Review of the reliability standards in EU electric power system

Bogovič, Jerneja (author)

Security of supply is one of the main objectives of a comprehensive package of EU legislative acts called Clean Energy for All Europeans. Through these legislative acts, the EU aims to accelerate the deployment of clean technologies, increase market competitiveness and energy efficiency, outline the design of the electricity market and security of supply, and create new rules for the governance of the Energy Union, making the European electricity market more interconnected, flexible and consumer-oriented.One of the main objectives is to determine the most efficient and effective way to ensure appropriate adequacy of generation units in the EU. In October 2020, European Union Agency for the Cooperation of Energy Regulators (ACER) presented the Methodology for calculating the value of lost load, the cost of new entry, and the reliability standard, which specifies the security of supply indexes and define the methodology for their calculation.Therefore, each EU Member State has to determine the value of lost load (VOLL), the cost of new entry (CONE) for different candidate technologies that are able to provide resource adequacy benefits (generation, storage and demand side response), and the reliability standard that consists of expected energy not served and loss of load expectation. The paper provides an overview of the methodology and results for countries that have already defined reliability standards according to the new methodology.
