The European Commission moves forward on REMIT changes

The European Commission (EC) has published two draft regulations to update and strengthen the framework for transparency and integrity in the EU’s wholesale energy markets. These proposals revise Regulation (EU) No 1227/2011 on Wholesale Energy Market Integrity and Transparency and follow the May 2024 revision introduced under Regulation (EU) 2024/1106.

The changes are designed to address volatility in energy markets, geopolitical pressures, and the rise of new trading technologies. Together, the draft acts introduce adjustments to the Implementing Regulation (IR) and create new authorisation rules for Inside Information Platforms (IIPs) and Registered Reporting Mechanisms (RRMs).

Updates to REMIT Implementing Regulation

The draft Implementing Regulation proposes to repeal and replace the existing IR (Implementing Regulation (EU) No 1348/2014). The goal is to simplify reporting, resolve ambiguities, and align with the updated framework.

Key proposals include:

• Clearer rules for transactional data reporting

• Adjustments to disclosure requirements for inside information

• Minor updates to fundamental data reporting

• Stronger focus on data quality based on ACER’s monitoring experience

Authorisation of IIPs and RRMs

The draft Delegated Regulation introduces new rules for IIPs and RRMs, with ACER given authority over their authorisation, supervision, and potential withdrawal.

Proposed changes include:

• Data validation standards to improve accuracy and consistency

• A fast-track process for EU-established entities already registered

• Streamlined annual reporting requirements to reduce burdens

This framework is designed to ensure more reliable reporting while keeping compliance requirements proportionate.

Consultation and timeline for REMIT II

The EC opened its consultation in August 2025, with the deadline for comments set for 15 September 2025. Based on the legislative process, the likely sequence is:

• Q4 2025: EC finalises and adopts the Implementing and Delegated Acts

• Q4 2025 – Q1 2026: ACER publishes REMIT II technical documentation (final TRUM, annexes, XML/XSD schemas, and validation rules)

• Q4 2026 – Q1 2027: Go-live date for reporting obligations, depending on when the final Acts are published

Industry groups, including IOGP, are pressing for clearer deadlines on ACER’s publication of technical standards. Firms should expect final documentation shortly after the Commission adopts the measures.

Why this matters for compliance teams

The package will reshape reporting obligations across wholesale energy markets. With changes to data formats, validation rules, and disclosure requirements, firms will need to adapt their systems well in advance of the go-live date.

Reg-X Innovations can help firms prepare by:

• Mapping transactional and fundamental data to the revised REMIT requirements

• Handling exceptions and complex reporting scenarios based on industry-wide rules

• Supporting compliance teams through outsourced reporting or consulting services

Next steps

Firms should engage with the consultation process before the 15 September 2025 deadline and begin assessing their readiness for changes. Preparing early will help avoid disruption when the new rules take effect.
