Deepwater ONE


Designed to serve Long Island and New England, Deepwater ONE is the nation’s first 1,000 MW-scale offshore regional energy center. In 2013, Deepwater Wind won from the U.S. government the exclusive right to develop the 256 square mile Deepwater ONE site. As the first of the “second generation” of offshore wind farms in the United States, it is larger, farther from shore, capable of producing cheaper electricity, and uses newer technology than offshore wind projects proposed in the United States to date. Deepwater ONE is planned as a 150-200 turbine project with an approximate nameplate capacity of 900-1,200 MW.

Deepwater Wind plans to sell the electricity generated from Deepwater ONE to Long Island and to New England states including Rhode Island, Massachusetts, and Connecticut. Deepwater Wind will pair Deepwater ONE with a new regional HVDC transmission system to deliver this clean, renewable energy to multiple markets. The New England-Long Island Interconnector (NELI) will for the first time link Long Island electrically to southern New England, increasing system reliability in both regions and enabling the delivery of utility-scale offshore wind power.

Deepwater ONE is located in the Atlantic Ocean on the Outer Continental Shelf 30 miles east of Montauk, New York and nearly 15 miles southwest of Martha’s Vineyard in Massachusetts. Most turbines will be located more than 20 miles from land. Deepwater ONE will produce enough electricity to power approximately 350,000 homes and displace over 1.7 million tons of carbon dioxide emissions annually, the equivalent of taking 4 million cars off of the road or 40 million barrels of foreign oil imports.
