ABSTRACT:
An energy management system for limiting continuously instantaneous permissible power level of a plurality of controllable loads including a transducer device for generating an output signal when the measured instantaneous power level exceeds a pre-set instantaneous permissible power level. A programmable matrix device is provided to select a plurality of controllable loads and periods of time in a day for which each of the selected loads are connected to a power source. The selected controllable loads are disconnected from the power source in response to the output signal in a predetermined order. The order in which the selected loads are to be disconnected is sequentially switched over a certain time interval.
