Trading participants that conclude transactions on an OMP are obliged to register as market participants before they start trading. Since EEX, Gaspoint Nordic and Powernext have been recognised as OMPs by ACER, all trading participants need to register.

Pursuant to Article 9 of REMIT, the registration is mandatory for all market participants. Market participants are all members that conclude transactions which are reportable according to Article 8 Paragraph 1 of the REMIT Implementing Regulation.

Registration shall be made with the National Regulatory Authority (NRA) of the member state within which the market participant is established or resident. If a market participant is not based in the European Union, registration shall be made with the NRA of a member state within which it operates.

ACER has specified the data to be provided for the registration as well as the format. More detailed information on the registration process has been published by the NRAs.
