What happened
A wind turbine at the Raleigh Wind Power facility in Raleigh Township, Ontario, collapsed earlier in 2026, according to a National Post report published on 12 October 2026. According to TerraForm Power, a single faulty blade caused the collapse. The facility returned to service on 28 March. The exact date of the collapse, the number of turbines affected, and any injuries or damage beyond the turbine were not stated in the material available.
Contributing factors
TerraForm Power attributes the collapse to one faulty blade. No other contributing factors were reported in the source material available.
Lessons learned
- A defect in a single turbine blade can lead to turbine collapse, so blade condition and root attachment should be part of structured inspection regimes.
- Return-to-service decisions should be supported by a documented root cause and checks of the affected components before restart.
- Operators should publish or share root cause findings with enough detail to allow other owners to check their own fleets for the same fault.
