Project Description

Mayflower Wind is developing an offshore lease area with the potential to generate over 2,400 megawatts (MW), or enough to power over 800,000 homes.

The lease area is located over 30 miles south of Martha’s Vineyard and 20 miles south of Nantucket.  

The project will occupy the 199-square mile (or over 127,000 acre) lease area, which was awarded through a competitive auction by the US Bureau of Ocean Energy Management. 

By pursuing dual grid connection points – delivering 1,200 MW to Brayton Point/Somerset and 1,200 MW to Falmouth – Mayflower Wind can maximize the potential of the offshore lease area’s generation capacity.

Mayflower Wind will deliver the 1,200 MW awarded through Massachusetts’ Section 83C II and III offshore wind energy procurements ashore via a grid connection at Brayton Point/Somerset. 

Delivery of the next 1,200 MW to the Falmouth grid connection would occur in a subsequent phase. 

Electricity customers of distribution companies from across the Commonwealth will benefit from Mayflower Wind’s clean energy resource as the power will contribute to the decarbonatization of the electrical grid. Eversource is the incumbent utility for Falmouth and Cape Cod, as well as for New Bedford and much of the SouthCoast – though Somerset and Fall River are located in National Grid’s service territory.  

We are currently focused on conducting baseline surveys, stakeholder outreach, and other activities that advance the initial design, engineering, and permitting of the project. The project will require local, regional, state, and federal permits and approvals for relevant onshore, nearshore, and offshore work.

These efforts have been, and will continue to be, pursued with input from local communities to ensure a safe, reliable, and responsible project that meets the expectations of Massachusetts ratepayers and makes the SouthCoast region a hub for offshore wind.

The work we are doing on the SouthCoast is convergent with our ongoing work in Falmouth.

Mayflower Wind stands ready to bring Massachusetts’ clean energy goals to reality while supporting the people and communities who help bring the benefits of renewable offshore wind energy to our shorelines.
