Prysmian to Connect French Offshore Wind Farm

Prysmian Group has secured a contract by Réseau de Transport d’Électricité (RTE) to develop two submarine and land export cable systems for the Iles d’Yeu et de Noirmoutier offshore wind farm in France.

Under the contract worth more than EUR 150 million, Prysmian will provide the design, supply, installation, and commissioning of two HVAC 225kV three-core extruded export submarine cables with single-wire armoring which will reach the landfall area at La Barre-de-Monts beach.

The company is also responsible for the supply and jointing of two HVAC 225kV extruded land cables circuits that will link the landfall area to the substation at Soullans.

Submarine cables will be produced at Prysmian’s centers of excellence in Pikkala, Finland, and Arco Felice, Italy, while land cables will be manufactured in Gron, France.

Cable laying vessel Cable Enterprise will perform the installation operations. Delivery and commissioning are scheduled for 2023.

RTE will design, build, maintain and operate the two 225kV links to connect the 500MW offshore wind farm to the grid.

The offshore wind grid connection project will cover a submarine cable route of around 27km and an underground cable route of around 30km.

Prysmian has also worked with RTE on the Fécamp, Courseulles-sur-Mer and Saint Nazaire offshore wind farms and the Provence Grand Large floating offshore wind farm.
