ETSO is governed by a council representing the four founding associations and by a steering committee, in which each of the member countries is represented.
TSOs are responsible for the bulk transmission of electric power on the main high voltage electric networks. They provide grid access to the electricity market players (generating companies, traders, suppliers and customers) according to non-discriminatory and transparent rules, and ensure the safe operation and maintenance of the system. In many countries, they are also in charge of the planning and development of the grid infrastructure.
