Noise reduction

In wind power, so-called Trailing- Edge-Serrations (TES) have established themselves as the state-of-the-art solution for reducing noise emissions.

WTS has developed a new type of 3D geometry for TES, which enables significantly higher noise reduction of up to 6 dB(A), compared to the previously used geometries (based on 2D designs with isosceles triangles).

Noise emissions from wind turbines are one of the greatest restrictions on the expansion and repowering of onshore wind energy. Recent amendments to the law currently even endanger the realisation of already planned projects due to the new stricter guidelines for calculating the actual noise emitted (LAI guidelines). As a result, for example, wind turbines must be operated in reduced night mode, resulting in a yield loss
of 3 - 6 %.

WTS Serrations are intended to help restore planning reliability and even improve the yield of wind turbines in noise-sensitive locations.
