Abstract

A system, an alternative system, and a computer readable storage medium, for a power outage notification system that proactively manages communication of power outage alerts messages to customers of a power distribution system. Wireless communications between smart meters at the edge of an electrical power distribution network and a proactive outage alerts processing engine at an outage alerts notification information processing system facilitate management of communications of power outage alerts messages to customer communication devices. Power outage alerts messages can be communicated to customers using email messaging, text messaging, and voice mail messaging.
