India's data centre capacity set for 5x surge by 2030: Crisil

India’s data centre capacity is expected to grow five-fold by March 2030. Crisil Ratings projects installed capacity of around 7.5 gigawatts, or GW. This scale matters because it signals a major expansion of the country’s digital infrastructure and the facilities supporting cloud services, enterprise technology and artificial intelligence.

Five times the current capacity means the industry would multiply its existing power-handling capability by five. Since the projected total is about 7.5 GW, today’s capacity is approximately 1.5 GW. The increase would therefore add roughly 6 GW of capacity, although the article focuses on the projected total rather than stating the present figure directly.

The expansion will require more than construction. Timely power connections, regulatory approvals and effective project execution will be essential. Nearly three-fourths of about 6 GW of upcoming capacity is expected in Visakhapatnam, Mumbai and Hyderabad, increasing pressure on local grids and transmission systems.

A data centre is a specialised facility containing servers, storage, networking equipment and supporting systems. Businesses use these facilities to run digital services, store information and process workloads. The article discusses data centres as the physical foundation for cloud adoption, enterprise digitalisation and GenAI computing.

Capacity measured in gigawatts describes the maximum electrical power that a data centre or group of facilities can support. It covers the computing equipment and essential support systems, including cooling and power infrastructure. A larger GW figure generally indicates the ability to operate more computing equipment, though it does not directly measure stored data or internet traffic.

The article projects India’s installed data centre capacity at around 7.5 GW by March 2030. That figure shows the planned scale of the physical infrastructure. Its delivery depends on power connectivity, transmission upgrades, regulatory clearances and disciplined project execution, especially in the three cities expected to receive most new capacity.

Generative AI, cloud computing, enterprise digitalisation and rising data consumption all increase demand for computing infrastructure. GenAI applications require substantial processing, while cloud services allow organisations to use computing and storage remotely. As more business activity moves into digital systems, companies need dependable facilities to run applications, analyse information and serve users.

The mechanism is straightforward: more digital services create more workloads, and more workloads require additional servers, storage, networking and electricity. The article specifically identifies increasingly compute-intensive GenAI workloads and cloud adoption as major forces behind investment decisions. Enterprise digitalisation and rising data use add further pressure for capacity.

This demand is encouraging rapid construction in India. Crisil expects capacity to rise five-fold to around 7.5 GW by March 2030. Strong demand from global hyperscalers also reduces uncertainty for developers. Still, demand alone is not enough; power connections, approvals and execution must keep pace with the planned build-out.

Hyperscalers are large technology companies that operate extensive cloud and computing platforms. They need substantial, reliable data centre capacity for cloud services and compute-intensive workloads such as GenAI. The article identifies strong demand from global hyperscalers as an important support for India’s investment boom.

Their long-term contracts create a clearer revenue path for a new project. If a hyperscaler commits to capacity before construction is completed, the developer has an expected customer and contracted demand from the outset. This reduces offtake risk, meaning the risk that available capacity will not find users. It also limits speculative development.

Nearly half of India’s upcoming capacity is already committed under long-term contracts, according to Crisil Ratings. These upfront tie-ups provide revenue certainty and help de-risk projects. However, contracts do not remove execution challenges. Developers still need timely power connectivity, regulatory clearances and disciplined construction to deliver the promised capacity.

More than Rs 3 lakh crore is expected to flow into India’s data centre industry over the next four financial years. This investment reflects rising demand from cloud services, GenAI, enterprise digitalisation and greater data consumption. It would fund the infrastructure needed for the projected five-fold capacity increase.

India’s cost advantage is a central attraction. Crisil says development costs are around 20 per cent lower than in several competing Asia-Pacific markets. More competitive land, construction and labour costs help produce that difference. Lower power tariffs then help operators offer rental rates 30-35 per cent below those in peer markets, making Indian facilities more attractive to large customers.

Renewable-powered campuses add another advantage. They can support hyperscalers’ sustainability commitments while offering large sites for expansion. These benefits strengthen India’s position, but investment success still depends on power availability, approvals and the ability to execute projects on schedule.

Power connections, transmission upgrades and regulatory approvals are essential links in a data centre project. If any of them arrives late, a completed or nearly completed facility may not be able to begin operations. That can delay commissioning, increase financing and construction costs, and weaken the project’s ability to meet customer commitments.

The pressure is concentrated geographically. Nearly three-fourths of approximately 6 GW of upcoming capacity is expected in Visakhapatnam, Mumbai and Hyderabad. By fiscal 2030, planned capacity in these cities could equal around 80 per cent, 60 per cent and 20 per cent of their current peak electricity demand, respectively. Those comparisons show why local infrastructure matters.

Crisil identifies timely grid connectivity and transmission capacity augmentation as critical. Without them, the expansion could face commissioning delays and cost overruns. Regulatory clearances and disciplined execution are equally important if India is to convert strong demand and investment plans into operating facilities.

Data centres consume substantial electricity because they run many servers and networking systems for digital services. Those machines process, store and move information, while cooling and power-support equipment helps keep operations stable. The article does not detail each electrical load, but it identifies data centres as infrastructure whose expansion depends critically on timely power supply.

Generative AI increases demand because its workloads are increasingly compute-intensive. Creating or processing AI outputs requires more computing work than many ordinary digital tasks. As cloud adoption and GenAI use grow, hyperscalers need additional facilities and electrical capacity. Rising data consumption and enterprise digitalisation add further workloads.

This explains the planned five-fold expansion to around 7.5 GW by March 2030. It also explains the infrastructure risk. In Visakhapatnam, Mumbai and Hyderabad, upcoming capacity could become a significant share of current peak electricity demand, making grid connections and transmission upgrades essential.
