India's installed data centre capacity reached about 1.9 GW in FY26, more than three times the level of FY19. By 2030, it is projected to reach 7 to 7.5 GW, and over the next decade it is expected to grow roughly tenfold. Investments of more than USD 120 billion have been committed by hyperscalers, global operators, and Indian players. At the same time, India's nuclear sector is changing fast, with new rules, private companies entering, and foreign vendors in talks. The two stories meet at one point: electricity. This article looks at that meeting point.
How Much Power the Boom Will Need
The growth in data centres has sped up. Capacity rose from about 778 MW in FY23 to about 1,900 MW in FY26, and more than 500 MW was added in the last year alone. The development pipeline is expected to add about 4.5 GW over the next five years, which is already two to three times existing supply.
The type of demand is changing too. AI and high-performance computing workloads are five to ten times more power-intensive than traditional cloud use. AI is expected to account for about 55 percent of data centre capacity by FY30 and about 65 percent by FY35. AI workloads alone are expected to need 400 to 600 MW of extra capacity by 2027, and data localisation rules are expected to add another 1,800 to 2,000 MW of demand in the same period.
What These Buyers Need From Power
Data centres running AI workloads need high power density and resilient power systems. They run around the clock, and their location decisions follow power access. About 90 percent of India's capacity sits in Bengaluru, Chennai, Delhi NCR, and Mumbai, while new projects are moving to Tier II locations partly because of land availability and improving power access.
Operators also want cleaner power. They are signing renewable power purchase agreements, installing solar and wind on site, and using hybrid renewable supply. Data centre operators have announced more than 3 GW of renewable PPAs, about 15 percent of the total. India has passed 500 GW of installed capacity, with about half from renewable sources. Closing the sustainability gap will still take sustained capital and closer work with utilities on grid upgrades and long-term clean energy access.
Where Nuclear Fits
The data centre sector's own material does not discuss nuclear power. The connection is a business reading, and it rests on what each side says about itself.
A data centre operator wants power that is steady, high in volume, and low in carbon. Nuclear power is round-the-clock, low-carbon electricity, and the government describes it as working alongside renewable energy while keeping the grid stable. A renewable PPA can cover part of an operator's needs. A steady nuclear source could cover the part that has to be there every hour of every day.
Size also matters. Large reactors of 700 to 1,600 MW supply national grids and industries, so data centre operators would reach them through grid supply and long-term contracts. Smaller reactors of up to 300 MW can serve industrial customers and replace retiring coal plants. India is developing the 220 MWe Bharat Small Modular Reactor and the 55 MWe SMR-55, with a goal of at least five indigenous SMRs by 2033. Large Indian conglomerates are planning integrated data centre campuses with their own power, land, and fibre, at gigawatt scale. A campus of that size is a natural place to ask what a dedicated source of firm power might look like.
The Timing Gap
Data centre demand is rising now. Nuclear capacity takes years to build. India's roadmap expects ongoing nuclear projects to reach 22 GW by 2031-32, and the SMR goal is set for 2033. Data centre capacity is projected to reach 7 to 7.5 GW by 2030, so nuclear power will not supply the first wave.
The more realistic role is the next wave. If capacity grows about tenfold over the decade, much of that growth lands after the early 2030s, which is when new nuclear capacity starts to arrive. The agreements, site choices, and partnerships that decide who supplies that later growth have to be started now, because nuclear projects have long lead times.
The Same Kinds of Players on Both Sides
Large Indian business groups appear in both stories. Conglomerates are among the big data centre investors, with USD 40 to 50 billion planned. In nuclear, Adani and Reliance are reported to be in talks with Rosatom, and private companies can now build, own, and operate nuclear plants under the SHANTI Act. The draft SHANTI Rules are open for public comment, and firms with a stake in both sectors have reason to take part.
What This Means for Businesses
Nuclear suppliers. Data centre operators are a new type of buyer. They think in uptime, power density, and speed to market. A supplier that can explain how a nuclear project meets those needs will be better understood than one that speaks only in reactor terms.
Data centre operators. The 2030s power supply is being arranged now. Talking early with nuclear developers and utilities about long-term clean power costs little and keeps options open.
Financiers. A long-term agreement with a data centre operator can give a nuclear project a clear buyer, which helps financing. The size of the committed investment shows that the buyers have the means.
India's data centre boom and its nuclear expansion are both about electricity. The companies that connect them early will have the clearest view of where demand and supply are heading. The 8th edition of NBP's India Nuclear Business Platform (INBP) 2027, taking place on 8-9 June in Mumbai, offers the ideal place to explore these opportunities, connect with key industry stakeholders, and understand where India's nuclear energy market is heading.
