India's digital engine is firing on all cylinders, but behind the screens of every stream, transaction, and AI query lies a rapidly growing physical world of data centres. A new spending boom is set to reshape this landscape.
An Investment Super-Cycle
India's data centre industry
is gearing up for a massive expansion, with a projected investment of over ₹3 lakh crore through March 2030. According to a recent report from Crisil Ratings, this investment will fuel a five-fold increase in the country's installed capacity, from around 1.5 GW in 2025 to approximately 7.5 GW by 2030. This surge isn't based on speculation; demand is already robust. Existing data centres are running at about 90% utilisation, and a remarkable 95% of the capacity currently under construction has already been pre-booked, primarily by global tech giants known as hyperscalers. This ensures revenue visibility for developers, with long-term contracts now extending to 15-20 years, a significant increase from the previous standard of 10-12 years.
The AI and Data Deluge
The primary force behind this unprecedented growth is the explosive demand for data and computing power. The rise of generative artificial intelligence (GenAI) is a major catalyst, as AI workloads require significantly more power and processing capability than traditional enterprise servers. An AI-focused server rack can consume 10 to 15 times more power than a conventional one. This is coupled with India's broader enterprise digitalisation, the rapid adoption of cloud computing, and surging consumer data consumption. With nearly 900 million internet users and billions of digital transactions each month, the need for robust, scalable digital infrastructure has never been greater. This digital activity, from streaming services to complex AI models, all runs on the physical hardware housed within these data centres.
Power Becomes the Deciding Factor
While land and approvals are important, securing a reliable, high-capacity power connection has become the single most critical factor for data centre development. The sheer energy demand of these new facilities is staggering. Projections show that around three-fourths of the upcoming 6 GW of capacity will be concentrated in Visakhapatnam, Mumbai, and Hyderabad. By 2030, the data centre load in these cities could equal a massive percentage of their current peak power demand—up to 80% in Visakhapatnam and 60% in Mumbai. This puts immense pressure on local grids, making timely transmission upgrades essential to avoid project delays. Consequently, data centre operators are now prioritising power strategy above all else, often investing in their own dedicated power infrastructure and long-term renewable energy agreements to ensure an uninterrupted supply.
Investment Hotspots and Economic Edge
Mumbai, with its extensive network of international submarine cables, remains India's largest data centre hub, accounting for over half of the country's current capacity. However, cities like Chennai, Hyderabad, and Noida are rapidly emerging as major destinations for investment. Hyderabad, in particular, is becoming a growth engine thanks to land availability and proactive state policies. India holds a significant competitive advantage due to its lower development and operational costs. According to Crisil, construction and labour costs are about 20% lower than in competing Asia-Pacific markets, and when combined with lower power tariffs, this results in rental rates that are 30–35% cheaper. This cost‐effectiveness, along with the ability to build large campuses powered by renewable energy, makes India highly attractive to global hyperscalers aiming to meet their sustainability targets.
