ASEAN’s Energy Future: Beyond the Strait of Hormuz Crisis
The recent effective closure of the Strait of Hormuz, triggered by US and Israeli strikes on Iran, has exposed a critical vulnerability for Southeast Asian nations. While initial reactions focused on potential oil price spikes and supply chain disruptions, a more profound shift is needed. ASEAN’s reliance on imported fossil fuels, and the geopolitical forces that dictate access to them, is no longer an inevitable condition.
From Vulnerability to Sovereignty: A Regional Energy Reset
For too long, great power competition has been enabled by control over oil and gas supply chains. Recent events – from the US limiting Cuba’s oil access after a coup in Venezuela to the reshaping of LNG supply chains favoring more powerful states – demonstrate this reality. Southeast Asian economies, heavily dependent on imported energy, are particularly exposed, with energy access and costs dictated by foreign interests and vulnerable shipping routes.
However, ASEAN possesses the resources and technologies to break this dependency and secure its energy sovereignty. The region is exceptionally well-endowed with renewable energy potential: abundant solar irradiance, geothermal resources in Indonesia and the Philippines, hydropower along the Mekong Basin, and largely untapped offshore wind corridors.
The Economics of Decarbonization: A Turning Point
The narrative surrounding decarbonization is changing. It’s no longer solely a moral imperative requiring sacrifice. The dramatic decline in the cost of solar, wind, batteries, and related technologies means that the most secure and affordable energy system is increasingly a clean energy system. China’s experience exemplifies this. Recognizing the link between clean energy and energy security, China launched an ambitious clean energy investment strategy, achieving 84.4% energy self-sufficiency and decreasing its reliance on fossil fuels through electrification and rapid adoption of electric vehicles.
China’s investment has not only accelerated its own transition but has also driven down global costs, making renewables the most cost-effective option for fresh electricity demand.
Fragmented Systems, Amplified Costs
Currently, ASEAN’s energy systems remain fragmented. Individual countries plan their power systems in isolation, cross-border interconnection is limited, and industrial strategies are largely disconnected from energy planning. This fragmentation imposes significant economic and strategic costs, leading to higher system costs, redundant generation, and increased vulnerability to shocks like the Hormuz closure.
It also hinders the development of integrated regional value chains in critical minerals, manufacturing, and clean technology – essential for industrial competitiveness in the energy transition.
A Regional Architecture for Energy Independence
What ASEAN needs is a genuinely regional energy architecture that leverages the region’s diverse resources. Under Malaysia’s 2025 ASEAN chairmanship, Prime Minister Anwar Ibrahim championed the vision of an integrated, reliable, and sustainable regional energy system. This vision is now being formalized through the function of the ASEAN Centre for Energy (ACE).
For the first time, ACE is developing an optimized, least-cost, integrated, and decarbonized energy scenario for its forthcoming ASEAN Energy Outlook. This scenario centers on a connected grid, allowing surplus clean generation in one country to meet demand in another, improving reliability and reducing overall investment needs. Shared transmission infrastructure, financed collectively, can lower costs for all member states.
Building the Foundation for a Clean Energy Future
Plans for an integrated energy system aren’t new, but past efforts have lacked a cohesive approach. Success requires rigorous system-level modeling, robust economic analysis, modern industrial policies, a coherent investment plan, and appropriate governance structures that respect national sovereignty while enabling regional coordination. A financing architecture focused on affordability and regional benefit, rather than individual project risk, is also crucial.
ACE is uniquely positioned to provide the analytical and technical foundation for this regional planning, but it requires full support from member states to ensure its independence and focus on regional interests. Development partners should empower ACE by building its institutional capabilities, coordinating resources, and avoiding duplication of effort.
The Geopolitical Imperative
The current geopolitical landscape underscores the urgency of this transition. A region powered by its own renewable resources, connected by a shared grid, governed by shared institutions, and financed through a shared architecture, can set its own terms – for its industries, its trade relationships, and its economic future. Other regions are already demonstrating the strategic autonomy that comes with reducing fossil fuel dependency, and ASEAN has the potential to join them.
FAQ
Q: What is the biggest immediate impact of the Strait of Hormuz closure?
A: Increased oil and LNG prices, impacting energy-importing nations, particularly in Asia.
Q: What role does ACE play in ASEAN’s energy transition?
A: ACE is the mandated technical body responsible for guiding ASEAN’s energy future, developing regional energy scenarios, and providing technical expertise.
Q: What is needed to finance this regional energy transition?
A: A financing architecture focused on affordability and regional benefit, rather than individual project risk, is essential.
Q: Is a fully integrated ASEAN energy system realistic?
A: It requires strong political will, coordinated planning, and investment in cross-border infrastructure, but is achievable with the region’s resources and technological capabilities.
