Located in Riverside County, the multi-billion dollar project will be the first parabolic trough solar facility approved on US public land.

Solar Trust of America, a joint venture between Germany-based Solar Millennium and industrial services provider Ferrostaal, is developing the Blythe power project, which will cover 7,025 acres in the Mojave desert.

A total of four solar-thermal power plants will be built at the Blythe location, and the construction of the project is expected to begin by the end of this year.

The US Department of Interior secretary Ken Salazar said that the Blythe power project is a major milestone in renewable energy economy of the US and shows that the nation intends to compete and lead in the technologies of the future.
