An intelligent demand controller protects the local customer premises supply transformer from overload and senses conditions on the transformer. The intelligent demand control system utilizes a communications network with a plurality of load control units having a unique address and residing at a plurality of customer premises. A demand controller monitors the voltages and frequency of electricity provided to the customer premises as well as the instantaneous current required by the operating loads of the customer premises. Each of the plurality of demand controllers may be associated with one or more of a plurality of load control units and configured to receive data related to the state of the power supplied to the plurality of controlled loads and generate a transmit message using a predefined communication protocol. When certain programmable conditions are met, a load control unit is signaled to remove power from one or more of its monitored loads.
