Nevada Solar One
This page provides information on Nevada Solar One, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration.
Acciona Energy's Nevada Solar One is the third largest CSP plant in the world and the first plant built in the United States since 1999. Located in Boulder City, Nevada, about 40 miles southeast of Las Vegas, this parabolic trough system has been operating since June 2007. The US$260 million plant has a nominal production capacity of 64 megawatts with a maximum capacity of 70 megawatts. All of the plant’s electricity, which can power more than 14,000 households annually, is being sold to Nevada Energy under a long-term power purchase agreement.
