How wind power grew in Thailand
EGAT installed six pilot turbines at Laem Phromthep on Phuket in 1983, and they were connected to the grid in 1990. EGAT's two 1.25 MW turbines at Lam Takhong in Nakhon Ratchasima followed in 2009. Larger farms came with West Huay Bong 2 and 3 in the same province, which started in 2012 and 2013. Each has 45 turbines of 2.3 MW.
The two farms sell to EGAT on 25-year contracts, with an adder of 3.50 baht/kWh for ten years. Wind Energy Holding's Aeolus Power owns 60%, and RATCH and Chubu Electric 20% each. By July 2020, 32 wind projects with about 1,460 MW of selling capacity were running. In 2017 lawyers reported that the Supreme Administrative Court had upheld a ruling that a wind farm's lease on agricultural reform land in Chaiyaphum was unlawful. A 2022 scheme offered 1,500 MW of wind at a feed-in tariff of 3.1014 baht/kWh. In October 2023 a court suspended the wind selection after Wind Khon Kaen 2, an Energy Absolute subsidiary, argued it was not transparent.
Wind generated 3.41 TWh in 2025, 1.81% of Thailand's electricity, from about 1.54 GW. Most of the country has low winds, and a 2001 World Bank study found good to excellent wind on only 0.2% of the land. The draft power development plan of June 2024 adds 5,345 MW of new wind by 2037, within 34,851 MW of new renewables.
