Abstract

A system and method for energy management for multi customer multi time zone distributed facilities are disclosed. In one embodiment, data associated with the energy management of the multi customer distributed facilities located in different time zones is obtained based on associated energy models by a data acquisition/integration layer. Further, the obtained data for energy management of the multi customer distributed facilities is transformed by a data management layer. Furthermore, control commands are generated using the transformed data and associated one or more pre-defined thresholds and set-points by an energy transaction layer. Also, energy of the multi customer distributed facilities is substantially simultaneously managed using the generated control commands by the energy transaction layer.
