Prysmian Group has completed the installation and HV testing activities at Vineyard Wind 1. Located more than 15 miles off the coast of Massachusetts, USA, Vineyard Wind consists of an array of 62 wind turbines that will generate 800MW of electricity.
The project was awarded to Prysmian Group in May 2019 by Vineyard Wind, LLC. The contract included the design, manufacture, installation and commissioning of an HVAC (High Voltage Alternating Current) cable system composed of two 220 kV three-core cables with extruded XLPE insulation. The 134-km submarine power cables were manufactured at Prysmian Group's facilities in Pikkala, Finland, and Arco Felice, Italy, while marine installation operations were performed by Prysmian Group's Cable Enterprise and Ulisse cable laying vessels.
