Hitachi Energy has been selected by Terna, the Italian transmission system operator, and EDF, to provide high-voltage direct current technology to increase the supply and improve the flow of electricity over the connection between Italy’s mainland grid and the islands of Corsica and Sardinia.

 The interconnection, named Sa.Co.I.3 will replace in full the existing equipment with advanced HVDC technology and increase the power capacity to 400 MW over a bipolar, multi-terminal scheme. The new connection is designed to make the electricity system more efficient, reliable, and sustainable for the two Mediterranean islands and Tuscany.

 Sa.Co.I.3 is part of the EU list of Projects of Common Interest (PCI), being of strategic importance for Europe and its islands.

Hitachi Energy will provide its HVDC Light solution, based on VSC (voltage source converter) technology. It is collaborating with Pellegrini and Razel-Bec to provide the civil and installation scope of the project. Multi-terminal HVDC systems, links with more than two converter stations, are in high demand as a key enabler to support the energy transition.
