Balancing the electricity supply system
The role of RTE is to manage flows and ensure that supply balances demand.
As the Group's transmission grid operator, RTE guides electricity flows by managing 100,000 km of high-voltage and very high-voltage circuits to optimise the supply of power
RTE carries electricity from generating plants to major industrial facilities and the distribution grids that supply consumers
RTE also acts as the interconnector with the power grids of neighbouring countries through 46 cross-border power lines, contributing to overall security of supply and efficient operation of the European power supply system
Transmission engineering services and the operation of non-RTE electricity systems are coordinated by the Transmission System Engineering Centre (CIST). In mainland France, CIST manages grid connections and their associated facilities. There expertise is also recognized internationally, and they are currently present in 33 countries, engineering EDF transmission networks and assisting clients with their optimisation problems and developing their electricity grids.
