ACER did not approve the first two ERAAs submitted by ENTSO-E. The ACER decisions provided recommendations to ENTSO-E to improve their subsequent ERAA.
ACER intends to decide on the proposed amendments in cooperation with Core regulatory authorities and TSOs, and thus enable the first intraday flow-based capacity calculation in Europe.
ACER publishes a set of UIC indicators and corresponding reference values for the comparison of unit investment costs for comparable projects of the energy infrastructure categories.
The Baltic energy regulators (Estonia, Finland, Latvia, Lithuania, Poland and Sweden) requested from ACER a three-month extension to decide on the capacity calculation methodology for long-term timeframes.
ENTSO-E submitted its proposal for ERAA 2024 for ACER approval in April 2025. ACER will issue its decision in July 2025. ACER also requested ENTSO-E to propose amendments to the ERAA methodology by mid-October 2025.
