The Sunrise Wind energy project should be reduced in size to protect cod habitat off southern New England and avoid areas where seafloor geology will make it difficult to build wind turbine foundations, a newly completed environmental assessment concludes. Project partners Ørsted and Eversource originally proposed up to 94 turbines on an 86,823-acre lease 16.4 nautical miles south of Martha's Vineyard, Mass., and 26.5 nautical miles east of Montauk, N.Y. The latest preferred alternative affirmed by the federal Bureau of Ocean Energy Management would reduce the number of turbines to 84 machines, "to accommodate geotechnical feasibility of the project, reduce impacts to benthic habitat and Atlantic cod, and meet the energy needs of New York, Massachusetts and Rhode Island," the agency said Monday.
