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.
Work on the tunnel that will house the electrical interconnection between France and Spain was completed today, as the Spanish TBM Alberas pierced the final wall of rock to meet up with its French counterpart Canigou beneath the Pyrenees. The now fully excavated tunnel runs for 8.5 kilometres alongside the high-speed rail tunnel, between the villages of La Junquera in Spain and Montesquieu-des-Albères in France. It will act as the conduit for a 320,000-volt line, linking the French and Spanish power grids with minimal environmental impact. Learn more
