A wind turbine fell to the ground at the Kent Hills wind facility in Albert County this week.
TransAlta says no one was hurt and the cause of the incident is under investigation.
For recreational users, company spokesperson James Mottershead says the area surrounding the wind facility has been closed.
TransAlta is asking the public to avoid the wind farm which includes all turbines, substations, collector lines and access roads.
The company adds an update will be provided once the site has been deemed safe again.
