Description
Prysmian Group was awarded a turnkey contract by Red Eléctrica de España to deliver the submarine and associated land cable system for the Tenerife–La Gomera 66 kV AC interconnection. The scope covers the design, manufacture, installation and commissioning of a double‑circuit, three‑core HVAC submarine power cable system running between the new Chío substation in Tenerife and the El Palmar substation in La Gomera, including the underground land sections at both ends. Prysmian is responsible for engineering the world‑record‑depth 66 kV three‑core cable, producing the subsea cables in its Norderham and Pikkala plants and the land cables in Vilanova, and performing marine installation with its own cable‑laying vessel, as well as land cable installation and terminations. The contract forms part of Red Eléctrica’s programme to strengthen the Canary Islands’ grid and enable higher renewable integration on La Gomera and Tenerife.
