The electricity interconnection between Gatika (Spain) and Cubnezais (France) will be the first fundamentally submarine interconnection between Spain and France.
This project will increase the exchange capacity from 2,800 to 5,000 MW, improving the safety, stability and quality of electricity supply between the two countries and also with the rest of Europe.
On the 1st of December, RTE officially submitted the applications for authorisation for the Biscay Gulf electricity interconnection project to the French authorities (Public Utility Declarations, Agreement for the Use of the Public Maritime Domain, Environmental Authorisation, etc.), 7 months after its counterpart, Red Electrica de España (REE), had done the same in Spain.Learn more
As part of the studies prior to the construction of the new interconnection between France and Spain via the Biscay Gulf, RTE and REE carried out geological studies of the seabed. They revealed ground instability along the edge of the Capbreton Canyon. Additional analyses conducted since June have not identified a route under the canyon that is guaranteed to be stable for the life of the power line.
RTE and REE are therefore forced to abandon this solution and define a new route around the canyon.
As part of the studies prior to the construction of the new interconnection between France and Spain via the Biscay Gulf, RTE and REE carried out extensive geological studies of the seabed. The latest studies, at the beginning of May, revealed soil instability very close to the Capbreton canyon, in French waters.
Inelfe organised a meeting with HVDC cable, converter station, submarine cable and drilling suppliers in Brussels. Held between 16 and 20 April, its goal was to explain the scope of the interconnection project between Spain and France via the Bay of Biscay and to exchange information on the best way to implement the project (technology, materials, implementation procedures, etc.).Learn more
