EIC codes for European bidding zones

An EIC (Energy Identification Code) is the 16-character identifier ENTSO-E uses for bidding zones, control areas, market parties and physical objects — for example 10Y1001A1001A82H for Germany–Luxembourg (DE-LU) and 10YCZ-CEPS-----N for Czechia. This page lists the EIC codes of 44 European bidding zones, plus the documentType and processType codes an ENTSO-E API query needs.

Every ENTSO-E query needs a domain parameter, and every domain parameter is an EIC code. This is the lookup table, plus the document and process types you will need next. Click a code to copy it.

What is an EIC code?

An EIC — Energy Identification Code — is the 16-character identifier used across European electricity and gas markets for areas, market parties and physical objects. ENTSO-E runs the scheme and issues codes through local issuing offices. The first two characters name the issuing office, the third says what kind of object it is (Y for areas such as bidding zones and control areas, X for market parties, W for resources such as power plants), and the last character is a check character. So 10YCZ-CEPS-----N is an area code issued centrally by ENTSO-E: the Czech bidding zone.

You meet them in every ENTSO-E query and on the Transparency Platform; the bidding zone codes are listed below.

Document types

What kind of data you are asking for. Pass as documentType.

Process types

Which run of the data. Pass as processType — the same document type means different things depending on it.

Using them

Depending on the document, the domain parameter is in_Domain, outBiddingZone_Domain or controlArea_Domain. Using the wrong one returns an empty response rather than an error, which is the most common reason a query “does not work”. We cover that and the rest in the guide to the ENTSO-E API.

Frequently asked questions

What is an EIC code?

An EIC (Energy Identification Code) is a 16-character identifier used in European electricity and gas markets for areas, market parties and physical objects. ENTSO-E runs the scheme; codes are issued by its central issuing office and by local issuing offices.

What is the format of an EIC code?

Always 16 characters: two for the issuing office, one for the object type (for example Y for an area, X for a party), twelve for the identifier itself, padded with hyphens, and one check character at the end.

What does 10Y mean in an EIC code?

10 is the ENTSO-E central issuing office and Y means the code identifies an area, such as a bidding zone, control area or country. That is why almost all bidding zone codes start with 10Y.

What is the EIC code for Germany?

The German-Luxembourg bidding zone, used for day-ahead prices, is 10Y1001A1001A82H. Germany as a country or control area is 10Y1001A1001A83F. Mixing them up is a common reason an ENTSO-E query returns nothing.

Where can I find the EIC code of a company?

Codes of market parties (X codes) are in the list of approved EIC codes that ENTSO-E publishes on its website, and with the local issuing office of the country, usually the TSO.
