Wind Resource Information

SWERA wind products provide estimates of how much wind resource is available at potential development sites. SWERA wind resources are depicted as average wind speed (meters per second) or wind power density (watts per square meter) at a specified height above the ground (nominally 50 m). These are derived from models and satellite and global weather observations and do not contain site-specific data. The SWERA high-resolution (such as 1-km and 5-km) gridded data products allow for identification of resource rich areas that could be missed in lower resolution data sets. The SWERA wind products can be used to determine what areas warrant further investigation for wind development. These products are not intended to be used for siting decisions, especially wind farms, but instead should be used to identify potential areas for wind farms at which more detailed time-series site-specific data should be collected.

Wind Resource Maps

Example of Wind Resource Map

The SWERA wind maps provide visual presentations of how much wind energy is available at potential development sites. These maps can be used to visually identify areas rich in wind resources within a country or region, and allow an easy look at the data without the need to navigate through large data sets or applying GIS software. For more detailed investigations, users should explore the wind data sets available through the SWERA database.

Wind Data Products

Example of Wind Product

The SWERA data sets allow users to compare the resource availability of different regions and to compare the resource availability of different regions, and to develop preliminary analysis of wind energy production for various types of turbines. Before using these data in analyses, please confirm the data required by your wind energy simulation algorithm (wind speed, wind power, height above ground, etc.) and make adjustments as necessary.
