• Power demand from data centres, EVs and green industrial parks in Southeast Asia is forecast to grow by more than 100 TWh in the next three to four years.
• The sectors will require more than $200 billion in investment, with data centres expected to absorb more than half of that capital.
• Only around 60% of the $540 billion in announced green spending across power and EV value chains is currently on a credible path to deployment.

Southeast Asia’s next phase of growth is moving onto the power grid.

Demand from green industrial parks, data centres and electric vehicles is forecast to rise by more than 100 terawatt hours in the next three to four years, according to the 2026 Southeast Asia’s Green Economy Report by Bain & Company and Standard Chartered.

The scale of the increase puts a sharp focus on whether the region can turn green economy ambition into bankable infrastructure. It also raises a harder question for governments and investors: can power systems expand quickly enough to support industrial growth without locking in higher emissions?

The report estimates that these three sectors alone will require more than $200 billion in investment. Data centres are expected to account for more than half of that total, driven by cloud demand, artificial intelligence workloads and the region’s growing role as a digital infrastructure hub.

For executives, the message is clear. Energy access is becoming a competitiveness issue, not only a sustainability issue.

Data Centres Are Willing To Pay For Speed

Data centre operators are already showing how power constraints can reshape investment decisions.

According to the report, almost all operators are willing to pay a premium to avoid grid connection delays. That finding matters for governments competing to attract digital infrastructure, because capital will likely move toward markets that can offer speed, reliability and cleaner power.

However, the region’s grid systems are not yet keeping pace. Southeast Asia’s power demand growth is expected to exceed the speed of grid upgrades. The report points to an estimated $18 billion annual shortfall in grid investment by 2035.

That gap creates risks beyond infrastructure delays. It could slow renewable integration, raise costs for industrial users and weaken the region’s appeal to global companies with strict climate targets.

For C-suite leaders, the grid is now part of site selection, supply chain planning and long-term risk management.

Green Spending Still Faces Execution Risk

Southeast Asia’s green economy is currently valued at $290 billion and is on track to reach $430 billion by 2030. Yet the report warns that announced investment does not always translate into deployed capital.

Across the region’s power and EV value chains, around $540 billion in green spending has been announced between now and 2030. However, only about 60% is on a credible path to deployment under current market conditions.

The gap reflects a broader challenge. Investors are not only looking for demand. They need stable rules, credible counterparties, clear permitting systems and bankable offtake structures.

Renewable energy development shows the strain. In Vietnam, Thailand and Indonesia, around 50% to 60% of renewable energy projects have been cancelled in the last five years. The report links those cancellations to system constraints, including unclear power purchase agreement structures, permitting challenges and grid connection rules.

These barriers turn policy design into a core investment issue. Without clearer governance, more capital announcements may remain stuck on paper.

Security And Growth Are Reshaping The Green Economy

The report also points to a shift in the rules of the green economy. Globally, security and growth are taking priority over sustainability in some policy and investment decisions.

For Southeast Asia, that shift brings both risk and opportunity. The region needs more power to support industry, transport electrification and digital infrastructure. At the same time, it must manage energy security, affordability and climate commitments.

That balance will shape the next wave of capital allocation. Investors will watch whether governments can speed up grid upgrades, reform permitting and improve power purchase frameworks. Companies will also need to assess whether clean power access can support their growth plans.

The region’s green economy remains one of the most important growth stories in global ESG. But the next stage depends less on headline targets and more on delivery. Southeast Asia has demand, capital interest and industrial momentum. Now it needs power systems that can carry the load.
