The generator looks like it’s in a hydro plant, so that was my assumption. I’ve heard of one in Wyoming or Colorado with a rock wall in the control room, but I’ve never seen anything like that before.

What power plant is this? Is that a rock wall in the back? Was this built into the side of a mountain?

The issue is those coal, nuclear, hydro plants are what produce power when the sun isn’t out. If you consistently shut them down for solar, they will go out of business and there will be no way to provide electricity when solar doesn’t.
