How To Conduct A Wind Resource Assessment?

Choosing a Measurement Technique

To assess a wind resource, you can use either a fixed anemometer tower or a mobile measurement unit. A fixed anemometer tower is more accurate but requires a larger footprint and is typically more expensive. Mobile measurement units can be deployed quickly and at a lower cost but may not provide as accurate results. Consider using a wind speed measurement tower at a height of 50-100 meters (164-330 feet) above ground level.

Analyzing Weather Data

You can obtain weather data from local weather stations, wind maps, or satellite imagery. Wind maps provide a general overview of wind speeds and directions across a region, while local weather stations provide more detailed information on temperature, humidity, and wind speed. Analyze the data to determine the average wind speed, wind frequency, and wind direction. A wind speed of at least 7 meters per second (15.6 miles per hour) is generally considered suitable for wind power generation.

Evaluating Topographic Features

Topographic features such as hills, ridges, and valleys can significantly affect wind patterns. Analyze a topographic map of the site to identify any features that could either enhance or block wind flow. Consider using a wind rose diagram to visualize the wind patterns and identify any areas of high wind speeds. A wind rose diagram is a graphical representation of wind direction and speed, which can help you identify the most suitable locations for a wind turbine.
