Danish power cable manufacturer and installation firm NKT has completed two of the three landfalls in France for this country’s first submarine electricity interconnection to Spain.

Delivered by Inelfe, a joint venture between the Spanish transmission system operator (TSO) Red Eléctrica and the French counterpart Réseau de transport d’électricité (RTE), the Biscay Gulf Interconnector will have a total route length of 400 kilometers, of which 300 kilometers is underwater, connecting Cubnezais in France and Gatika in Spain.
