Avangrid completes installation of Vineyard Wind 1 offshore substation in Massachusetts

Avangrid has completed the installation of the offshore substation at its 800 MW Vineyard Wind 1 offshore wind project located off the coast of Massachusetts, in the northeast of the USA. 

An offshore substation is a critical component of an offshore wind farm, designed and built to collect and export the electricity generated by the wind turbine generators. It serves as an intermediary platform between the wind turbine generators in the offshore lease area and the onshore power grid.

Including its two main components, the topside, and the jacket, the offshore substation weighs over 5,000 tons, making it the first one ever installed in the U.S. and the sixth and largest in the Iberdrola Group’s global fleet to date. So far, Iberdrola has installed five other substations at its West of Duddon Sands (UK), Wikinger (Germany), East Anglia One (UK), St. Brieuc (France), and Baltic Eagle (Germany) offshore wind farms.

Vineyard Wind 1 is expected to deliver the first power before the end of this year and, once completed, the facility will generate 806 MW of clean, renewable energy to power more than 400,000 homes and businesses in Massachusetts.
