ACER webinar: Streamlining capacity mechanisms with the updated ERAA methodology (26 May 2026)

ERAA is the annual assessment of the EU’s electricity supply adequacy for the next decade. It is developed by the European Network of Transmission System Operators for Electricity (ENTSO-E) and based on the methodology approved by ACER. ERAA’s purpose is to evaluate whether the EU has sufficient electricity resources to meet future demand and to identify potential risks to security of supply. In March 2026, ACER amended the ERAA methodology with the aim of: • supporting streamlined national capacity mechanisms approval under EU State Aid rules; • simplifying the methodology; • improving adequacy modelling. The aim of this webinar was to: • provide an overview of the updated methodology; and • discuss how it will help streamline the approval of capacity mechanisms and coordinate electricity adequacy policies across Member States.
