Ah, this is why I come here. I had no idea that was the case. I feel like there was a story going around recently about how hard it is to restart some power generator if it gets knocked offline. Maybe it was about Hoover Dam now that I think about it (i.e., how bad it would be if the Colorado gets too low).
