What happened

A blade on a Vestas V150 4.2MW turbine at the Timber Road IV wind farm in Ohio suffered heavy damage in a failure on 3 September 2020. No one was injured. Vestas and EDP Renewables secured the site and conducted a site wide inspection of blades on the other 30 turbines at the wind farm, finding no additional damage or indication of other failures. The companies stated they could not speculate on the cause and were conducting a root cause analysis.

The damaged blade will be replaced at a date to be determined, after which the turbine will return to full service. EDP Renewables said it was working with the Ohio Power Siting Board and local law enforcement on public safety response efforts.

Contributing factors

Not reported; a root cause investigation was underway at the time of reporting.

Lessons learned

After a blade failure on a Vestas V150 turbine, operators should inspect blades on all turbines at the site to rule out a shared fault.
Following a blade failure that may affect public safety, the operator must work with local regulators and law enforcement on response.
