The 132 kV Elba–Continente submarine cable interconnector between the Isola d’Elba (SE Colmata/Portoferraio) and Piombino in the province of Livorno entered into operational service in April 2023, following Terna’s approximately €90 million investment. The 37 km link, including 34 km offshore and 3 km of fully buried onshore cable installed using techniques such as horizontal directional drilling to minimise environmental impact, was commissioned to enhance the security and reliability of the island’s electricity supply and forms part of Italy’s strategic transmission infrastructure.
