'The Ivanpah Solar Electric Generating System officially came online on February 13, becoming the world’s largest source of solar power. With a capacity of 392 megawatts, the solar system will be able to generate enough power for 140,000 homes in California. The $2.2 billion Ivanpah project is located in the Mojave Desert and is a joint venture by NRG Energy, Google, and Brightsource Energy. Secretary of Energy Ernest Moniz toured the plant today with NRG CEO David Crane.
Ivanpah uses concentrated solar power (CSP), which uses hundreds of thousands of mirrors to reflect the sun towards a tower. This heats a boiler in the tower, which creates steam to drive turbines and make electricity.'
