According to one embodiment, an energy management apparatus includes a power generation estimation unit, a demand estimation unit, a creation unit and a controller. The power generation estimation unit estimates a power generation amount of a power generation apparatus using a renewable energy. The demand estimation unit estimates an energy demand of an electrical device of a customer. The creation unit creates an operation schedule of the electrical device based on the estimated power generation amount and energy demand. The controller controls the electrical device based on the operation schedule. The demand estimation unit includes a storage unit, an extraction unit and a calculation unit. The storage unit accumulates load data representing a result of a load of the electrical device. The extraction unit extracts a plurality of load patterns including a plurality of different load data from the accumulated load data. The calculation unit calculates a weight based on a predetermined standard for each of the extracted load patterns. The creation unit includes a simulator and a schedule creation unit. The simulator simulates, using a predetermined algorithm, an evaluated value of each operation schedule based on the extracted load pattern and the weight of the load pattern. The schedule creation unit creates the operation schedule based on the evaluated value.
