This research presents wind energy assessment in the central region of Thailand in order to response the national policy Power Development Plan (PDP2018) that helps to increase the proportion of electricity generation from wind energy. Wind speeds are represented in the wind atlas by using the global wind atlas methodology that developed by DTU Wind Energy and Vortex under the support by World Bank Group. Wind atlas at the level of above 100 m was validated using measured wind speed data obtained by 6 masts in the central region of Thailand. The Global Wind Atlas (GWA) methodology applied the wind climate of ERA5 in the period of 10 years (2008 – 2017) provided by European Center for Medium-Range Weather Forecasts (ECMWF)at resolution of 30 km forced with mesoscale WRF atmospheric modeling under 3 km resolution. Results from mesoscale were input for microscale wind flow WAsP modeling along with digital 30 m high-resolution topography. Results showed that the mean error of wind at 100 m obtained from GWA methodology was 16.31%. Based on wind atlas by GWA methodology, it was found that were potential areas with mean wind speed more than 6.0 m/s in the western, northeastern and southern of the study area. Wind atlas by GWA methodology could be used for met mast installation for further micro-siting in a wind power plant development.
