PROVIDENCE, R.I. (AP) — Construction on the nation's first offshore wind farm has finished.
Deepwater Wind built a five-turbine wind farm off Block Island, Rhode Island.
Deepwater Wind CEO Jeffrey Grybowski tweeted a photo of the five turbines on Thursday. He says the wind farm is now fully constructed.
The final blade for the fifth turbine was installed Thursday.
The wind farm is expected to be operational this fall after testing is complete. The $300 million project is expected to power about 17,000 homes.
Developers, federal regulators and industry experts say the opening will pave the way for many more wind farms that eventually will provide power for many more Americans.
Grybowski says the wind farm's opening will be a "momentous occasion."
