Italy-France HVDC transmission line is latest to cross borders in European Union

The countries of the European Union are working together to transfer renewable energy across borders. The latest transmission link will be between Italy and France — traversing across the Alps.

The link is a partnership between seven different companies, the Prysmian Group and awarded by Terna Rete Italia S.p.A. and RTE, to connect the two countries through a €500 million High-Voltage Direct Current (HVDC).

“We are proud to make our technologies and our experience available to the realisation of a project with such a high strategic value” said Valerio Battista, Prysmian Group CEO. “The development of power transmission interconnections is of paramount importance in Europe. We are in the final stages of the HVDC interconnection between France and Spain that will start operations by the first half of 2015.”

The “Piemonte-Savoia” interconnection will be an underground HVDC cable, and will create an exchange between France and Italy of up to 1,200 megawatts (MW).

“The project comprises of a ± 320 kV extruded HVDC underground cable turnkey system that includes the engineering, production and installation of two 600 MW bipolar circuits along a 190 km land route between the substations of Piossasco, near Turin (Italy) and Grand’Ile in Savoy (France) with a total of approximately 95 km in each country,” Prysmian said in a statement.

The companies plan for the commissioning to take place in 2019.

The project is the latest transmission link in Europe, with two other projects currently underway. A 387-mile transmission line from Norway to Germany is current under construction, as well as a line connecting France and Spain.
