Dokumentation Fachgespräch „Antikollisionssysteme für Vögel“ - Ein Blick auf den Entwicklungs- und Erprobungsstand.
What progress has been made in the further development and testing of anti-collision systems? Does the current status of selected systems allow their use in practice? If so, below what conditions and for which bird species? How can anti-collision systems technically be certified? The KNE technical discussion "Anti-collision systems for birds - ready to take off?" with 160 participants on July 7, 2021 addressed these and other questions.
As early as 2019, a KNE specialist conference on the subject of "Bird protection on wind turbines" took place in Kassel. There, among other things, various camera and radar systems and ongoing test projects are presented. This year's expert discussion served to refresh the level of knowledge about the system development and to present the first comprehensive test results for discussion. In the following chapters the contents of the event are reproduced and supplemented by the KNE.
Anti-collision systems have the potential to reduce the significantly increased risk of killing wind energy-sensitive bird species to such an extent that species protection legislation prohibition is not met. You can use an alternative to a longer-term "blanket" day off during the breeding and reproductive season (so-called phenology-related shutdown). An automatic demand-based switch-off using anti-collision systems could reduce the loss in electricity production compared to a general shutdown. The probability of effectiveness of anti-collision systems depends largely on their performance. This must be demonstrated through a systematic testing in the field. The test results should be published and checked by independent third parties. The KNE has one "Requirements profile" (KNE 2019a) formulated for a scientific implementation and documentation of test projects. This provides guidance for test project.
