METHOD AND APPARATUS FOR ACTIVELY MANAGING CONSUMPTION OF ELECTRIC POWER SUPPLIED BY ONE OR MORE ELECTRIC UTILITIES

A system, which includes a system controller and client devices, manages consumption of power supplied by at least one electric utility to multiple power consuming devices. Electric power flow to the consuming devices is controlled by controllable devices, which are controlled by the client devices. The controller includes an event manager, a database, and a client device manager. The event manager generates event instructions, including instructions requiring a reduction of consumed electric power. The database stores, on a per client device basis and/or a per electric utility basis, information relating to power consumed by the consuming devices. The client device manager selects, based on the database information and responsive to a power reduction event instruction, at least one client device to which to communicate a message indicating a power reduction amount and/or identification of at least one controllable device to be instructed to disable power flow to associated consuming devices.
