India’s cautious foreign investment approach accelerates data-centre capacity growth amid water and energy challenges

India is attracting foreign capital into its data-centre sector through minority stakes and debt structures, fueling rapid capacity expansion amid emerging energy and water constraints, as global investors shift focus to emerging markets amidst regulatory hurdles in developed economies.

Foreign capital is moving into India’s data-centre market in a more cautious form than outright takeovers, with investors increasingly backing local operators through minority stakes, convertible instruments and other debt structures instead of full acquisitions. S&P Global Ratings says that approach lets private equity and infrastructure funds scale capacity more quickly while avoiding some of the regulatory and execution complexity attached to cross-border control deals. It describes India as being in a rapid “capacity-expansion phase”, with the project pipeline now close to three times current installed capacity. (newindianexpress.com)

That financing shift sits inside a much larger global reordering of where server capacity is being built. S&P’s 3 September report says emerging markets already account for 35% of worldwide data-centre capacity, with China making up more than 60% of that share, and says the development pipeline across those markets is almost twice the size of current operating capacity. The agency argues that resistance to new data-centre construction in developed economies is pushing operators to look elsewhere, but warns that growth will not be evenly spread: countries with dependable electricity, transparent permitting, access to renewable energy and sufficient capital are likely to win a disproportionate share of projects.

India has spent several years building the policy framework that helps explain why it is attracting that money. S&P’s earlier India analysis traces the demand story back to the Reserve Bank of India’s 2018 requirement to store financial data locally, followed by a draft national datacentre policy in 2020, recognition of datacentres as infrastructure in 2022 and the Digital Personal Data Protection Act in 2023. In 2024, the government launched the IndiaAI Mission with a $1.2 billion outlay for graphics processing units, adding a direct AI-computing push to the localisation and digital-economy drivers already in place.

Those measures are feeding into a market that is already large by regional standards and still expanding quickly. S&P says India’s IT load capacity stood at 1.4 GW in the second quarter of 2025 and is expected to double within two years, with another 1.4 GW under construction. Local and international technology companies have announced more than $32 billion of data-centre investment over the past two years, while more than 95% of the capacity increase expected over the next five years is projected to come from leased facilities rather than dedicated hyperscaler builds. That helps explain why structured finance is gaining ground: investors can fund domestic platforms without waiting for full ownership transactions to clear. (spglobal.com)

The strongest clusters remain concentrated in a handful of states, and state policy is a material part of the investment case. Maharashtra, Telangana and Karnataka account for about 70% of India’s operating data-centre capacity, according to S&P. The report says incentives range from land and building-cost subsidies to single-window clearances and electricity-duty waivers. In Maharashtra, datacentres are treated as industrial rather than commercial consumers, allowing them to pay about 40% less in retail power tariffs. Karnataka offers lower industrial tariffs and a cash incentive where renewable energy provides at least 30% of consumption. S&P also points to Gujarat’s framework as an example of how infrastructure status and planning incentives can accelerate projects, while stressing that policy still varies sharply by state.

The constraint is that energy supply may become the decisive bottleneck even if capital remains available. S&P estimates India’s data-centre electricity demand was about 13 TWh at the end of 2024 and could rise almost fivefold to 57 TWh by 2030, taking the sector’s share of national power demand from 0.8% to about 2.6%. It expects India to become the second-largest market for data-centre electricity demand in Asia-Pacific within two years, ahead of Japan and Australia. To support that build-out, the country may need an additional 15 GW to 30 GW of renewable capacity over the next five years, yet S&P notes that grid expansion typically takes two to three times as long as renewable generation projects.

Water is the other major vulnerability. S&P says Mumbai, Bengaluru and Chennai, where many existing and planned facilities are concentrated, are already under water stress. Citing Uptime Institute data, it says a 1 MW load can require roughly 25.5 million litres of water a year for cooling. In the syndicated reporting on the new analysis, the agency rates India’s water resilience as “low” because of groundwater depletion in key urban clusters. The broader report also warns that communities may push back if data-centre construction is seen to raise electricity prices, weaken grid reliability or limit local access to land and water. That raises the likelihood of heavier use of water-efficient cooling systems and, in some markets, more reliance on independent power sources. (spglobal.com)

For now, S&P’s view is that India remains one of the more compelling growth stories in the emerging-market universe, with expected expansion of 2.7 times against 1.9 times for Brazil. But the report’s central message is that money alone will not determine the outcome. India’s ability to turn today’s surge of minority-capital and debt-backed investment into lasting hub status will depend on whether states can keep approvals predictable, grids expandable and water use manageable as AI-driven demand intensifies.
