Abstract: A method and device for performing a sampling methodology for measuring power consumption for a population of power-consuming devices. The device includes a processor configured to perform the method. The method includes determining an energy consumption level for each device in a population of power-consuming devices; clustering the population of power-consuming devices into a plurality of clusters such that each of the plurality of clusters has a similar overall energy consumption; determining an estimated total energy consumption for each cluster; determining an estimated total energy consumed by the population of devices based upon the total energy consumption for each cluster, wherein the estimated total energy consumed by the population is within an acceptable uncertainty; and determining a number of samples to measure in each cluster such that the uncertainty associated with the estimated total energy consumed by the population of devices is minimized.
