GF1 is Guernsey Electricity's project to install a subsea cable directly from France to Guernsey.
The Guernsey France One (GF1) project is led by Guernsey Electricity Ltd. The cable is likely to be specified as a 100kV, a new substation in Guernsey, and connections into the electricity grids at each end.
The project is being jointly developed by Guernsey Electricity and Réseau de Transport d'Electricite (RTE). The land route in France will be developed, permitted and installed by RTE.
The approximate length of the marine cable will be 57 km. The entire route will total approximately 84.5km, between the electrical substation at Tollevast on the Cotentin peninsula in France, and Guernsey.
