In order to reduce demand power on utility grid through electrical energy storage and suppress reduction in remaining capacity of electrical energy storage, power supply control apparatus (10) includes judging module (12) and estimator (13). Judging module (12) judges whether to allow electrical energy storage (20) to feed power into electrical load (41) within target period while electrical energy storage (20) in building (40) is requested to feed power into electrical load (41). Estimator (13) performs estimation of present state in which user of electrical load (41) is present in building (40) or absent state in which user is absent from building (40). Judging module (12) judges to allow electrical energy storage (20) to feed power when estimation by estimator (13) is present state, within target period and judges to prohibit electrical energy storage (20) from feeding power when estimation by estimator (13) is absent state, within target period.
