countries electricity supply business has been opened for competition. In this paper we analyze the problem of pricing of electricity tariffs in these open markets, when both the customers' electricity consumption and the market price are stochastic processes. Specifically, we focus on regular tariff contracts which do not have explicit amounts of consumption units defined in the contracts. Therefore the valuation process of these contracts differs from the valuation of electricity futures and options. The results show that the more there is uncertainty about the customer's consumption, the higher the fixed charge of the tariff contract should be. Finally, we analyze the indication of our results to the different methods for estimating the customer's consumption in the competitive markets. Since the consumption uncertainties enter into the tariff prices, the analysis indicates that the deterministic standard load curves do not provide efficient methods for evaluating the customers' consumption in competitive markets

    In the absence of an international environmental agreement (IEA) on climate change, a country may be reluctant to unilaterally implement environmental actions, as this may lead to the relocation of firms to other, lax-on-pollution countries. To avoid this problem, while still taking care of the environment, a country may impose a carbon tariff that adjusts for the differences between its own carbon tax and the other country's tax. We consider two countries with a representative firm in each one, and characterize and contrast the equilibrium strategies and outcomes in three scenarios. In the first (benchmark) scenario, in a first stage the regulators in the two countries determine the carbon taxes noncooperatively, and in a second stage, the firms compete à la Cournot. In the second scenario, the regulators cooperate in determining the carbon taxes, while the firms still play a noncooperative Cournot game. In the third scenario, we add another player, e.g., the World Trade Organization, which announced a border tax in a prior stage; the game is then played as in the first scenario. Our two major results are (i) a border-tax adjustment (BTA) mimics quite well the cooperative solution in setting the carbon taxes as in scenario two. This means that a BTA may be a way around the lack of enthusiasm for an IEA. (ii) All of our simulations show that a partial correction of the difference in taxes is sufficient to maximize total welfare. In short, the conclusion is that a BTA may be used as a credible threat to achieve an outcome that is very close to the cooperative outcome. - Highlights: • One of the first studies to consider border-tax adjustment in a strategic context. • Border-tax adjustment can lead to an optimal outcome, in cooperative sense. • Optimal outcome is achieved with partial tax adjustment

  18. Tariffs and Firm-Level Heterogeneous Fixed Export Costs

    DEFF Research Database (Denmark)

    Schröder, Philipp J.H.; Jørgensen, Jan Guldager

    2006-01-01

    This paper presents a two country intra-industry trade model with bilateral ad valorem tariffs and fixed export costs that are heterogeneous across firms. In this model not all firms will choose to export. We examine the effects of reciprocal changes in the tariff and the fixed export barrier...... on the number of firms, firm profits, tariff revenue and consumer welfare. We show that both types of trade barriers reduce (increase) the number of exporting (pure domestic) firms. However, the sum of available home and foreign varieties may actually increase for small tariffs. Firm profits fall for both...... the tariff and the fixed export barrier. Tariff revenue falls for an increase in fixed exporting costs whereas we have a Laffer curve effect for the tariff. Finally, we establish that welfare falls with fixed export costs and large tariffs but increases for small tariffs, i.e. there exist a welfare...

    2013-07-01

    This document reports an audit study performed by the ADEME and related to energy social tariffs, to their modalities and distribution costs, and aimed at proposing recommendations to improve these arrangements or to create a new one. In a first part, it outlines that these tariffs are apparently based on simple and fair principles, describes how eligible households are identified, outlines that these tariffs do not solve arrangement structural inequity between heating modes, that the awarded amount depends on too many parameters, that providers are totally reimbursed (sometimes even more), and that the arrangement is still insufficient to solve the problem of energy poverty. The second part addresses operational modalities and highlights their complexity. Recommendations are then stated which are aimed at consolidating and simplifying them, and at modifying them to create an actual energy shield

  20. Renewable Energy Prices in State-Level Feed-in Tariffs: Federal Law Constraints and Possible Solutions

    Energy Technology Data Exchange (ETDEWEB)

    Hempling, S.; Elefant, C.; Cory, K.; Porter, K.

    2010-01-01

    State legislatures and state utility commissions trying to attract renewable energy projects are considering feed-in tariffs, which obligate retail utilities to purchase electricity from renewable producers under standard arrangements specifying prices, terms, and conditions. The use of feed-in tariffs simplifies the purchase process, provides revenue certainty to generators, and reduces the cost of financing generating projects. However, some argue that federal law--including the Public Utility Regulatory Policies Act of 1978 (PURPA) and the Federal Power Act of 1935 (FPA)--constrain state-level feed-in tariffs. This report seeks to reduce the legal uncertainties for states contemplating feed-in tariffs by explaining the constraints imposed by federal statutes. It describes the federal constraints, identifies transaction categories that are free of those constraints, and offers ways for state and federal policymakers to interpret or modify existing law to remove or reduce these constraints. This report proposes ways to revise these federal statutes. It creates a broad working definition of a state-level feed-in tariff. Given this definition, this report concludes there are paths to non-preempted, state-level feed-in tariffs under current federal law.

    When Vietnam joined the World Trade Organization (WTO) in 2007 it was granted an accession period up to 2014. During this period tariffs would have to fall according to the accession agreement. This paper evaluates this 2007–2014 trade liberalization by building an applied general equilibrium model...... and calibrating it to the Vietnamese data. The model pays careful attention to the fact that Vietnam has many state-owned enterprises. The model simulations show that the WTO tariff reductions will reduce overall welfare. Moreover, the biggest loss will take place among the poor rural households in Vietnam...

  2. Cost-Causation-Based Tariffs for Wind Ancillary Service Impacts: Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Kirby, B.; Milligan, M.; Wan, Y.

    2006-06-01

    Conference paper discussing the integration cost of wind. Although specific tariffs for wind generation for ancillary services are uncommon, we anticipate that balancing authorities (control areas) and other entities will move toward such tariffs. Tariffs for regulation and imbalance services should be cost-based, recognize the relevant time scales that correspond with utility operational cycles, and properly allocate those costs to those entities that cause the balancing authority to incur the costs. In this paper, we present methods for separating wind's impact into regulation and load following (imbalance) time scales. We show that approximating these impacts with simpler methods can significantly distort cost causation and even cause confusion between the relevant time scales. We present results from NREL's wind data collection program to illustrate the dangers of linearly scaling wind resource data from small wind plants to approximate the wind resource data from large wind plants. Finally, we provide a framework for developing regulation and imbalance tariffs, we outline methods to begin examining contingency reserve requirements for wind plants, we provide guidance on the important characteristics to consider, and we provide hypothetical cases that the tariff can be tested against to determine whether the results are desired.

    The U. S. maple tariff is a tax on maple syrup and sugar imports from Canada into the United States. An analysis of the maple tariff indicates that it was never very effective in protecting the domestic maple industry from foreign competition. The tariff has been especially ineffective since World War II. Its removal will not hurt the U. S. maple syrup industry.

  10. Review of European regulatory and tariff experience with the sale of heat and electricity from combined heat and power plants

    International Nuclear Information System (INIS)

    Dyrelund, A.

    1991-12-01

    The Prince Edward Island Energy Corporation, Edmonton Power, Energy, Mines and Resources Canada and the Canadian Electrical Association commissioned a study to understand how electrical power and district heat from combined heat and power (CHP) plants is priced in Europe. Four northern European countries were investigated, Denmark, Germany, Sweden and Finland. These countries produce 45.8 TWh of power from combined heat and power plants, 7.1% of their annual consumption. In the case of Denmark, CHP accounts for 37.5% of its total power production. The energy situation in each country is reviewed using published statistics, and in particular the rapidly changing situation with regard to environmental and fuel taxes is examined. In order to obtain practical insights with regard to tariffs used by the various utilities, a series of generic examples were examined, supported by specific case studies. Technologies reviewed included: CHP from coal-fuelled extraction plant, CHP from coal-fuelled back pressure plant, waste heat from a municipal waste plant, and gas turbine with waste heat recovery. The benefits and risks associated with different tariff designs are discussed in detail including tariff formulae. This should enable interested parties to develop appropriate tariffs for combined heat and power plants in the context of current electrical utility policies. As a complement to the tariffs for combined heat and power plants, the design of district heating tariffs is also addressed. The typical concepts used in different countries are presented and discussed. 23 tabs

    Electricity regulators are facing new challenges to keep the pace of the liberalization process and the revision of regulatory schemes that is taking place all over the world. The pressure is also felt by regulated activities such as distribution. One of the main objectives of this process is to improve efficiency. Electricity rates and more specifically distribution network tariffs should also be adapted to these new requirements. This paper describes the main rate design approaches that are used to recover distribution costs. Drawbacks of the current methods are highlighted, and a new tariff design methodology based on cost causality is presented. Efficiency achievement as well as compliance with legal and regulatory criteria, such as cost recovery and non-discrimination, is analyzed. (author)

    Marietta, K.E.; Achinger, S.K.

    1993-01-01

    In October of 1990, Northern States Power Company (NSP or Company), filed a unique open transmission tariff for both captive customers and through-system transactions. This is an important step towards expanding transmission services in the United States. Many individuals in the utility industry, who may be considering Imposing generation costs on transmission services, have been closely monitoring NSP's case which is currently before the Federal Energy Regulatory Commission (FERC). NSP's innovative generation costs include charges for reactive power production, frequency control, load dispatching, and load following. The results of this case may also have an important impact on the future of open transmission tariffs. Rates for these services depend on the customer's classification as either a captive or through-system consumer. The proposed tariff raises critical issues related to the costing of these transmission services. NSP's methodology has caused serious concern because the proposed tariff would increase transmission costs by an average of 53%. This paper will discuss the benefits of transmission, proposed rates, contract terms, and costing methodologies of NSP's plan

  18. Comparing the feed-in tariff incentives for renewable electricity in Ontario and Germany

    International Nuclear Information System (INIS)

    Mabee, Warren E.; Mannion, Justine; Carpenter, Tom

    2012-01-01

    The development of feed-in tariff (FIT) programs to support green electricity in Ontario (the Green Energy and Green Economy Act of 2009) and Germany (the Erneuerbare Energien-Gesetz of 2000) is compared. The two policies are highly comparable, offering similar rates for most renewable electricity technologies. Major differences between the policies include the level of differentiation found in the German policy, as well as the use of a price degression strategy for FIT rates in Germany compared to an escalation strategy in Ontario. The German renewable electricity portfolio is relatively balanced, compared to Ontario where wind power dominates the portfolio. At the federal level, Canada does not yet have a policy similar to the European Directive on Renewable Energy, and this lack may impact decisions taken by manufacturers of renewable technologies who consider establishing operations in the province. Ontario's Green Energy and Green Economy Act could be benefit from lessons in the German system, especially with regard to degression of feed-in tariff rates over time, which could significantly reduce payments to producers over the course of a contract, and in turn encourage greater competitiveness among renewable power providers in the future. - Highlights: ► We compare two jurisdictions that utilize feed-in tariffs to support renewable electricity. ► Complementary policy such as mandated renewable energy use in conjunction with tariffs increases certainty for investors. ► Targeted incentives in the form of adders can deliver more diversity in renewable generation capacity. ► Degression of tariff rates delivers renewable generation capacity at lower cost.

  19. Transmission tariffs based on optimal power flow

    International Nuclear Information System (INIS)

    Wangensteen, Ivar; Gjelsvik, Anders

    1998-01-01

    This report discusses transmission pricing as a means of obtaining optimal scheduling and dispatch in a power system. This optimality includes consumption as well as generation. The report concentrates on how prices can be used as signals towards operational decisions of market participants (generators, consumers). The main focus is on deregulated systems with open access to the network. The optimal power flow theory, with demand side modelling included, is briefly reviewed. It turns out that the marginal costs obtained from the optimal power flow gives the optimal transmission tariff for the particular load flow in case. There is also a correspondence between losses and optimal prices. Emphasis is on simple examples that demonstrate the connection between optimal power flow results and tariffs. Various cases, such as open access and single owner are discussed. A key result is that the location of the ''marketplace'' in the open access case does not influence the net economical result for any of the parties involved (generators, network owner, consumer). The optimal power flow is instantaneous, and in its standard form cannot deal with energy constrained systems that are coupled in time, such as hydropower systems with reservoirs. A simplified example of how the theory can be extended to such a system is discussed. An example of the influence of security constraints on prices is also given. 4 refs., 24 figs., 7 tabs

    2018-02-01

    The backwardness of the water utilities sector necessitates urgent investment in infrastructure to improve water quality and efficiency in water supply networks. A policy of tariff growth represents the main source to sustain such investments. Therefore, customer engagement in the form of willingness to pay (WTP) is highly desirable by water utilities to obtain social legitimization and support. This study examines the determinants of consumers' WTP for improvement programs for three drinking water issues: quality of water sources, renewal of water mains, and building of new wastewater treatment plants. The study is based on a survey conducted among a sample of 587 customers of a water utility located in the province of Verona in the north of Italy. The contingence valuation method is used to measure WTP. Specifically, an ordinal logistic regression model yields the following significant determinants of WTP: quality of water and services provided, preference for privatization of the water utility, sustainable consumption of water, and some socio-demographic variables. The findings provide interesting insights into the drivers of WTP as well as managerial recommendations for water utilities. In particular, the findings show that water utilities need to improve service and water quality to increase customers' acceptance of tariff growth. In addition, utilities should invest in customer education and communication activities focusing on specific age groups (e.g., older customers) to enhance their WTP. Finally, communication strategies should reinforce the possible role of liberalization and privatization in supporting infrastructure investments. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Hernandez, Alan; Hess, Daniel P.

    2016-01-01

    This paper presents results from tests to assess the use of anaerobic adhesive for providing a prevailing torque locking feature in threaded fasteners. Test procedures are developed and tests are performed on three fastener materials, four anaerobic adhesives, and both unseated assembly conditions. Five to ten samples are tested for each combination. Tests for initial use, reuse without additional adhesive, and reuse with additional adhesive are performed for all samples. A 48-hour cure time was used for all initial use and reuse tests. Test data are presented as removal torque versus removal angle with the specification required prevailing torque range added for performance assessment. Percent specification pass rates for the all combinations of fastener material, adhesive, and assembly condition are tabulated and reveal use of anaerobic adhesive as a prevailing torque locking feature is viable. Although not every possible fastener material and anaerobic adhesive combination provides prevailing torque values within specification, any combination can be assessed using the test procedures presented. Reuse without additional anaerobic adhesive generally provides some prevailing torque, and in some cases within specification. Reuse with additional adhesive often provides comparable removal torque data as in initial use.

    2009-09-01

    This paper considers an international trade under Bertrand model with differentiated products and with unknown production costs. The home government imposes a specific import tariff per unit of imports from the foreign firm. We prove that this tariff is decreasing in the expected production costs of the foreign firm and increasing in the production costs of the home firm. Furthermore, it is increasing in the degree of product substitutability. We also show that an increase in the tariff results in both firms increasing their prices, an increase in both expected sales and expected profits for the home firm, and a decrease in both expected sales and expected profits for the foreign firm.

    Currently, the electric energy sector is preparing for the third round of the distributors tariff revisions. Since the regulatory environment is more consolidated in terms of required revenue, the agents are turning their attention to the necessary adjustment and correction of the tariff structure. In fact, ANEEL (regulatory agency) set topics for R and D projects considered strategic for the development of national energy sector, among them, the Tariff Structure Project. Recently, the regulatory agency also announced public hearings dealing with the costs allocation, price signals and tariffs for low-voltage consumers. In line with this debate, the thesis finds to analyze the methodology for calculating tariffs, systematizing knowledge dispersed in various references. For this, it discusses the major aspects of peak pricing theory, including American, British and French approaches, and researches the connection between the logic built into the costs allocation by hour and the criteria for electricity distribution system planning. Aiming to reflect the costs of each customer type, indicating a better utilization of the distribution system, are proposed improvements and innovation whose highlights are: shifting the idea that expansion costs should be only allocated in peak time of the system, setting the periods after calculating the costs, changing how to derive the reference charges by average aggregation of the costs and applying the methodology on altered load curves. Finally, this thesis seeks to prove that the current methodology, although designed by the time in which the electricity sector was aggregated, can be adapted according to the proposed improvements and innovations, and thus applied to the current environment in which electric energy businesses and tariffs are separated in generation, transmission, and distribution and retail areas.

    Full Text Available The average tariff reduction rate is 20% point higher in five developed countries analyzed in this study compared to five developing countries following the direction offered by the Chairman's Draft Text. Average tariff reduction rates are 31.6% for the five developing countries and 51.4% for the five developed countries. Korea's tariff reduction rate reaches to 36.1%, the highest reduction in developing countries, when Korea retains the developing country status. When Korea makes tariff reductions following the direction for developed countries, the average tariff reduction rate rises to 55.8%. Tariff reductions following the second Draft Text affect the tariff structure. Tariff escalation, dispersion and peaks can be mitigated by applying the tariff reduction methods proposed in the Second Draft Text. Tariff reductions give rise to the effects of reducing tariff escalation problem and the effects are stronger for the commodities with higher tariff rates and in developed countries. The average tariff rate for tariff peak commodities is reduced by 40% in developing countries and by 60% in developed countries. Tariff dispersion is also mitigated by reducing tariff rates. The difference of the average tariff rate between Korea and Australia is reduced to 38.5% from 59.8% by cutting tariff rates with the rules proposed in the second Draft Text. Korea needs to prepare the Country Schedule in advance to evaluate the potential outcome of the tariff cut following the Draft Text and to capture various voices from producers, consumers and other related institutions. For the preparation of the Country Schedule, Korea needs to decide minimum tariff cut items within a group of the commodity classified by tariff rates and this procedure requires discussion among producer and consumer groups.

    Ontario's deregulated energy sector promotes the production of clean or renewable energy by small power producers through distributed generation (DG). This presentation examined the policies that could be utilized to encourage DG investment and incorporated them into a mathematical model that was used to develop scenarios for examining the economic and environmental supply-side effects of policies on a distribution system over a ten year period. The policies that were analyzed included a combination of feed-in-tariffs; a carbon dioxide tax; and cap-and-trade schemes. The presentation discussed the results in terms of the Ontario electricity market and the standard offer program, implemented on a 32-bus radial distribution system. In addition, the presentation described a distribution system planning model that was suitable for examining the impact of regulatory policies on DG unit investments by small power producers (SPP) or the local distribution company (LDC). Three major policy cases representing a SPP-inclusive environment, a SPP-friendly environment incorporating feed-in tariffs, and a tightly regulated system with only the LDC participating were applied to the 32-bus radial distribution system using market and incentive rates currently in place. It was concluded that without additional incentives, DG units are close to being viable. Feed-in-tariffs, such as that in Ontario, are necessary to increase investments in combined heat and power and solar-photovoltaic units. refs., tabs., figs.

    ABT is a performance-based tariff for the supply of electricity by generators owned and controlled by the central government. It is also a new system of scheduling and dispatch, which requires both generators and beneficiaries to commit to day-ahead schedules. It is a system of rewards and penalties seeking to enforce day ahead pre-committed schedules, though variations are permitted if notified One and one half hours in advance. The order emphasizes prompt payment of dues. ABT (Availability Based Tariff) along with the Electricity Act of 2003 is perhaps the most significant and definitive step taken in the Indian power sector so far to bring more efficiency and focus to this vital infrastructure. The ABT mechanism is based on financial principles. ABT scheme is for unscheduled interchange of power. The paper reviews ABT issues, its components, clauses, mechanism, benefits and the impact of grid on different players like generation utilities, grid operator, consumers involved in power generation, transmission and distribution. While the proposed tariff structure has wide implications for each player, this deals exclusively with the technology challenges/opportunities thrown up by ABT.

  14. Urban Water Tariffs in Spain: What Needs to Be Done?

    Directory of Open Access Journals (Sweden)

    Miguel A. García-Rubio

    2015-03-01

    Full Text Available Recently, in the context of the Integrated Water Resources Management, demand policies are playing a more important role as opposed to traditional supply policies based on the construction of large hydraulic infrastructures. In this new context, water tariffs have become an important tool in achieving economic efficiency, environmental sustainability, and social equity. This paper reviews the situation of urban water tariffs in Spain, a country subject to high water stress. It analyzes the capacity of urban water tariffs to recover service costs and to promote efficiency, sustainability, affordability, and equity. Although it has made significant progress in recent years, the Spanish urban water tariff system still faces many challenges. Many of these challenges would be better addressed by a national independent regulatory body.

  15. Energy Prices, Tariffs, Taxes and Subsidies in Ukraine

    2007-04-01

    For many years, electricity, gas and district heating tariffs for residential consumers were very low in Ukraine; until recently, they were even lower than in neighbouring countries such as Russia. The increases in gas and electricity tariffs, implemented in 2006, are an important step toward sustainable pricing levels; however, electricity and natural gas (especially for households) are still priced below the long-run marginal cost. The problem seems even more serious in district heating and nuclear power. According to the Ministry of Construction, district heating tariffs, on average, cover about 80% of costs. Current electricity prices do not fully include the capital costs of power stations, which are particularly high for nuclear power. Although the tariff for nuclear electricity generation includes a small decommissioning charge, it has not been sufficient to accumulate necessary funds for nuclear plants decommissioning.

    In this paper, we study an international market model in which the home government imposes a tariff on the imported goods. The model has two stages. In the first stage, the home government chooses an import tariff to maximize a function that cares about the home firm's profit and the total revenue. Then, the firms engage in a Cournot or in a Stackelberg competition. We compare the results obtained in the three different ways of moving on the decision make of the firms.

    This paper analyzes tariff competition by investigating the strategic interactions among firms that are highly mobile across national boundaries. Although high transport costs yield a geographic dispersion of the industry, sufficiently low transport costs result in a core-periphery location where nobody bears tariff burdens. In any case, the world economy would be in a much better position under an international coordination scheme. An economy is only required to enforce a weak international ...

    This work tries to explain the tariff regulation experiences in the Italian electricity industry from the end of the second world war to now. These events, shown in the following tables, are divided into four phases: 1) the progressive standardization of electric power prices (1945-61); 2) the price control (1961-74); 3) the 'interferences' in the tariff system (1974-95); 4) the present deregulation (price-cap)

  20. EDF: The revision of the electrical supply tariff system

    International Nuclear Information System (INIS)

    Kaczmarek, A.M.

    1982-01-01

    The article deals with proposals by EDF for restructuring their tariffs for the supply of electricity. The objective is to take account of probable developments in demand, notably the steadily increasing gap between the summer and winter rates of consumption, and in generation, notably the large increase in the fraction of the total load that is met by nuclear stations. It is estimated that by 1990 generation will be 70% nuclear, 16% hydraulic, 9% by coal and 4% by oil, nuclear generation being by far the cheapest. The general philosophy of the new tariffs is: to retain the two-part (kW and kWh) structure; to simplify tariffs for small consumers; to apply to large consumers sophisticated tariffs that accurately reflect true costs of supply; to make maximum demand rather than supply voltage the determining factor; tariffs will be geographically uniform except for a few very large consumers favourably situated with respect to key points in the network; to adopt special means to spread peak loads. The new tariffs and some additional related measures for influencing the incidence of electricity consumption are described in some detail. (C.J.O.G.)

  1. Market and behavioral barriers to energy efficiency: A preliminary evaluation of the case for tariff financing in California

    Energy Technology Data Exchange (ETDEWEB)

    Fujita, K. Sydny

    2011-06-23

    the number of outdated appliances, in California rental housing. Appliances in rental housing are on average older than those in owner occupied housing. More importantly, a substantial proportion of very old appliances are in rental housing. Having established that a very old stock of appliances exists in California rental housing, I discuss tariff financing as a policy option to reduce the impact of the remaining market and behavioral barriers. In a tariff financing program, the utility pays the initial cost of an appliance, and is repaid through subsequent utility bills. By eliminating upfront costs, tying repayment to the gas or electric meter, requiring a detailed energy audit, and relying upon utility bill payment history rather than credit score in determining participant eligibility, tariff financing largely overcomes many barriers to energy efficiency. Using California as a case study, I evaluate the feasibility of implementing tariff financing. For water heaters in particular, this appears to be a cost-effective strategy. Tariff financing from utilities is particularly valuable because it improves the ability of low-income renters to lower their utility bills, without burdening landlords with unrecoverable capital costs. To implement tariff financing country-wide, regulations in many states defining private loan-making institutions or the allowable use of public benefit funds may need to be modified. Tariff financing is relatively new and in most locations is only available as a pilot program or has only recently exited pilot phase. This preliminary evaluation suggests that tariff financing is a valuable future addition to the toolkit of policymakers who aim to increase the diffusion of efficient appliances. While regulatory approval is necessary in states that wish to pursue tariff financing, at this point, the major barrier to further implementation appears to be the newness of the financing mechanism.

  2. Micro economic evaluations of transferal tariffs and income framework

    Wangensteen, Ivar; Groenli, Helle

    2000-01-01

    The report discusses conditions of transferral tariffs as micro economic measures in the income-regulating frameworks of today. The process from aim to implementation of the tariff measures is described and the conditions as the tariff goal, segmenting of the customers and their price sensitivity are discussed. The report deals specifically with construction grants and connection fees. Connection fees are proposed as measures in order to influence dimensioning, while construction grants may be suitable in certain conditions for influencing the localisation. These measures would have different effects on the network companies' incomes and costs also due to the accounting regulations. A selection of tariff measures is proposed that illuminate the problems of the network companies. ''How shall the present income frames be distributed among the customers in order to stimulate the reduction of the costs and an increase of the income framework.'' The tariff measures are illustrated by specific numeric examples and the influence on incomes and costs are discussed. Examples of tariff measures are: Do not use the connection fee but rather the construction grant or increase the firm power part, only use the energy part, effect part or the firm power part. Solely altering of the tariff parts may result in the following: 1) Altering the firm power part: An increase would give a more stable yearly profit. 2) Altering of the energy part: An increase would promote a reduced consumption and thereby negatively influence a possible increase in the income frames. An increase may on the other hand reduce the costs of loss and delay investments. 3) Altering of the effect part: An increase would promote reduced maximal effects, lower the costs of loss and delay investments. 4) Reducing the connection fee would increase the maximum construction grant that could be applied for. This would result in a larger part of the construction costs could be covered within the income frames and would

    Courchene, T.J.; Allan, J.R.

    2008-01-01

    Canada's ratification of the Kyoto Protocol will not adequately address the country's contribution to global climatic change. This paper proposed a 2-tier system consisting of internationally imposed carbon import tariffs combined with an equivalent domestic carbon tax. The approach was designed to engage global exporters and importers, while also involving governments and policy commitments related to emissions and cap-and-trade systems. Although a carbon tax on emissions is preferable to an opting-in approach, Canadian government has rejected carbon taxes due to the suspicion that Canadian companies will easily circumvent regulations. It is anticipated that many companies in carbon tax compliant countries will outsource production to non-compliant countries. The proposed approach required that carbon taxes will be applied to all domestically produced and consumed products, while tariffs will be levied against products from exporting firms. Outsourcing to take advantage of lax environmental policies in pollution havens will be subject to a carbon footprint tariff. The tariff will also serve to reduce the carbon content of exports. Proceeds of the tax can be used in a variety of ways to reduce greenhouse gas (GHG) emissions. It was concluded that Canada will need to supplement domestic carbon taxes with a proposed carbon import tariff. 1 fig

    Full Text Available Tariff rates are crucial instrument of trade policy. This paper covers several important issues related to the reforms of this area. First part of the paper explains the key features of tariffs as protection instrument: different policy takers and opposite economic interests; benefits and adverse effects; alternative measures of protection; dependence of tariff policy on the development priorities and the welfare effects, etc. This document explains main World Trade Organization requirements concerning protection policy such as primary role of tariffs, restricted set of non-tariff instruments, limited scope of safeguard measures, comparison on the legal development in the field until now, and an indication of further legislation changes necessary in the period of adjustment. It also gives main elements of the customs-reform strategy: choice and concentration of goals and priorities; criteria for preparation of the alternative scenarios; solving convergence problems; defining conditionality for alternative solutions and interdependence of relevant externalities. The goal of the paper is to give recommendation for trade policy reform in our country necessarily to become member of World Trade Organization.

  5. Grid-connected photovoltaic systems for Malaysian residential sector: Effects of component costs, feed-in tariffs, and carbon taxes

    Blessed with abundant solar radiation, Malaysia has a huge potential for grid-connected PV (photovoltaic) installations, particularly for its fast-growing residential sector. Nevertheless, Malaysia's PV installation capacity is relatively small compared with the global PV capacity. Significantly, the pricing mechanisms for grid-connected PV projects need to be appropriately assessed to build up the public's confidence to invest in PV projects. In this paper, we analyze the effects of component costs, FiTs (feed-in tariffs), and carbon taxes on grid-connected PV systems in Malaysian residential sector using the HOMER (Hybrid Optimization of Multiple Energy Resources) software. Results demonstrate that the implementation of grid-connected PV systems is highly feasible with PV array costs of $ 1120/kW or lower. For higher PV array costs up to $ 2320/kW, introducing an FiT rate three times higher ($ 0.30/kWh) than the grid tariff for a 100 kW grid sale capacity will, NPC-wise, prioritize grid-connected PV systems over the utility grid. By implementing the FiT ($ 0.50/kWh) and the carbon tax ($ 36/metric ton) schemes simultaneously, grid-connected PV systems will remain as the optimal systems even for costly PV arrays (up to $ 4000/kW). The findings are of paramount importance as far as PV pricing variability is concerned. - Highlights: • Grid-connected PV for Malaysian residential sector has been analyzed using HOMER. • Component costs, feed-in tariffs, and carbon taxes affect optimal system types. • Grid-connected PV projects are feasible for low PV array costs ($ 1120/kW or lower). • For higher PV array and inverter costs, feed-in tariffs should be implemented. • Combining feed-in tariffs with carbon taxes are effective for further lowering NPCs.

    Mobile telecommunication operators routinely charge subscribers lower prices for calls on their own network than for calls to other networks (on-net discounts). Studies on tariff-mediated network effects suggest this is due to large operators using on-net discounts to damage smaller rivals....... Alternatively, research on strategic discounting suggests that small operators use on-net discounts to advertise with low on-net prices. We test the relative strength of these effects using data on tariff setting in German mobile telecommunications between 2001 and 2009. We find that large operators are more...

    Foundations of price-setting and order of accounting arrangement for NPP electric power are considered. NPP tariffs are established proceeding from standard costs of power generation. The standards are differentiated as to NPP groups, depending on technical, regional and natural geographic factors, taking into account the facility type, unit capacity and the number of similar NPP units. The conclusion is made that under conditions of NPP economic independence expansion and creation of prerequisites for going over to self-financing principles and also due to the qualitatively new stage of nuclear power generation development the level of efficiency, forseen by the tariffs, should be increased

  13. Drug price regulation under consumer moral hazard. Two-part tariffs, uniform price or third-degree price discrimination?

    Science.gov (United States)

    Felder, Stefan

    2004-12-01

    Drug price differences across national markets as they exist in the EU are often justified by the concept of Ramsey prices: with fixed costs for R&D, the optimal mark-ups on marginal costs are inversely related to the price elasticity in the individual markets. This well-known result prevails if consumer moral hazard is taken into account. Contrary to the situation without moral hazard, the uniform price does not necessarily dominate discriminatory pricing in welfare terms. The two-part tariff is a better alternative as it allows governments to address moral hazard. A uniform price combined with lump-payments reflecting differences in the willingness to pay and the moral hazard in member states appears to be an attractive option for a common EU drug market.

  20. Network ownership and optimal tariffs for natural gas transport

    International Nuclear Information System (INIS)

    Hagen, Kaare P.; Kind, Hans Jarle; Sannarnes, Jan Gaute

    2004-11-01

    This paper addresses the issue of national optimal tariffs for transportation of natural gas in a setting where national gas production in its entirety is exported to end-user markets abroad. In a situation where the transportation network is owned altogether by a vertically integrated national gas producer, it is shown that the optimal tariff depends on the ownership structure in the integrated transportation company as well as in the non-facility based gas company. There are two reasons why it is possibly optimal with a mark-up on marginal transportation costs. First, there is a premium on public revenue if domestic taxation is distorting. Second, with incomplete national taxation of rents from the gas sector, the transportation tariffs can serve as a second best way of appropriating rents accruing to foreigners. In a situation where the network is run as a separate entity subject to a rate of return regulation, it will be optimal to discriminate the tariffs between shippers for the usual Ramseyean reasons.

    2018-04-01

    Genetically modified organisms have been at the centre of a major public controversy, involving different interests and actors. While much attention has been devoted to consumer views on genetically modified food, there have been few attempts to understand the perceptions of genetically modified technology among farmers. By investigating perceptions of genetically modified organisms among Brazilian farmers, we intend to contribute towards filling this gap and thereby add the views of this stakeholder group to the genetically modified debate. A comparative analysis of our data and data from other studies indicate there is a complex variety of views on genetically modified organisms among farmers. Despite this diversity, we found variations in such views occur within limited parameters, concerned principally with expectations or concrete experiences regarding the advantages of genetically modified crops, perceptions of risks associated with them, and ethical questions they raise. We then propose a classification of prevailing profiles to represent the spectrum of perceptions of genetically modified organisms among farmers.

