Bat Protection System (BPS)

Topwind has developed its Bat Protection System in close cooperation with ecologists and bat experts. The primary goal is protecting bats while minimizing energy production losses. Competent authorities currently issue an exemption permit after presenting sufficient proof that appropriate measures were indeed taken to reduce bat victim numbers.

BPS Monitoring

Once a bat exemption permit is issued, you are still obliged to conduct monitoring. Risk mitigation itself is realized via non-operation algorithms imposed by competent authorities. Monitoring implies the registration of bat activity with an ultrasound microphone located within the nacelle base near the rotor. Registered data are stored directly on a hard disk as part of a distance monitoring package.

BPS Protection

For minimizing the number of bat victims in protected areas, wind turbines will be switched off on the bases of specific non-operation algorithms. This is performed by two different methods:

1. Weather and time-based protection via an automated start/stop function, which operates with pre-programmed time blocks and specific preconditions like temperature, light intensity, and wind speed;
2. Real-time protection via an automated start/stop function is based upon actual detection, but as a method still in development. This option could be introduced at a later stage provided it contributes significantly to reduce power production losses.
