AI Boom Drives Record Electricity Demand in Thailand

Thailand's electricity demand is forecast to grow by 5.3 percent in 2026, the fastest rate in nine years. The Energy Policy and Planning Office attributes this surge to increased industrial activity, specifically electronics production and data center investments fueled by the global artificial intelligence boom. Domestic energy consumption already rose 6 percent in the first half of the year, with the industrial sector accounting for over 40 percent of total use.

To manage the resulting strain on the national power system, the Government of Thailand has halted dozens of data center projects. This pause allows the government to develop new regulations governing the electricity and water consumption of these facilities.

This trend extends across the region. BMI Country Risk and Industry Research reports that AI and data center expansion are intensifying grid capacity constraints throughout Asia. The firm raised its long-term electricity consumption forecasts for Vietnam, Malaysia, and Thailand, predicting annual average growth of 5.6 percent, 3.3 percent, and 2.9 percent respectively over the next decade. BMI notes that regulators in Thailand, Malaysia, and Australia are tightening rules to limit grid-connected load growth to maintain stability, which may lead to a resurgence in thermal power as policymakers seek dispatchable capacity.
