This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenges currently facing particIpants m competitive electricity markets are unique and staggering: unprecedented price volatility, a crippling lack of historical market data on which to test new modeling approaches, and a continuously changing regulatory structure. Meeting these challenges will require the knowledge and experience of both the engineering and finance communities. Yet the two communities continue to largely ignore each other. The finance community believes that engineering models are too detailed and complex to be practically applicable in the fast changing market environment. Engineers counter that the finance models are merely statistical regressions, lacking the necessary structure to capture the true dynamic properties of complex power systems. While both views have merit, neither group has by themselves been able to produce effective tools for meeting industry challenges. The goal of this book is to convey the fundamental differences between electricity and other traded commodities, and the impact these differences have on valuation, hedging and operational decisions made by market participants. The optimization problems associated with these decisions are formulated in the context of the market realities of today's power industry, including a lack of liquidity on forward and options markets, limited availability of historical data, and constantly changing regulatory structures.

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.

Download or read book Vertical Integration in Restructured Electricity Markets written by Erin T. Mansur and published by . This book was released on 2003 with total page 0 pages. 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 Vertical Integration and Market Power in Electricity Markets written by Seamus Hogan and published by . This book was released on 2019 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical separation of generation from electricity retailing has often been required as a condition of electricity market liberalisation. A well-developed and liquid contracts market is similarly suggested as necessary to manage the resulting wholesale market risks, which risks are further exacerbated by competition. Such contracts markets are rare, however, and increasingly evidence is emerging that vertical integration is associated not just with improved wholesale market risk management, but also reduced wholesale market power. This paper develops a theoretical model showing that non-vertically integrated generators will over-report their inverse supply curves, with the incentive to over-report increasing with the firm's share of generating capacity. Conversely, in a vertically integrated industry, no over-reporting occurs when integrated firms have balanced shares in wholesale and retail markets. In general, firms whose share of generating capacity is higher (lower) than their retail market share will over-report (under-report) their inverse supply functions. Integration is found to affect retail electricity prices only via its effect on retail marginal costs. We find that retail prices are higher with vertical separation than with either balanced integration, or full integration without a wholesale market. These results suggest a re-evaluation of the importance of generator wholesale market power in vertically integrated electricity industries, and of measures to improve retail market competitiveness under either vertical integration or separation.

Download or read book Vertical Integration and the Restructuring of the U S Electricity Industry written by Robert J. Michaels and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Debates on restructuring of the U.S. electricity industry are often about the degree to which market relationships should replace transactions that formerly took place within regulated, vertically integrated utilities. Markets for the purchase of energy by vertically unintegrated distribution utilities are clearly feasible, but vertical deintegration of existing systems may entail foregoing some operational and reliability benefits that are important in light of electricity's unique characteristics. Research and policy on restructuring have almost totally disregarded a large econometric literature on the savings from vertical integration. At the same time, policy makers have accepted the results of flawed studies that purport to estimate the benefits of switching to a market regime. A review of California's restructuring history shows that vertical integration was viewed primarily as a tool that incumbent utilities might use to perpetuate their market power. The disregard of its benefits led to questionable divestitures that produced superficially competitive market structures, and to the institution of Independent System Operators whose costs have yet to be compared to their benefits.

Download or read book Electricity Deregulation and Vertical Integration written by Donald Burtt and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work examines the progression of generators and retailers, following electricity deregulation, to vertically integrate (VI) to determine whether all participants might benefit, or because generators are provided with increased market power, electricity consumers in particular could be worse off. The drivers of generators and retailers to vertically integrate are examined, with the lessons learnt applied to the Queensland electricity market. A literature review was first undertaken, with particular reference to the writings of Oliver Williamson. The Queensland analysis concluded that the maximum benefits that consumers could expect from VI was $138 million p.a. with current meter technology and strong retail competition, increasing to $156 million p.a. if meter technology improved. Total possible VI benefits were estimated at $321 million p.a., so consumers could expect to receive no more than 50% of total VI benefits. That is in a strongly competitive retail market, consumers could expect to receive, at the most, 50% of VI benefits, whereas in a weakly competitive retail market, consumers could be worse off.

Download or read book Vertical Integration and Capacity Competition in Electricity Markets written by Rowan Walshaw and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper characterises the impact of vertical integration on price equilibria and incentives to strategically withhold capacity in a wholesale electricity auction. A two-stage game is analysed where vertically integrated firms first declare the quantity of electricity available and then compete in a uniform price auction. Consistent with empirical literature on electricity markets, the model finds that firms' incentives are determined by their net demand position in the market. Results indicate that for the majority of parameter values, a vertically integrated structure yields a greater occurrence of competitive pricing in the wholesale market. Contrary to recent analysis of non-integration, vertical integration eliminates incentives for strategic capacity withholding.

