ACER releases today an Opinion assessing whether the European transmission system operators (TSOs) followed the EU legal and regulatory framework when performing their bidding zone review study published on 28 April 2025.
Congratulations to Emmanuelle Wargon and George Niculescu for their appointment as Chair and Vice Chair of ACER's Board of Regulators respectively, and to Volker Zuleger for his appointment as ACER Director ad interim.
On 4 August 2025, ACER received two proposals from all nominated electricity market operators (NEMOs) to amend the harmonised maximum and minimum clearing price (HMMCP) methodologies for the European day-ahead and intraday markets, respectively.
ACER publishes its Opinion on the updated manual of procedures for the European Network of Transmission System Operators for Electricity (ENTSO-E) Transparency Platform, submitted on 8 July 2025.
To keep up with evolving regulatory and technical requirements (including the 2024 revision of REMIT), ACER plans to update the REMIT market participant registration format and the Centralised European Register of Energy Market Participants platform.
ACER’s 2026 Monitoring Report on energy infrastructure development in Europe examines whether electricity, gas and hydrogen networks are adapting to changing energy needs, and what this means in terms of investment costs, delays and costs for consumers.
