Installation Work Starts on First U.S. Offshore Wind Farm

Rhode Island's Deepwater Wind began installing the foundations for North America's first offshore wind farm on Monday, a milestone the company says could pave the way for an industry long established in Europe but still struggling with opposition in the United States.

The 30-megawatt wind farm, which will include five turbines located three miles (4.8 km) off the coast of the bucolic summer tourist destination of Block Island, will take more than a year to build and is scheduled to produce electricity for the tiny island community and the mainland by the end of next year.

"Our belief is once Block Island is up and running, it will bring offshore wind from theory to reality in the United States and open up opportunities to build larger projects," said Jeffrey Grybowski, Deepwater Wind's CEO.

Representatives from the U.S. Department of the Interior, the Bureau of Ocean Energy Management and environmental organizations toured the offshore construction site in overcast conditions on Monday morning, as vessels hauled the giant steel foundations into place.

Offshore wind projects have been delivering power in Europe since the 1990s, with nearly 2,500 turbines connected to the grid, but they have struggled to gain a foothold in the United States due to worries about cost, the aesthetics of towering wind turbines within view of the coasts and the impact on birds and whales.

A rival project, Cape Wind's proposed 130-turbine wind farm off Nantucket Sound, for example, was for years expected to be America's first such project but stalled in part due to a lack of local support. Other offshore wind projects are in limbo off Delaware, New Jersey and New York.

Deepwater's project fits a different mold, according to Grybowski and the project's backers, French bank Societe Generale and Ohio-based Key Bank: It was relatively small and therefore easier to finance and is set in a location that has substantial built-in government and local support.

"Rhode Island was very forward-thinking and had designated a specific development area," said Alexander Krolick, Societe Generale's energy project finance director for the Americas. SocGen and Key Bank have provided about $300 million for the project, according to Deepwater, which is based in Providence.

Block Island was chosen as a wind power site by the state in 2007 in part as a solution to the island's own energy woes: Its 1,000 residents have for years relied on costly diesel-fired generators for electricity. Once the wind farm starts up, prices will drop 40 percent, according to a study by the Block Island Utility Task Group.

"We have some of the country's highest electricity prices," said David Kane, who retired to the island a few years ago. "This is going to help us a lot."

Britta Schulte, a German tourist who was visiting Block Island's Southeast Light House on a bluff overlooking the work site on Monday, said she did not expect the wind turbines to create an eyesore for vacationers.

"It will look fine. It will still be beautiful," she said. "Besides, I think it is about time America starts catching up with Europe on wind anyway."


About 90 percent of the wind farm's power will be shipped to Rhode Island's mainland via an undersea cable where utility National Grid will buy it for 26 cents/kwh and mix it into the rest of the state's supply, which generally ranges between 6 and 10 cents/kwh. Although it will account for only one percent of the state's power supply, the higher cost represents the industry's biggest challenge.

"Everybody shares the view that we need to make progress to decrease the cost," said Jerome Deflesselles, Societe Generale's head of renewable origination for Europe. He said more efficient turbines and cheaper construction methods could help offshore wind compete with traditional power within about five years.

The foundations for Deepwater's wind turbines were produced in Louisiana and will be fixed with pilings penetrating more than 150 feet (46 m) into the sea floor over the next few months. Deepwater said it had agreed to do the pile driving only when migrating whales are not in the area.

The towers and five Haliade 150 6 MW turbines, produced by Alstom in France, will be installed next summer and fall. Gulf Island Fabrication built the wind farm’s five steel jacket foundations.

Deepwater said if the project is successful, it could pave the way for expansion. It holds a 30-year lease on a parcel in federal waters about 15 miles (24 km) southwest of Martha’s Vineyard with room for as many as 250 turbines.

“We are on the cusp of bringing offshore wind from theory to reality in the U.S. We’re incredibly proud of our position at the forefront of the U.S. offshore wind industry,” Grybowski said. “We’ve brought together some of the best American and European expertise to build an outstanding project and finance team. We’re poised to launch a new American clean-tech industry, and it all starts here with our work on the Block Island Wind Farm.”


U.S. offshore industry body, NOIA, issued a congratulatory statement by President Randall Luthi: 

“NOIA congratulates Deepwater Wind as on-site construction begins on its Block Island Wind Farm offshore Rhode Island. It is gratifying that Deepwater Wind chose NOIA member company Gulf Island Fabrication for the off-site construction of the foundations for this project, which is on course to be America’s first offshore wind farm. It is also fitting that a company best known for fabricating offshore oil and gas structures played a role in constructing this historic project.  

“NOIA has long supported an all-of-the-above offshore energy strategy, and we look forward to seeing more partnerships between offshore renewable companies and offshore oil and gas companies made possible by the success of the Department of the Interior’s offshore wind leasing program.  

“The U.S. derives about 17 percent of its domestic oil production, and about five percent of its domestic natural gas production from offshore areas, even though current federal policies prohibit oil and gas development off the Atlantic Coast. Offshore wind combined with offshore oil and gas in the Atlantic and additional areas of the outer continental shelf will strengthen our nation’s energy security, produce thousands of new jobs and benefit American consumers.”
