Bechtel Corp. moved into the renewable-energy sector in a big way on Sept. 14, announcing it would develop and own an offshore wind farm on Lake Erie with partners Cavallo Energy LLC and Great Lakes Wind Energy. The five-turbine, $100-million project, seven miles from Cleveland, could become the first offshore wind farm in the United States. “There is no question that renewables is a growth area … we are moving into,” says Sprague Cook, vice president and manager of renewable power for Bechtel. The San Francisco-based multinational engineering-construction firm is looking into both onshore and offshore wind development, he says.
On Sept. 15, the U.S. Nuclear Regulatory Commission said it is revising its rules to allow storage of spent nuclear fuel for at least 60 years after the licensed life of any reactor, doubling the time previously allowed. The fuel can be stored on-site or at independent spent-fuel storage installations without significant environmental impacts, says NRC. The change gives federal officials more time to find a permanent storage solution for the nation’s spent nuclear fuel. Earlier this year, the Obama Administration stopped work on the Yucca Mountain nuclear-waste depository in Nevada. An Obama-named commission is to recommend new options by
One of the largest distributed commercial solar retrofit projects in California required creative planning, design and logistics. In April, Sacramento-based HMH Builders completed the first of 15 1 MW photovoltaic additions to health provider Kaiser Permanente buildings up and down the state as part of an Engineering, Procurement and Construction agreement with San Francisco-based solar developer Recurrent Energy. Because the first application was on the 400,000-sq-ft rooftop of a regional distribution center in windy Livermore where gusts can reach 115 mph, HMH switched from a planned ballasted design that used weights to anchor photovoltaic trays to a connected system. Steel
West Coast solar power could get a major boost if the California Energy Commission approves as many as six of 13 proposed utility-scale solar projects in Southern California’s Mojave Desert by year-end.

Other systems under consideration use thin-film compounds and waterless thermal troughs. At a series of meetings in October and November, the CEC will consider authorizing construction for some of the largest solar installations since 354 MW went online in the 1990s. An additional 3,500 MW of capacity—an estimated $18 billion
Pepco, the electric utility that serves Washington, D.C., and its Maryland suburbs, will spend $256.5 million over the next five years to accelerate planned improvements to its distribution system after it struggled to recover from a severe thunderstorm in late July. More than 322,000 Pepco customers lost power after the storm; the company took five days to restore the power. The utility added $115 million to a planned system reliability upgrade after executives were grilled by the Maryland Public Service Commission about their response to the July storm and back-to-back snowstorms in February. Earlier this month, Pepco asked state regulators
Hyperion Power Generation, Santa Fe, N.M., has agreed to build a prototype nuclear mini reactor at the U.S. Energy Dept.’s Savannah River site in Aiken, S.C., officials said on Sept. 9. It signed a memorandum of understanding with the Savannah River National Laboratory to build what officials say would be the first of several small demonstration reactors at the site. Hyperion is developing a 25-MW fast-neutron reactor that uses uranium nitride fuel and lead bismuth eutectic coolant. The operational prototype should be built by 2017 or 2018, says a DOE site spokesman. The demo reactor, with a current cost estimate
Deere & Co.’s recent agreement with Exelon Corp. to offload its wind-farm division for $900 million comes at a time when construction activity in wind power is anything but breezy. Photo: Tudor Van Hampton For ENR A lack of federal legislation for renewable energy is holding back the market for wind power and green jobs, supporters say. “The overall economy has affected this market,” says Tom Wacker, senior vice president of M.A. Mortenson Co., Minneapolis. “But the business has very much experienced a boom-and-bust cycle, and that’s because of the lack of consistent federal legislation.” During 2010’s first half, Mortenson
Cape Wind, the estimated $1-billion offshore wind farm planned for Nantucket Sound off the Massachusetts coast, cleared a major hurdle on Aug. 30. The state supreme court upheld a state board’s approval for an underground and undersea transmission line between the project’s 130 proposed turbines and the regional power grid. Cape Wind, set to generate 420 MW of power, had federal approval to build, but its 18.4-mile power line required state siting approval. The 4-2 decision effectively upheld the state board’s ability to overrule local authorities, which had denied Cape Wind’s permit request.
In a first-of-its-kind deal, waste management firm EnergySolutions Inc. has taken control of the shut-down Zion nuclear powerplant near Chicago from owner Exelon Corp.; the firm will decommission and dismantle the facility, built in 1973, and return it to a greenfield state under budget and ahead of schedule. The U.S. Nuclear Regulatory Commission has granted EnergySolutions, Salt Lake City, control of the Lake County, Ill., plant’s license. The firm is set to clean up the 257-acre Lake Michigan site in seven to 10 years, including paperwork and environmental remediation, and return license and site control to Chicago-based Exelon.The industry standard
Through most of the past decade, rising demand for electricity in the U.S. led utilities and independent power companies to plan, design and build scores of new powerplants.
