Asia-Pacific Data Centers Must Fund Grid Upgrades to Secure Power, Report Warns
A Bain and Standard Chartered study finds an $18 billion annual grid investment shortfall by 2035 is pushing operators to absorb infrastructure costs as a condition of grid access.
Data center power demand across Southeast Asia is on track to quadruple from 2.6 gigawatts to 10.7 GW between 2025 and 2035, according to Wood Mackenzie analysis, a trajectory already straining grid systems and pushing operators into co-investment arrangements that utilities once handled alone.2
The 2026 Southeast Asia Green Economy Report, published jointly by Bain & Company and Standard Chartered, finds that data centers, electric vehicles, and green industrial parks will add more than 100 terawatt-hours of incremental demand across the region within three to four years. Meeting that growth will require investments exceeding $200 billion, with more than half expected to flow into data centers as operators seek faster connection timelines and aim to avoid delays linked to grid access.1,3
The dynamic is playing out most clearly in Johor, Malaysia, where the data center sector's rapid expansion has run into hard limits on grid delivery. Connection timelines and infrastructure approvals have become the binding constraint, not planning permissions or land costs.4
By 2035, Wood Mackenzie estimates data centers will account for 3 to 4 percent of Southeast Asia's peak power demand, up from roughly 1 percent in 2025. That shift requires grid investment at a scale that utilities across Vietnam, Thailand, Indonesia, and Malaysia have not historically planned for. The IEA has separately calculated that global grid investment would need to rise by roughly 50 percent from the current $400 billion annual level to keep pace with demand through 2030.2,5
Bain and Standard Chartered put the annual grid investment shortfall for Southeast Asia at $18 billion by 2035. The gap reflects a structural mismatch: the region's grid infrastructure was built around legacy load patterns, while data center demand is concentrated, high-voltage, and requires dedicated interconnection capacity that can take years to install.1
Only about 60 percent of the $540 billion in announced green investments across power and electric vehicle supply chains in Southeast Asia is considered likely to proceed under current conditions, the Bain report found. The remainder faces cancellation risk from regulatory uncertainty, permitting delays, and in many cases the same grid capacity constraints now pushing data centers to co-fund infrastructure development.1
Renewable energy projects in Vietnam, Thailand, and Indonesia have experienced cancellation rates of 50 to 60 percent over the past five years, the report noted. That record suggests the infrastructure gap cannot be closed quickly even where commercial intent exists. Data center operators are absorbing the same lesson, with Johor serving as the clearest regional example of what pipeline congestion looks like in practice.1,4
Southeast Asia's green economy is currently valued at $290 billion and is projected to reach $430 billion by 2030. Whether that growth materializes at the forecast pace depends heavily on whether grid development can be accelerated, or whether data center operators must absorb a growing share of capital expenditure that utilities have historically managed.1
The IEA's broader power demand outlook — 3.6 percent annual average growth from 2026 to 2030, driven by AI infrastructure, EVs, air conditioning, and industry — implies sustained strain on Asia-Pacific grids extending well beyond Southeast Asia's immediate pipeline. East Asia and Pacific hydropower capacity topped 590 GW in 2025, with the region's pumped storage fleet reaching 106 GW, but generation capacity alone cannot resolve transmission and last-mile connection bottlenecks.5,6
For data center developers, the risk is that grid support obligations become a de facto qualification requirement for securing power access across the region. Where that threshold is set — whether formalized through regulation or negotiated case by case — will determine the pace of AI infrastructure buildout across Asia Pacific through the end of the decade.2,1
