Redefining Data Centers: A Sustainable Future with Renewable Energy
India's growing data consumption demands a sustainable approach to data center development. By co-locating data centers near renewable energy sources, we can ensure energy efficiency, reduce transmission losses, and promote environmental and economic resilience.

India is the world’s second-largest consumer of data, yet its data center capacity remains disproportionately low - less than 1% of the global total. Rapid digital adoption driven by AI, IoT, cloud services, and streaming is propelling unprecedented demand. This creates a unique opportunity to build data infrastructure that is not only scalable but also sustainable, embedding energy efficiency, renewable integration, and operational resilience at its core.
Pioneering initiatives in states with abundant renewable energy capacity are raising the bar for sustainability, demonstrating how infrastructure can be designed to minimize environmental impact and maximize economic value. However, true sustainability requires a fundamental rethink of where and how data centers are developed, with a focus on power source proximity and system integration.
The Power-Centric Reality of Metro Growth
Metropolitan hubs like Mumbai dominate data center capacity growth due to connectivity and investment. By 2025, Mumbai alone is expected to host more than half of India’s data center capacity. Data centers here already consume nearly 20% of the city’s peak power demand, which is around 700 MW, with projections to rise further, significantly stressing an electrical grid stretched near its limits.
This challenge extends beyond just supply. Large data centers require substantial backup diesel generator capacity, often equivalent to their load. Operating these DG sets in dense urban areas creates environmental concerns, including air pollution and noise, affecting communities. Additionally, pursuing on-site renewable energy and Battery Energy Storage Systems (BESS) to achieve carbon neutrality presents daunting challenges, including the need for expansive land areas (potentially hundreds of acres for a 100 MW facility) far beyond what cities can accommodate.
Rethinking Sustainability Beyond Greenwashing
Sustainability cannot rely solely on purchasing renewable energy certificates or procuring power from distant renewable farms. True decarbonization depends on co-locating data centers with renewable energy generation and integrating with local grid dynamics. Concentrated industry demand strains power availability and urban land, threatening economic resilience and quality of life. To truly decarbonize, data centers must be physically co-located near renewable energy sources. This approach reduces transmission losses and improves the transparency and verification of clean energy use.
Embracing Distributed Growth Aligned to Renewables
States with robust renewable policies and abundant nearby clean power, such as Tamil Nadu, Gujarat, Karnataka, exemplify the benefits of distributed data center development. These regions boast robust renewable energy policies and greater land availability in proximity to solar and wind plants, enabling data centers to draw power directly from clean grids. This not only minimizes losses but enables transparent, verifiable sustainability claims.
Further, geographic diversification supports not only energy resilience but reduces dependency on long-distance fiber optic networks, bolstering overall digital infrastructure robustness. This distributed model balances load, mitigates risks, and fosters inclusion and economic growth beyond the metros.
A Collective Industry Mandate
The data center industry cannot afford to remain anchored to legacy real estate-centric growth models. Power - availability, and quality of energy, is by far the critical limiter and enabler of sustainable expansion. As industry leaders, we must embed sustainability into every decision, prioritizing renewable proximity and transparency over mere compliance. If done thoughtfully, India’s data centers can set global standards, proving that rapid digital growth and climate responsibility are inseparable pillars of progress.
India’s data center industry can lead with vision and integrity, proving that digital growth and climate responsibility are not just compatible but mutually reinforcing. Together, we can build a digital future powered by clean energy and purpose-driven innovation.
