Energy Identification Code

The Energy Identification Code or EIC is a 16-character code used in Europe to uniquely identify entities and objects related to the electricity and gas sector.

The EIC code is used for:

• Transmission System Operators, Market Participants etc.;
• Transmission lines and Metering points;
• Bidding Zones, Control Areas, Market Balance Areas etc.;
• Substations, Generation units and Power plants

The EIC codes are used -among others- in the ENTSO-E Transparency Platform and in the ARIS platform, both supporting EU regulations on transparency and integrity.

Actors involved in the EIC coding scheme

The scheme is supported by a central issuing office (“CIO”, function exercised by ENTSO-E for both the electricity and the gas sectors) and ENTSO-E-authorised local issuing offices (LIOs) in Europe.
