A demand response system incorporating an enterprise demand manager (EDM), and a universal demand response gateway (UDG). The EDM may provide a single unified web interface. It may provide a cloud application that allows an operator of an enterprise to create and send load/energy reduction requests to buildings of one or more groups of buildings in the enterprise. The cloud application may provide controls to the buildings based on market conditions, dispatch demand response (DR) events to the buildings, and provide feedback to confirm that requested reductions are occurring in the buildings. The DR events may include the buildings in an energy market, a load/energy reduction intensity level, and a target load/energy reduction amount for each building. The UDG may perform as a gateway between various DR automation servers (DRAS's) and multiple supervisor controllers at the buildings.
