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 over half a million 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 office 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.

We’re experienced

Mayflower Wind draws from the deep experience and skills of its sponsor companies in successfully permitting, financing, constructing and operating offshore energy production facilities. Shell and Ocean Winds are willing and able players in the global energy transition, and see commercial opportunity in participating in the drive to provide more and cleaner energy solutions.
