Problem
Unplanned outages across a distributed generation estate, with maintenance scheduled on fixed intervals regardless of asset condition.
Solution
Condition monitoring over existing SCADA telemetry, with failure signatures built from three years of historical outage records.
Result
Unplanned outage hours down 23% year on year. Maintenance visits down 18% through dropping fixed-interval work on healthy assets.
Kestrel had the telemetry. What it did not have was a link between the telemetry and the outage records, which sat in a different system with a different asset identifier.
How the work ran
- Three years of outage records reconciled against telemetry history — six weeks of work that made everything after it possible.
- Failure signatures derived per asset class rather than one model across the estate.
- Alerts routed into the existing maintenance workflow, not a new dashboard nobody would open.
- A deliberate false-positive budget agreed with the field team, because an alerting system they stop trusting is worse than none.
What made the difference
The field team set the false-positive tolerance and reviews it quarterly. That is why the alerts still get actioned two years on.
“The discovery was fixed price with a fixed end date, and the recommendation was something we could have taken to another firm. We did not need to.”
