Electricity interconnexion Baixas (Eastern Pyrénées) – Santa LLogia (Catalonia)

The French and Spanish electric interconnection was inaugurated in February 2015 in Montesquieu-des-Albères in Eastern Pyrénées. The interconnection is 64km long and brings 320,000 volts. The high-voltage line ensures the electric supply between the two countries. It also promotes renewable energy.

The high-voltage line connects both municipalities of Santa Llogia (Catalonia) and Baixas (Eastern Pyrénées) and is entirely underground. It doubles the electric interconnection level between France and Spain from 1,400MW to 2,800MW. The underground connection is a unique project in the world because it is the first electric connection using the new technology of conversion station (transforming alternating current into direct current). The project promotes sustainable energy with 181 environmental promises and 1 million tons of CO2 saved using renewable energies.

The project was built in three years with 700 millions € invested. The Iberian Peninsula is now connected with the whole European electric system.
