The U.S. Department of Energy (DOE) is proposing to provide federal funding to Frontier Wind to design and develop an ultrasonic transmission system to prevent fatal bat interactions with wind turbines, assess the effectiveness of the installed system, create processes for retrofitting operational turbines and installing on new wind turbines during manufacturing or construction, and create system controller settings optimized for a range of bat species.

Task 1 activities would include completing a bat fatality and activity literature review and summary report for the Hatchet Ridge Wind Farm, gathering wind turbine design information to establish potential ultrasonic deterrence system installation locations, develop the ultrasonic deterrence system specifications, and plan ultrasonic system testing. Administrative, research, design and planning activities would be performed by a third party consultant and by Frontier Wind at their offices in Rocklin, CA.
