Inside a Demand-Response System

Spara handles demand control by carefully choosing from a series of preselected loads. It then sheds the exact desired amount of power — or as much as possible given facility-specific rules. The algorithm it uses to make decisions about the frequency and duration of curtailment events contains two key elements: a predictive model that can be tuned to filter out intermittent demand spikes, and a calculation proven over time to select the best-fit loads needed to reach a prescribed curtailment level (so there are no unnecessary reductions in power).
