SCADA Event Log Monitoring & Grid Reliability Anomaly Engine
95% anomaly-detection accuracy on the engagement evaluation set and 60% faster NERC CIP / FERC filing preparation — medallion processing of SCADA event logs with AI incident summaries.
Buyer Objection
During an engagement supporting expansion into energy and utility accounts, grid operators were drowning in raw SCADA event logs while NERC CIP and FERC filing pressure mounted. Utilities buy slowly and conservatively — the platform needed operational value and regulatory relief proven in one architecture. Role: Field CTO & technical GTM lead, light-touch.
Architecture Thesis
Utilities buy slowly and conservatively. Medallion processing of SCADA event logs with anomaly detection and natural-language incident summaries proves operational value and regulatory relief in one architecture — the summary an operator reads is worth more than any dashboard.
Reference Architecture

The engine ingests streaming substation event logs (SCADA_Event_Log) into a Medallion analytics engine. Silver processing maps device IDs and normalizes error codes, while Gold models execute time-series anomaly detection and supply incident contexts to an operational LLM summarizer. Grid topological stability is quantified via:
Preconditions & Assumptions
- Event-log taxonomy and time-series baselines established per substation class.
- NERC CIP / FERC record requirements mapped to the data path.
- Ground-truth incident history assembled for model evaluation.
Control Model
- Human review of flagged anomalies before operational action — the model advises, the operator decides.
- Drift monitoring on detection models with retraining triggers.
- Regulated-record retention and access controls on the filing data path.
Validation Plan
- Detection accuracy measured on a defined evaluation set with ground truth; false-positive and false-negative tradeoffs documented and accepted by operations.
- Filing-preparation time measured against the prior manual compilation process.
- Incident summaries reviewed by field engineers for operational accuracy.
Quantified Outcomes & Methodology
All figures are engagement outcomes from the anonymized engagement described above — no external benchmarks cited.
Scope & Methodology
Methodology: accuracy measured on the engagement's evaluation set against ground-truth incident history, with human review of flagged events; filing-preparation reduction measured against prior manual compilation. Model performance is reported separately from business outcomes — detection accuracy does not itself guarantee reliability improvements.
Risks & Non-Goals
- Model accuracy decays with grid changes — drift monitoring is a control, not an option.
- False positives carry real dispatch costs; the FP/FN tradeoff is an operational decision owned by the utility.
- Automated summaries support, but do not replace, regulatory record review.
Rollout Approach
- Stage 1: shadow-mode detection alongside existing monitoring.
- Stage 2: operator-in-the-loop alerting after accuracy acceptance.
- Stage 3: automated record compilation for filings after audit dry run.
Executive Takeaway
Particularly effective in conservative infrastructure sectors, where a natural-language incident summary is worth more than any dashboard.
