Abstract: A power consumption prediction apparatus, method, and non-transitory computer readable storage medium thereof are provided. The power consumption prediction apparatus receives a plurality of power consumption data of an appliance, wherein the power consumption data have a temporal sequence. Each power consumption datum includes a recorded status and a recorded time length, wherein each recorded status is one of a plurality operation statuses of the appliance. The power consumption prediction apparatus calculates an average operation time length of each operation status according to the recorded statuses and the recorded time lengths and calculates at least one transferring probability of each operation status according to the temporal sequence and the power consumption data. Each transferring probability is the probability of entering into a target status from a source status, wherein the source status is one of the operation statuses and the target status is one of the operation statuses.
