The Regulation on Wholesale Energy Market Integrity and Transparency (REMIT) is the EU framework that protects consumers and businesses from energy market manipulation and insider trading.
Under REMIT, all market participants must register with the national regulatory authority in the country where they operate. Each regulator is responsible for establishing and maintaining a national register of market participants.
At EU level, ACER manages the European register of market participants, which is publicly available through the Centralised European Register of Energy Market Participants (CEREMP) platform and collects Member States’ national registers.
To ensure consistent data collection across the EU, ACER established a common registration format in 2012.
Why consult?
To keep up with evolving regulatory and technical requirements (including the 2024 revision of REMIT), ACER plans to update both the registration format and the CEREMP platform.
Next steps
To inform its decision-making, ACER will seek stakeholders’ feedback on possible amendments from 1 to 29 October 2025.
