New regulations on REMIT fees implemented by the European Commission

The European Commission has recently made revisions to the rules governing the financing of the European Union Agency for the Cooperation of Energy Regulators (ACER), with the aim of enhancing fairness and transparency in the process. The implementation of the new framework, as specified in Commission Decision (EU) 2025/1771, took effect on 15 September 2025.

As per the updated Regulation (EU) No 1227/2011 on wholesale energy market integrity and transparency (REMIT), ACER has the authority to levy fees from REMIT data reporting entities to support a portion of its operational costs (referred to as ‘REMIT fees’). The recent decision is geared towards bolstering the long-term sustainability of ACER’s monitoring activities. It ensures that ACER is adequately equipped with the necessary resources to handle the 47% yearly surge in data reporting witnessed since 2021. Furthermore, the new fee structure takes into account ACER’s expanded supervisory and investigative powers under the revised REMIT, particularly in addressing instances of cross-border market abuse. This move is expected to reinforce the oversight of Europe’s energy markets, especially at a time when transparency, consumer confidence, and the promotion of open and fair competition in the electricity and gas sectors are paramount.

The updated fee system has been designed to ensure that the costs associated with ACER’s monitoring endeavors under REMIT are distributed equitably among reporting entities. This allocation is based on the volume of transaction records submitted by market participants on behalf of whom they report to ACER, thereby preventing any undue financial burden. The fee calculation methodology strikes a balance between fixed annual contributions and variable fees tied to market activity levels. This approach guarantees that larger market participants or those with higher transaction volumes bear a greater portion of the costs, while smaller players face commensurate obligations.

REMIT, which sets out EU-wide regulations aimed at preserving the integrity of the EU’s wholesale energy markets, prohibits insider trading and market manipulation. By ensuring that market prices reflect genuine supply and demand, the legislation serves to protect consumers and businesses from unfair practices. ACER assumes a central role in overseeing the trading activities of market participants in energy markets and in collating transaction data from across the EU. Adequate funding is crucial for ACER to fulfill its monitoring responsibilities effectively. The fee structure outlined in the recent decision guarantees that entities benefiting from engagement in EU energy markets by offering reporting services to energy firms and system operators contribute towards the monitoring costs.
