Abstract

According to embodiments, a regional energy integrated management device for managing energy in a region containing multiple buildings includes an information acquisition unit, an information generator, and an instruction transmitter. The information acquisition unit acquires energy management information containing energy shortage and surplus information of a building from the multiple buildings. The information generator generates regional energy management information for mutually adjusting energy supply between different buildings in the management target region based on the energy management information on the multiple buildings thus acquired. The instruction transmitter transmits the generated regional energy management information to the corresponding buildings.
