DOE Awards Nearly $1.4 Billion in Loan Guarantees to BrightSource Energy

February 22, 2010

DOE announced on February 22 its conditional commitments for more than $1.37 billion in loan guarantees to BrightSource Energy, Inc. in support of the construction and start-up of three utility-scale concentrated solar power plants (CSP) in the Mojave Desert of southeastern California. The loan guarantee is funded under the American Recovery and Reinvestment Act and is predicated on BrightSource meeting financial and environmental requirements before closing on the loan. The Bureau of Land Management is leading a federal review of the project with support from DOE. Pending local, state, and federal regulatory approval, the new plants will generate approximately 400 megawatts (MW) of electricity using the company's proprietary technology. This output would nearly double the existing generation capacity of CSP facilities in the United States.

The three-plant Ivanpah Solar Complex will be located on federally owned land near the Nevada border and will be the world's largest operational concentrated solar power complex. BrightSource will employ solar power tower technology, which uses thousands of flat mirrors, or "heliostats," to concentrate the sun's heat onto a receiver mounted at the top of a tower. Water pumped to the receiver is boiled into steam, which drives a turbine to produce electricity. Solar power towers allow the capture of a greater percentage of solar energy than other solar thermal technologies. The first plant is expected to begin construction in the second half of 2010 and come on line in 2012. Commercial operation for the second plant is slated for mid-2013, with the third plant following later that year. Once operational, the project will supply power to approximately 140,000 California homes. The BrightSource loan guarantee is the sixth conditional commitment for a loan guarantee for clean and renewable energy projects entered into by DOE's Loan Programs Office.
