Up to 5,000 MW
INCREASE EXCHANGE CAPACITY
LENGTH OF THE INTERCONNECTION
TWO PER LINK
2 x 1,000 MW
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, increasing the safety, stability and quality of electricity supply between the two countries and also with the rest of Europe.
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.
