Thailand's energy regulator is drafting screening rules for data centre power connections, expected to take effect around the fourth quarter of 2026 (timing not yet fixed). Proposed measures include upfront deposits (reported at 4.5 million baht per MW), a new electricity tariff, and proof of operations within 5-7 years. Rules mainly target new operators without BoI incentives; whether existing operators are covered is undecided. Unless your business is in data-centre construction, power supply or related services, this has little direct effect on you. It may affect electricity-price planning longer term.
