Actionable insights

01Deploy as a weekly scoring job

Score the fleet every week and push flagged generators straight into the maintenance work-order queue as priority repairs.

02Tune the alarm threshold to cost, not to 0.5

Lowering the decision threshold trades a few extra inspections for fewer missed failures — the cost ratio says that trade is worth making.

03Instrument V18, V21, V15 and V7 more closely

These carry the strongest failure signal; higher sampling frequency on the corresponding subsystems should sharpen the model.

04Keep a human review step

Technicians confirm flagged units before a repair is scheduled, and their verdict becomes labelled data for the next training round.

05Retrain quarterly and monitor drift

Sensor behaviour changes with turbine age, firmware and weather; track recall and false-alarm rate every month.

Limitations & future work

Ciphered features limit interpretability

V1–V40 cannot be mapped to physical components, so root-cause explanation needs ReneWind's internal sensor dictionary.

Single snapshot per generator

The data has no time dimension; sequence models on rolling sensor windows should detect degradation earlier.

Cost figures are assumptions

Real repair, replacement and inspection costs would let the decision threshold be optimised directly on expected cost.

35 failures still missed on test

Threshold tuning, ensembling several networks, and focal loss are the next levers to try.

Model drift and fairness across sites

Turbine model, age and climate may shift the distribution; monitor recall per site and retrain quarterly.

Scaling the impact

Catching a failure early converts a replacement into a repair — that swap is where all of the value sits. Scaling to a fleet of 50,000 generators, the same ratio implies roughly $110M of avoided maintenance cost per scoring cycle.
