Summary:
India’s data centre capacity has surpassed 1.5 gigawatts (GW) as of September 2025, with Mumbai accounting for 53 % of the total. In short: India is rapidly building large-scale data infrastructure, and Mumbai is emerging as the dominant hub.
India’s total data centre capacity climbed past the 1.5 GW mark this year, driven by surging demand for cloud services, AI workloads and digital infrastructure. According to a recent industry report, Mumbai leads the country’s data centre market, holding around 53 % of the operational capacity — a reflection of its strategic importance due to submarine cable landings and global internet-exchange links.
The concentration of capacity is notable: after Mumbai, Chennai contributes approximately 20 %, Delhi-NCR close to 10 % and Bengaluru about 7 %, with the four cities together accounting for nearly 90 % of the total installed data centre capacity in India.
This growth is underpinned by favorable factors including government data-localization norms, rising AI and cloud adoption, and cost-competitive infrastructure compared to international markets. India has also secured investment commitments of nearly US$94 billion since 2019 in its data centre sector.
The rapid build-out positions India to become a major global data-centre hub. However, key challenges such as power availability, land acquisition, and infrastructure scale remain as the ecosystem expands beyond the metros into tier-2 regions.
