We are a global operator of essential infrastructure
The new electrical interconnection line between Spain and France has a length of 64.5 kilometres, 33.5 in France and 31 in Spain. It connects the towns of Baixas, in the Roussillon region (France), and Santa Llogaia, in Alto Ampurdán (Spain).
The central part of the line will cross the Pyrenees at the Albera massif. An 8.5-kilometre tunnel will be built for this section, one kilometre in Spain and 7.5 kilometres in France. The rest of the line will be in underground trenches.
The new electrical interconnection between Spain and France is a necessary infrastructure which will allow:
- Doubling the exchange capacity between Spain and France.
- Making the most of electricity from renewable sources.
- Assuring security of supply for the inhabitants of the Ampurdán and Roussillon.
- Integrating the Iberian market into the European electricity market.
- Promoting economic development in the area.
- A feed for the high-speed train.
