Solar thermal can't really compete economically with photovoltaics.

I think they are shutting it down. It had the nasty habit of frying birds that ventured too close to it. And that particular valley actually is far more cloudy then what you would expect for the desert near Las Vegas.

Thanks for pointing that out. I'll update the post.

scheduled to shut down two of its three units in 2026
