Utility meter anomaly detection

actual vs learned baseline

Domestic water — Tower A
hour-of-week baseline · 8 weeks
Anomaly
48.2 kL/h
baseline 36.8 · +31.0% · z 3.1
Sustained overnight flow suggests a riser leak or stuck float valve.
Grid load — Main incomer
hour-of-week baseline · 12 weeks
Anomaly
1,120 kW
baseline 940 · +19.1% · z 2.4
Chiller staging overlapped with EV charging peak.
Solar yield — Rooftop PV
irradiance-adjusted baseline
Watch
118 kWh
baseline 164 · -28.0% · z -2.0
String 4 output 28% low — soiling or inverter derate likely.
Common area energy
hour-of-week baseline · 8 weeks
Normal
402 kWh
baseline 412 · -2.4% · z -0.3
Within learned band; lighting schedule tracking as expected.
STP reuse line

baseline 30.1 · -25.6% · z -1.9
Reuse dropped after pump 2 tripped; irrigation on fresh water.

Detection model

NX-Sense

Detector: NX-Sense · seasonal-hybrid ESD + EWMA
Baseline: Hour-of-week, 8–12 week trailing
Sensitivity: z ≥ 2.0 watch · z ≥ 2.8 alert
Retrain cadence: Nightly 02:00, drift-checked
Warm-up: 14 days per new meter
False positive rate: 3.4% (30d rolling)

How alerts fire

Each meter learns an hour-of-week baseline. Deviations past the sensitivity band raise a utility-domain incident with the deviation, z-score and probable cause attached for acknowledgement or escalation.
