ENERGY CONTROL SYSTEM, SERVER, ENERGY CONTROL METHOD AND STORAGE MEDIUM

According to an embodiment, an energy management system includes a client and a server capable of communicating with the client. The server includes an acquisition unit, an estimation unit, a calculation unit and a control unit. The acquisition unit acquires data concerning electrical equipment in a building including a storage battery from the client. The estimation unit estimates an energy demand and an energy generation amount in the building based on the data. The calculation unit calculates, based on the energy demand and the energy generation amount, an operation schedule of the electrical equipment to optimize an energy balance in the building under a constraint that minimizes dump power to be discarded after the storage battery is fully charged. The control unit creates control information to control the electrical equipment based on the calculated operation schedule.
