The Energy Identification Code (EIC) is a 16-character identifier (code) used in Europe to uniquely identify market participants and energy resources (entities and objects) related to the electricity and gas sector.
EIC codes are used for:
- Transmission System Operators, Market Participants such as traders, producers, consumers, power exchanges, grid operators, suppliers, agents, service providers, etc.
- Local grids where metering points are situated, Market Balance Areas consisting of several local grids, Control Areas, Bidding Zones, etc.
- The physical lines that connect adjacent market (balance) areas or internal lines within an area, including Transmission lines.
- Metering points
- Physical or logical places where an identified object or the IT system of an identified object is or could be located.
- Any object that generates or consumes energy, including Substations, Generation units and Power plants.
The EIC codes are used — among others — in platforms that support EU regulations on transparency and integrity:

Actors involved in the EIC coding scheme
The scheme is supported by a central issuing office (CIO), which function is exercised by the ENTSO-E Secretariat for both the electricity and gas sectors, and ENTSO-E-authorised Local Issuing Offices (LIOs) in Europe. As of 2024-12-17, there are 62 LIOs3
EIC consists of 16 characters structured as follows:45
- 2 digits: LIO id
- 1 letter: resource type as per the table below.
- 12 chars: LIO-specific identifier, padded on the right with dashes
- 1 char: checksum
EIC types (see EIC Definitions for more details6):
| type | name |
|---|---|
| A | Substation |
| T | Tieline |
| V | Location |
| W | Resource Object |
| X | Party |
| Y | Area or Domain |
| Z | Measurement point |
On 2021-12-16, IANA registered the urn:eic URN namespace,7 so now EIC can be used in making semantic triples of Common Information Model (electricity) data or other energy Linked Open Data.
