You won't be switched off. You'll pay 10x for the electricity you use. If you use too much more, you'll pay 100x. And so on.

What no one here has metered usage read monthly or bi-monthly? I don’t get the big stink over it, variable rates are commonly less expensive when averaged annually. I would tend to believe that a real-time rate which the consumer can see would be an advantage. If gasoline prices varied during the day wouldn’t most people fill up at a time when its less expensive?
