As part of planning and project development, the site-specific wind potential is not only the basis for creating bankable yield assessments for financing, but also serves as the foundation for evaluating site suitability and proving site quality for commissioning according to EEG 2017, including the assessment of losses.
As a testing laboratory flexibly accredited according to DIN EN ISO/IEC 17025:2018 under Category III, we actively participate in specialized committees and are involved in the development of guidelines. The assessment of long-term wind conditions and the forecast of energy yields for planned wind turbines are carried out using recognized analytical methods. The basis is the Technical Guideline for Wind Turbines, Part 6 "Determination of Wind Potential and Energy Yields" (TR6) by FGW e.V. - Association for the Promotion of Wind Energy and Other Decentralized Energies in its latest revision. A list of current and verified standard editions can be found here.
Complex sites require complex models. For wind turbine locations situated in mountainous terrain, the determination of wind potential and expected energy yield is additionally based on three-dimensional, non-linear flow models, known as CFD models (Computational Fluid Dynamics). We review the available data according to the specifications of TR6 and advise you on the complex requirements and relationships concerning your wind farm planning.
Our bankable yield assessments include a detailed analysis of uncertainties. Additionally, we are happy to calculate the expected energy yield losses in cases of, for example, environmental protection requirements (species protection, shadow flicker, or noise emissions, etc.) and report them accordingly.

With the help of LiDAR devices, wind speeds and wind directions are measured at heights of up to 200 meters. The wind measurement serves as the basis for determining the site-specific wind potential.
