HVDC Cables Along with Highway Infrastructures: the “Piedmont-Savoy” Italy-France Intertie

The rationalization of territory resources draws the scientific society attention to the possibilities given by the highway and railway infrastructures (planned or existing) in order to install high voltage direct/alternate current insulated cables. The full compatibility of such synergy “highway/railway transport-electric energy transmission” involves different engineering branches. This topic has been investigated in the last ten years by means of feasibility studies published in scientific papers and technical brochures. These studies have eventually found a real and important application in the future ±320 kV High Voltage Direct Current interconnection between France and Italy named “Piedmont-Savoy” which will constitute a further strengthening of the Pan-European grid.
