Southeast Asia has never generated a single watt of nuclear power, but that's about to change as artificial intelligence (AI) data centers consume massive amounts of electricity. Five nations in the region are now actively pursuing nuclear energy to meet surging power demands, marking a dramatic reversal from decades of abandoned atomic ambitions. The shift reflects a critical tension: AI infrastructure is booming across Southeast Asia, but the region's energy grid cannot keep pace without radical new solutions. Why Are AI Data Centers Forcing Southeast Asia to Reconsider Nuclear Power? A single AI data center consumes as much electricity as 100,000 households, according to the International Energy Agency (IEA). Southeast Asia is home to more than 2,000 data centers spread across Indonesia, Malaysia, Singapore, Thailand, Vietnam, and the Philippines. Malaysia alone has over 500 operational data centers, with another 300 under construction and around 1,140 planned. This explosive growth is creating an energy crisis that traditional power sources cannot solve. The region will account for roughly one-quarter of global energy demand growth by 2035, driven largely by these AI infrastructure investments. Meanwhile, fossil fuels currently generate 81% of Malaysia's electricity, with solar and wind providing just 2%. As oil and gas reserves dwindle and climate pressures mount, nuclear energy has shifted from a taboo topic to a strategic necessity. Which Southeast Asian Countries Are Pursuing Nuclear Energy? Five of the 11 Association of Southeast Asian Nations (ASEAN) members are actively chasing nuclear power development. Here's where each nation stands: - Vietnam: Building two nuclear plants backed by Russian state corporation Rosatom, with a revised atomic energy law that took effect in January. Prime Minister Pham Minh Chinh called these "nationally significant, strategic projects". - Indonesia: Added nuclear to its new energy plan last year, aiming to build two small modular reactors by 2034. Canada and Russia have issued formal cooperation proposals. - Thailand: Set a target of adding 600 megawatts of nuclear generating capacity by 2037, with officials calling nuclear a "promising solution" for affordable, clean electricity. - Philippines: Built a nuclear power plant in the 1970s that was never activated. A new atomic energy regulatory authority launched last year, with a 2032 target and an approved roadmap for potential investors. - Malaysia: Revived its nuclear program last year with a 2031 target for bringing atomic energy online. The country aspires to become Southeast Asia's AI computing hub and has attracted investments from Microsoft, Google, and Nvidia. Even nations without firm plans are signaling interest. Cambodia's latest national strategy expressed openness to nuclear, Singapore outlined plans to study atomic potential, and Brunei told the International Atomic Energy Agency (IAEA) that it is "carefully exploring nuclear energy". Singapore How to Understand the Global Nuclear Expansion Driving Southeast Asia's Shift - Global Momentum: Nearly 40 nations, including the United States, Japan, South Korea, and China, have joined a push to triple installed nuclear energy capacity by 2050. Southeast Asia is expected to account for nearly one-quarter of the 157 gigawatts expected from "newcomer nuclear nations" by mid-century. - Current Capacity: More than 400 nuclear reactors in about 30 countries currently generate around 380 gigawatts of energy, making up between 4.5% to 10% of the world's total energy supply. - Future Projections: Global nuclear capacity will more than triple to about 1,446 gigawatts by 2050 if existing reactors continue operations and governments meet their stated targets. - US Leadership: President Donald Trump ordered the quadrupling of US nuclear power within the next 25 years, viewing nuclear as essential for meeting data center demands. The geopolitical context matters enormously. The escalating conflict in the Middle East has raised crude oil prices and underscored the vulnerability of Asia's energy supplies. This urgency is accelerating nuclear timelines across the region. "The ongoing conflict in the Middle East definitely demonstrates how volatile fossil fuel costs are and the instability of the supply. Nuclear is an alternative solution that can give us more self-reliance in terms of energy," stated Alvie Asuncion-Astronomo, a researcher at the Philippine Nuclear Research Institute. Alvie Asuncion-Astronomo, Philippine Nuclear Research Institute Vietnam and Russia advanced a nuclear power deal this week as the region's energy security concerns worsened. In South Asia, Bangladesh is racing to power up its new nuclear power plant, also backed by Russia, to address energy shortfalls. What Are the Risks and Concerns? Despite the momentum, significant concerns remain. Public resistance to nuclear power flared after the 1986 Chernobyl and 2011 Fukushima disasters. Safety, waste management, and supply chain vulnerabilities are legitimate worries for nations attempting to build a nuclear industry from scratch. Some experts caution that nuclear energy can look deceptively more enticing than less risky alternatives like renewable energy as the world falls further behind on climate goals. Bridget Woodman, a researcher with Zero Carbon Analytics, emphasized that Southeast Asian countries "considering starting a nuclear industry from scratch" need to carefully consider "the possibility of accidents". "We are not anticipating that nuclear electricity will be cheap at the onset," explained Asuncion-Astronomo. "But in the long term, it will improve the Philippines' energy reliability, security, independence and eventually costs." Alvie Asuncion-Astronomo, Philippine Nuclear Research Institute Yet even Japan, which idled all its nuclear plants after Fukushima, is now restarting them. This shift reflects a growing consensus that nuclear power is essential for meeting climate and energy goals simultaneously. What Does This Mean for the AI Infrastructure Race? Malaysia's nuclear ambitions are particularly telling. The country has positioned itself as Southeast Asia's AI computing hub and is competing aggressively for data center investments. Secretary of State Marco Rubio signed a civil nuclear cooperation agreement with Malaysia last year, calling it "a signal to the world of how civil nuclear cooperation is something that is available". The convergence of AI infrastructure demand and nuclear energy development is reshaping geopolitics. Tech giants like Microsoft, Google, and Nvidia are actively investing in Southeast Asian data centers, creating a powerful incentive for governments to secure reliable, long-term power supplies. Nuclear energy offers exactly that: stable, carbon-free baseload power that can support decades of AI computing growth. There is now "more serious, new and growing momentum for the development of nuclear energy in Southeast Asia," according to King Lee of the World Nuclear Association. The question is no longer whether the region will pursue nuclear power, but how quickly it can build the regulatory frameworks, supply chains, and public trust needed to make it work. For AI-hungry tech companies and energy-starved nations, the answer cannot come soon enough.
