India's installed data centre capacity is on track to more than quadruple from 1.5 gigawatts (GW) in 2025 to 6.5 GW by 2030, according to a report released on 22 July 2026 by Rubix Data Sciences. The sector has already logged explosive growth — up from just 375 megawatts (MW) in 2020 — and is now drawing comparisons to some of the world's fastest-expanding digital infrastructure markets.

Capacity Additions Accelerating

India added 387 MW of IT capacity in 2025, a 103 per cent year-on-year increase over the 191 MW added in 2024, according to the Rubix Data Sciences report. The pace of expansion signals a structural shift, not a cyclical spike. As of June 2025, India ranked seventh globally by number of data centres.

As of January 2026, 271 facilities spread across Mumbai, Hyderabad, Delhi NCR, Bengaluru, and Chennai collectively accounted for nearly 65 per cent of the country's total data centre capacity. This concentration in five metro hubs reflects both infrastructure maturity and the availability of skilled technical talent in these cities.

Investment Pipeline and Big Tech Commitments

The sector's investment pipeline currently stands at approximately $90 billion — roughly six times the $13–15 billion invested between 2020 and 2024. The surge is driven by large-scale commitments from Amazon Web Services, Microsoft, and Google, all of which have announced or expanded India-specific cloud regions in recent years.

The government has separately projected that AI-driven digital infrastructure, including data centres, could catalyse up to $200 billion in investment in the years ahead — a figure that underscores how central data infrastructure has become to India's broader economic strategy.

Power and Water Emerging as Critical Constraints

The rapid scale-up is not without friction. Water and power availability are emerging as critical bottlenecks, with data centre electricity demand projected to climb from around 1 GW today to 13.56 GW by 2031–32. That trajectory will place significant pressure on state grids and renewable energy targets.

States including Gujarat and Maharashtra have responded by introducing dedicated data centre policies aimed at extending growth beyond the traditional metro cluster. Notably, this push into Tier-2 corridors could help distribute grid load while opening new real estate and employment opportunities outside the five dominant hubs.

Data Centres Now a Major Real Estate Asset Class

The sector's financial footprint is expanding beyond technology into institutional investment. Data centres emerged as the second-largest recipient of institutional investments in India's real estate sector, accounting for 40 per cent of Q2 2026 real estate investments, according to a separate report cited by Rubix Data Sciences.

This growing share reflects rising investor appetite for digital infrastructure assets, underpinned by three demand drivers: rapid AI adoption, cloud expansion, and data localisation requirements under evolving Indian data protection regulations. The Rubix report described the data centre industry as 'a key indicator of India's digital and economic momentum,' with implications spanning technology, real estate, power, finance, policy, and sustainability.

With the 6.5 GW target still four years away, the sector's ability to resolve power and water constraints will largely determine whether India can sustain this trajectory and consolidate its position among the world's top data centre markets.
