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.
ACER updates REMIT guidance on inside information reporting, introducing new requirements for UMMs, EIC codes, and data quality.
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.
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
a) Market participants on organised markets:
1–100 records → EUR 250
101–1,000 → EUR 500
1,001–10,000 → EUR 1,000
10,001–100,000 → EUR 2,000
100,001–1m → EUR 4,000
1m–10m → EUR 8,000
10m–100m → EUR 16,000
100m–1bn → EUR 32,000
1–2bn → EUR 64,000
2bn → EUR 96,000
b) Market participants outside organised markets:
1–10 records → EUR 250
11–100 → EUR 500
101–1,000 → EUR 1,000
1,001–10,000 → EUR 2,000
10,001–100,000 → EUR 4,000
100,001–1m → EUR 8,000
1m–10m → EUR 16,000
10m → EUR 32,000
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.

The European Commission has unveiled a new Implementing Regulation under REMIT (Regulation on Wholesale Energy Market Integrity and Transparency), replacing the existing Implementing Regulation (EU) No 1348/2014 after a 12-month transition. The reform aims to close loopholes, simplify procedures, and extend coverage to new energy markets such as LNG and hydrogen.
For the first time, liquefied natural gas (LNG) — and from 2028 also hydrogen — will fall under REMIT reporting obligations. Market participants will also have to provide exposure reports: forward-looking forecasts of generation, consumption, and hedging strategies over a 24-month horizon. ACER, the EU’s energy regulator, expects these reports to strengthen its ability to monitor for market abuse.
The regulation now distinguishes two types of reporting:
Continuous (D+2): e.g. exchange-traded contracts on Organised Market Places (OMPs).
Periodic (semi-annual or annual): for large OTC supply contracts above 600 GWh, storage and balancing services, capacity mechanisms, and hydrogen contracts.
For OTC deals, companies will have up to 10 working days to file reports — a notable change from continuous reporting under the old regime.
The technical annexes see major expansion:
Table 1 (standard contracts) grows from 58 to 89 fields, including many LNG-specific entries.
Table 2 now captures power purchase agreements (PPAs).
Tables 3 and 4 (electricity and gas transportation) add fields on capacity auctions and allocation mechanisms.
Table 5 is entirely new, covering trade-matching systems such as the Single Day-Ahead Coupling (SIDC).
All transactional and fundamental data must be routed through Registered Reporting Mechanisms (RRMs), while inside information disclosures will pass through newly designated Inside Information Platforms (IIPs). Both RRMs and IIPs are explicitly liable for ensuring the completeness, accuracy, and timeliness of reporting.
Trading venues (OMPs): required to deliver more detailed order and matching data.
Storage and LNG operators: now solely responsible for reporting, ending duplicate submissions by market participants.
Large suppliers and consumers: benefit from reduced OTC reporting frequency but face the new burden of exposure reporting.
Regulators: gain access to a broader and higher-quality dataset, reducing blind spots in market surveillance.
