ENTSO-E

ENTSO-E Member Companies

European Transmission System Operators (TSOs) are entities operating independently from the other electricity market players and are responsible for the bulk transmission of electric power on the main high voltage electric networks. TSOs provide grid access to the electricity market players (i.e. generating companies, traders, suppliers, distributors and directly connected customers) according to non-discriminatory and transparent rules. In order to ensure the security of supply, they also guarantee the safe operation and maintenance of the system. In many countries, TSOs are in charge of the development of the grid infrastructure too.

42 Members from 35 countries are part of ENTSO-E. TEIAS, the Turkish TSO, is an Observer Member since 2016. This Observer Membership is subject to renewal.
