Wholesale Electricity Market

<p class="ESRBODY">The French wholesale market is set to expand in the next few years under European pressures and national decisions. In this paper, we investigate the performance of the French wholesale power market to examine whether or not the equilibrium outcomes are competitive. After a literature review on the different existing models, an extension of the Bresnahan - Lau (1982) method in panel data framework is employed with hourly dataset during 2009-2012 on the French wholesale market. The model-based results suggest that though market power is found statistically significant in several peak-load hours, it stays at very low level. On average, no market power is exercised over the examined period. These results correspond with the extremely regulated wholesale power market in France. It is of high interest given the future evolution of the French wholesale market which will be among the biggest in Europe in 2016 after the end of regulated tariffs for all firms.</p>

The participation of household prosumers in wholesale electricity markets is very limited, considering the minimum participation limit imposed by most market participation rules. The generation capacity of households has been increasing since the installation of distributed generation from renewable sources in their facilities brings advantages for themselves and the system. Due to the growth of self-consumption, network operators have been putting aside the purchase of electricity from households, and there has been a reduction in the price of these transactions. This paper proposes an innovative model that uses the aggregation of households to reach the minimum limits of electricity volume needed to participate in the wholesale market. In this way, the Aggregator represents the community of households in market sales and purchases. An electricity transactions portfolio optimization model is proposed to enable the Aggregator reaching the decisions on which markets to participate to maximize the market negotiation outcomes, considering the day-ahead market, intra-day market, and retail market. A case study is presented, considering the Iberian wholesale electricity market and the Portuguese retail market. A community of 50 prosumers equipped with photovoltaic generators and individual storage systems is used to carry out the experiments. A cost reduction of 6–11% is achieved when the community of households buys and sells electricity in the wholesale market through the Aggregator.

Of Greece

The European Union Target Model aims to integrate European energy market by removing barriers to trade and align markets. The most important goals of the Target Model are to provide consistent prices, enhance liquidity, support cross boarder trading, facilitate interconnections, and coordinate the use of transmission system capacity. In that context, the smooth operation of both forward and spot markets is a core development that directly affects the good operation of the wholesale market. This paper examines the application of the Target Model in the wholesale electricity market of Greece and its impact on electricity prices. The study explores the time period before the implementation of the Target Model, which took place on November 2020, and the first nine months of its execution. Based on the feedback received by the rest of the European countries, which are already part of the European Single Market, this crucial period of time is considered transitional, when many distortions and unethical behaviors take place. Empirical findings indicate a relatively successful implementation of the Target Model in Greece, with price disorders mostly met in the Balancing Market.

And Control

In today's competitive market, deregulation of power industry is inevitable. The aim of deregulating the power markets is to bring competition into them and thereby make them more economically efficient. In an economically efficient market, no consumer or producer has the ability to impact on prices by itself or by collaborating with any other participant. However, the electricity wholesale market is not a perfect market and the potential for market power exploitation is an issue. Sometimes private companies collaborate with each other to get more profit, driving the prices to a higher level and thus acquiring a market power which is an anti-competitive practice. Thus, market power is the capability of a seller or a group of sellers to profitably maintain the prices above a competitive level and control the total output for a noteworthy period of time.

Abstract Due to environmental and resiliency benefits, distributed energy resources (DER) are a potential solution for meeting future electricity demand, but their integration into centralized power markets on the large scale is challenging. Many practitioners argue that blockchain technology can create new market structures for DER like local peer-to-peer energy markets which foster renewable generation. To get an understanding of the status quo of the research on blockchain-based energy exchange, we conducted a systematic literature review on the existing academic articles and industry projects. This article describes the design and technical specifications of the first real blockchain-based electricity market in Switzerland derived from this literature review and outlines the implementation of this market in the real world. The findings provide valuable guidelines for the integration of DER into future sustainable energy markets.

The Relationship

This article reviews various paths of possible development of wholesale and retail electric power markets. The authors analyse the electric power market target model whose implementa-tion is to start from 2012. Also an alternative model is described, whose purpose is to facilitate creation of a healthy competitive environment. In this model a retail supplier plays a role of bro-ker for a customer, which may freely choose a generating company - an electric power supplier. This model alleviates the relationship between sales companies and power network companies; the risk of non-payment in retail segment is transferred from intermediary to electric power sup-plier. Besides, for the purpose of decreasing risks of electric power rates fluctuation, this model suggests introduction of a special mechanism damping wholesale market rate oscillations. This mechanism may be implemented by a dedicated insurance fund.
