The Energy Security Pivot: Why Southeast Asia is Eyeing Nuclear Power
For decades, Southeast Asia has relied on a delicate balance of imported fossil fuels and a growing portfolio of renewables. However, geopolitical volatility—specifically the ongoing tensions involving Iran—has exposed a critical vulnerability: the region’s heavy dependence on the Middle East for oil and gas.
The potential closure of the Strait of Hormuz, a maritime chokepoint that handles about a fifth of the global oil trade, has served as a catalyst for a strategic shift. Governments are no longer viewing energy transition solely through the lens of decarbonization; it has become a matter of national and economic security.
baseload electricity—the minimum level of constant power required to keep a grid functioning—which is significantly more stable than the intermittent output of wind and solar.
Beyond Renewables: The Quest for Reliable Baseload Power
While solar and wind energy have seen massive investment across ASEAN, they face a fundamental challenge: inconsistency. Weather-dependent energy sources cannot yet fully replace fossil fuels for heavy industry or the burgeoning data center market without massive, costly battery storage solutions.
Nuclear energy offers a high-density, low-carbon alternative with a relatively small land footprint. This makes it particularly attractive for land-constrained nations and energy-intensive sectors that require a continuous, uninterrupted power supply.
“Markets that rely on one source or two sources of energy for power generation are not immune to any sort of cataclysms or events when there is a power disruption.” Arkady Gevorkyan, Citibank commodity strategist
The Strategic Shift Toward Diversification
The current trend mirrors Europe’s response to the Russian invasion of Ukraine, where a sudden loss of gas imports forced a rapid diversification of energy sources. In Southeast Asia, the motivation is similar: reducing exposure to external shocks and price spikes that can destabilize entire economies.
According to Tan-Soo Jie-Sheng of the Lee Kuan Yew School of Public Policy, the geopolitical crisis hasn’t necessarily created modern motivations but has reinforced and accelerated
existing goals related to rising electricity demand and decarbonization.
Regional Roadmap: Who is Leading the Nuclear Push?
The transition from theoretical interest to institutional planning is already visible across several key ASEAN players. Each country is taking a different approach based on its specific economic and geographic needs.
- Vietnam: Taking one of the most aggressive steps, Vietnam has signed an agreement with Russia to develop a nuclear plant with a capacity of 2,400 megawatts, targeting operations as early as 2030.
- Indonesia: The government has explored collaborations with Japan to develop potential nuclear projects in West Kalimantan.
- Malaysia: Nuclear energy has been integrated into long-term planning via the 13th Malaysia Plan, with officials assessing its feasibility amid shifting global dynamics.
- Singapore: Given its extreme land constraints, Singapore is focusing on studying advanced nuclear technologies and strengthening international cooperation.
The High Hurdle: Cost, Safety, and Time
Despite the strategic allure, nuclear energy is not a “quick fix.” Experts warn that the timeline from policy adoption to actual power generation is measured in decades, not years.
High upfront capital costs remain a primary barrier. The establishment of rigorous regulatory frameworks, the development of a specialized skilled workforce, and the complex process of site selection present significant logistical challenges.
Public perception also plays a critical role. Yao Lixia noted that public concerns regarding safety continue to pose challenges to the deployment of nuclear infrastructure.
The “Coal Fallback” Dilemma
In the interim, some nations face a difficult trade-off. To ensure immediate energy security while nuclear plants are being planned, some are returning to coal. This creates a paradox where short-term security needs clash with long-term sustainability and climate goals.
As Dr. Victor Nian suggests, the future of the energy transition may not be solely focused on decarbonization, but rather a hybrid of energy security and economic security

Frequently Asked Questions
Why is nuclear energy preferred over solar or wind for baseload power?
Unlike solar and wind, which are intermittent and depend on weather conditions, nuclear power provides a constant, steady stream of electricity, making it more reliable for powering cities and heavy industry.
Which Southeast Asian country is closest to deploying nuclear power?
Vietnam is currently among the most advanced in its timeline, having signed an agreement for a 2,400-megawatt plant with a target operation date of 2030.
What are the main risks associated with nuclear energy in the region?
The primary risks include high initial construction costs, the necessitate for stringent safety regulations, the requirement for a highly skilled workforce, and potential public opposition.
How does the conflict in the Middle East affect energy in Asia?
Because Southeast Asia is heavily dependent on Middle Eastern oil and gas, disruptions in the Strait of Hormuz can lead to price spikes and supply shortages, driving the push for domestic, stable energy sources like nuclear.
