Building a more connected and sustainable South-east Asia

The region's future growth hinges on enhanced energy connectivity, as economies expand and electricity demand rises. The Asean Centre for Energy projects that regional energy demand could double by 2050, surpassing that of the European Union. Meeting this growing demand requires balancing secure energy supplies, affordability, and reduced carbon emissions through collaborative efforts.

Greater energy connectivity is key to bolstering collective energy security, unlocking economic opportunities, and accelerating the shift to a lower-carbon future. The Asean Power Grid (APG) exemplifies this vision by connecting national power systems across borders, enabling areas with abundant renewable energy resources to supply clean electricity to those with demand.

This will create a more resilient and diversified regional energy market, reducing exposure to global energy price volatility and enhancing energy security for all.

Cross-border electricity trade offers significant investment potential, as evidenced by planned projects from Indonesia to Singapore attracting up to $20 billion in investments into Indonesia. Strengthening domestic grid infrastructure will create well-paying jobs in the renewable energy sector and foster regional interconnectivity, which is not a zero-sum game but a source of shared value.

Singapore is committed to this vision by supporting low-carbon electricity import projects from across the region, fostering broader regional collaboration, and providing technical and operational experience to develop the APG. Realizing this vision necessitates more than infrastructure; it requires trusted partnerships, supportive regulations, and sustained investment.

Collaboration beyond Asean, including Australia, China, the EU, Japan, South Korea, and the US, along with international agencies like the International Atomic Energy Agency, International Energy Agency, and International Renewable Energy Agency, is crucial for accelerating regional energy integration and clean energy deployment.

The APG transcends being merely an energy project; it is an investment in South-east Asia's long-term resilience and competitiveness, laying the groundwork for a more connected and sustainable regional energy system. Regional cooperation encompasses building physical infrastructure and strengthening institutions, capabilities, and shared expertise to prepare South-east Asia for future energy challenges.

For instance, as more nations explore nuclear energy, collaborative research, capability building, safety, and regulatory frameworks are essential. Singapore's civil nuclear cooperation with the US exemplifies building the technical expertise needed for advanced nuclear technologies and contributing to regional efforts.

Platforms like the upcoming Singapore International Energy Week 2026 will further sustain this spirit of collaboration, bringing together governments, industry, and international partners to exchange perspectives and deepen cooperation on the region's energy future. The decisions made today will shape South-east Asia's trajectory for decades, with a secure, affordable, and sustainable energy landscape better positioning the region to attract investment, secure supply chains, and sustain economic growth.

By fortifying regional partnerships, South-east Asia can showcase that regional cooperation is not only vital for its energy transition but also for fostering a more prosperous and interconnected future for generations to come.
