Nation’s First Offshore Wind Farm Puts “Steel in the Water” off Rhode Island Coast
As part of President Obama’s Climate Action Plan, U.S. Secretary of the Interior Sally Jewell and Bureau of Ocean Energy Management (BOEM) Director Abigail Ross Hopper recently joined Rhode Island Governor Gina M. Raimondo and Deepwater Wind, the project developers, in celebrating America’s first commercial-scale offshore wind farm. Deepwater Wind is constructing a five-turbine, 30-megawatt wind farm in state waters about three nautical miles southeast of Block Island. At 589 ft above sea level, the turbines will be among the tallest in the world.
The project, scheduled to be online in 2016, is expected to power about 17,000 homes. The facility will provide electricity directly from the wind farm to Block Island. Because the island uses only 1 megawatt of power in the off-season and 4 megawatts in the summer peak season, the remaining 90% of the energy produced during the off-season will be sent to other state customers via a 25-mile bi-directional submerged transmission cable between Block Island and the Rhode Island mainland.
The wind farm will produce more than 100 million kilowatt hours of clean energy annually, and Deepwater Wind will sell the electricity through a Power Purchase Agreement to National Grid, a Rhode Island utility. Project developers estimate the wind farm will reduce electric costs by 40% for the average ratepayer on Block Island, which currently relies on expensive diesel-powered generators. With the transmission line, Block Island has no need for backup diesel generators, as it can purchase electricity from National Grid once the cable is laid.
Because the project will be sited in state waters, the U.S. Army Corps of Engineers was the lead federal agency for analyzing the potential environmental effects of the project under the National Environmental Policy Act (NEPA). In addition to issuing the right-of-way grant, BOEM was a cooperating agency in the NEPA analysis and associated consultations led by the Corps.
“Interior is proud to be a partner in this historic milestone for offshore renewable energy,” Jewell said. “Deepwater Wind and Rhode Island officials have demonstrated what can be accomplished through a forward-looking vision and good working partnerships. Block Island Wind Farm will not only tap into the enormous power of the Atlantic’s coastal winds to provide reliable, affordable, and clean energy to Rhode Islanders, but will also serve as a beacon for America’s sustainable energy future.”
“As the Nation’s pioneering offshore commercial wind farm, the lessons learned from the Block Island project about facility design, fabrication and installation will inform future projects to be developed on the Outer Continental Shelf,” said Hopper. “This is an exciting development for Block Island and also demonstrates the way forward for wind energy in federal waters off America’s coasts.”
The celebration included a boat tour of the project site to provide a close look at the turbine foundation work underway. Also participating in the celebration were Rhode Island’s U.S. Senators Jack Reed and Sheldon Whitehouse and U.S. Representatives Jim Langevin and David Cicilline; Deepwater Wind’s CEO, Jeffrey Grybowski; members of the state General Assembly; representatives of the U.S. Army Corps of Engineers; and members of the environmental community.
The success of the Block Island project was enabled by the strong support of state and local leaders, whom developed early policies for the planning and proper siting of the wind farm, as part of the state’s overall renewables goals and marine spatial planning efforts. Rhode Island’s top officials have all supported offshore wind and the development of the Block Island Wind Farm. Rhode Island’s Congressional delegation also supported federal tax and permitting policies important for this project and industry. Deepwater Wind worked closely with federal and state agencies and local environmental groups in developing a groundbreaking set of construction rules to minimize any impacts on marine mammals.
