The list of Registered Reporting Mechanisms (RRMs) is an official register maintained by ACER under REMIT, identifying all entities authorised to report wholesale energy market transactions on behalf of market participants. RRMs – such as trading venues, trade repositories and approved third-party service providers – play a critical role in ensuring compliance with REMIT’s reporting obligations by submitting accurate and timely transaction data to ACER. Market participants must use an ACER-registered RRM to fulfil their reporting requirements.
Since 2015, all entities wishing to operate as RRMs must apply via ACER’s RRM registration tool. If they comply with ACER’s requirements, reporting parties are successfully registered and authorised to start reporting.
From November 2027, the current registration process will be replaced by an authorisation regime (under the Delegated Regulation).
Please see below the list of registered RRMs.
