Patent ID: 8521336

Claim:
A power reduction aggregation system for controlling and measuring power usage at a plurality of user locations comprising: a plurality of power reduction controllers wherein each power reduction controller is disposed at an associated user location of the plurality of user locations and is configured to selectively control switches to selectively decouple power from or couple power to each load of a plurality of loads associated with the user location, to selectively control the switches to selectively couple each load of the plurality of loads to a first power input or to a second power input; to selectively control the switches to selectively decouple each load of the plurality of loads from the first power input and from the second power input wherein the first power input is from a power utility remote from the user location and the second power input is from a backup power supply local to the user location; and to use switch state information to determine energy reduction indicia associated with at least one load of the plurality of loads; and a power reduction module communicatively coupled to each of the plurality of power reduction controllers and configured to determine an aggregate energy reduction estimate by combining the energy reduction indicia determined by each of the plurality of power reduction controllers.
