Prysmian Secures a Framework Agreement with RTE for Strategic Offshore Wind Farm Connections in France

Milan, 17th December 2024 – Prysmian has signed a Framework Agreement with Réseau de Transport d’Électricité (RTE), the French TSO, 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, specifically the “Fos Project” and the “Narbonnaise Project”, covering both submarine and land parts (including also landfall works).

The projects are subject to call off by RTE and finalization of the terms of the relevant EPCI contracts, which are expected to occur during the period 2026-2027. Delivery and commissioning are expected for the period 2031-2032. These two EPCI contracts are altogether estimated at a potential value of approximately € 700 million.

Each single project will consist of three High Voltage Alternating Current (HVAC) 225 kV three-core export cables with XLPE insulation, all equipped with synthetic armour. The approximately 400 km of land cables will be produced locally, in Gron, France, while the approximately 240 km of submarine cables will be manufactured at Prysmian’s centre of excellence in Arco Felice, Italy, and Pikkala, Finland, for a grand total of approx. 640 km of cables (land and submarine). Installation operation will be carried out using one of Prysmian’s proprietary advanced cable-laying vessels.

The Fos Project will be located on the coast of Provence-Alpes-Côte d’Azur and will require approx. 300 km of cables (land and submarine), while the Narbonnaise Project, located on the coast of Occitanie will require approx. 340 km of cables (land and submarine), providing individually a potential capacity of 750 MW.

These projects are of strategic importance as part of RTE’s long-term plan to develop the national power grid to accommodate new low-carbon facilities (both generation and consumption). Prysmian is already a leading supplier and installer of 200 kV submarine cable links in Europe and has established a strong relationship with RTE through previous projects such as the France-Spain (Bay of Biscay), France – UK (IFA2) and Italy-France (Piedmont-Savoy) interconnections. The development of offshore wind in France confirms Prysmian’s leadership in the sector, following the completed projects for submarine power cables in other offshore wind farms such as Fécamp, Calvados and Saint Nazaire and ongoing projects as Noirmoutier.
