India is preparing for one of its biggest digital infrastructure expansions. More than ₹3 lakh crore is expected to flow into data centres over the next four financial years, as artificial intelligence (AI), cloud computing and rising digital consumption reshape demand for computing capacity. Yet, behind this investment opportunity lies a less glamorous but far more fundamental requirement: electricity.
India's installed data centre capacity is expected to increase five-fold to approximately 7.5 gigawatts (GW) by March 2030, according to a CRISIL Ratings assessment released on November 3, 2026. The expansion will involve substantial capital investment, with developers seeking to build facilities capable of supporting increasingly demanding computing workloads.

The projections underline India's growing importance in the global digital infrastructure landscape. However, they also raise a critical question: can the country's power infrastructure, transmission networks and supporting resources keep pace with the ambitions of data centre developers?
The answer could determine how successfully India converts the growing demand for digital services and AI computing into a sustainable investment opportunity.
The AI effect is changing the economics of data centres
Data centres are the physical backbone of the digital economy. They house the servers, storage systems and networking equipment that enable businesses, governments and individuals to access online services, process information and store data.
Their importance is increasing as organisations move more operations to the cloud and adopt data-intensive technologies. The emergence of generative AI has added another dimension to this demand.
Unlike conventional computing applications, many AI workloads require substantial processing power. Training and running sophisticated AI models involves large numbers of specialised processors working together. This increases the need for high-performance computing infrastructure, reliable electricity and advanced cooling systems.
The demand is already reflected in India's expanding data centre market. Cushman & Wakefield's India Data Centre Market H1 2026 report estimated operational capacity at nearly 1.8 GW, with a development pipeline of approximately 3.9 GW. The research also identified cloud adoption, AI workloads and enterprise digitalisation as important growth drivers.
CRISIL's projected expansion to 7.5 GW by March 2030 points to the scale of the next investment cycle.
The opportunity extends beyond companies operating data centres. Construction, electrical equipment, power generation, transmission, cooling technologies, networking and engineering services could all benefit from the expansion.
However, the industry is particularly capital-intensive. Developers must invest heavily in land, buildings, electrical systems, servers and cooling infrastructure before facilities begin generating meaningful revenue.
India's cost advantage is attracting investment
India has several advantages in competing for a larger share of the global data centre market.
According to CRISIL Ratings, development costs are approximately one-fifth lower than in several competing Asia-Pacific markets. More competitive land, construction and labour costs contribute to this advantage.
The cost difference is also reflected in rentals, which CRISIL estimates are 30–35% lower than in peer markets.
For international cloud service providers and hyperscalers, these economics make India an attractive destination for expanding computing infrastructure.
Policy support is adding to the investment proposition. The Union Budget 2026–27 proposed a tax holiday until 2047 for eligible foreign companies providing cloud services to global customers using data centre services in India, subject to specified conditions. The measure is intended to provide greater long-term tax certainty and encourage investment in domestic digital infrastructure.
India's ability to develop large campuses powered by renewable energy could further strengthen its position, particularly as international technology companies face increasing pressure to address the environmental impact of their operations.
But competitive costs and tax incentives can attract investment only up to a point. Developers ultimately need dependable electricity, adequate transmission capacity and the ability to commission projects on schedule.
Three cities face a significant power challenge
This is where the scale of India's planned expansion becomes particularly important.
CRISIL estimates that approximately three-fourths of the upcoming data centre capacity of around 6 GW is expected to be developed in Visakhapatnam, Mumbai and Hyderabad.
The concentration of investment in these locations could place considerable demands on their electricity infrastructure.

