NREL/3TIER - Western Wind Resources Dataset

Each turbine icon represents a site consisting of ten 3 MW Vestas V90 turbines (for a total of 30 MW).

The 30,000+ sites were selected from over 1.2 million points based on pre-existing sites; transmission corridors and RE zones; load correlation and wind power density.

This data was modeled by 3TIER using the Weather Research & Forecasting (WRF) model to downscale the NCEP/NCAR reanalysis data.
