Quebec introducing new rule to reduce bat deaths linked to wind farms

Dec 21, 2023 | 10:04 AM

Quebec’s Environment Department says it is introducing a new measure to mitigate the impact of wind farms on bats native to the province.

The government will require all future wind farm projects to increase turbine cut-in speeds — when the blades start rotating and generating power — to 5.5 metres per second at night between June 1 and Oct. 15.

Those months coincide with the period of the year when bats are most active in North America — and when they are most often killed by turbines.

The department says the measure has proven effective elsewhere and should significantly reduce the risk of bats colliding with turbines in Quebec, the second-largest wind energy market in Canada, after Ontario.
