The European Network of Transmission System Operators for Electricity is an association of 43 transmission system operators in 36 European countries, both EU members and non-members. The ENTSO-E was established and its responsibilities and relations to other EU institutions defined in accordance with EU legislation – the 3rd Energy Liberalisation Package.
The completion and smooth functioning of the internal market and cross-border electricity trading make up the major objectives of ENTSO-E together with ensuring the optimum management and further development of European electricity transmission systems in line with the coordinated cooperation of transmission system operators. One of the most important ENTSO-E activities concerns the development and implementation of network codes, legally binding EU legislation.
ENTSO-E is governed by its General Assembly and the work of the organisation is coordinated by the ENTSO-E Board.
Pan-European issues concerning transmission system operators are discussed by four committees:
- the System Development Committee,
- the System Operations Committee,
- the Market Committee;
- the Research & Development Committee
and the Legal and Regulatory Group.
Expert groups are established on an ad hoc basis.
Futhermore, regional sub-groups deal with TSO issues related to synchronous zones (ČEPS is part of the Continental European synchronous zone) and defined network development in terms of both geographical and market areas.
