Today, ACER opens a public consultation to refine the content and structure of its new guideline on transaction reporting under the recently updated REMIT framework.
What is it about?
Europe has an EU-wide framework (“REMIT”) to detect and deter market manipulation and abuse in wholesale energy markets. The Regulation was revised in 2024 to keep pace with evolving market dynamics. To make the framework fully operational, REMIT secondary legislation has also been updated (April 2026) with a recast REMIT Implementing Regulation and a new Delegated Regulation.
Together, these two acts aim to improve standardised data reporting, strengthen the supervision of reporting entities and help ensure transparency and integrity in EU wholesale energy markets.
Why are we consulting?
To help market participants meet their data reporting obligations, ACER has developed a consolidated guideline on REMIT transaction reporting. The document:
- clarifies key definitions (e.g. who must report, what and when); and
- separates technical instructions from policy‑related aspects of REMIT data reporting.
ACER is seeking stakeholder input to ensure the guideline is clear, practical and supports uniform data reporting across the EU.