Download or read book Electricity Derivatives written by René Aïd and published by Springer. This book was released on 2015-01-14 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offering a concise but complete survey of the common features of the microstructure of electricity markets, this book describes the state of the art in the different proposed electricity price models for pricing derivatives and in the numerical methods used to price and hedge the most prominent derivatives in electricity markets, namely power plants and swings. The mathematical content of the book has intentionally been made light in order to concentrate on the main subject matter, avoiding fastidious computations. Wherever possible, the models are illustrated by diagrams. The book should allow prospective researchers in the field of electricity derivatives to focus on the actual difficulties associated with the subject. It should also offer a brief but exhaustive overview of the latest techniques used by financial engineers in energy utilities and energy trading desks.

Download or read book From Regulation to Competition New frontiers in electricity markets written by Michael A. Einhorn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric utilities throughout the world continue to face new challenges involving ownership, market structure, and regulation. There are three related issues at hand. First, should ownership be private or public? Second, what operations should be integrated and where is competition feasible? Third, where is regulation necessary and can it be made more efficient? This volume bears directly upon these concerns. The book contains two sections. The first six articles discuss the British electricity experiment that has privatized and disintegrated the nation's generation, transmission, and distribution companies, introduced market competition for power purchases, and implemented incentive regulation for monopolized transmission and distribution grids. The remaining articles focus on the theater in which significant microeconomic issues will continue to emerge, most immediately in the U.K. and U.S.A. -- the coordination and pricing of transmission.

Download or read book Energy Hedging in Asia Market Structure and Trading Opportunities written by P. Fusaro and published by Springer. This book was released on 2005-08-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the latest developments in the Asia-Pacific community in terms of how deregulation and privatization are bringing more risk to energy companies. In the light of these market changes, interest in energy risk management has grown substantially and is becoming a fiduciary responsibility of energy companies. As energy trading, power exchanges and hedging techniques establish themselves in the oil, power and gas sectors, so then do newer derivatives markets emerge in LNG hedging, weather derivatives and freight hedging. Fusaro and James, as seasoned market practitioners in the region, focus on these market changes and examine the future of Asian energy hedging.

Download or read book Competitive Electricity Markets written by Fereidoon Sioshansi and published by Elsevier. This book was released on 2011-10-10 with total page 625 pages. 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

Download or read book Vertical Arrangements Market Structure and Competition written by James Bushnell and published by . This book was released on 2005 with total page 0 pages. 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.

Download or read book The Economics of Electricity Markets written by Darryl R. Biggar and published by John Wiley & Sons. This book was released on 2014-07-10 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges the knowledge gap between engineering and economics in a complex and evolving deregulated electricity industry, enabling readers to understand, operate, plan and design a modern power system With an accessible and progressive style written in straight-forward language, this book covers everything an engineer or economist needs to know to understand, operate within, plan and design an effective liberalized electricity industry, thus serving as both a useful teaching text and a valuable reference. The book focuses on principles and theory which are independent of any one market design. It outlines where the theory is not implemented in practice, perhaps due to other over-riding concerns. The book covers the basic modelling of electricity markets, including the impact of uncertainty (an integral part of generation investment decisions and transmission cost-benefit analysis). It draws out the parallels to the Nordpool market (an important point of reference for Europe). Written from the perspective of the policy-maker, the first part provides the introductory background knowledge required. This includes an understanding of basic economics concepts such as supply and demand, monopoly, market power and marginal cost. The second part of the book asks how a set of generation, load, and transmission resources should be efficiently operated, and the third part focuses on the generation investment decision. Part 4 addresses the question of the management of risk and Part 5 discusses the question of market power. Any power system must be operated at all times in a manner which can accommodate the next potential contingency. This demands responses by generators and loads on a very short timeframe. Part 6 of the book addresses the question of dispatch in the very short run, introducing the distinction between preventive and corrective actions and why preventive actions are sometimes required. The seventh part deals with pricing issues that arise under a regionally-priced market, such as the Australian NEM. This section introduces the notion of regions and interconnectors and how to formulate constraints for the correct pricing outcomes (the issue of "constraint orientation"). Part 8 addresses the fundamental and difficult issue of efficient transmission investment, and finally Part 9 covers issues that arise in the retail market. Bridges the gap between engineering and economics in electricity, covering both the economics and engineering knowledge needed to accurately understand, plan and develop the electricity market Comprehensive coverage of all the key topics in the economics of electricity markets Covers the latest research and policy issues as well as description of the fundamental concepts and principles that can be applied across all markets globally Numerous worked examples and end-of-chapter problems Companion website holding solutions to problems set out in the book, also the relevant simulation (GAMS) codes
