Abstract: Disclosed herein are a smart plug-based power management method for preventing a power failure and an apparatus for the method. The power management method includes acquiring load amount information for each of multiple loads corresponding to power management targets, checking a maximum amount of power that is capable of being generated by a solar power generator, setting a power supply mode based on at least one of whether power is being supplied from a power system and a result of a comparison of the load amount information with the maximum amount of power, and performing power management so as to prevent a power failure by interrupting a supply of power so as to correspond to the power supply mode based on multiple smart plugs for controlling corresponding ones of the multiple loads.
