Grid stability monitoring relied on processing approximately 9% of sensor events in real time, with the remainder batch-processed for trend analysis. The early signatures of instability — subtle correlations across geographically distributed sensors — required full spatial and temporal coverage to emerge. Events that resulted in unplanned outages were consistently preceded by patterns that existed in the full sensor stream hours before the instability became visible in sampled monitoring.
Full sensor event coverage across the monitored grid infrastructure. LLM reasoning configured to identify spatial correlation patterns across distributed sensors — signatures that require full coverage to become statistically significant.
"Six hours of advance warning on a grid event is transformational. The signal was always there. We just couldn't afford to process enough of it to see it."

The most significant early finding was a class of instability signatures that manifested as correlated micro-deviations across clusters of 8-12 geographically adjacent sensors. Each individual sensor reading was within normal parameters. The spatial correlation only emerged at full coverage. This pattern class preceded 91% of the major unplanned outages in the prior 24-month historical record.
