ACER sets the methodologies to assess electricity resource adequacy in the EU


National Energy Regulatory Council (NERC) which participates in the activities of EU Agency for the Cooperation of Energy Regulators (ACER), informs that ACER on 2nd of October published decisions on the methodology for the European resource adequacy assessment (ERAA) and methodology regarding calculating the value of lost load, the cost of new entry and the reliability standard.

The ERAA describes the expected level of security of supply for a ten-year horizon. 

Member States set a reliability standard based on the value of lost load and the cost of new entry for generation or demand response. The reliability standard indicates the necessary level of security of supply of the Member State.

By comparing these results, resource adequacy concerns can be identified, and the need for additional measures (e.g. temporary capacity mechanisms) assessed.

Regarding this methodology ENTSO-E (the European Network of Transmission System Operators for Electricity) runs a simulation model based on data provided by the Transmission System Operators (TSOs) for demand, supply and the power grid. ENTSO-E currently performs the European Mid-term Adequacy Forecast (MAF) with a ten-year time horizon. After that, a ERAA will gradually be implemented and may be complemented by national resource adequacy assessments.
