A power output the equivalent of around three nuclear plants is to be shared between France and Spain.
The link to carry energy across the Pyrenees mountains was launched on Friday in a joint project by RTE, a unit of French utility giant EDF and Spain’s Red Electrica. It will double French-Spanish interconnection capacity to 2,800 megawatts.
The power line is one of the European Union’s Projects of Common Interest which benefit more than one EU nation and are entitled to EU funding and fast-tracked planning procedures.
It received 255 million euros in EU support towards the 700 million euro cost of the cable buried beneath the Pyrenees.
