Energy management system

[Problem] The objective of the present invention is to provide an energy management system that increases the local power production and consumption rate and allows power to be used economically and efficiently. [Solutions]An energy management system(1) comprising a control unit(26). The control unit(26) calculates the predicted value of the total amount of power consumed in the first area(10), on the basis of the actual measured value of the total amount of power consumed in the first area(10), the weather forecast data. The control unit(26) determines if there is surplus power in the first area(10), on the basis of information including the data about the predicted amount of generated power and the predicted value of the total amount of consumed power.
