Egat is investing 31 billion baht to upgrade the power transmission system in the Eastern Economic Corridor (EEC) to alleviate electricity supply bottlenecks for data centres. The Phan Thong substation will receive 1.5 billion baht for upgrades, increasing capacity from 600 MW to 1,150 MW.

Four data centres are under construction in Amata City Chon Buri, and 16 more are expected by 2030, demanding 3,600 MW. Thailand's electricity consumption peaked at over 33,000 MW last year with a supply capacity of 55,000 MW, providing over 30% reserve capacity.
