Entirely incorrect. Not only can the state store energy in reservoirs during the day to produce hydro at night, there are battery banks like that one in LA that went into flames. But most importantly, they use an app to throttle solar into the grid to reduce fuel use. I mean, that’s the whole point! If you make enough solar, they can stop running some random power plant somewhere. Some power plant’s cannot easily be turned off or throttled down. That’s a them problem.
