Wind Energy Analysis estimates the power output of wind turbines placed at locations in your project. Provide a point dataset of turbine locations, choose a turbine model, and Atlas calculates the expected energy yield. The tool also visualises each turbine in 3D on the map and can draw fall-zone and buffer-radius layers around them.
Open the tool
Open the right-hand panel, switch to the Tools tab, and select Wind Energy Analysis. The tool automatically enables 3D mode so turbines render at the correct elevation.
Inputs
- Input — a vector dataset containing the turbine points. Other geometry types are not supported.
- Hub height — height of the turbine hub above ground. Default is 125.5 m for Vestas, 85 m for Enercon.
- Rotation — rotor rotation in degrees, 0–360°.
- Choose wind turbine — pick a turbine model from the manufacturer list. Default is the Vestas V136-3.45 MW.
- Number of turbines placed — read-only count derived from your input dataset (max 200).
Buffer layers
After loading turbine points you can toggle two visual layers around each turbine:
- Turbine fall layer — a circular fall zone with radius equal to the turbine's hub height.
- Buffer radius — a custom buffer around each turbine (default 500 m). When enabled, set the radius with Specify buffer radius for each turbine.
Run
Click Calculate to send the configuration to Atlas and compute the power estimate.
Reading the result
A popup displays the estimated annual energy yield and the per-turbine outputs given your chosen turbine model and hub height. The 3D turbine models stay visible on the map until you switch tools or close the panel.
Limits and notes
- The tool requires 3D mode and turns it on automatically when opened.
- The input dataset must contain Point geometry; other types are filtered out before calculation.
- Up to 6 000 features are loaded from the input dataset; the calculation is capped at 200 turbines.
- Wind resource data is sourced from the Global Wind Atlas.
