In a release on Canadian news wire CNW Telbec, Enercon said the incident occurred on 17 August during a "scheduled component exchange".
One of the site's E82 2.05MW turbines collapsed during the scheduled maintenance. Investigations are ongoing to determine the exact cause of the collapse.
"An incident triggered the Enecron evacuation protocol. The technician on site diligently followed such protocol and safely evacuated the turbine and the surroundings in time to avoid any injuries prior to the turbine's collapse. Only property damage has been reported," the release said.
Enercon described the incident as "isolated" saying it is the first time such an event has happened to one of its 1,000 turbines installed in Canada.
"This incident did not occur during regular operations and is undoubtedly an isolated one," Enercon said in the statement. The affected turbine has been disconnected, but the site's remaining machines are continuing operation.
According to Windpower Intelligence, the research and data division of Windpower Monthly, Point Tupper comprises 11 Enercon E82 2.05MW turbines and was completed in 2006. In 2010, a single E46 800kW turbine was added to the site.
It is owned by local developer Renewable Energy Services (RESL).
