Where Is Wind Power Generated in Thailand? Current Capacity and Locations by Province

Thailand’s wind power sector hit a wall. After a dramatic surge between 2016 and 2019, total installed capacity flatlined at roughly 1,545 MW for five straight years (TheWindPower.net, 2024). That’s enough to power roughly one million homes, yet it accounts for less than 2% of national electricity supply (ideas.energy, 2024). Yet how many people know where these turbines actually stand, who operates them, or why expansion stopped? This guide maps every major wind farm by province and capacity, explains the policy chokepoints, and lists the projects that could finally break the plateau.

TL;DR: Thailand operates roughly 1,545 MW of wind capacity across 34 projects, with 84% concentrated in Nakhon Ratchasima and Chaiyaphum (Mordor Intelligence, 2026). Growth stalled after 2019 when the 1,000 MW quota filled. Over 1,300 MW of new projects are in the pipeline, though most will not generate until 2027.

How Much Wind Power Does Thailand Have in 2025?

Thailand’s installed wind capacity reached approximately 1,545 MW by the end of 2024, with industry estimates nudging that figure to 1,600 MW in 2025 (Mordor Intelligence, 2026). That makes wind the fourth-largest renewable source behind bioenergy, hydro, and solar.

The growth curve tells a dramatic story. Capacity jumped from 223 MW in 2016 to 1,538 MW in 2019 — a nearly sevenfold increase in just three years (TheWindPower.net, 2024). Then it stopped. From 2020 through 2024, the total barely moved.

What does 1,545 MW actually mean in practice? The country generated roughly 3,812 GWh from wind in 2024, up 8.3% from the previous year (Statbase, 2026). That sounds healthy, but it still covers only about 1.7% of total electricity demand (ideas.energy, 2024). For context, solar contributes nearly 3% and bioenergy over 7%.

Thailand’s wind capacity surged from 223 MW in 2016 to 1,538 MW in 2019, then flatlined for five years at roughly 1,545 MW (TheWindPower.net, 2024). Despite zero net additions, generation rose 8.3% to 3,812 GWh in 2024 through better capacity factors, yet wind still supplies less than 2% of national demand (ideas.energy, 2024).

Where Are Thailand’s Wind Farms Located?

If you want to see Thai wind turbines, head northeast. The region around Nakhon Ratchasima and Chaiyaphum hosts 84% of the country’s total wind installations (Mordor Intelligence, 2026). The reason is simple: steady seasonal winds sweep across the Khorat Plateau.

Nakhon Ratchasima — known locally as Korat — is the undisputed hub. The province alone holds roughly 1,090 MW of operational capacity across nine major wind farms. Chaiyaphum ranks second with about 238 MW spread over four projects. Further south, Nakhon Si Thammarat contributes approximately 169 MW, while Phetchabun adds another 60 MW.

Why does the northeast dominate so completely? Southern provinces face different wind patterns and more complex terrain. Offshore potential is promising — studies estimate 7,000 MW possible — but no commercial offshore farms exist yet (T&D World, 2024).

The geographic concentration creates a hidden risk. A single grid disturbance or extreme weather event in Nakhon Ratchasima could disproportionately cripple national wind output. Thailand’s wind sector lacks the geographic diversity that solar enjoys, where panels span rooftops from Chiang Mai to Hat Yai.

Which Wind Farms Generate the Most Power?

Size matters in wind energy, and Thailand’s largest single facility is West Huay Bong 2 in Nakhon Ratchasima. It delivers 103.5 MW and is operated by K.R. Two Co., Ltd. (ThaiWEA, 2023).

Just behind it sits a cluster of five 90 MW projects: T4 KR One, T3 KRS Three, T2 Tropical, T1 Theparak, and NKS Krissana. Together, these six farms account for over 640 MW — roughly 42% of the entire country’s wind output. Most are concentrated in the Dan Khun Thot district, where flat terrain and reliable winds create ideal conditions.

State-owned EGAT operates the 26.5 MW Lam Takhong wind farm, one of the earliest projects. EGCO Group runs the small 7.5 MW Theppana site in Chaiyaphum. Private developers dominate the sector, though. Five conglomerates control more than 70% of both operational and planned capacity (Mordor Intelligence, 2026).

West Huay Bong 2 leads Thailand’s wind fleet at 103.5 MW, followed by five 90 MW projects clustered in Dan Khun Thot district, Nakhon Ratchasima (ThaiWEA, 2023). These six farms alone produce roughly 42% of national wind output, while five conglomerates control over 70% of all operational and planned capacity (Mordor Intelligence, 2026).

Why Has Wind Capacity Stalled Since 2019?

The numbers do not lie: Thailand added zero net wind capacity between 2022 and 2024 (TheWindPower.net, 2024). So what caused the freeze?

