Abstract: Methods, systems, and techniques for determining the confidence that predicted demand charge savings resulting from deploying an energy management system at a site will match actual cost savings. A processor obtains predicted demand charge savings resulting from deploying the energy management system at the site, and also obtains demand-related data describing at least two of load predictability, load shape, and battery capacity of the energy management system. The processor determines a confidence score representing the confidence that the predicted demand charge savings will result in view of the demand-related data, and displays the confidence score on a display for subsequent use by a user.
