Book Synopsis Cournot Competition in Wholesale Electricity Markets by : Erik Lundin
Download or read book Cournot Competition in Wholesale Electricity Markets written by Erik Lundin and published by . This book was released on 2017 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal shifts in bid curves observed in wholesale electricity markets are consistent with Cournot competition. Quantity competition reduces the informational requirements associated with evaluating market performance because the markups of all producers then depend on the same inverse residual demand curve instead of one for each firm. We apply the model to the day-ahead market of the Nordic power exchange, Nord Pool, for the years 2011-2013. Results suggest that mark-ups were 8-11 percent. We find some support for the hypothesis that the division of Sweden into price areas in 2011 increased the exercise of market power.
Book Synopsis Vertical Arrangements, Market Structure, and Competition by : James B. Bushnell
Download or read book Vertical Arrangements, Market Structure, and Competition written by James B. Bushnell and published by . This book was released on 2007 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines vertical arrangements in electricity markets. Vertically integrated wholesalers, or those with long-term contracts, have less incentive to raise wholesale prices when retail prices are determined beforehand. For three restructured markets, we simulate prices that define bounds on static oligopoly equilibria. Our findings suggest that vertical arrangements dramatically affect estimated market outcomes. Had regulators impeded vertical arrangements (as in California), our simulations imply vastly higher prices than observed and production inefficiencies costing over 45 percent of those production costs with vertical arrangements. We conclude that horizontal market structure accurately predicts market performance only when accounting for vertical structure.

Book Synopsis Electricity Reform in Europe by : Jean-Michel Glachant
Download or read book Electricity Reform in Europe written by Jean-Michel Glachant and published by Edward Elgar Publishing. This book was released on 2009-01-01 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: . . . this volume comes across as one of the most profound sources on the specifics of European electricity market restructuring. Competition and Regulation in Network Industries The SESSA study on the Internal Energy Market was an important and influential contribution towards the Commission s proposal for a third package of proposals, intending to bring more effective competition and better security of supply to Europe s energy markets. This volume, based on the results of the study is an important and welcome contribution to the ongoing debate on these proposals. Andris Piebalgs, Commissioner for Energy at the European Commission The chapters in this book are written by the leading European scholars who have studied the structure, behavior and performance of liberalised electricity markets in many European countries as well as in other regions of the world. Both the analyses and the policy recommendations contained in this volume are well worth careful consideration by policymakers in Europe, as well as by policymakers in other countries that are seeking to adopt successful electricity sector liberalisation programs. From the foreword by Paul L. Joskow, Massachusetts Institute of Technology, US Dynamism or dissipation? Competition or national champions? Will enlargement promote or delay reform? Energy economists contemplate the challenges posed by the restless and discontent European Commission. Stephen Littlechild, University of Birmingham and Judge Institute for Management Studies, University of Cambridge, UK The challenge of European electricity reform is being met, although gradually, delays notwithstanding. This book provides precious help in spotting where the necessary further efforts should be directed. In the US mistakes and delays have occurred, no less than in Europe, but an aggressive federal regulator (absent in Europe) is working to overcome them. Electricity markets do not happen, they have to be built. Here are suggestions for a workable European market design. No ideology, just competence and wisdom from both theory and experience. Will Europe learn? Pippo Ranci, Università Cattolica del Sacro Cuore, Italy The realisation of a European internal market for energy is still a work in progress. Written by leading European scholars and discussed with major energy stakeholders, this book presents a thorough analysis of the motives and methods needed to achieve a single European energy market. The authors discuss the critical issues surrounding an internal European energy market including: market design, competition and market power, sustainable energy versus the market, regulation and harmonisation, benchmarking and indicators, modelling of competition, market prices and energy forecasts. They provide a multi-disciplinary assessment of the best way to build the market base of a future European energy policy. Electricity Reform in Europe will be of great interest to decision makers and managers in the energy industry or business sector as they will be able to see the whole European energy policy picture beyond their own corporate interests. The book will also appeal to national and European energy administrations, regulatory bodies and policy makers providing a synthesis of all relevant policy issues.

