Those high winds last Friday that knocked down tree limbs and power lines, also damaged a wind turbine at Bruce Power.
Gusts of about 100 km/h rolled in off Lake Huron around 3pm that day, and one of the tips on a turbine was broken.
Bruce Power Manager of Communications and Media Relations, John Peevers says as soon as the issue was noticed, the 5 wind turbines jointly owned by Bruce Power and its partners were turned off.
Bruce road 20 was also closed in the area of the Visitors Centre, which is close to the turbine that was affected.
Peevers says the Huron Wind project is 12 to 15 years old and there has never been an issue like this.
The turbines remain idled while workers investigate whether the 4 others are safe, and while repairs are done to the one wind turbine.
Peevers says Bruce road 20 remains closed and won't likely open until later this week.
