Enercon has launched an investigation into the collapse of a turbine at the 23.3MW Point Tupper wind farm located close to Port Hawkesbury in Nova Scotia, Canada.
The German turbine manufacturer said the incident, which occurred during a component exchange last Wednesday, triggered an evacuation alarm before the turbine collapsed and that nobody was injured.
The wind farm was developed by a joint venture between Canada’s Renewable Energy Services, which is the controlling shareholder, and Nova Scotia Power.
It uses Enercon E-82 and Enercon E-48 turbines, although Enercon did not specify which model was involved in the collapse.
“With close to 1000 wind turbines installed in Canada over the course of the last 15 years, this is the first time that such an event has occurred,” Enercon said in a statement.
A technical team is probing the incident, which did not occur during regular operations and is “undoubtedly an isolated one”, Enercon said.
The rest of the wind farm continues to operate safely, it added.
