Prysmian Group has secured two offshore wind cabling projects in the US for a total of approximately USD 880 million (EUR 782 million).

Both projects have been awarded by Vineyard Wind, a joint venture between Avangrid Renewables and Copenhagen Infrastructure Partners (CIP).

The first cabling project will connect the 804 MW Park City offshore wind farm to the electricity grid in the state of Connecticut.

Prysmian will deploy HVAC 275 kV three-core cables with XLPE insulation and single wire armouring. Cables will be produced in the Group’s centres of excellence Arco Felice, Italy, and Pikkala, Finland, and will be installed by the Leonardo da Vinci and Ulisse vessels. Delivery and commissioning are scheduled for 2026. The value of this contract is around USD 300 million.

The Commonwealth Wind cabling project is worth around USD 580 million. Prysmian’s award follows the Massachusetts Baker-Polito administration selection of the Vineyard Wind’s proposal for delivering 1,200 MW of offshore wind farm capacity.

Prysmian will design, supply, install, and commission as many as three export submarine power cable links to connect the Commonwealth Wind to the electricity grid in Massachusetts. Prysmian will supply HVAC 275 kV three-core cables with XLPE insulation and single-wire armouring.

Cable Manufacturing Plant at Brayton Point

As part of the Commonwealth Wind project agreement and subject to several customary conditions precedent, such as obtaining permits to build the facilities and closing the contractual arrangements with the property owner, Prysmian intends to build a manufacturing facility for submarine transmission cables at Brayton Point, the site of the former 1,600 MW coal-fired power plant in Somerset.

Both cable supply awards are subject to the finalization of Prysmian Group plans to localize its footprint.

The submarine cables for Commonwealth Wind are planned to be produced in the new plant in Massachusetts, as well as in Arco Felice and Pikkala. Cables will be installed by the Leonardo da Vinci and Ulisse vessels. Delivery and commissioning of the export cables are scheduled for 2027.

”The renewed partnership with Avangrid confirms the validity of Prysmian’s growth ambition in the fast-developing offshore wind farm industry in the US. Prysmian is also excited to announce significant progress towards its first submarine power cables manufacturing facility in the US,” said Hakan Ozmen, Executive VP at Prysmian Group.

”While we still have work to do to finalise the agreement, it is clear that, with the support of the state of Massachusetts and others, we are in a great position to reach a final agreement that will prompt a major expansion of our Company.”

Prysmian has previously won contracts to provide cable systems for the 804 Vineyard Wind 1 project and the 2.6 GW Coastal Virginia Offshore Wind project.
