Prysmian wins $167m contract for French offshore grid connection project


Italian multinational company Prysmian Group has won a $167m contract for the development of two submarine and land export power cable systems in France.

The power cable systems will export the green and renewable energy generated by a 500MW offshore wind farm located in between the islands of Yeu and Noirmoutier to the French mainland power grid.

Being developed by the company Les Eoliennes en Mer d’Ile d’Yeu et Noirmoutier, the offshore wind project was awarded by the French government.

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

Prysmian has secured the contract from the French transmission system operator RTE, which will be design, build, maintain and operate the two 225 kV links to connect the offshore wind farm to the grid.

Under the contract, the company will be responsible for the design, supply, installation, and commissioning of two HVAC 225 kV three-core extruded export submarine cables.

The cables will will reach the landfall area at La Barre-de-Monts beach.

Prysmian will also handle the supply and jointing of two HVAC 225 kV extruded land cables circuits, which will connect the landfall area to the substation at Soullans.

Prysmian will use Cable Enterprise to install cables

Cable Enterprise, one of the three company’s advanced cable laying vessels, will be used for the installation of cables.

Prysmian will produce submarine cables at its centres of excellence in Pikkala (Finland) and Arco Felice (Italy), while land cables will be manufactured in Gron (France).

The company is expected to deliver and commission the cables in 2023, depending upon the receipt of the notice to proceed expected by March 2020.

The others key projects in France where Prysmian is involved include Fécamp, Courseulles-sur-Mer and St. Nazaire offshore wind farms and the Provence Grand Large floating offshore wind farm (awarded by EDF Renewables).

In addition, the company has secured contracts for the IFA2 interconnection linking the UK and France, the Piedmont-Savoy interconnection between Italy and France, and the INELFE interconnection linking Spain (Santa Llogaia) and France (Baixas).
