Energy resilience in ASEAN+3 strained by climate and demand

While the region has increased resilience to energy shocks, the forces listed above pose new challenges to macroeconomic stability. Climate change is no longer just an environmental issue. It is increasingly affecting energy systems, including generation, fuel supply and power grids, with severe consequences for the entire economy.

In 2024, natural disasters will cause an estimated $320 billion in economic losses globally, with Asia-Pacific among the hardest hit. In Southeast Asia, floods and typhoons regularly disrupt food systems, supply chains and infrastructure, including power grids and transportation networks for much-needed fuel.

These disruptions can quickly spill over into the real economy. Damage to energy infrastructure can cause power outages and increase costs, while floods often push up food prices and disrupt logistics. Subsequent recovery increases budgetary costs, and business losses worsen their financial position and increase credit risks for banks and insurance firms.

Preventive measures are needed

This is why climate risks need more than just emergency response plans. It takes sustained investment in climate adaptation and increased financial preparedness. The United Nations Environment Program estimates that countries in East Asia and the Pacific need about $141 billion annually to finance climate adaptation – more than any other developing region. However, in many countries, budgetary expenditures related to natural disasters are still only realized in the aftermath of these disasters.

Meanwhile, advances in technology are reshaping global demand for electricity. The rapid expansion of AI and digital infrastructure (data centers) is leading to a significant increase in electricity consumption. According to the International Energy Agency, electricity demand in Southeast Asia grew by more than 7% in 2024 and is projected to double by 2050 (one of the highest growth rates in the world). The region is also emerging as an attractive destination for data center investment: Singapore, Malaysia and Indonesia have become major regional hubs for cloud services and AI infrastructure.

As digital infrastructure expands, electricity demand is expected to continue to rise. Power systems will have to increase capacity, but in line with climate targets. While renewable energy capacity is growing, if it cannot grow fast enough to meet increased demand, authorities will face the need to use more fossil fuels to ensure reliable power supply.

Finally, geopolitical controversies create an additional level of uncertainty. Conflicts and trade disputes threaten to disrupt global energy supply chains, alter investment decisions, and increase fuel price volatility. These risks particularly affect ASEAN+3 countries, many of which are highly dependent on imported fuels, including liquefied natural gas.

When global energy prices rise sharply or become more volatile, there are usually spillover effects in the form of higher inflation, fiscal pressures, and external imbalances. Taken together, these recent developments increase the strain on the ASEAN+3 countries’ energy systems, underscoring the importance of improving energy resilience to ensure macroeconomic stability in the region.

Increase energy investment

What can be done? First, we need to invest more in climate-resilient infrastructure, which will help reduce the vulnerability of energy systems to natural disasters and limit economic disruptions in the event of shocks. Second, to meet growing electricity demand and climate goals, we need to expand generation capacity, strengthen transmission networks, and accelerate the transition to non-fossil energy sources. Regional initiatives such as theASEAN Power Gridare helping to support international trade in electricity, diversify energy sources, and increase the resilience of regional power grids.

Third, ASEAN+3 countries can build resilience through financial mechanisms. Ensuring preparedness through new financial and insurance instruments, as well as capital market solutions, will help governments deal with the fiscal costs of climate shocks and ensure investment in resilient infrastructure. The ASEAN+3 Finance Process, an important platform for regional financial cooperation, is leading discussions on a catastrophe risk financing initiative to improve fiscal risk management and expand the range of emergency financial instruments.

Our analysis and regional monitoring at the ASEAN+3 Macroeconomic Research Office (AMRO) show exactly how climate risks, energy market volatility and rising electricity demand can interact to create macroeconomic vulnerabilities. And our annual advisory reports now include tables of environmental assessments showing how climate risks can affect macroeconomic conditions and financial sustainability.

Improving energy resilience is not just an energy policy priority; it is a macroeconomic imperative. ASEAN+3 economies are caught at the intersection of climate risks, technological change and geopolitical uncertainty. By investing in sustainable and green energy systems, and strengthening regional cooperation, we can better meet these challenges while supporting stable, inclusive economic growth. The new wave of global turmoil only makes this challenge more urgent.
