Abstract

An approach to provide power from power supply devices to power consuming devices based on using priority levels for each of the power consuming and supply devices. The approach includes the steps of receiving information of a power consuming device from an energy management, including criticality information obtained from a universal appliance service system. The approach further includes receiving power supply information of one or more power supply devices associated with an electric grid, and receiving a power request from the power consuming device. The approach further includes determining that the power consuming device receives power from the power supply device, based on the criticality information and the power supply information.
