Early warning for grid anomalies, days before the event.
Real-time, unsupervised anomaly detection for power grid telemetry. Validated against six years of public ISO data across CAISO, ERCOT, and NYISO.
What it does
HTM-Monitor watches a grid's own telemetry — demand, net generation, forecast error, imbalance — and flags when the system is behaving in ways it hasn't behaved before. No fixed thresholds. No supervised training. The model learns each operating signature as it runs and raises a signal when real-time data departs from the learned envelope.
The goal is simple: surface grid stress early enough to matter, before fixed thresholds tuned for last season's fuel mix catch the event retrospectively.
Validation — targeted reliability events
| Event | ISO | Detection |
|---|---|---|
| Winter Storm Uri | ERCOT · Feb 2021 | 98 h ahead |
| Sept 2022 heat emergency | CAISO · Sept 2022 | 108 h ahead |
| Aug 2020 rolling blackouts | CAISO · Aug 2020 | 7 h into event* |
*Onset detection rather than forecast — flagged once the event was underway. Full methodology, per-ISO results, and complete alert logs available on request.
How it works
The engine is Hierarchical Temporal Memory — a biologically-inspired sequence-learning algorithm — extended with a grouped-consensus decision layer that only raises a system-level alert when multiple independent signals agree. Unsupervised, online, and auditable per step.
Runs single-process in Python 3.9+. No GPU. No external calls. Deploys on a $5/mo VPS or inside an air-gapped VM — operator's choice.
Ways to start
Technical preview — free. Send a 90-day telemetry sample and one past event you'd like scored. You get a preview audit inside a week: lead/lag, false-positive rate, per-signal notes. No commitment.
Paid pilot — $2,500. Full historical replay against your events, with a written per-event audit inside a week. The fee credits in full against your first month of subscription.
