Notes

  • India's data centre capacity increased from 520 MW in 2020 to 1.5 GW in 2026, with a projection of 6.5 GW by 2030.
  • Electricity demand for data centres is expected to rise from 13 TWh in 2024 to 57 TWh by 2030.
  • The Ministry of Power estimates AI will add 26.3 GW of power demand by 2031-32.
  • A 100 MW data centre consumes approximately 2 million litres of water daily.
  • Total annual water consumption by Indian data centres is projected to reach 358 billion litres by 2030.
  • Data centres are clustering in water-stressed regions like Rajasthan, Maharashtra, and Telangana.
  • Transmission constraints led to the curtailment of 300 GW-hours of renewable energy in Q1 2026 due to grid bottlenecks.
  • A Cambridge study indicates data centres can raise local land surface temperatures by an average of 2°C within a 10 km radius.
  • Current state policies offer incentives like tax exemptions and fast-track clearances but lack mandatory grid impact or hydrogeological assessments.
  • Proposed solutions include climate-intelligent power markets, battery storage at renewable pooling stations, and a national sustainability framework.

Part of a longer story

This is day 5 of 5 in Environmental and social impact of data centre expansion, which has been running since 26 July 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
