Thailand: electricity in context
Power plants in Thailand produced 188 TWh of electricity in 2025. That is about 0.6% of the world total, in the same league as Pakistan. Natural gas dominates the mix with 65.5%, followed by coal at 17.8% and bioenergy at 5.4%.
16.6% of the country’s power came from renewable sources: 119th of 158 countries (in the bottom quarter). That is 17 points below the world average of 33.8%. It is also below the average for Asia (27.3%). Generating one kWh emits about 546 g CO₂e here (world average: 458 g). The grid is more carbon-intensive than the world average. In the cleanest-grid ranking, Thailand is 111th of 158.
Since 2015, the fastest-growing source has been solar power: its output rose by 7.6 TWh, lifting its share by 4 percentage points. The biggest decline came from natural gas (−5.2 TWh). The net effect: renewables gained 8.8 percentage points of share since 2015. Total generation grew by 10.4 TWh over the same period. Carbon intensity dropped from 597 to 546 g/kWh, a 9% cut.
Coal supplies 17.8% of electricity. That is 1.6 percentage points less than in 2015. The peak was 27.5% in 1991.
Solar (5.3%) and wind (1.8%) now add up to 7.1% of generation; the global figure is 17.3%. Per person, that is 139 kWh of solar electricity a year, versus a global average of 338 kWh. Solar first passed 1% of the mix in 2014.
Generation per person is 2,628 kWh a year, 68% of the world average of 3,860 kWh. Thailand is a net importer of electricity, buying 36.9 TWh more than it sells, about 16% of its demand.

Renewables and carbon intensity
Thailand against the world and Asia averages.
Total energy: beyond electricity
Primary energy covers transport, heating and industry too. Renewables supply 7.4% of primary energy and fossil fuels 92.6% (2024). Per person, that is 19,825 kWh a year (world: 21,654).
Substitution method: non-fossil electricity is converted to the primary energy a fossil plant would have needed.
Domestic extraction of coal, gas and oil, in energy terms.
Power plants in Thailand
The 196 power plants recorded in Thailand add up to 39.7 GW of capacity, 73% of it Gas. The largest is Bang Pakong at 4,384 MW. The database was last updated in 2021, so newer wind and solar farms and rooftop PV are under-represented.
