要約
(EN)

A power information collecting apparatus efficiently collects power information including a power consumption level of each of a plurality of devices. A power information collecting apparatus (11) which collects power information including a power consumption level from each of a plurality of devices (13), and includes: a communication unit (113) collecting power information of each device (13); a data holding unit (111) holding the power information collected by the communication unit (113); a change rate calculating unit (112) calculating a power change rate indicating a degree of increase and decrease of the power consumption level for each device (13), using the power information held by the data holding unit (111); and a controller (114) controlling the communication unit (113) such that the frequency of power information collection is higher for a device (13) having a higher power change rate calculated by the change rate calculating unit (112).
