Solar Magic in the Mojave: The Ivanpah Solar Electric Generating System

November 1, 2015

Every day the Ivanpah Solar Electric Generating System generates enough electricity to power a small American city. That’s quite a feat considering its location: The remote, sun-drenched Mojave Desert in Southern California.

By tracking the sun, the heliostats capture enough energy to generate some 377 megawatts of carbon-free electricity. This well-calibrated system involves mirrors that capture solar energy, water that’s heated into steam, and turbines tapping the steam to generate electricity.

Building this first-of-a-kind plant in the middle of the desert was a challenge. But thanks to a well thought out construction plan, Bechtel was able to install 500 heliostats per day—increasing that number to 800 during peak construction. And it did all of this over a three-year period, delivering the plant to owner NRG Energy without recording a single lost-time incident.
