Thailand's draft 2026 Power Development Plan proposes 9,000 MW of small modular reactors (SMRs) to meet its net-zero commitment and reduce reliance on fossil fuels. The first domestic SMR unit is expected online by 2037, with capacity up to 300 MW per unit. This represents a major strategic shift for Thailand's energy transition, with clean energy projected to comprise 56–98% of the energy mix by 2050—up from 20% today. SMRs will complement renewable scaling and serve energy-intensive sectors like data centers and advanced manufacturing.
