What is the story about?
India’s data centre story has entered a phase defined by scale, speed, and optimism. Construction costs remain significantly lower than global peers, demand from digitisation and AI is accelerating, and total capacity is expected to expand rapidly over the coming years.
On paper, the country appears well-positioned to emerge as a major global hub for digital infrastructure. Yet beneath this momentum lies a growing tension. While India can build data centres efficiently, the deeper question is whether it can power, connect, and sustain them at the same pace. The emerging constraint is no longer capital or intent - but infrastructure readiness.
A cost advantage that fuels expansion
India’s data centre buildout is supported by a clear structural advantage in costs. As per a recent CareEdge Ratings report, construction costs are estimated to be 30–40% lower than in markets such as the US and China, aided by relatively lower land prices and competitive electricity tariffs.
This cost efficiency, combined with rising digital adoption and the increasing deployment of AI workloads, has made India an attractive destination for hyperscalers and cloud providers. As a result, the country’s total data centre capacity has been expanding steadily, with strong projections for continued growth through the decade.
Industry estimates suggest that India’s capacity could grow from roughly 1.2 GW in 2025 to around 4 GW by 2030, reflecting a multi-fold expansion in a relatively short period.
In 2026, only India’s total data centre (DC) stock across major cities is projected to increase by ~30% Y-o-Y, supported by an estimated 500 MW of new supply addition, according to CBRE’s India Alternate Sectors Outlook 2026 report.
The same report highlighted that in 2025, the total DC capacity in the country reached the ~1,700 MW mark, driven by a record 440 MW of new supply addition— a significant 160% surge compared to 2024. At the same time, utilisation levels have remained high, indicating sustained demand absorption.
Even as per Cushman & Wakefield’s 'Asia Pacific Data Centre Construction Cost Guide,' data centre construction activity is expected to remain concentrated in the top five markets, including India, until 2030.
Rapid growth, but from a low base
Despite this expansion, India’s data centre density remains relatively low compared to global benchmarks. Capacity per million internet users in India stands at approximately 1.2 MW, compared to a global average of around 5 MW.
This gap highlights both the opportunity and the constraint. On one hand, it signals significant headroom for growth while on the other, it underscores the scale of infrastructure required to bridge this divide.
One other issue is geographical concentration. Major clusters in Mumbai, Chennai, Delhi-NCR, and Bengaluru account for the vast majority of operational capacity, with Mumbai alone holding a dominant share due to its subsea cable connectivity and network advantages.
The invisible ceiling: power transmission
As capacity scales, the most critical constraint emerging is not generation, but transmission and distribution of power.
Anshuman Magazine, Chairman & CEO for India, South-East Asia, Middle East & Africa at CBRE, said, “Access to reliable grid power is likely to remain the biggest constraint in the data centre story. As workloads shift to more intensive, AI-driven GPU deployments in the coming quarters, the existing power infrastructure may come under pressure.”
Data centres require uninterrupted, high-quality, redundant power supply. While India’s generation capacity has expanded, transmission infrastructure and last-mile delivery remain bottlenecks in several regions. Upgrading transmission networks typically takes multiple years, creating a lag between demand and infrastructure availability.
Industry estimates suggest that data centres could account for approximately 2.5% of India’s total electricity consumption by 2030. With AI-driven workloads increasing compute intensity, power demand is expected to rise further, adding pressure on existing grids.
Prateek Aggarwal, Programme Lead, CEEW, said, "Transmission constraints are binding data centre growth in already concentrated markets like Mumbai and Chennai.”
He suggested three measures to address the problem. First, states should establish real-time transmission capacity portals so investors can identify available grid headroom before committing to a site.
Second, India needs dedicated data centre parks with a pre-built electrical backbone, where substations lead demand rather than follow it.
Third, developers should adopt on-site storage as a bridging solution, enabling facilities to begin phased operations on partial grid connections and scale up as full infrastructure becomes available.
Faced with transmission limitations, operators are not waiting for long-term grid upgrades. Instead, they are increasingly adopting alternative strategies to secure a reliable power supply.
