Mojave Solar Project, California

The Mojave Solar Project is a solar power plant started in 2011, and finished in 2014. It is a solar thermal plant, using mirrored parabolic troughs, not photovoltaic panels. At 280 megawatts, it is among the largest plant of this type in the nation. The Spanish company Abengoa built the $1.6 billion facility, which is located in Lockhart, California, next to the Harper Lake Solar Electric Generating Station, which for more than 15 years was the largest solar power plant in the nation, producing 160 megawatts as early as 1990, and which is also a parabolic trough type. With the combined capacity of 440 megawatts for the two plants, this is among the largest solar electric generating sites in the USA.
