Wind-farm pre-assessment in QGIS: Energy/AEP, Noise and Shadow Flicker workflows.
Open-source QGIS plugin for early-stage wind-farm pre-assessment. It includes Energy/AEP workflows, wind-turbine noise screening and shadow flicker analysis. This stable package targets QGIS 3.28 through 3.x. QGIS 4 requires further manual validation and is not declared for this build. Important installation note: the Energy/AEP module requires PyWake to be installed separately in the same Python environment used by QGIS. PyWake is not a QGIS plugin and will not appear in the QGIS plugin manager. On Windows, open OSGeo4W Shell and run: python -m pip install py_wake==2.6.18 "h5netcdf>=1.8". Then restart QGIS. Since version 1.8, h5netcdf no longer depends on h5py, so this command does not install h5py through h5netcdf. h5py is needed by the GaussianOverlapAvgModel rotor average; see the OSGeo4W installation guide for the untested OSGeo4W package option. XML turbine imports (.wtg and .owtg) use a bundled safe XML parser and need no additional package. Noise and Shadow Flicker can be tested independently without PyWake. This release is intended for screening, layout comparison, workflow testing and technical feedback. It is not certified regulatory or bankable assessment software. Full installation instructions, documentation and troubleshooting are available on the project website and GitHub repository.
