Sa.Co.I.3 ±200 kV HVDC multi-terminal interconnector between Suvereto (mainland Italy), Lucciana (Corsica) and Codrongianos (Sardinia), comprising two parallel subsea cables with a total subsea route length of about 121 km, replacing the existing SACOI2 link.
Prysmian reported that it has "already secured" the Sa.Co.I.3 HVDC submarine connection project with Terna, alongside other major Italian interconnector schemes. This implies a role supplying and installing the subsea cable system for the new 200 kV, 400 MW Sa.Co.I.3 interconnector linking Sardinia, Corsica and mainland Italy, replacing the existing Sa.Co.I.2 link. The contract is part of a portfolio of submarine connection projects that Prysmian is delivering for Terna, although specific contract value, award date and exact cable lengths for Sa.Co.I.3 were not disclosed in the available sources.
