title: Platinum Mine — Pumping & Ventilation Optimization sector: Mining location: Southern Africa baseline: High peak demand and unplanned downtime on critical pumps. intervention: Sensor fusion + edge models for predictive maintenance; setpoint tuning. outcome: 12% energy intensity reduction; 18% downtime reduction (6 months). roi: Payback in ~9 months

We deployed secure gateways to stream SCADA and sensor data, trained digital twins for key pump trains and ventilation fans, and implemented alerting + playbooks for operators.
