What happened
A wind turbine at PORTA High School in Petersburg, Illinois, was reported to have suffered a brake-system failure, so the blades could spin freely. Specialised technicians could not work on it until the blades stopped, which would require the wind to die down or a further equipment failure. The following day the sheriff's office and the local fire department reported that the turbine had collapsed. It stood away from homes and public areas, and no one was hurt. The public was advised to stay away.
Contributing factors
Officials reported a failure of the brake system. Why the brake failed, and why the turbine then collapsed, were not reported.
Lessons learned
- A reported brake failure that leaves blades free to spin can prevent technicians from making the turbine safe until rotation stops.
- Sites need a plan for exclusion and specialist access when a turbine cannot be stopped at once.
- Keeping turbines away from homes and public areas, and warning people to stay clear, limited harm in this case.
