RTE (Réseau de Transport d'Électricité)

RTE (Réseau de Transport d’Électricité) is the electricity transmission system operator of France and a public utility responsible for operating, maintaining and developing the national high- and extra-high-voltage grid. Created in 2000 and organised as a société anonyme with an executive board and oversight council, it is indirectly owned through the holding company CTE, whose shareholders are EDF, Caisse des Dépôts et Consignations and CNP Assurances. RTE is certified as an independent transmission operator and its governance, code of conduct and compliance function are designed to ensure autonomy, neutrality and non‑discriminatory access to the transmission network. It forms part of the European Network of Transmission System Operators for Electricity (ENTSO‑E). RTE’s core mission is to guarantee electricity supply across metropolitan France by managing power flows and balancing supply and demand in real time, 24/7. The company operates, renews and expands a transmission network of about 106,550 km of lines at voltages from 63 kV to 400 kV, combining overhead, underground and submarine circuits and several dozen cross‑border interconnections that link France to neighbouring European systems. It plans grid development through ten‑year network development plans and regional renewable connection schemes, and provides extensive public data and forward studies on consumption, generation, cross‑border exchanges and system adequacy. In 2024 RTE reported revenue of around €5.6 billion and a net profit of €171 million, and employed on the order of 10,000 people. Strategically, RTE is investing heavily to support France’s energy transition, including a programme to increase interconnection capacity with other countries and to connect offshore wind farms and other low‑carbon generation to the grid. It issues green bonds whose proceeds are dedicated to projects such as new interconnectors and offshore wind connections, explicitly excluding nuclear and fossil‑fuel facilities. The company holds ISO 14001 environmental certification and implements biodiversity and habitat‑enhancement measures along transmission corridors in partnership with conservation organisations, alongside broader climate and sustainability commitments embedded in its public‑service contract with the French state.
