Abstract

An energy management system of an embodiment includes first and second registration processors, first and second receivers, an aggregation processor, first and second transmitters, and a proration processor. The first registration processor registers a first energy management system as a host system. The second registration processor registers a second energy management system as a slave system. The first receiver receives an amount of an energy supply and demand and an adjustable amount of an energy supply and demand. The aggregation processor aggregates the received amount of an energy supply and demand and the received adjustable amount of an energy supply and demand. The first transmitter transmits aggregated results. The second receiver receives an adjustment amount of an energy supply and demand. The proration processor prorates the received adjustment amount of an energy supply and demand. The second transmitter transmits individual adjustment amounts of a power supply and demand.
