When Cushman&Wakefield's report fixed the figure of 26.5 GW on the map of the Asia Pacific data center, Johor's capacity under construction is expanding northward at a growth rate of 91%, and Bangkok is ranked in the fastest growing list at a growth rate of 148%. In the first half of 2026, the development and reserve of data centers in the Asia Pacific region will reach a historic high - not due to site selection bottlenecks, but because electricity is redefining the computing power landscape. Traditional hubs are no longer the only option, and emerging markets with sufficient electricity are becoming the new coordinates for capital.

Dual line expansion under construction and planned

Cushman&Wakefield's Report on the Update of Asia Pacific Data Centers in the First Half of 2026 shows that, driven by the accelerated investment of super large customers, cloud service providers and AI platforms, the total amount of data centers under construction and planning in the first half of the year reached 26.5 GW, an increase of 7.1 GW compared with the end of 2025. Among them, 4.8 gigawatts are under construction, 21.7 gigawatts are planned, and approximately 1.4 gigawatts of operational capacity has been delivered.

The vacancy rate of custody has decreased from 10.9% in the second half of 2025 to 10.3%, and the newly added supply is being continuously digested by the market. Andrew Green, head of data center business in Asia Pacific region of Cushman&Wakefield, pointed out that "AI and cloud investment have entered a fast and power constrained implementation phase, and the challenges are increasingly focused on ensuring the power infrastructure required for next-generation AI load. ”

Southeast Asia becomes the main force of under construction capacity

Southeast Asia accounts for about 50% of the under construction capacity in the Asia Pacific region, with Malaysia leading with about 1 gigawatt and Thailand following closely behind with 859 megawatts. Johor's under construction capacity increased by 91% to 602 megawatts, while Bangkok surged by 148% to 859 megawatts. The total capacity of Johor's operation and planning has exceeded 4 GW, ranking first in Cushman&Wakefield's market maturity index.

Other markets also performed strongly: Sydney's total development capacity reached 2.1 gigawatts, an increase of 65%; Mumbai has 1.7 gigawatts, an increase of 31%; Jakarta has 1.7 gigawatts, an increase of 56%. Keywords: data center, high-tech

Pritesh Swamy, head of research and consulting for Cushman&Wakefield's Asia Pacific data center, said that modular construction and advanced cooling technology are helping operators shorten deployment cycles. As electricity becomes a more scarce resource than the internet, the coordinate axis of Asia Pacific computing infrastructure is tilting towards emerging markets with abundant electricity.Editor/Cheng Liting
