World’s biggest solar thermal power plant fired up in California
The 3,500-acre Ivanpah Solar Electric Generating System is a startling sight in the Mojave Desert. Three sprawling units each contain a circular array of mirrors reflecting rays from the sun toward a 459-foot central tower. Water in the tower is heated by the rays to produce steam, which spins turbines and — voila — electricity is produced.
It all seems a bit magical, but as of Tuesday, the world’s largest solar thermal power plant began feeding energy into a power grid for the first time.
How much energy? Once fully operational, the project is expected to produce 377 megawatts of power that will be sold to two Californian utilities, helping the state’s electricity sector meet ambitious, state-mandated renewable energy goals. During some days it could provide enough power for more than 200,000 homes.
Partners in the project include NRG Energy, BrightSource Energy, Google, Bechtel and, of course, you and me. The federal government leased public land to the effort and backed it up with one of those loan guarantees that you heard so much about in 2011 and 2012.