The root cause is a policy design that rewards early movers but chokes late entrants. The government set a wind quota of 1,000 MW for the 2022-2030 period under its feed-in tariff program (Watson Farley & Williams, 2024). Developers rushed to secure 25-year power purchase agreements at 3.1014 THB/kWh. Once the quota filled, new projects lost guaranteed offtake.

Does that mean wind is dead in Thailand? Hardly. The September 2024 auction earmarked 600 MW specifically for wind, drawing twelve bidders (Mordor Intelligence, 2026). Gunkul Engineering alone secured 319 MW. The problem is timing. Winning an auction and completing construction are different challenges.

What Wind Projects Are Coming Next?

Developers are betting on a second wave. At least 1,300 MW of new wind capacity sits in the active pipeline, though most will not reach commercial operation until 2027 or later (ACCIONA, 2025).

The biggest newcomer is ACCIONA Energía, which partnered with The Blue Circle to develop five projects totaling 436 MW. Sites span Ubon Ratchathani, Amnat Charoen, and Chaiyaphum, with commissioning expected between 2026 and 2030. GULF Energy has four projects totaling 286 MW slated for 2027. Wind Energy Holding, already a major player, secured roughly 299 MW across three new developments in Nakhon Ratchasima and Chaiyaphum.

When will these projects actually start spinning? Even with approvals and financing, wind farms take two to three years to build. Land agreements, environmental assessments, and grid connection queues add further delays. Do not expect a sudden capacity spike before 2028.

Over 1,300 MW of wind capacity is now in Thailand’s development pipeline, led by ACCIONA Energía’s 436 MW partnership with The Blue Circle and GULF Energy’s 286 MW portfolio (ACCIONA, 2025). However, most projects face two to three year construction timelines plus permitting delays, meaning significant capacity additions are unlikely before 2028.

What Does the Future of Wind Power Look Like in Thailand?

Thailand’s official targets are ambitious — perhaps too ambitious. The Power Development Plan 2024 calls for 5,345 MW of cumulative wind capacity by 2037 (Mordor Intelligence, 2026). The Alternative Energy Development Plan pushes that figure to 9,379 MW. Both targets require roughly tripling or sextupling current levels.

Is that realistic? Analysts forecast 2,370 MW by 2031 at a 6.8% compound annual growth rate (Mordor Intelligence, 2026). That trajectory would fall well short of either government plan.

Offshore wind could close the gap. Studies estimate Thailand’s Gulf of Thailand coastline holds 7,000 MW of technical potential (T&D World, 2024). The March 2025 opening of the Third Party Access framework added 2 GW of direct corporate PPA capacity, which may attract offshore investment. But cost remains a hurdle. Wind LCOE runs 2.7-6.0 THB/kWh in Thailand, while utility-scale solar often undercuts it (BloombergNEF, 2025).

For now, wind power remains a niche player in Thailand’s energy mix. It is concentrated, controlled by a handful of conglomerates, and dependent on policy auctions for growth. Without faster permitting and clearer auction schedules, those 2037 targets look distant.

Frequently Asked Questions

How much wind power does Thailand generate each year?

Thailand generated approximately 3,812 GWh from wind in 2024, representing about 1.7% of total electricity consumption (ideas.energy, 2024). That is enough to power roughly 800,000 average Thai households.

Where is the biggest wind farm in Thailand?

The largest operational wind farm is West Huay Bong 2 in Nakhon Ratchasima province, with 103.5 MW of capacity (ThaiWEA, 2023). Five other 90 MW projects in the same province follow closely behind.

Is wind power growing in Thailand?

Not currently. Net wind capacity has flatlined at roughly 1,545 MW since 2019 (TheWindPower.net, 2024). However, over 1,300 MW of new projects are in development, suggesting growth could resume by 2027 (ACCIONA, 2025).

What is Thailand’s wind power target for 2037?

The Power Development Plan 2024 targets 5,345 MW by 2037, while the Alternative Energy Development Plan sets a higher goal of 9,379 MW (Mordor Intelligence, 2026). Both require massive expansion beyond current capacity.

Can homeowners install wind turbines in Thailand?

Small-scale residential wind is rare. Thailand’s wind resource is concentrated in the northeast and select southern provinces, not urban areas where most people live. For home energy, rooftop solar is the practical choice.

Conclusion

Thailand’s wind power sector is a study in contrasts. It grew sevenfold in three years, then stopped completely. Over 1,500 MW now spin across the Khorat Plateau, yet the country gets less than 2% of its electricity from wind. The pipeline holds promise — ACCIONA, GULF, and local players are positioning for a second wave. Will Thailand hit those 2037 targets? Not without faster permitting, clearer auction schedules, and serious offshore development. For readers tracking the Kingdom’s energy transition, wind is worth watching. It just isn’t moving fast yet.
