An electronic device and a method for management of power supply in enclosed space is provided. The electronic device determines first information indicating a disruption in a main power supply of a first enclosed space. The electronic device determines second information which indicates a power consumption of one or more electrical appliances in the first enclosed space based on the determined first information. The electronic device further determines third information associated with one or more secondary power supplies in the first enclosed space. The electronic device further applies a trained ML model on the determined first information, the second information, and the third information and determines scheduling information based on the application of the ML model. The electronic device further controls the one or more secondary power supplies to power the one or more electrical appliances, based on the determined scheduling information.
