Thailand is moving to tighten rules for data centres, including higher electricity tariffs, upfront grid-access guarantees and tougher investment screening, as an artificial intelligence (AI)-driven construction boom raises concerns over pressure on the country’s power system and water resources.
But the government is pairing those restrictions with measures to give data centres and other industries greater access to renewable electricity, in an attempt to remain competitive for foreign investment while preventing the costs of servicing power-hungry facilities from being passed on to households.
hailand’s Energy Regulatory Commission is reportedly preparing a screening framework expected to take effect around the fourth quarter, with proposed requirements covering electricity consumption, grid stability, water management and the economic contribution of new projects.
The National Energy Policy Council in July approved a separate electricity tariff for data centres intended to reflect the actual cost of supplying them, including imported liquefied natural gas and investments required to strengthen the electricity network. The Energy Ministry said the principle was to ensure large electricity users pay their own costs rather than shifting them onto other consumers.
Data centres are expected to pay around THB5 to 6 (US$0.15 to 0.18) per kilowatt(kWh)-hour under the new structure, compared with a planned rate of THB3 (US$.091) per kWh for the first 200 kWh a househld uses in each montlhy billing period.
The regulatory push comes amid a surge in digital infrastructure investment. Thailand’s Board of Investment said investment applications exceeded THB1.01 trillion (US$31.8 billion) in the first quarter of 2026, about 2.4 times the amount recorded a year earlier. Digital sector applications accounted for THB873.7 billion (US$26.35 billion) across 48 projects, mostly data centres and cloud services.
Global technology companies including Google, Amazon Web Services and Microsoft have announced major investments in Thailand, while TikTok owner ByteDance and other international operators have also been behind large digital sector applications. The government sees the industry as an important pillar of its effort to build a regional hub for cloud computing and artificial intelligence.
That growth, however, is creating a new challenge for Thailand’s electricity system.
Energy Minister Akanat Promphan said in July that future electricity demand associated with data centres and AI could reach as much as 30,000 megawatts (MW), underscoring the scale of capacity authorities may eventually have to accommodate.
The problem is not unique to Thailand. The International Energy Agency expects global data centre electricity consumption to roughly double to about 945 terawatt-hours by 2030, with demand growing about 15 per cent annually between 2024 and 2030. In Southeast Asia, data centre electricity demand is also expected to more than double by the end of the decade.
