Turbine manufacturer Vestas and developer EDPR are investigating a blade failure at the Timber Road 4 wind farm in the US state of Ohio.
A blade on a V150 4.2MW was heavily damaged in the incident. No one was injured.
In a joint statement, the companies said the site was secured after the failure, which occurred on 3 September.
“Following the occurrence, Vestas and EDP Renewables completed a site wide inspection of the blades on the other 30 wind turbines at Timber Road IV Wind Farm, and no additional damage nor indication of other failures were found,” the companies said.
“The full backing and resources behind Vestas will be focused on the investigation, and at this time, Vestas and EDP Renewables personnel are assessing the turbine blade damage and have conducted meetings with management teams to discuss a path forward.”
The blade will be replaced at a date to be determined, and the turbine will return to full-service, added the statement.
“We cannot speculate on the cause of the incident and are conducting a root cause analysis to evaluate what may have caused the incident.
“EDP Renewables is also working closely with the Ohio Power Siting Board and local law enforcement on its public safety response efforts, and as appropriate, will share more information as the investigation occurs.”
