The Board of Appeal (BoA) deals with complaints lodged against ACER decisions. Any natural or legal person can appeal against a decision taken by ACER where the Agency has actual decision-making powers (individual decisions).

The decisions of the Board of Appeal may as well be subject to appeal before the Court of Justice of the European Communities.​

The Board of Appeal is part of ACER but at the same time independent from its administrative and regulatory structure. It is essential that members and alternates act independently and in the public interest.

The Board of Appeal is composed by six members and six alternates for a mandate of 5 years (renewable).

Members and alternates are selected among current or former senior staff of the national regulatory authorities, competition authorities or other national or EU institutions with relevant experience in the energy sector.​

​The Board of Appeal encourages online communication via e-mail. Correspondents in appeal proceedings are asked to submit documents as electronic files.

A word from Christian on his re-appointment as ACER Director (from Jan 2025-end Dec 2029):

“I am honoured to have the trust and confidence of the ACER Boards to steer the Agency through its evolving mandate for the coming years. At ACER, we understand the real-world energy challenges and trade-offs that governments and stakeholders face. One such key challenge facing Europe, and a promise of the European Commission under its new political mandate, is to enhance EU competitiveness while reducing energy bills for companies and households. A key component here will be how Europe’s integrated energy markets evolve in the years ahead. Naturally ACER and our members, the National Regulatory Authorities (NRAs), will have a key role to play here if leaders across the EU decide to leverage further this potential asset.

Building trust is not built solely on shared values but also through ACER’s daily graft alongside the NRAs of monitoring energy markets and networks to ensure the rules are respected, removing barriers, increasing transparency, analysing data to detect market manipulation and insider trading, and providing evidence-based insights that help decision-makers make informed decisions about the trade-offs they face. As the saying goes, ‘The only easy day was yesterday’, reflecting that as our energy transition unfolds, there will be ample new and exciting challenges to devote ourselves to.”

The ACER Administrative Board (at its 11-12 December 2024 meeting) extended the mandate of the Director, Mr Christian Zinglersen, for five years.

A word from Christian on his appointment as ACER Director (from Jan 2020-end Dec 2024):

​​​​​“I am thrilled to be, together with the Agency, at the front line, regulation-wise, of the many changes impacting energy systems in Europe. The energy landscape is evolving rapidly, driven in part by technology, by market actor innovation and in part by evolving political priorities, not least as regards decarbonisation of the broader economy, in which energy transitions play a crucial part. 

While history shows that trust among nations in moments of crisis tends to decrease, I remain firmly convinced that in the coming months and years we need “more Europe”, not less. ACER will play a key role, to the extent possible, to build faith in increased mutual reliance, which I see as being the essence of its mandate”.

The Annual Work programme contains ACER's multi-annual outlook, priorities and strategies. 

It is prepared by the Director and adopted by the Administrative Board.

​Before its adoption, the Administrative Board consults the European Commission and must receive a favourable opinion from the Board of Regulators on the ​​regulatory outline.
 

After the adoption, the Administrative Board transmits the Work programme to the European Parliament, the Council of the European Union and the Commission. 

The Work pr​​ogramme is then made public.​

Every year ACER produces a Consolidated Annual Activity Report (CAAR) describing the activities performed and the objectives achieved during the year, as indicated in the Wo​rk Programme.

After screening the alerts, ACER performs an in-depth analysis of the observed suspicious behaviour by using a series of sophisticated tools. These tools allow the analysts to get specific statistics per market participant, for instance their trading behaviour per delivery point or zone, as well as cross-border trading.
