The United States’ first offshore wind farm has opened off the coast of Rhode Island, ushering in a new era in the country for the industry.
GE and Deepwater Wind have partnered to build five massive turbines three miles off Block Island to power about 17,000 homes, a project costing about $300 million (£235m). It announced on Monday that the wind farm has begun producing energy for the grid and started delivering power to the New England grid on December 12.
Deepwater Wind CEO Jeffrey Grybowski calls the opening a momentous occasion that unlocks the code of how to do offshore wind in the US at a crucial time when states are trying to figure out how to replace aging power plants.
“We’re more confident than ever that this is just the start of a new US renewable energy industry that will put thousands of Americans to work and power communities up and down the East Coast for decades to come,” he said in a statement on Monday.
Abigail Ross Hopper, director of the Bureau of Ocean Energy Management, said the wind farm proves that offshore wind can happen safely and efficiently.
“We’ve gone from the theoretical to the actual and you can’t replace that with any model,” she told The Associated Press in a recent interview. “To be able to go and see turbines spinning in U.S. waters is incredible.”
Deepwater Wind installed the wind farm over two years, with the five 560-feet tall turbines, double the height of the Statue of Liberty, installed in August. National Grid is buying the output.
It had planned to open the wind farm in November, but it took more time to get final approvals from regulators. The company said this month that a turbine wasn’t turning because its generator was damaged by a drill bit left inside but that the issue wouldn’t delay the startup. Deepwater Wind was selected as the state’s offshore wind developer in 2008.
Many Block Island residents supported the wind farm as a way to drive down the island’s high energy costs, though some opposed it out of fear that the turbines would dramatically alter ocean views that both residents and visitors enjoy.
The wind farm is expected to supply about 30 megawatts of electricity annually. National Grid said that is more than enough to meet Block Island’s current demand and the excess will be redirected to mainland Rhode Island through a submarine cable.
The offshore wind industry is far more advanced in Europe.
Mr Grybowski said the industry is focusing on markets where states have indicated a strong interest in developing an offshore resource, including New York and Massachusetts. Deepwater Wind is negotiating with a New York utility to build a 15-turbine wind farm off eastern Long Island.
Democratic governor Gina Raimondo has said she wants Rhode Island to be the most collaborative and aggressive state in creating a supply chain for wind energy, to bring electricity costs down and to address climate change.
“We’re motivated by our shared belief that we need to produce and consume cleaner, more sustainable energy and leave our kids a healthier planet, but also by this tremendous economic opportunity,” she said on Monday.
BOEM has awarded 11 commercial offshore wind energy leases for sites in the Atlantic Ocean. Another lease sale is planned for Thursday for the rights to develop a huge offshore windfarm between New York and New Jersey. Groups representing the fishing industry in four states sought to delay the auction. But an agreement between the groups and BOEM will allow it to proceed.
