San Francisco, September 17, 2010. Solar Millennium, a power plant construction company based in Erlangen, Germany, is heading a joint project with U.S. oil giant Chevron to develop four large solar power plants. Construction of two plants is set to begin by the end of 2010. The solar thermal plants, located in Blythe, California, will have a combined capacity of some 1,000 megawatts. This would be the first time a solar facility reaches output levels comparable to nuclear power plants. The plants are scheduled to go online in 2013 or 2014.
