Sustainability in Indian Data Centers

India’s data center industry in 2025 is at a critical inflection point: rapid growth is being matched by equally strong sustainability imperatives. The sector, valued at USD 10.48 billion, is projected to nearly triple by 2032, but its environmental footprint is forcing a pivot toward renewable energy, advanced cooling, and water conservation.

Market Growth and Environmental Challenges

• The Indian data center market is projected to reach USD 27.2 billion by 2032, growing at a CAGR of 14.6%.

• Rising demand from AI workloads, cloud adoption, and 5G rollout is driving hyperscale expansions, but this growth brings challenges of high energy consumption, water usage, and carbon emissions.

• A typical 1MW facility consumes up to 25 million liters of water annually, underscoring the urgency of water-efficient cooling.

Regulatory and Policy Frameworks

• The Draft National Data Centre Policy 2025 (MeitY) proposes 20-year tax exemptions, GST input credits, and streamlined approvals for green-certified facilities.

• States like Maharashtra, Karnataka, Tamil Nadu, and Uttar Pradesh are offering subsidies, reduced tariffs, and SEZ land allocations for sustainable projects.

• National schemes such as the Green Energy Corridor and Perform, Achieve, and Trade (PAT) program incentivize energy efficiency and carbon reduction.

Energy Efficiency and Renewable Integration

• Indian operators are adopting liquid immersion cooling and AI-optimized systems, achieving PUE ratios as low as 1.3, compared to the global average of 1.5–1.8.

• AdaniConneX and Nxtra by Airtel have pledged 100% renewable energy by 2030, supported by PPAs and on-site solar installations.

• Modular and prefabricated designs are becoming mainstream, enabling rapid deployment and reduced waste.

Water Efficiency and Conservation

• The Indian Green Building Council (IGBC) promotes WUE targets below 2.2 liters/kWh, with certifications rewarding rainwater harvesting and wastewater recycling.

• Cities like Chennai and Mumbai mandate water impact assessments during approvals, aligning with Jal Shakti Abhiyan conservation goals.

Investment and ESG Compliance

• India allows 100% FDI in data centers via the automatic route, though approvals are required for investors from neighboring countries.

• ESG compliance is tightening, with mandatory Business Responsibility and Sustainability Reporting (BRSR) for large facilities.

• Global players like Google, Meta, and Tata Group are investing billions into AI-ready, renewable-powered campuses.

Recent Developments (2025)

• The Data Center Summit 2025 (IGBC) in Bengaluru highlighted AI-driven cooling, net-zero frameworks, and modular infrastructure as key enablers.

• Naxion Energy launched India’s first sodium-ion energy storage systems, offering sustainable backup solutions for data centers.

• Google’s USD 15 billion AI hub in Visakhapatnam and Reliance’s Jamnagar campus are examples of hyperscale projects embedding sustainability from inception.

Outlook

• By 2030, 30% of India’s data center capacity is expected to be powered by renewables.

• Microgrids and energy storage systems are being deployed to overcome grid constraints.

• The convergence of AI, modularity, and sustainability is positioning India as a global hub for green digital infrastructure.

India’s path to a USD 1 trillion digital economy will hinge on sustainable data centers that balance innovation with environmental stewardship. The sector is evolving into a model where AI-ready, net-zero, and water-efficient facilities are not exceptions but the new standard.
