Prysmian has secured a €300m contract from Réseau de Transport d'Électricité (RTE) to develop submarine cable links to connect three planned offshore windfarms to the mainland power grid in France.

Under the deal, Prysmian will design, supply, install, test, and commission two high-voltage (HV) export power cable links for Fécamp, Calvados and Saint Nazaire windfarms, covering both submarine and land routes.

This will be the first project for RTE where its cable links will be used to transmit renewable energy generated by offshore farms to businesses and homes.

Prysmian Energy Projects' SVP Massimo Battaini said: “We are proud to support RTE in this important challenge.

"The offshore wind market in France is a new and promising development in this segment."

“Prysmian is already widely involved in the provision of reliable and more sustainable power transmission connections in France, through the realisation of the France-Spain and the Italy-France interconnectors.

“The offshore wind market in France is a new and promising development in this segment and this contract not only consolidates our relationship with RTE but also re-affirms Prysmian’s world leadership in providing HV submarine cable solutions.”

The submarine cable links will feature high voltage alternating current (HVAC) 220kV three-core cables, with cross-linked polyethylene (XLPE) insulation and single wire armouring.

Prysmian is planning to use its own Cable Enterprise, a DP 2 vessel, for cable laying activities. The submarine cables will be manufactured at the Group’s centres of excellence in Italy and Finland. Cables for the land sections will be produced in France.
