The project replaced noisy diesel generators with five offshore wind turbines that now power the entire island of Block Island, Rhode Island, plus 12,500 mainland homes.
Almost 20 years ago the first Wind Farm of 16 wind turbines was built off Block Island. What were the effects, was the decision worthwhile? A tour bus spills a few dozen people at its usual
When wind is not blowing, and to access cheaper sources than the wind farm, Block Island buys power from the grid along with carbon offsets. Starting in November 2025, it will source only 100%
Green Island currently relies on a mix of traditional fossil fuel-based power generation and limited renewable sources. The existing infrastructure faces several challenges:
Wind speed tends to increase with altitude, and the taller the tower is, the larger the blades and the turbine can be, dramatically increasing energy production.
By some estimates, the region will need 30,000 megawatts of offshore wind power by mid-century — that''s roughly the amount of electricity that can currently be produced by all of the
The cost of wind power was less than a third of that of diesel power. The underwater cables connecting the turbines to the mainland grid also provided much-needed broadband internet
Due to the intermittent nature of wind, turbines produce more power during high winds, and less during low winds. When the turbines make more electricity than needed by customers, the
Today, as the leading offshore wind energy company in the U.S., we''re building offshore wind projects spanning the East Coast from Rhode Island down to Maryland. Combined, they''ll have a generating
This offshore wind farm serves to provide power to the relatively tiny population (>2000 p.) of the Block Island community and Block Island resorts, part of Rhode Island.
OverviewOperationDesign and capacityPermits and fundingConstruction
During a major winter storm in March 2017, the turbines functioned as designed, automatically cutting out when the wind speed reached 55 mph (25 m/s). After the wind speed had topped out at about 69 mph (31 m/s), they resumed production again once the speed went below the cut-off threshold. The project also provided jobs for the state of Rhode Island, employing welders, workers during assembly of the wind turbines, and divers.
