EIC Issuing Office (12)

Swissgrid acts as the Swiss EIC Issuing Office. Alongside electrical energy, it assumes responsibility for other sources of energy such as gas.

Clear rules and coordinated terms are required to ensure uniform electronic data exchange between among the various parties involved. To guarantee this, ETSO has developed the uniform Energy Identification Code (EIC) system. This coding system is used for:

  • schedule management based on the ETSO Scheduling System (ESS)
  • data exchange (metering data and change processes) according to SDAT-CH

On the website of the Association of Swiss Electricity Companies (Verband Schweizerischer Elektrizitätsunternehmen, VSE) you will find the document (in German) on standardised data exchange for the Swiss electricity market. It states that all players involved in data exchange must be clearly identified by means of a code. The EIC is used for this purpose.

A distinction is made between various code types in the EIC:

X codeIdentifies a player (party), in other words a company (one code per VAT number). Irrespective of their role in the market or the source of energy. The role of grid operator was defined as a special case in SDAT-CH. A separate EIC is to be utilised in this role.
Y codeIdentifies an area, in other words a grid. In international usage, a Y code may also be necessary for an accounting area, balance groups or similar.
W codeIdentifies a resource object, such as a generating unit or a generator. These codes are generally generated directly by Swissgrid during the regular AS pre-qualification process and shared with the ASP.
V codeIdentifies a logical or physical place and is issued in particular during registration for communication via ECP (Energy Communication Platform) to identify IT systems.

Additional documentation on possible types and their application can be found in the EIC documentation from ENTSO-E.

EIC application

Possession of an EIC does not automatically authorise participation in a specific process in the energy market. The holder of an EIC is personally responsible for complying with industry specifications and qualification processes.

Should a code be used in the international environment, it must also be registered with ENTSO-E. This can only take place through the local issuing office to which the application for the code has been or is being sent.

Please send the completely filled-in EIC application by e-mail to Swissgrid.


  1. Only EIC codes published in the CIO or LIO website are to be considered as valid EIC codes.
