Disclosed is a system and method for improving grid efficiency, reliability, security and capacity, utilizing energy storage over a plurality of on-site energy storing appliances, and also utilizing on-site demand reduction devices lacking storage, all controlled via configuration settings with a local means to act independently, yet in statistical coordination, to provide a desired effect. The appliance and controller are located on the downstream side of the end-users power meter, and facilitates the utilization of the stored energy and manages the optimal timing for producing and delivering the stored energy to the end-user. This model demonstrates a utility driven, disaggregated, distributed energy system, where the distributed energy resource is designed to behave as an offset to the predictable daily electrical demand profile.
