Cape Wind was granted a long-awaited permit today from the U.S. Army Corps of Engineers that it needs to start construction of 130 turbines in Nantucket Sound.
The permit to conduct work in navigable waters was expected, but its delay was cited by the company as one obstacle to obtaining a lucrative federal grant for the project last year.
The wind farm, expected to start construction this year, is still waiting for a U.S. Environmental Protection Agency permit for air pollution during construction.
"We are very pleased," said Cape Wind spokesman Mark Rodgers. "It is more forward momentum."
