Southeast Asia’s Nuclear Pivot: Powering the AI Boom
Bangkok, Thailand – A dramatic shift is underway in Southeast Asia as nations grapple with surging energy demands fueled by the rapid expansion of artificial intelligence (AI) data centers. Several countries are revisiting, and in some cases, actively pursuing, nuclear power – a resource previously sidelined despite long-held ambitions. This pivot is being accelerated by global energy market instability, notably the ongoing Iran war, which underscores the vulnerability of relying on traditional fossil fuel sources.
The Data Center Demand: A Regional Power Grab
The growth of data centers in Southeast Asia is nothing short of explosive. According to Ember, the region currently hosts over 2,000 data centers across Indonesia, Malaysia, Singapore, Thailand, Vietnam, and the Philippines, with hundreds more under construction and over 1,100 planned. A single AI data center can consume as much electricity as 100,000 households, according to the International Energy Agency (IEA).
Malaysia is particularly ambitious, aiming to become a regional AI computing hub and attracting significant investment from tech giants like Microsoft, Google, and Nvidia. The country revived its nuclear program in 2023, setting a target of bringing atomic energy online by 2031. This growth is driven by expanding industries beyond data centers, including semiconductors and mining, all requiring substantial energy resources.
Nuclear Renaissance: From Mothballed Plans to Concrete Action
Five ASEAN member states – Indonesia, Malaysia, Thailand, Vietnam, and the Philippines – are actively pursuing nuclear energy. Vietnam is building two nuclear plants with support from Russia’s Rosatom, designated as “nationally significant, strategic projects.” Indonesia has added nuclear to its national energy plan, aiming for two small modular reactors by 2034, with cooperation proposals received from Canada, and Russia.
The Philippines, which built a nuclear power plant in the 1970s that never operated, has launched a recent atomic energy regulatory authority and set a 2032 target, approving a roadmap for potential investors in February. Even nations previously hesitant are showing interest; Cambodia’s national strategy signals openness to nuclear, and Singapore is studying its atomic potential. Brunei has also indicated it is “carefully exploring” nuclear energy.
Global Trends and International Cooperation
Southeast Asia’s renewed interest in nuclear power mirrors a global trend. Nearly 40 nations are now working to triple installed nuclear energy capacity by 2050. The World Nuclear Association estimates Southeast Asia will account for nearly a quarter of the 157 gigawatts expected from “newcomer nuclear nations” by mid-century.
The U.S. Is actively supporting this shift, with Secretary of State Marco Rubio signing an agreement with Malaysia in 2025 to facilitate civil nuclear cooperation. President Trump also supports expanding U.S. Nuclear power to meet growing data center demands, ordering a quadrupling of capacity within 25 years.
Challenges and Concerns Remain
Despite the momentum, significant challenges remain. Concerns surrounding nuclear safety, waste disposal, and public acceptance persist, stemming from past incidents like Chernobyl and Fukushima. While Japan is restarting its nuclear plants after the Fukushima disaster, public resistance remains a factor.
Experts caution that while nuclear energy can offer a solution to energy security and emissions reduction, it’s not without risks. Bridget Woodman of Zero Carbon Analytics warns that nuclear can appear deceptively attractive compared to alternatives like renewable energy, and countries starting nuclear industries from scratch must carefully consider the possibility of accidents.
The Energy Mix: Balancing Nuclear with Renewables
Currently, fossil fuels generate 81% of Malaysia’s electricity, with solar and wind contributing only 2%. While nuclear power offers a reliable baseload energy source, a diversified energy mix is crucial. Dinita Setyawati of Ember emphasizes that Malaysia’s decarbonization is “urgent and critical,” but the nuclear option should be approached cautiously.
FAQ
Q: Why is Southeast Asia turning to nuclear power now?
