Inelfe is the company that has built and launched the new connection between Spain and France, operational since 2015, with the aim of increasing the volume of electric energy exchange between the Iberian Peninsula and the rest of Europe. The company was born as a result of the Zaragoza agreement, signed on June 27, 2008, between the Spanish and French governments.
The connection has allowed for the doubling of the connection level between France and Spain, from 1,400 MW prior to its construction to 2,800 MW, so the level of exchange is a bit closer to the 10,000 MW recommended by the EU.
The new line is 64.5 kilometers long and links the municipalities of Santa Llogaia (near Figueres in Spain) and Baixas (near Perpignan, in France.) Following the recommendations of the construction project mediator, Mario Monti, the layout is buried. The stretch that passes through the Pyrenees is 8.5 kilometers long, and has been overcome with a tunnel, while the rest of the line is buried in ditches.
Due to its length and its special features, the link uses direct instead of alternating current, like the rest of the Spanish and French electricity networks. Two converter stations were built for this reason, in Santa Llogaia and Baixas, in charge of transforming DC power into AC and vice versa. These converter stations use VSC (Voltage Source Converter) technology, an innovation that allows for the speeding up of the current direction reversal.
The construction of the connection had a budget of 700 million euros and was declared a European interest project. It was funded by the EU through the EEPR program (European Energy Program for Recovery) and by the European Investment Bank (EIB.)
