Abstract

The present disclosure relates to a method and system for determining potential energy savings for a multisite enterprise by an energy evaluation system. The energy evaluation system receives energy consumption data and plurality of variables associated with plurality of sites and identifies a category for the plurality of variables based on a relationship of the plurality of variables with the energy consumption data. The energy evaluation system further determines one or more significant variables based on an impact of the plurality of variables on the energy consumption data and category of the plurality of variables. The energy evaluation system identifies a plurality of clusters for the multisite enterprise based on the one or more significant variables, evaluates the plurality of clusters of variables and optimizes the plurality of clusters of the plurality of variables based on the evaluation. Based on the evaluation and optimization a potential energy savings is determined.
