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.

Available in PDF, EPUB and Kindle. Book excerpt: I study the role of purely financial players in electricity markets, where they trade alongside physical buyers and sellers. In this context, physical sellers intertemporally price discriminate, leading to price differences that financial traders arbitrage, thus restricting producers' market power. Using detailed individual data, I examine physical and financial firms' response to regulation that exogenously increased financial trading. I show that the effect of financial traders on generators' market power depends on whether firms are in a static Nash equilibrium or not. I then develop a structural test of static Nash equilibrium and show the null of static Nash does not hold during the period of reduced financial trading. To implement the test, I present a new method to study the competitive structure of electricity markets using machine learning tools to define markets. I find that increased financial trading reduced generators' market power and increased consumer surplus.

Available in PDF, EPUB and Kindle. Book excerpt: "This paper first describes those features of the electricity supply industry that make a prospective market monitoring process essential to a well-functioning wholesale market. Some of these features are shared with the securities industry, although the technology of electricity production and delivery make a reliable transmission network a necessary condition for an efficient wholesale market. These features of the electricity supply industry also make antitrust or competition law alone an inadequate foundation for an electricity market monitoring process.

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.

This book was released on 2010 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis current questions regarding the functionality of liberalized electricity markets are studied addressing different topics of interest in two main directions: market power and competition policy on electricity wholesale markets, and network investments and incentive regulation. The former is studied based on the case of the German electricity market with respect to ex-post market power analysis and ex-ante remedy development. First an optimization model is designed to obtain the competitive benchmark which can be compared to the observed market outcomes between 2004 and 2006. In a second step the horizontal breaking up of dominant firms (divestiture) is simulated applying equilibrium techniques (the classical Cournot approach and the Supply Function Equilibrium approach). The later issue of transmission capacity investment is addressed by highlighting the complexity of network investments in electricity markets and by analyzing a regulatory mechanism with a two part tariff approach. The technical characteristics of power flows are combined with economic criteria and tested for different network settings.

This book was released on 2000-02-01 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines the degree of competition in the Cal. wholesale electricity market during the period June 1998 to Sep. 1999 by comparing the market prices with estimates of the prices that would have resulted if owners of instate fossil fuel generating facilities behaved as price takers. There were significant departures from competitive pricing and these departures are most pronounced during the highest demand periods, which tend to occur during the months of July-Sep. Through most of the winter and spring of 1999 there was little evidence of the exercise of market power. The exercise of market power raised the cost of power purchases by about 16% above the competitive level.

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 Competition and Regulation in Electricity Markets written by Sebastian Eyre and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring an original introduction by the editors, these carefully-selected essays explore the main issues surrounding competition and regulation in electricity markets. The industry is experiencing irresistible forces of change, driven by energy policy objectives; a reassessment of market regulation in the face of high-energy prices; and the response to consumer pressure to agree on what constitutes a fair price for energy. This volume identifies the key articles that underpin the debate across the industries supply chain (generation, supply and networks) from a regulatory perspective (including market power and incentive regulation). The collection then considers the overall impact of liberalisation and future developments.

Overall, the exercise of market power raised the cost of power purchases by about 16% above the competitive level. Following the presentation of our methodology for computing the counterfactual price-taking market price, we describe why our calculation represents a lower bound on the extent of market power and why the observed market prices cannot by attributed to competitive peak-lead pricing

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.

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.
Download or read book Marginal Cost Pricing in a World without Perfect Competition Implications for Electricity Markets with High Shares of Low Marginal Cost Resources written by and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common approach to regulating electricity is through auction-based competitive wholesale markets. The goal of this approach is to provide a reliable supply of power at the lowest reasonable cost to the consumer. This necessitates market structures and operating rules that ensure revenue sufficiency for all generators needed for resource adequacy purposes. Wholesale electricity markets employ marginal-cost pricing to provide cost-effective dispatch such that resources are compensated for their operational costs. However, marginal-cost pricing alone cannot guarantee cost recovery outside of perfect competition, and electricity markets have at least six attributes that preclude them from functioning as perfectly competitive markets. These attributes include market power, externalities, public good attributes, lack of storage, wholesale price caps, and ineffective demand curve. Until (and unless) these failures are ameliorated, some form of corrective action(s) will be necessary to improve market efficiency so that prices can correctly reflect the needed level of system reliability. Many of these options necessarily involve some form of administrative or out-of-market actions, such as scarcity pricing, capacity payments, bilateral or other out-of-market contracts, or some hybrid combination. A key focus with these options is to create a connection between the electricity market and long-term reliability/loss-of-load expectation targets, which are inherently disconnected in the native markets because of the aforementioned market failures. The addition of variable generation resources can exacerbate revenue sufficiency and resource adequacy concerns caused by these underlying market failures. Because variable generation resources have near-zero marginal costs, they effectively suppress energy prices and reduce the capacity factors of conventional generators through the merit-order effect in the simplest case of a convex market; non-convexities can also suppress prices.
