Available in PDF, EPUB and Kindle. Book excerpt: Restructuring electricity markets has enabled wholesalers to exercise market power. Using a common method of measuring competitive behavior in these markets, several studies have found substantial inefficiencies. This method overstates actual welfare loss by ignoring production constraints that result in non-convex costs. I develop an alternative method that accounts for these constraints and apply it to the Pennsylvania, New Jersey, and Maryland market. For the summer following restructuring, the common method implies that market imperfections resulted in considerable welfare loss, with actual production costs exceeding the competitive model's estimates by 13 to 21 percent. In contrast, my method finds that actual costs were only between three and eight percent above the competitive levels. In particular, it is the fringe firms whose costs increase, while strategic firms reduce production and costs.

Available in PDF, EPUB and Kindle. Book excerpt: Unlike other studies that have found substantial inefficiencies in restructured electricity markets, this paper provides estimates that reveal relatively competitive behavior in the Pennsylvania, New Jersey, and Maryland market. This distinctive conclusion results from using a model that incorporates structural market features and particular production constraints that are not captured in previous studies. First, the vertical integration of firms in the PJM market reduces electricity producers' interest in setting high prices; producers sell wholesale electricity and also are required to buy power, which they provide to their retail customers at set rates. My model reflects this degree of vertical integration of PJM firms. Second, I account for production constraints that result in cost nonconvexities. Measures of price-cost margins based on a commonly used method that does not incorporate these nonconvexities imply that market imperfections during the summer following PJM's restructuring increased procurement costs 51% ($950 million). That method further implies considerable welfare loss as actual production costs exceeded the competitive model's estimates by 12.5%. This paper develops a consistent estimate of competitive production decisions that respect important production constraints, and it presents estimates showing that costs were only 3.4% above competitive levels. Using this new method of estimating production, I compare behavior of two producers that have relatively few retail customers with other firms. Consistent with these vertically integrated firms' incentives, only firms with large net selling positions in the market reduced output relative to competitive production estimates.
Download or read book Measuring the Trilemma in Electricity Markets with Respect to Market Openness in OECD Countries written by Shai Hassid and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work aims to observe whether OECD countries with more open electricity markets also experience better performing electricity markets. The performance of electricity markets is measured using a composite index which is developed throughout the dissertation and is based on three domains: economic, environmental and supply (the 'trilemma'). The index results show a trade-off between the economic domain, in particular low electricity prices, and the environmental and supply domains in countries with low performing electricity markets. The comparison of the developed index and the OECD index, which measures the openness of electricity markets, yields inconclusive results which suggest a weak link between market openness and performance. On the other hand, the comparison of the electricity performance index with an index that measures quality of institutions shows a more robust link between quality of institutions and electricity market performance, suggesting that quality of institutions play a stronger role in balancing the trilemma than market openness. Furthermore, the openness of electricity market and institutional quality indices together provide more robust results when compared to the electricity markets performance index, implying that institutional quality might be vital for the operation of open electricity markets. The relationship between performance of electricity markets and their openness and institutional quality should be further explored using time series data and a more extensive set of indicators to measure the performance of electricity markets and institutional quality specific to electricity markets.

Book excerpt: French Abstract: Mesurer le pouvoir de marché et les inefficacités du marché restructuré pour l'électricité en Alberta: un design de marché pour l'énergie seulement. Les auteurs mesurent le degré de pouvoir de marché effectif en acte et les inefficacités du marché restructuré de l'électricité en Alberta. Utilisant les données par heure sur le marché en gros, on découvre que les firmes exercent un pouvoir de marché substantiel dans les plages horaires de forte demande où il y a excès de capacité de production limité. L'exercice du pouvoir de marché est faible dans les autres plages horaires. Les inefficacités sont plus grandes dans les heures de grande demande et soulèvent les coûts de production de 6,7 % à 19 % au-dessus des coûts concurrentiels de référence - en moyenne de 13 %. Cela se traduit par une augmentation de 2,1% du prix moyen par heure quand c'est reporté sur toutes les heures. Un cadre de réglementation récent a clarifié que certains types d'usage de pouvoir de marché sont permis en Alberta. Les auteurs ont observé que le comportement stratégique a changé après ces clarifications. L'exercice du pouvoir de marché s'est accru. On montre que les revenus observés sont souvent suffisants pour promouvoir l'investissement dans des technologies fondées sur le gaz naturel. Les rentes tirées de l'usage du pouvoir de marché peuvent excéder les coûts estimés pour accroître la capacité dans certaines technologies de génération d'énergie. Cependant, on montre que les profits dans le marché de l'énergie en l'absence de l'usage du pouvoir de marché sont insuffisants pour promouvoir l'investissement dans le développement de capacité de génération additionnelle. Cela souligne l'importance de considérer à la fois les mesures à court et à long terme de la performance du marché pour l'électricité

Available in PDF, EPUB and Kindle. Book excerpt: The integration of national electricity systems into a single internal European electricity market is not progressing well with the result that the level of competition in the sector remains unsatisfactory. This had led to proposals to apply ex ante remedies that directly bear on the structure of national incumbents. These measures involve quantitative recommendations such as virtual auctioning of capacity or divestitures that increase the number of competing firms. The evaluation of these measures partly relies on computable oligopoly models of the restructured electricity sector. This paper analyses the recent literature of these models and concludes that they are not currently capable of providing the degree of legal and regulatory certainty that the importance of these ex ante remedies requires. The state of the art in these models is such that their results reflect more a set of non-testable assumptions than observed facts or unambiguous theory. More academic work is necessary before these models can be applied in a legal or regulatory context. The conclusion is that this work on the structure of national electricity market distracts from the fundamental objective to introduce competition in the power sector by integrating the national markets into a single electricity market.

