A system and method for managing the power consumption of power-consuming devices. A remote device manager transmits power save schedules to a local device manager over a communication network such as the internet. The local device manager transmits power save commands to one or more devices in a location such as a store, over a dedicated local communication network. The commands instruct one or more devices to activate or de-activate its power save mode according to the power save schedules. The commands could be dependent upon one or more trigger events.
