Abstract

A power consumption management system. The system includes a power appliance at a consumer site and a power appliance control point at a LSE site. The power appliance is capable of measuring and controlling power consumption on a plurality of circuits located at the consumer site, as well as controlling end consumer devices. The power appliance control point is capable of receiving power consumption data for each of the plurality of consumer circuits, and is capable of commanding the power appliance to control power consumption on individual circuits. The power appliance is further capable of directing power supplied from individual LSE'"'"'s to individual circuits at the consumer site, and capable of varying such usage according to more complex schemes, for example, by time of day or environmental conditions.
