Southeast Asia's Power Demand Is Set to Triple by 2030 — and Half Its Clean Projects Keep Getting Cancelled

Southeast Asia's Power Demand Is Set to Triple by 2030 — and Half Its Clean Projects Keep Getting Cancelled Data centres, EVs and green industry will need over $200bn of investment, but only 60% of announced green spending is likely to proceed, exposing a deliverability gap the region cannot yet close. Southeast Asia's power demand from green industrial parks, data centres and electric vehicles is expected to increase threefold to more than 100 terawatt-hours over the next three to four years, according to a report by Bain & Company and Standard Chartered.¹ Meeting that surge will require investments exceeding $200 billion, with more than half flowing into data centres as operators seek faster access to power and try to avoid grid-connection delays.² The demand side of this story is enormous and well documented. The supply side is where it breaks down. It matters because the region has a record of announcing clean-energy investment it does not build. Only around 60% of the $540 billion in announced green investments across power and EV supply chains is considered likely to proceed under current conditions, the report found.² More starkly, renewable energy projects in Vietnam, Thailand and Indonesia have faced setbacks severe enough that 50% to 60% have been cancelled over the past five years, owing to regulatory uncertainty, permitting problems and limited grid capacity.² A region planning to triple its power demand cannot afford to lose half its clean-supply pipeline, yet that is the recent track record. The demand drivers are concrete and accelerating, which makes the supply gap more dangerous. Data-centre power demand alone in Southeast Asia is set to quadruple from 2.6 GW to 10.7 GW between 2025 and 2035, reaching 3 to 4% of peak demand by 2035, up from about 1% in 2025.⁴ Layer on an EV boom across Thailand, Vietnam and Indonesia that is transforming the industrial landscape while the supporting power infrastructure remains critically underdeveloped, and the mismatch between load growth and grid readiness widens.⁵ The scale of the opportunity is real, which is why the execution problem is so costly. Southeast Asia's green economy is currently valued at $290 billion and is projected to expand to $430 billion by 2030, reflecting growing investment in clean energy and low-carbon industries.² That growth assumes the power gets built. If the grid and permitting bottlenecks that have killed half the region's renewable projects persist, the green-economy expansion runs into a hard physical ceiling, and the $200 billion of needed investment does not materialise at the pace the demand requires. The Middle East crisis has sharpened the exposure underneath all this. A surge in global fuel prices following the Strait of Hormuz disruption has revealed how heavily Southeast Asia still depends on imported fossil fuels for its energy security, with governments scrambling to stabilise supply and coal plants running at higher rates.⁶ Analysts frame that coal lean as temporary, a short-term response rather than a long-term direction.⁶ But temporary becomes permanent if the clean alternatives keep getting cancelled, and the import shock is exactly the kind of event that pushes a region toward whatever generation it can actually build. There is a demand-pull from the oil shock too, which cuts the other way. Rising crude prices have prompted a shift in consumer behaviour toward electric vehicles across Asia's oil-dependent economies, adding to the power demand the grid is already failing to meet.³ More EVs without more reliable generation simply moves the energy-security problem from the fuel pump to the wall socket. The signal to watch is the conversion rate of announced green investment into operating capacity, because that 60% figure is the whole story.² If permitting and grid reforms lift the share of projects that actually proceed, Southeast Asia can build toward the threefold demand increase and capture the $430 billion green-economy prize. If cancellations stay at 50 to 60%, the region triples its power demand while failing to triple its supply, and the gap is filled by the imported coal and fossil fuels the Hormuz crisis just showed to be a liability. The demand is not in doubt. Whether the power gets built is.^2,4
