Same here. They lost power in town a couple days ago. Electric company sent out notices for voluntary usage cuts.
The second or third day of the heat wave, here, we must have had voltage cuts. My efficient, through-the-wall a/c that keeps 2 rooms w/computers/TV/media livable kept blowing its circuit breaker. The situation lasted about an hour and was early in the day, about right for everyone starting up their appliances and a/c.
I am not looking forward to my July power bill.
