There were no injuries as a result of the incident and the area has been secured, Vestas said in a statement.

“Vestas experts have initiated the investigations in close cooperation with the customer to determine the root cause of this incident,” it added.

The company declined to give further comment “until our technical experts have preliminary findings from the root cause analysis”.

Vestas was contracted to supply and install 17 V150-4.2MW turbines with 155-metre hub heights at Aldermyrberget.
