Registration of market participants

The European Register of Market participants​

​​​​​Any market participant entering into transactions in one or more wholesale energy market in the EU has to register with the national regulatory authority (NRA) in the Member State they are established in or resident. This obligation applies to any person, as well as to non-EU and non-EEA market participants if they are active in the EU wholesale energy markets.  

On 26 June 2012, ACER adopted a Decision determining the registration format​ as the building block for establishing the European Register of Market participants. The registration format is the outcome of a strong cooperation with the NRAs, the ACER’s Board of Regulators (BoR), as well as of an extensive consultation with stakeholders. 

The CEREMP system

​The European Register allows to centralise market participants’ information across the EU, as each NRA in the Member States is required to establish a registration system. 

To support the NRAs, ACER has made the CEREMP​ system available to use at national level. However, the registration process is still managed nationally by the relevant NRA​.
