How it works
- Hourly 10 m and 100 m winds come from the ECMWF ERA5 reanalysis (about 30 km grid) through the free Open-Meteo historical weather API.
- Each hour is scaled from 100 m to hub height with that hour’s shear (power law), adjusted for air density at the site’s elevation, then run through a generic power curve for a modern ~3.6 MW, 140 m-rotor turbine. Losses cover wakes, availability, electrical and curtailment.
- Reanalysis data smooths terrain and often reads low at hub height. Treat this as a screening estimate—real projects use a year or more of on-site met tower or lidar data.
