ACER's Board of Appeal begins a new five-year mandate

ACER’s Board of Appeal welcomes new members and alternates for a new five-year mandate, starting on 18 October 2026.

The appointment follows the public call for interest launched by the European Commission earlier this year. Members and alternates were appointed by ACER’s Administrative Board, following a proposal by the Commission and in consultation with ACER’s Board of Regulators.

Who are the new members & alternates?

Mr Carlos Batlle and Mr Adrien De Hauteclocque have been elected as new members. They join Mr Piet Eeckhout, Mr Miro Prek, Ms Keelin O'Brien and Ms Katerina Sardi, who will continue to serve the Board.

Ms Catherine Banet, Mr Ulrich Ehricke, Ms Edit Herczog and Mr Tony Rosten are appointed as alternates for the first time, while Mr Alain Marien and Mr Timo Partanen will continue in their role. Alternates may replace members who are unable to participate in Board proceedings.

Mr Volker Zuleger, ACER Acting Director, welcomes the new members and alternates and thanks those continuing for their commitment. Mr Zuleger also expresses his appreciation to the outgoing members and alternates for their service during the previous mandate.

More on the Board of Appeal

ACER’s Board of Appeal operates as an independent body to address complaints against ACER decisions. It is part of ACER but independent from its administrative and regulatory structure.

The Board is composed of six members and six alternates, serving a five-year mandate (renewable once). They are selected from current or former senior staff of national regulatory authorities, competition authorities or other national or EU institutions with relevant experience in the energy sector.
