A brown out prediction system is provided that performs validation, estimation, and editing (VEE) on a plurality of interval based energy consumption streams. The system includes a post VEE readings data stores, a rules processor, a peak prediction element, and a peak controller. The post VEE readings data stores is configured to provide a plurality of tagged energy consumption data sets. The rules processor is configured to read the post VEE readings data stores and is configured to create a plurality of anomalies having a plurality of differnt durations. The peak prediction element is coupled to the post VEE readings data stores and to weather stores, and is configured to receive post VEE readings. The peak controller is coupled to the peak prediction element, and is configured to receive the brown out time, and is configured to trigger exceptional measures to manage the cumulative energy consumption in order to preclude a brown out.
