Energy Identification Codes

EIC system presentation

In order to ensure efficient data exchanges within the European energy market, ENTSO-E (European Network of Transmission System Operators for Electricity) implemented a common standard identification scheme: the EIC codes (Energy Identification Codes).

EIC codification scheme as well as the administrative organization for the EIC system are managed by ENTSO-E as Central issuing office (CIO).

Gas and electricity entities’ referencing is ensured by Local issuing offices (LIO). These LIOs operate at a national scale and are responsible for the allocation and management of EIC codes.

Since the 1st of July 2017, GRTgaz has been a Local issuing office whose LIO code is “63” (all the EIC codes delivered by GRTgaz start with these two digits: “63”). GRTgaz’ issuing office deals with every gas actor operating in France who ask for a EIC referencing for the first time. 

Electricity market entities continue to deal with RTE who has been the historical LIO for the French market.

For any further information, you can visit ENTSO-E website as well as the reference manual  « THE ENERGY IDENTIFICATION CODING SCHEME (EIC) REFERENCE MANUAL ».
