The Hamster is on Go Slow for better food
Happened to me in central Nevada. Seems power company lost half the state, took a few hours to get back up.
You don’t turn on a load that large all at once - you’ll ruin your generators and transmission lines. You do it a small sector at a time, wait for everything to settle out, then on to the next sector.
Fortunately, the combo dining facility / bar had a 500KW generator attached. It spun up “Right Now” and we had a place to gather. The bar, not the dining end.
Nothing useful got done that night (grin).
