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.

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.

This paper investigates the regulatory rules of market transparency which could be applied within the wholesale electricity market and market for frequency and voltage control in the Web-of-Cells (WoC) decentralized power control architecture, which has been developed in the ELECTRA Project to respond the challenges and needs of the future power system (2030+). In this decentralized functional architecture for frequency and voltage control, the European Union (EU) power grid is divided into grid control areas, i.e., cells, which are defined as portions of the grid having adequate monitoring infrastructure and local reserves capacity, allowing voltage and balancing (frequency) problems to be solved at cell level, under the responsibility of a Cell System Operator (CSO) (present Distribution System Operator (DSO)/Transmission System Operator (TSO)). In order to foster the practical realization of the WoC-based architecture, the related wholesale electricity market and market for frequency and voltage control are proposed considering the competitive market principles, including transparency. The critical review of the existing EU regulations dealing with this issue suggests respecting the valid provisions on market transparency while tailoring them into the WoC-based architecture. Moreover, in order to take into account the WoC peculiarities, a set of integrations to the current regulatory rules is also proposed, addressing: (1) disclosure of information in respect to attributes of emerging technologies such as renewable energy sources (RES), distributed energy resources (DER), storage; (2) provision of generation and load forecast information; (3) process of procurement of flexibilities; (4) retail market transparency; (5) disclosure of privacy-sensitive household attributes; and (6) disclosure of information on market for frequency and voltage control.

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>

Each country strives for growing economic development, but no country is able to implement it. Various experiences and projects from the countries of the European Union and other neighboring countries are taken and considered. Towards the end of the 20th century and at the beginning of the 21st century, economic movements are increasingly relying on public-private partnerships, which can lead to a rapid development process through the financing of infrastructure projects. Economic globalization, as well as the emergence of new opportunities for economic activity in the world, are aimed at cooperation of the authorities and businesses in the realization of the socio-economic policies. The implementation and realization of development projects through public-private partnerships is impossible without participation by the relevant institutions of the public and private sector. Above all, direct participation implies expertise, experience and education. Every project that will be realized through various forms of public-private partnership must fulfill certain conditions. Among the conditions for proper implementation of the project are: dialogue, transparency and monitoring. The main feature of PPP is the transfer of the risk to the financing, efficiency and quality of public services, which are usually the burden of the private partner. This paper analyzes and explores the essence of public-private partnership. The conceptual framework for public-private partnership, as well as its strengths and weaknesses, is set. With the application of PPP, the economic development of the infrastructure as a whole, and in particular the development of local infrastructure, is analyzed. The origin of PPPs, its characteristics, as well as the need and importance for their continuous implementation are explained. The application of PPP is considered through the experiences in certain countries of the European Union and the Republic of Macedonia. Then, the responses to previously hypothesized hypotheses are collected: what is the successful implementation of PPP, what is needed for PPPs and why. In the end, the data from the conducted research are collected, analyzed and determined the profile of certain activities, as well as the possible decisions for further strategies for the implementation of the PPPs.

The main purpose of the article is to present how the Greek- -Macedonian naming dispute influenced the problem of implementation the international identity of Macedonia. Despite the initial problems of the government in Skopje related to determining their international identity, Macedonians managed to define the principles regarding the identification of a new state on the international stage. As a small country with limited attributes to shape its international position, Macedonia has basically been determined to seek guarantees for its existence and security in stable and predictable European international structures such as NATO and the European Union. The main obstacle for Macedonians on the road to Euro-Atlantic structures was the veto of Greece, a member of these organizations, resulting from Athens’ refusal to accept the name the Republic of Macedonia. The Prespa Agreement of 2018 gave a new impetus to the realization of the international identity of North Macedonia.

Flexibility Index

AbstractDuring peak electricity demand periods, prices in wholesale markets can be up to nine times higher than during off-peak periods. This is because if a vast number of users is consuming electricity at the same time, power plants with higher greenhouse gas emissions and higher system costs are typically activated. In the UK, the residential sector is responsible for about one third of overall electricity demand and up to 60% of peak demand. This paper presents an analysis of the 2014–2015 Office for National Statistics National Time Use Survey with a view to derive an intrinsic flexibility index based on timing of residential electricity demand. It analyses how the intrinsic flexibility varies compared with wholesale electricity market prices. Findings show that spot prices and intrinsic flexibility to shift activities vary harmoniously throughout the day. Reflections are also drawn on the application of this research to work on demand side flexibility.
