RTE (Réseau de Transport d'Électricité)

Réseau de Transport d’Electricite (RTE), the French transmission system operator, is expected to be responsible for the onshore grid connection works in France associated with the proposed Guernsey France One (GF1) HVDC interconnector. According to information reported from Guernsey Electricity’s project material, the land route in Normandy would be developed, permitted and installed by RTE. This scope covers designing and routing the onshore connection from the submarine cable landfall into the existing French transmission network, securing the necessary French-side permits, and carrying out or managing the civil works and cable/overhead line installation. GF1 is planned as a 100 kV, ~100 MW direct subsea cable between Guernsey and France that would significantly increase Guernsey’s import capacity of low‑carbon electricity. RTE’s role focuses on the French onshore section rather than the subsea cable itself and is part of early planning for the project rather than a formally awarded construction contract at this stage.
