Wholesale energy market integrity and transparency

The Regulation on Wholesale Energy Market Integrity and Transparency, known as the REMIT Regulation, came into force in 2011 to support open and fair competition in the European wholesale energy markets.

Consumers and other market participants need to have confidence in the integrity of electricity and natural gas markets, that prices are fair and competitive based on supply and demand, and that no profits can be drawn from market abuse.

In light of the evolving energy markets and the energy crisis, the Regulation on Wholesale Energy Market Integrity and Transparency (EU/1227/2011) was amended in May 2024 by Regulation (EU) 2024/1106 and Regulation (EU) 2024/1789.

REMIT framework

The regulation introduced a sector-specific framework for the monitoring of wholesale energy markets, with the objective of detecting and deterring market abuse. 

Under this framework, details of records of wholesale energy market transactions are reported by market participants, mostly through third parties called registered reporting mechanisms (RRMs), directly to the EU Agency for the Cooperation of Energy Regulators (ACER).

The market participants are also required to disclose inside information and submit inside information reports to ACER, mostly through third parties called inside information platforms (IIPs).

Revision of the REMIT Regulation

The REMIT framework was revised in 2024 to strengthen transparency and monitoring, align definitions and rules with financial market legislation, and improve enforcement, particularly for cross-border market abuse.

It broadens the scope of covered products and participants, while granting both ACER and national regulators (NRAs) enhanced powers to supervise, investigate, and, for NRAs to sanction misconduct, thereby supporting market integrity, price stability, and consumer protection.

The amendment also requires that all REMIT-related data should be reported to ACER via IIPs and RRMs.

As part of the revision, also the ACER Regulation (EU/2019/942) was amended by

  • extending the fee-paying requirement to IIPs
  • extending the scope of eligible costs possibly paid from fee revenues to the new supervision and investigatory powers given to ACER 

Between 18 August and 17 September 2025, the Commission collected feedback on 2 sets of draft rules developed under the REMIT regulation, as amended in 2024

  • proposal for a Delegated Regulation on IIPs and RRMs
  • proposal for amending the already existent Implementing Regulation (EU) 1348/2014 on data reporting

Fee-paying requirements

Based on the ACER Regulation, the collection of REMIT fees began in 2021 to support ACER in undertaking its REMIT activities. 

The fees were determined by the Commission’s 2020 Fees Decision (2020/2152).

The 2025 Fees Decision (EU/2025/1771) updates and adjusts the 2020 decision based on changes introduced in the revised REMIT, inflation, changes in the market (e.g. more high frequency trading) and almost 5 years of experience with its implementation.
