Article 9 concerns the registration of market participants:

– Market participants entering into transactions for which a declaration to the Agency is mandatory (…) shall register with the national regulatory authority of the Member State in which they are established or resident or (…) of a Member State in which they exercise an activity. “(Article 9(1))
– Market participants (…) shall submit the registration form to the national regulatory authority before entering into a transaction” (Article 9(4)).

Principles of registration

– The registration of the market player is carried out with a single national regulator.
– It is the responsibility of the market participant to communicate to the national regulator any registry change
– Registration is in no way a licence or authorization to carry out transactions
– Each market player receives a unique identifier: the ACER code.

In particular, entities that may be required to report to ACER with the following data (Article 4 of the implementing acts) :
– Intra-group transactions and contracts
– Balancing and balancing contracts

ACER publishes and frequently updates the list of actors registered at the European level as well as their ACER8 code
