The Ivanpah Solar Energy Plant

July 11th, 2014 by Roy W. Spencer, Ph. D.

After attending Heartland’s 9th International Conference on Climate Change (ICCC9) in Las Vegas, we drove into the Ivanpah solar generating facility near the Mojave Desert in southern California.

Here’s a Google Earth view, with the location I drove to for a couple of photos:

With over 170,000 mirror assemblies reflecting sunlight onto 3 steam generating units, the plant is advertised to generate a peak power level of 390 MW.

There were storms in the area, and some of the surrounding land was actually flooded. Only one of the 3 solar arrays was illuminated through a break in the clouds when I was there, seen in this zoom photo:

This wider-angle photo now shows better solar illumination of the far tower, which is accompanied by concentrated sunlight scattered by aerosols in the air around the tower:

The facility cost $2.2 billion, and Google was even a partial supporter early in the project. It would be interesting to hear how much energy the facility actually generated after a year of operation.
