Vineyard Wind 1 is an 806MW project located 15 miles (24km) offshore Martha’s Vineyard. It is being built with an investment of $2.3bn.

The wind farm will be powered by 62 GE Haliade-X turbines, each with 13MW of power generating capacity.

It will generate enough clean electricity for 400,000 Massachusetts households, while avoiding 1.6 million tonnes of carbon emissions annually.

Onsite construction on the project began in late 2021. The offshore substation was installed in July 2023.

In October 2023, the first turbine at the wind farm site was installed. This single turbine can generate enough clean power to supply 6,000 homes.