  9. Do feed-in tariffs drive PV cost or viceversa?

    International Nuclear Information System (INIS)

    2014-01-01

    Highlights: • The distribution of PV installations on the territory is not a function of the solar radiation. • Cost of PV plants were adapted to the FIT framework. • The FIT for PV in Italy was considered an incentive to financial investment. • The FIT for PV in Italy did not stimulate the development of national PV industry. - Abstract: A survey of the PV market in Italy was done studying a number of installations of different sizes whose economic data were known and assessed. The Italian market has experienced a boom in the PV market after the first mechanism of feed-in tariffs was promoted in 2005. The variations of the tariff structure in the following years have caused significant changes in the market structure in terms of average size and technical characteristics of installed plants. However, an Italian PV industry was not stimulated by the incentives and only companies involved in installation and maintenance were created. At the same time, the cost of the PV plants components, design and commissioning have followed quite a particular trend, which is more determined by the tariffs than by the market development and structure. It is quite clear that the costs of PV plants component are not driven by the amount of installations but by the tariffs, with a trend that follows the decreases in the incentives and not the global installed power. It is therefore very important to study the right tariff mechanisms and benefits to avoid financial disturbances on the market and to promote a real competitive market instead of a simple financial operation under a fake façade of green economy

    Full Text Available This paper aims to investigate a method of peak load shaving through the utilization of solar PV and battery energy storage whilst creating a cost effective Energy Management System (EMS. This is achieved by utilizing a rule-sets to manage and optimize a scheduling system with a forecasting algorithm. As Time of Use (ToU tariffs change throughout the day, a cost benefit can be achieved when a smart energy storage system is appropriately employed. The EMS operation is tested on an experimental microgrid with commercial load considering payback period calculation.

    While more than 70 utilities in the U.S. have offered voluntary RTP tariffs on either a pilot or permanent basis, most have operated in relative obscurity. To bring this broad base of experience to bear on policymakers current efforts to stimulate price responsive demand, we conducted a survey of 43 voluntary RTP tariffs offered in 2003. The survey involved telephone interviews with RTP program managers and other utility staff, as well as a review of regulatory documents, tariff sheets, program evaluations, and other publicly available sources. Based on this review of RTP program experience, we identify key trends related to: utilities motivations for implementing RTP, evolution of RTP tariff design, program participation, participant price response, and program outlook. We draw from these findings to discuss implications for policymakers that are currently considering voluntary RTP as a strategy for developing price responsive demand.

    Generally speaking, the creation of tariff systems for energy activities carried out as regulated or public service obligation is becoming professionally challenging. The Croatian Energy Regulatory Agency (CERA) created the methodology of the tariff system for thermal energy activities and passed this tariff system (without tariff element amounts) in May 2006. The background of the tariff system for thermal energy activities (heat generation, heat distribution and heat supply) including a legislative framework relevant for passing the tariff system, terminology, matrix of the tariff models, tariff elements and amounts of tariff entries are analyzed in this paper. Special attention is paid to the economic characteristics of the tariff system, such as the capital asset pricing model (CAPM), which is chosen among several models of the weighted average of cost of capital (WACC). Using the WACC, the regulatory authorities ensure returns to be equal to the opportunity cost of capital. Furthermore, main formulae and procedures for submitting the proposal for changing the amounts of tariff elements are analyzed as well. (author)

    2016-01-01

    Schizophrenia's (SZ's) heritability and familial transmission have been known for several decades; however, despite the clear evidence for a genetic component, it has been very difficult to pinpoint specific causative genes. Even so genetic studies have taught us a lot, even in the pregenomic era, about the molecular underpinnings and disease-relevant pathways. Recurring themes emerged revealing the involvement of neurodevelopmental processes, glutamate regulation, and immune system differential activation in SZ etiology. The recent emergence of epigenetic studies aimed at shedding light on the biological mechanisms underlying SZ has provided another layer of information in the investigation of gene and environment interactions. However, this epigenetic insight also brings forth another layer of complexity to the (epi)genomic landscape such as interactions between genetic variants, epigenetic marks-including cross-talk between DNA methylation and histone modification processes-, gene expression regulation, and environmental influences. In this review, we seek to synthesize perspectives, including limitations and obstacles yet to overcome, from genetic and epigenetic literature on SZ through a qualitative review of risk factors and prevailing hypotheses. Encouraged by the findings of both genetic and epigenetic studies to date, as well as the continued development of new technologies to collect and interpret large-scale studies, we are left with a positive outlook for the future of elucidating the molecular genetic mechanisms underlying SZ and other complex neuropsychiatric disorders.

    2017-09-01

    In language acquisition research, the prevailing position is that listeners exploit statistical cues, in particular transitional probabilities between syllables, to discover words of a language. However, other cues are also involved in word discovery. Assessing the weight learners give to these different cues leads to a better understanding of the processes underlying speech segmentation. The present study evaluated whether adult learners preferentially used known units or statistical cues for segmenting continuous speech. Before the exposure phase, participants were familiarized with part-words of a three-word artificial language. This design allowed the dissociation of the influence of statistical cues and familiar units, with statistical cues favoring word segmentation and familiar units favoring (nonoptimal) part-word segmentation. In Experiment 1, performance in a two-alternative forced choice (2AFC) task between words and part-words revealed part-word segmentation (even though part-words were less cohesive in terms of transitional probabilities and less frequent than words). By contrast, an unfamiliarized group exhibited word segmentation, as usually observed in standard conditions. Experiment 2 used a syllable-detection task to remove the likely contamination of performance by memory and strategy effects in the 2AFC task. Overall, the results suggest that familiar units overrode statistical cues, ultimately questioning the need for computation mechanisms of transitional probabilities (TPs) in natural language speech segmentation.

  20. Dynamic Power Tariff for Congestion Management in Distribution Networks

    DEFF Research Database (Denmark)

    Huang, Shaojun; Wu, Qiuwei; Shahidehpour, Mohammad

    2018-01-01

    This paper proposes dynamic power tariff (DPT), a new concept for congestion management in distribution networks with high penetration of electric vehicles (EVs), and heat pumps (HPs). The DPT concept is proposed to overcome a drawback of the dynamic tariff (DT) method, i.e., DPT can replace...... the price sensitivity parameter in the DT method, which is relatively unrealistic in practice. Based on the control theory, a control model with two control loops, i.e., the power flow control and voltage control, is established to analyze the congestion management process by the DPT method. Furthermore......, an iterative method based on distributed optimization is proposed to determine the DPT rates, which enables active participation of aggregators in the congestion management. The case studies demonstrate the efficacy of the DPT method for congestion management in distribution networks, and show its ability...

  1. No way around green tariffs; Oekotarife sind nicht mehr wegzudenken

    Briese, Dirk [trend:research GmbH, Stuttgart (Germany)

    2011-05-15

    Just like green electricity, meanwhile a classic, so too now does newcomer ''green gas'' offer energy suppliers with an appropriate marketing mix far-reaching opportunities for improving their corporate image, securing customer loyalty and increasing turnover. However the only beneficiaries of this trend to date have been green-only suppliers which specialise in this market. Although most traditional suppliers have now added green tariffs to their product portfolio, this has given them little commercial success, since eco-minded consumers often consider green-only suppliers to be more credible. A recent study shows that the market volume of green electricity and green gas tariffs will grow markedly over the next five years. Energy suppliers should therefore turn their attention to the question of how they can best exploit this potential.

    (1) We estimate CO 2 implicitly exported via commodities relative to a region's total emissions: We find −15% for the industrialized, 12% for the developing region, and 24% for China. (2) We analyze a Contraction and Convergence climate regime in a CGE model including international capital mobility and technology diffusion: When China does not participate in the regime and instead a carbon tariff is imposed on its exports, it will likely be worse off than when participating. This result does not hold for the developing region in general. Meanwhile, the effect on emissions appears small. - Highlights: ► Carbon intensities and contents of trade by commodity and region using GTAP 7. ► Net carbon exports: industrialized region −15%, developing region 12%, China 24%. ► CGE analysis of carbon tariffs based on our carbon intensities. ► The tariffs make China worse off than climate policy and are ambiguous for the developing region. ► They have a small impact on reducing global emissions.

    Full Text Available Soybean is one of the major food commodities after rice and maize which have the advantage of protein-rich, therefore its usefulness as a food of vegetable protein source are various. National soybean consumption in 2011 amounted to 2.95 million tons, while domestik production had reached 851 thousand tons, there is a deficiency that must be imported around 2.1 million tons or about 71 percent of the total national consumption. Government support policies (seed, fertilizer and mechanization subsidy have increased farmers’ profit. However, protection policy such as import tariff of around 15.8 percent, 27.7 percent or 41.4 percent should be considered, in order farmer to achieve profits around 25 percent, 30 percent or 35 percent of total revenue, respectively. Import tariff above 27 percent could not be applied because bound rate of import soybean is 27 percent. Currently, the profit of soybean farming is around 16.5 percent of total revenue. The main purpose of this paper are as follows: (a to analyze the profitability of soybean farming system; (b to analyze the impact of government policies (import tariff on the economy in general, and (d to formulate policy recommendations for development of soybean industry and farmers’ income

    Full Text Available Purpose: Reducing carbon emission has been the core problem of controlling global warming and climate deterioration recently. This paper focuses on the optimal carbon taxation policy levied by countries and the impact on firms’ optimal production decisions. Design/methodology/approach: This paper uses a two-stage game theory model to analyze the impact of carbon tariff and tax. Numerical simulation is used to supplement the theoretical analysis. Findings: Results derived from the paper indicate that the demand in an unstable market is significantly affected by environmental damage level. Carbon tariff is a policy-oriented tax while the carbon tax is a market-oriented one. Comprehensive carbon taxation policy benefit developed countries and basic policy is more suitable for developing countries. Research limitations/implications: In this research, we do not consider random demand and asymmetric information, which may not well suited the reality. Originality/value: This work provides a different perspective in analyzing the impact of carbon tax and tariff. It is the first study to consider two consuming market and the strategic game between two countries. Different international status of countries considered in the paper is also a unique point.

    Point-of-connection (POC) scheme of transmission pricing in decentralized markets charges the participants a single rate per MW depending on their point-of-connection. Use of grossly aggregated postage stamp rates as POC charges fails to provide appropriate price signals. The POC tariff based on distribution of network sunk costs by employing conventional tracing assures recovery of sunk costs based on extent of use of network by participants. However, the POC tariff by this method does not accommodate economically efficient price signals which correspond to marginal costs. On the other hand, the POC tariff, if made proportional to marginal costs alone, fails to account for sunk costs and extent of use of network. This paper overcomes these lacunae by combining the above stated desired objectives under the recently proposed optimal tracing framework. Since real power tracing problem is amenable to multiple solutions, it is formulated as linearly constrained optimization problem. By employing this methodology, consideration of extent of network use and sunk cost recovery are guaranteed, while objective function is designed such that the spatial pattern of price signals closely follows the pattern of scaled locational marginal prices. The methodology is tested on IEEE 30 bus system, wherein average power flow pattern is established by running various simulation states on congested and un-congested network conditions. (author)

    2014-12-01

    The paper addresses an important element of the European energy sector: the evaluation of district heating (DH) system operations from the standpoint of increasing energy efficiency and increasing the use of renewable energy resources. This has been done by developing a new methodology for the evaluation of the heat tariff. The paper presents an algorithm of this methodology, which includes not only a data base and calculation equation systems, but also an integrated multi-criteria analysis module using MADM/MCDM (Multi-Attribute Decision Making / Multi-Criteria Decision Making) based on TOPSIS (Technique for Order Performance by Similarity to Ideal Solution). The results of the multi-criteria analysis are used to set the tariff benchmarks. The evaluation methodology has been tested for Latvian heat tariffs, and the obtained results show that only half of heating companies reach a benchmark value equal to 0.5 for the efficiency closeness to the ideal solution indicator. This means that the proposed evaluation methodology would not only allow companies to determine how they perform with regard to the proposed benchmark, but also to identify their need to restructure so that they may reach the level of a low-carbon business.

    Full Text Available This study uses vector error correction model to examine the effects of oilseeds, crude oil and vegetable oil tariffs on vegetable oil consumer price. Monthly data sets for the years 2004-2013 and VAR and VECM models were applied for this study. Research findings indicates only a long term equilibrium relation between the study variables .The effect of vegetable oil tariffs on consumer and producer price index are 0.4 and 0.07, respectively. Furthermore, one percent increase in the oil seeds and crude oil tariff, will increase consumer prices by 2.35, 0.19percent. The huge gap between the impacts of the two tariffs –e.g. oilseeds and crude oil tariffs- on consumer price shows that oil industries work with low efficiency. This practically doubles the impact of tariff on consumers. Accordingly, structural reform in the oil industry can develop oil production and prevent additional burden upon the consumer price.

    2011-12-01

    Full Text Available This paper consists of information regarding current situation of international trade relations, in particular those pertaining to EU, concerning to preferential trade agreements, the trend towards globalization and custom policies. The importance of this document is given by the identification of strategy trends in respect to EU tariff policy in the context of changes at commercial exchange level, as a consequence of international trade globalization's trend. The tariff policy, as a component of the trade one, represents a factor which influences companies behavior and, consequently the structure of import-export interstates relations. Specialty literature has lately identified a less natural phenomenon: starting with adoption by WTO states members of some measures and principles that emphasize the trade globalization tendency, a significant number of preferential agreements were settled in the meanwhile, many of them being bilateral, fact at least at first view is opposite to globalization phenomenon. The causes of this phenomenon have not been yet completely identified by economic analysts, so that these preferential trade agreements can be translated as a an impediment in the way of globalization and, on the contrary an intermediate phase and an accelerator of global extension trade exchange phenomenon. The present work ideas are based on analysis by bibliographic guide that link to historical GATT/WTO and principles which sustain its operation and to dynamic of international trade. Also, there have been studied data related to strategies of trade policy adopted by EU. The results consist of information about tariff policy elements adopted or forecasted by EU in general strategic context of participation to international trade. Particularly, it is emphasized the new competencies that must be achieved by custom personnel because of changes in trade exchanges. The main idea is represented by the necessity of custom authorities responsibility

    In all countries where the gas industry has reached a significant level of development, the public authorities subject companies to restrictions and control of various types. The intervention of the State influences significantly the gas sector. In this respect the relations with concession system should be taken into account as well as the relations between transmission company and distribution companies. A distinction is to be made in sales at two market segments, commercial and residential and industrial. Basic criteria for a tariff system are based on balancing revenue and costs, and constant control of costs. Standard cost components are: raw materials, staff, real estate management, operation costs and general expenses

    2013-10-01

    In this paper, we study the effects of environmental and trade policies in an international mixed duopoly serving two markets, in which the public firm maximizes the sum of consumer surplus and its profit. We also analyse the effects of privatization. The model has two stages. In the first stage, governments choose environmental taxes and import tariffs, simultaneously. Then, the firms engage in a Cournot competition, choosing output levels for the domestic market and to export. We compare the results obtained in the three different ways of moving on the decision make of the firms.

    Feed-in tariffs (FITs) are the most prevalent policy used globally to reduce development risks, cut financing costs, and grow the renewable energy industry. However, concerns over escalating costs in jurisdictions with FIT policies have led to increased attention on cost control. Using case studies and market-focused analysis, this report from the National Renewable Energy Laboratory (NREL) examines strengths and weaknesses of three cost-containment tools: (1) caps, (2) payment level adjustment mechanisms, and (3) auction-based designs. The report provides useful insights on containing costs for policymakers and regulators in the United States and other areas where FIT policies are in development.

    With the advent of grid connected solar panels in India, the requirement of a separate mechanism for metering and billing is foreseen. The policy framework for addressing this need is under process in various states of India. In the smart grid pilot project at Puducherry, India, a simple net metering mechanism has been incorporated to evaluate and understand the performance of green energy generation through solar panels. The present paper draws a comparison between net metering and gross metering mechanisms, through the analysis of net meter data collected for three different types of consumers from the pilot project at Puducherry. Different scenarios have been evaluated to infer the impacts of specialized billing mechanisms as well as the payback periods on investment made for solar energy systems and the savings that is reflected in the monthly bills. Feed in tariff renders full credit to the renewable energy customers on their electricity bills for the amount of green power, which is sent back to the main grid. This simple mechanism of a credit system would prove to be the most important energy policy for a nation to encourage sustainable energy generation. Due to wide variations in tariffs, requirements and efficiency of utilities across the different states in India, a policy which can accommodate mechanisms of community net metering and aggregate net metering had become a necessity. The paper signifies the crucial and immediate necessity for a feasible and acceptable energy policy so as to realize the benefits of power from the sun. - Highlights: • Study of net metering data in smart grid pilot project in India. • Scenario analysis for savings in electricity under different cases. • Comparison of net metering and gross metering mechanisms. • Net metering is found to be more beneficial than gross metering. • Suggestions for alternative net metering techniques for developing countries.

    Aim The investigators aimed to assess the willingness of patients to utilize and pay for a proposed short message service- (SMS) based appointment scheduling service. Telecommunication applications have been introduced to improve the delivery of healthcare services in developed countries; however, public-funded healthcare systems in developing countries like Nigeria are mostly unfamiliar with the use of such technologies for improving healthcare access. We proposed a SMS-based (text message) appointment scheduling system to consenting subjects at an outpatients' clinic and explored their willingness to utilize and pay for the service. Using semi-structured interview schedules, we collected information on: estimated arrival time, most important worry when seeking for healthcare services at public hospitals in the study setting, ownership of a mobile phone, willingness to utilize a SMS-based appointment for clinic visits and willingness to pay for the service. In addition, respondents were asked to suggest a tariff for the proposed system. Findings A total of 500 consecutively recruited patients aged 16-86 (42.1±15.4) years participated; 54% (n=270) were females. Waiting time ranged from 1-7.5 h (3.9±1.1). Two overlapping themes emerged as most important worries: crowded waiting rooms and long waiting time. Ownership of mobile phones was reported by 96.4% (n=482) of subjects. Nearly all favoured the proposed appointment scheduling system (n=486, 97.2%). Majority of patients who favoured the system were willing to pay for the service (n=484, 99.6%). Suggested tariff ranged from 0.03 to 20.83 (1.53±2.11) US dollars; 89.8% (n=349) of the subjects suggested tariffs that were greater than the prevailing retail cost of the proposed service. In sum, our findings indicate that patients in this study were willing to utilize and pay for a proposed SMS-based appointment scheduling system. The findings have implications for policies aimed at improving healthcare access and

    2017-01-01

    Full Text Available This study analyses the effects of tariff escalation on Ghanaian cocoa exports in four importing markets: USA, EU, Japan and Malaysia. The study estimates nominal and effective protection coefficients in these markets based on ad-valorem equivalent of applied and bound specific tariffs. Results revealed that, effective protection exists in the Japanese and Malaysian cocoa industries at different stages of processing on both bound and applied tariffs. In contrast, the USA and the EU do not effectively protect their cocoa industries, thus, no tariff escalation on applied tariffs against cocoa imports from Ghana. This study concludes that from a static effect, higher tariffs do have a negative consequence on Ghanaian cocoa exports in these importing countries. From a dynamic perspective however, the relationship between tariff structures in these importing countries and Ghanaian cocoa exports is somewhat ambiguous and each situation has to be viewed on their own merit. A complete elimination of tariffs as a form of trade barrier on Ghanaian cocoa exports does not necessarily imply that Ghana could easily increase its exports of value added cocoa.

    2016-08-01

    Background The amount of direct hand-tool-tissue interaction and feedback in minimally invasive surgery varies from being attenuated in laparoscopy to being completely absent in robotic minimally invasive surgery. The role of haptic feedback during surgical skill acquisition and its emphasis in training have been a constant source of controversy. This review discusses the major developments in haptic simulation as they relate to surgical performance and the current research questions that remain unanswered. Search Strategy An in-depth review of the literature was performed using PubMed. Results A total of 198 abstracts were returned based on our search criteria. Three major areas of research were identified, including advancements in 1 of the 4 components of haptic systems, evaluating the effectiveness of haptic integration in simulators, and improvements to haptic feedback in robotic surgery. Conclusions Force feedback is the best method for tissue identification in minimally invasive surgery and haptic feedback provides the greatest benefit to surgical novices in the early stages of their training. New technology has improved our ability to capture, playback and enhance to utility of haptic cues in simulated surgery. Future research should focus on deciphering how haptic training in surgical education can increase performance, safety, and improve training efficiency. © The Author(s) 2016.

    Airway management during anaesthesia has potential difficulties and risks. We aimed to investigate the utility of routine airway assessment for predicting difficult tracheal intubation, review the prevailing practice of videolaryngoscope use amongst anaesthetists in a teaching hospital and determine the incidence of intraoperative and postoperative airway-related complications. A prospective observational study of 1,654 patients undergoing general anaesthesia with endotracheal intubation over a seven-month period was performed. Data regarding airway and anaesthetic management was collected and analysed. Videolaryngoscopes were used as the first-choice equipment in 60.5% of the cohort. The incidence of difficult intubation was 2.1%, of which 45.7% of cases were unanticipated. The sensitivity of airway assessment was 54.3%, with a positive predictive value of 8.1%. When difficult intubation was anticipated, more videolaryngoscopes were used as the first equipment of choice compared to the Macintosh laryngoscope (p < 0.001). In the Macintosh group, more patients required a change of airway equipment (p = 0.015), but the number of intubation attempts was similar (p = 0.293). The incidence of intraoperative (p = 0.920) and postoperative complications (p = 0.380) were similar in both groups. Using the current predictors of difficult intubation, half of the difficult airways we encountered were unanticipated. Videolaryngoscopes were preferred when difficulty was anticipated and were also used in routine tracheal intubation. Copyright: © Singapore Medical Association.

  16. On-grid electricity tariffs in China: Development, reform and prospects

    2011-01-01

    With the introduction of market-oriented measures in China's power sector in the mid-1980s, electricity sale prices to the grid companies-on-grid electricity tariffs-became the focus of the energy industry, thus affecting all related stakeholders, including fuel suppliers, power generators and end-use consumers. A number of changes have gradually been undertaken in terms of electricity tariff settings and their implementation to address specific requirements of the expansion of the power industry at each stage of its development. On-grid electricity tariffs had been used as a key lever to attract investment in power generation at an early stage of reform and then to encourage competition in the power industry. In response to the rising concerns about environmental protection and the promotion of clean energy utilisation, tariffs have progressively been developed for renewable electricity generation, which has contributed to massive expansion of the renewable power industry in China. This paper reviews key milestones of the development of on-grid electricity tariffs in China, examines the tariff-setting mechanisms of coal-fired power plants and renewable power generation, analyses the factors associated with the adjustments of the tariff levels and discusses the options for further reform and more effective electricity pricing. - Research highlights: → Pragmatic approaches have been taken to adjust on-grid electricity tariffs. → Current tariff policies of coal-power led to suboptimal resource utilisation. → Further market-oriented reforms are needed. → Feed-in tariffs have gradually been established for renewable electricity.

  17. Tax-tariff reform with costs of tax administration

    DEFF Research Database (Denmark)

    Munk, Knud Jørgen

    As is broadly recognized, the straightforward application of the Diamond-Mirrlees (1971) production efficiency theorem implies that when lump-sum taxation is not available, then it is optimal for the government in a small open economy to rely on taxes on the net demand of ouseholds rather than...... on border taxes to finance its resource requirements. However, the theorem does not hold when taxation is associated with administrative costs. The present paper explores the implications of taking into account the costs of tax administration for optimal taxation and for desirable directions of tax......-tariff reform in countries at different levels of economic development. The paper clarifies the reasons for, and lends support to, the criticism by Stiglitz (2003) of the IMF and the World Bank's recommendation to developing countries to adopt VAT to replace border taxes....

    Since 2011, Malaysia's overarching policy framework for clean energy development, the New Energy Policy, has led to significant deployment of renewable energy and energy efficiency. Building on the New Energy Policy, Malaysia mandated adoption of a renewable energy feed-in tariff (FiT) mechanism under the 2011 Renewable Energy Act. In 2013, Malaysia's Sustainable Energy Development Authority partnered with the Clean Energy Solutions Center and the Clean Energy Regulators Initiative (CERI), via the Ask an Expert service, to implement FiT policies and expand renewable energy development. Through collaboration between the government of Malaysia and the Clean Energy Solutions Center, concrete policy action was supported and implemented, building a strong framework to expand and catalyze clean energy development.

    This report examines some of the key drivers and considerations policymakers and decision makers face when deciding if and how to regulate electricity tariffs for micro-grids. Presenting a range of tariff options, from mandating some variety of national (uniform) tariff to allowing micro-grid developers and operators to set fully cost-reflective tariffs, it examines various benefits and drawbacks of each. In addition, the report and explores various types of cross-subsidies and other transitional forms of regulation that may offer a regulatory middle ground that can help balance the often competing goals of providing price control on electricity service in the name of social good while still providing a means for investors to ensure high enough returns on their investment to attract the necessary capital financing to the market. Using the REopt tool developed by the U.S. Department of Energy's National Renewable Energy Laboratory to inform their study, the authors modeled a few representative micro-grid systems and the resultant levelized cost of electricity, lending context and scale to the consideration of these tariff questions. This simple analysis provides an estimate of the gap between current tariff regimes and the tariffs that would be necessary for developers to recover costs and attract investment, offering further insight into the potential scale of subsidies or other grants that may be required to enable micro-grid development under current regulatory structures.

    Layer, Patrick; Feurer, Sven; Jochem, Patrick

    2017-01-01

    Dynamic tariffs have the potential to contribute to a successful shift from conventional to renewable energies, but tapping this potential in Europe ultimately depends on residential consumers selecting them. This study proposes and finds that consumer reactions to dynamic tariffs depend on the level of perceived price complexity that represents the cognitive effort consumers must engage in to compute the overall bill amount. An online experiment conducted with a representative sample of 664 German residential energy consumers examines how salient characteristics of dynamic tariffs contribute to perceived price complexity. Subsequently, a structural equation model (SEM) reveals that the depth of information processing is central to understand how price complexity relates to consumers’ behavioral intentions. The results suggest that it will be challenging to convince European consumers to select complex dynamic tariffs under the current legal framework. Policymakers will need to find ways to make these tariffs more attractive. - Highlights: • Little is known about the processes by which consumers evaluate dynamic tariffs. • In this evaluation process perceived price complexity plays a central role. • Tariff type, price endings, and discount presentation format drive price complexity. • Perceived price complexity decreases the depth of information processing. • A decreased depth of information processing ultimately leads to lower behavioral intentions.

    Full Text Available This article revisits Michel Chevalier’s work and discussions of tariffs. Chevalier shifted from Saint-Simonism to economic liberalism during his life in the 19th century. His influence was soon perceived in the political world and economic debates, mainly because of his discussion of tariffs as instruments of efficient transport policies. This work discusses Chevalier’s thoughts on tariffs by revisiting his masterpiece, Le Cours d’Économie Politique. Data Envelopment Analysis (DEA was conducted to test Chevalier’s hypothesis on the inefficiency of French tariffs. This work showed that Chevalier’s claims on French tariffs are not validated by DEA.

    2012-01-01

    Electricity is the guarantee of normal life, and the electricity price is widely concerned. As a developing country in the transition stage, abundant policy implications are included in the electricity price in China, thus, whether to adjust the resident electricity price is a dilemma for the government. However, the current single tariff system cannot cope with the complex social and environmental problems. A new price mechanism is indeed needed. This paper tries to design an increasing block tariffs system with the consideration of residential income and electricity consumption. The result indicates that the increasing block tariffs system with four-tier structure is more reasonable for China. Although the increasing block tariffs will result in the increase of electricity price, it is still acceptable and affordable. The increasing block tariffs will greatly improve the equity and efficiency, and promote the electricity saving and emissions reduction. Moreover, the power companies will increase tariffs revenue, which would use to the transmission networks investment in poor area. In order to the offset the limitations of the increasing block tariffs, the government should adopt some complementary measures. - Highlights: ► We design an increasing block tariffs for residential electricity consumption with four-tier structure. ► Both the equity and efficiency will be greatly improved. ► Electricity demand and CO 2 emissions will reduce by 26.68 billion kWh and 14.11 million tons. ► Some measures should be taken as the complement to make the increasing block tariffs mechanism more efficient.

  8. Evaluating Welfare Effects of Rice Import Quota in Japan: Based on Measuring Non-Tariff Barriers of SBS Rice Imports

    2016-08-01

    Full Text Available The principal objective of this study is to analyze welfare effects of Japan’s rice import quota focusing on the simultaneous buy and sell (SBS of the rice importation minimum access (MA policy. Based on the utility function specified in this study, the constructed model is adopted to measure consumption patterns through estimating elasticity of substitution between imported rice and Japan’s domestic rice, and consumers’ preference parameters for different kinds of rice. The results showed that Japanese households prefer domestic rice to the imported rice. Besides, three scenarios of adjusting rice quota volumes were carried out to examine the changes in consumer prices of imported rice and Japanese consumers’ welfares. The results revealed that tariff equivalents of the SBS import quota almost doubled the scale of the mark-up, and the intervention by the Ministry of Agriculture of Japan did cause non-tariff barriers to trade (NTBs. Finally, if the SBS rice quota quantity was fixed at or larger than 180 thousand tons every fiscal year, the consumer prices of imported rice in Japan’s market would decrease to be less than the prices of Japan’s domestic rice, and therefore the imported rice would have more price advantages in this scenario.

  9. The analysis of Taiwan's residential electricity demand under the electricity tariff policy

    Science.gov (United States)

    Chen, Po-Jui

    In October 2013, the Taiwan Power Company (Taipower), the monopolized state utility service in Taiwan, implemented an electricity tariff adjustment policy to reduce residential electricity demand. Using bi-monthly billing data from 6,932 electricity consumers, this study examine how consumers respond to an increase in electricity prices. This study employs an empirical approach that takes advantage of quasi-random variation over a period of time when household bills were affected by a change in electricity price. The study found that this price increase caused a 1.78% decline in residential electricity consumption, implying a price elasticity of -0.19 for summer-season months and -0.15 for non-summer-season months. The demand for electricity is therefore relatively inelastic, likely because it is hard for people to change their electricity consumption behavior in the short-term. The results of this study highlight that demand-side management cannot be the only lever used to address Taiwan's forecasted decrease in electricity supply.

  10. Effects of Home Energy Management Systems on Distribution Utilities and Feeders Under Various Market Structures: Preprint

    2015-07-17

    The combination of distributed energy resources (DER) and retail tariff structures to provide benefits to both utility consumers and the utilities is poorly understood. To improve understanding, an Integrated Energy System Model (IESM) is being developed to simulate the physical and economic aspects of DER technologies, the buildings where they reside, and feeders servicing them. The IESM was used to simulate 20 houses with home energy management systems on a single feeder under a time of use tariff to estimate economic and physical impacts on both the households and the distribution utilities. HEMS reduce consumers’ electric bills by precooling houses in the hours before peak electricity pricing. Household savings are greater than the reduction utility net revenue indicating that HEMS can provide a societal benefit providing tariffs are structured so that utilities remain solvent. Utilization of HEMS reduce peak loads during high price hours but shifts it to hours with off-peak and shoulder prices and resulting in a higher peak load.

    2000-01-01

    The economic impact of electricity tariff rates on the residential sector of Yerevan, Armenia, is examined. The effect of tariff design on revenue generation and equity measures is considered, and the combination of energy pricing and compensatory social policies which provides the best mix of efficiency and protection for poor households is examined. An equity measure is defined in terms of a cumulative distribution function which describes the percent of the population that spends x percent or less of their income on electricity consumption. An optimal (Pareto-efficient) tariff is designed based on the analysis of survey data and an econometric model, and the Armenian tariff rate effective 1 January 1997 to 15 September 1997 is shown to be non-optimal relative to this rate. 22 refs

    International Nuclear Information System (INIS)

    Alavoine, Ivoa; Veyrenc, Thomas

    2008-01-01

    In this article, the authors first outline that regulated electricity tariffs trend to crystallize oppositions between European and national political legitimacies. In this respect, they comment the obviously diverging and incompatible positions of France and of the European Union on the regulation of electricity prices: legal procedures against France exist for a defect of transposition of a European directive; another procedure concerns the control of State subsidies; France has maintained a tariff regulation. The authors outline that these oppositions will have to be solved by national and European judges, and then comment that this opposition is related to the strong attachment of France to a tariff system built as a protection against European harmonisation: tariffs are considered as the most efficient and fairest regulation system

    Mobile telecommunication operators routinely charge subscribers lower prices for calls on their own network than for calls to other networks (on-net discounts). Studies on tariff-mediated network effects suggest this is due to large operators using on-net discounts to damage smaller rivals.

  15. Bairoch revisited : tariff structure and growth in the late 19th century

    OpenAIRE

    Tena Junguito, Antonio

    2008-01-01

    This paper revisits Bairoch’s hypothesis that in the late 19th century tariffs were positively associated with growth, as recently confirmed by a new generation of quantitative studies (see O`Rourke (2000), Jacks (2006) and Clemens-Williamson (2002, 2004)). This paper highlights the importance of the structure of protection in the relation between trade policy and its potential growth-promoting impact. Evidence is based on a new database on industrial tariffs for the 1870`s. The results show ...

  16. How Important Are Non-Tariff Barriers to Agricultural Trade within ECOWAS?

    OpenAIRE

    Seck, Abdoulaye; Cissokho, Lassana; Makpayo, Kossi; Haughton, Jonathan

    2010-01-01

    It is widely believed that the countries of Africa trade relatively little with the outside world, and among themselves, despite an extensive network of regional trade agreements. We examine this proposition by focusing on agricultural trade. Specifically, we ask whether non-tariff barriers (NTBs) are stunting agricultural trade within ECOWAS, a grouping of 15 countries in West Africa that has removed tariffs on agricultural trade among its members. Our survey of truckers in Tambacounda (Sene...

