This episode cuts through the marketing to assess where digital twin technology has produced verifiable results in energy infrastructure — and where it systematically fails.
Key findings:
— GE Vernova SmartSignal: $1.6B in avoided unplanned downtime across 7,000+ assets
— Siemens Gamesa / NVIDIA PhysicsNeMo: 4,000× CFD speedup, 3% AEP improvement via wake optimisation
— Industry average: 30% maintenance cost reduction and 20% asset life extension where deployed correctly
— Under 15% of digital twin projects reach full operational maturity
The article examines the four failure modes most deployments encounter: model drift in aging assets, sensor data quality collapse, blindness to novel failure modes, and the gap between high-fidelity demo models and the reduced-order models actually running in operations centres.
Africa section: why 4.5 GW of solar installed in 2025 was largely commissioned without the sensor infrastructure that makes digital twins useful — and what the correct engineering investment sequence looks like.
