ACER approves new methodology for national electricity flexibility assessments
The Agency for the Cooperation of Energy Regulators (ACER) has approved a new methodology for assessing national electricity flexibility needs, developed by the European Network for Transmission System Operators for Electricity (ENTSO-E) and the EU Distribution System Operators Entity (EU DSO Entity). Under the methodology, Member States must conduct national flexibility needs assessments within 12 months, submit findings to ACER and the European Commission by July 2026, and define indicative national targets for non-fossil flexibility by January 2027. These assessments will inform clean energy investment decisions, grid expansion and modernisation, and EU policy for cross-border flexibility deployment.