  17. Tariff Policy Towards a Monopolist in the Presence of Persuasive Advertising

    OpenAIRE

    Leahy, Dermot

    1992-01-01

    This paper considers the positive and normative aspects of tariffs and advertising taxes in a situation in which a foreign monopolist chooses advertising as well as output. On the positive side it is shown that under certain circumstances a tariff will induce a fall in the domestic consumer price of the import. On the normative side the paper demonstrates that an import subsidy can be optimal under two different specifications of the welfare function.

  18. European industrial policy as a non-tariff barrier

    Directory of Open Access Journals (Sweden)

    Gilberto Sarfati

    1998-05-01

    Full Text Available This article explores the contradictions between the EU and EU national states industrial policies and the Single Market program of elimination of NTBs (non-tariff barriers. The scope of NTBs connected to European industrial policy is divided into two spheres: the first are barriers on the level of Member States and the second are barriers on the EU level. On the national level, after the 1992 programme, the EU Member States continued to adopt many technical national regulations. On the EU level measures such as new standards, environment and anti-dumping rules, as well as Community expenditures in the different funds constitute new NTBs. Moreover, external competitors have to face other NTBs, such as VERs (Voluntary export restrictions, biased rules on public procurement, ecolabeling, and limitations on ownership, among other barriers. In this essay I demonstrate that the EU and the European national states run an active, unofficial industrial policy that distort the internal and external competition. The paper concludes that the EU industrial policy is not harmonized with the Single Market.

  19. Innovative Feed-In Tariff Designs that Limit Policy Costs

    Energy Technology Data Exchange (ETDEWEB)

    Kreycik, C.; Couture, T. D.; Cory, K. S.

    2011-06-01

    Feed-in tariffs (FITs) are the most prevalent renewable energy policy used globally to date, and there are many benefits to the certainty offered in the marketplace to reduce development risks and associated financing costs and to grow the renewable energy industry. However, concerns over escalating costs in jurisdictions with FIT policies have led to increased attention on cost control in renewable energy policy design. In recent years, policy mechanisms for containing FIT costs have become more refined, allowing policymakers to exert greater control on policy outcomes and on the resulting costs to ratepayers. As policymakers and regulators in the United States begin to explore the use of FITs, careful consideration must be given to the ways in which policy design can be used to balance the policies' advantages while bounding its costs. This report explores mechanisms that policymakers have implemented to limit FIT policy costs. If designed clearly and transparently, such mechanisms can align policymaker and market expectations for project deployment. Three different policy tools are evaluated: (1) caps, (2) payment level adjustment mechanisms, and (3) auction-based designs. The report employs case studies to explore the strengths and weaknesses of these three cost containment tools. These tools are then evaluated with a set of criteria including predictability for policymakers and the marketplace and the potential for unintended consequences.

  20. Analysis of carbon mitigation policies. Feed-in tariffs, energy and carbon price interactions and competitive distortions on carbon markets

    Energy Technology Data Exchange (ETDEWEB)

    2011-07-19

    I study several policy instruments for carbon mitigation with a focus on subsidies for renewable energies, emission taxes and emission allowances. In Chapter 1, I analyze the optimal design and the welfare implications of two policies consisting of an emission tax for conventional fossil-fuel utilities combined with a subsidy for the producers of renewable energy equipment and an emission tax combined with a feed-in tariff for renewable electricity. In Chapter 2 I study the empirical interrelationships between European emission allowance prices and prices for electricity, hard coal and natural gas with an application to portfolio allocation. In Chapters 3 and 4, I discuss several policy-related issues of emissions trading, in particular the potential for market manipulations by firms holding a dominant position in the emission market, the output market or both, and competitive distortions and leakage due to unequal emission regulations across industries, sectors, regions, or countries.

  2. Effect of tariffs on the performance and economic benefits of PV-coupled battery systems

    International Nuclear Information System (INIS)

    Parra, David; Patel, Martin K.

    2016-01-01

    Highlights: • Pb-acid and Li-ion batteries are compared under three different retail tariffs. • The battery ageing, i.e. capacity and discharge capability reduction is simulated. • A dynamic tariff (1-h resolution) increases the battery discharge value up to 28%. • A Li-ion cost of 375 CHF/kW h is required for Geneva for PV energy time-shift. • This requirement becomes 500 CHF/kW h if demand peak-shaving is also performed. - Abstract: The use of batteries in combination with PV systems in single homes is expected to become a widely applied energy storage solution. Since PV system cost is decreasing and the electricity market is constantly evolving there is marked interest in understanding the performance and economic benefits of adding battery systems to PV generation under different retail tariffs. The performance of lead-acid (PbA) and lithium-ion (Li-ion) battery systems in combination with PV generation for a single home in Switzerland is studied using a time-dependant analysis. Firstly, the economic benefits of the two battery types are analysed for three different types of tariffs, i.e. a dynamic tariff based on the wholesale market (one price per hour for every day of the year), a flat rate and time-of-use tariff with two periods. Secondly, the reduction of battery capacity and annual discharge throughout the battery lifetime are simulated for PbA and Li-ion batteries. It was found that despite the levelised value of battery systems reaches up to 28% higher values with the dynamic tariff compared to the flat rate tariff, the levelised cost increases by 94% for the dynamic tariff, resulting in lower profitability. The main reason for this is the reduction of equivalent full cycles performed with by battery systems with the dynamic tariff. Economic benefits also depend on the regulatory context and Li-ion battery systems were able to achieve internal rate of return (IRR) up to 0.8% and 4.3% in the region of Jura (Switzerland) and Germany due to

  4. Investigating preferences for dynamic electricity tariffs: The effect of environmental and system benefit disclosure

    International Nuclear Information System (INIS)

    Buryk, Stephen; Mead, Doug; Mourato, Susana; Torriti, Jacopo

    2015-01-01

    Dynamic electricity pricing can produce efficiency gains in the electricity sector and help achieve energy policy goals such as increasing electric system reliability and supporting renewable energy deployment. Retail electric companies can offer dynamic pricing to residential electricity customers via smart meter-enabled tariffs that proxy the cost to procure electricity on the wholesale market. Current investments in the smart metering necessary to implement dynamic tariffs show policy makers’ resolve for enabling responsive demand and realizing its benefits. However, despite these benefits and the potential bill savings these tariffs can offer, adoption among residential customers remains at low levels. Using a choice experiment approach, this paper seeks to determine whether disclosing the environmental and system benefits of dynamic tariffs to residential customers can increase adoption. Although sampling and design issues preclude wide generalization, we found that our environmentally conscious respondents reduced their required discount to switch to dynamic tariffs around 10% in response to higher awareness of environmental and system benefits. The perception that shifting usage is easy to do also had a significant impact, indicating the potential importance of enabling technology. Perhaps the targeted communication strategy employed by this study is one way to increase adoption and achieve policy goals. - Highlights: • We evaluate preferences for domestic dynamic electricity tariffs in the US and EU. • We use an online choice experiment approach with two dynamic tariff options. • People are more likely to switch if shown environmental and system benefits. • People are more likely to switch if they find shifting demand easy to do. • Our results imply the importance of targeted communication and enabling technology

  11. Encouraging vehicle-to-grid (V2G) participation through premium tariff rates

    Science.gov (United States)

    Richardson, David B.

    2013-12-01

    The provision of vehicle-to-grid (V2G) services to an electric grid by electric vehicles (EVs) can potentially reduce the cost of vehicle ownership through revenue generation. Recent studies indicate that yearly vehicle profit from V2G may not be sufficient to induce widespread participation. This paper investigates the feasibility of a premium tariff rate for V2G power, similar to current feed-in-tariff (FIT) programs for renewable energy. Using Ontario, Canada as a case study, an hourly time-series model for a fleet of commuter EVs is created. Tariff rates for V2G peak power are calculated based on the same return on investment as the current FIT for renewable energy in Ontario. The tariff rates are competitive with the renewable energy tariffs, especially when EVs are allowed to provide ancillary services to the grid in addition to peak power. Despite the guaranteed rate of return, yearly vehicle profit is low. Two variations are considered to increase vehicle profit, thereby enhancing the attractiveness of V2G. A higher return on investment is favored over direct benefits offered to EV owners. A higher return on investment may be justifiable based on the higher level of risk inherent in V2G when compared to renewable energy.

  12. Electricity tariff systems for informatics system design regarding consumption optimization in smart grids

    Directory of Open Access Journals (Sweden)

    Simona Vasilica OPREA

    2016-01-01

    Full Text Available High volume of data is gathered via sensors and recorded by smart meters. These data are processed at the electricity consumer and grid operators' side by big data analytics. Electricity consumption optimization offers multiple advantages for both consumers and grid operators. At the electricity customer level, by optimizing electricity consumption savings are significant, but the main benefits will come from indirect aspects such as avoiding onerous grid investments, higher volume of renewable energy sources' integration, less polluted environment etc. In order to optimize electricity consumption, advanced tariff systems are essential due to the financial incentive they provide for electricity consumers' behaviour change. In this paper several advanced tariff systems are described in details. These systems are applied in England, Spain, Italy, France, Norway and Germany. These systems are compared from characteristics, advantages/disadvantages point of view. Then, different tariff systems applied in Romania are presented. Romanian tariff systems have been designed for various electricity consumers' types. Different tariff systems applied by grid operators or electricity suppliers will be included in the database model that is part of an informatics system for electricity consumption optimization.

    Gipe, P.

    2007-11-01

    The Ontario Sustainable Energy Association (OSEA) promotes the development of community-owned renewable energy generation. It was emphasized that in order to achieve OSEA's original objectives of developing as much renewable energy as quickly as possible through community participation, changes are needed to Ontario's groundbreaking standard offer contract (SOC) program. This report examined the status of Ontario's SOC program and proposed changes to the program as part of the program's first two-year review. The report provided a summary of the program and discussed each of the program's goals, notably to encourage broad participation; eliminate barriers to distributed renewable generation; provide a stable market for renewable generation; stimulate new investment in renewable generation; provide a rigorous pricing model for setting the tariffs; create a program applicable to all renewable technologies; provide a simple, streamlined, and cost-effective application process; and provide a dispute resolution process. The program goals as developed by the Ontario Power Authority and Ontario Energy Board were discussed with reference to mixed results to date; simplicity; removing barriers; balancing targets with value to ratepayers; and building on the efforts of OSEA. Advanced renewable tariffs (ART) and tariff determination was also discussed along with ART's in Germany, France, Spain and Ontario. Inflation indexing; tariff degression; proposed new tariffs by technology; and other costs and factors affecting profitability were also reviewed. ref., tabs

    2014-01-01

    Using an agent-based modeling approach we study the temporal dynamics of consumer opinions regarding switching to dynamic electricity tariffs and the actual decisions to switch. We assume that the decision to switch is based on the unanimity of τ past opinions. The resulting model offers a hypothetical, yet plausible explanation of why there is such a big discrepancy between consumer opinions, as measured by market surveys, and the actual participation in pilot programs and the adoption of dynamic tariffs. We argue that due to the high indifference level in today's retail electricity markets, customer opinions are very unstable and change frequently. The conducted simulation study shows that reducing the indifference level can result in narrowing the intention–behavior gap. A similar effect can be achieved by decreasing the decision time that a consumer takes to make a decision. - Highlights: • We propose an agent-based model to study the adoption of dynamic electricity tariffs. • The decision to change the tariff is based on the unanimity of τ past opinions. • The model explains why the empirically observed intention–behavior gap exists. • The adoption of dynamic tariffs is impossible due to the high level of indifference in today's societies. • Reducing the indifference level or decreasing the decision time can result in narrowing the gap

    2014-05-01

    Full Text Available This study estimates health utilities (HU in Sweden for a range of type 2 diabetes-related complications using EQ-5D and two alternative tariffs (UK and Swedish from 1757 patients with type 2 diabetes from the Swedish National Diabetes Register (NDR. Ordinary least squares were used for statistical analysis. Lower HU was found for female gender, younger age at diagnosis, higher BMI, and history of complications. Microvascular and macrovascular complications had the most negative effect on HU among women and men, respectively. The greatest decline in HU was associated with kidney disorders (−0.114 using the UK tariff and stroke (−0.059 using the Swedish tariff. Multiple stroke and non-acute ischaemic heart disease had higher negative effect than a single event. With the UK tariff, each year elapsed since the last microvascular/macrovascular complication was associated with 0.013 and 0.007 units higher HU, respectively. We found important heterogeneities in effects of complications on HU in terms of gender, multiple event, and time. The Swedish tariff gave smaller estimates and so may result in less cost-effective interventions than the UK tariff. These results suggest that incorporating subgroup-specific HU in cost-utility analyses might provide more insight for informed decision-making.

  18. Import Tariffs of Trading Partners: Evidence from Three West Balkan Countries

    2017-12-01

    Full Text Available This paper aims to examine the effect of reducing the import tariffs of trading partners on total and individual exports of products from three countries of the Western Balkans and individually observed for each country. In order to investigate the potential effect, this paper applied the gravity equation and the GMM model system dynamic data estimation. The research is based on aggregate and non‑aggregate approach. Within the aggregate approach for the three countries of the Western Balkans, the reduction of import simple average tariff rate (SAT and weighted average tariff (WAT rate have a positive effect on the growth of total and individual exports of products. Within the non‑aggregate approach for each country individually, the reduction in imports of SAT and WAT rates also have a positive effect on the growth of total and individual exports of products from Albania and Serbia, while this effect is weak for FYR Macedonia.

    Full Text Available In this paper we analyze the problem of identification of a tariff for a Fire & Theft Car policy for Insurance Companies. Usually companies obtain this tariff by empirical estimate of the pure rate by evaluating the impact of some personalization variables. In this paper we propose the usage of a semi-parametric Cox model, where the response variable is not the waiting time until an event, but the degree of damage because of theft or fire of a car. The proposed model allows to easily tackle typical problems in data available to the companies, like the presence of franchises, which are treated as censored data.

    Large shares of variable renewable energy (VRE), requires flexibility solutions are developed. Considerable flexibility potentials exist from large consumers, e.g. power-to-heat (P2H) in district heating (DH). However, the existing grid tariffs obliterate the price signals from the wholesale...... designs that facilitate more flexible energy demand of DH operators.

    2008-01-01

    This study examines the impacts of increasing electricity tariff to the long run marginal cost on prices of other products using a static input-output approach. It is found that such an increase would drive up the prices of all other products. Although the aggregate price impact from such an increase is not large, it would be socially difficult to implement this increase at one time, particularly given that Vietnam is facing high inflation rate. A roadmap for electricity tariff increase is thus discussed

  5. Customs tariffs and the policy of custom tariffs in the function of the realization of regional economic integrations: The example of the European Union

    Directory of Open Access Journals (Sweden)

    Vranješ Mile

    2012-01-01

    Full Text Available Custom tariffs and the policy of custom tariffs have always been important instruments in the protection of domestic production from foreign competition, though the more in the past, the less in today's global economic environment. The idea of protectionism in international trade hasn't evaded the European Union either. The European Union has a common protectionist policy against countries that are not member to it. The agricultural production and the policy of administrative levies on the import of agricultural products pertain to the area that enjoys the highest degree of protection. The realization of such protectionist policy makes the international trade less free, while the free movement of goods is quintessential to the economic growth of the European Union, other regional economic integrations, individual countries and the society as such. The World Trade Organization, which imposes its own rules on the international trade, the creation of regional economic organizations in today's environment of international trade and free-trade agreements between individual states shrank to minimal the diapason of various protectionist measures and instruments. The decline of the idea of protectionism in international trade is evidenced by data on the share of the customs tariffs in the total fiscal revenues of the European Union and of the GDP of the member states. Namely, the fiscal impact of custom tariffs for some years shows a descending tendency, above all due to the process of globalization in foreign trade and liberalization at the scale of global economy. The European Union will be able to facilitate the development of the regional economic integrations only through the liberalization of foreign trade, because the idea of protectionism in international trade doesn't have perspectives on the long run.

    While the influence of nature (genes) and nurture (environment) on elite sporting performance remains difficult to precisely determine, the dismissal of either as a contributing factor to performance is unwarranted. It is accepted that a complex interaction of a combination of innumerable factors may mold a talented athlete into a champion. The prevailing view today is that understanding elite human performance will require the deciphering of two major sources of individual differences, genes...

  17. Effects of a Tariff Reduction on Grain Self-Sufficiency: Evidence from Country-Level Panel Data

    Directory of Open Access Journals (Sweden)

    Younghyeon Jeon

    2017-10-01

    Full Text Available This paper investigates the effects of a tariff reduction on the grain self-sufficiency and the sustainability of domestic grain production. We develop a theoretical model in which trade, tariff, and supply-demand equations are explicitly included, with the classification of food importing and exporting countries. Estimation results based on panel data for 150 countries over 17 years show that the effects of domestic tariff of food-importing countries on the grain self-sufficiency rate (SSR are positive. This implies that market expansion through tariff reduction will have a negative effect on the importing country’s food SSR and sustainable domestic supply. Using the estimated coefficients on the empirical equations, we derived the elasticities of grain SSR with respect to the tariff rate of food-importing countries. Those are in the ranges of 0.221–0.387.

  18. The suitability of a feed-in tariff for wind energy in New Zealand—A study based on stakeholders' perspectives

    International Nuclear Information System (INIS)

    Schaefer, Manuel S.; Lloyd, Bob; Stephenson, Janet R.

    2012-01-01

    New Zealand (NZ) aims to expand the deployment of wind energy as one means to achieve 90% of electricity generation from renewables by 2025 and in addition to reduce green house gas (GHG) emissions. Due to electricity market regulations that inhibit market entry for independent developers, New Zealand's wind energy development has been limited to primarily large wind farms developed by a handful of electricity utilities. In contrast to many other countries, NZ lacks policy support for entry of smaller investors into the wind generation sector. In order to gage the acceptability of a feed in tariff (FIT) for wind energy in New Zealand, a survey questionnaire (366 respondents) with land owning farmers and semi structured interviews with wind energy stakeholders was conducted. Although international literature suggests that a FIT would be the most suitable policy support scheme to accelerate wind energy deployment, this conclusion was not reached by many influential stakeholders in NZ. However, a majority of the surveyed farmers supported the introduction of a FIT for wind energy. The study also revealed that farmers' acceptance of wind energy in their local area increases with their awareness about climate change issues. - Highlights: ► Of countries in the world with a good wind regime, NZ has a low level of policy support for wind energy. ► A survey of landowning farmers in NZ (366 respondents) indicated support for a feed in tariff for wind energy. ► The major electricity generators, however, did not indicate support for a feed in tariff. ► A low level of recognition of climate change being anthropogenic was found among landowning farmers.

  4. Assessment of the feed-in tariff mechanism for renewable energies in Taiwan

    International Nuclear Information System (INIS)

    Huang, Yun-Hsun; Wu, Jung-Hua

    2011-01-01

    Due to Taiwan's lack of natural resources, dependence on imported energy, and pursuit of sustainable development, renewable energies are extremely important for Taiwan's future energy supply. Since Taiwan's feed-in tariff (FIT) is still in its initial stage, one must examine whether the current system is compatible with a well-designed FIT scheme. This study examines the main features of Taiwan's FIT system and assesses design options using several criteria. Additionally, one of the most important elements of a FIT scheme, namely, a tariff system, is discussed. Taiwan's FIT scheme has the design options required by well-functioning FITs, and the guaranteed-return tariff system coincides with the spirit underlying leading global FITs; however, many issues, such as setting goals by stages, refinement of the tariff calculation methodology, and elimination of other non-economic barriers, must be addressed to achieve future developmental goals and green industry growth. - Highlights: ► No in-depth study has focused exclusively on Taiwan's FIT design options. ► This study fills this gap in the literature by examining Taiwan's FIT system. ► Assessments demonstrate that Taiwan's FIT scheme has the design options required by well-functioning FITs. ► Four issues are identified that Taiwan's policy makers should address to achieve future developmental goals and expand green industries.

  6. The tariffs of use of liquefied natural gas transportation networks and facilities

    International Nuclear Information System (INIS)

    2005-01-01

    The new tariff proposals for the use of natural gas transportation networks were transmitted to the French Ministry of economy, finances and industry on October 27, 2004 by the commission of energy regulation. These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

  8. The solar photovoltaic feed-in tariff scheme in New South Wales, Australia

    International Nuclear Information System (INIS)

    Martin, Nigel; Rice, John

    2013-01-01

    Solar Photovoltaic (PV) electricity systems are part of Australia's energy supply matrix. In the case of New South Wales (NSW), the state government has had to deal with a complex policy problem. In order to play its role in the federal Small-scale Renewable Energy Scheme, the NSW government initiated the 7 year Solar Bonus Scheme in 2010. However, in attempting to maximise community investment in small-scale solar PV systems, it relied on faulty financial modelling that applied a generous Feed-in Tariff (FiT) and underestimated the level of investor participation and installed capacity. Consequently, the scheme has resulted in very high public costs that will require policy changes that bring investors and energy retailers into conflict, and unpopular electricity retail price adjustments. This paper uses a structured case and stakeholder analysis to critically analyse the FiT policy, while also highlighting important lessons for policymakers engaging in FiT design. - highlights: • Describes the design of a feed-in tariff policy for solar PV electricity exports. • Exposes a A$1 billion payment overrun and weaknesses in policy controls. • Identifies policy design flaws and opportunities to improve future tariff designs. • Discusses the importance of developing nationally integrated feed-in tariff policies

  12. How much do electricity tariff increases in Ukraine hurt the poor?

    International Nuclear Information System (INIS)

    Dodonov, B.; Pfaffenberger, W.

    2004-01-01

    Increasing the electricity tariffs for private consumers to cost-covering levels has been a very sensitive issue for all transition countries. The likely negative social consequences are the central argument why the necessary tariff corrections have not yet been implemented in Ukraine by the political decision makers. Since official data is not available, there is insufficient knowledge regarding the electricity consumption behaviour of private households. This makes it difficult to counter the official arguments with hard evidence. A survey was carried out by the authors giving a more detailed picture. Basic data of the survey was used in evaluating the impact of possible tariff increases on the household expenditures of different income groups, using both the compensating (CV) and the equivalent variation (EV) methods. The findings confirm that an electricity tariff increase up to the level which would cover ''officially'' measured costs, as defined by the Ukrainian electricity regulatory authority, would not cause severe social problems. However, further increases up to a level, which would cover the ''true'' costs, i.e. up to a level comparable to the average OECD level, should only be realised in steps. (author)

  3. Cost and optimal feed-in tariff for small scale photovoltaic systems in China

    International Nuclear Information System (INIS)

    Rigter, Jasper; Vidican, Georgeta

    2010-01-01

    China has recently become a dominant player in the solar photovoltaic (PV) industry, producing more than one-third of the global supply of solar cells in 2008. However, as of 2008, less than 1% of global installations were based in China. Recently, the government has stated its grand ambitions of expanding the share of electricity derived from solar power. As part of this initiative, policy makers are currently in the process of drafting a feed-in tariff policy to support the development of the solar energy market. In this paper, we aim to calculate what the level of such a tariff should be. We develop a closed form equation for the cost of PV, and use forecasts on prices of solar systems to derive an optimal feed-in tariff, including a digression rate. The focus is on the potential of residential and small scale commercial solar PV installations. We show that the cost of small scale PV in China has decreased rapidly during the period 2005-2009. Our analysis also shows that optimal feed-in tariffs vary widely between regions within China, and that grid parity could be reached in large parts of the country depending on the expected escalation in electricity prices.

  4. Estimating the option value of a non-firm electricity tariff

    International Nuclear Information System (INIS)

    Moore, J.; Horii, B.; Price, S.; Olson, A.; Woo, C.K.

    2010-01-01

    We estimate the option value of a non-firm electricity tariff commonly used by a local distribution company (LDC) in its electricity demand response program. This option value captures the benefit that a LDC enjoys from not serving an end-use load during high-price hours in a wholesale electricity market. It is conservative in that it does not include the cost savings in meeting the LDC's resource adequacy requirement or deferring transmission and distribution (T and D) investments necessary for delivering reliable service. Illustrated by a Northern California example, our two-pronged approach entails (a) a set of summer monthly market price regressions to forecast daily spot price distributions that incorporate uncertainty in natural gas price and weather; and (b) a simulation exercise to quantify the tariff's value under a specific design. The results indicate that a non-firm service tariff can have varying option value estimates that are highly sensitive to the tariff's design, and that an incentive payment based on the option value alone is likely insufficient to attract customer participation in a non-firm service program.

Any electric utility affiliates that own or control generation must not have market power in the relevant market, which is defined as the utility`s first-tier markets. One can prove that its affiliates do not have generation dominance by: (a) showing that its entire generating capacity is committed under long term contract, (b) showing that its affiliates already are authorized to sell at market-based rates, or (c) submitting a market analysis which demonstrates that the affiliates do not possess generation market power. The electric utility affiliates must have a transmission tariff on file which provides for comparable transmission services. The APM must agree not to buy power from, or sell power to its electric utility affiliate without prior approval by the Federal Energy Regulatory Commission (FERC). The APM must notify FERC if it sells power to, buys power from, or obtains transmission service from a utility that has any business relationship with any affiliates. Any non-sales services provided by the utility affiliates must not be priced below market value. Procedures must ensure that market information is not shared between the utility and the APM, or shared on a comparable basis with non-affiliates. A continuing obligation exists for the APM to notify FERC of any change in these criteria occurring after approval is granted. Concerns with these provisions and suggested improvements are discussed.

  14. Method for a national tariff comparison for natural gas, electricity and heat. Set-up and presentation

    International Nuclear Information System (INIS)

    1998-05-01

    Several groups (within distribution companies and outside those companies) have a need for information and data on energy tariffs. It is the opinion of the ad-hoc working group that a comparison of tariffs on the basis of standard cases is the most practical method to meet the information demand of all the parties involved. Those standard cases are formulated and presented for prices of electricity, natural gas and heat, including applied consumption parameters. A comparison of such tariffs must be made periodically

  15. Tariff advice for the supply of heat to small-scale consumers in 1999

    International Nuclear Information System (INIS)

    1998-12-01

    The title advice is based on the principle of 'not more than otherwise' (nmda, abbreviated in Dutch), which principle is applied for the calculation of the contribution for connection to the energy supply system, the reduced rate for those paying standing charges, and the price of heat. The principle implies that the determined tariff for the supply of heat is such that, on average, the consumer of heat does not pay more than in case natural gas is used for an individual central heating system. In his advice attention is paid to the connection contribution, the reduced rate, and the heat price. In the final chapter the indexation and updating of the different tariff elements of the advice are discussed

    Full Text Available In this paper, I discuss the effects of certain trade policy measures, mostly import tariffs, presently contemplated by the US government, aimed at enhancing domestic employment in a number of targeted industries. I intend to show that insofar as such measures restrain free trade among NAFTA member-countries, they run counter to a basic rule suggested by conventional theory, stating that, following changes in the tariff structure, resources will shift toward activities that enjoy the highest rate of effective protection. I try to demonstrate that erecting barriers against inside-NAFTA trade, aside from hurting industries that use outsourcing extensively, has little chances to create incentives for labor shifts in the desired direction.

    Gaymard, Herve; Valter, Clotilde

    2015-01-01

    This huge report first proposes a critical overview of the current French electricity tariff system and a new arrangement. In this overview, the authors indicate the various objectives of this tariff: to cover the costs of electricity providers, to cover the costs of grid managers, to ensure the geographical equalization of electricity price, to preserve the household purchasing power, to favour enterprise competitiveness, to implement energy transition, to influence user energy consumption, to make available financial resources for local communities and State, and to finance pensions of staff of electricity and gas industries. They describe the current situation which can be defined as an end of a monopoly without any actual competition: salami slicing of the electricity sector, a marginal and costly competition (limited opening to competition, price increase instead of decrease). They also describe the situation of EDF, its evolution from a golden age to a critical situation, a financial situation on a razor's edge, an incoherent and disturbing State. They present the European legal framework as unanimously contested, and the main challenges of energy transition. Then, the authors describe how to introduce coherence in the tariff system again: by giving means to EDF to face future challenges (by clarifying the State's position, by decreasing EDF's costs, by enabling EDF to play leading role in the world in the field of low-carbon energies), by supporting an integrated vision of a Europe of electricity (by developing a more ambitious European framework), and by revising the electricity tariff structure. The many hearings of various actors of the electricity and energy sectors are reported (these actors belong to public bodies, energy companies, professional associations, consumer associations, and so on)

    New tariffs of gas transportation networks usage will be enforced on January 1, 2009. They will greatly simplify the access to transportation networks, favorable to the development of competition, and will allow market actors to have a better visibility. They represent a favorable framework for investments on the transportation network and will incite the gas suppliers to improve their quality of service and to control their expenses. (J.S.)

    Full Text Available The suicide has existed throughout history and has prevailed as a behavior that was contrary to the rules of the society in terms of preservation of life itself; the objective of this research was to make emphasis on the nature of antisocial behavior of this behavior and show its prevalence in the years 2006 to 2010 in Mexico and Tamaulipas, as well as from 1999 to 2008 in Reynosa, Tamaulipas. For which the data were obtained from the National Institute of Statistics and Geography to the country and the State and the books of the register of deaths by cause violent of the Regional Unit of Expert Services of the Attorney General of Justice, which has its headquarters in Reynosa; developed a theoretical framework on the impact of the conduct in society and the means to prevent it, The data obtained we revealed the continued presence of this conduct year-on-year, 23.554 cases appearing in Mexico and 819 in Tamaulipas in the period from 2006 to 2010; in Reynosa, Tamaulipas were presented 278 suicides in the period 1999 to 2008. The results show us a conduct stable in numbers, but without excessive overflows that prevails year-on-year, suicide, and the attempt of the same should be viewed as a social problem and not detract from the importance that it deserves a conduct of these dimensions, that is no more than a reflection of the situation in which are the means of social control toward the preservation of life itself.

  2. Assessing DRG cost accounting with respect to resource allocation and tariff calculation: the case of Germany

    Science.gov (United States)

    2012-01-01

    The purpose of this paper is to analyze the German diagnosis related groups (G-DRG) cost accounting scheme by assessing its resource allocation at hospital level and its tariff calculation at national level. First, the paper reviews and assesses the three steps in the G-DRG resource allocation scheme at hospital level: (1) the groundwork; (2) cost-center accounting; and (3) patient-level costing. Second, the paper reviews and assesses the three steps in G-DRG national tariff calculation: (1) plausibility checks; (2) inlier calculation; and (3) the “one hospital” approach. The assessment is based on the two main goals of G-DRG introduction: improving transparency and efficiency. A further empirical assessment attests high costing quality. The G-DRG cost accounting scheme shows high system quality in resource allocation at hospital level, with limitations concerning a managerially relevant full cost approach and limitations in terms of advanced activity-based costing at patient-level. However, the scheme has serious flaws in national tariff calculation: inlier calculation is normative, and the “one hospital” model causes cost bias, adjustment and representativeness issues. The G-DRG system was designed for reimbursement calculation, but developed to a standard with strategic management implications, generalized by the idea of adapting a hospital’s cost structures to DRG revenues. This combination causes problems in actual hospital financing, although resource allocation is advanced at hospital level. PMID:22935314

  3. The impact of further tariff reduction on the EU sugar sector in the forthcoming multilateral round

    2008-12-01

    Full Text Available This paper indicates the need for reform in the EU sugar sector due to the erosion of "border protection" in the view of further reduction in import tariffs for sugar. Three tariff reduction methods are assessed to project the "border protection" for EU sugar: Swiss formula proposed by the Cairns Group, "Harbinson" Proposal by the World Trade Organization and Uruguay Round formula proposed by the EU. In the assumed forthcoming multilateral round for agriculture, the EU would need to lower the support price for sugar by 67%, if the Cairns Group tariff reduction method is used. However, if the "Harbinson" method is used, the EU would need to lower the support price for sugar by at least 35%. On the contrary, the EU may avoid lowering the support price for sugar with three conditions occurring simultaneously: 1 the Uruguay Round formula is used as the reduction method in the assumed new WTO round and the EU can use the minimum reduction rate of 15% for sugar

  4. Tariff-based incentives for improving coal-power-plant efficiencies in India

    Improving the efficiency of coal-based power plants plays an important role in improving the performance of India's power sector. It allows for increased consumer benefits through cost reduction, while enhancing energy security and helping reduce local and global pollution through more efficient coal use. A focus on supply-side efficiency also complements other ongoing efforts on end-use efficiency. The recent restructuring of the Indian electricity sector offers an important route to improving power plant efficiency, through regulatory mechanisms that allow for an independent tariff setting process for bulk purchases of electricity from generators. Current tariffs based on normative benchmarks for performance norms are hobbled by information asymmetry (where regulators do not have access to detailed performance data). Hence, we propose a new incentive scheme that gets around the asymmetry problem by setting performance benchmarks based on actual efficiency data, rather than on a normative basis. The scheme provides direct tariff-based incentives for efficiency improvements, while benefiting consumers by reducing electricity costs in the long run. This proposal might also be useful for regulators in other countries to incorporate similar incentives for efficiency improvement in power generation. (author)

    Full Text Available Thailand is targeted to reach 6,000 MW of total installed PV capacity by 2036. Feed-in tariff (FIT was one of the most successful PV mechanisms of Thailand for promoting PV generated electricity. The evaluation of the FIT models for PV in Thailand which was designed 3 models such as premium price FIT model (Adder in the first FIT policy to motivate attention on investment in PV power plant. After that used fixed price FIT model for PV ground-mounted and front-end loaded FIT model for solar rooftop. In addition to, Thailand has project-specific tariff design which FIT rates are differentiated tariff payment levels by technology, capacity size, and quality of the resource. As result of FIT policies, the PV installation is 1,287 MW of cumulative capacity in 2014. Furthermore, the financial evaluation of FIT for PV project in Thailand found that Net Present Value (NPV 32.97 million Baht, Internal Rate of Return (IRR 13.22%, payback period 8.86 years and B/C ratio was 1.66 which must be implemented in conjunction with other financial support measures such as low interest loans, tax benefits, etc. The several incentives to promote PV in Thailand especially FIT shown as PV projects are to be profitable and incentives to investors.

