Thailand is preparing a major screening framework for data-centre investment. Proposed measures include a 4.5 million baht electricity deposit per MW and a new power-user category 9 for data centres, with tariffs expected around 5-6 baht per unit (ministry estimate). The BOI is also shifting from project count to investment quality, with over 70% of promoted projects concentrated in the EEC. Google says the big-user tariff should not single out data centres and that large electricity users such as semiconductors should be treated the same way. For an SME, this is mainly background on future power pricing for large users. Watch for the final rules, since they may shape grid costs and industrial electricity rates over the coming years.
