Last month, Dundonnell was also hit by a fallen blade at one of its Vestas turbines, which brought production across the wind farm to a halt for a few days as the cause was investigated. Campbell says it is clear that the blade fell because bolts holding it to the hub became loose, but the question of why those bolts became loose is still under investigation.

Tilt Renewables’ massive Dundonnell wind farm in Victoria is gradually powering back up one week after the project was shut down after a 73 metre, 70 tonne blade fell off one of the project’s 80 newly installed Vestas turbines.
The blade fell around 8.30pm and the company has since removed all turbines from operation while an investigation of the damage occurs. "A root cause analysis will be completed in conjunction with the wind turbine manufacturer, Vestas, which will inform the assurance process on the other turbines prior to these being returned to service," Mr Campbell said.
It's estimated the blade came adrift around 6:40pm, the same time as the storm passed through the area. It's not yet known if the storm caused the turbine to break. The Lal Lal Windfarm consists of 60 Vestas V136-3.6 MW. The 228 MW facility was placed in service around June 2019.
Several Queensland Fire and Emergency (QFES) crews attended the blaze, which ignited about 3pm. A QFES spokeswoman said crews stood by for safety in the event that it led to a grass fire.
