Work underway on first US offshore wind farm

Construction has begun on the first commercial-scale offshore wind farm in the United States, three miles off the coast of Rhode Island. Although small in size when compared to the massive offshore wind farms that have been going up in European waters, the new wind farm off Block Island will consist of five Haliade turbines. These have a 6MW capacity and a 150-metre diameter rotor, which manufacturer Alstom claims offers a 15% better energy yield than existing offshore turbines, enabling each one to supply power to the equivalent of 5,000 households. The wind farm will be operating by autumn 2016.

Deepwater Wind, the company behind the project, expects the wind farm to cut energy bills for the island – home to some of the highest rates in the country – by 40%. The farm will produce more energy than the island needs, enough for 17,000 homes, and surplus energy will be used on the mainland. 

While a vocal minority complains that the farm will spoil their ocean view, the majority of residents are in favour of the project, including state and local leaders, environmentalists, fishermen and a local Indian tribe.

However, other wind farm projects have stalled because of lawsuits, regulatory troubles and a lack of local support. For example, Cape Wind’s proposed 130-turbine wind farm was for years expected to be America’s first such project, but, after 14 years and millions of dollars spent working through the regulatory hurdles and fighting lawsuits, it may never be built.
