I’ve been advocating a 1000% tax on all CA power being generated in or routed through AZ. Screw San Francisco, LA, Berkley, and CA in general!
AZ power goes (nearly all or all, depending on how one works the balances, and enforced by poor transmission capacity between north and south) to Southern Cal.
Northern Cal imports their shortfall from Canada/Washington State, which is nearly all Hydro.
