Shutting down wind at night to protect bats

Duke Energy Renewables voluntarily conducts daily wildlife checks at our North Allegheny Windpower Project in Pennsylvania. During a routine survey last fall, a bat carcass was found. An expert summoned to the site confirmed that the animal was a federally protected Indiana bat, an endangered species.

We immediately notified federal and state wildlife officials, and voluntarily implemented an Adaptive Management Protocol — suspending nighttime operations through mid-November, when bats typically begin hibernating.

Duke Energy is working closely with the U.S. Fish and Wildlife Service and the Pennsylvania Game Commission to develop a long-term plan to mitigate the wind farm’s impact on bats, particularly during migration season.

Although the company lost revenue by temporarily suspending nighttime operations at the 70-megawatt wind farm, it was the right thing to do.
