Discuss the energy and environmental challenges of India's rapid data centre expansion. How can policy reconcile hyperscaler demand with India's climate commitments?

India's installed data centre capacity reached 1.57 GW in August 2026 and is projected to reach nearly 8 GW by 2030 [1]. Most of this growth comes from AI and hyperscale cloud firms, and it needs a lot of power and water. Policy should therefore guide where and how this growth happens, not just subsidise it.

Energy challenges

• Fast-rising demand: capacity grew from about 375 MW in 2020 to about 1,500 MW in 2025 [2]. The Central Electricity Authority projects that demand could reach 17 GW by 2031–32 [1]. This will strain grids that also serve homes and industry.
• Need for constant power: data centres must run without interruption. Solar and wind power vary through the day, so without storage, operators fall back on a grid that still relies mostly on coal.
• States competing on subsidies: S&P Global's state ranking treats electricity as a full incentive pillar [7]. When states compete to offer the cheapest power, they can lock in high, fossil-based demand.

Environmental challenges

• Water for cooling: groundwater use by data centres falls only under the Ministry of Jal Shakti's general extraction guidelines (2020, amended 2023) [3]. There are no rules specific to data centres.
• Weak monitoring: the government told the Rajya Sabha it had received no concerns about data centre water use [3]. This more likely reflects the lack of mandatory reporting than a lack of water stress.
• Gap in the state rankings: none of the ranking's four pillars measures sustainability [7]. States are rewarded for incentives, not for environmental outcomes.

Reconciling growth with climate goals

• Tie cheap power to green power: states should give power subsidies only for renewable energy bought through open access. This would serve the draft national policy's aim of energy-efficient, green data centres [5].
• Use TRAI's two-list model: the Data Centre Incentivization Scheme (DCIS) has central incentives in one list and guidelines for state fiscal incentives in the other [4]. Sustainability conditions can be built into these guidelines. TRAI's proposed Data Centre Readiness Index (a ranking of states) should also score sustainability [4].
• Mandatory standards and disclosure: build on TRAI's proposed green data centre certification [4] and require operators to report their water and power use.
• Link central tax benefits to efficiency: the tax holiday up to 2047 already applies only to facilities notified by MeitY [6]. Efficiency norms could be made part of that notification.
• Better cooling technology: liquid, adiabatic and immersion cooling reduce water use [3].

Data centres are the backbone of Digital India and AI, but their power and water use can undercut climate goals if subsidies alone drive their growth. India can attract hyperscalers and still meet its net-zero 2070 commitment and SDGs 7, 9 and 13 if it makes incentives depend on renewable power, efficiency and open reporting of water use.
