Description
The Mumbai data centre market has entered its highest-growth phase to date. The city maintains its position as India’s dominant infrastructure hub, commanding the largest share of national data centre capacity. The wider Maharashtra market, including Navi Mumbai, Panvel, Taloja, and now increasingly Pune, is evolving into one of Asia-Pacific’s largest hyperscale corridors. The key questions that the data and commentary within this report are attempting to answer: What are some of the early signs of AI infrastructure deployments in 2025-2026? How is the Mumbai datacentre landscape going to shift in response to AI infrastructure? What are some of the key developments that continue to make Mumbai one of the most lucrative markets in South Asia?
Demand is being driven by three converging forces. The first is hyperscaler expansion at unprecedented scale, with AWS, Microsoft, Google, and Oracle all committing multi-year, multi-billion-dollar capacity programs across the Maharashtra corridor. The second is the emergence of AI-ready GPU infrastructure as a standalone demand category, reshaping design standards, cooling architectures, and power density rather than simply adding incremental load. The third is policy: the Union Budget 2026–27 introduced a landmark 20-year tax holiday for foreign entities providing cloud services via Indian data centres, while Maharashtra’s land, power, and green energy frameworks continue to sustain Mumbai’s competitive position relative to challenger markets such as Hyderabad, Chennai, and Bengaluru. Mumbai benefits from all three vectors simultaneously.
The Mumbai market was worth USD 848 million in 2025 and is projected to grow 45% y/y to USD 1.2 billion in 2026. Pune has remained a core cloud region to one major hyperscaler due to its proximity to Mumbai and the ability to serve broader India. The Pune market was valued at USD 84 million in 2025 and projected to grow 48% y/y to USD 124 million in 2026. The projected five-year CAGR (2026-2031) for Mumbai and Pune is 25% and 28% respectively.
Hyperscale cloud continues to be at the centre of all things related to data centres in Mumbai and Pune. The hyperscale-oriented portion of the market, currently 70% in Mumbai, is expected to account for 89% by 2031 as hyperscale self-build sites become operational. Hyperscale colocation is expected to grow 55% y/y in 2026 and is expected to be the primary driver of growth in the Mumbai and Pune markets. The five-year CAGR for hyperscale colocation for Mumbai and Pune combined is projected to be 30%.
Despite strong fundamentals, challenges persist, and execution capability is becoming the key differentiator as the gap between announced megawatts and operational capacity widens. The market increasingly rewards operators who can deliver at density and on schedule over those who can simply announce capacity. Land acquisition in key clusters like Navi Mumbai and Chandivali has become more competitive, and infrastructure constraints around power delivery timelines continue to delay deployment. The permitting environment is improving but remains fragmented across local jurisdictions.
A more structural constraint is now emerging around grid-sourced power allocation for the Mumbai market. MSEDCL has allocated approximately 6 GW of grid power capacity to data centres in the key cluster of Navi Mumbai. With Structure Research’s current tracking of committed and under-construc- tion capacity already approaching that threshold on a net MW basis, further large-scale grid-dependent expansion within the established Navi Mumbai clusters faces a ceiling that permitting reform alone cannot resolve. This dynamic is accelerating two responses already underway. First, new builds are migrating to outer zones such as Panvel, Taloja, and Rasayani, where separate substation infrastructure can be commissioned independently of the constrained inner-cluster grid. Second, operators are adopting captive renewable generation at scale, enabled by Maharashtra’s October 2025 framework allowing data centre parks to generate and distribute their own power, as a partial substitute for grid dependency.
Mumbai will remain the leading Indian hub for cloud, content, and enterprise workloads. Built-out capacity is expected to cross 1.2 GW by 2026, with the broader Maharashtra market providing options for overflow and phased expansion through 2031.
