India’s Data Centre Boom Strains Power and Water Resources
India’s rapid data centre expansion, driven by global tech investments and sovereign AI demand, is colliding with environmental limits. While billions are being poured into infrastructure, experts warn of unassessed costs to electricity grids and water supplies, with state policies offering incentives but few conditions.

India is experiencing a surge in data centre development, driven by demand for local cloud infrastructure and sovereign AI. According to a PwC report, global data centres could attract $31.6 trillion in capital expenditure through 2050, with annual spending rising from $800 billion in 2026 to $1.1 trillion by 2030 and $1.8 trillion by 2050. The Asia-Pacific region is expected to draw $8.2 trillion in cumulative investment, with India and China contributing the largest incremental demand.
Technology companies have announced nearly $300 billion in Indian data centre investments over the past two years, and more than 5 GW of additional IT load is expected by 2030. BloombergNEF reports that Reliance Industries and the Adani Group have committed $210 billion combined, while Google, Amazon, and Microsoft have announced $84 billion collectively.
However, the rapid buildout is colliding with resource constraints. S&P Global Commodity Insights estimates India's data centre electricity consumption at 13 TWh in 2024, about 0.8% of national demand, and projects a near fivefold rise to 57 TWh by 2030. The International Energy Agency expects India's overall electricity demand to grow 6.4% annually through 2030, adding over 570 TWh. India's peak load has already climbed from 162 GW in 2017 to 250 GW in 2024, while installed capacity reached about 552 GW in July 2026, according to a Press Information Bureau factsheet.
S&P Global estimates that 15-30 GW of additional renewable capacity will be needed over the next five years to meet data centre demand. Operators have announced over 3 GW of renewable procurement deals for live and pipeline projects. PwC identifies power as the biggest constraint on the global buildout. A March 2026 parliamentary reply put data centre electricity demand at 13.56 GW, while an August reply cited around 17 GW. A July 2026 report noted states had submitted AI data centre projects that could add 26.3 GW of grid load.
Water and Heat Pressures
Data centres also strain water resources. A 100 MW facility consumes about 2 million litres daily, equivalent to the use of roughly 6,500 households. India's data centres used an estimated 150 billion litres in 2024-25, projected to double to 358 billion litres annually by 2030. Facilities are clustering in water-stressed regions: Rajasthan extracts 147.11% of its annual groundwater recharge, the second highest rate nationally. Telangana's Irrigation Minister confirmed in May 2026 that 16 districts faced groundwater stress, and Hyderabad's surface water supply dropped 20% during the summer of 2024, prompting rationing.
Heat is another concern. A March 2026 University of Cambridge study, analysing 20 years of NASA satellite data, found data centres raise land surface temperatures by an average of 2°C within a 10 km radius, with extremes reaching 9.1°C. Some 340 million people globally live in these affected zones. Mumbai's land surface temperature rose from 40.9°C in 2003 to 47.3°C in 2023, driven largely by urbanisation. Hyderabad's urban heat island intensity ranges from 5.74°C to 6.82°C, even as its urban area doubled between 2001 and 2020, and the city recorded temperatures above 43°C in the summer of 2024.
Grid and Policy Challenges
Maharashtra’s peak power demand hit 27,230 MW in April 2026, the highest ever handled by the state utility. Mumbai’s reservoirs stood at just 44.5% of capacity in March 2026. India curtailed 300 GW-hours of renewable energy in the first quarter of 2026 because the grid could not carry it, according to an analysis of Central Electricity Authority data by Ember Energy. Over the past five years, India has met only about 80% of its annual transmission targets, one in four major transmission schemes is running a year or more behind schedule, and 20 GW of renewable capacity faces connectivity delays exceeding four months.
The Union Ministry of Power says capacity is not the constraint; the constraint is market design and transmission infrastructure. Ember's calculations suggest 3-4 GW of two-hour storage could have absorbed most of the curtailed generation in early 2026.
State policies have been generous but increasingly cautious. Telangana classifies data centres as “essential services,” guaranteeing uninterrupted power during shortages. Maharashtra’s policy originally required 100% renewable energy for core operations but reduced to 51% in June 2026. Gujarat’s Data Centre Policy 2026-29 mandates at least 51% green energy sourcing. Karnataka’s IT minister told the State Assembly in March 2026 that the State was reviewing its policy over water and energy concerns. Tamil Nadu has linked incentives to renewable compliance.
Expert Perspectives
Vibhuti Garg, Director, South Asia at the Institute for Energy Economics and Financial Analysis (IEEFA), warned that “There is a risk that a significant part of the associated infrastructure cost could eventually be socialised.” Prateek Aggarwal, Senior Programme Lead at the Council on Energy, Environment and Water (CEEW), suggested “Governments should introduce phased power and water use standards with enforceable benchmarks.” IEEFA has also suggested that coastal locations offer advantages such as proximity to near-shore wind and solar, and access to seawater for cooling without desalination.

AI-extracted; can misattribute a claim — see Methodology.
Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
