ASEAN has just announced the next phase of the ASEAN Plan of Action for Energy Cooperation (APAEC) 2026-2030, and ASEAN Member States have signed the Enhanced MoU for the ASEAN Power Grid (APG). Adding to that, the Asian Development Bank (ADB) and World Bank Group have launched a Financing Initiative for the APG – a strong signal that regional power connectivity is taking yet more steps from vision to action.

It’s inspiring to see such momentum and purpose around the APG – an idea that is absolutely crucial not only for the energy transition in Southeast Asia but also beyond the energy sector, as a driver of deeper cooperation and resilience among ASEAN nations. When we connect grids, we also connect economies, strengthen energy security, and grow together as a bloc.

The scale of investment needed is immense – the ADB estimates at least USD 100 billion will be required by 2045 for transmission infrastructure alone. This underscores the urgency to mobilise funds – and to do so smartly, efficiently, and inclusively.
But money alone won’t do the trick. Three more ingredients are essential:
1. Political will & national alignment
Momentum at ASEAN level is strong, but success will depend even more on national commitments. Governments, utilities, and regulators must truly want the APG – understanding the benefits of multilateral power trade and backing it with clear policy direction. Without that, regional ambitions might remain aspirations.
2. Regulatory & policy frameworks
Stable, transparent, and harmonised rules will unlock finance and reduce the cost of capital. This means aligned grid codes, clear guidance for multilateral power trade, and robust risk mitigation tools – the building blocks that give investors confidence and lower financing costs.
3. Capacity & institutional readiness
Technical infrastructure alone won’t deliver electrons unless matched by strong institutions. Regional bodies, utilities, and regulators all need the skills and systems to plan, finance, and operate crossborder interconnections. Investing in people is just as vital as investing in steel.
In short: the momentum is there, the financing initiative is there – but we need the political, regulatory, and institutional foundations.
As CASE, we stand ready to continue supporting the ASEAN Power Grid and our partners across the region — helping to turn this shared vision into practice and impact on the ground.
The pieces are falling into place, and what is needed now is sustained collaboration and commitment. CASE will continue working with partners to bridge policy, finance, and technical expertise, ensuring the ASEAN Power Grid delivers real benefits to people and the planet. The energy transition is a regional journey. Let us keep the current flowing.
