A process for calculating feasibility of an electrical energy consumption management system (CMS) includes receiving a first historical energy consumption profile of an energy consumer for a first time period and a second historical energy consumption profile of the energy consumer for a second time period, wherein the second time period is after the first time period. The process may also include determining a setpoint for a CMS, wherein the CMS has hardware specifications, and wherein the setpoint is based on the first historical energy consumption profile and the hardware specifications. Next, an energy savings that would be produced by the CMS over the second time period is determined and a feasibility rating is assigned to the CMS based on the first energy savings and the first hardware specifications. A customer may thereby determine or optimize the effectiveness of a CMS at his site before it is purchased and installed.
