A power management method and system. The method includes retrieving and storing by a computer processor, identification data identifying power consumption devices. Each power consumption device receives an input voltage signal and consumes power. The computer processor monitors a power consumption level for each power consumption device. The computer processor disables each power consumption device from receiving and consuming power. The computer processor generates an association list associating each power consumption level with the identification data. The computer processor generates and stores a prioritization list indicating an order of priority for disabling the power consumption devices.
