How do we work?

Check out the quality of the work we did here.

Tools:

• In-house tools for wind data validation and statistical analysis as well as generic reporting;
• In-house tools for uncertainty assessment;
• WAsP, openWind, WindFarm, WindSim – tools used for wind farm design;
• Didger, Surfer, MicroStation PowerDraft – GIS tools.

Supplementary data sources:

• ERA-Interim, NCEP CFSR, NASA MERRA, NCEP NCAR, in-house resources – for accurate wind climate predictions;
• CORINE Land Cover – terrain roughness database;
• Geoportal, CODGiK – maps.
