The European Commission revised the rules on financing of the European Union Agency for the Cooperation of Energy Regulators (ACER), warranting greater fairness and transparency. The new framework, set out in Commission Decision (EU) 2025/1771, has been applying since 15 September 2025.
Under the revised Regulation (EU) No 1227/2011 on wholesale energy market integrity and transparency (REMIT), ACER is entitled to collect fees from REMIT data reporting entities to cover a part of its operations (‘REMIT fees’). The new decision strengthens the long-term sustainability of ACER’s monitoring activities. It ensures that ACER has the resources needed to monitor the 47% annual increase in data reporting observed since 2021. In addition, the new fee system reflects ACER’s expanded supervisory and investigatory powers under the revised REMIT, including dealing with cross-border market abuse. This will strengthen the oversight of Europe’s energy markets at a time when transparency, consumer confidence and ensuring open and fair competition in the electricity and gas markets are more important than ever.
The updated fee system ensures that the costs of ACER’s monitoring activities under REMIT are shared fairly among reporting entities, based on the number of transaction records coming from the market participants on whose behalf they report to ACER, while at the same time preventing undue financial burden. Fees are calculated in a way that balances fixed annual contributions with variable fees linked to the level of market activity. This ensures that, when reporting entities further pass the costs on their clients, larger or market participants with higher volumes of transactions contribute more, while smaller market participants face proportionate obligations.
