The northern frontier

On the northern frontier, one of the key development projects is the continuous current interconnection with France, linking the hubs at Piossasco (Turin) with Grand’Ile (France) via a terrestrial continuous current cable, either underground or integrated into the infrastructure of the A32 Fréjus motorway. The presence of long tunnels and viaducts makes this highly ecological project the only one of its kind in the world. Authorised by the Italian authorities in March 2011, the line will be 190 km long. Half of that length will be in Italy, and it will use the motorway platform and new service link through the Fréjus tunnel.

The new link, which will guarantee an increased capacity for exchange with the French frontier, will also augment the supply of cheap energy and the diversification of primary sources, which will have benefits for the country as a whole.
