Unlike the power sector of other major economies in Southeast Asia (Indonesia, Vietnam, Philippines) that rely heavily on coal for electricity generation, the Thai power sector is dominated by natural gas (54% of generation in 2021). This is mainly due to the availability of the resource and its exploration in the Gulf of Thailand, which has gradually increased since the 1980s. Coal (17%) and imports (16%) however also played an important role in the power supply in 2021. Other renewables, including wind, solar and biomass have increased in recent years and generated 10% of Thailand’s electricity in 2021.
The main share of power is used for the country’s large industry sector (45%), followed by households (29%) and services (22%).
