Issuance of EIC

Each participant in the Greek and European Electricity Market is identified by a code, the Energy Identification Code (EIC), which follows the Participant in all its transactions. The HETS Operator is the Local Issuing Office in Greece authorised by ENTSO-E.

 The list of EIC codes already assigned by the HETS Operator is the following:

As the EIC codes are unique, a market participant  who already has an EIC code, does not need to apply to the HETS Operator for a new EIC code. Also, EIC is only a coding scheme and it is not a right or authorization to trade energy.

For the allocation of an EIC code, the participant must submit the following application form and  forward it to the Operator of HETS via fax or mail.

For the update of an existing EIC code, the EIC participant, owner of the EIC code, must submit the following application form and forward it to the HETS Operator via email, fax or mail.

For more information you can contact the EIC Code Office by email at or by phone at 210-9466801, or by fax at 210-4637111.


You can find more information about the EIC codes at the web page provided by ENTSO-E:
