India's data centre installed capacity is set to surge five-fold to approximately 7.5 gigawatts (GW) by March 2030, drawing investments of over ₹3 lakh crore across four fiscal years, according to a report by Crisil Ratings released on Tuesday, 3 November 2026. The projected expansion positions India as one of the fastest-growing data centre markets globally, driven by a confluence of generative AI demand, enterprise digitalisation, and rising data consumption.

Key Growth Drivers

The primary catalyst behind the capacity build-out is generative artificial intelligence (GenAI)-led computing demand, which is pushing hyperscalers — large cloud infrastructure providers — to lock in long-term capacity contracts in India. Enterprise digitalisation across sectors and rapidly growing domestic data consumption are reinforcing this momentum. According to the Crisil report, nearly half of the upcoming capacity is already committed under long-term agreements, significantly limiting speculative development and reducing offtake risk.

India's Structural Cost Advantage

'India's structural cost advantages further strengthen its attractiveness as a data centre destination. Development costs are around one-fifth lower than in several competing Asia-Pacific markets owing to more competitive land, construction and labour costs,' said Anand Kulkarni, Director, Crisil Ratings. Combined with lower power tariffs, this translates into rentals that are 30–35 per cent lower than in peer markets. The ability to develop large, renewable-powered campuses also aligns with the sustainability goals of hyperscalers, reinforcing India's competitive positioning, Kulkarni added.

Where the Capacity Will Be Built

About three-fourths of the upcoming 6 GW of new capacity is expected to be concentrated in Visakhapatnam, Mumbai, and Hyderabad. By fiscal 2030, data centre capacity in these cities could equate to roughly 80 per cent, 60 per cent, and 20 per cent of their respective current peak power demand — a scale that underscores the criticality of timely grid connectivity and transmission infrastructure augmentation.

Revenue Quality and Execution Risk

'The quality of contracted revenues has also strengthened. Contract tenors have lengthened to 15–20 years from 10–12 years earlier, enhancing cash flow visibility. Furthermore, high migration costs and rising replacement capex should support customer retention, although a meaningful contract renewal track record is yet to be established,' said Nitin Bansal, Associate Director, Crisil Ratings. The Crisil report cautioned that despite strong revenue visibility, the pace of expansion and the credit quality of data centre developers will hinge on timely power connectivity, regulatory approvals, and disciplined project execution. This comes amid a broader infrastructure bottleneck challenge that has constrained past large-scale industrial build-outs in India.

What This Means for India's Digital Economy

The scale of investment — ₹3 lakh crore over four fiscals — rivals some of India's largest infrastructure programmes. Notably, the data centre sector has historically attracted less policy attention than manufacturing or renewables, making this surge a structural shift in how capital is flowing into India's digital backbone. With GenAI workloads growing exponentially and India's cloud penetration still rising, demand-side pressure on capacity is unlikely to ease before the decade ends. Timely execution remains the single largest variable determining whether these projections translate into operational capacity.
