Wind Power Generation Technology hasWind Power Generation Technology hasbeen introduced in Thailand since 1983.been introduced in Thailand since 1983.This is mainly attributed to field test worksThis is mainly attributed to field test worksby Electricity Generating Authority of by Electricity Generating Authority of Thailand (EGAT). There are several Thailand (EGAT). There are several institutions that concerning in the fieldinstitutions that concerning in the fieldof assessment wind energy, developingof assessment wind energy, developingperformance testing and monitoring ofperformance testing and monitoring ofwind turbine for generating electricity.wind turbine for generating electricity.