  6. Tariffs Can Be Structured to Encourage Photovoltaic Energy

    The solar power market is growing at a quickening pace, fueled by an array of national and local initiatives and policies aimed at improving the value proposition of customer-sited photovoltaic (PV) systems. Though these policies take many forms, they commonly include up-front capital cost rebates or ongoing production incentives, supplemented by net metering requirements to ensure that customer-sited PV systems offset the full retail rate of the customer-hosts. Somewhat less recognized is the role of retail rate design, beyond net metering, on the customer-economics of grid-connected PV. Over the life of a PV system, utility bill savings represent a substantial portion of the overall economic value received by the customer. At the same time, the design of retail electricity rates, particularly for commercial and industrial customers, can vary quite substantially. Understanding how specific differences in rate design affect the value of customer-sited PV is therefore essential to supporting the continued growth of this market.

  7. The transmission tariff - the economic tool for the network infrastructure development

    The free access to the transmission network is one of the key elements of the electricity market development both at the national and regional levels. The operation of the electricity market needs the appropriate development of its basic infrastructure, the transmission network. In the frame work of the electricity market, the network ensures the electricity transmission under reliable conditions, from the generators to the suppliers and eligible consumers and creates market opportunities for its users. One of the main market tools, which may influence the optimal development of the network structure, by an efficient location signal of the large consumers and generators, is the pricing system. The overall costs of the Transmission System Operator (TSO) for providing the transmission service may be distinctly focused by categories as follows: - Costs of the existing transmission network (fixed costs), maintenance and operation costs, capital costs; - Costs of electricity losses (variable costs); - Development costs needed to eliminate the network congestion (variable costs). The recovery of all costs involved by the transmission service is based on regulated tariff system approved by ANRE. By the tariff system, the transmission and system operator aims both to cover the transmission service cost and provide locational signals for all market players which should lead to the efficient grid operation as well as to the optimal development of its structure. The tariff values reflect the polarization existing in the Romanian Power System (PS), namely: surplus power in the South area of the PS (4G zone) and a power deficit in the North areas of the PS (2G and 5G zones). Electricity demand is more evenly distributed in the territory than the electricity generated. This assertion is based on the following statement: - the tariffs value range of electricity delivered in the transmission network is wider, between 1.13 and 2.39 USD/MWh (51%) than the one related to the zones of

  8. Molecular-based mechanisms of Mendelian forms of salt-dependent hypertension: questioning the prevailing theory.

    This critical review directly challenges the prevailing theory that a transient increase in cardiac output caused by genetically mediated increases in activity of the ENaC in the aldosterone sensitive distal nephron, or of the NCC in the distal convoluted tubule, accounts entirely for the hemodynamic initiation of all Mendelian forms of salt-dependent hypertension (Figure 1). The prevailing theory of how genetic mutations enable salt to hemodynamically initiate Mendelian forms of salt-dependent hypertension in humans (Figure 1) depends on the results of salt-loading studies of cardiac output and systemic vascular resistance in nongenetic models of hypertension that lack appropriate normal controls. The theory is inconsistent with the results of studies that include measurements of the initial hemodynamic changes induced by salt loading in normal, salt-resistant controls. The present analysis, which takes into account the results of salt-loading studies that include the requisite normal controls, indicates that mutation-induced increases in the renal tubular activity of ENaC or NCC that lead to transient increases in cardiac output will generally not be sufficient to enable increases in salt intake to initiate the increased BP that characterizes Mendelian forms of salt-dependent hypertension (Table). The present analysis also raises questions about whether mutation-dependent increases in renal tubular activity of ENaC or NCC are even necessary to account for increased risk for salt-dependent hypertension in most patients with such mutations. We propose that for the genetic alterations underlying Mendelian forms of salt-dependent hypertension to enable increases in salt intake to initiate the increased BP, they must often cause vasodysfunction, ie, an inability to normally vasodilate and decrease systemic vascular resistance in response to increases in salt intake within dietary ranges typically observed in most modern societies. A subnormal ability to vasodilate in

    Waste generated from construction and building demolition work constitutes about 68% of all solid waste generated each year in South East Queensland. Consequently, it has created a serious waste management problem. The State Governments of Victoria and New South Wales have been encouraging the use of recycled materials from construction and related waste; they have also promulgated specifications for their use. In Queensland, however, similar regulations are not anticipated in the near future, which explains the lack of funded research conducted in this important arena. This paper presents an evaluation of the prevailing waste recycling practices in Queensland. Nine sites were visited, including two construction sites, three demolition sites, three recycling plants and one landfill in South East Queensland. The difficulties encountered by the recycling programme operators and their associates at these sites are described and the benefits of recycling construction materials are presented. One of the major barriers is that the local councils disallow the use of recycled materials in new construction work. To help rectify these impediments to recycling, recommendations are given to increase the use of recycled construction waste in South East Queensland.

    Based on attempts to resolve the problem of various self contradictory assumptions behind the prevailing belief on single photon interference, we have analyzed the process steps behind our experimental measurements and named the process as the Interaction Process Mapping Epistemology (IPM-E). This has helped us recognize that the quantum mechanical Measurement Problem has a much universal and deeper root in nature. Our scientific theorization process suffers from a Perpetual Information Challenge (PIC), which cannot be overcome by elegant and/or sophisticated mathematical theories alone. Iterative imaginative application of IPM-E needs to be used as a metaphorical analytical continuation to fill up the missing information gaps. IPM-E has also guided us to recognize the generic NIW-principle (Non-Interaction of Waves) in the linear domain, not explicitly recognized in current books and literature. Superposition effects become manifest through light-matter interactions. Detecting dipoles gets stimulated by multiple superposed beams; it sums the simultaneous multiple stimulations into a single resultant undulation, which then guides the resultant energy exchange. The consequent transformation in the detector corresponds to observed fringes. They neither represent interference of light; nor represent selective arrival or non-arrival of photons on the detector. Photons do not possess any force of mutual interaction to generate their redistribution. Implementation of IPM-E requires us to recognize our subjective interpretation propensity with which we are burdened due to our evolutionary successes.

  11. Global empirical wind model for the upper mesosphere/lower thermosphere. I. Prevailing wind

    Y. I. Portnyagin

    Full Text Available An updated empirical climatic zonally averaged prevailing wind model for the upper mesosphere/lower thermosphere (70-110 km, extending from 80°N to 80°S is presented. The model is constructed from the fitting of monthly mean winds from meteor radar and MF radar measurements at more than 40 stations, well distributed over the globe. The height-latitude contour plots of monthly mean zonal and meridional winds for all months of the year, and of annual mean wind, amplitudes and phases of annual and semiannual harmonics of wind variations are analyzed to reveal the main features of the seasonal variation of the global wind structures in the Northern and Southern Hemispheres. Some results of comparison between the ground-based wind models and the space-based models are presented. It is shown that, with the exception of annual mean systematic bias between the zonal winds provided by the ground-based and space-based models, a good agreement between the models is observed. The possible origin of this bias is discussed.

    While the influence of nature (genes) and nurture (environment) on elite sporting performance remains difficult to precisely determine, the dismissal of either as a contributing factor to performance is unwarranted. It is accepted that a complex interaction of a combination of innumerable factors may mold a talented athlete into a champion. The prevailing view today is that understanding elite human performance will require the deciphering of two major sources of individual differences, genes and the environment. It is widely accepted that superior performers are endowed with a high genetic potential actualised through hard and prodigious effort. Heritability studies using the twin model have provided the basis to disentangle genetic and environmental factors that contribute to complex human traits and have paved the way to the detection of specific genes for elite sport performance. Yet, the heritability for most phenotypes essential to elite human performance is above 50% but below 100%, meaning that the environment is also important. Furthermore, individual differences can potentially also be explained not only by the impact of DNA sequence variation on biology and behaviour, but also by the effects of epigenetic changes which affect phenotype by modifying gene expression. Despite this complexity, the overwhelming and accumulating evidence, amounted through experimental research spanning almost two centuries, tips the balance in favour of nature in the "nature" and "nurture" debate. In other words, truly elite-level athletes are built - but only from those born with innate ability.

    Spiders represent an ancient predatory lineage known for their extraordinary biomaterials, including venoms and silks. These adaptations make spiders key arthropod predators in most terrestrial ecosystems. Despite ecological, biomedical, and biomaterial importance, relationships among major spider lineages remain unresolved or poorly supported. Current working hypotheses for a spider "backbone" phylogeny are largely based on morphological evidence, as most molecular markers currently employed are generally inadequate for resolving deeper-level relationships. We present here a phylogenomic analysis of spiders including taxa representing all major spider lineages. Our robust phylogenetic hypothesis recovers some fundamental and uncontroversial spider clades, but rejects the prevailing paradigm of a monophyletic Orbiculariae, the most diverse lineage, containing orb-weaving spiders. Based on our results, the orb web either evolved much earlier than previously hypothesized and is ancestral for a majority of spiders or else it has multiple independent origins, as hypothesized by precladistic authors. Cribellate deinopoid orb weavers that use mechanically adhesive silk are more closely related to a diverse clade of mostly webless spiders than to the araneoid orb-weaving spiders that use adhesive droplet silks. The fundamental shift in our understanding of spider phylogeny proposed here has broad implications for interpreting the evolution of spiders, their remarkable biomaterials, and a key extended phenotype--the spider web.

    The surface of most aerial plant organs is covered with a cuticle that provides protection against multiple stress factors including dehydration. Interest on the nature of this external layer dates back to the beginning of the 19th century and since then, several studies facilitated a better understanding of cuticular chemical composition and structure. The prevailing undertanding of the cuticle as a lipidic, hydrophobic layer which is independent from the epidermal cell wall underneath stems from the concept developed by Brongniart and von Mohl during the first half of the 19th century. Such early investigations on plant cuticles attempted to link chemical composition and structure with the existing technologies, and have not been directly challenged for decades. Beginning with a historical overview about the development of cuticular studies, this review is aimed at critically assessing the information available on cuticle chemical composition and structure, considering studies performed with cuticles and isolated cuticular chemical components. The concept of the cuticle as a lipid layer independent from the cell wall is subsequently challenged, based on the existing literature, and on new findings pointing toward the cell wall nature of this layer, also providing examples of different leaf cuticle structures. Finally, the need for a re-assessment of the chemical and structural nature of the plant cuticle is highlighted, considering its cell wall nature and variability among organs, species, developmental stages, and biotic and abiotic factors during plant growth.

    A fifth of UK households live in fuel poverty, with significant health risks. Recent government strategy integrates public health with local government. This study examined barriers to switching energy tariffs and the impact of an energy tariff switching 'intervention' on vulnerable peoples' likelihood to, success in, switching tariffs. Participatory Action Research (PAR), conducted in West London. Community researchers from three voluntary/community organisations (VCOs) collaborated in recruitment, study design, data collection and analysis. VCOs recruited 151 participants from existing service users in three groups: Black and Minority Ethnic (BME) communities, older people (>75 yrs) and families with young children. Researchers conducted two semi-structured interviews with each participant, a week apart. The first interview asked about demographics, current energy supplier, financial situation, previous experience of tariff-switching and barriers to switching. Researchers then provided the 'intervention' - advice on tariff-switching, printed materials, access to websites. The second interview explored usefulness of the 'intervention', other information used, remaining barriers and information needs. Researchers kept case notes and a reflective log. Data was analysed thematically and collaboratively between the research coordinator and researchers. Quantitative data was analysed using SPSS, with descriptive statistics and Chi-squared tests. A total of 151 people were interviewed: 47 older people over 75 years, 51 families with young children, 51 BME (two were missing demographics). The majority were not White British or UK-born. Average household weekly income was £230. Around half described 'difficult' financial situations, 94% were receiving state benefits and 62% were in debt. Less than a third had tried to find a better energy deal; knowledge was the main barrier. After the intervention 19 people tried to switch, 13 did. Young families were most likely to

  16. Assessing the strength and effectiveness of renewable electricity feed-in tariffs in European Union countries

    Jenner, Steffen; Groba, Felix; Indvik, Joe

    2013-01-01

    In the last two decades, feed-in tariffs (FIT) have emerged as one of the most popular policies for supporting renewable electricity (RES-E) generation. A few studies have assessed the effectiveness of RES-E policies, but most ignore policy design features and market characteristics (e.g. electricity price and production cost) that influence policy strength. We employ 1992–2008 panel data to conduct the first econometric analysis of the effectiveness of FIT policies in promoting solar photovoltaic (PV) and onshore wind power development in 26 European Union countries. We develop a new indicator for FIT strength that captures variability in tariff size, contract duration, digression rate, and electricity price and production cost to estimate the resulting return on investment. We regress this indicator on added RES-E capacity using a fixed effects specification and find that FIT policies have driven solar PV development in the EU. However, this effect is overstated without controlling for country characteristics and is concealed without accounting for policy design. We do not find robust evidence that FIT policies have driven wind power development. Overall, we show that the interaction of policy design, electricity price, and electricity production cost is a more important determinant of RES-E development than policy enactment alone. - Highlights: ► This is the first econometric study of feed-in tariff (FIT) efficacy in Europe. ► We test the impact of FIT's on photovoltaic (PV) and wind power from 1992 to 2008. ► We calculate country- and year-specific return on investment provided by each FIT. ► FIT policies increased PV installations by ∼0.5% per ROI percentage point. ► Policy design, market traits, and ROI are more important factors than policy alone.

  17. Governmental intervention approaches to promote renewable energies—Special emphasis on Japanese feed-in tariff

    2012-01-01

    Almost all countries have issued laws and regulations to promote renewable energy (RE). However, the applications and motivations of such laws as well as achievements have been different. Currently, the Japanese government has announced its targets to expand the electricity feed-in tariff scheme for solar power, along with other energy sources, within two years to meet the goal set by the Japanese Prime Minister who, in the 15th United Nations Climate Change Conference (COP15) held in September 2009, proclaimed to cut 25% of greenhouse gas (GHG) emissions from the 1990 levels by 2020. In this paper, the current Japanese energy policies and measures for promoting RE in comparison to popular methods followed worldwide are explored. Furthermore, a Least Cost Feed-in Tariff (LCFIT) Simulation Model for Japanese case was developed to calculate the optimal mix of technologies to reach certain targets. The LCFIT also calculates the tariff that should be proposed for each technology and the total cost for the program with and without a carbon tax and estimates the premium added to the bill of the customer every month. - Highlights: ► RE governmental interventions vary with country's economical, social and topological condition. ► LCFIT Model showed that Japan can apply the FiT system with reasonable burdens on the customers. ► Applying 20% of carbon tax can lead to declining the burdens on the customer by about 32%–45%. ► The R and D expenditures on RE is almost one-fourth that of nuclear power in some countries. ► Japanese scenarios seem very satisfying compared to that of Germany and other European countries.

    In the presence of learning spillovers related to renewable energy technologies, an optimal strategy to mitigate climate change should complement an emissions tax by a subsidy for renewables. This article addresses the question how such subsidy should be designed. It is shown that the widely-used approach of a revenue-neutral fixed feed-in tariff can yield an optimal outcome under restrictive conditions only. It has to be adapted continuously as the electricity price changes. Moreover, funding the tariff by a surcharge on the electricity price has important implications for the design of the emission tax. The optimal tax rate has to be below the Pigovian level, differentiated across fossil fuels and adapted over time as the patterns of technological development change. These requirements may pose a formidable challenge for practical decision-making. However, it is important to point out that the eventual choices made with respect to the design and funding of a feed-in tariff have to be based on a careful and more comprehensive policy assessment, including, inter alia, economic effects beyond the electricity sector and existing institutional constraints. - Highlights: • Learning spillovers may warrant a combination of emissions and technology policies. • A revenue-neutral feed-in tariff can correct learning spillovers efficiently. • Optimal implementation of this approach is tedious in practice though. • Tariff and emissions tax have to be differentiated and adapted continuously. • Eventual policy decision depends on institutional constraints and economy-wide effects

    Many studies show that Tariff Escalation (TE) lowers export shares in many of the processing sectors, given their higher level of protection. However, there are instances when the export shares of processed sectors are higher despite the existence of TE. We examine both these contrasting cases of TE in this paper. On the one hand, there is TE in coffee and coffee products in developing countries, which lead in raw coffee exports and lag in roasted coffee exports. On the other hand, there is a...

    While theories of consciousness differ substantially, the 'conscious access hypothesis', which aligns consciousness with the global accessibility of information across cortical regions, is present in many of the prevailing frameworks. This account holds that consciousness is necessary to integrate information arising from independent functions such as the specialist processing required by different senses. We directly tested this account by evaluating the potential for associative learning between novel pairs of subliminal stimuli presented in different sensory modalities. First, pairs of subliminal stimuli were presented and then their association assessed by examining the ability of the first stimulus to prime classification of the second. In Experiments 1-4 the stimuli were word-pairs consisting of a male name preceding either a creative or uncreative profession. Participants were subliminally exposed to two name-profession pairs where one name was paired with a creative profession and the other an uncreative profession. A supraliminal task followed requiring the timed classification of one of those two professions. The target profession was preceded by either the name with which it had been subliminally paired (concordant) or the alternate name (discordant). Experiment 1 presented stimuli auditorily, Experiment 2 visually, and Experiment 3 presented names auditorily and professions visually. All three experiments revealed the same inverse priming effect with concordant test pairs associated with significantly slower classification judgements. Experiment 4 sought to establish if learning would be more efficient with supraliminal stimuli and found evidence that a different strategy is adopted when stimuli are consciously perceived. Finally, Experiment 5 replicated the unconscious cross-modal association achieved in Experiment 3 utilising non-linguistic stimuli. The results demonstrate the acquisition of novel cross-modal associations between stimuli which are not

  3. The networked minority: How a small group prevailed in a local windfarm conflict

    2013-01-01

    This paper aims to explain through a qualitative case study how a small protest group prevailed during a local windfarm conflict in south-eastern Australia. A social capital analytical framework was developed to analyse the data. The analysis found that two communities inhabited the area for which the windfarm development was proposed. The public participation process failed to address the concerns of both communities and led to the emergence of a social network of resistance. The network had high stocks of bridging social capital, which enabled an effective protest that led to the abandonment of the development. Their effectiveness was inadvertently aided by the windfarm supporters who were unable to act collectively to defend their interests because socio-economic changes in the community among other factors had led to a depletion of their social capital. In this context, different democratic participatory processes were needed to address the concerns of the two communities. Guidance and tools for researching and developing the types of participatory processes needed for vulnerable communities with low social capital and those similar to the social network with high social capital are provided. These will inform community-appropriate public participation processes and participatory planning policy. - Highlights: ► A case study of a local social network's resistance to a windfarm is undertaken. ► The link between high social capital and resistance is confirmed. ► Successful protest groups can be aided by passive windfarm supporters. ► Protesters are likely to participate in well-designed participatory processes. ► Guidance for developing community-specific participatory processes is provided

    This study examines the variability and change in the patterns of climatic extremes experienced in Indus-Delta of Sindh province of Pakistan, comprising regions of Karachi, Badin, Mohenjodaro, and Rohri. The homogenized daily minimum and maximum temperature and precipitation data for a 36-year period were used to calculate 13 and 11 indices of temperature and precipitation extremes with the help of RClimDex, a program written in the statistical software package R. A non-parametric Mann-Kendall test and Sen's slope estimates were used to determine the statistical significance and magnitude of the calculated trend. Temperatures of summer days and tropical nights increased in the region with overall significant warming trends for monthly maximum temperature as well as for warm days and nights reflecting dry conditions in the study area. The warm extremes and nighttime temperature indices showed greater trends than cold extremes and daytime indices depicting an overall warming trends in the Delta. Historic decrease in the acreage of major crops and over 33% decrease in agriculture credit for Sindh are the indicators of adverse impacts of warmer and drier weather on Sindh agriculture. Trends reported for Karachi and Badin are expected to decrease rice cultivation, hatching of fisheries, and mangroves forest surrounding these cities. Increase in the prevailing temperature trends will lead to increasingly hotter and drier summers resulting to constraints on cotton, wheat, and rice yield in Rohri and Mohenjodaro areas due to increased crop water requirements that may be met with additional groundwater pumping; nonetheless, the depleted groundwater resources would have a direct impact on the region's economy.

  5. Projected changes in prevailing winds for transatlantic migratory birds under global warming.

    A number of terrestrial bird species that breed in North America cross the Atlantic Ocean during autumn migration when travelling to their non-breeding grounds in the Caribbean or South America. When conducting oceanic crossings, migratory birds tend to associate with mild or supportive winds, whose speed and direction may change under global warming. The implications of these changes for transoceanic migratory bird populations have not been addressed. We used occurrence information from eBird (1950-2015) to estimate the geographical location of population centres at a daily temporal resolution across the annual cycle for 10 transatlantic migratory bird species. We used this information to estimate the location and timing of autumn migration within the transatlantic flyway. We estimated how prevailing winds are projected to change within the transatlantic flyway during this time using daily wind speed anomalies (1996-2005 and 2091-2100) from 29 Atmosphere-Ocean General Circulation Models implemented under CMIP5. Autumn transatlantic migrants have the potential to encounter strong westerly crosswinds early in their transatlantic journey at intermediate and especially high migration altitudes, strong headwinds at low and intermediate migration altitudes within the Caribbean that increase in strength as the season progresses, and weak tailwinds at intermediate and high migration altitudes east of the Caribbean. The CMIP5 simulations suggest that, during this century, the likelihood of autumn transatlantic migrants encountering strong westerly crosswinds will diminish. As global warming progresses, the need for species to compensate or drift under the influence of strong westerly crosswinds during the initial phase of their autumn transatlantic journey may be diminished. Existing strategies that promote headwind avoidance and tailwind assistance will likely remain valid. Thus, climate change may reduce time and energy requirements and the chance of mortality or

    The spontaneous growth of cloud condensation nuclei (CCN) into cloud droplets under supersaturated water vapour conditions is described by classic Köhler theory. This spontaneous activation of CCN depends on the interplay between the Raoult effect, whereby activation potential increases with decreasing water activity or increasing solute concentration, and the Kelvin effect, whereby activation potential decreases with decreasing droplet size or increases with decreasing surface tension, which is sensitive to surfactants. Surface tension lowering caused by organic surfactants, which diminishes the Kelvin effect, is expected to be negated by a concomitant reduction in the Raoult effect, driven by the displacement of surfactant molecules from the droplet bulk to the droplet-vapour interface. Here we present observational and theoretical evidence illustrating that, in ambient air, surface tension lowering can prevail over the reduction in the Raoult effect, leading to substantial increases in cloud droplet concentrations. We suggest that consideration of liquid-liquid phase separation, leading to complete or partial engulfing of a hygroscopic particle core by a hydrophobic organic-rich phase, can explain the lack of concomitant reduction of the Raoult effect, while maintaining substantial lowering of surface tension, even for partial surface coverage. Apart from the importance of particle size and composition in droplet activation, we show by observation and modelling that incorporation of phase-separation effects into activation thermodynamics can lead to a CCN number concentration that is up to ten times what is predicted by climate models, changing the properties of clouds. An adequate representation of the CCN activation process is essential to the prediction of clouds in climate models, and given the effect of clouds on the Earth’s energy balance, improved prediction of aerosol-cloud-climate interactions is likely to result in improved assessments of future

  8. Prevailing negative soil biota effect and no evidence for local adaptation in a widespread Eurasian grass.

    2011-03-01

    Full Text Available Soil biota effects are increasingly accepted as an important driver of the abundance and distribution of plants. While biogeographical studies on alien invasive plant species have indicated coevolution with soil biota in their native distribution range, it is unknown whether adaptation to soil biota varies among populations within the native distribution range. The question of local adaptation between plants and their soil biota has important implications for conservation of biodiversity and may justify the use of seed material from local provenances in restoration campaigns.We studied soil biota effects in ten populations of the steppe grass Stipa capillata from two distinct regions, Europe and Asia. We tested for local adaptation at two different scales, both within (ca. 10-80 km and between (ca. 3300 km regions, using a reciprocal inoculation experiment in the greenhouse for nine months. Generally, negative soil biota effects were consistent. However, we did not find evidence for local adaptation: both within and between regions, growth of plants in their 'home soil' was not significantly larger relative to that in soil from other, more distant, populations.Our study suggests that negative soil biota effects can prevail in different parts of a plant species' range. Absence of local adaptation points to the possibility of similar rhizosphere biota composition across populations and regions, sufficient gene flow to prevent coevolution, selection in favor of plasticity, or functional redundancy among different soil biota. From the point of view of plant--soil biota interactions, our findings indicate that the current practice of using seeds exclusively from local provenances in ecosystem restoration campaigns may not be justified.

  9. Photon Optimizer (PO) prevails over Progressive Resolution Optimizer (PRO) for VMAT planning with or without knowledge-based solution.

    The enhanced dosimetric performance of knowledge-based volumetric modulated arc therapy (VMAT) planning might be jointly contributed by the patient-specific optimization objectives, as estimated by the RapidPlan model, and by the potentially improved Photon Optimizer (PO) algorithm than the previous Progressive Resolution Optimizer (PRO) engine. As PO is mandatory for RapidPlan estimation but optional for conventional manual planning, appreciating the two optimizers may provide practical guidelines for the algorithm selection because knowledge-based planning may not replace the current method completely in a short run. Using a previously validated dose-volume histogram (DVH) estimation model which can produce clinically acceptable plans automatically for rectal cancer patients without interactive manual adjustment, this study reoptimized 30 historically approved plans (referred as clinical plans that were created manually with PRO) with RapidPlan solution (PO plans). Then the PRO algorithm was utilized to optimize the plans again using the same dose-volume constraints as PO plans, where the line objectives were converted as a series of point objectives automatically (PRO plans). On the basis of comparable target dose coverage, the combined applications of new objectives and PO algorithm have significantly reduced the organs-at-risk (OAR) exposure by 23.49-32.72% than the clinical plans. These discrepancies have been largely preserved after substituting PRO for PO, indicating the dosimetric improvements were mostly attributable to the refined objectives. Therefore, Eclipse users of earlier versions may instantly benefit from adopting the model-generated objectives from other RapidPlan-equipped centers, even with PRO algorithm. However, the additional contribution made by the PO relative to PRO accounted for 1.54-3.74%, suggesting PO should be selected with priority whenever available, with or without RapidPlan solution as a purchasable package.

    Located in Southeast Asia, Indonesia and the Philippines are characterized by a tropical climate and high amounts of rainfall that render their high potential for hydro-power and wind energy deployment. The volcanic geography of both countries also indicates their high geothermal potential compared with that of other countries, and their high solar radiation level makes them suitable areas to establish power plants. The present study is an archival-statistical overview of the potential generation of renewable energy in Indonesia and the Philippines and the implementation of the Feed-in-tariff (FiT) policy. This research focuses on the challenges encountered by politicians and policymakers and confirms the insufficient production of energy from wind, solar, and bio-gas sources despite the potential and the attempts to deploy FiT. Results show that the role of the government in providing support to investors is not clear in both countries. In addition, inflation rates have not been calculated. However, FiT has benefitted both countries by preventing degression during the primary years. - Highlights: • Both countries are unsuccessful in finalizing a fixed Feed-in-tariff payment. • Both have the same aims from FiT but they have different mechanisms. • The Philippines has shown good ability in managing geothermal energy. • Indonesia's energy generation from biomass is better managed than the Philippines. • Both do not have significant energy production from the wind, solar and biogas

    Although financial support for renewable electricity sources has existed via the non-fossil fuel obligation since 1990, the UK 'green power' market is still in its infancy. This paper looks at attitudes to tariffs for 'green power' in light of the proposed phase-out of the non-fossil fuel obligation. The hypothesis tested was the consumer's willingness to pay for electricity generated from renewable energy sources and to see if this was related to income and attitude. Data for analysis were taken from replies to a questionnaire sent to an energy-aware subpopulation of Leicester which were analysed by a variety of statistical tests. Results of multiple regression analysis indicated that whether someone was willing to pay more was significantly correlated with attitude, experience (whether they had visited an environmental centre) and the purchasing power placed on GBP 5.00. This finding has implications for the methods by which support for green tariffs can be increased. Education and raising people's awareness through experience should be able to change attitudes and so increase their willingness to pay. (author)

  15. The effect of the water tariff structures on the water consumption in Mallorcan hotels

    Deyà-Tortella, Bartolomé; Garcia, Celso; Nilsson, William; Tirado, Dolores

    2016-08-01

    Tourism increases water demand, especially in coastal areas and on islands, and can also cause water shortages during the dry season and the degradation of the water supply. The aim of this study is to evaluate the impact of water price structures on hotel water consumption on the island of Mallorca (Spain). All tourist municipalities on the island use different pricing structures, such as flat or block rates, and different tariffs. This exogenous variation is used to evaluate the effect of prices on water consumption for a sample of 134 hotels. The discontinuity of the water tariff structure and the fixed rate, which depends on the number of hotel beds, generate endogeneity problems. We propose an econometric model, an instrumental variable quantile regression for within artificial blocks transformed data, to solve both problems. The coefficients corresponding to the price variables are not found to be significantly different from zero. The sign of the effect is negative, but the magnitude is negligible: a 1% increase in all prices would reduce consumption by an average of only 0.024%. This result is probably due to the small share of water costs with respect to the total hotel operational costs (around 4%). Our regression model concludes that the introduction of water-saving initiatives constitutes an effective way to reduce consumption.

    Directory of Open Access Journals (Sweden)

    Y. I. Portnyagin

    2004-11-01

    Full Text Available The Arctic MLT wind regime parameters measured at the ground-based network of MF and meteor radar stations (Andenes 69° N, Tromsø 70° N, Esrange 68° N, Dixon 73.5° N, Poker Flat 65° N and Resolute Bay 75° N are discussed and compared with those observed in the mid-latitudes. The network of the ground-based MF and meteor radars for measuring winds in the Arctic upper mesosphere and lower thermosphere provides an excellent opportunity for study of the main global dynamical structures in this height region and their dependence from longitude. Preliminary estimates of the differences between the measured winds and tides from the different radar types, situated 125-273km apart (Tromsø, Andenes and Esrange, are provided. Despite some differences arising from using different types of radars it is possible to study the dynamical wind structures. It is revealed that most of the observed dynamical structures are persistent from year to year, thus permitting the analysis of the Arctic MLT dynamics in a climatological sense. The seasonal behaviour of the zonally averaged wind parameters is, to some extent, similar to that observed at the moderate latitudes. However, the strength of the winds (except the prevailing meridional wind and the diurnal tide amplitudes in the Arctic MLT region is, in general, less than that detected at the moderate latitudes, decreasing toward the pole. There are also some features in the vertical structure and seasonal variations of the Arctic MLT winds which are different from the expectations of the well-known empirical wind models CIRA-86 and HWM-93. The tidal phases show a very definite longitudinal dependence that permits the determination of the corresponding zonal wave numbers. It is shown that the migrating tides play an important role in the dynamics of the Arctic MLT region. However, there are clear indications with the presence in some months of non-migrating tidal modes of significant appreciable amplitude.

    Full Text Available Largely depending on the meltwater from the Hindukush–Karakoram–Himalaya, withdrawals from the upper Indus Basin (UIB contribute half of the surface water availability in Pakistan, indispensable for agricultural production systems, industrial and domestic use, and hydropower generation. Despite such importance, a comprehensive assessment of prevailing state of relevant climatic variables determining the water availability is largely missing. Against this background, this study assesses the trends in maximum, minimum and mean temperatures, diurnal temperature range and precipitation from 18 stations (1250–4500 m a.s.l. for their overlapping period of record (1995–2012 and, separately, from six stations of their long-term record (1961–2012. For this, a Mann–Kendall test on serially independent time series is applied to detect the existence of a trend, while its true slope is estimated using the Sen's slope method. Further, locally identified climatic trends are statistically assessed for their spatial-scale significance within 10 identified subregions of the UIB, and the spatially (field- significant climatic trends are then qualitatively compared with the trends in discharge out of corresponding subregions. Over the recent period (1995–2012, we find warming and drying of spring (field-significant in March and increasing early melt season discharge from most of the subregions, likely due to a rapid snowmelt. In stark contrast, most of the subregions feature a field-significant cooling within the monsoon period (particularly in July and September, which coincides well with the main glacier melt season. Hence, a decreasing or weakly increasing discharge is observed from the corresponding subregions during mid- to late melt season (particularly in July. Such tendencies, being largely consistent with the long-term trends (1961–2012, most likely indicate dominance of the nival but suppression of the glacial melt regime

    The question of the electricity's price policy, referred as social tariff, is usually analyzed in terms of the economic sustainability of its application by the concessionaires of public utilities, responsible for its implementation, vis a vis the biggest possible benefit in social terms. To satisfy both of these conditions, it is necessary to definite the criteria that allows to clearly identify the target population who will receive the benefit. This paper analyzes the use of the criterion of 'housing standard' as a criterion for the implementation of the Social Tariff, contributing for the debate on the definition of the social benefits policy for the low-income consumers of electrical energy, currently under revision.

