Prysmian Group has been awarded two contracts worth approximately €250 million by Red Eléctrica (Red Eléctrica de España, S.A.U.), the Transmission System Operator of the Spanish power grid.


It concerns the development of two projects, a submarine power interconnection between the islands of Tenerife and La Gomera, and another submarine power interconnection between the Spanish mainland and Ceuta (a Spanish city on the north coast of Africa). 
 
Prysmian will provide its turnkey approach for the design, supply, installation, and commissioning of a 66 kV HVAC(High Voltage Alternating Current)  double circuit, three-core submarine power cable with EPR insulation and synthetic-wire armouring, to connect Tenerife and La Gomera a depth of nearly 1150m for a 66 kV three-core cable. It will also deliver a 132 kV HVAC doble circuit, three-core submarine power cable with XLPE insulation and synthetic-wire armouring, to connect the Spanish mainland and Ceuta  through the Strait of Gibraltar with maximum depths of 900 metres. Both systems comprise 90 km of submarine route and approximately 11 km of land route for the double link between Spanish mainland and Ceuta. 
 
The submarine cables will be manufactured in Norderham Plant (Germany) and Pikkala Plant (Finland). The land cables will be produced in the Group’s local plant of Vilanova (Spain). Marine operations will be performed with one of Prysmian’s own cable-laying vessels,
Giulio Verne. The commissioning of both cable systems is scheduled for 2025. 
 
“This award confirms the mutual trust and long-standing relationship between Red Eléctrica and Prysmian Group, because it is the latest of several projects developed together in Spain to enhance the national power grid’s reliability. We are proud to support Spain in meeting its Energy Transition goals by 2030, providing our state-of-the-art submarine and land cable systems,” stated Hakan Ozmen, EVP Projects BU, Prysmian Group.
