On 30 September 2025, Eiffage, through its subsidiary Smulders, was awarded a contract by French TSO RTE to develop and build three alternating current offshore substations in France, serving the Bretagne Sud, Narbonnaise Sud-Hérault and Golfe de Fos offshore wind farms. This award makes Eiffage/Smulders the substation supplier for the Narbonnaise Sud-Hérault project’s AC platform, which forms part of RTE’s grid connection infrastructure in the Mediterranean.
On 17 December 2024, Prysmian signed a Framework Agreement with French transmission system operator RTE to provide the engineering, procurement, construction, installation and commissioning of the submarine and land power cable links for the Fos and Narbonnaise offshore wind projects, including the Narbonnaise grid connection. For Narbonnaise, the scope covers approximately 340 km of combined land and submarine 225 kV HVAC three-core export cables and associated landfall works, with the specific EPCI contracts to be called off and finalised by RTE in 2026–2027 and delivery and commissioning targeted for 2031–2032.
