Patent ID: 7885917

Claim:
A utility monitoring method comprising: acquiring electricity consumption data representing electrical consumption of a plurality of loads; extracting waveforms associated with at least one of the plurality of loads from the electrical consumption data; applying a disaggregation algorithm to the electricity consumption data to identify at least a first load of the plurality of loads and produce disaggregated data representing the electrical consumption of the first load, the disaggregation algorithm comprising determining power state transitions of at least one of the plurality of loads based on its waveform, comprising measuring an amount of electricity consumed by the first load, measuring an amount of another utility consumed by a device associated with the first load, and based on the measured electricity amount and measured another utility amount, determining the identity of the first load; transmitting the disaggregated data to a user interface device or user computer; and presenting a user with electricity consumption data for at least the first load.
