A blade that had come loose was the cause of the collapse of a Vestas turbine in the Swedish wind farm Aldermyrberget on November 22, Vestas informs SVT.SE.

- One of the blades came loose, which made the wind turbine so unstable that it collapsed, says Anders Riis, Head of Communications at Vestas.

Vestas has delivered and installed 17 V150-4.2 MW wind turbines to Aldermyrberget, but has not yet handed over the project to the customer WPD Scandinaiva.

The turbines were supposed to have been commissioned in December, but are still standing still as Vestas wants to conduct further investigations before commissioning. 

- We are still investigating why the accident occurred. We want to know as soon as possible, but it is too early to say, says Anders Riis.

The wing that caused the terrible accident has now been sent to the UK for further examination.

You can see a video of the accident scene on STV's website.
