The report examines how digital technical standards—rules ensuring interoperability and scalability of ICTs—are created and governed. It highlights a fragmented landscape where developing countries face barriers such as limited resources, intellectual property restrictions, and geopolitical competition between the US, EU, and China. The document analyzes the role of the WTO, regional trade agreements (PTAs, DEAs, DTAs), and various standards development organizations (SDOs), recommending that developing countries prioritize open development processes and collaborative engagement to bridge the 'standardization gap'.

Smart grid investments in ASEAN could create between 243,000 and 649,000 jobs and attract industrial investment by providing reliable, low-carbon electricity. While member states have piloted battery storage and smart meters, scaling is hindered by investment gaps and fragmented standards. The document proposes a dual-track approach: ASEAN-level harmonisation of grid codes and standards to enable power trade, and national-level focus on financial viability and cost recovery. Such deployment would reduce reliance on polluting diesel backup generators in countries like the Philippines and Myanmar, improving urban air quality and public health.

ASEAN requires between $4 billion and $10.7 billion in smart grid investments to support its energy transition, depending on the chosen ambition level. The report outlines three investment pathways based on international benchmarks: a low-level distribution-focused approach ($4 billion), a medium-level renewable growth approach ($6.7 billion), and a high-level regional integration approach ($10.7 billion). While Singapore serves as a governance and technical model with its Grid 2.0 strategy and Digital Twin, most ASEAN nations will require a mix of blended finance, green bonds, and regulatory reforms to fund these upgrades, with the largest investment needs concentrated in Indonesia, the Philippines, and Vietnam.

The report highlights the critical role of grid reliability and 'smart grids' in sustaining ASEAN's economic growth and clean energy transition. While the region has seen improvements in outage duration and frequency, challenges remain regarding transmission capacity and the integration of solar and wind power. The document warns that failure to invest in digital intelligence and infrastructure could lead to nearly $2.3 billion in annual economic losses by 2040.

The report argues that smart grids are essential for ASEAN to integrate rapidly growing solar and wind capacity while supporting industrial growth. It estimates that an investment of $4 billion to $10.7 billion is needed to modernize power systems, which could potentially unlock $2.3 billion in annual economic value by 2040 and create between 243,000 and 649,000 jobs. The document highlights the need for regional cooperation to harmonize grid codes and mobilize green finance to overcome current fragmented standards and financing gaps.

Malaysia faces significant fiscal and energy security risks due to its heavy reliance on oil and gas exports, particularly LNG shipments to Japan, South Korea, and China. The document highlights a growing crude oil trade deficit and the threat of stranded assets as global demand shifts. To mitigate these risks, the report recommends diversifying into green manufacturing, hydrogen, and carbon capture services, while establishing a Sustainable Energy Transition Fund and a Just Transition Commission to support displaced workers in resource-dependent regions like Sabah and Sarawak.

Thailand's draft revised power development plan (RPDP) targets a 51% renewable energy share by 2037, up from a previous target of 36%. Despite plans to phase out up to 8 GW of fossil fuel capacity by 2037, the RPDP still includes 6.3 GW of new gas capacity. The report warns that increasing reliance on imported liquefied natural gas (LNG)—which is projected to reach 60% of the gas mix by 2035—exposes Thailand to price volatility and geopolitical risks, as evidenced by a 141% surge in the import bill between 2021 and 2022. The document suggests that Thailand could be more aggressive in transitioning away from fossils to avoid economic vulnerability and stranded assets.

Thailand's economic strategy to become a regional hub for electric vehicles (EVs) and data centres requires a rapid transition to clean energy to attract foreign investment and meet international low-carbon standards. The energy sector, which accounted for 69% of total emissions in 2019, is central to Thailand's goal of reducing greenhouse gas emissions by 30-40% by 2030 and achieving carbon neutrality by 2050. Projections indicate that EVs could account for 20% of total electricity demand by 2037, while data centre demand is expected to grow at an 8% CAGR from 2025 to 2027, potentially adding 10 TWh by 2037. To support this, the Thai government has introduced a direct power purchase agreement (DPPA) pilot project specifically for data centres of at least 50 MW, allowing them to bypass the single-buyer system and purchase renewable energy directly.

The report proposes a cost-optimal energy pathway for Thailand through 2037, suggesting that increasing solar capacity by 89% and battery storage by 60% relative to the draft revised power development plan (RPDP) 2024 can save $1.8 billion in power generation costs. This pathway aims to meet rising electricity demand from data centres (projected 10 TWh increase) and electric vehicles (projected 3.3 GW peak load increase) while reducing natural gas imports by 1,815 billion cubic feet. The analysis finds that wind energy is not financially viable without a 10% annual CAPEX reduction, suggesting imported hydropower from Lao PDR as a more cost-effective alternative.

