Abstract: A load management system includes a load management control center, at least one power management termination system, a plurality of power line nodes, and a plurality of load management devices. This system is operable so that the load management control center may independently, or as a group, control each of the load management devices. According to one aspect of the present invention, the load management control center accesses the load management devices across a communication network that includes a power line network. The load management devices may be addressed individually. Alternately, the load management devices may be addressed as a group or set of groups by the load management control center during load shedding operations. Load management devices may include meters that are communicatively coupled to the load management control center.