Available in PDF, EPUB and Kindle. Book excerpt: After 2 decades, policymakers and regulators agree that electricity market reform, liberalization and privatization remains partly art. Moreover, the international experience suggests that in nearly all cases, initial market reform leads to unintended consequences or introduces new risks, which must be addressed in subsequent “reform of the reforms. Competitive Electricity Markets describes the evolution of the market reform process including a number of challenging issues such as infrastructure investment, resource adequacy, capacity and demand participation, market power, distributed generation, renewable energy and global climate change. Sequel to Electricity Market Reform: An International Perspective in the same series published in 2006 Contributions from renowned scholars and practitioners on significant electricity market design and implementation issues Covers timely topics on the evolution of electricity market liberalization worldwide

Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the relative importance of horizontal market structure, auction design, and vertical arrangements in explaining electricity prices. We define vertical arrangements as either vertical integration or long term contracts whereby retail prices are determined prior to wholesale prices. This is generally the case in electricity markets. These ex ante retail price commitments mean that a producer has effectively entered into a forward contract when it takes on retail customers. The integrated firm has less incentive to raise wholesale prices when its sale price is constrained. For three restructured wholesale electricity markets, we simulate two sets of prices that define the bounds on static oligopoly equilibria. Our findings suggest that vertical arrangements dramatically affect estimated market outcomes. Simulated prices that assume Cournot behavior but ignore this vertical scope vastly exceed observed prices. After accounting for the arrangements, performance is similar to Cournot in each market. Our results indicate that auction design has done little to limit strategic behavior and that horizontal market structure accurately predicts market performance only when vertical structure is also taken into account.

Available in PDF, EPUB and Kindle. Book excerpt: In the new deregulated competitive Italian electricity many interesting issues arise as the market complexity, the firm strategic behavior, the market power size, and so on. Effective competition in the electricity market is a necessary features of a successful supply industry restructuring. In this paper we examine the degree of competition in the Italian market during the period April 2004 to December 2004 in two principal ways. In the first one we estimate a very intuitive relation among the differences between the hourly equilibrium price (ph) and the individual hourly bids that the competitors offer around ph, and a large set of structural and behavioral variables. In the second one the aim is twofold. The first one is to build the residual demand for each Italian Generation Company. The construction of the residual demand curve system is the necessary condition to get the second aim which is to measure the unilateral market power for the Italian Generation Companies. Following Wolak (2003) approach the appropriate measure of the unilateral market power is the Lerner index based on the residual demand curve elasticity which is computed as arc elasticity. The expected results is a deeper understanding of the Wholesale Italian Electricity Markets and of its mechanism in order to enhance competition and to design appropriate market surveillance.

This book was released on 2001-10-31 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges facing participants in competitive electricity markets are staggering: high price volatility introduces significant financial risk into an industry accustomed to guaranteed rates of return, while illiquid forward markets prevent effective hedging strategies from being implemented. Valuation, Hedging and Speculation in Competitive Electricity Markets: A Fundamental Approach , examines the unique properties which separate electricity from other traded commodities, including the lack of economical storage, and the impact of a scarce transmission network. The authors trace the sources of uncertainties in the price of electricity to underlying physical and economic processes, and incorporate these into a bid-based model for electricity spot and forward prices. They also illustrate how insufficient market data can be circumvented by using a combination of price and load data in the marking- to-market process. The model is applied to three classes of problems central to the operation of any electric utility or power marketer; valuing generation assets, formulating dynamic hedging strategies for load serving obligations, and pricing transmission contracts and locational spread options. Emphasis is placed on the difference between trades which can be 'booked out' in the forward markets, and those which must be carried through to delivery. Lately, significant attention has been given to the role of regulators in mitigating excessive price levels in electricity markets. The authors conduct a quantitative analysis of the long-term effects of regulatory intervention through the use of price caps. By modeling the dynamic interplay between the observed price levels and the decision to invest in new generation assets, it is shown how such short term fixes can lead to long term deficits in the available generation capacity, and ultimately to market failures and blackouts.

Available in PDF, EPUB and Kindle. Book excerpt: The latest practical applications of electricity market equilibrium models in analyzing electricity markets Electricity market deregulation is driving the power energy production from a monopolistic structure into a competitive market environment. The development of electricity markets has necessitated the need to analyze market behavior and power. Restructured Electric Power Systems reviews the latest developments in electricity market equilibrium models and discusses the application of such models in the practical analysis and assessment of electricity markets. Drawing upon the extensive involvement in the research and industrial development of the leading experts in the subject area, the book starts by explaining the current developments of electrical power systems towards smart grids and then relates the operation and control technologies to the aspects in electricity markets. It explores: The problems of electricity market behavior and market power Mathematical programs with equilibrium constraints (MPEC) and equilibrium problems with equilibrium constraints (EPEC) Tools and techniques for solving the electricity market equilibrium problems Various electricity market equilibrium models State-of-the-art techniques for computing the electricity market equilibrium problems The application of electricity market equilibrium models in assessing the economic benefits of transmission expansions for market environments, forward and spot markets, short-term power system security, and analysis of reactive power impact Also featured are computational resources to allow readers to develop algorithms on their own, as well as future research directions in modeling and computational techniques in electricity market analysis. Restructured Electric Power Systems is an invaluable reference for electrical engineers and power system economists from power utilities and for professors, postgraduate students, and undergraduate students in electrical power engineering, as well as those responsible for the design, engineering, research, and development of competitive electricity markets and electricity market policy.