Since April 2025, the United States has imposed high tariffs on several ASEAN nations, leading these countries to prioritize negotiation and diversification over retaliation. While Vietnam and Thailand faced the highest tariffs (up to 46% and 36% respectively), most members are balancing individual bilateral talks with a coordinated regional response led by Malaysia as the 2025 ASEAN chair. Strategies include increasing U.S. imports of energy and aircraft, leveraging the Regional Comprehensive Economic Partnership (RCEP), and implementing domestic stimulus packages, such as Thailand's USD 15 billion fund, to protect local industries.

The report argues that ASEAN's data centre industry requires a more diverse range of corporate renewable procurement options and stronger national sustainability frameworks to ensure sustainable growth. It evaluates various mechanisms—such as Power Purchase Agreements (PPAs), green tariffs, and Renewable Energy Certificates (RECs)—noting that limited availability of these options, particularly in countries like Indonesia, hinders investment. The text emphasizes that national frameworks are essential for managing energy transition risks and improving data transparency, as international standards are not always tailored to regional needs.

The report examines the energy demands of data centres in ASEAN, particularly those driven by AI, and argues that a dual approach of increasing solar and wind power procurement and enhancing energy efficiency is essential. It highlights that current grid emission targets in key hubs are insufficient and suggests that at least 30% of electricity demand in five ASEAN data centre hubs could be met by wind and solar by 2030 without immediate battery storage. The document emphasizes the critical role of cooling systems in tropical climates and the potential for software optimisation to reduce energy consumption.

The report examines the surge in data centre development in Southeast Asia, highlighting how increasing electricity demand—particularly in Malaysia, Indonesia, and the Philippines—threatens climate targets due to reliance on fossil-fuel-dominated grids. It argues that without significant investment in solar and wind energy and improved energy efficiency, the digital boom will lead to a substantial rise in greenhouse gas emissions.

The report highlights that data centres in ASEAN could account for 2% to 30% of national power demand by 2030, risking a significant increase in emissions, particularly in Malaysia, Indonesia, and the Philippines. It argues that approximately 30% of this demand can be met by solar and wind via grids without battery storage. The document advocates for more accessible corporate Power Purchase Agreements (PPAs), national sustainability frameworks, and advanced cooling technologies to ensure the sector's growth does not derail regional decarbonisation targets.

The document analyzes the competitive landscape of green investment in Southeast Asia, highlighting China as the leading public investor in clean energy between 2013 and 2023. It details the specific technological strengths of investor nations—such as Japan's lead in geothermal and solar and China's dominance in wind and hydropower—while examining the strategic frameworks used, including China's Belt and Road Initiative and Japan's Asia Zero Emissions Community. The report also notes significant financing gaps in the region, where annual renewable investments of USD 8 billion fell far short of the USD 27 billion required to meet 2025 targets.

The report argues that the ASEAN Power Grid (APG) can unlock significant renewable energy potential and enhance energy security by connecting resource-rich countries with high-demand markets. It highlights specific planned solar and wind projects, the role of the ASEAN Interconnection Master Plan Study (AIMS), and the potential for 30 GW of additional renewable capacity to generate 109 TWh of electricity and create 182,000 jobs.

ASEAN electricity demand grew by approximately 50% between 2013 and 2023 and is projected to rise by up to 41% by 2030. While the IEA's Announced Pledges Scenario (APS) targets 100,000 km of transmission line expansion for Southeast Asia between 2021 and 2030, the combined plans of Indonesia, Viet Nam, Thailand, and the Philippines total 45,078 km, covering only about 45% of that target. The document argues that grid planning must shift from merely meeting peak demand to managing the intermittency of wind and solar power, which saw cost reductions of 55% and 85% respectively in the decade to 2020.

The report argues that ASEAN's transmission grid expansion must roughly double to align with IEA pathways, as current national plans for Indonesia, Viet Nam, the Philippines, and Thailand cover only about 45% of the required expansion. It highlights that 30 GW of solar and wind potential is located along planned interconnection routes in countries like Indonesia, Malaysia, Cambodia, and Brunei. To support this transition, the report proposes a six-pillar framework for future-ready grid planning—including smart modernisation, strategic expansion, and market reforms—and suggests learning from the integrated power systems of Europe and Southern Africa to move from bilateral to multilateral power trade.

The report outlines the necessity for ASEAN countries to shift from reactive grid expansion to proactive system transformation to support variable renewable energy. It proposes a six-pillar framework for future-ready grid planning—covering smart modernisation, strategic expansion, flexibility, regional integration, regulatory reform, and sustainable finance—and draws comparative lessons from the integrated power systems of Europe and Southern Africa to advocate for a more connected and resilient regional market.

The report examines the need for grid modernisation and policy alignment in ASEAN to support the transition to renewables. It highlights the current dominance of fossil fuels, the risk of curtailment seen in Vietnam, and the potential of clean flexibility options such as pumped hydro, battery energy storage systems (BESS), and demand-side management (DSM) to ensure grid stability and enable cross-border energy sharing.