    In adherence to the EU Directive on the ``Transparency of Gas and Electricity Tariffs Paid by the Industrial End Consumer`` the Statistical Office of the European Union (eurostat) since July 1991 has biannually pusblished the gas and electricity tariffs paid by industrial consumers. In order to approximate the consumers` real situation as closely as possible these surveys determine the effective tariffs for typical consumption rates in certain towns or service areas of a country rather than just giving mean values. Selection of towns depends on several criteria such as, for example, population, economic import, different tariff zones, or the intent to give a representative picture of a country`s geography. In the present study, one town was chosen from every country to permit an international comparison. (orig./UA) [Deutsch] Gemaess der EU-Richtlinie bezueglich der ``Transparenz der vom industriellen Endverbraucher zu zahlenden Gas- und Strompreise`` veroeffentlicht das Statistische Amt der Europaeischen Union (eurostat) seit Juli 1991 halbjaehrlich die vom industriellen Verbraucher zu zahlenden Strom- und Erdgaspreise. Um der tatsaechlichen Lage der Verbraucher moeglichst nahe zu kommen, werden anstatt von Durchschnittswerten die Preise bei typischen Abnahmeverhaeltnissen fuer bestimmte Staedte oder Versorgungsgebiete eines Landes erhoben. Fuer die Auswahl der Staedte sind dabei mehrere Kriterien massgebend, wie z.B. Bevoelkerungszahl, wirtschaftliche Bedeutung, unterschiedliche Tarifzonen oder auch die geografisch ausgewogene Erfassung eines Staates. Fuer den internationalen Vergleich wurde stellvertretend fuer jedes Land, jeweils eine Stadt ausgewaehlt. (orig./UA)

  15. The stuttering energy transition in Germany: Wind energy policy and feed-in tariff lock-in

    International Nuclear Information System (INIS)

    Nordensvärd, Johan; Urban, Frauke

    2015-01-01

    This article aims to examine whether the formulation of specific low carbon policy such as the feed-in tariff for wind energy in Germany can partly be a barrier to a comprehensive energy transition (Energiewende). Despite their short and medium-term success, these policies could create a long-term lock-in if they are formulated in a way that leads to a stagnation of systems innovation. The research finds that while the share of wind energy has increased rapidly over time, the feed-in-tariff and other low carbon policies and incentives have not been sufficient to achieve a socio-technical regime transition in Germany yet. We suggest that the German feed-in-tariff has incorporated wind energy (a niche-innovation) and wind energy actors (pathway newcomers) into a slightly modified socio-technical regime that is rather similar to the earlier ‘fossil fuel dominant’ socio-technical regime. -- Highlights: •Feed-in tariff favours specific wind innovation, rather than energy transition. •Wind energy incorporated into a slightly modified socio-technical regime. •The outdated grid infrastructure is a bottleneck for the wind energy sector

  20. Tailored emails prompt electric vehicle owners to engage with tariff switching information

    The carbon intensity of the electricity used to charge an electric vehicle (EV) is dependent on when in the day charging occurs. However, persuading EV owners to adopt incentives to charge during off-peak hours is challenging. Here we show that governments could exploit the 'window of opportunity' created when people purchase their first EV to promote time-of-use tariffs. Email recipients (n = 7,038 EV owners) were more likely to click-through to an information webpage when the email emphasized specific reductions in home-charging costs versus general bill savings. However, the 'window of opportunity' for maximizing potential adoption is short; email open rates declined from over 70% immediately after purchase to 40% for recipients owning their EV for over three months. These results demonstrate the potential of prompts to change behaviours for which opt-out enrolment (where enrolment is automatic unless people explicitly opt out) would be unethical or less effective.

    Full Text Available The sole implementation of a Bus Rapid Transit System -BRT parallel to the conventional is not enough to guarantee meeting users and operators’ needs within the Metropolitan Area of Bucaramanga -MAB, Colombia. As time passed, these systems became inefficient; as a result, users started looking for alternative non-formal transportation means and the State incurred in additional financing for the permanence of the system. This paper seeks to bolster the modes of public transportation through a fare strategy that agrees with the actual distances travelled by the user. In other words, the purpose of this work is to establish tariff zones for the AMB to differentiate between those users moving in short journeys and those who travel long distances to get to their destination in order to create a balance between the users’ benefit, the quality of the travel, and the operation costs of BRT.

  3. Promotion of renewable energy resources with a focus on cost-based feed-in tariffs

    2006-01-01

    This final report published by the Swiss Federal Office of Energy (SFOE) presents a review of possible systems that could be used to promote power production in Switzerland using renewable energy sources. Promotional models on both the provider and consumer sides that use both price and quantity as control factors are examined. Three models are compared: the submission-to-tender model, the quota model with certificates and a model that uses cost-based feed-in tariffs. On the basis of a comparison with Austria, interaction between increasing the proportion of renewable forms of energy and the realisation of energy-efficiency goals is discussed. A further part of the report deals with various options for the use of biomass as a source of energy

  4. Electricity tariffs in India: an assessment of consumers' ability and willingness to pay in Gujarat

    Ranjan Kumar Bose; Megha Shukla

    2001-01-01

    A sample of electricity consumers covering agricultural, residential and industrial consumers, in the Indian State of Gujarat was surveyed in 1997 to investigate the consumers' ability and willingness to pay for electricity supplied from the grid. The ability to pay was estimated using the weight of the cost of electricity to meet at least the basic household needs in relation to the overall income or expenditure. The willingness to pay was estimated using the costs of meeting the needs by alternative sources of energy, namely diesel in the case of farmers to pump water for irrigation and captive power generation using diesel generators in the case of industrial users. Survey results reveal the proportion of consumers in different categories, which do not have the ability to pay more or are even not willing to pay more for electricity. The survey findings have been used as a guideline in the proposed adjustment of tariffs charged by the Gujarat Electricity Board. (author)

    Power supply companies in German-speaking countries expect a marked shortening of product life cycles over the next five years. This means that new products will need to be developed at ever shorter time intervals. However, opinions on the success of newly introduced products are mediocre. While there is an understanding that the product portfolio should meet customers' needs, the importance of the conceptualisation phase in developing suitable products is systematically underestimated. A study performed by a reputed strategic consultancy firm has shown that at least when it comes to tariff migration there is a failure to address customers in a differentiated manner. A rethink in conceptualising product portfolios is needed if the success of new product launches is to be driven by other criteria than merely the price.

    Energy Technology Data Exchange (ETDEWEB)

    Fink, S.; Porter, K.; Rogers, J.

    2010-10-01

    Feed-in tariffs (FITs) have been used to promote renewable electricity development in over 40 countries throughout the past two decades. These policies generally provide guaranteed prices for the full system output from eligible generators for a fixed time period (typically 15-20 years). Due in part to the success of FIT policies in Europe, some jurisdictions in the United States are considering implementing similar policies, and a few have already put such policies in place. This report is intended to offer some guidance to policymakers and regulators on how generator interconnection procedures may affect the implementation of FITs and how state generator interconnection procedures can be formulated to support state renewable energy objectives. This report is based on a literature review of model interconnection procedures formulated by several organizations, as well as other documents that have reviewed, commented on, and in some cases, ranked state interconnection procedures.

  10. Engel curves, household characteristics and low-user tariff schemes in natural gas

    International Nuclear Information System (INIS)

    Navajas, Fernando H.

    2009-01-01

    We explore the relative importance of income and household characteristics (such as family size) in explaining differences in household consumption of natural gas and LPG. In a simple model of vertically (willingness to pay) ordered households we posit that the relative importance of the income elasticity of demand (vs. the family size elasticity) depends positively on the price faced by households. Thus, very low prices tend to depress the across households income elasticity of demand relative to the characteristic-elasticity and the opposite holds for under high prices. We test this hypothesis using, for the first time in Argentina, data from the household expenditure survey on Natural gas and LPG and compare the cross-consumption equations for both fuels, which have quite different price regimes. Finally, we explore welfare implications for low-user tariff scheme reforms in natural gas. (author)

    Existing energy policy frameworks revolving around the acceleration of deployment of renewable energy technology can be broadly classified as the quantity vs. price approach. With this brief viewpoint, this paper suggests another perspective of viewing these instruments in terms of a more fundamental basis: whether the deployment in capacity is in terms of a cost minimization approach or a network externality approach. We suggest that the generic price or feed in tariff (FIT) approach in subsidizing renewable electricity generation and associated income would create a bandwagon or self-propagation effect among users rendering the renewable energy technology spreads like a software or information technology. Our objective is to raise awareness of this technology dynamics oriented perspective in renewable deployment supplementing the conventional installation subsidies perspective. We hope that it would inspire more empirical works and studies relating to the policy implications of this viewpoint.

    In a number of countries, reimbursement to hospitals providing renal dialysis services is set according to a fixed tariff. While the cost of maintenance dialysis and transplant surgery are amenable to a system of fixed tariffs, patients with established renal failure commonly present with comorbid conditions that can lead to variations in the need for hospitalization beyond the provision of renal replacement therapy. Patient-level cost data for incident renal replacement therapy patients in England were obtained as a result of linkage of the Hospital Episodes Statistics dataset to UK Renal Registry data. Regression models were developed to explore variations in hospital costs in relation to treatment modality, number of years on treatment and factors such as age and comorbidities. The final models were then used to predict annual costs for patients with different sets of characteristics. Excluding the cost of renal replacement therapy itself, inpatient costs generally decreased with number of years on treatment for haemodialysis and transplant patients, whereas costs for patients receiving peritoneal dialysis remained constant. Diabetes was associated with higher mean annual costs for all patients irrespective of treatment modality and hospital setting. Age did not have a consistent effect on costs. Combining predicted hospital costs with the fixed costs of renal replacement therapy showed that the total cost differential for a patient continuing on dialysis rather than receiving a transplant is considerable following the first year of renal replacement therapy, thus reinforcing the longer-term economic advantage of transplantation over dialysis for the health service. © The Author 2015.

  16. Combining tariffs, investment subsidies and soft loans in a renewable electricity deployment policy

    Mir-Artigues, Pere; Río, Pablo del

    2014-01-01

    Policy combinations and interactions have received a considerable attention in the climate and energy policy realm. However, virtually no attention has been paid to the analysis of the combination of different deployment instruments for the same renewable energy technology. This neglect is all the more striking given the existence in current policy practice of combinations of deployment instruments either across technologies or for the same technology, both in the EU and elsewhere. What renewable electricity support policies to use and, therefore, how to combine them in order to promote the deployment of renewable energy technologies cost-effectively is a main concern of governments. The aim of this paper is to provide insight on the cost-effectiveness of combinations of deployment instruments for the same technology. A financial model is developed for this purpose, whereby feed-in tariffs (FITs) are combined with investment subsidies and soft loans. The results show that the policy costs of combinations are the same as for the FITs-only option. Therefore, combining deployment instruments is not a cost-containment strategy. However, combinations may lead to different inter-temporal distributions of the same amount of policy costs and, thus, differently affect the social acceptability and political feasibility of renewable energy support. - Highlights: • Insight on the cost-effectiveness of combinations of deployment instruments for the same technology. • A financial model is developed. • Feed-in tariffs (FITs) are combined with investment subsidies and soft loans. • The policy costs of combinations are the same as for the FITs-only option. • Therefore, combining deployment measures is not a cost-containment strategy

    Malaysia enacted the Renewable Energy Act in April 2011. One of its important components is the feed-in tariff (FiT) scheme—launched in December 2011. The scheme is managed and administered by the Sustainable Energy Development Authority (SEDA) of Malaysia. This paper analyses the impact of the FiT mechanism in Malaysia a year after its implementation; particularly on the installation and economical aspects. First, the history of the scheme is presented before summarising the application process for the scheme. Next, a detailed evaluation on the implication of the scheme is discussed. Some of the key findings from the analysis include: (i) the uptake for renewable energy installations has been extremely high, particularly for solar photovoltaic installation; (ii) the foreign and domestic direct investment related to renewable sectors have increased significantly; (iii) more ‘green’ jobs have been created, particularly in the manufacturing and installation sectors, and (iv) there are plans to include wind and thermal energy in the FiT scheme. It can be concluded that the FiT scheme in Malaysia has produced significant impact during the first year of its implementation. With a proper monitoring by SEDA and more awareness among the people, renewable energy will most likely flourish in Malaysia. - Highlights: • Malaysia launched the feed-in tariff (FiT) scheme in December 2011. • The one year progress is evaluated in terms of installation and economical aspects. • The uptake for renewable energy installations has been extremely high. • Investment related to renewable sectors has increased significantly. • More ‘green’ jobs have been created in the country

    The new tariffs for the use of regulated LNG terminals in Montoir-de-Bretagne (Montoir) and Fos Tonkin, which are operated by Elengy, and for the Fos Cavaou terminal, which is operated by Fosmax LNG, known as 'ATTM51', take effect on 1 April 2017 for a period of approximately four years. They were adopted after a broad consultation of stakeholders and following studies that were made public. The ATTM5 tariffs offer all stakeholders visibility on the changes to tariffs between 2017 and 2021, and provide incentive to LNG terminal operators to improve their efficiency in terms of both cost control and the service quality provided to the users of their terminals. The ATTM5 tariffs show a significant reduction compared to the ATTM4 tariffs: the decrease of the average unit tariff for the ATTM5 period is of 6.5 % for Montoir, 18.2 % for Fos Tonkin, and 18.6 % for Fos Cavaou. These decreases are mainly due to the lower return on assets. To a lesser extent, the reduced operating expenses reinforce the tariff reduction. They can be partly explained by the reduced expenditure related to the decrease in activity, and by the higher productivity achieved by Elengy and Fosmax LNG over the ATTM4 period, enabling the LNG terminal users to benefit from this. The ATTM5 tariffs introduce a change to the structure of the services offer. They create in particular a basic service, the main offer of the LNG terminal operators, which can be supplemented by the subscription to a uniform option. They extend several experimental services initiated during the ATTM4 tariff period. They increase the flexibility available to the terminal's clients on their subscriptions. Finally, they give Fosmax LNG the possibility to offer over the long-term the 10 % capacity previously restricted to the short-term subscriptions

    Economists and policy makers frequently propose real time pricing (RTP) as a strategy for facilitating price responsive demand, thereby improving the performance of electricity markets and regional networks. While theoretically appealing, many practical and empirical issues related to RTP remain unresolved or poorly understood. Over the past two decades, more than 70 utilities in the U.S. have offered voluntary RTP tariffs, on either a pilot or permanent basis. However, most have operated in relative obscurity, and little information has made its way into the public domain. To address this gap, we conducted a conducted a comprehensive review of voluntary RTP programs in the U.S. by surveying 43 U.S. utilities and reviewing regulatory documents, tariffs, program evaluations, and other publicly available sources. Based on this review of RTP program experience, we identify key trends related to utilities' motivations and goals for implementing RTP, evolution of RTP tariff design, program participation, participant price response, and program outlook. Experience with voluntary RTP programs has been mixed. Several utilities have demonstrated that voluntary RTP programs are capable of generating significant load reductions. However, most programs have attracted relatively few participants and therefore have generated quite limited load reductions. About 2700 non-residential customers were enrolled in RTP programs in 2003, representing more than 11 000 MW of load. We then draw from these findings to identify implications for policy makers and regulators that are currently considering RTP as a strategy for facilitating price responsive demand

    First included into the energy regulations of the USA in 1978, a feed-in tariff (FiT) is a policy mechanism designed to encourage the adoption of renewable energy sources and to help accelerate the move toward grid parity .FiTs typically include three key provisions including guaranteed grid access, long-term contracts for the electricity produced and purchase prices that are methodologically based on the cost of renewable energy generation and tend towards grid parity. Among other renewable energy subsidies, such as income tax deductions, property tax exemptions, tax credits, loans or loan guaranties, investment credit subsidies and depreciation allowances, well-adapted feed-in tariff regimes are generally considered as the most efficient and effective support schemes for promoting renewable electricity. Up to now, close to seventy countries including developed and developing ones have adapted FiT policies and more are expected to come in the near future. Turkey adapted her initial FiT law in 2005 covering wind, hydro and geothermal sectors. In that law, solar electric power was intentionally excluded claiming the rapid development of the technology and potential cost reductions and a future update in the law covering the missing technologies was foreseen in five years. Adoption of the recent amendment at the end of year 2010 took a sluggish parliamentary process of one and a half years and eventually solar (PV and CSP); biogas-bio-mass power technologies were included in the FiT system along with some improvements on the wind, geothermal and hydro-electric sectors. The recent amendment assumed solar power as dominantly photovoltaic in nature and the base tariff of 0.133 USD/kW-h was determined based on the lowest investment options available on the global photovoltaic market. To promote domestic technology and manufacture, additional bonuses are defined for the domestic content of modules, cells, inverters and controllers and mechanical infrastructure. To enable

The initial six targets included: 1 admission under consultant-led joint orthopedic–geriatric care, 2 multidisciplinary assessment protocol on admission, 3 surgery within 36 hours, 4 geriatrician review within 72 hours, 5 multiprofessional rehabilitation, and 6 assessment for falls and bone protection. We aimed to examine the relationship between BPT achievement and important patient outcomes and whether the BPT could predict these independently of other validated predictors.Materials and methods: A retrospective review was conducted on 516 patient episodes. Four outcomes were defined: 1 30-day mortality, 2 365-day mortality, 3 postoperative length of stay on trauma ward (LOS-T, and 4 total post-operative hospital LOS (LOS-H. Patient episodes were grouped as follows: 1 group 1, pre-BPT, 2 group 2, BPT achievers, 3 group 3, BPT fails. These were compared for mortality (χ2 test and for LOS (Kruskal–Wallis test. Event analysis was done for groups 2 and 3 using generalized linear modeling, with age, sex, American Society of Anesthesiologists grade, hemoglobin, albumin, creatinine, and BPT achievement evaluated as predictors.Results: The three groups did not differ significantly in baseline characteristics or outcomes. In the event analysis, the risk of 30-day mortality was related only to abnormal creatinine (P=0.025; mortality at 365 days was related significantly to low albumin (P=0.023 and weakly to abnormal creatinine (P=0.089.

    Highlights: • A novel, hybrid input–output analysis of historic feed-in tariff impacts. • We explore operational, investment, and opportunity cost/benefits in Portugal. • Environmental (GHG), economic (GDP), and social (job years) impacts are estimated. • For 2000–2010 we find impacts of −7.2 MtCO 2 eq GHG, +1557 M€ GDP and +160,000 job years. • Lifetime impacts are dependent on opportunity costs of future FIT payments. - Abstract: Over the past two decades, many countries have used aggressive policies such as feed-in tariffs and power purchase agreements to promote renewable energy. These policies have been very successful in several countries, initiating large changes in the structure of energy sectors, and conferring large environmental, economic, and social impacts. In this paper, we quantify these impacts over the period 2000–2010 for Portugal; a country that witnessed a substantial increase in renewable energy penetration rates, with the share of wind power in electricity production jumping from 0.4% in 2000 to 16.8% in 2010. We use a novel, hybrid energy-economic input–output model to compare the historical energy policy against a counterfactual scenario in which the surge in energy subsidies and concurrent expansion of renewable energies did not take place. We consider the impact of renewable energy policy stemming from three propagation modes – operational, investment, and opportunity costs – in both the energy sector and the rest of the economy. This is the first time such a comprehensive analysis has been undertaken. Our findings show that, in the period under consideration, the combined historical renewable energy policy and renewable energy developments yielded a clear reduction in emissions, in excess of 7.2 MtCO 2 eq, an increase in GDP of 1557 M€, and a creation of 160 thousand job-years. These estimates do not include opportunity costs from future FIT payments that projects built in this period may be entitled to

    The Galapagos islands in Ecuador are Natural Park since 1959. Four of these are inhabited and about 5 million litres of diesel per year are shipped 1000km from the mainland to generate electricity. This could be representative of other parts of the world. Floreana, the smallest inhabited island has 173km2 and about 200 inhabitants; a diesel genset microgrid was operating in the only village of the island (Puerto Velasco Ibarra), 13h per day. The operating scheme for the electric service is representative of a situation where the users pay a standard grid tariff, and the electric utility (EEPG) is sustained through a cross-subsidy of 25.000 US$ per year. Some users in the island are far from the grid and not connected. Small businesses have to operate their own gensets to complement the existing schedule. With funding mainly from the Parque Nacional Galapagos of Ecuador and support to the European NGO SEBA from AECI and the EC, a project for the implementation of Sustainable infrastructures in Floreana has been executed with the objective to reduce substantially the operational deficit, to offer electricity service to ALL potential users 24 hours a day and to reduce substantially the dangerous fuel transports. So, in the late 2003 a MSG (Multi User Hybrid Grid) was commissioned in Puerto Velasco Ibarra which gives electricity service to 54 users by an 18 kWp PV generator backed by the existing diesel gensets. The scattered houses are supplied with individual stand-alone PV systems with a total of 5,9 kWp. This new service approach with PV hybrid technology is supposed to create yearly savings of nearly 20.000 US$ based on a life-cycle analysis compared with the previous generation scheme by genset. The most important aspects of project implementation are that all users are contractually linked to the energy operator in a unified tariff scheme with segmented flat rated monthly fees (whether connected to the MSG or supplied by individual systems), standard grid

    2017-01-01

    To mitigate anthropogenic climate change, both the heating and transport sectors will need to be electrically driven, with the higher electrical demand met by emission-free technologies, in addition to general efficiency improvements. On the generation side, wind and photovoltaic power plants must have a rated power significantly exceeding the current peak demand, in order to cover this increased electrical requirement. On the consumption side, heat pumps and private electric vehicles will increase the percentage of energy withdrawn at the low-voltage level of the new system. Given the right incentives, these customers will shift the energy demand in such a way as to benefit the system. This flexibility can be used as a tool to deal with variable renewable insertion while avoiding simultaneous overloading of the power grid. This thesis analyses and evaluates the effects of different electricity tariff designs on energy consumption. These tariffs should incentivise households to adapt their energy consumption to market prices, without inducing critical peak demands in times of particularly low prices. Therefore, time-varying energy price components and power price components are combined into flexible electricity tariffs and implemented as target functions within an optimization problem. The cost-minimizing effect of household energy management is determined under these flexible tariffs, and the effects of the tariff designs on energy consumption and the induced costs are evaluated. Additionally, the results of the flexible tariff approach are compared with results from a centralized optimization by a virtual power plant. It is possible to develop a design for a suitable flexible tariff that decreases the energy procurement costs of electric vehicles while simultaneously reducing peak demand in comparison to a single real-time pricing incentive. Furthermore, this thesis shows that certain kinds of electricity tariff design do not only fail to support but actually

    The combination of distributed energy resources (DER) and retail tariff structures to provide benefits to both utility consumers and the utilities is not well understood. To improve understanding, an Integrated Energy System Model (IESM) is being developed to simulate the physical and economic aspects of DER technologies, the buildings where they reside, and feeders servicing them. The IESM was used to simulate 20 houses with home energy management systems on a single feeder under a time-of-use (TOU) tariff to estimate economic and physical impacts on both the households and the distribution utilities. Home energy management systems (HEMS) reduce consumers’ electric bills by precooling houses in the hours before peak electricity pricing. Utilization of HEMS reduce peak loads during high price hours but shifts it to hours with off-peak and shoulder prices, resulting in a higher peak load. used to simulate 20 houses with home energy management systems on a single feeder under a time-of-use (TOU) tariff to estimate economic and physical impacts on both the households and the distribution utilities.

    Renewable energy is becoming a priority for Latin America and Caribbean (LAC) countries because of energy challenges such as demand growth, high dependence on imported fossil fuels, and climate change. As of 2010, 12 LAC countries have implemented formal targets for renewable energy deployment. Some of the LAC countries, namely Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. FITs are long-term, guaranteed purchase agreements for green electricity at a price that can provide project developers a reasonable return on investment. FITs are increasingly popular because if designed well, they can mitigate investor risk in renewables. This article presents a low-risk FIT design and then uses this design to benchmark the existing LAC region FITs. - Highlights: ► 12 LAC countries have implemented formal targets for renewable energy deployment. ► Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. ► Low-risk FIT design of feed-in tariffs in the LAC region can be improved

    District heating plays an important role in the Swedish heat-market. At the same time, the price of district heating varies considerably among different district-heating utilities. A case study is performed here in which a Swedish utility is analysed using three different methods for calculating the marginal costs of heat supply: a manual spreadsheet method, an optimising linear-programming model, and a least-cost dispatch simulation model. Calculated marginal-costs, obtained with the three methods, turn out to be similar. The calculated marginal-costs are also compared to the actual heat tariff in use by the utility. Using prices based on marginal costs should be able to bring about an efficient resource-allocation. It is found that the fixed rate the utility uses today should be replaced by a time-of-use rate, which would give a more accurate signal for customers to change their heat consumptions. (Author)

    Full Text Available Over the last 15 years, the global trade of virgin olive oil (VOO seems to face a stringent regulatory regime, mainly through the imposition of TBT and SPS measures. Such a development should have adversely impacted global levels of VOO trade. However, evidence shows that the world's imports of VOO have more than quadrupled in value since 2000. Alongside this trend, the share of VOO imports gradually shifts from traditional sources (mainly EU to New World producing countries, such as Argentina, Australia, the USA, and Chile. By extracting data from hundreds of NTM regulations, as well as all possible registered bilateral trade flows between 2002 to 2014, this paper aims to empirically explore to what extent particular NTMs impact imports of VOO. The results indicate that while tariffs remain a stringent barrier, most NTMs have a positive impact on imports, rather than enhancing restrictiveness. The paper asserts that the majority of NTMs respond to consumers' demand for higher food safety standards and protection of human health, while increasing available information and transparency. That, in turn, leads to an expansion in the magnitude of imports of VOO products

    Feed-in Tariff (FiT) has been one of the most effective policies in accelerating the development of renewable energy (RE) projects. The amount of RE electricity in the FiT purchase agreement is an important decision that has to be made by the RE project developers. They have to consider various crucial factors associated with RE system operation as well as its stochastic nature. The presented work aims to assess the sensitivity and profitability of a hybrid power system (HPS) in cases of RE system failure or shutdown. The amount of RE electricity for the FiT purchase agreement in various scenarios was determined using a novel tool called On-Grid Problem Table based on the Power Pinch Analysis (PoPA). A sensitivity table has also been introduced to assist planners to evaluate the effects of the RE system's failure on the profitability of the HPS. This table offers insights on the variance of the RE electricity. The sensitivity analysis of various possible scenarios shows that the RE projects can still provide financial benefits via the FiT, despite the losses incurred from the penalty levied. - Highlights: • A Power Pinch Analysis (PoPA) tool to assess the economics of an HPS with FiT. • The new On-Grid Problem Table for targeting the available RE electricity for FiT sale. • A sensitivity table showing the effect of RE electricity changes on the HPS profitability.

    Feed-in tariffs (FITs) are the most widely used renewable energy policy in the world for driving accelerating renewable energy (RE) deployment, accounting for a greater share of RE development than either tax incentives or renewable portfolio standard (RPS) policies. FITs have generated significant RE deployment, helping bring the countries that have implemented them successfully to the forefront of the global RE industry. In the European Union (EU), FIT policies have led to the deployment of more than 15,000 MW of solar photovoltaic (PV) power and more than 55,000 MW of wind power between 2000 and the end of 2009. In total, FITs are responsible for approximately 75% of global PV and 45% of global wind deployment. Countries such as Germany, in particular, have demonstrated that FITs can be used as a powerful policy tool to drive RE deployment and help meet combined energy security and emissions reductions objectives. This policymaker’s guide provides a detailed analysis of FIT policy design and implementation and identifies a set of best practices that have been effective at quickly stimulating the deployment of large amounts of RE generation.

    2017-01-01

    This paper considers the issue of how energy justice is economized; how political and ethical claims about particular energy (in)justices are turned into economic valuations. Drawing on science and technology studies, we present a conceptual framework that understands economization as emerging from three interrelated processes: problematization, framing and overflowing. Applying this framework to the drafting of new energy legislation in Chile, we trace how perceived shortcomings in equity and distributional justice were turned into “market failures,” able to be resolved by market-based mechanisms. This case highlights the dangers implicit in the uncritical economization of energy justice claims, in which ethical considerations regarding the distribution of risks and benefits of energy production and provision are reduced to a redistribution of payments among consumers – something that limits the possibilities for structural reform. - Highlights: • The implementation of an electricity equity tariff is discussed. • A process of economization transforms equity demands into market devices. • Energy justice, as mobilized in the policy process, includes multiple forms of justice. • Competition between these multiple forms fails to deliver a complete form of justice.

    Full Text Available Feed-in-Tariff (FiT mechanisms have been important in boosting renewable energy, by providing a long-term guaranteed subsidy of the kWh-price, thus mitigating investment risks and enhancing the contribution of sustainable electricity. By ongoing PV development, the contribution of solar power increases exponentially. Within this significant potential, it is important for investors, operators, and scientists alike to provide answers to different questions related to subsidies, PV efficiencies and costs. The present paper therefore (i briefly reviews the mechanisms, advantages, and evolution of FiT; (ii describes the developments of PV, (iii applies a comprehensive literature-based model for the solar irradiation to predict the PV solar energy potential in some target European countries, whilst comparing output predictions with the monthly measured electricity generation of a 57 m² photovoltaic system (Belgium; and finally (iv predicts the levelized cost of energy (LCOE in terms of investment and efficiency, providing LCOE values between 0.149 and 0.313 €/kWh, as function of the overall process efficiency and cost. The findings clearly demonstrate the potential of PV energy in Europe, where FiT can be considerably reduced or even be eliminated in the near future.

  1. Feed-in tariff and market electricity price comparison. The case of cogeneration units in Croatia

    International Nuclear Information System (INIS)

    Uran, Vedran; Krajcar, Slavko

    2009-01-01

    In August 2007, the Government of the Republic of Croatia instituted a feed-in tariff system, requiring the Croatian Electricity Market Operator (HROTE) to off-take the electricity produced from renewable energy sources or cogeneration units fueled by natural gas. Analysis of the off-take electricity price range, which depends on the net electrical output and electricity market trends, indicates that it is more cost effective for cogeneration units greater than 1 MW to sell their electricity on the exchange market. This was confirmed by developing a mathematical model to calculate the cost-effectiveness ratio of a cogeneration unit. This ratio represents the relation between the profit spread, i.e. the difference between the profit generated from selling the electricity on the exchange market and the profit made from dispatching the electricity to HROTE, as well as the total investment costs. The model can be applied for changes in certain parameters, such as the net electrical output, volatility and spot electricity price. The Monte Carlo method is used to obtain the most probable cost-effectiveness ratio and average future electricity price. Together with these two economic parameters and market price analysis, it is possible to calculate and calibrate an acceptable off-take electricity price. (author)

    In this paper we analyse the impact of the regulatory framework for the new regulatory period (2011-2013) on the long-term profitability of TenneT TSO, the operator of the high-voltage electricity network in the Netherlands. Long-term profitability is a key component of the financeability of a firm. In the long run, the return on capital should be at least equal to the opportunity costs of capital in order to finance investments. As the ultimate indicator for the long-term profitability, we use the net present value of economic profit, which is the difference between total revenues and total costs, including a normal return on capital. In order to simulate the future financial development of the TSO, we developed a model. On the basis of the model analysis, making a number of methodological assumptions, we conclude that the tariff regulation results in a positive long-term profitability, implying that the regulatory framework enables TenneT TSO to finance its investments in replacement and network expansion. In the long run all costs, including the normal costs of capital, will be fully compensated by the revenues, resulting in a (slightly) positive net present value of economic profit. This conclusion is subject to the condition that the TSO eliminates the existing inefficiencies in the network and that it is able to annually improve its overall efficiency. If this condition is not met, the shareholder might face a loss of more than one hundred million Euros.

    Brazil has gone through its worst crisis in electricity supply in the past fifty years. The justifications for the current crisis are found in the eighties, when there was a long period of under investment in the sector, until then controlled and managed exclusively by the state, especially in the expansion of generation and power transmission network. The lack of financial resources by the state led to the delay or suspension of expansion projects. Consumption, meanwhile, increased when the economy grew and continued to increase even when the economy stagnated, as more people gained access to electricity. It became imperative, then implode the model that barely functioned at that time under the command of the state and devise a new model for the electricity sector, which should have as main goals: to attract the participation of private investment coupled with gradual tariff reduction the State, in addition to increased competition among agents in the chain, to enable the pricing more affordable to society, and better quality services.

    Through July 2017, corporate customers contracted for more than 2,300 MW of utility-scale solar. This paper examines the benefits, challenges, and outlooks for large-scale off-site solar purchasing through four pathways: PPAs, retail choice, utility partnerships (green tariffs and bilateral contracts with utilities), and by becoming a licensed wholesale seller of electricity. Each pathway differs based on where in the United States it is available, the value provided to a corporate off-taker, and the ease of implementation. The paper concludes with a discussion of future pathway comparison, noting that to deploy more corporate off-site solar, new procurement pathways are needed.

