Abstract

A method and apparatus are provided for filling a gap of missing data using source specified data. The method includes analyzing a first set of data representative of utility consumption for a plurality of days to determine clusters of days of the week having similar utility consumption. The method further includes generating an individual profile of utility consumption for each cluster, and copying data from at least one individual profile into the gap to form a second set of data without any gaps. A system for filling a gap of missing data using source specified data includes a microprocessor programmed to copy data from at least one individual profile into the gap, and to adjust the copied data up or down to account for local trend information adjacent to the gap.
