I have heard that internet connected power supplies can be turned on and off remotely to accomplish this. They are already in use in some places, to remotely reduce loads such as large air conditioners during peak hours. Georgia Power installed a smart meter at our house that charges different amounts at different times of day. It transmits data by radio.
