Wind turbines have been shown to cause direct mortality to bat species, with bat deaths documented at wind energy facilities around the world. Building upon insights from nature and a great deal of previous research, NRG Systems developed its Bat Deterrent System to mitigate the wind industry's impact on bats. This white paper provides an overview of the development of this pioneering solution.

A robust validation study design, carried out prior to Bat Deterrent System installation, can yield statistically reliable results that provide a preview of what success could look like at a wind site. This paper will cover some of the study designs that NRG Systems is aware of, including the benefits and drawbacks of each method.
