Abstract

Significant changes in monitored and reported operational parameters and/or power outage events occurring in a utility'"'"'s electrical power transmission/distribution grid are correlated with historical, current and/or forecast weather events based on potential root cause, geographic and temporal constraints. Operational event and outage information is collected and time-stamped using a communication network of devices and sources that monitor and report, among other things, equipment parameters, electric power availability and outages. A computer-implemented root cause analysis engine (RCA) operatively associated with a computer-implemented weather data correlation engine sorts and analyzes operational parameter/event information and identifies probable correlations to localized weather phenomenon. Operational parameters/events are then displayed using a graphic display device in a manner that enables user controllable and configurable viewing of a time-lapse evolution of weather phenomenon overlayed with graphics representing both weather-related and other relevant operational parameters/events depicted in relation to the utility'"'"'s physical infrastructure.
