Shall TSOs register as market participants, reporting parties or both?

Answer: Any entity that identifies itself as a market participant, under Article 2(7) of REMIT, should register as such with the relevant NRA, in line with the provisions of Article 9(1) of REMIT. Article 2(7) of REMIT defines that ‘“market participant” may be any person, including transmission system operators, distribution system operators, storage system operators and LNG system operators, who enters into transactions, including the placing of orders to trade, in one or more wholesale energy markets.’

If the market participant intends to report directly its own data relating to OTC^[6] (self-reporting), it should indicate this via CEREMP (Section 5 of the registration form) and be authorised as a registered reporting mechanisms (RRM) by the Agency in accordance with Article 9a of REMIT.^[7]

A market participant who does not intend to self-report its data relating to OTC has to indicate which RRM service(s) it intends to use via CEREMP (CEREMP - Section 5).

[6] Reporting of records of transactions, including orders to trade, that are entered into, concluded or executed at OMPs shall be reported to the Agency, via RRM, by the OMP in accordance with Article 8(1a)(a) of REMIT [7] By 8 May 2025, the European Commission shall adopt a delegated act further detailing the authorisation and supervision of registered reporting mechanisms.