    Historical occurrence of methane in residential water wells in parts of the Appalachian basin (Pennsylvania, New York, West Virginia) has long been recognized as a natural phenomenon. The recent increase in shale gas extraction activities in these areas has highlighted the need to distinguish between baseline methane concentrations and those that may results from gas extraction activities. For the first time, this study shows that natural dissolved methane in Northeastern Pennsylvania exhibits a relationship with prevailing redox conditions of groundwater, though this relationship is not entirely as predicted. Specifically, methane concentrations in 806 pre-drill samples from residential water wells in Susquehanna County, NE Pennsylvania, were found to be highest in samples with low SO4 concentrations but low Fe(II) concentrations. This is opposite from what would be expected if high methane concentrations were associated with a reduction of insoluble Fe(III)-minerals resulting in the release of soluble Fe(II) (and therefore, an increase in measurable dissolved iron). The water type (i.e., Na-rich vs. Ca-rich), and topographic location (i.e., valley vs. upland) was also evaluated for each of the prevailing redox states to identify associations and potential driving factors. Based on this information, this talk identifies a combination of easily identifiable natural environmental "risk" factors (i.e., advanced redox state, Na-rich water type, and valley setting) that are highly predictive of naturally elevated methane concentrations in water wells. These findings highlight simple and meaningful relationships that may be used to infer whether methane in residential water sources is natural or associated with stray gas migration.

    Advanced prostate cancer is a phenotypically diverse disease that evolves through multiple clinical courses. PSA level is the most widely used parameter for disease monitoring, but it has well-recognized limitations. Unlike in clinical trials, in practice, clinicians may rely on PSA monitoring alone to determine disease status on therapy. This approach has not been adequately tested. Chemotherapy-naive asymptomatic or mildly symptomatic men (n=872) with metastatic castration-resistant prostate cancer (mCRPC) who were treated with the androgen receptor inhibitor enzalutamide in the PREVAIL study were analyzed post hoc for rising versus nonrising PSA (empirically defined as >1.05 vs ⩽1.05 times the PSA level from 3 months earlier) at the time of radiographic progression. Clinical characteristics and disease outcomes were compared between the rising and nonrising PSA groups. Of 265 PREVAIL patients with radiographic progression and evaluable PSA levels on the enzalutamide arm, nearly one-quarter had a nonrising PSA. Median progression-free survival in this cohort was 8.3 months versus 11.1 months in the rising PSA cohort (hazard ratio 1.68; 95% confidence interval 1.26-2.23); overall survival was similar between the two groups, although less than half of patients in either group were still at risk at 24 months. Baseline clinical characteristics of the two groups were similar. Non-rising PSA at radiographic progression is a common phenomenon in mCRPC patients treated with enzalutamide. As restaging in advanced prostate cancer patients is often guided by increases in PSA levels, our results demonstrate that disease progression on enzalutamide can occur without rising PSA levels. Therefore, a disease monitoring strategy that includes imaging not entirely reliant on serial serum PSA measurement may more accurately identify disease progression.

    Recently, a new implant surface texture, featuring application of nanometer-scale calcium phosphate has been shown to enhance early bone fixation and formation in preclinical studies and in human histomorphometric studies, which may be beneficial in immediate loading situations. The purpose of the present prospective clinical study was to, during 1 year, clinically and radiographically evaluate a nanometer scale surface modified implant placed for immediate loading of fixed prostheses in both maxillary and mandibular regions. Thirty-five out of 38 patients who needed implant treatment and met inclusion criteria agreed to participate in the study and were consecutively enrolled. Surgical implant placement requirements consisted of a final torque of a least 25 Ncm prior to final seating and an implant stability quotient above 55. A total of 102 NanoTite PREVAIL (NTP) implants (BIOMET 3i, Palm Beach Gardens, FL, USA) (66 maxillary and 36 mandibular) were placed by one investigator, and the majority of these were placed in posterior regions (65%) and in soft bone (69%). A total of 44 prosthetic constructions were evaluated consisting of 14 single-tooth restorations, 26 fixed partial dentures, and four complete fixed restorations. All provisional constructions were delivered within 1 hour, and the final constructions placed after 4 months. Implants were monitored for clinical and radiographic outcomes at follow-up examinations scheduled for 3, 6, and 12 months. Of the 102 study implants, one implant failed. The simple cumulative survival rate value at 1 year was 99.2%. The average marginal bone resorption was 0.37 mm (SD 0.39) during the first year in function. According to the success criteria of Albrektsson and Zarb, success grade 1 was found with 93% of the implants. Although limited to the short follow-up, immediate loading of NanoTite Prevail implants seems to be a viable option in implant rehabilitation, at least when a good initial fixation is achieved.

  10. Can Cooler Heads Prevail?

    The significant correlation between dropping temperatures throughout the Pliocene and the concomitant explosive expansion of the Hominid brain has led a number of workers to postulate climate change drove human evolution. Our brain (that of Homo sapiens), comprises 1-2 percent of our body weight but consumes 20 -25 percent of the body's caloric intake. We are "hotheads". Brains are extremely sensitive to overheating but we are endowed with unparalleled thermal regulation, much of it given over to protecting the Central Nervous System (CNS). Will there be reversed trends with global warming? The human brain has been shrinking since the end of the Ice Ages, losing about 150cc over the past 10,000 years. Polar bear skulls have been downsizing as well. Almost all mass extinctions or evolutionary upheavals are attributed to global warming: e.g. the Permian/Triassic (P/T) event, i.e., "The Great Dying", 250 million years ago (~90% of all life forms wiped out); the Paleocene/ Eocene Thermal Maximum (PETM) 55 million years ago. They may be analogs for what might await us. Large creatures, whose body size inhibits cooling, melted away during the PETM. Horses, initially the size of dogs then, reduced to the size of cats. An unanticipated hazard for humans that may attend extreme global warming is dumbing down or needing to retreat to the Poles as did those creatures that survived the P/T event (some references: http://johnhawks.net/research/hawks-2011-brain-size-selection-holocene; Kandel, E. et al Principles of Neural Science 4th ed.

  12. Setting the price for PV for the Advanced Renewable Tariffs program in Ontario

    McMonagle, R.

    2005-01-01

    Key considerations for the pricing of photovoltaic (PV) energy in an advanced renewable tariff (ART) program in Ontario were presented. This paper addressed solar industry fears concerning a financing mechanism for on-site solar generation in Ontario and its potential to fail if markets are not sufficiently prepared in advance. The mechanism could result in the creation of an unsustainable demand for solar products. It was suggested that in addition to building capacities in the industry, training and public education are important issues that the first phase of an ART's program must address. A 5 year pilot program was recommended in order to build industry infrastructure and capacity, before moving to rates based on the model developed by the Ontario Sustainable Energy Association. An initial price of 0.42 kWh was recommended to stimulate early adopters and to build capacity. It was noted that PV supplied power coincides with peak demand, and that its ART rate should reflect this premium cost value. Ontario ratepayers are already paying millions of dollars for electricity at rates higher than $0.42 per kWh. It was estimated that the average cost of the ART program for PV in the introductory stage would cost ratepayers under $10 million per year. While there have been no Canadian studies done on the value of PV's benefits to the power grid, Californian studies have indicated that benefits for Ontario should range between $0.20-$0.38 CAN per kWh. It was concluded that the price for PV in Ontario's ARTs program needs to be set at a high enough rate to stimulate the sustainable growth of the industry in the province. 10 refs., 3 tabs., 3 figs

    2013-01-01

    We can get an (energy efficiency) EE improvement if we produce a flatter daily load curve, leading to a higher efficiency of the power system, making better use of the generation and transport electricity chain, thus avoiding over-investment in equipment used just few hours a year. Tariff flexibility of the (Time of Use) TOU type is one of these measures. Generally, TOU systems are designed to minimize total system cost, which may cause losses in distribution companies (DISCOs), generating opposition. On the contrary, the present paper proposes a TOU system for electricity consumption in Chile where optimal prices are obtained in order to maximize total income of DISCOs. In this manner, the proposed TOU system is, by definition, beneficial for DISCOs and it may lead to a win–win situation among DISCOs and consumers. In particular, we show that such a system, implemented in a country like Chile, would allow for DISCOs a total potential benefit of 811.7 millions of dollars for the 3-year study period (2005–2007), considering initiatives that promote a 5% savings in real consumption during on-peak hours, obtained by the spread or difference between the proposed and the current systems. - Highlights: • We propose a TOU (Time of Use) system for electricity consumption in Chile. • In this system the optimal prices are obtained in order to maximize total income of (distribution companies) DISCOs. • The proposed TOU system may lead to a win–win situation among DISCOs and consumers. • This system, implemented in a country like Chile, would allow for DISCOs a total potential benefit of M$811.7. • Benefit obtained for 3-year study period with initiatives that promote 5% savings in real consumption during on-peak hours

    The issue of cross-subsidies and cost allocation practices concerns a large part of debates facing the deregulation of electric public utilities. The first aim of this paper is to deal with the regulation of an electric multi-product monopoly in association with equity and efficiency dimensions. To this end, we develop a concept and measure of improved equity. From a practical point of view, we also try to compute improved equity measurement considering the case of EDF tariff for domestic customers. (author)

    Efficient use of resources in organizations is one of the most important duties of managers. Appropriate allocation of resources can help managers to do this well. The aim of this study was to determine the cost of radiology services and to compare it with governmental tariffs (introduced by the Ministry of Health in Iran). This was a descriptive and applied study that was conducted using the retrospective approach. First, activity centers were identified on the basis of five main groups of hospital activities. Then, resources and resource drivers, activities, and hospital activity drivers were identified. At the next step, the activities related to the delivery of radiology process were identified. Last, through allocation of activities cost to the cost objects, the cost price of 66 services that were delivered in the radiology department were calculated. The data were collected by making checklists, using the hospital's information system, observations, and interviews. Finally, the data were analyzed using the non-parametric Wilcoxon test, Microsoft Excel, and SPSS software, version 18. The findings showed that from the total cost of wages, materials, and overhead obtained, the unit cost of the 66 cost objects (delivered services) in the Radiology Department were calculated using the ABC method (Price of each unit of Nephrostogram obtained $15.8 and Cystogram obtained $18.4). The Kolmogorov-Smirnov test indicated that the distribution of data of cost price using the ABC method was not normal (p = 0.000). The Wilcoxon test showed that there was a significant difference between the cost of services and the tariff of radiology services (p = 0.000). The cost of delivered services in radiology departments was significantly higher than approved tariffs of the Ministry of Health, which can have a negative impact on the quality of services.

  17. Determining appropriate feed-in tariff rates to promote biomass-to-electricity generation in Eastern Ontario, Canada

    Moore, Steven; Durant, Vincent; Mabee, Warren E.

    2013-01-01

    On-site data collection, interviews, and financial models were used to determine the feed-in tariff (FIT) rate required to encourage investment in the generation of electricity from currently unused biomass from the Eastern Ontario forest industry. A financial model was adapted and run to determine the net present value, internal rate of return, and payback period associated with a 15 MW biomass-to-electricity facility. The analysis suggests that Ontario should consider a stronger incentive than the recently-offered CDN$ 0.13 kW −1 h −1 for biomass-to-electricity. If no customer for heat generated from the plant can be found, FIT rates between CDN$ 0.17–0.22 kW −1 h −1 are necessary to achieve a 15% internal rate of return and a simple payback of approximately 5 yr; achieving a price of CDN$ 0.013 kW −1 of thermal output still requires elevated FIT rates between CDN$ 0.15–0.21 kW −1 h −1 to meet economic performance criteria. Other barriers, particularly regulations regarding the use of operating engineers in steam plants, should also be addressed to facilitate development of biomass-to-electricity. Without these changes, it is likely that biomass will be significantly under-used and will not contribute to the renewable energy goals of Ontario. - Highlights: • Economic performance of biomass-to-electricity generation in Ontario is assessed. • Feed-in tariffs needed to meet industrial payback and IRR targets are determined. • Existing feed-in tariff rates for biomass must be raised to meet industrial targets. • Incentives that adjust feedstock price might be explored to increase biomass use

  18. Impact of Battery Energy Storage System Operation Strategy on Power System: An Urban Railway Load Case under a Time-of-Use Tariff

    2017-01-01

    Full Text Available Customer-owned battery energy storage systems (BESS have been used to reduce electricity costs of energy storage owners (ESOs under a time-of-use (TOU tariff in Korea. However, the current TOU tariff can unintentionally induce customer’s electricity usage to have a negative impact on power systems. This paper verifies the impact of different BESS operation strategies on power systems under a TOU tariff by analyzing the TOU tariff structure and the customer’s load pattern. First, several BESS operation strategies of ESO are proposed to reduce the electricity cost. In addition, a degradation cost calculation method for lithium ion batteries is considered for the ESO to determine the optimal BESS operation strategy that maximizes both electricity cost and annual investment cost. The optimal BESS operation strategy that maximizes ESO’s net benefit is illustrated by simulation using an urban railway load data from Namgwangju Station, Korea. The results show that BESS connected to urban railway loads can negative impact power system operation. This is due to the high BESS degradation costs and lack of incentive of differential rates in TOU tariff that can effectively induce proper demand response.

  19. A method for the correction of the feed-in tariff price for cogeneration based on a comparison between Croatia and EU Member States

    Uran, Vedran; Krajcar, Slavko

    2009-01-01

    The European Commission has adopted Directive 2004/8/EC on the promotion of cogeneration, which the EU Member States, as well as candidates including Croatia, were obliged to accept. Among other terms and conditions, the Directive requires certain support mechanisms, such as feed-in tariff prices and premiums added to market electricity prices. In this paper, the cost effectiveness of selling electricity at the feed-in tariff prices in the selected EU Member States is compared to selling it on the European electricity market, with or without premiums. The results of this comparison will indicate whether correction of the Croatian feed-in tariff price to a higher value would be justified. The cost effectiveness ratio of a cogeneration unit upgraded with mean reverting and jump diffusion processes is used for comparison. At the end of this paper, a method is suggested for the correction of feed-in tariff prices, with examples of corrected prices for the years 2008 and 2009. Such corrections have been proven to be justified and are compared to the feed-in tariff prices in most of the selected EU Member States.

    2013-01-01

    The introduction of renewable energy sources in the electricity generation mix has the potential to reduce power sector's emissions and countries' dependence on imported oil. Climate change concerns and highly volatile oil prices have attracted governments' interest and support to sustain investments in renewable energy capacity, and different support policies have been implemented in many countries around the world. This paper analyzes the effects of investors' risk aversion on the performance of support schemes. The analysis compares two policy options, a feed-in tariff mechanism with a certificate market system. Results show that while a tariff mechanism could obtain better results than a certificate market, its performance is strictly dependent on regulator choices. A certificate market instead, permits to obtain the desired level of renewable energy market share with good cost-efficiency as long as investors' risk aversion is moderate. Moreover, discounting future cash flows with higher social discount rates further benefits a certificate system making it preferable to feed-in tariffs. - Highlights: ► Paper analyzes the performance of feed-in tariffs and certificate markets. ► Model simulates the evolution of a power system considering investors' risk aversion. ► Tariffs could obtain better efficiency but also low effectiveness or over-investment. ► Barriers to entrance could result in higher certificates prices. ► Certificate performances benefit from higher social discount rates

    After having recalled the legal context of objectives of this audit performed by the French Commission for Energy Regulation (CRE), this report proposes an analysis of GDF Suez's dissociated accounting which showed that costs are covered by natural gas regulated sale tariffs. In the second part, it comments the current market indexing used in tariff formula, comments current and present negotiations and their consequences for the market indexing share in long term contracts, discusses the issue of tariff volatility related to an increased market indexing share, discusses the possible re-examination of indices at the occasion of formula reviewing, and outlines that the diversified supplier portfolio allows optimisation operations. The third part addresses non-supply related costs: evolution of different infrastructure costs (related to distribution, transport, and storage) to be taken into account in regulated sale tariffs, evolution of commercial costs. Some recommendations are then made regarding the perspective of a tariff formula revision, and the perspectives of evolution of non-supply related costs

    The feed-in tariff has become a popular policy instrument globally for deploying clean energy, often involving substantial public spending commitments. Yet relatively little attention has been paid to how payments made under this policy type get distributed across socioeconomic groups. This paper links information on individual domestic photovoltaic (PV) installations registered under the feed-in tariff for England and Wales, to spatially-organised census data. This makes it possible to observe which socioeconomic groups are benefitting most and least under the policy. Comparing the observed benefit distribution to a counterfactual distribution of perfect equality, a moderate to high level of inequality is found. Cross-sectional regressions suggest that settlement density, home ownership status, physical dwelling type, local information spillovers, and household social class shaped this outcome. Greater sensitivity to these factors in policy design could improve distributional outcomes under feed-in tariff policies in England and Wales, and beyond. - Highlights: • Feed-in tariffs are subsidies involving substantial public spending commitments. • Payment distribution under the feed-in tariff in England and Wales has been substantially unequal. • Linking policy data to spatial census data can measure the degree of inequality. • Policy design that is more sensitive to participants’ socioeconomic characteristics can improve distributional outcomes.

    2005-03-01

    The separate impacts of the chronic diabetic state and the prevailing hyperglycemia on plasma substrates and hormones, in vivo glucose turnover, and ex vivo skeletal muscle (SkM) during exercise were examined in the same six dogs before alloxan-induced diabetes (prealloxan) and after 4-5 wk of poorly controlled hyperglycemic diabetes (HGD) in the absence and presence of approximately 300-min phlorizin-induced (glycosuria mediated) normoglycemia (NGD). For each treatment state, the approximately 15-h-fasted dog underwent a primed continuous 150-min infusion of [3-(3)H]glucose, followed by a 30-min treadmill exercise test (approximately 65% maximal oxygen capacity), with SkM biopsies taken from the thigh (vastus lateralis) before and after exercise. In the HGD and NGD states, preexercise hepatic glucose production rose by 130 and 160%, and the metabolic clearance rate of glucose (MCRg) fell by 70 and 37%, respectively, compared with the corresponding prealloxan state, but the rates of glucose uptake into peripheral tissues (Rd(tissue)) and total glycolysis (GF) were unchanged, despite an increased availability of plasma free fatty acid in the NGD state. Exercise-induced increments in hepatic glucose production, Rd(tissue), and plasma-derived GF were severely blunted by approximately 30-50% in the NGD state, but increments in MCRg remained markedly reduced by approximately 70-75% in both diabetic states. SkM intracellular glucose concentrations were significantly elevated only in the HGD state. Although Rd(tissue) during exercise in the diabetic states correlated positively with preexercise plasma glucose and insulin and GF and negatively with preexercise plasma free fatty acid, stepwise regression analysis revealed that an individual's preexercise glucose and GF accounted for 88% of Rd(tissue) during exercise. In conclusion, the prevailing hyperglycemia in poorly controlled diabetes is critical in maintaining a sufficient supply of plasma glucose for SkM glucose

    The author presents a tariff approach which will consider the nuclear assets of the French operator as a property belonging to the French citizens who accepted the development of these equipment and who, as consumers, have already largely paid these assets. He describes this market mechanism which would assign drawing rights to all competitors. This mechanism is inspired by the VVP Spanish instrument, bidding or auctioning instruments implemented in different countries, and the EDF's drawing right assignment mechanism. He highlights and discusses the benefits and drawbacks of such an instrument

    Heavy metals such as cadmium (Cd2+) affect microbial metabolic processes. Consequently, bacteria adapt by adjusting their cellular machinery. We have investigated the dose-dependent growth effects of Cd2+ on Rhizobium alamii, an exopolysaccharide (EPS)-producing bacterium that forms a biofilm on plant roots. Adsorption isotherms show that the EPS of R. alamii binds cadmium in competition with calcium. A metabonomics approach based on ion cyclotron resonance Fourier transform mass spectrometry has showed that cadmium alters mainly the bacterial metabolism in pathways implying sugars, purine, phosphate, calcium signalling and cell respiration. We determined the influence of EPS on the bacterium response to cadmium, using a mutant of R. alamii impaired in EPS production (MSΔGT). Cadmium dose-dependent effects on the bacterial growth were not significantly different between the R. alamii wild type (wt) and MSΔGT strains. Although cadmium did not modify the quantity of EPS isolated from R. alamii, it triggered the formation of biofilm vs planktonic cells, both by R. alamii wt and by MSΔGT. Thus, it appears that cadmium toxicity could be managed by switching to a biofilm way of life, rather than producing EPS. We conclude that modulations of the bacterial metabolism and switching to biofilms prevails in the adaptation of R. alamii to cadmium. These results are original with regard to the conventional role attributed to EPS in a biofilm matrix, and the bacterial response to cadmium. PMID:22096497

    Full Text Available Technological utopianism seduces many people, from the very origins of Western modernity –remember Francis Bacon’s island of Bensalem in his New Atlantis–, with the temptation of complete mastery over nature (which includes human immortality. Today, the prevailing mentality in the West, which tends to become a universal worldview, has much in common with the beliefs of the ancient Gnostics. According to this mindset, science and technology can allow the human mind to escape the limitations that characterize its natural state, releasing the anchor to biological stuff and escaping the human condition. In short, we would become gods –gods thought of as Immortal Super-Engineers. We must resist these destructive illusions and delusions, which means: technical rationality has to make his own critique of utopian reason (in the sense of Franz Hinkelammert. Without this self-criticism, a judicious use of techniques and technologies will be out of reach –and they do have an enormous potential for improving the human condition–, while avoiding –if it were still possible– the exterminist, nihilistic and suicidal drift of industrial civilization.

  7. Examining the financial performance of micro-generation wind projects and the subsidy effect of feed-in tariffs for urban locations in the United Kingdom

    2011-01-01

    This paper seeks to evaluate the effect of the upcoming 2010 UK Feed-in Tariff (UK FIT) on decentralised small wind-energy installations at the household and building level in urban locations. It is projected that the UK FIT will stimulate an unprecedented surge in building-mounted turbine installation. The tariff amount must stimulate incentive but mitigate the likelihood of distortions in the competitive electricity market. To analyse these issues, measured energy output from sites in the Warwick Wind Trials Project (WWTP) is converted into revenue in a net-present-value (NPV) framework for assessing commercial purchases of small wind systems. Variances in project variables are examined through NPV simulations using Monte Carlo analysis to capture permutations of small wind-project performance in the UK-with and without the UK FIT. Our research concludes that the proposed tariff amount of 30.5 p/kWh will not significantly boost the economic attractiveness of mildly selective (WWTP-based) sites in the UK. Furthermore, the fixed-tariff rate ( Pounds /kWh generated) could cause inefficiencies applied across uneven wind-resource distribution. The results of this study suggest further examination of policy related to micro-generation, in particular decentralised small wind projects. - Highlights: → Feed-in tariff (FIT) policy for urban UK small wind projects. → Determination of economic attractiveness (NPV) of projects. → Application of performance data from Warwick Wind Trials. → Need for higher tariff rate to provide average project with NPV>0. → Recommend reconsideration of FIT policy for urban small wind projects.

    Access to electricity is a major issue in West Africa. Governments have a difficult equation to solve. They naturally seek to offer their people a cheap kWh. But they are constrained by a production based largely on oil and therefore highly volatile production costs. How to fix an acceptable tariff, taking into account the investment needs required to expand the network and increase production? This analysis should provide some answers. The study presented in this paper provides a financial analysis of electricity utilities in West Africa. It allows a comparison of performances on a number of key financial ratios related to operations (Earning Before Interest Taxes Debt and Amortization/sales, working capital requirement/sales, days of receivables or payables), investment (net fixed assets/gross fixed assets), bank financing (financial structure, debt/EBITDA, interest expense/EBITDA) and economic and financial returns (Return On Capital Employed, Return On Equity). The conclusion focuses on the growth opportunity that the electricity sector could represent for each country. But this opportunity may only materialize if the EBITDA margins are restored. The available options appear limited and must be assessed taking into account the context of each country: tariff increase, improvement of technical losses or diversification into means of production no longer based primarily on oil or gas. - Highlights: > The study provides a financial analysis of electricity distribution companies in West Africa. > The study highlights generally insufficient EBITDA margins. > The study raises the question of tariffs and contribution to Gross Domestic Product of the electricity sector. > The conclusion focuses on the growth opportunity that the electricity sector could represent for each country.

  10. An initial analysis of options for a UK feed-in tariff for photovoltaic energy, from an array owner's viewpoint

    Plater, Steve

    2009-01-01

    The UK government has announced the introduction from April 2010 of a feed-in tariff (FIT) for renewable energy, and initiated a consultation on its design. This paper compares three possible variants of a UK FIT for rooftop photovoltaic (PV) arrays, on the basis of calculated income and array cost payback time, and for three locations (north, central and southern England) and various levels of household electricity consumption. This modelling is based on an FIT rate equivalent to Germany's. It concludes that an FIT which paid only for PV electricity surplus to on-site needs, and exported to the grid, would mean a simple payback time too long to make array purchase appealing. Preferable would be either export to the grid of all PV electricity for FIT payment; or a lower FIT rate for electricity used on-site, plus full FIT for any surplus exported. The latter would involve significantly lower costs in feed-in tariff payments. Finally, the effect of the UK government's illustrative FIT rate for consultation is examined for the same locations and annual consumption levels.

    The goal of this investigation was to characterize themanual and automated response of residential customers to high-price"critical" events dispatched under critical peak pricing tariffs testedin the 2003-2004 California Statewide Pricing Pilot. The 15-monthexperimental tariff gave customers a discounted two-price time-of-userate on 430 days in exchange for 27 critical days, during which the peakperiod price (2 p.m. to 7 p.m.) was increased to about three times thenormal time-of-use peak price. We calculated response by five-degreetemperature bins as the difference between peak usage on normal andcritical weekdays. Results indicatedthat manual response to criticalperiods reached -0.23 kW per home (-13 percent) in hot weather(95-104.9oF), -0.03 kW per home (-4 percent) in mild weather (60-94.9oF),and -0.07 kW per home (-9 percent) during cold weather (50-59.9oF).Separately, we analyzed response enhanced by programmable communicatingthermostats in high-use homes with air-conditioning. Between 90oF and94.9oF, the response of this group reached -0.56 kW per home (-25percent) for five-hour critical periods and -0.89 kW/home (-41 percent)for two-hour critical periods.

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

    2016-06-01

    After a presentation of the applicable legal framework, this report analyses the stakes of the elaboration of the future tariffs for the use of public electricity networks (TURPE): a strong increase of the production of renewable energies, a low growth of consumptions, a still high electric power peak, the existence of flexibility technologies which could allow a greater pro-activity of consumers, and an always higher number of consumers-producers. It presents the TURPE as a tool that goes along the evolution of network use modes: presentation of its main principles, discussion of power and energy as the both relevant variables for network tariffing. Then, the report describes how the TURPE will implement evolutions to face the stakes of energy transition: a higher taking into account of time and season in tariffs, the question of articulation between electric vehicles and networks, and the question of the articulation between self-production and networks. Several specific cost issues and aspects are more precisely addressed in appendix

    Incentive schemes for the development of renewable energy sources may focus on quantities (defining national targets and setting up bidding systems, or quota systems providing for green certificate trading), or they may focus on prices (feed-in tariffs). Whatever the system chosen, the role of the public authorities is quite specific: to stimulate technical progress and speed up the technological learning processes so that ultimately renewable energy technologies will be able to compete with conventional technologies, once the environmental costs have been internalized. A comparison of instruments must thus take into account the characteristics of the innovation process and adoption conditions (uncertainties regarding cost curves, learning effects) which means also looking at dynamic efficiency criteria. The paper concludes that a system of feed-in tariffs is more efficient than a bidding system, but highlights the theoretical interest of green certificate trading which must be confirmed through practice, given the influence of market structures and rules on the performance of this type of approach.

  15. Increasing Block Tariffs in an Arid Developing Country: A Discrete/Continuous Choice Model of Residential Water Demand in Jordan

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Arid developing countries face growing challenges from water scarcity, which are exacerbated by deficient piped water supply infrastructures. Increasing block tariffs (IBTs, charging higher rates with increasing water consumption, can potentially reconcile cost recovery to finance these infrastructures with an equitable and affordable sharing of the cost burden. A firm understanding of the impacts of varying prices and socio-economic conditions on residential water demand is necessary for designing IBTs that promote these objectives. Consistently estimating water demand under an IBT requires a discrete/continuous choice (DCC model. Despite this, few econometric studies of arid developing countries have applied this state-of-the-art approach. This paper applies a DCC model to estimate residential water demand under IBTs in the severely water-stressed country of Jordan, using 15,811 country-wide household-level observations from five years up to 2013. We extend Hewitt and Hanemann’s original DCC formulation in order to accommodate IBTs featuring a linearly progressive tariff block. We then use the resulting demand function to assess Jordan’s 2013 IBTs and alternative IBT designs. Under the estimated price elasticities, very few IBT designs achieve a full recovery of the financial costs of water provision, but we still identify a potential to improve cost recovery and affordability.

    2007-01-01

    In 2006 and 2007 Terasen Pipelines (Trans Mountain) Inc. (now Trans Mountain Pipeline Inc.) submitted a series of applications to the National Energy Board for revisions to the Trans Mountain Tariffs. They were filed in response to apportionment concerns on the Trans Mountain pipeline. Four of the applications involved pronounced and contentious changes to the capacity allocation procedures on the pipeline system. For ease of reference, the Board amalgamated its 4 decisions on these applications into a single document. A map of the Trans Mountain pipeline system as a whole was presented along with a detailed map indicating the delivery locations served by the system in the lower mainland of British Columbia and the state of Washington. The issues considered by the Board in each of these decisions included capacity allocation for Westridge Dock; capacity allocations to export destinations; common carriage requirements; and the need for creating a new barge subcategory. Relevant sections of the National Energy Board Act referred to in the decisions were highlighted. This document also listed the Trans Mountain Tariffs that have introduced notable revisions to the capacity allocation procedures on the system since September 2003. 16 refs., 2 figs., 3 appendices

    Different support instruments for renewable energy expose investors differently to market risks. This has implications on the attractiveness of investment. We use mean-variance portfolio analysis to identify the risk implications of two support instruments: feed-in tariffs and feed-in premiums....... Using cash flow analysis, Monte Carlo simulations and mean-variance analysis, we quantify risk-return relationships for an exemplary offshore wind park in a simplified setting. We show that feedin tariffs systematically require lower direct support levels than feed-in premiums while providing the same...

  19. Heart rate and respiratory rate influence on heart rate variability repeatability: effects of the correction for the prevailing heart rate

    Directory of Open Access Journals (Sweden)

    Jakub Sławomir Gąsior

    2016-08-01

    Full Text Available Background: Since heart rate variability (HRV is associated with average heart rate (HR and respiratory rate (RespRate, alterations in these parameters may impose changes in HRV. Hence the repeatability of HRV measurements may be affected by differences in HR and RespRate. The study aimed to evaluate HRV repeatability and its association with changes in HR and RespRate.Methods: Forty healthy volunteers underwent two ECG examinations seven days apart. Standard HRV indices were calculated from 5-min ECG recordings. The ECG-derived respiration signal was estimated to assess RespRate. To investigate HR impact on HRV, HRV parameters were corrected for prevailing HR. Results: Differences in HRV parameters between the measurements were associated with the changes in HR and RespRate. However, in multiple regression analysis only HR alteration proved to be independent determinant of the HRV differences – every change in HR by 1 bpm changed HRV values by 16.5% on average. After overall removal of HR impact on HRV, coefficients of variation of the HRV parameters significantly dropped on average by 26.8% (p < 0.001, i.e. by the same extent HRV reproducibility improved. Additionally, the HRV correction for HR decreased association between RespRate and HRV. Conclusions: In stable conditions, HR but not RespRate is the most powerful factor determining HRV reproducibility and even a minimal change of HR may considerably alter HRV. However, the removal of HR impact may significantly improve HRV repeatability. The association between HRV and RespRate seems to be, at least in part, HR dependent.

