Abstract
In accordance with the West Virginia Public Service Commission (WVPSC) and with guidance from the Technical Advisory Committee, which included members from the WVPSC, U.S. Fish and Wildlife Service, West Virginia Division of Natural Resources, and Edison Mission Energy, we initiated a study in July 2012 to test the effectiveness of an operational mitigation experiment to reduce bat fatalities at the Pinnacle Wind Farm (PWF), Mineral County, West Virginia. Our objective was to determine the difference in bat fatalities at turbines with different operational adjustments. A post-construction fatality monitoring study was conducted at the PWF between 1 March and 30 November 2012, results of which are discussed in a separate report.
