What happened
Southeast Asian nations revive nuclear power plans to meet surging AI data centre energy demand and bolster security amidst the Iran war. Five ASEAN members, Indonesia, Malaysia, Thailand, Vietnam, Philippines, pursue nuclear energy, with nearly half the region potentially having it by the 2030s. Malaysia targets 2031, Indonesia 2034 (two SMRs), Thailand 2037 (600 MW), and the Philippines 2032 for operational plants. A standard AI data centre consumes electricity of 100,000 households; Southeast Asia accounts for a quarter of global energy demand growth by 2035.
Why it matters
This shift impacts procurement teams, infrastructure architects, and investors in the region's digital economy. National governments prioritise stable, high-capacity nuclear power for AI data centres, which demand substantial, continuous electricity. Countries set aggressive timelines, targeting operational capacity within a decade. This creates a new constraint for data centre site selection and energy supply contracts, as fossil fuel reliance becomes volatile. Energy supply will differentiate regional data centre operations, impacting procurement and infrastructure planning.