Book Synopsis Competitive Equilibrium in the Italian Wholesale Electricity Market by : Simona Bigerna
Download or read book Competitive Equilibrium in the Italian Wholesale Electricity Market written by Simona Bigerna and published by . This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The market power analysis in electricity market is relevant for understanding the competitive development of the industry's restructuring and the liberalization process. The paper analyzes the market power exercised by power generators in the Italian wholesale electricity market. Following the approach of Wolak (2003, 2009), the extent of market power is measured using the Lerner index computed as the inverse of arc elasticity of the residual demand faced by each Cournot competitors. Then, the market supply curves have been adjusted to entail market power effects and the new market resolutions were derived. The new equilibrium prices are the competitive ones and represent the market clearing price that would have been if the electricity market was competitive and the effects of unilateral market power were removed.
Book Synopsis Short-Term Forward and Spot Prices in Organized Wholesale Electricity Markets by : Jeremy Larrieu
Download or read book Short-Term Forward and Spot Prices in Organized Wholesale Electricity Markets written by Jeremy Larrieu and published by . This book was released on 2016 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern organized wholesale electricity markets, power is sold competitively in a two-settlement auction comprised of a short-term forward (or "day-ahead") market with elastic demand, and a spot (or "real-time") imbalance market characterized by an inelastic residual demand curve - a construct that the literature on the subject tends to ignore. To understand the strategic behavior of firms looking maximize joint profits over both markets, I construct a two-settlement model of electricity prices in which firms compete to meet demand from consumers, first in quantities, then in prices. I show that the ensuing forward premium depends on the costliness of spot commitment relative to firms' ability to exercise market power by setting quantities in the forward market. Using hourly data from the California Independent System Operator, I find that the model helps explain price formation in the California market, and that the forward market solutions are close to the Cournot outcome due to the relative insensitivity of the spot equilibrium price to individual firm's forward commitment decisions.
Book Synopsis Economic Interactions Between Electricity Reserve Markets and Wholesale Electricity Markets by : Lars Wieschhaus
Download or read book Economic Interactions Between Electricity Reserve Markets and Wholesale Electricity Markets written by Lars Wieschhaus and published by . This book was released on 2008 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes the interdependence of reserve and spot markets for electricity applying equilibrium models. We develop a Cournot model to analyze the impact of different pricing mechanisms at the reserve market (uniform and pay-as-bid) on spot market prices. Furthermore, we show how the demand requirement for reserve capacities can drive prices in the spot market. The models are tested using a dataset of the German electricity market. One result is that a more competitive reserve market helps to keep prices on the spot market low.
Book Synopsis Modelling Prices in Competitive Electricity Markets by : Derek W. Bunn
Download or read book Modelling Prices in Competitive Electricity Markets written by Derek W. Bunn and published by John Wiley & Sons. This book was released on 2004-04-02 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity markets are structurally different to other commodities, and the real-time dynamic balancing of the electricity network involves many external factors. Because of this, it is not a simple matter to transfer conventional models of financial time series analysis to wholesale electricity prices. The rationale for this compilation of chapters from international authors is, therefore, to provide econometric analysis of wholesale power markets around the world, to give greater understanding of their particular characteristics, and to assess the applicability of various methods of price modelling. Researchers and professionals in this sector will find the book an invaluable guide to the most important state-of-the-art modelling techniques which are converging to define the special approaches necessary for unravelling and forecasting the behaviour of electricity prices. It is a high-quality synthesis of the work of financial engineering, industrial economics and power systems analysis, as they relate to the behaviour of competitive electricity markets.
Book Synopsis Competition, Contracts and Electricity Markets by : Jean-Michel Glachant
Download or read book Competition, Contracts and Electricity Markets written by Jean-Michel Glachant and published by Edward Elgar Publishing. This book was released on 2011 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book fills a gap in the existing literature by dealing with several issues linked to long-term contracts and the efficiency of electricity markets. These include the impact of long-term contracts and vertical integration on effective competition, generation investment in risky markets, and the challenges for competition policy principles. On the one hand, long-term contracts may contribute to lasting generation capability by allowing for a more efficient allocation of risk. On the other hand, they can create conditions for imperfect competition and thus impair short-term efficiency. The contributors – prominent academics and policy experts with inter-disciplinary perspectives – develop fresh theoretical and practical insights on this important concern for current electricity markets. This highly accessible book will strongly appeal to both academic and professional audiences including scholars of industrial, organizational and public sector economics, and competition and antitrust law. It will also be of value to regulatory and antitrust authorities, governmental policymakers, and consultants in electricity law and economics.

