ABSTRACT:
A method and system for curtailing energy consumption of an appliance, such as an air conditioning compressor or heat pump, is provided. A control unit stores information relating to the load, which may include a connected load value, such as a power consumption value or efficiency rating. The control unit then monitors the appliance to determine when the appliance is calling for energy. Upon receiving an energy reduction value from a remote source, the control unit then calculates a permitted run time from the energy reduction value and the connected load value. The control unit, through a switch, then permits the appliance to be operable only for the permitted run time so as to reduce power consumption by a predetermined amount.
