Across the globe countries are responding to the surge in data center development in different ways. Thailand, one of the largest economies in Southeast Asia and with an ambitious high-technology sector, has increasingly become a key destination for data center projects, beyond the capacity of the Thai planning system. Government interventions announced in September 2026 are designed to provide a regime capable of handling new projects without losing the wave of investment.

Thailand officially has 35 data centers in operation, with 49 more under construction and 117 projects awaiting approval. Government ministers admit that planning controls are so ineffective that many more are likely operating illegally or identified as other types of buildings. The total capacity operating in the country is estimated to be between 250 MW and 350 MW.
