VINALHAVEN — A consultant hired by the Maine Department of Environmental Protection says wind turbines installed on Vinalhaven island exceed state noise standards.

Some neighbors have expressed frustration over the nighttime noise levels, and the consultant agreed that the three turbines exceed the 45-decibel limit.

Fox Island Wind was dedicated in November 2009 with a goal of easing electricity rates for residents of Vinalhaven and North Haven islands. But some residents complained about the noise, especially at night. The consultant, Warren Brown, said “substantial changes” are recommended for nighttime operations,

Fox Island Wind has insisted that it meets state guidelines. CEO George Baker could not be reached immediately for comment on Monday.
