Thailand's government is introducing new screening rules for data centre investments, set to take effect in Q4 2026, designed to balance energy security with attracting foreign capital. The framework will require operators to post deposits (4.5M baht/MW), demonstrate genuine operations within 5–7 years, and prioritize hyperscale facilities with high employment/tax contributions over crypto-mining and storage. Existing BoI-incentivized operators may be exempt, but new projects face stricter compliance. This is a critical policy signal for Thailand's tech infrastructure ambitions, though implementation clarity on retrospective application remains uncertain.
