A system according to the present invention including a main utility distribution panel which through corresponding circuit breakers, directly powers facility power line circuits which remain powered continuously, and an ‘off-peak’ utility distribution panel being powered by the main utility distribution panel through a contactor (relay, switch, etc.) controlled by a 24 hour timer, and the ‘off-peak’ utility distribution panel in turn powers facility power line circuits which may be de-energized to provide zero power draw from the main utility distribution panel during a selected time period as provided by the timer, which generally corresponds to periods when the facility is unoccupied and/or the equipment and appliances are turned off.
