New Delhi, Sep 19 (NationPress) Mumbai has solidified its status as India's data centre hub, contributing to 40 percent of the nation’s overall capacity and 44 percent of operational IT capacity, as per a recent report.
In the initial half of 2025, the city's capacity surged by 14.3 percent, surpassing the 4 GW mark, which includes 591 MW currently operational, 185 MW under construction, and an impressive 3.2 GW in the pipeline, according to findings from real estate services firm Knight Frank.
This remarkable growth is part of India’s data centre sector, which exceeded 10 GW in the latter half of 2024, supported by 1.4 GW operational and 400 MW under construction, the report indicated.
With a total of 97.6 MW uptake over the past six months, the city’s data centre vacancy stands at 5.4 percent, significantly lower than the national average of 12.3 percent. Notably, two-thirds of the under-construction space is already pre-leased by various companies.
Three operational sites in Mumbai can accommodate hyperscale deployments exceeding 2.5 MW, and one site even offers more than 10 MW available. As a result, the fragmented market of smaller 1 MW–2 MW facilities has attracted global companies and joint ventures to develop high-capacity campuses, including NTT’s 500 MW NAV2 project and Blackstone-Panchshil Realty’s 500 MW AI facility.
Hyderabad, the second-largest data centre market in India at 2.1 GW, is also gearing up for hyperscale expansion with over 500 MW planned through two major projects, according to the report.
“With over 3 GW of capacity in the pipeline and strong policy backing for green data centre parks, Mumbai is drawing consistent global investments,” stated Shishir Baijal, Chairman and Managing Director at Knight Frank India.
Its robust subsea cable infrastructure, scalable power systems, proximity to enterprise hubs, and progressive state policies position it as South Asia’s gateway for cloud, AI, and enterprise workloads, he added.
“Mumbai has undeniably established itself as the core of India’s digital infrastructure expansion. While other cities like Chennai, Hyderabad, and Bengaluru are gaining momentum, none can compare to Mumbai’s scale, speed, and capability to serve as South Asia’s gateway for cloud, AI, and enterprise workloads.
Point of View
It’s clear that Mumbai’s ascendance as the leading data centre hub in India is not merely a trend; it reflects a deeper investment in the nation’s digital future. As competition heats up among cities like Hyderabad and Bengaluru, Mumbai's unparalleled infrastructure and policy support shine through, allowing it to maintain its position at the forefront of technological advancement.
