There are wind maps of Thailand to see where there is sufficient diurnal stability and wind speeds to provide consistent maximum electrical production. Those I reviewed showed bare minimum (less the turbine is just a hair dryer) in the northern Thailand regions targeted for many wind turbine farms (aside from Phuket that ranks among the windiest places in Thailand). "Bare minimum" means less than rated capacity. "Less" means inefficient electric production.1 But efficient electric production doesn't seem to be the criteria, maybe it's the generation of government funds that's the goal.
And perhaps in terms of dependable operation at rated capacity explains the current governments' plan to focus on solar energy production on the country's lakes backed by dams.
1"Attempts at producing wind resource maps of Thailand all faced the problem of shortage in wind speed data, especially offshore and at high elevations... Thailand has relatively low average wind speeds with most areas being of class 1-1.4 wind speed, or about 2.8–4 m/s measured at 10 m. This is because Thailand is near the equator which has generally low wind speed.[4] In general, Thailand's inland winds are sub-par, but there are areas with topography such as mountain ranges, canyons, and slopes that help increase wind speeds."