A key trend is the direct procurement of renewable energy through partnerships with solar and wind providers. Hybrid energy models combining renewables with storage solutions are also gaining traction, allowing data centres to reduce dependence on the grid while maintaining continuity of supply.
Magazine added, “With India planning to add more renewable power capacity, the scale is being met through strategic partnerships with renewable energy firms for an uninterrupted power supply necessary to handle these advanced workloads.”
This shift reflects a broader transition: power strategy is becoming a core component of data centre planning, rather than a downstream consideration.
Connectivity: A second layer of constraint
Beyond power, connectivity infrastructure is another critical factor shaping scalability. Low-latency, high-capacity fiber networks are essential for hyperscale and AI workloads.
Currently, nearly 90% of India’s data centre capacity remains concentrated in four primary markets—Mumbai, Chennai, Delhi-NCR, and Bengaluru. Mumbai’s dominance is particularly linked to its role as a hub for subsea cable landing stations.
However, as demand grows, operators are increasingly exploring expansion into tier-II cities such as Ahmedabad, Indore, and Visakhapatnam. While these locations offer advantages in land availability and costs, their fibre ecosystems are still developing.
C.S. Krishnadas, Chief Executive Officer, Umiya Buildcon Limited, said, “The push towards edge data centres in tier-II cities is a step in the right direction, but it must be complemented by continued investments in fiber densification and network modernisation.”
Over time, improvements in long-haul fiber networks and edge infrastructure are expected to support this geographic diversification, but the transition remains gradual.
Sustainability pressures add another layer of complexity
Data centres are resource-intensive facilities, particularly in terms of energy and water usage. Cooling systems often require significant water consumption, raising concerns in water-stressed regions.
As a result, sustainability considerations are increasingly influencing both site selection and design. Operators are adopting advanced cooling technologies, water recycling systems, and energy-efficient infrastructure to reduce environmental impact.
Krishnadas added, “Balancing growth with sustainability is no longer optional- it is becoming a core part of operational and regulatory frameworks, and will play a defining role in how the next phase of India’s data centre ecosystem evolves.”
In parallel, state-level policy approaches are evolving. Some regions are reassessing incentive structures for data centre investments due to environmental concerns and questions around direct employment generation. This reflects a broader balancing act between attracting investment and managing resource constraints.
Per-GW costs show component volatility
Over the past year, the cost of building data centre capacity in India has remained relatively stable at a structural level, but operators have experienced volatility in certain technology components when evaluated on a per-GW basis. Experts said that fluctuations in global memory pricing have directly impacted the cost of active infrastructure, including servers, storage platforms, and networking equipment, which account for a significant share of overall capital expenditure.
Though Vijay Sampath Kumar, Chief Business Officer, Refroid Technologies, said, “The cost of building data centre capacity in India has increased compared to a year earlier, primarily due to higher power infrastructure costs, land prices, and the need for AI-ready, high-density deployments.”
He added that advanced cooling technologies and higher rack densities are increasing upfront capital expenditure, but they also improve operational efficiency and long-term scalability. As AI workloads continue to grow, we expect infrastructure investments per MW to remain higher than traditional deployments.
As data centres become more compute-dense and AI-ready, experts believe that the share of active IT and networking equipment in total project cost is rising, making budgets more sensitive to component-level price movements. This has made procurement planning and cost forecasting more dynamic compared to a year earlier.
At the same time, improvements in domestic manufacturing and supply chain localisation are helping improve cost visibility and resilience. While civil construction, land, and basic electrical infrastructure costs have remained broadly predictable, per-GW establishment costs are now increasingly tied to technology configurations, hardware refresh cycles, and global component pricing trends.
Building is easy - sustaining is the challenge
India’s data centre boom is grounded in a strong economic foundation: low construction costs, rising digital demand, and increasing adoption of AI-driven technologies. These factors are driving rapid capacity expansion and attracting significant investment.
However, the pace of growth is now confronting structural constraints. Power transmission bottlenecks, uneven connectivity infrastructure, and sustainability pressures are emerging as the key challenges that will determine how far and how fast the ecosystem can scale.
The ceiling India faces is not about the ability to build data centres - but about the ability to power, connect, and sustain them reliably across regions.