    The aim of this public consultation is to gather input from the market regarding the options envisaged by the CRE for the ATTM5 tariffs. These concern the tariff regulation framework, the level of tariffs and the structure of the tariff offerings of the LNG terminals. Items from the tariff documentation sent to the CRE by Elengy and Fosmax LNG would lead to a change in unit tariffs of -0.7% for Montoir, -13.9% for Fos Tonkin and -11.9% for Fos Cavaou. At this stage, with regard to the requests from Elengy and Fosmax LNG, the CRE is planning: - to adjust the trajectories of the net operational charges requested by the LNG terminal operators; - to decide on a weighted average cost of capital (WACC) equal to that of the transmission network operators, within a range from 4.75% to 5.5% actual before tax, plus a bonus reflecting the specific risks to LNG terminals, within a range from 1.0% to 2.4%. Depending on the rate of remuneration applied, and the direction of the net operational charges selected, the change in the ATTM5 tariff may be between -2.5% and -10.6% inclusive for Montoir, between -14.4% and -18.5% inclusive for Fos Tonkin and between -14.8% and -26.1% inclusive on average per year for Fos Cavaou. The CRE is planning the following schedule for drawing up the ATTM5 tariff and its entry into force: - this public consultation is open up to 14 October 2016; - the CRE's tariff deliberation, having consulted the French Higher Energy Council (CSE), will be adopted at the end of 2016; - the ATTM5 tariff will enter into force on 1 April 2017. At the same time as this public consultation, the CRE is publishing an audit of the request from LNG terminal operators on the rate of remuneration for the period of the ATTM5

    Full Text Available This paper discusses the comparative role of protectionism on Brazilian and Portuguese economic growth for the period 1860-1950 in the context of the available theoretical approaches from international economics. Although the role of tariffs has long been debated in the historiography of both countries, this paper provides the first exercise that uses a methodology based on a macro-econometric approach for long-run time-series. Given Clemens' and Williamson's conclusion that the world environment matters, we test their claim for two countries on the tariff reversal paradox. The Brazilian and the Portuguese experiences confirm that protection was correlated with growth in the period before World War I, and it is unlikely that freer trade would have increased Portuguese growth, contrary to the established thesis. The First World War, however, was a turning point for Brazil. In carrying out this study, we have used the best data available to us, occasionally departing from those used by Clemens and Williamson. Our conclusions hold for alternative data sets.Este artigo discute o papel comparativo do protecionismo sobre o crescimento econômico brasileiro e português no período 1860-1950 no contexto das aproximações teóricas disponíveis da Economia Internacional. Embora o papel das tarifas tenha sido longamente discutido na historiografia dos dois países, este artigo fornece o primeiro exercício que usa a metodologia baseada na aproximação macroeconométrica para sucessões cronológicas de longa duração. Dada a conclusão de Clemens e Williamson de que o enquadramento mundial conta, testamos para os dois países a sua pretensão do tariff reversal paradox. As experiências brasileira e portuguesa confirmam que a proteção esteve correlacionada com o crescimento no período anterior à Primeira Guerra Mundial, e não é provável que comércio mais livre tivesse aumentado o crescimento econômico português, contrariamente à tese

    Highlights: • M5P algorithm-based model determines influence of wind power on Spanish spot market. • Assessment of the wind power influence for different levels of wind resource. • Cost-benefit analysis is developed, accounting feed-in-tariffs and merit order effect. • The worst and best levels of wind power production for the system are determined. - Abstract: The incipient large-scale energy-storage technologies are not sufficiently developed yet, which means that the wind power production depends on the wind speed at every moment. This, along with the fact that the wind resource is not constant over time, makes wind power production quite variable. Therefore, an artificial intelligence-based technique (M5P algorithm) is applied to empirical hourly data to determine the influence of wind power technology on the spot market for different levels of wind resource in 2012. It concludes that wind power depressed the spot prices between 7.42 and 10.94 €/MW h for a wind power production of 90% and 110% of the real one, respectively. Furthermore, taking into account the important presence of wind power in the Spanish generation mix, the above range has been extended up to 0% in order to determine the worst and best level of wind power production for the Spanish electrical system (from an economical point of view). To do so, both feed-in-tariffs and wind power impact on spot market (merit order effect) have been accounted in accordance with the different levels of wind power production. Since empirical data from 2012 have been used to conduct the research, the results presented in this paper may provide policy makers with a worst and best-case scenario to discuss about the convenience of the last cutting expenses over wind power technology in Spain

  13. A Quasi-Feed-In-Tariff policy formulation in micro-grids: A bi-level multi-period approach

    Taha, Ahmad F.; Hachem, Nadim A.; Panchal, Jitesh H.

    2014-01-01

    A Quasi-Feed-In-Tariff (QFIT) policy formulation is presented for micro-grids that integrates renewable energy generation considering Policy Makers' and Generation Companies' (GENCOs) objectives assuming a bi-level multi-period formulation that integrates physical characteristics of the power-grid. The upper-level problem corresponds to the PM, whereas the lower-level decisions are made by GENCOs. We consider that some GENCOs are green energy producers, while others are black energy producers. Policy makers incentivize green energy producers to generate energy through the payment of optimal time-varying subsidy price. The policy maker's main objective is to maximize an overall social welfare that includes factors such as demand surplus, energy cost, renewable energy subsidy price, and environmental standards. The lower-level problem corresponding to the GENCOs is based on maximizing the players' profits. The proposed QFIT policy differs from the FIT policy in the sense that the subsidy price-based contracts offered to green energy producers dynamically change over time, depending on the physical properties of the grid, demand, and energy price fluctuations. The integrated problem solves for time-varying subsidy price and equilibrium energy quantities that optimize the system welfare under different grid and system conditions. - Highlights: • We present a bi-level optimization problem formulation for Quasi-Feed-In-Tariff (QFIT) policy. • QFIT dictates that subsidy prices dynamically vary over time depending on conditions. • Power grid's physical characteristics affect optimal subsidy prices and energy generation. • To maximize welfare, policy makers ought to increase subsidy prices during the peak-load

  14. The large-scale solar feed-in tariff reverse auction in the Australian Capital Territory, Australia

    Buckman, Greg; Sibley, Jon; Bourne, Richard

    2014-01-01

    Feed-in tariffs (FiTs) offer renewable energy developers significant investor certainty but sometimes at the cost of being misaligned with generation costs. Reverse FiT auctions, where the FiT rights for a predetermined capacity are auctioned, can overcome this problem but can be plagued by non-delivery risks, particularly of competitively priced proposals. In 2012 and 2013 the Australian Capital Territory (ACT) Government in Australia conducted a FiT reverse auction for 40 MW of large-scale solar generating capacity, the first such auction undertaken in the country. The auction was highly competitive in relation to price and demonstrating low delivery risks. Proposal capital costs, particularly engineering, procurement and construction costs, as well as internal rates of return, were lower than expected. The auction process revealed limited land availability for large-scale solar developments in the ACT as well as a significant perceived sovereign risk issue. The auction process was designed to mitigate non-delivery risk by requiring proposals to be pre-qualified on the basis of delivery risk, before considering FiT pricing. The scheme is likely to be used by the ACT Government to support further large-scale renewable energy development as part of its greenhouse gas reduction strategy which is underpinned by a 90-per cent-by-2020 renewable energy target. - Highlights: • Evolution of the reverse auction process in the Australian Capital Territory. • Analysis of the outcomes of the first Australian feed-in tariff reverse auction. • Identification of the major drivers of the low FiT prices achieved in the auction. • Identification of major issues that emerged in the auction

    This study investigates the merit order effect (MOE) of the recent years' implementation of solar power in Germany. Market clearing electricity prices and production levels are compared for the years 2009–2011, and a model for the relationship between the electricity price and price sensitive electricity production is developed and applied to predict electricity prices in Germany from July 2010 to July 2011 with and without solar electricity generation (SEG). The results show that the SEG has caused a 7% reduction in average electricity prices for this period. The average daily maximum price and daily price variation are also found to decrease, by 13% and 23%, respectively. When taking the MOE into account the net consumer's cost of the solar feed-in tariff (FIT) system is found to be 23% less than the charge listed in the electricity bill. The German FIT policy for solar power has been subject to considerable public debate, and a common argument brought up in disfavor of the system is the high cost for the consumers. In this study we demonstrate the importance of including the MOE when evaluating the total costs and benefits of the FIT policy mechanism. - Highlights: • The merit order effect (MOE) of the German solar feed-in tariffs (FITs) is analyzed. • Solar power is found to substitute thermal power on the margin in peak hours. • In a 1 year period, solar power has reduced electricity prices by 7%, on average. • The solar power has also reduced the daily price variation by 23%, on average. • When including the MOE, the net consumer's cost of solar FITs are reduced by 23%

    2016-01-01

    The key objective of this study is the examination of the regulatory and policy framework of the feed-in-tariff (FiT) scheme, specifically its effect on both the electricity pricing as well as the local and European renewable energy sources (RES) market, and accordingly the definition of its feasibility as a scheme for the further development and promotion of renewable energy technologies (RETs). This work discusses the FiT scheme implementation for photovoltaics (PVs) in four case study countries - Denmark, Germany, Cyprus, and Spain. A model describing the conditions under which a FiT scheme is led to collapse is also introduced and a parametric analysis towards revealing the sensitivity of the different parameters affecting it, is delivered. The study concludes with significant policy implications that should be considered for future implementation of the scheme. For the prevention of the collapse of the scheme, the tariff's value ought to be determined by each country's government based on a set of influencing factors including the operational, capital and investment costs of each RET, the standard cost of renewable energy (RE) generation and the avoidance cost, which would be regularly reviewed depending on the excess of the annual capacity. - Highlights: •Feasibility conditions of FiT schemes examined focusing on the treasury of 4 countries. •FiT's drawbacks led to its collapse less than a decade from its application. •Model for the prediction of the performance of the FiT scheme introduced. •Allocation of the economic growth to penetration rate affects FiT positively. •RES penetration into the energy mix has the highest impact on FiT's sustainability.

  17. Feed-in tariff design for domestic scale grid-connected PV systems using high resolution household electricity demand data

    Ayompe, L.M.; Duffy, A.

    2013-01-01

    The advent of large samples of smart metering data allows policymakers to design Feed-in Tariffs which are more targeted and efficient. This paper presents a methodology which uses these data to design FITs for domestic scale grid-connected PV systems in Ireland. A sample of 2551 household electricity demand data collected at 1/2-hourly intervals, electricity output from a 2.82 kW p PV system over the same time interval as well as PV system costs and electricity tariffs were used to determine the required FIT to make it worthwhile for the households to invest in the PV system. The methodology shows that it is possible to design single, multiple and continuous FITs. Continuous FITs are the most efficient and result in no overcompensation to the housholder while single and multiple FITs are less efficient since they result in different levels of overcompensation. In the PV case study considered, it was shown that the use of three FITs (0.3170, 0.3315 and 0.3475 €/kW h) resulted in a 59.6% reduction in overcompensation compared to a single FIT of 0.3475 €/kW h; assuming immediate and complete uptake of the technology, this would result in NPV savings of over €597 m to the Irish government over a 25 year lifetime. - Highlights: • Targeted and efficient FITs can be designed for domestic grid-connected PV systems. • The design is based on household electricity demand data at 1/2-hourly intervals. • Designs consist of single, multiple and continuous FITs. • Continuous FITs are most efficient with no overcompensation. • Multiple FITs result in lower overcompensation compared to a single FIT

    2017-01-01

    Over the past decade, feed-in tariffs have spurred significant deployment of solar photovoltaics in Germany and other countries. With recent cost trends, several countries are approaching retail grid parity. Some policymakers conclude that now is the time to remove feed-in tariffs, as grid parity creates a self-sustaining market, where economically rational investors will invest even in the absence of government incentives. Recent experience in key European solar markets, however, shows that with the advent of grid parity and the reduction of feed-in tariffs, investment in new solar capacity has decreased rather than increased, making it questionable whether low-carbon energy policy targets will be reached. We conduct a cross-case study analysis of three PV markets – Germany, Italy and Switzerland – to investigate the role of feed-in tariffs for the near- and post-grid parity stages of diffusion, accounting for investor diversity and distinguishing between implications for revenue-based and savings-based business models. We find that recent market trends are strongly driven by increased levels of risk, especially policy risk and exposure to revenue risk. We therefore suggest that relatively frugal but stable policy environments may be conducive to further growth of investment in photovoltaics and minimize cost to society. - Highlights: • Cost reductions of PV have led countries to move away from secure feed-in tariffs. • Exposure to higher risk reduces investment in PV deployment. • Revenue-based and savings-based business models are affected differently by risk. • Corporate, institutional and retail investors differ in their cost of capital. • If PV investor diversity shall be maintained, some risk mitigation is needed.

  19. Price regulation to remove EE-DSM disincentives and pressure for increased energy sales in monopoly segments of restructured electricity and gas markets: the multiple drivers target (MDT) tariff scheme

    Even in restructured markets a part of the energy business remains a monopoly and should be correctly regulated. We present an analysis which reveals common structures in schemes enacted in UK, Norway, Portugal and recently (on the basis of this study) in Italy. The identified structure, which we named Multiple Driver Target (MDT) regulation is a performance-based regulation scheme, which provides incentives for greater economic efficiency, without creating biases against environmental efficiency. The method relies on a statistical analysis of the correlation of utility costs and a few 'cost drivers' (e.g. number of customers served, grid length, sold or transported energy). We discuss how MDT can be used to set price levels and price changes in the regulatory period in such a way to correctly match the evolution of costs and avoid awarding unwanted signals to utilities. At the opposite, pure Price Cap regulation provides artificial incentives to utilities to increase energy sales (even if this is not economic for the customers nor for society ) beyond the predicted levels foreseen in the price fixing Rate Cases. We show that Under MDT regulation the reduction in profits due to reduced sales as a consequence of DSM is minimised. In so doing this procedure removes the most important disincentive for utilities to implement DSM programmes since lost profits due to reduced sales can be substantially higher than direct costs of DSM programmes; once MDT regulation is in place, also these direct costs can be recovered through a small part of the tariff. We also discuss how MDT can be implemented with a moderate effort by regulatory authorities. (author)

    It is known, that the kinetics of oxidation of zirconium at formed heating is characterized by two consecutive stages. At the initial stage the thin protecting film will be derived. The relation of its depth from time h (t) is described predominantly by parabolic law. Some time later there can be a transition to the linear law of oxidation. The time moment divided these areas on the kinetic relation is called as a point of break. The film is formed at the second stage, has a developed grid of pores or cracks, can be flake away and be crumbled by losing its protective properties. At the oxidation of the surface shells of the heat generating elements and the technological channels of atomic boilers both stages are proceeded simultaneously. This phenomenon is called modular corrosion. Its consequences can be dangerous for the equipment. Its mechanism is not clear till now. Similar dependencies h(t), with the break point, beginning from which the thin film is transformed into the thick one were found by us at the oxidation α-Fe with prevailing cubical texture. The task of the work was to study the oxide film growth laws in order to clarify the mechanisms of transition of the thin film into the oxide layer on the α-Fe surface and Zr-Nb alloy modular corrosion emergence. Low-carbonate steel with contents 99.43 % of α-Fe was used as a model object of our research. In the texture of the steel surface planar direction [100] was prevalent. Its part accounted for about 40 %. The isothermal air oxidation was carried out in the interval of 450-500 deg. C . Phase composition of the film was determined with X-ray diffraction. The mathematical treatment of the dependencies h(t) obtained by experiment showed that the kinetics of the film growth can be conditionally divided into 4-stages. The initial stage is described by function logarithmic function, the other stages - by the power mode h n =A n ·t, namely, the second stage - is described by function close to cubical (n≅3

    With the complete opening of natural gas markets to competition and the legal separation of distribution networks, Gaz de France Reseau Distribution requested the implementation of a new tariff of use of gas distribution networks to the Commission of energy regulation (CRE). A new tariff of networks utilisation has thus been proposed by CRE after a public consultation and the audition of gas suppliers. This tariff foresees a 5.6% increase of the present day tariff by July 1, 2008. The impact on the end-users' gas retail price will be a 1.5% rise of the regulated tariff. (J.S.)

    The present competition circumstances (ambient) require enterprises (companies or undertaking) like CERON to have understanding of all conditions to propose tariffs which give correct signal the consumers. Objective. Thus, search for valuations of model to define the tariff of electric energy based on marginal cost though a study in case of CERON. Method. Develop an investigation of a model of definition of tariffs of electric energy based on marginal costs to start the study in case of CERON and followed by analysis of its tariff structure. Results. With application of the signal (sign or indication) of tariffs, can measure the degree of separation of tariffs and to propose new modalities of alternate tariffs which offer conditions to reflect the real form of costs imposed by clients who form subgroups of tariffs of CERON. With final results, it offers parameters to trace (seek) important strategy for the company. Conclusion: The model gives condition's to identify and quantify of subsidies inside the tariff structure. It is a base which permits to create alternatives to resolve tariff distortions. It permits to have a better understanding which category (class) of consumers who are free will try to seek companies with tariffs which reflect really its costs. (author)

    2017-07-01

    Full Text Available With regulators’ growing interest in improving operational efficiency and quality supply, the time is nearing when performance based regulation will become norm for regulating the distribution tariff in Indian electricity distribution sector. In this context, the State Electricity Regulatory Commissions proposed replacing rate-of-return regulation with most commonly used performance based regulatory regime, i.e., Price Cap regulation also known as RPI-X (Retail Price Index - Productivity Offset regulatory framework. However, the potential problem associated with applying price cap regulation scheme in practice is the determination of productivity offset or X factor used in price caps setting. This paper proposed an approach to calculate the X-factor for 58 government-owned and privately-owned electricity distribution utilities in India during a five year period from 2007/08 to 2011/12. A Stochastic Frontier model through an input distance function is first applied to compute the Malmquist Total Factor Productivity (TFP and the estimated TFP is then used to calculate the utility-specific X-factor. With rely on calculated X-factor, the distribution utilities would be able to cap either on prices or revenues thus accounting the inflation in the tariff determination. This will be more realistic approach as compared to cost plus approach.

    We construct a model to optimize the economics of distributed generation photovoltaics (DGPV) for a parallel generation (behind-the-meter) application. Applying the model to the short-interval load and insolation data for two similar dairy operations in the U.S. Upper Midwest region, we find that highly site-specific differences in parameters lead to strikingly divergent results. Operating behind-the-meter strongly rewards real-time concurrence between on-site generation and on-site load. Compared to operating under a value of solar tariff (VOST) or net energy metering (NEM), we argue that parallel generation tariffs amplify the existing, irreducible uncertainties of project economics, and discourage DGPV investment. - Highlights: • Presents a novel approach to optimizing the size of behind-the-meter PV. • Demonstrates interaction of tax and financial parameters with load and insolation data. • Identifies how behind-the-meter operation raises risk to project economics.

  7. Unlocking the EUR53 billion savings from smart meters in the EU. How increasing the adoption of dynamic tariffs could make or break the EU's smart grid investment

    International Nuclear Information System (INIS)

    Faruqui, Ahmad; Hledik, Ryan; Harris, Dan

    2010-01-01

    We estimate the cost of installing smart meters in the EU to be EUR51 billion, and that operational savings will be worth between EUR26 and 41 billion, leaving a gap of EUR10-25 billion between benefits and costs. Smart meters can fill this gap because they enable the provision of dynamic pricing, which reduces peak demand and lowers the need for building and running expensive peaking power plants. The present value of savings in peaking infrastructure could be as high as EUR67 billion for the EU if policy-makers can overcome barriers to consumers adopting dynamic tariffs, but only EUR14 billion otherwise. We outline a number of ways to increase the adoption of dynamic tariffs. (author)

    Full Text Available The publication is aimed at developing the applied scientific foundations and instrumentarium for implementation of the new tariff terms in the practice of remuneration of employees in the budget sphere. On the basis of the identified problems of remuneration policy in the budgetary sphere, directions of its reform have been outlined. The importance of improving the tariff terms of remuneration together with developing new approaches to the designing a single tariff grid has been substantiated. The scientific-methodical recommendations on how to assess the complexity of tasks and responsibilities and to categorize them by the wage groups have been provided. It has been suggested that the complexity of tasks and responsibilities should be assessed using the points-factor evaluation method, which is applied in projecting the main wages, making use of grades. The factors for assessing the complexity of tasks and responsibilities according to different positions and jobs in the education sphere, science sphere, and science and technology sphere have been defined, the descriptive levels for certain factors have been developed. The assignment of posts and jobs to the qualifying groups upon the results of an assessment of the complexity of tasks and responsibilities has been determined. It has been concluded that use of the elaborated scientific-methodical recommendations would ensure decent remuneration, objective differentiation, transparency, and individualization of wages.

    Kitzing, Lena

    2014-01-01

    Different support instruments for renewable energy expose investors differently to market risks. This has implications on the attractiveness of investment. We use mean–variance portfolio analysis to identify the risk implications of two support instruments: feed-in tariffs and feed-in premiums. Using cash flow analysis, Monte Carlo simulations and mean–variance analysis, we quantify risk-return relationships for an exemplary offshore wind park in a simplified setting. We show that feed-in tariffs systematically require lower direct support levels than feed-in premiums while providing the same attractiveness for investment, because they expose investors to less market risk. These risk implications should be considered when designing policy schemes. - Highlights: • Mean–variance portfolio approach to analyse risk implications of policy instruments. • We show that feed-in tariffs require lower support levels than feed-in premiums. • This systematic effect stems from the lower exposure of investors to market risk. • We created a stochastic model for an exemplary offshore wind park in West Denmark. • We quantify risk-return, Sharpe Ratios and differences in required support levels

    In this report, we make an evaluation of the energy component of the central grid tariff and the use of marginal loss rates. We will first review the theory of optimum transmission tariffs and describes how the marginal loss rates are calculated and how these are used in combination with the system price in the current transmission costs. We describe the trend in the Swedish marginal loss schedule, and we refer the very short development in the PJM area (U.S. east coast). As the Swedish and the Norwegian system is apparently based on the same principles, we problematize the lack of harmonization, since the systems actually are now very different. There is little doubt that Statnett has refined and improved methods for calculating the marginal loss rates, while ensuring that bottlenecks are still handled fairly easy by a few large price areas on Nord Pool Spot. We discuss the relationship between loss-tariff and congestion management, and we recommend that Statnett considering using the area price as the settlement price. This will make it much easier for operators to take account of losses. (Author)

  13. Fostering the use of renewable energies in the European Union: the race between feed-in tariffs and green certificates

    International Nuclear Information System (INIS)

    Ringel, M.

    2006-01-01

    Fostering the use of renewable energies for power generation is at the heart of the EU's long term energy policy. Accordingly, the European Commission and literally all member states have set up ambitious installation targets for alternative energy sources. These aims can only be reached by recurring to support systems that help covering the cost disadvantages faced on liberalised electricity markets. Currently, a dichotomy of support models exists: Feed-in tariffs on the one side and green certificates on the other side seem promising tools to foster renewable energies. In this contribution we look closely at the concepts of both models as well as their advantages and disadvantages in terms of ecological effectiveness and economic efficiency. It becomes obvious that in the context of the liberalised power markets and the rush for the harmonisation of the instruments it will depend very much on in-detail regulations whether the installation targets will be met-regardless of the basic choice of model.

  14. Reverse Revenue Sharing Contract versus Two-Part Tariff Contract under a Closed-Loop Supply Chain System

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The importance of remanufacturing has been recognized in research and practice. The integrated system, combining the forward and reverse activities of supply chains, is called closed-loop supply chain (CLSC system. By coordination in the CLSC system, players will get economic improvement. This paper studies different coordination performances of two types of contracts, two-part tariff (TTC and reverse revenue sharing contract (RRSC, in a closed-loop system. Through mathematical analysis based on Stackelberg Game Theory, we find that it is easy for manufacturer to improve more profits and retailer’s collection effects by adjusting the ratio of transfer collection price through RRSC, and we also give the function to calculate the best ratio of transfer collection price, which may be a valuable reference for the decision maker in practice. Besides, our results also suggest that although the profits of the coordinated CLSC system are always higher than the contradictory scenario, the RRSC is more favorable to the manufacturer than to the retailer, as results show that the manufacturer will share more profits from the system through RRSC. Therefore, RRSC has attracted the manufacturers more to closing the supply chain for economic consideration.

    The Chinese government initiated the Feed-In Tariff (“FIT”) policy for downstream power generation in August 2013. The effectiveness of the downstream FIT policy has attracted the attention of academia and government. Using the quarterly data of listed solar PV companies between 2009 and 2015, this paper provides an empirical analysis regarding the effects of the downstream FIT policy. We find that (1) the FIT policy has significantly enhanced the inventory turnover of listed PV firms and improved their profitability; (2) the FIT policy has significant effects on the inventory turnover of midstream companies and mixed industry-chain companies mainly engaged in downstream operations; (3) FIT policy is more favorable towards increasing the inventory turnover of private enterprises. Our results indicate that the FIT policy can have substantial effects on the sustainable development of China's solar photovoltaic industry. - Highlights: •The article focuses on the analysis of the effect of downstream FIT policy. •We test how FIT policy affects overcapacity and profitability of solar PV companies. •We find FIT policy significantly solved the overcapacity of China’s solar PV industry. •We find FIT policy improved profitability of listed solar PV companies. •FIT policy can’t be played alone and should be combined with taxation and R&D policy.

    The European Union has yet to determine how exactly to reach its greenhouse gas emissions targets for the future. One potential answer involves large-scale development of concentrated solar power (CSP) in the North African region, transmitting the power to Europe. CSP is a relatively young and little utilized technology and is expensive when compared to other methods of generation. Feasibility studies have shown it is possible to generate enough power from CSP plants in Africa to spearhead the EUs climate goals. However, the costs of such a project are less well known. Currently, CSP must compete with low cost coal-fired electricity plants, severely hindering development. We examine the possible investment costs required for North African CSP levelized electricity cost to equal those of coal-fired plants and the potential subsidy costs needed to encourage growth until the technologies reach price parity. We also examine the sensitivity of investment and subsidies to changes in key factors. We find that estimates of subsidy amounts are reasonable for the EU and that sensitivity to such factors as perceived risk and learning rates would enable policy-makers to positively influence the cost of subsidies and time required for CSP to be competitive with coal.

    Statin treatment may impair glucose homeostasis and increase the risk of new-onset diabetes mellitus, although this may depend on the statin, dose and patient population. We evaluated the effects of pitavastatin 4 mg/day on glucose homeostasis in patients with metabolic syndrome in the CAPITAIN trial. Findings were validated in a subset of patients enrolled in PREVAIL-US. Participants with a well defined metabolic syndrome phenotype were recruited to CAPITAIN to reduce the influence of confounding factors. Validation and comparison datasets were selected comprising phenotypically similar subsets of individuals enrolled in PREVAIL-US and treated with pitavastatin or pravastatin, respectively. Mean change from baseline in parameters of glucose homeostasis (fasting plasma glucose [FPG], glycated hemoglobin [HbA1c], insulin, quantitative insulin-sensitivity check index [QUICKI] and homeostasis model of assessment-insulin resistance [HOMA-IR]) and plasma lipid profile were assessed at 6 months (CAPITAIN) and 3 months (PREVAIL-US) after initiating treatment. In CAPITAIN (n = 12), no significant differences from baseline in HbA1c, insulin, HOMA-IR and QUICKI were observed at day 180 in patients treated with pitavastatin. A small (4%) increase in FPG from baseline to day 180 (P validation dataset (n = 9), no significant differences from baseline in glycemic parameters were observed at day 84 (all comparisons P > 0.05). Similar results were observed for pravastatin in the comparison dataset (n = 14). Other than a small change in FPG in the CAPITAIN study, neutral effects of pitavastatin on glucose homeostasis were observed in two cohorts of patients with metabolic syndrome, independent of its efficacy in reducing levels of atherogenic lipoproteins. The small number of patients and relatively short follow-up period represent limitations of the study. Nevertheless, these data suggest that statin-induced diabetogenesis may not represent a class effect.

    Japanese electric demand has been steadily increasing in accordance with the economic growth. However, Japanese electric utilities are facing several problems; increasing construction cost of power facilities, siting constraints and the environmental issue of greenhouse gas emissions. To overcome these problems, electric utilities have been promoting demand-side-management (DSM) activities as well as supplier-side measures, with some presently being carried out through promoting energy conservation technologies and introducing electric tariff options of specific contracts for residential/commercial and industrial consumers. Japanese electric utilities have been carrying out R and D for the future, in particular, energy storage and heat storage which contribute to the improvement of load factor. In this paper, I would like to outline the R and D options for DSM in Japan. (author)

    Corporations and other institutions have contracted for more than 2300 MW of off-site solar, using power purchase agreements, green tariffs, or bilateral deals with utilities. This paper examines the benefits, challenges, and outlooks for large-scale off-site solar purchasing in the United States. Pathways differ based on where they are available, the hedge value they can provide, and their ease of implementation. The paper features case studies of an aggregate PPA (Massachusetts Institute of Technology, Boston Medical Center, and Post Office Square), a corporation exiting their incumbent utility (MGM Resorts), a utility offering large scale renewables to corporate customers (Alabama Powers Renewable Procurement Program), and a company with approval to sell energy into wholesale markets (Google Energy Inc.).

    2013-01-01

    Feed-in tariffs have been the main policy instrument applied in Portugal for the promotion of electricity produced from renewable energy sources under the EU Directives on energy and climate regulation. In this paper, we provide an empirical impact assessment of the economic and environmental effects of Portugal's FITs policy to promote RES-E generation. Impact assessment of policy instruments plays a crucial role on decision-making process. For numerical simulations, we make use of a hybrid top-down/bottom-up general equilibrium modeling approach, which represents a reliable tool to analyze the complex interactions between economic, energy, and environmental issues related to energy policies. Numerical simulations confirm the empirical evidence that the FITs policy implemented by Portugal was both an effective and a cost-efficient way to increase the generation of electricity from renewable energy sources and thus to achieve the national RES-E target of 45% in 2010. Results show relatively modest macroeconomic impacts indicating potentially low economic adjustment costs. From an environmental perspective, the deployment of renewable energy source results in significant carbon emissions reductions. - Highlights: ► We provide an impact assessment of Portugal's FITs policy to promote RES-E generation. ► For numerical simulations, we make use of a hybrid top-down/bottom-up general equilibrium model. ► Portugal's FITs policy proved to be a cost-efficient way to increase generation of renewable electricity. ► Results show relatively modest macroeconomic effects indicating potentially low economic adjustment costs. ► The deployment of renewable energy sources results in significant carbon emission reductions

  2. A new methodology for establishing a system for cross-border transmission tariffication in the internal electricity market

    2001-01-01

    Several organisations are working on a scheme for cross-border tariffication as the so-called Florence forum indicates. So far, a provisional concept created by ETSO (European Transmission System Operators) evolved which is oriented towards covering costs but is not quite cost-reflective and does not produce economic signals for the market players. In the present project a flow-oriented model and a corresponding methodology have been developed which derive compensations within super nodes standing for aggregated networks of the countries along transit and domestic paths. Specific fees are derived from overall network costs but may be applied in a flexible way to represent the realistic usage of the horizontal network for transits and domestic supply. Charging of costs can be oriented towards consumers or generators. A combination of shares of costs originally determined for consumers and generators is also possible. In such a way the model is flexible to fulfill the requirements of regulators, operators and the European Commission. Measured flow data of the UCTE network have been provided to check the concept in various directions, i.e. based on different parameters such as uniform and individual postage stamps, compensations for transits only and more elaborate networks of super nodes. The concept is also able to cope with circular flows within the real UCTE network. The methodology is suited for an application in a decentralised fashion as the transmission system operator needs to communicate with its neighboring operator only, i.e. there is no need for a centralised clearing office.

  3. Feed-in Tariff Pricing and Social Burden in Japan: Evaluating International Learning through a Policy Transfer Approach

    2017-10-01

    Full Text Available Feed-in tariff (FiT policy approaches for renewable energy (RE deployment are employed in many nations around the world. Although FiTs are considered effective in boosting RE deployment, the issue of increasing energy bills and social burden is an often-reported negative impact of their use. The FiT has been employed in Japan since 2012, following after many developed countries, and, as was experienced in other nations, led to a social burden imparted on society significantly higher than initial government estimates. Although policy decision making does not necessarily reflect international policy experience, it is still prudent to ask how international policy experiences of social burden increase were considered within the Japanese approach. In this research, we analyzed the transfer process by adapting a conventional model to develop more objective observations than was previously possible, by setting a benchmark for evaluation based on prior international experiences. We identified two streams of policy transfer, each led by different actors; the government and representatives of the National Diet of Japan (Diet. Both actors were exposed to the same experiences, however the interpretation, application to policy development and priority settings employed were vastly different. Although the framework can only assess policy learning processes, we have found that the government undertook a reasonable and rational process toward learning, while, on the other hand, the modified bill developed by the Diet members did not thoroughly derive learnings in the same way, due to cognitive and political reasons, and specifically, the issue of limiting social burden was not addressed.

  4. The influence of a Renewable Energy Feed in Tariff on the decision to produce biomass crops in Ireland

    2012-01-01

    A target of 30 per cent substitution of biomass for peat in the three peat fired power stations from 2015 has been set by the Irish Government. However, a knowledge gap exists on the extent to which Irish farmers would actually choose to grow these crops. An extension of the Renewable Energy Feed in Tariff (REFIT) scheme to include the co-firing of biomass with peat in electricity generation would enable the power stations to enter into Power Purchase Agreements (PPAs). These offer a fixed price to farmers for biomass feedstock. The decision to adopt biomass is represented as a constrained problem under certainty with the objective of profit maximisation. The results showed that the price offered under a PPA has a large effect on the economic returns from biomass crops. The price that the power stations previously estimated they would be able to pay, at €46 and €48 per tonne for willow and miscanthus, respectively, was used as a starting point. At this price the number of farmers who would choose to adopt biomass production is insufficient to achieve the national co-firing target. The target could be achieved at €70 and €65 per tonne for willow and miscanthus, respectively. - Highlights: ► We model the decision of Irish farmers to produce biomass crops. ► Current prices will lead to insufficient adoption to achieve policy targets. ► REFIT mechanism can succeed in meeting policy goals. ► Willow prices need to increase by approximately 27 per cent. ► Miscanthus prices need to increase by approximately 8 per cent.

    Full Text Available The aim of the study is to analyze the youngest in the world competitive market of electric energy and power of Russia. The hypothesis that there is a significant time lag between the launch date regulated competitive energy market and the actual state of its transition to a stationary operation. To test the hypothesis covered the electric energy consumer’s reaction on tariffs changes in the UES of the Ural in the period of time after restructuring RJSC “UES of Russian Federation”. Factual data of UES of Russia’s System operator shows how indicator values of electric energy consumption elasticity changes: consuming turns from elastic to inelastic according to price. Proved that in 2014 the energy demand matches to a competitive market. As a methodical research tool used 5 types of regression analysis equations for time series of electricity consumption, in addiction by the rate of the day-ahead market for 2009-2014. The research found that the transition to a competitive market of electricity production in Russia in fact was didn’t carried out in 2008, but was carried in 2014. Research proved that the electricity market regression analysis applied in predicting short periods of time (day-ahead market, because by increasing the time interval of forecasting accuracy of the forecast is decreases. The research results have great practical significance for the power industry subjects, especially those with high energy intensity of production, as the increase in the accuracy of forecasting reduces fines and total costs for electricity.

