Sonnenwärmekraftwerk Ivanpah

The Ivanpah Solar Electric Generating System is a concentrated solar thermal plant in the Mojave Desert. Located at the base of Clark Mountain in California, just over the state line between Primm, Nevada and Nipton, California, the plant has a gross capacity of 392 megawatts (MW). It deploys 173,500 heliostats, each with two mirrors, focusing solar energy on boilers located on three centralized solar power towers. Unit 1 of the project was connected to the grid in September 2013 in an initial sync testing. The facility formally opened on February 13, 2014, and it is currently the world's largest solar thermal power station.The project was developed by BrightSource Energy and Bechtel. It costs $2.2 billion; the largest investor in the project is NRG Energy, a power generating company based in Princeton, New Jersey, that has contributed $300 million. Google has contributed $168 million.; the U.S. government provided a $1.6 billion loan guarantee, and the plant is built on public land. In 2010, the project was scaled back from the original 440 MW design, to avoid building on the habitat of the desert tortoise.
