ACER consults on methodologies for assessing electricity resource adequacy


​The European Union (EU) Agency for the Cooperation of Energy Regulators (ACER) has launched today a public consultation to decide on the methodologies for assessing whether the EU, as a whole, has sufficient electricity resources to meet its future electricity needs. These methodologies, mandated by the Clean Energy Package legislation, are key in ensuring and improving the reliability of Europe's electricity supply.

The methodologies, developed by the European Network of Transmission System Operators for Electricity (ENTSO-E) and submitted to ACER for approval, are:

  • ​Methodology for the European resource adequacy assessment (ERAA) to be conducted every year by ENTSO-E based on the data provided by national transmission system operators. This will allow assessing the overall adequacy of the electricity system to supply current and projected demands for electricity at Union level, at the level of Member States and at the level of individual bidding zones.
  • Methodology for calculating the value of lost load, the cost of new entry and the reliability standard (VoLL, CoNE, RS) to provide the Member States with a common approach for determining their desired levels of security of electricity supply.

ACER is competent to decide on these proposals in accordance with its founding Regulation and the recast Electricity Regulation, amending them where necessary.

In order to inform our decisions, we are seeking views from all the interested parties during a three-week public consultation, until 27 May 2020.
