Wind Measurements

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.
