The concept of a market participant
ACER generally considers at least the following types of entities to be market participants under REMIT when they enter into wholesale energy market transactions:
Energy trading companies
Producers (electricity / gas)
Shippers of natural gas
Balance responsible entities
Wholesale customers
Final customers
TSOs
DSOs
SSOs
Investment firms
Registration of the market participant
Who has to register?
All market participants entering into reportable wholesale energy market transactions must register with the national regulatory authority (NRA) in the Member State where they are established or resident. Non-EU participants may choose their NRA. Each participant can only register with one NRA. Participants in Germany register with the Bundesnetzagentur.
How is registration carried out?
Registration is performed online via CEREMP. It may be completed by an authorized person with a valid power of attorney, typically uploaded during the registration workflow.
Representatives of non-EU market participants
Third-country market participants who carry out reportable REMIT transactions must appoint a representative with authority to cooperate with NRAs or ACER.
Important:
Registration and representative appointment must be in the same Member State.

Definition & disclosure of inside information
What counts as "information"?
Under REMIT, "information" also covers planned or unplanned changes in capacity or output at facilities related to production, storage, consumption, transmission, and LNG.
Inside information criteria
- Precise in nature
- Not publicly available
- Related to wholesale energy products
- Would significantly affect prices if public
Disclosure requirements
ACER expects inside information to be disclosed through an Inside Information Platform (IIP). Publication on a website or social media can supplement but does not replace IIP disclosure.
Acronyms
MMBtu
1 Million British Thermal Units – a thermal unit of measurement for natural gas. Thermal units differ from pure volumetric units because they assume energy content. Gas that is more liquids-rich may have higher Btu content within the same volume compared to dry gas.
