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.

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.

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.

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.

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 Power Market Structure written by Maria Vagliasindi and published by World Bank Publications. This book was released on 2013-03-28 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current distribution of power markets around intermediate structures that fall between the two extremes of full integration and unbundling suggests that there has not been a linear path to power market structure reform. Rather, many developing countries may retain intermediate structures into the foreseeable future. This possibility exposes a gap in the understanding of power market structures, since most theoretical work has focused on the two extreme possibilities and there is limited evidence of the impact of unbundling for developing countries. Power Market Structure takes a novel analytical approach to modeling market structure, together with ownership and regulation, in determining performance across several indicators, including access, operational and financial performance, and environmental sustainability. Its conclusions--which will be of particular interest to policy makers, academics, and development practitioners--reflect evidence drawn from statistical analysis and a representative sample of 20 case studies, selected based on initial conditions such as income and power system size. The key result of the analysis is that unbundling delivers results when used as an entry point to implementing broader reforms, particularly introducing a sound regulatory framework, and reducing the degree of concentration of the generation and distribution segments of the market by attracting additional public and private players and greater private sector participation. In addition, there seems to be a credible empirical basis for selecting a threshold power system size and per capita income level below which unbundling of the power supply chain is not expected to be worthwhile. Partial forms of vertical unbundling do not appear to drive improvements. The most likely reason is that the owner was able to continue exercising control over the affairs of the sector and hinder the development of competitive pressure within the power market.

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.

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

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.