Book Synopsis Electricity Deregulation by : James M. Griffin
Download or read book Electricity Deregulation written by James M. Griffin and published by University of Chicago Press. This book was released on 2009-11-15 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electricity market has experienced enormous setbacks in delivering on the promise of deregulation. In theory, deregulating the electricity market would increase the efficiency of the industry by producing electricity at lower costs and passing those cost savings on to customers. As Electricity Deregulation shows, successful deregulation is possible, although it is by no means a hands-off process—in fact, it requires a substantial amount of design and regulatory oversight. This collection brings together leading experts from academia, government, and big business to discuss the lessons learned from experiences such as California's market meltdown as well as the ill-conceived policy choices that contributed to those failures. More importantly, the essays that comprise Electricity Deregulation offer a number of innovative prescriptions for the successful design of deregulated electricity markets. Written with economists and professionals associated with each of the network industries in mind, this comprehensive volume provides a timely and astute deliberation on the many risks and rewards of electricity deregulation.
Book Synopsis Understanding Competitive Pricing and Market Power in Wholesale Electricity Markets by : Severin Borenstein
Download or read book Understanding Competitive Pricing and Market Power in Wholesale Electricity Markets written by Severin Borenstein and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discussions of competition in restructured electricity markets have revealed many misunderstandings about the definition, diagnosis, and implications of market power. In this paper, I attempt to clarify the meaning of market power and show how it can be distinguished from competitive pricing in markets with significant short-run supply constraints. I also address two common myths about market power: (a) that it is present in all markets and (b) that it must be present in order for firms to remain profitable in markets with significant fixed costs. I conclude by arguing that, while a finding of market power in an industry does not necessarily indicate that government intervention is warranted, such analysis is an important part of creating sound public policy.
Book Synopsis Measuring Demand Responses to Wholesale Electricity Prices Using Market Power Indices by : Talat Genc
Download or read book Measuring Demand Responses to Wholesale Electricity Prices Using Market Power Indices written by Talat Genc and published by . This book was released on 2016 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate wholesale demand response to hourly price movements in the Ontario wholesale electricity market using detailed generator and market level data. We calculate hourly market power measures such as the Lerner Index and the Residual Supplier Index, which are utilized in a Cournot competition model to structurally estimate price elasticity of demand during peak hours of days, seasons and years. We find that price elasticities are small and statistically significant, and they exhibit large variations over the times of days/seasons and show differences over the years. For instance, while the elasticity estimates fall into the range [-0.021, -0.133] in 2007, they are in the interval of [-0.013, -0.053] in 2008. We also extend the study period to include 2006 (during which extreme weather conditions occurred) and 2009 (when the economic crisis hit and natural gas prices plummeted) to measure the demand responses to irregular price movements and find that price elasticities during the economic crisis were higher than a year earlier. Comparing high demand winter hours to high demand summer hours indicates that consumers' price responsiveness is lower in summer than in winter during 2006-2009. Moreover, we employ these indices along with the estimated price elasticities to project the likely impact of interconnection capacity expansions on market prices. Our calibrations show that even a small amount of transmission investment (and hence trade activity) can result in substantial market price reductions. In addition, we discuss how our approach could be used to estimate price elasticities for other goods such as crude oil and gasoline.
Book Synopsis Capacity Withdrawals in the Electricity Wholesale Market by : Panagiotis Tsangaris
Download or read book Capacity Withdrawals in the Electricity Wholesale Market written by Panagiotis Tsangaris and published by Springer. This book was released on 2017-08-30 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the issue of capacity withdrawals in the electricity wholesale market. Electricity generators can exercise market power in the wholesale market either by withdrawing generation capacity, or by pricing above competitive levels in order to achieve a higher market price and, thereby, increase revenues. After a comprehensive explanation of capacity withdrawal practices and the issues that arise when proceeding under competition law, the book analyses whether an increased state of transparency, as provided for in the REMIT and Regulation 543/2013, could facilitate the efficient functioning of electricity wholesale markets and the investigation of capacity withdrawal practices. It also examines the effect of the prohibition of market manipulation as prescribed in the REMIT in dealing with abusive capacity withdrawals in the electricity wholesale market.
