India is entering a defining decade in digital infrastructure. Data centre capacity is expected to exceed 9 GW by 2030, nearly a 5x increase, with over $56 bn in fresh commitments in 2025. Net offtake grew more than 48% y-o-y in H1 2025, while vacancy remained below 5%.
That gap between demand and installed capacity reflects a market operating at high utilisation. As India enters its next phase, the focus will shift from capacity creation to execution at scale. Location strategy, infra innovation, sustainability and speed of delivery will shape long-term advantages.
Mumbai accounts for nearly half of India's operational data centre capacity and remains the preferred market for new builds, but peak city power stands at around 4.5 GW, while data centre demand is projected to exceed twice that. Meeting this will require continued grid augmentation and accelerated development of additional hubs.
Chennai, India's second hub, faces bottlenecks in extra-high-voltage power infra. Its share of the MW pipeline could moderate from 18% to 11-13% by 2028 as greenfield development shifts elsewhere. The next wave is emerging: Hyderabad, Vizag and Jamnagar are gaining traction. India's growth is likely to become more geographically distributed, with Pune, Noida, Bhubaneswar, Kolkata, Ahmedabad and Jaipur potentially emerging as future hubs. Site selection is now driven by ecosystem readiness as much as demand proximity.
Rapidly evolving computing demand is accelerating a new design paradigm. Traditional data centres were built 5-10 kW per rack. Workloads today start at 40 kW and are rising rapidly, with next-gen chips pushing densities toward 200-400 kW. Future-ready builds must integrate higher-density capabilities from the outset.
This shift has implications across three dimensions:
Cooling architecture is redefined. Air cooling reaches its physical limits beyond 30-40 kW per rack, making liquid cooling unavoidable. The global liquid-cooling market is projected to grow from $2.8 bn to over $21 bn by 2032.
Electrical systems are being re-architected, with higher densities driving the move toward high-voltage DC distribution and rack-level batteries replacing traditional UPS systems.
Physical design is changing from ground up. Floor loading is rising beyond 3,000 kg per sq m, ceiling heights are increasing to 7.5 m, and fibre density is scaling up to 12x. Future-ready data centres will need to be modular, flexible and designed for higher densities from day one.
As data centre footprint expands, managing power and water efficiently becomes critical. While the industry discusses greening its load, translating that ambition into reliable, round-the-clock RE supply is complex. Load ramp-up uncertainty makes early capital commitment to RE projects difficult, and variability in state-level regulations adds to execution challenges.
Water is a pressing constraint. Cooling-water consumption is projected to increase 11x by 2028, a serious concern given that many data centres sit in water-stressed cities. Power and water efficiency, measured through PUE and WUE, are largely determined at the design stage. Globally, hyperscalers target PUE of 1.2 and WUE of 0.3. In India, this is accelerating adoption of liquid cooling, closed-loop systems, and high-efficiency technologies such as magnetic-bearing, oil-free centrifugal chillers, which offer 20-25% higher efficiency than conventional systems.
Speed to commissioning is emerging as a key differentiator. Hyperscalers and enterprises are seeking delivery timelines of around 18 mths, while India's greenfield build cycle still ranges from 24-30 mths. Long-lead equipment is a critical bottleneck: gensets can take up to 1.5 yrs, and cooling and high-voltage electrical equipment face similarly extended timelines, compounded by a thin domestic manufacturing base.
Operators that demonstrate strong EPC, MEP and sourcing partnerships, combined with pre-ordering, volume blocking and early OEM engagement, will hold a structural advantage. Modular design approaches such as power skids, floor-level MEP decoupling and steel-over-RCC construction will be key to compressing timelines and delivering at speed.
India has the right ingredients: strong demand, strategic geography, construction costs 20-30% lower than the US and Britain, a talent base, and a supportive policy environment. Yet, critical gaps remain. The next phase will require more coordinated regulatory action, covering power allocation, domestic manufacturing of cooling and electrical equipment, India's position in global GPU supply chains, and clear water-use norms for data centre hubs.
The next decade will not be defined by who builds the most capacity, but by who builds faster, more efficiently, and with the right tech and sustainable design. Scale may get India noticed. Execution will determine whether it can sustain that advantage.