| Reliable electricity supply and transmission infrastructure will be critical to India's data centre expansion |
By fiscal 2030, the projected data centre capacity in Visakhapatnam could equal approximately 80% of its current peak power demand. The corresponding ratios for Mumbai and Hyderabad are estimated at around 60% and 20%, respectively.
These comparisons highlight the scale of the proposed infrastructure additions. They do not represent the projected percentage increase in each city's electricity consumption, but they indicate why grid connectivity and transmission augmentation will be critical.
A data centre requires a continuous and dependable power supply. Interruptions can affect servers, networks and the digital services hosted within the facility. Developers therefore need reliable grid connections, backup arrangements and adequate electrical infrastructure.
The challenge extends beyond supplying electricity to individual projects. Transmission networks must be capable of delivering the additional power to locations where large data centre campuses are being established.
The government has also recognised the growing electricity requirements of the sector. A Ministry of Electronics and Information Technology statement in March 2026 cited a Ministry of Power estimate of 13.56 GW in data centre electricity demand by 2031–32. A subsequent parliamentary update in July reported an additional projected load of 26.3 GW from AI data centres by the same period. The figures reflect different stated scopes and estimates, rather than a directly comparable revision of the same measure.
The larger message, however, is clear: data centre growth is becoming an increasingly important consideration in electricity planning.
Long-term contracts offer reassurance, but not immunity
Despite the infrastructure challenges, the demand outlook provides developers with an important financial advantage.
CRISIL reports that nearly half of upcoming capacity is already committed under long-term contracts. More than 95% of capacity currently under construction has also been contracted.
Existing facilities are operating at approximately 90% utilisation, indicating strong demand for available capacity.
An important development is the lengthening of customer contracts. Contract tenures have increased to 15–20 years from 10–12 years earlier.
Such agreements provide developers with greater revenue visibility and help reduce the risk of investing in facilities without confirmed customers. They also make it easier to plan financing and assess the potential returns from large projects.
However, the growing dependence on hyperscalers presents another challenge.
CRISIL expects hyperscalers to account for 75–80% of industry capacity by fiscal 2030, compared with 60–65% in fiscal 2026.
These large technology companies are important customers because of their substantial and sustained computing requirements. But their growing influence could also strengthen their bargaining power.
As more capacity becomes available and developers compete for large contracts, pressure on rentals could affect project returns. Long-term agreements provide revenue visibility, but they do not automatically protect developers from future pricing pressures or changes in customer requirements.
There is also the question of contract renewals. CRISIL notes that a meaningful track record of renewals has yet to be established in the industry. While high migration costs and the capital expenditure involved in replacing infrastructure could encourage customer retention, this remains an aspect to watch as the market matures.
The financial burden comes before the returns
The industry's investment cycle also creates a financing challenge.
Data centre projects require substantial capital expenditure well before they generate operating cash flows. According to CRISIL, investments typically precede cash generation by 24–36 months.
This means developers must carry significant financial commitments during construction and commissioning.
Debt levels are therefore expected to remain elevated over the medium term. As projects become operational and utilisation increases, stronger cash flows should gradually improve their financial position.
However, delays in obtaining approvals, securing power connections or completing construction could extend the period before revenue begins flowing.
Cost overruns or slower-than-expected customer demand could further weaken project economics.
The distinction between contracted capacity and operational capacity is important here. A signed customer agreement provides confidence in future demand, but the developer must still complete the facility, secure the necessary infrastructure and commission it before the contracted capacity can generate revenue.
Sustainability will be another test
Power availability is not the only resource challenge confronting the industry.
Data centres also require cooling systems to manage the heat generated by densely packed servers and computing equipment. As AI workloads increase, developers will need to accommodate higher power density and more advanced cooling technologies.
Water availability, land use and the environmental impact of large facilities will also require attention.

The government has begun addressing these issues through its policy framework. NITI Aayog's Data Centre Evaluation Framework, released in October 2026, encourages states to assess proposed investments across five areas: power and energy, water and cooling, siting and environmental sustainability, economic and strategic value, and policy, governance and implementation.
The framework recommends evaluating grid readiness, renewable energy and storage-backed power, as well as water availability and the impact on existing public resources.
These considerations are important because the economic value of a data centre investment cannot be measured only by the capital committed by its developer. Its long-term viability also depends on whether the supporting infrastructure and natural resources can sustain its operations.
The real test begins now
India's data centre opportunity is substantial. Growing AI adoption, cloud computing, enterprise digitalisation and rising data consumption provide a strong foundation for further investment.
The country also has competitive development costs, an increasingly supportive policy environment and growing interest from international technology companies.
But the next phase of growth will demand more than investment announcements and construction plans.
Power connectivity, transmission infrastructure, timely approvals, financial discipline and technological upgrades will determine whether the proposed capacity additions can be delivered efficiently.
For developers, the challenge will be to build facilities that remain commercially viable and technologically relevant over the long term. For policymakers and state governments, it will be to ensure that infrastructure planning keeps pace with private investment without placing unsustainable pressure on electricity, water and other resources.
India may be entering a major data centre investment supercycle. Whether it can turn that opportunity into lasting digital infrastructure strength will depend, to a considerable extent, on something far removed from the world of algorithms and artificial intelligence: its ability to deliver reliable power.
