Test Site Lelystad – a full service wind turbine testing facility – provides a comprehensive range of facilities for prototype testing, infrastructure, wind measurements and wind turbine testing services. With 12 positions for wind turbine prototyping and certification measurements and a combined installed power of 30 MW, this is the largest Test Site in Europe.
On-site wind measurements are essential in determining the wind regime of a site and consequently the feasibility of an under-development wind farm. Moreover, wind measurements are also used for the performance assessment of operating wind farms. Ecofys WTTS, building on a 15-year track record of measurements performed in Europe, Central and northern America and Middle-East Asia, provides worldwide wind measurement services.
At Test Site Lelystad, The Netherlands, Ecofys WTTS offers state of the art validation and verification tests for LiDAR and SoDAR remote sensing systems. For this purpose a fully IEC-compliant 120 m tall mast is available with four measurement heights between 40 and 120 m (40, 80, 95 and 120 m).
Ecofys WTTS’ engineers can carry out additional detailed analysis of local wind characteristics, such as:
- Local features (e.g. strong wind shear, reverse flows),
- Extreme events (e.g. gustiness),
- Stability effects (e.g. low-level-jets)
