Developer Deepwater Wind has now received permits and approvals for the project, which is located five kilometres off the coast of Block Island, in Rhode Island, northeast USA, from nine state and federal agencies.
It is still waiting on the Bureau of Ocean Energy Management (Boem) to review the application for right-of-way in federal waters for the site's transmission cable. A decision is expected in the coming weeks.
Block Island is set to be one of the first commercial offshore projects in the US when it is commissioned, planned for 2016.
Alstom's 6MW Haliade has been selected for the five-turbine project and the US developer has already received the 15 blades, which will be used.
Deepwater intends to use the project to provide a test case for an offshore wind farm of up to 200 turbines in Rhode Island federal waters.
