System and method for estimating demand response in electric power systems

A system and method for use in a network of utility customers to estimate demand response for various utility DR programs. The system first aggregates the premises (104) into clusters based upon customer information for each of the premises (602,604,804). A response estimation function is developed for each of the clusters (606,706,808,906). The demand response event request is then processed according to the clusters and the response estimation functions.
