The present disclosure provides systems and methods for shaping the load of a building for more efficient sizing and/or economics of an energy storage and/or microgrid system. Shaping the load of a building can include identifying a plurality of core hours of a time period increasing a load of the building, a plurality of different increase instances, by interfacing with a BAS and an ESS during the plurality of core hours, and decreasing the load of the building, a plurality of different decrease instances, by interfacing with the BAS and the ESS during the plurality of core hours, wherein each increase instance from the plurality of different increase instances of the load profile is followed by a decrease instance from the plurality of decrease instances of the load profile.
