Mayflower Wind is a joint venture project of Shell and EDP Renewables. We are backed by the combined capability, experience, commitment to innovation, and financial strength of a world-leading offshore energy developer and a world-leading wind power and renewable energy developer.

At Mayflower Wind, we are committed to safety first and safety always, innovation and industry development, and investing in our local communities.


In September 2019, Mayflower Wind submitted two bids into the state of Connecticut offshore wind development procurement process. Mayflower Wind submitted an 800 megawatt (MW) proposal as well as a 400 MW proposal. The two bids can be found here:

Mayflower Wind CT Project 1 – 804 MW

Mayflower Wind CT Project 2 – 408 MW

In August 2019, Mayflower Wind submitted four bids into the Commonwealth of Massachusetts’ second round of the Section 83C offshore wind development procurement process. Mayflower Wind submitted three 800 megawatt (MW) proposals as well as a 400 MW proposal to the Massachusetts electric utilities. Public versions of the bids can be found here:

Mayflower Wind MA Project 1 – 408 MW

Mayflower Wind MA Project 2 – 804 MW Low Cost Energy

Mayflower Wind MA Project 3 – 804 MW Infrastructure and Innovation

Mayflower Wind MA Project 4 – 804 MW Massachusetts Manufacturing

In December 2018, Mayflower Wind won the rights
to develop a lease area that can support up to 1,600 megawatts of offshore wind over 20 miles south of Martha’s Vineyard.

That’s enough to power 680,000 New England homes.

We expect energy to be delivered as early as the mid-2020s. 


  • Wind power from the project is expected to eliminate 2.5 million metric tons of greenhouse gas emissions annually once in operations—the equivalent of taking 5.3 million cars off the road

  • Future cost savings for New England electric customers as offshore wind prices continue to come down rapidly

  • Unique capability to train up generations of future New England offshore workers for good-paying, innovative wind-industry jobs, leveraging Shell's 40+ years of operating in the Gulf of Mexico and North Sea and EDP Renewables' experience as the world's 4th-biggest wind energy producer

  • Offshore wind manufacturing and supply chain development represents thousands of new jobs across the Northeastern U.S., including Massachusetts

  • $135 million lease payment to the U.S. government



Safety is a core value for Mayflower Wind: Safety of people working on and around our project, safety of the environment and wildlife, safety in every way. Our aim is to lead the U.S. offshore wind industry in setting and continually raising the standards for safety and operations.

We are committed to leveraging data as well as the latest innovative technologies and techniques to ensure the safety of our people, community members, wildlife, and the environment.


Mayflower Wind prides itself on being a responsible and reliable environmental steward. That means minimizing harm and potential impacts to the environment. We are continually 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 project, our neighbors, and our region.

We will conduct extensive surveys, produce a detailed Environmental Impact Statement, and work collaboratively with local partners to understand their concerns and use their feedback to ensure that we construct the wind farm with as few impacts as possible.
