Abstract: Provided herein are systems, methods and computer programs for generating a facility reconfiguration plan (FRP) useful to reconfigure a facility's energy system to achieve a financial objective. The facility's energy system and associated economics are characterized prior to any modifications. Additionally, there's a determination of which of a plurality of potential modifications, if any, is to be added to the FRP by determining which of the potential modifications provides a financial benefit useful to achieve the financial objective, and has a greatest financial attractiveness. The FRP is generated by repeating the aforementioned determination multiple times, wherein during iterations following an initial iteration, potential modification(s) already identified as providing a greatest financial attractiveness during previous iteration(s) is/are removed from consideration.
