Plans to build an 800-MW offshore wind farm off the Massachusetts coast near Martha’s Vineyard advanced on Aug. 1 when developer Vineyard Wind announced power contract deals with three major state utilities that set a levelized price of 6.5¢ per kW/hr.
Utilities Unitil, National Grid and Eversource Energy on June 29 issued a request for proposals for 400 MW of Massachusetts offshore wind generation, but up to 800 MW will be allowed if the utilities can demonstrate significantly more economic benefit.
