Invest $4 - 10.7 billion in smart grids to fully unlock clean power potential

The report outlines the investment requirements for smart grid deployment across the ASEAN region to support clean energy integration. It estimates that ASEAN needs between $4 billion and $10.7 billion in investments, depending on the chosen pathway, to improve reliability, reduce curtailment, and enable regional power trade.

• ASEAN requires smart grid investments ranging from $4 billion to $10.7 billion to ensure reliable clean energy delivery. This total is divided into three indicative investment pathways based on international benchmarks: a low-level distribution-focused pathway at $4 billion (approx. $6 per capita), a medium-level pathway to enable rapid renewable growth at $6.7 billion (approx. $10 per capita), and a high-level pathway for regional integration at $10.7 billion (approx. $16 per capita).
• The majority of the regional investment need is concentrated in Indonesia, the Philippines, and Vietnam, which collectively represent more than 50% of the total required funding.
• Several ASEAN nations have established specific policy frameworks for grid modernisation: Malaysia's National Energy Transition Roadmap focuses on smart meters and cybersecurity; Thailand's 20-year Smart Grid Master Plan targets renewable forecasting and demand response; the Philippines has a Smart Distribution Utility Roadmap and a forthcoming Smart & Green Grid Plan; Indonesia has deployed over 1.2 million smart meters; and Vietnam is developing a Smart Grid Roadmap to reduce curtailment.
• Singapore's Grid 2.0 strategy serves as a regional example of early action, utilizing a Grid Digital Twin for real-time simulation and predictive maintenance. The country's cumulative spending on digital grid programs, including the $30 million SGD Intelligent Energy System pilot and $55 million SGD in Grid 2.0 R&D, totals approximately $65 million USD.
• Financing for smart grids in the region requires a mix of strategies. While advanced economies use capital markets and green bonds, developing countries rely more on concessional and blended finance from multilateral development banks (MDBs). The report highlights India's Revamped Distribution Sector Scheme, which uses performance-linked grants to fund smart metering and grid modernisation.
