The rotating rotors of wind turbines constitute a risk to bats if the turbines are operated without mitigation measures. To date, there has been no scientific derivation for a significance threshold that can be used as a basis for nationwide uniform regulations for shutdowns to protect bats. Within the project, a scientific draft for rationale a significance threshold for bats and wind turbines was presented, based on scientific literature, administrative regulations, and court rulings. This proposes a nationwide threshold of < 1 animal per turbine per year.

The publication thus represents a professionally validated contribution to the discussion and standardisation, with the aim of expanding wind energy use in the most environmentally friendly way possible.

Furthermore, the publication contains shutdown requirements differentiated by region and season, which will allow the shutdown of wind turbines to be reduced even more precisely to the necessary level in the future to protect bats.
