A method for load control in an electrical distribution system using energy usage profiles based on temporal measurements. A load control unit () installed at a customer site profiles equipment (E-En) directly connected to the load control unit and remotely located equipment (RE-REn) wirelessly connected to the load control unit using measurements of time rather than energy usage. This reduces the cost and complexity of the load control unit. Profiling is done for individual pieces of load controlled equipment rather than for the site as a whole. This improves data resolution. The load control unit controls the load only when the equipment is powered, and adaptively synchronizes load shedding during this time, so to improve local load control performance. Termination of a load control event results in gradual reduction in load shedding so to control the inrush of demand seen by the distribution system. Performance metrics related to the load control are provided to the utility such that complexity of the system is reduced through decreased computations.
