PROBLEM TO BE SOLVED: To keep a voltage of a low-voltage power distribution line within a reference value by using the power generation of a home distribution power supply such as a photovoltaic panel even in a time zone at which surplus power form an ordinary house is generated.SOLUTION: The power demand management device includes: a surplus power prediction part which acquires surplus power information related to surplus power in the past which was generated from a plurality of facilities and predicts the surplus power on the basis of the acquired surplus power information; and a transmission part which transmits power accumulation request information including a power accumulation request amount and a power accumulation request time to the facilities on the basis of the predicted surplus power. |
