Cost-Effective WRF Mesoscale Modeling

Mesoscale modeling tool for Wind Resource Assessment

A new trend of the wind industry is to use mesoscale techniques to identify sites, but also to perform long-term correlation with on-site masts and run wind power forecasts on operating wind farms. In the past few years, a number of mesoscale data providers have entered the market to provide clients with simulated historical data or wind maps at any location.


This technology has now been developed as a software product, called the ZephyWDG (Zephy Wind Data Generator).


This user-friendly tool can now be used in-house by wind energy engineers who are given the ability to tune the model (computation resolution, roughness length, simulation heights) according to their own requirements.


Moreover, as wind farm development information are more and more confidential -especially during the very sensitive stage of site prospection- this tool enables them treating their existing or upcoming assets with the highest regard to confidentiality without sharing information with third party companies.
