Abstract
An energy management system which automatically limits the total instantaneous consumption of electrical energy in a residence having a plurality of energy consuming loads having different current demands, while maintaining the consumption of electrical energy as high as possible without exceeding a predetermined peak total current demand. Sensor means measure the total current to all of the loads which are then in operation and generates a signal indicating the total current. Current interrupters, controlled by the logic of a microprocessor automatically interrupt the current, if any, to each of the loads in a predetermined sequence, when the total current to the loads then in operation exceeds the predetermined peak total demand. Enough of the loads are shed until the total current is less than the predetermined peak total. The microprocessor then selects, from among those loads which have been interrupted, those which can be restored without causing the total current to exceed the preselected peak demand and generates signals which cause the interrupters to restore current to the selected loads.
