In Southeast Asia, power demand for data centres is set to quadruple from 2.6 GW to 10.7 GW between 2025 and 2035, accounting for 3-4% of peak demand by 2035, up from 1% in 2025, according to Wood Mackenzie’s base-case scenario. What’s more, demand from data centres could surge even further, to 13.7 GW by 2035 under our high-demand scenario, should 75% of proposed data-centre projects be built rather than the 50% we assume in our base case.
Some 7-10%, or 48-70 TWh, of all power demand growth in Southeast Asia could stem from data centres over the next 10 years. That is roughly equivalent to Singapore’s total electricity demand in 2024.
The on-grid electricity cost for data centres in Southeast Asia is expected to quadruple between 2025 and 2035, too, as demand burgeons, rising from US$2.6 billion to US$10.2 billion.
On-grid costs for data centres vary significantly across the region. Singapore has the most expensive on-grid tariffs, at US$178/MWh in 2025. This compares with US$60/MWh in Indonesia, the lowest-cost market thanks to fuel and power-tariff subsidies.
