According to a report on wind resource assessment of Thailand done by the Department of Energy Development and Promotion (DEDP) in 2001, there are good wind areas with an annual average wind speed of 6.4 m/s or higher at 50 m height. These areas are influenced by the monsoons and are located along the eastern coastline of the southern part of the Gulf of Thailand and in the mountains of the west and southern regions of Thailand. The fair wind areas with an annual average wind speed of 4.4 m/s or higher are mainly located on the west side of the Gulf of Thailand.

At its present situation with limited potential and associated high investment costs, wind energy is unlikely to be a major potential source of energy for Thailand. So far, only 192 kW of electricity produced from windmills has been installed in Phuket Province in the South of Thailand. It is expected that by the year 2006 the development of wind energy for power generation can be achieved at an approximate capacity of 3-6 MW.
