India's Data Center Revolution: A Decade of Transformation

The Indian data center sector is undergoing a monumental transformation, powered by innovations such as Artificial Intelligence (AI), Cloud Computing, 5G Services, Data Localization Laws, and Digital Public Infrastructure. Forecasts show that the amount of data stored in India will grow from approximately 1.5 Gigawatts today to about 14 Gigawatts by 2035, positioning India to be one of the leading global Data Hubs.

As digitization of the Indian economy continues at a fast pace, Data Centers are becoming an integral part of the National Infrastructure, similar to roads, transport systems, trade ports, and electric utilities. This is due to the significant volume of data now being created by enterprises, individuals, and government agencies. Over the coming ten years, we will see tremendous investment, technological application, and increased geographic footprint for the Data Center Ecosystem within India.

Market Expansion and Investment Outlook

Over the next ten years, India’s data center capacity is expected to grow at an expected 20% CAGR, one of the highest globally. Total investments are projected to exceed USD 65-70 billion, driven by hyperscalers, colocation providers, infrastructure funds, and real estate developers. India will transition from a capacity-constrained market to a hyperscale-ready digital backbone. Installed capacity will grow from 1.5 GW today to approximately 14 GW by 2035. Data centers will evolve from IT assets into critical digital infrastructure.

This expansion is powered by: - Rising cloud adoption across BFSI, IT, manufacturing, and government. - AI and Machine Learning workloads require high-density infrastructure. - Data localization and digital sovereignty mandates. - Growth of OTT, gaming, fintech, and e-commerce platforms.

Data Center Classification

Data centers in India are classified into three main categories: - Hyperscale DCs: AI and cloud workloads. - Co-location DCs: Secure enterprise infrastructure. - Edge Data Centers: Low-latency services in Tier 2 & 3 cities.

The economic contribution of the data center sector is significant, contributing 11.74% to GDP (Rs. 0.402 million in FY 23) and expected to hit 20% by FY29.

Rise of Hyperscale & AI-Ready Data Centers

In the next ten years, hyperscale data centers will continue to expand at an exponential rate to provide for the training of artificial intelligence (AI), cloud computing technology, and enterprise computing applications. These facilities will take the form of large campuses with most having a power capacity of between 200 MW and 500 MW. Each facility will be equipped with state-of-the-art cooling systems to handle higher density racks of computing equipment and redundant power infrastructures. India is likely to become the preferred location for global cloud regions and AI computational infrastructure.

There are three major trends regarding data center development in this area: - The growth in AI workloads is driving higher cooling and power needs. - The shift to liquid cooling and lower latency architecture. - The incorporation of renewable energy and energy-efficient designs.

Geographic Diversification & Policy Support

The main cities in Tier 1 will continue to be leaders in technology investment; however, with lower cost of land, enhanced interconnectivity, and the increasing demand for edge computing, Tier 2 cities are poised to experience the greatest opportunities for growth. Sound policies of the federal and state governments regarding tax, depreciation, GST credits, and sustainability incentives will further increase the level of confidence investors have in these markets.

Citywise Data Center Growth Comparison (Next Decade)

Over 90% of the capacity is currently concentrated in Tier 1 cities due to power security and enterprise proximity. Here’s a city-wise breakdown of data center growth:

- Mumbai: Primary DC hub with submarine cable landings, BFSI demand, and cloud regions. It will remain India’s largest DC market. - Chennai: International gateway with SEA connectivity and hyperscaler interest, becoming a top hyperscale and AI hub. - Hyderabad: Fastest-growing hyperscale city with pro-DC policies and land availability, becoming a major cloud and AI campus hub. - Bengaluru: Enterprise and startup hub with IT services, SaaS, and R&D demand, focusing on enterprise DC growth. - Delhi – NCR: Enterprise and (DR) disaster recovery hub with government, BFSI, and colocation demand, forming a strong secondary DC market. - Pune: DR and colocation with proximity to Mumbai and enterprise demand, showing mid-size stable growth. - Kolkata: East India gateway with regional connectivity and emerging demand, experiencing gradual but steady expansion. - Ahmedabad: Emerging hyperscale city with industrial growth and power availability, becoming a strong Tier 2 contender. - Kochi / Vizag: Edge and cable-linked cities with submarine cables and low latency, strategic edge DC locations. - Jaipur / Indore / Coimbatore: Edge data centers with 5G, smart cities, and OTT, showing high growth in edge markets.

Sustainability Will Become Non-Negotiable

Power consumption will rise sharply, making green energy integration mandatory. Future data centers will focus on renewable PPAs, water-positive campuses, waste heat recovery, carbon credit monetization, and ESG-linked compliances. These centers will be a combination of energy infrastructure and a digital backbone.

New Business Models Will Emerge

Data center REITs and infrastructure investment trusts (InvITs) will be built to suit hyperscale campuses, data embassies, sovereign cloud zones, and integration with industrial corridors and digital cities.

India’s Global Position by 2035

India will be a preferred APAC data center destination with a hub for AI, cloud, fintech, and digital public platforms. It will be one of the top 5 global data center markets by capacity growth, a strategic alternative to China and saturated Western markets. Total investments may reach approximately 70 billion by FY35, expected from data center operators, infrastructure developers, global hyperscalers, and institutional investors.

Final Outlook

The next decade will redefine India’s data center industry from a niche IT segment into a cornerstone of the digital economy. With hyperscale expansion, policy support, sustainability focus, and Tier 2 city penetration, India’s data center market will be larger, greener, smarter, and globally indispensable. India’s data center industry will cease being an ancillary business by 2035 and will become a key component of India’s Digital Economy, fueling technological innovation, economic development, and digital sovereignty.
