The Block Island Wind Farm, an installation of five GE Haliade 150-6 MW turbines, is the first commercial wind farm in the United States. Sighted 4.8 kilometers (~ 3 miles) southeast of Block Island, Rhode Island, power from the Block Island Wind Farm is transmitted to the electric grid along a 35.1 kilometer (~ 21.8 miles) transmission cable making landfall in Narragansett, Rhode Island.
A portion of the power is supplied directly to Block Island (located 25.7 kilometers offshore from the Rhode Island mainland), which has some of the highest electricity rates in the United States due to its local reliance upon small diesel generators. This five-turbine, 30 MW project was developed by Deepwater Wind, now known as Ørsted US Offshore Wind. The Gulf of Mexico, companies from Louisiana in particular, played a key role in the steel work construction, foundation design, and offshore assembly of the Block Island Wind Farm.
The Coastal Virginia Offshore Wind (CVOW) is an offshore wind energy project located 43 kilometers off the coast of Virginia Beach, Virginia. CVOW's initial project phase, utilizes two-turbines (Siemens Gamesa SWT-6 MW-152) in a 12 MW pilot project that completed construction in 2020. Dominion Energy and Ørsted US Offshore Wind collaborated in the CVOW pilot project, which is the second utility-scale offshore wind farm operating in the United States.
CVOW is the first utility-scale offshore wind farm constructed in US federal waters. The lease area covers 2,135 acres. Ultimately, CVOW's second phase is targeting a 2.6 GW offshore wind energy project that will consist of 176 wind turbines located 27 miles off the coast of Virginia Beach to power up to 660,000 homes.
