ASIA sits at the centre of the global energy system — accounting for roughly half of global energy consumption and emissions, with demand continuing to rise.
In Asean, this growth is structural. Industrial expansion, digital infrastructure, and rising living standards are driving sustained increases in electricity demand. But today, this growth is being tested.
Recent geopolitical tensions, including disruptions to key transit routes such as the Strait of Hormuz, have exposed the fragility of energy supply chains. For Southeast Asia, where economies remain dependent on imported fuels, this is not a distant shock. It is a direct stress test of energy security, affordability and resilience.
This has triggered a fundamental shift — from a singular focus on decarbonisation to a more balanced, multi-dimensional approach which has clear practical implications for stakeholders across the sector. Investors are now evaluating projects not only on their carbon reduction potential, but on their contribution to grid stability, affordability and supply security. Utilities are prioritising more flexible and diversified portfolios, while policymakers are designing frameworks that support long-term system resilience.
The energy transition is no longer defined by decarbonisation alone. It is increasingly judged by its ability to deliver reliable, affordable energy in a volatile world.
An inflection point for the energy transition
Periods of disruption often accelerate structural change. What we are seeing today is an inflection point where resilience, flexibility and integration are becoming central to how energy systems are designed.
Global energy demand is expected to grow by approximately 15% over the next 15 years, with Asia as the primary driver. Meeting this demand requires more than adding capacity. It requires rethinking how energy systems are built and operated.
The transition is now about optimisation at a system level — across generation, storage, grids and end-use.
This is where we see the greatest opportunity.
Advancing a more diversified energy system
This shift places greater emphasis on diversification.
Renewables such as solar and wind are now among the most cost-competitive sources of new power generation in Asia. At the same time, storage is becoming critical to managing intermittency and enabling round-the-clock supply.
Across Asia-Pacific, hybrid renewable energy projects that combine solar, wind and battery storage are scaling rapidly, reflecting growing demand for more stable and dispatchable clean energy supply. In markets such as India and Australia, large-scale integrated renewable projects are increasingly being developed to support industrial demand while strengthening grid reliability. Beyond electrons, molecules will also play a role.
Hydrogen and ammonia are emerging as important pathways for decarbonising hard-to-abate sectors and enabling future cross-border clean energy trade. Governments and industry players are advancing early-stage supply chains and long-term offtake arrangements, signalling growing momentum towards a global low-carbon fuels market.
At the same time, EV adoption continues to grow across Southeast Asia, supported by expanding charging infrastructure and stronger policy support. This reflects the broader convergence of mobility, power and digital energy systems.
Individually, these are important developments. Together, they represent a shift toward integrated energy solutions.
Unlocking Asean’s renewable potential through integration
Asean is well positioned to accelerate the transition due to its diverse renewable resources.
The region has abundant renewable resources, a strong manufacturing base, and growing demand centres. But unlocking this potential depends on addressing one key constraint: infrastructure.
Solar remains the most widely available renewable resource in Southeast Asia, with high and consistent irradiation enabling large-scale deployment across markets such as Malaysia, Thailand and Indonesia.
Wind is also gaining traction. Vietnam has emerged as a leading market for both onshore and offshore wind, while countries such as the Philippines and Indonesia are exploring their potential. Offshore wind, in particular, is expected to play a larger role over time, with Asia projected to account for a significant share of global installed capacity by 2030.
Asean’s role is also evolving — from a demand centre to an active participant in the regional clean energy value chain. Asia’s established manufacturing base for solar, wind and batteries provide a strong foundation for cost-effective scaling. However, grid infrastructure remains a key constraint. Many projects are ready but delayed by limited transmission capacity and slow grid connections. Addressing this requires both domestic grid upgrades and stronger regional interconnection.
Cross-border interconnections such as the Vietnam–Malaysia–Singapore (VMS) initiative under the Asean Power Grid — demonstrate how linking national systems can move power from resource-rich areas to demand centres, unlocking large-scale renewable deployment while improving system flexibility.
For Malaysia, this creates a strategic opportunity to position itself as a critical clean energy transit hub, routing offshore wind from Vietnam through its national grid to Singapore.
From momentum to execution
Significant investment will be required to sustain the pace of the energy transition. Global energy investment is projected to rise by approximately 40% between 2025 and 2045 reflecting both the scale of demand growth and the complexity of transition pathways.
Capital is increasingly flowing towards a set of high-impact segments. Energy storage and hybrid renewable systems are scaling rapidly, particularly where round-the-clock supply is required for industrial users. Grid infrastructure and cross-border interconnections are emerging as critical enablers, supported by public funding, blended finance and regional development frameworks. Utility-scale solar and offshore wind continue to attract strong investment, underpinned by cost competitiveness and policy visibility. At the frontier, hydrogen and green ammonia projects are gaining traction, driven by industrial demand and export potential.
Together, these segments offer a balance of near-term returns and long-term strategic positioning — particularly in Asean, where demand growth and transition needs are converging.
To capitalise on these opportunities, investors can take actionable steps such as prioritising due diligence on grid and interconnection projects, where regulatory changes and infrastructure upgrades will likely unlock significant growth. Exploring blended finance models or partnerships with public sector entities can also improve project bankability and risk management, especially in emerging markets. By focusing attention on high-impact segments and actively engaging with policy developments, investors can position themselves to drive and benefit from Asean’s accelerating energy transition.
In Asia-Pacific, offshore energy investments alone are projected to average about US$150 billion annually over the next decade.
Momentum is building across key markets. India’s ambition to reach approximately 500 GW of renewable capacity by 2030 is accelerating both utility-scale and commercial and industrial deployment.
Australia continues to scale large solar and storage projects, while in Malaysia, policy mechanisms such as the Large-Scale Solar (LSS) programme and the Corporate Renewable Energy Supply Scheme (CRESS) are strengthening project bankability and enabling broader participation.
The alignment of policy, capital, and demand is steadily moving the transition from ambition to execution.
A long-term transition, moving at greater pace
Today’s pressures are reshaping the energy transition — accelerating the shift from ambition to delivery, and from isolated solutions to integrated systems.
For Asean, this presents a significant opportunity. While the transition remains long-term in nature, its pace is accelerating, driven by the need for systems that are not only lower in carbon, but also more resilient and adaptable.
These reinforces the value of acting early, especially in securing renewable capacity, strengthening grid infrastructure and investing in storage. The transition is evolving into a coordinated transformation, where diversification, integration and disciplined execution must advance together.
With the right foundations in place, diversification, integration and disciplined execution — the region can build an energy system that is not only lower in carbon, but also more resilient, competitive and secure. Asean is well positioned to turn today’s pressures into sustained progress — building an energy system that supports economic growth while enhancing resilience, competitiveness and security.
