Thailand Wind Energy - Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026-2031)

The thailand wind energy market size is expected to grow from 1.60 gigawatt in 2025 to 1.71 gigawatt in 2026 and is forecast to reach 2.37 gigawatt by 2031 at 6.82% CAGR over 2026-2031. This report is Segmented by Location (Onshore and Offshore), Turbine Capacity (Less Than 3 MW, 3 To 6 MW, and Above 6 MW), and Application (Utility-Scale, Commercial and Industrial, and Community Projects). The Market Size and Forecasts are Provided in Terms of Installed Capacity (GW).

Thailand Wind Energy Market Trends and Insights

Government Renewable Capacity Targets to 2036

The Power Development Plan 2024 mandates 5.345 GW of cumulative wind additions by 2037, tripling the present fleet and positioning wind behind solar as the grid’s second-largest renewable source. Reducing dependence on imported liquefied natural gas underpins the policy, yet average site wind speeds of 2.8-4.0 m/s at 10 m hub heights demand tall turbines, inflating capex. Maintaining the THB 3.10 tariff through 2030 shields returns, and the September 2024 auction drew 12 bidders chasing 600 MW, underscoring confidence despite sub-30% capacity factors. Streamlined environmental reviews now close within 12 months for ≤90 MW projects, helping developers halve pre-construction time. The International Energy Agency lifted Thailand’s renewable forecast by 26% in 2024, chiefly on stronger wind delivery signals.

Competitive FiT / Auction Schemes Attracting IPP Capital

A two-track incentive, feed-in tariffs for sub-10 MW plants and auctions for larger arrays, mobilized THB 80 billion in committed wind outlays since 2022. The 25-year tariff stands 40% above wholesale prices, enabling IPPs to secure low-cost multilateral debt; for instance, the Asian Development Bank syndicated USD 820 million to Gulf Energy in November 2024. Auction caps of 90 MW curb market dominance, yet joint ventures allow scale, as shown by Gulf’s 208 MW tie-up with Alpha Energy announced in September 2025. Non-firm dispatch clauses clip realized tariffs during solar midday peaks, trimming payouts by nearly 15 %. Ongoing litigation over bid scoring indicates investor sensitivity to transparent oversight.

Low Average On-Shore Wind Speed Zones

National mean winds of 2.8-4.0 m/s at 10 m classify most sites as Wind Class 1, forcing 100 m hub heights and lifting capex by nearly 18% versus Class 3 sites in Vietnam. Capacity factors averaged 28 % in 2024, roughly 1,400 full-load hours below the global norm; hence, the Thailand wind energy market relies on tariffs 30 % above peers to attain 10-11 % equity returns. Central and southern zones exhibit sub-5 m/s winds even at 80 m, explaining why 85 % of projects cluster in the northeast. Ember’s 2024 review noted wind’s LCOE still trails solar’s by at least 25 % under Thai conditions.

Other drivers and restraints analyzed in the detailed report include:

• Falling LCOE from Larger Turbines & Supply-Chain Scale
• Corporate REC Demand & Green-PPA Boom
• Rural Grid Bottlenecks & Curtailment Risk

Segment Analysis

Onshore assets represented the entire Thailand wind energy market size of 1.60 GW in 2025, and onshore additions are slated to grow 6.85% CAGR to 2031 under the 600 MW second-phase auction. Offshore resource studies show 5.5-6.0 m/s winds in 50-80 m waters, but breakeven tariffs exceed THB 5.00 /kWh, well above current policy support. Northeastern onshore sites lie near 115 kV lines, keeping grid-tie costs at THB 8 million /MW compared with THB 25 million /MW for subsea cables. Acciona Energía’s 436 MW commitment underscores sustained developer preference for land-based projects that clear USD 0.070 /kWh LCOE at 80 m hub heights.

Developers anticipate a 200 MW offshore pilot in 2027, yet commercial deployment will likely trail the forecast window because floating foundations add USD 1.2 million /MW. Consequently, onshore capacity should still control at least a 94.75% Thailand wind energy market share by 2031 while offshore remains a policy aspiration.
