PROBLEM TO BE SOLVED: To provide an energy management system capable of preventing excess power from being wastefully consumed.SOLUTION: According to an embodiment, an energy management system manages the energy of a customer's house provided with a hot water supply apparatus using renewable energy as its heat source. This energy management system comprises an acquisition unit, a prediction unit, a creation unit, and a control unit. The acquisition unit acquires, from the customer's house, data pertaining to energy-related apparatuses including a hot water supply apparatus, a power generation device, a power storage device, and an energy consuming device. The prediction unit predicts, on the basis of the data, an energy demand and supply amount in the customer's house. The creation unit creates, on the basis of the energy demand and supply amount, an operation schedule for minimizing energy cost in the customer's house on condition that excess power discarded when the power storage device is fully charged be minimized. The control unit controls the energy-related apparatuses on the basis of the operation schedule. |
