Powering New England’s Energy Future

Mayflower Wind is developing a federal offshore lease area—located over 30 miles south of Martha’s Vineyard and 20 miles south of Nantucket—that has the potential to generate over 2,000 megawatts (MW) of low-cost clean energy, or enough to power nearly 800,000 homes. We expect to deliver clean energy from the project by the mid-2020s.

Questions? We have answers.

What is the overall project timeline?

We expect to deliver clean energy from the project by the mid-2020s.

Will fishermen be able to fish between offshore wind turbines?

Yes. Fishing activities will be allowed to continue as permitted in the project area, although some temporary exclusion zones are anticipated during construction and turbine installation due to the need to ensure safety for all mariners.  Mayflower Wind will continue to communicate with mariners in advance of construction and throughout the installation process.

How will this project affect my electric bill?

The Massachusetts Department of Energy Resources calculated that, over the life of the project Mayflower Wind will provide an average of 2.4 cents per kWh of savings to Massachusetts ratepayers (over $2 billion in savings). Due to newly enacted federal investment tax credits, customers of Massachusetts utilities can expect to save an additional half a billion dollars. Wind power stabilizes consumers’ electricity rates. Due to its lack of fuel cost, wind power protects consumers from volatility in the price of natural gas by offering a fixed low price over 20 years.

How does offshore wind contribute to reducing winter peak prices?

The strong and consistent wind speeds in the federal lease areas are projected to provide significant energy generation during all seasons of the year and hours of the day, with highest generation periods during the winter months when natural gas prices surge from heating demand.

A Committed and Experienced Team

The Mayflower Wind team prides themselves on being responsible and reliable environmental stewards. We are focused on using the best science and data to see the big picture as well as the small details that are critical to the success of our offshore wind energy project in the Commonwealth of Massachusetts. We are supported by the deep experience and skills of our sponsor companies, Shell and Ocean Winds, who successfully develop and operate offshore energy facilities in the U.S. and around the world. Together we are fully committed to providing clean energy solutions to our communities.
