The study "Economic aspects of event-related shutdown for bird protection at wind turbines. Breeding site scenarios - yield losses - influence on turbine technology" by Reichenbach et al. (2020) provides information on the yield losses in electricity production to be expected when anti-collision systems are used for bird protection at wind turbines. The authors also developed exemplary scenarios for the red kite in order to estimate the number of shutdowns per day based on selected parameters of the turbine location. The annual yield losses due to the event-related shutdown based on the determined flight activity scenarios amount to an average of 0.4 to 2.3 to percent at the six German study sites. The yield losses are thus significantly lower than those of a blanket shutdown (28.6 per cent on average).
Bird protection and anti-collision systems
How can the expansion in renewable energies be designed in harmony with nature? The Federal Agency for Nature Conservation (BfN) is providing expert scientific advice on this question to the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety (Bundesumweltministerium, BMUB). Research by the BfN always has a practical application and generates scientific results for advising government i.e. supplies a basis for decision-making for the preparation, implementation, monitoring and further development of nature conservation measures and the Federal Government's nature conservation policy.
