If AZ cuts off the power outright, the news will be full of pictures of old folks and babies dead from the heat (regardless of the real cause, the message will be it’s AZ’s fault). I think just raising rates (to compensate for the economic damage from boycotts against AZ) is smarter, both fiscally and politically.
I don't see Arizona flipping that big switch and the CA lights go off. Never going to happen, Cutting back on how much they transmit will have the desired effect. .
Remember 1993 Soylent Green where Edward G Robinson (his last movie) had to pedal a generator bicycle to keep the one light on? Couldnt California do something like that? It's green. Also it could be part of a Obamacare type health program.
