A high voltage direct current (HVDC) underground cable system interconnecting France and Spain has been inaugurated into commercial operation.
The €90m ($101m) INELFE project was undertaken by Italian cable company Prysmian on behalf of Spanish grid operator Red Electrica de España (REE) and its French counterpart Réseau de Transport d’Électricité (RTE).
The project comprised a 320kV extruded HVDC underground cable and two 1000 MW bipolar circuits along a 64 km land route, with 8.6 km in a purpose-built tunnel across the Pyrenees.
The project links substations in Baixas, near Perpignan in France, and Santa Llogaia, near Figueres in Spain. The cables were manufactured at Prysmian facility in Gron in France.
Prysmian said INELFE was classified as a priority project by the EU and was intended to “substantially increase the transmission capacity between France and Spain, thus improving diversification of sources and security of supply, as well as enhancing electricity market integration in South-West Europe”.
