World’s Largest Solar Thermal Power Plant Delivers Power for the First Time

Brightsource Energy announced that its huge, 2.2 billion DOE-funded solar thermal power plant at Ivanpah, California, delivered power to the grid for the first time. It was part of a test to demonstrate the system, which uses mirrors to focus sunlight on towers to generate steam. The steam is then used to spin turbines and generate electricity. The plant isn’t quite finished yet, but is expected to be done by the end of the year.