  7. Challenges with the public policy of measuring assets to set tariffs in the electricity sector: should someone benefit and someone be sacrificed?

    Directory of Open Access Journals (Sweden)

    Maria Elisabeth Moreira Carvalho Andrade

    2017-07-01

    Full Text Available ABSTRACT This paper contributes by encouraging discussions about the public policy of setting tariffs for public services based on the value of the investment made by the providers of these services. The purpose of this study was, in an unprecedented way and by combining theories of equity valuation and finance, to identify the asset valuation method that can lead to a fair value and balance between an affordable price for the consumer and an adequate return on investment for the concessionaires. The value assigned to these assets affects the tariff in two ways: (i via depreciation/amortization, which affects the cost of service; (ii via the return on investment, which is the portion that corresponds to the investor’s profit. We analyzed the Brazilian electricity sector, in which the rates set by the Brazilian Electricity Regulatory Agency (ANEEL currently use the new replacement value (NRV approach. We carried out empirical tests using data available on the ANEEL website from the second cycle periodic tariff review and information obtained in financial statements from 1995 onwards. The analysis included the NVR and restated historical cost (RHC methods, the latter being updated by the extended consumer price index (IPCA. After the descriptive and statistical analyses, we used the test of means to verify the differences between the variables in terms of NRV vs. RHC. The first conclusion was the absence of a significant difference between the NRV and RHC methods; that is, on average, the replacement price showed no significant difference to what would be the pure and simple restatement of assets. But this was found to hide something relevant, the fact that this average is derived from two main groups: that of the consumers who are paying more for energy services than they should, which constitutes a visible benefit to investors and loss for these consumers, and that of the consumers who are paying less than they should, which benefits them but

    Remote monitoring of cardiac implantable electronic devices has been demonstrated to safely reduce frequency of hospital visits. Limited studies are available evaluating the economic impact. The aim of this article is to highlight the social impact and costs for the patients associated with hospital visits for routine device follow-up at the enrollment visit for the TARIFF study (NCT01075516). TARIFF is a prospective, cohort, observational study designed to compare the costs and impact on quality of life between clinic-based and remote care device follow-up strategies. Two hundred nine patients (85.2 % males) were enrolled in the study; 153 patients (73.2 %) were retired, 36 (17.2 %) were active workers, 18 (8.6 %) were housewives, and 2 (1.0 %) were looking for a job. Among active workers, 63.9 % required time off from work to attend the hospital visit, while 67.0 % of all patients had to interrupt daily activities. The majority of patients spent half a day or more attending the visit. A carer accompanied 77 % of patients. Among carers, 36.6 % required time off from work, and 77.6 % had to interrupt daily activities. Median distance traveled was 36 km. The average cost of travel was 10 euros with 25 % of patients spending more than 30 euros. Data from patients enrolled in the TARIFF registry confirm that there are social and economic impacts to patients attending routine device checks in hospital which can be significantly reduced by using a remote monitoring strategy.

    Highlights: • Storage-based demand response (loadshifting) is underutilized in residential sector. • Economics (arbitrage savings versus equipment cost) are not well understood. • Stochastic demand models and real-life tariffs can illuminate economic viability. • A range of available storage options provide economically viable DR. • Daily/seasonal stochastic demand variations crucial to understanding optimum capacity. - Abstract: Demand response (DR) is one of many approaches to address temporal mismatches in demand and supply of grid electricity. More common in the commercial sector, DR usually refers to reducing consumption at certain hours or seasons, thus reducing peak demand from the grid. In the residential sector, where sophisticated appliance-level controls such as automatic dimming of lights or on-demand lowering of air conditioning are less common, building-based electricity storage to shift grid consumption from peak to off-peak times could provide DR without requiring consumers to operate their appliances on shifted or reduced schedules: Storage would be dispatched to appliances as needed while still shaving peaks on the grid. Technologically, storage and two-way-inverters are readily available to enable such residential DR. Economically, however, the situation is less clear. Specifically, are time-varying electricity tariffs available such that electricity cost reduction via arbitrage could offset manufacturing, financing, and installation costs of the required storage? To address this question we (i) devise an agent-based appliance-level stochastic model to simulate the electricity demand of an average U.S. household; (ii) loadshift the demand via simple dispatch strategies; and (iii) determine potential profits to the building owner, i.e. reduced electricity cost of the modified demand with realistic tariffs (Con Edison, NY) minus storage cost. We determine the economic viability for a range of traditional and advanced storage technologies

    2017-07-01

    The National Association of energy retailer operators (ANODE) brought proceedings to the Conseil d'Etat arguing that the decree of 16 May 2013 regarding regulated tariffs for the supply of natural gas was 'ultra vires'. The ANODE submitted that this tariff regulation breached European Union Law. Applying the findings of the preliminary ruling of 7 September 2016 given in this matter by the European Court of Justice, the Conseil d'Etat, in today's decision, annulled the decree of 16 May 2013 on the grounds that the imposition of a natural gas tariff regulation infringed European Union Law. In light of the great uncertainty that would affect contracts signed by millions of consumers as a result of such an annulment, and with regard to the necessity to prevent the legal insecurity that would ensue, the Conseil d'Etat has judged, exceptionally, that the past effects of this decree, which ceased to apply on 1 January 2016, must nevertheless be regarded as irrevocable

  17. Ruminant production systems in developing countries: Resource utilization

    International Nuclear Information System (INIS)

    Devendra, C.

    1989-01-01

    Ruminant production systems are discussed with specific reference to the resource utilization required to support them. Particular focus is placed on the main production resources (animals and feeds) and their underutilization. The ruminant animals include buffaloes, cattle, goats, sheep and camels. With the exception of cattle and sheep, their numbers in developing countries account for between 94 and 100% of total world population. Their biological attributes, including inherent characteristics, feeding behaviour and metabolism, are summarized. The extent and availability of feed resources are considered; resources include permanent pastures, crop residues, agroindustrial by-products and non-conventional feeds. The prevailing ruminant production systems are classified into three main categories: extensive systems, systems incorporating arable cropping (roadside, communal and arable grazing systems; tethering and cut-and-carry feeding), and systems integrated with tree cropping. Their genesis and endurance with patterns of crop production and farming systems are discussed. Integrated systems, involving animals and tree crops, are potentially important. Prevailing ruminant production systems are unlikely to change in the foreseeable future, unless there are major shifts in resource use and the proposed new systems are demonstrably superior. Factors likely to influence future ruminant production systems are market requirements, available feed resources and growth in human populations. Two associated strategies for improvement are proposed: increased priority to buffaloes, goats, sheep and camels, consistent with their potential contribution to meat, milk and fibre supplies and draught power; and more complete utilization of the available feed ingredients and increased feed supplies

    influenced and ultimately determined the price or tariffs for electricity to customers, were generally the same. Utilities revenue requirements were founded upon complex 'cost of service' formulas which emphasized and allowed the recovery of all 'reasonable' costs including operating expenses, taxes, depreciation of investments and additionally assured a reasonable rate or return on all outstanding investments. The consequence was that, through regulation of electric rate design, the ultimate price of electricity was determined by the aggregate of costs to produce it, independent of the forces of supply and demand. Through the examination of the major principles and features of regulated compared to unregulated electric markets such as the 'obligation to serve' and the 'cost of service', this presentation will address and discuss the economic opportunities and risks associated with nuclear power plants operating in deregulated, competitive electric generation markets. In transitioning to competitive markets, a number of key economic questions will be raised that will emphasize nuclear plant economic requirements for a profitable enterprise, addressing factors such as, plant operating performance, market conditions, energy price, key economic measures, investment opportunities, nuclear asset valuation and plant life extension. An economic analysis of a recent nuclear power plant valuation study will be presented including a discussion of key input variables, financial assumptions, economic results and a brief demonstration of an interactive, PC based computer model used for the analysis. A similar model, is currently being considered by the IAEA to evaluate the economics of nuclear power plant life extension along with alternative generation approaches. In closing, a number of short and long term prospects for the future of nuclear power will be discussed including plant life extension and the prognostication of a new electric generation business model concept

    The aims of this study were to estimate the cost of surgical treatment of fractures of the proximal humerus using a micro-costing methodology, contrast this cost with the national reimbursement tariff and establish the major determinants of cost. A detailed inpatient treatment pathway was constructed using semi-structured interviews with 32 members of hospital staff. Its content validity was established through a Delphi panel evaluation. Costs were calculated using time-driven activity-based costing (TDABC) and sensitivity analysis was performed to evaluate the determinants of cost The mean cost of the different surgical treatments was estimated to be £3282. Although this represented a profit of £1138 against the national tariff, hemiarthroplasty as a treatment choice resulted in a net loss of £952. Choice of implant and theatre staffing were the largest cost drivers. Operating theatre delays of more than one hour resulted in a loss of income Our findings indicate that the national tariff does not accurately represent the cost of treatment for this condition. Effective use of the operating theatre and implant discounting are likely to be more effective cost containment approaches than control of bed-day costs. This cost analysis of fractures of the proximal humerus reinforces the limitations of the national tariff within the English National Health Service, and underlines the importance of effective use of the operating theatre, as well as appropriate implant procurement where controlling costs of treatment is concerned. ©2016 The British Editorial Society of Bone & Joint Surgery.

These proposals have been adopted and are the object of three legislative texts: the decree no. 2005-607 from May 27 2005 relative to the tariffing rules, the by-law from May 27, 2005 relative to the definition of balancing areas, and the advice from May 27, 2005 relative to the tariffs of use of natural gas transportation networks. In application of article 7 of the law from January 3, 2003, the implementation of the first tariffs of use of natural gas transportation networks and of liquefied natural gas (LNG) facilities is defined in the decree no. 2004-994 from September 21, 2004. On the main transportation network, the tariffing is of 'input-output' type and does not depend on the distance, while at the regional network scale, the tariffing is linked with the distance. The tariff of use of LNG facilities is the sum of 4 terms: a fixed term applied to each batch unloaded at the methane terminal, a term proportional to the unloaded LNG quantities, a term depending on the duration of use of LNG storage facilities and a term covering the gas consumptions of LNG facilities. This document gathers these different legislative texts with their appendixes. (J.S.)

    The study examines groups of 15-16-year-old students whose attitudes toward drug use are out of line with the prevailing norms. It analyzes data from eight countries from the 2003 European School Survey on Alcohol and Other Drugs (ESPAD): Bulgaria, the Czech Republic, Hungary, France, Malta, Slovenia, Sweden, and the United Kingdom. In those countries, 22,900 15-16-year-old pupils answered the ESPAD questionnaire. Groups of subjects whose responses are far removed from the modal value are sought and studied. The aim is to explore "rare answers" compared to what is perceived by the majority of students. In order to explore what can lead a pupil to an atypical perception of risk, a cluster analysis, based on the risk perceptions of alcohol, tobacco, and cannabis use, was run to isolate the groups in which pupils tend to answer differently. Six clusters were established classifying students into those who failed to respond, deny the risks, do not know about the risks, see any drug use as great risk, see regular use as great risk, and who see a moderate risk for most frequencies of use. The nonresponders, risk deniers, and those ignorant of the risks are infrequent making up, in all, only 16.9% of the total sample. Gender, country, alcohol use, cannabis use, tobacco use, and friends' consumption were used to describe both the individual risk perceptions and the clusters based on them. Both global context (country) and "micro" context (frequencies of drug use, peers lifestyle, and parental permissiveness) appear to play a major role in the risk perception of drug use.

    To assess benefit and harms of adding an eHealth intervention to health education and individual counseling in adolescents with congenital heart disease. Randomized clinical trial. Denmark. A total of 158 adolescents aged 13-16years with no physical activity restrictions after repaired complex congenital heart disease. PReVaiL consisted of individually tailored eHealth encouragement physical activity for 52weeks. All patients received 45min of group-based health education and 15min of individual counseling involving patients' parents. The primary outcome was maximal oxygen uptake (VO2 peak) at 52weeks after randomization. The secondary outcome was physical activity. Exploratory outcomes were generic and disease-specific questionnaires. In the intervention group, 58 patients (72%) completed the final test, but of those, only 46 (57%) fulfilled the compliance criteria of using the eHealth application for at least 2 consecutive weeks. In the control group, 61 patients (79%) completed both exercise tests. Adjusted for baseline values, the difference between the intervention group and the control group in mean VO2 peak at 1year was -0.65ml·kg(-1)·min(-1) (95% CI -2.66 to 1.36). Between-group differences at 1year in physical activity, generic health-related quality of life, and disease-specific quality of life were not statistically significant. Adding a tailored eHealth intervention to health education and individual counseling did not affect outcomes among adolescents with congenital heart disease. Our results do not support the use of this eHealth intervention in adolescents with complex congenital heart disease. Clinical trials.gov identifier: NCT01189981.

    2006-07-01

    This final report published by the Swiss Federal Office of Energy (SFOE) presents a review of possible systems that could be used to promote power production in Switzerland using renewable energy sources. Promotional models on both the provider and consumer sides that use both price and quantity as control factors are examined. Three models are compared: the submission-to-tender model, the quota model with certificates and a model that uses cost-based feed-in tariffs. On the basis of a comparison with Austria, interaction between increasing the proportion of renewable forms of energy and the realisation of energy-efficiency goals is discussed. A further part of the report deals with various options for the use of biomass as a source of energy.

    Activities of the United States Energy Association were reviewed, as well as the manner in which its members are benefitting from the Association's programs. The principal cooperative program set up is the Utility Partnership Program, which was described. Through this program the Association is matching US companies, both electric utilities and gas utilities, with counterparts in Eastern Europe or the former Soviet Union. So far, about 25 partnerships were signed, e.g. in the Czech Republic, in Kazakhstan, in Poland, and in Slovakia. It was estimated that the return to the United States from the investments made by the American government in these Utility Partnership Programs has been well over 100-fold

    In the last fifteen years, Europe has been involved in the major development of photovoltaic (PV) solar energy. The Kyoto Protocol requirements and the European Union (EU) directives to promote the use of renewable energy sources (RES) together with environmental policies introduced for the development and use of alternative energies have generated a large number of market opportunities for this sector. Differences in the application of energy policies have caused significant imbalances in electricity systems and distortion of electricity prices. The main concern of governments is to define the support schemes to be used and how to combine them in the most profitable manner. The aim of this paper is to provide a comparative cost-effectiveness assessment using feed-in tariffs (FiT) and net-metering (NM) schemes in some representative EU countries. The authors have developed an economic model to evaluate the profitability of PV projects combining these support schemes. Results show not only the circumstances under which solar energy is economically profitable, but also the kind of PV systems, locations, minimum levels of tariff prices and specific combination of support schemes that should be promoted. - Highlights: • Comparative cost-effectiveness assessment combining FiT and NM support schemes. • A minimum FiT is proposed in addition to traditional financial performance indicators. • Results show the specific combinations of support schemes that should be promoted. • This work can aid efficient energy policy making. • Model could be applied to other types of RES projects and other geographical areas.

    Investment risks of utility-scale PV systems may arise from a wide range of sources: political stability in a region, interest rate levels and currency exchange rates or future energy price. However, the presence of stable political and economic conditions and feed-in tariffs or power purchase agreements may limit interest and price risks to acceptable levels. The technical risk of deviations between expected and actual life-time energy yield of a PV power plant is mostly influenced by the qu...

    The production of biogas through the anaerobic digestion of cattle manure and its subsequent use in the generation of electricity on larger farms in Ontario is currently economically attractive. This is a result of the Ontario Feed-In Tariff (FIT) program, which provides incentivized rates for the production of electricity from biogas. Although larger farms can take advantage of the higher rates for electricity, there are substantially more smaller farms for which individually designed and engineered biogas systems would be prohibitively expensive. By employing the concept of modular biogas plants, this analysis evaluates the economics of small-scale biogas utilization systems. Dairy farms with at least 33 animals and beef farms with at least 78 animals can operate economically attractive biogas systems. This analysis shows that approximately 9000 additional Ontario cattle farms would be able to take advantage of the FIT program, which would add 120 MW e of renewable energy capacity to the Ontario electrical grid.

    Griffes, P.H.

    1990-01-01

    This paper discusses portfolio analysis as a method to evaluate utility supply decisions. Specifically a utility is assumed to increase the value of its portfolio of assets whenever it invests in a new supply technology. This increase in value occurs because the new asset either enhances the return or diversifies the risks of the firm's portfolio of assets. This evaluation method is applied to two supply innovations in the electric utility industry: jointly-owned generating plants and supply contracts with independent power producers (IPPs)

    2016-09-20

    Many intervention-based studies aiming to improve mental health do not include a multi-attribute utility instrument (MAUI) that produces quality-adjusted life-years (QALYs) and it limits the applicability of the health economic analyses. This study aims to develop 'crosswalk' transformation algorithm between a measure for psychological distress General Health Questionnaire (GHQ-12) and MAUI EuroQoL (EQ-5D-3L). The study is based on a survey questionnaire sent to a random sample in four counties in Sweden in 2012. The survey included GHQ-12 and EQ-5D instruments, as well as a question about self-rated health. The EQ-5D index was calculated using the UK and the Swedish tariff values. Two OLS models were used to estimate the EQ-5D health state values using the GHQ-12 as exposure, based on the respondents (n = 17, 101) of two counties. The algorithms were applied to the data from two other counties, (n = 15, 447) to check the predictive capacity of the models. The final models included gender, age, self-rated health and GHQ-12 scores as a quantitative variable. The regression equations explained 40 % (UK tariff) and 46 % (Swedish tariff) of the variances. The model showed a satisfying predictive capacity between the observed and the predicted EQ-5D index score, with Pearson correlation = 0.65 and 0.69 for the UK and Swedish models, respectively. The algorithms developed in this study can be used to determine cost-effectiveness of services or interventions that use GHQ-12 as a primary outcome where the utility measures are not collected.

    This report describes work done and results obtained during performance of Task 1 of a study of Utility Requirements and Criteria for Fusion Options. The work consisted of developing a list of utility requirements for fusion optics containing definition of the requirements and showing their relative importance to the utility industry. The project team members developed a preliminary list which was refined by discussions and literature searches. The refined list was recast as a questionnaire which was sent to a substantial portion of the utility industry in this country. Forty-three questionnaire recipients responded including thirty-two utilities. A workshop was held to develop a revised requirements list using the survey responses as a major input. The list prepared by the workshop was further refined by a panel consisting of vice presidents of the three project team firms. The results of the study indicate that in addition to considering the cost of energy for a power plant, utilities consider twenty-three other requirements. Four of the requirements were judged to be vital to plant acceptability: Plant Capital Cost, Financial Liability, Plant Safety and Licensability

    2015-06-01

    Full Text Available Efficiency improvement is one of three patterns a public utility should follow in order to get funds for investments realization. The other two are recourse to bank loans or to private equity and tariff increase. Efficiency can be improved, for example, by growth and vertical integration and may be conditioned by environmental variables, such as customer and output density. Prior studies into the effects of these variables on the efficiency of water utilities do not agree on certain points (e.g., scale and economies of scope and rarely consider others (e.g., density economies. This article aims to contribute to the literature by analysing the efficiency of water utilities in Denmark, observing the effects of operational and environmental variables. The method is based on two-stage Data Envelopment Analysis (DEA applied to 101 water utilities. We found that the efficiency of the water sector was not affected by the observed variables, whereas that of wastewater was improved by smaller firm size, vertical integration strategy, and higher population density.

  18. Design of variable energy and price components of electricity tariffs as an incentive for system-efficient energy management of flexible consumers in households; Design variabler Energie- und Leistungspreiskomponenten von Stromtarifen als Anreiz fuer ein systemdienliches Energiemanagement flexibler Verbraucher in Haushalten

    2017-11-01

    To mitigate anthropogenic climate change, both the heating and transport sectors will need to be electrically driven, with the higher electrical demand met by emission-free technologies, in addition to general efficiency improvements. On the generation side, wind and photovoltaic power plants must have a rated power significantly exceeding the current peak demand, in order to cover this increased electrical requirement. On the consumption side, heat pumps and private electric vehicles will increase the percentage of energy withdrawn at the low-voltage level of the new system. Given the right incentives, these customers will shift the energy demand in such a way as to benefit the system. This flexibility can be used as a tool to deal with variable renewable insertion while avoiding simultaneous overloading of the power grid. This thesis analyses and evaluates the effects of different electricity tariff designs on energy consumption. These tariffs should incentivise households to adapt their energy consumption to market prices, without inducing critical peak demands in times of particularly low prices. Therefore, time-varying energy price components and power price components are combined into flexible electricity tariffs and implemented as target functions within an optimization problem. The cost-minimizing effect of household energy management is determined under these flexible tariffs, and the effects of the tariff designs on energy consumption and the induced costs are evaluated. Additionally, the results of the flexible tariff approach are compared with results from a centralized optimization by a virtual power plant. It is possible to develop a design for a suitable flexible tariff that decreases the energy procurement costs of electric vehicles while simultaneously reducing peak demand in comparison to a single real-time pricing incentive. Furthermore, this thesis shows that certain kinds of electricity tariff design do not only fail to support but actually

    This report aims at filling up some gaps in the French legislation relative to the determination of electricity and natural gas regulated tariffs and to the beneficiaries of these tariffs. It makes a synthesis of four proposals of law dealing with: the possibility for end-users and small companies to benefit again of the regulated electricity prices (proposals no 369 and 149), the permission of reversibility in the exercise of the rights relative to the eligibility for the purchase of electric power (proposal no 427), and the preservation of households' purchasing power by keeping up the regulated prices of electricity and natural gas (proposal no 462). The different articles are examined and some amendments are proposed by the commission. (J.S.)

    This text is the conclusion of a long parliamentary procedure with several debates about electricity and natural gas prices, for both individual users and companies. The first article of the proposal of law relative to regulated electricity and gas tariffs, is the only one that remains to be discussed, and concerns the households and the companies with a low power consumption. Examined first at the Senate on October 1, 2007, this proposal of law was debated at the House of Commons on December 11, 2007 and modified for one important point: the possibility for households who have made the choice of a de-regulated energy supplier to change back and benefit again of the regulated tariffs. The adoption of this amendment has led to make some adjustments in the proposal of law which are presented in this document. (J.S.)

    1982-01-01

    Though the biggest impact on a utility of nuclear power plant decommissioning may occur many years from now, procrastination of efforts to be prepared for that time is unwarranted. Foresight put into action through planning can significantly affect that impact. Financial planning can assure the recovery of decommissioning costs in a manner equitable to customers. Decision-making planning can minimize adverse affects of current decisions on later decommissioning impacts and prepare a utility to be equipped to make later decommissioning decisions. Technological knowledge base planning can support all other planning aspects for decommissioning and prepare a utility for decommissioning decisions. Informed project planning can ward off potentially significant pitfalls during decommissioning and optimize the effectiveness of the actual decommissioning efforts

    An important task in governing health services is to control costs. The literatures on both costcontainment and supplier induced demand focus on the effects of economic incentives on health care costs, but insights from these literatures have never been integrated. This paper asks how economic cost...... containment measures affect the utilization of health services, and how these measures interact with the number of patients per provider. Based on very valid register data, this is investigated for 9.556 Danish physiotherapists between 2001 and 2008. We find that higher (relative) fees for a given service...... are important, but that economics cannot alone explain the differences in health care utilization....

    Full Text Available  The aim of this article is to determine the potential trade effects of Transatlantic Trade and Investment Partnership (TTIP for the EU agri-food sector. The ex post analysis covered the characteristics of agri-food trade between the EU and the US in the years 2004–2014 on the basis of statistical data from the database of the World Bank WITS. The ex ante evaluation was carried out using SMART – a partial equilibrium model. The results of the study indicate that although bilateral agri-food trade relations of the EU–US have relatively little importance, but it is significant at the individual industries level. TTIP agreement, which includes the reduction of tariff barriers to agri-food trade between the EU and the US, will contribute to boosting bilateral agri-food trade to a greater extent for the US. The creation of a free trade produces mostly creation effect, whereby it will be asymmetric – concentrated in a few product groups.

    Among the regulatory policies, feed-in tariffs (FIT) and renewable portfolio standards (RPS) are the most popular to promote the development of renewable energy power industry. They can significantly contribute to the expansion of domestic industrial activities in terms of sustainable energy. This paper uses system dynamics (SD) to establish models of long-term development of China's waste incineration power industry under FIT and RPS schemes, and provides a case study by using scenario analysis method. The model, on the one hand, not only clearly shows the complex logical relationship between the factors but also assesses policy effects of the two policy tools in the development of the industry. On the other hand, it provides a reference for scholars to study similar problems in different countries, thereby facilitating an understanding of waste incineration power's long-term sustainable development pattern under FIT and RPS schemes, and helping to provide references for policy-making institutions. The results show that in the perfect competitive market, the implementation of RPS can promote long-term and rapid development of China's waste incineration power industry given the constraints and actions of the mechanisms of RPS quota proportion, the TGC valid period, and fines, compared with FIT. At the end of the paper, policy implications are offered as references for the government. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2012-11-15

    As a Global Environment Facility (GEF) founding implementing agency, UNDP has worked on over 230 GEF-supported clean energy projects in close to 100 developing countries since 1992. About 100 of these projects in 80 countries have focused on renewable energy, supported by approximately US $ 293 million in GEF funds and leveraging US $1.48 billion in associated co-financing from national governments, international organizations, the private sector and non-governmental organizations. As part of UNDP efforts to codify and share lessons learnt from these initiatives, this report addresses how scarce public resources can be used to catalyze larger private financial flows for renewable energy. It provides an overview of UNDP-GEF’s extensive work supporting development of national renewable energy policies such as feed-in tariffs. In these activities UNDP-GEF assists developing countries to assess key risks and barriers to technology diffusion and then to identify a mix of policy and financial de-risking measures to remove these barriers and drive investment. This approach is illustrated through three case studies in Uruguay, Mauritius and Kazakhstan. This report is complemented by a companion publication presenting an innovative UNDP financial modeling tool to assist policymakers in appraising different public instruments to promote clean energy.

    After a recall of the context and objectives of the analysis performed by the French Commission for Energy Regulation (CRE), and a synthetic presentation of the main conclusions, this report first proposes an assessment for 2015 by discussing the share of consumptions provided under the regulated tariff with respect to those provided on the retail market, the evolution of these tariffs, by noticing that ENGIE costs have been covered by income associated with sales at regulated tariffs. The second part addresses perspectives of evolution for supply costs by outlining the existence of market indexing, the lack of factors which would justify an evolution of gas price indexing level, and a possible reviewing of indices at the moment of revision of the indexing formula. The third part addresses the perspectives of evolution of non-supply related costs. It notices the impact of recent evolution of infrastructure costs, some lack of information regarding provisional trade costs, and a significant decrease of these costs for 2016

    Full Text Available Abstract Background Transnational tobacco companies (TTCs may respond to processes of regional trade integration both by acting politically to influence policy and by reorganising their own operations. The Central American Common Market (CACM was reinvigorated in the 1990s, reflecting processes of regional trade liberalisation in Latin America and globally. This study aimed to ascertain how British American Tobacco (BAT, which dominated the markets of the CACM, sought to influence policy towards it by member country governments and how the CACM process impacted upon BAT's operations. Methods The study analysed internal tobacco industry documents released as a result of litigation in the US and available from the online Legacy Tobacco Documents Library at http://legacy.library.ucsf.edu/. Documents were retrieved by searching the BAT collection using key terms in an iterative process. Analysis was based on an interpretive approach involving a process of attempting to understand the meanings of individual documents and relating these to other documents in the set, identifying the central themes of documents and clusters of documents, contextualising the documentary data, and choosing representative material in order to present findings. Results Utilising its multinational character, BAT was able to act in a coordinated way across the member countries of the CACM to influence tariffs and taxes to its advantage. Documents demonstrate a high degree of access to governments and officials. The company conducted a coordinated, and largely successful, attempt to keep external tariff rates for cigarettes high and to reduce external tariffs for key inputs, whilst also influencing the harmonisation of excise taxes between countries. Protected by these high external tariffs, it reorganised its own operations to take advantage of regional economies of scale. In direct contradiction to arguments presented to CACM governments that affording the tobacco industry

    Full Text Available Abstract Background The use of patient reported outcome measures within cost-effectiveness analysis has become commonplace. However, specific measures are required that produce values, referred to as 'utilities', that are capable of generating quality adjusted life years. One such measure - the EQ-5D - has come under criticism due to the inherent limitations of its three-level response scales. In evaluations of chronic pain, the numerical pain rating scale (NPRS which has eleven levels is routinely used which has a greater measurement range, but which can not be used in cost-effetiveness analyses. This study derived utility values for a series of EQ-5D health states that replace the pain dimensions with the NPRS, thereby allowing a potentially greater range of pain intensities to be captured and included in economic analyses. Methods Interviews were undertaken with 100 member of the general population. Health state valuations were elicited using the time trade-off approach with a ten year time horizon. Additionally, respondents were asked where the EQ-5D response scale descriptors of moderate and extreme pain lay on the 11-point NPRS scale. Results 625 valuations were undertaken across the study sample with the crude mean health state utilities showing a negative non-linear relationship with respect to increasing pain intensity. Relative to a NPRS of zero (NPRS0, the successive pain levels (NPRS1-10 had mean decrements in utility of 0.034, 0.043, 0.061, 0.121, 0.144, 0.252, 0.404, 0.575, 0.771 and 0.793, respectively. When respondents were asked to mark on the NPRS scale the EQ-5D pain descriptors of moderate and extreme pain, the median responses were '4' and '8', respectively. Conclusions These results demonstrate the potential floor effect of the EQ-5D with respect to pain and provide estimates of health reduction associated with pain intensity described by the NPRS. These estimates are in excess of the decrements produced by an application

    Direct regulation of public utility activity and behavior has been the predominant approach to protect the public interest in this country. Changes in technology, as well as new thinking about the optimum role of regulation, have created a changing atmosphere in all of the traditional public utility industries. Competitive markets for many of the products and services in these industries have been developing. While monopoly power will continue to exist in certain parts of these industries and require direct regulation, in many areas a growing reliance upon competition as the best method of serving the public interest is developing. With this shift in emphasis from regulation to free markets, the antitrust laws take on new importance for these industries. In the absence of direct regulator control, those laws are society`s primary method of insuring the markets necessary to make competition an effective device for protecting the public interest. This study provides an overview of the antitrust laws, briefly describes the applicable theoretical underpinnings, and then turns to areas where public utility activity may pose special problems or conflicts with prevailing antitrust policy.

    This paper demonstrates that with careful analysis of ash from multiple biomass and waste wood fired power plants that most of the ash can serve a useful purpose. Some applications require higher levels of consistency than others. Examples of ash spreading for agricultural purposes as a lime supplement for soil enhancement in Maine and North Carolina, as well as a roadbase material in Maine are discussed. Use of ash as a horticultural additive is explored, as well as in composting as a filtering media and as cover material for landfills. The ash utilization is evaluated in a framework of environmental responsibility, regulations, handling and cost. Depending on the chemical and physical properties of the biomass derived fly ash and bottom ash, it can be used in one or more applications. Developing a program that utilizes ash produced in biomass facilities is environmentally and socially sound and can be financially attractive.

    The effects of the National Energy Act on the use of coal in US industrial and utility power plants are considered. Innovative methods of using coal in an environmentally acceptable way are discussed: furnace types, fluidized-bed combustion, coal-oil-mixtures, coal firing in kilns and combustion of synthetic gas and liquid fuels. Fuel use in various industries is discussed with trends brought about by uncertain availability and price of natural gas and fuel oils: steel, chemical, cement, pulp and paper, glass and bricks. The symposium on Industrial Coal Utilization was sponsored by the US DOE, Pittsburgh Energy Technology Center, April 3 to 4, 1979. Twenty-one papers have been entered individually into the EDB.

    About 200 research reactors are now in operation in different parts of the world, and at least 70 such facilities, which are in advanced stages of planning and construction, should be critical within the next two or three years. In the process of this development a multitude of problems are being encountered in formulating and carrying out programs for the proper utilization of these facilities, especially in countries which have just begun or are starting their atomic energy work. An opportunity for scientific personnel from different Member States to discuss research reactor problems was given at an international symposium on the Programing and Utilization of Research Reactors organized by the Agency almost immediately after the General Conference session. Two hundred scientists from 35 countries, as well as from the European Nuclear Energy Agency and EURATOM, attended the meeting which was held in Vienna from 16 to 21 October 1961

    Customer issues affected by the restructuring of the $250 billion US electric power industry were discussed. In the past the industry's vertically integrated utilities conducted their business in protected geographic markets. With deregulation and greater competition, that industry structure will change. This presentation highlighted the strategies that Unicom is using to react to the restructuring of the electric power industry. The underlying principle is for the utility to reinvent itself to change its market orientation and focus on customer services, such as reliability, responsiveness, custom tailored solutions, and guaranteed savings over time. Attempting to become total energy providers and delivering integrated solutions to meet the needs of large industrial and commercial consumers, intensive market research, improved service and installation, and sophisticated customer retention initiatives will also have to be high on the agenda

    Full Text Available After using simplified Labanotation as a didactic tool for some years, the author can conclude that it accomplishes at least three main functions: efficiency of rehearsing time, social recognition and broadening of the choreographic consciousness of the dancer. The doubts of the dancing community about the issue of ‘to write or not to write’ are highly determined by the contexts and their own choreographic evolution, but the utility of Labanotation, as a tool for knowledge, is undeniable.
