ACER’s recent Open Letter on Regulation (EU) 2026/256 clarifies critical updates to REMIT data reporting obligations.
ACER updates REMIT guidance on inside information reporting, introducing new requirements for UMMs, EIC codes, and data quality.
Summary of the joint ACER webinar held on 26 March 2026, covering current state and upcoming changes in transaction and fundamental data reporting under the revised REMIT framework.
The latest ACER REMIT Quarterly Report provides important updates on the REMIT framework, market monitoring activities and upcoming regulatory developments in the EU energy market.
The Commission Implementing Regulation (EU) 2026/256 sets rules for the provision of data to ACER regarding wholesale energy market transactions.
ACER (Agency for the Cooperation of Energy Regulators) has identified persistent data quality issues in reporting for partially matched orders (PMA – Partially Matched Orders) under REMIT (Regulation on Energy Market Integrity and Transparency) regulation.
On 8 September 2025, the European Commission adopted Decision (EU) 2025/1771, which introduces a new fee framework for ACER’s REMIT-related tasks.
RRMs (Registered Reporting Mechanisms) pay annually:
Flat registration fee: EUR 15,000
Transaction records fee component: based on data volumes and clusters (see below)
Risk position reporting fee: EUR 250 per report
IIPs (Inside Information Platforms): fixed annual fee of EUR 15,000

1,001–10,000 → EUR 1,000
10,001–100,000 → EUR 2,000

2025: one-off surcharge of EUR 7.6 million, allocated to RRMs according to the number of market participants (EUR 467.17 per MP).
2026: additional possible surcharge up to EUR 23.5 million, allocated according to data clusters.
On 8 September 2025, the European Commission adopted Decision (EU) 2025/1771, which repeals the previous Decision (EU) 2020/2152 and establishes a new fee scheme to finance the activities of ACER under the REMIT Regulation (EU) No 1227/2011.
ACER is responsible for monitoring Europe’s energy and trading markets. Due to new obligations – such as reporting on electricity, gas and hydrogen storage, capacity mechanisms, balancing services and high-frequency trading – ACER faces higher operating costs, which are now shared across market participants.
The financing is collected via Registered Reporting Mechanisms (RRMs):
The total fee for 2025 amounts to EUR 7.6 million.
This amount is distributed proportionally among all RRMs, based on the number of market participants (MPs) for whom transaction records were submitted between 1 January and 30 June 2025.
The rate per market participant is EUR 467.17.
ACER has provided RRMs with detailed lists of included MPs to enable verification of the calculation.
Increase transparency and ensure fair cost allocation.
Guarantee sustainable funding of REMIT-related activities, reducing reliance on the EU budget.
