Prysmian has signed a framework agreement with Réseau de Transport d’Électricité (RTE), the French transmission system operator, for the engineering, procurement, construction, installation, and commissioning (EPCI) of submarine power cable links. These links will connect two offshore wind farms to the French transmission grid: the "Fos Project" and the "Narbonnaise Project," covering both submarine and land components, including landfall works.
The projects are subject to call-off by RTE and the finalisation of the terms of the relevant EPCI contracts, expected during the period 2026-2027. Delivery and commissioning are anticipated for 2031-2032.
Each project will consist of three high voltage alternating current (HVAC) 225 kV three-core export cables with XLPE insulation, all equipped with synthetic armour. Approximately 400 km of land cables will be produced locally in Gron, France, while about 240 km of submarine cables will be manufactured at Prysmian’s facilities in Arco Felice, Italy, and Pikkala, Finland, totalling approximately 640 km of cables. Installation will be carried out using one of Prysmian’s cable-laying vessels.
The Fos Project, located on the coast of Provence-Alpes-Côte d’Azur, will require approximately 300 km of cables (land and submarine). The Narbonnaise Project, located on the coast of Occitanie, will require about 340 km of cables (land and submarine). Each project will provide a potential capacity of 750 MW.
