Unlocking Future Growth in India’s Evolving Data Center Market Landscape

• The Green Transition to Sustainable Digital Infrastructure
  There is a monumental shift towards sustainability, creating a demand for green data centers. Opportunities abound in developing facilities powered by renewable energy, with a growing number of operators signing long-term Power Purchase Agreements (PPAs) for solar and wind energy. In 2024, data centers accounted for over 1.5 GW of renewable energy contracts. Investment through green bonds for financing sustainable data center projects is also gaining traction, with more than $500 million in green financing raised in 2024 for Indian digital infrastructure projects. Companies achieving low Power Usage Effectiveness (PUE) ratings below 1.4 command a premium, opening a market for energy-efficient technologies and operational expertise.
• The Rise of High-Density and Liquid Cooling Solutions
  The AI revolution necessitates a move towards high-density racks that current air-cooling technologies cannot efficiently manage. A significant opportunity in the India data center market lies in deploying advanced liquid cooling solutions, including direct-to-chip and immersion cooling. The demand for these technologies is projected to surge, with related infrastructure spending expected to exceed $200 million by 2025. Data centers capable of supporting rack densities above 30 kW are becoming essential. Developing expertise and offering solutions in a "cooling-as-a-service" model presents a lucrative new revenue stream for specialized providers.

Top 2 Core Drivers Defining Market Demand

Digital Public Infrastructure and 5G Create Unprecedented Data Velocity and Volume

India's world-class Digital Public Infrastructure (DPI) and the rapid rollout of 5G are generating data at a colossal scale, fundamentally reshaping demand in the India data center market. The Unified Payments Interface (UPI) is a primary driver, with monthly transactions regularly exceeding 14 billion in 2024. Projections show UPI is on track to process over 2 billion transactions per day by 2028. Concurrently, the number of 5G subscribers in India surpassed 150 million in early 2025. Each 5G user is expected to consume over 40 gigabytes of data monthly by the end of 2025.

These platforms create a continuous, high-velocity stream of data requiring real-time processing and secure storage. The Aadhaar system processed over 80 million authentication requests daily in 2024, while the DigiLocker platform now serves over 250 million registered users. The number of active FASTag devices for electronic toll collection exceeded 85 million in 2024, generating millions of daily transaction records. Furthermore, the number of connected IoT devices in India is forecasted to reach 5 billion by the end of 2025, creating a massive new wave of data from sensors and smart devices that require localized processing power.

OTT Media and Online Gaming Boom Drives Low-Latency Infrastructure Demand

The explosive growth of digital entertainment, specifically Over-The-Top (OTT) media and online gaming, is carving out a distinct and critical demand segment within the India data center market. The number of active online gamers in India is projected to exceed 650 million by 2025. In parallel, the country's paid OTT subscriber base crossed 120 million in early 2025, with a significant portion subscribing to multiple services. The average daily time spent on OTT platforms surpassed 90 minutes per user in 2024, driving immense data consumption. The total number of hours of regional OTT content produced in 2024 grew by over 1,500 hours.

The India data center market is intensely sensitive to latency, creating a non-negotiable requirement for edge data centers and robust Content Delivery Networks (CDNs). India’s esports audience size is forecasted to grow to over 50 million viewers by 2025, an activity where milliseconds of delay can impact outcomes. Consequently, investments in edge computing infrastructure are rising, with over 30 new edge locations planned for 2025. The number of cloud gaming users also saw a substantial increase, reaching over 15 million in 2024. Data consumption for video streaming alone accounted for over 12 exabytes of data in 2024, mandating high-performance infrastructure to ensure a seamless user experience.

Segmental Analysis

BFSI Sector's Dominance Quantified by Transactions and Spending

The BFSI sector's leadership position in the India data center market with over 32.80% is vividly illustrated by its staggering digital transaction volumes. In fiscal year 2025, the Unified Payments Interface (UPI) alone processed over 11,761 crore transactions valued at ₹180.24 lakh crore, all of which require robust data center processing and storage. The total volume of all digital transactions surged by 34.8% in the same period, reaching a total value of Rs 2,862 lakh crore, highlighting the immense data load generated by the financial sector. This growth in digital payments is a primary driver for the sector's 18% share in data center user demand.

• The BFSI sector's market capitalization has surged over 50 times in two decades, from Rs 1.8 trillion in 2005 to Rs 91 trillion in 2025.
• Digital payments in India are projected to have over 130 billion transactions by the end of 2025.
• The total IT spending in India is projected to reach US$ 138.9 billion in 2024, with the BFSI sector being a major contributor to data center systems spending.

The financial industry's commitment to digital transformation extends beyond transaction processing to significant investments in IT infrastructure. Data localization regulations compel BFSI firms in the India data center market to store sensitive financial data within India, further fueling the demand for domestic data center capacity. This regulatory push, combined with the sector's continuous innovation in areas like online banking, AI-driven analytics, and fraud detection, ensures its sustained, high-volume consumption of data center resources. The market for AI in the BFSI industry was valued at USD 20 billion in 2022 and is forecasted to grow, indicating future needs for high-density, powerful data centers.

Server Hardware Dominance Measured in Racks and Investments

The server segment's significant 37.05% revenue share in the India data center market is a direct result of massive capital deployment and the physical build-out of digital capacity. To meet escalating demand, the planned capex for data centers is expected to surpass Rs 5 lakh crore in the next five years, a substantial portion of which is dedicated to server procurement. The demand for high-performance computing to handle AI workloads is pushing average rack densities from a previous average of 8-10 KW/rack towards 30 KW/rack, requiring more advanced and powerful servers. This hardware revolution is reshaping facility design as operators pivot to support racks that could exceed 100 kW.

• Hyperscalers like Google, AWS, and Microsoft are expected to drive 80% of the market growth between 2024 and 2027, focusing heavily on server infrastructure.
• To support new AI hardware, facilities are being upgraded for higher floor loads, increasing from legacy standards to between 2,200-2,500 kg/m2 .
• "Make-in-India" initiatives are gaining traction, with companies like Netweb Technologies launching advanced servers powered by AMD EPYC processors to boost local manufacturing.

The sheer scale of investment in the India data center market underscores the server's central role. Between 2019 and 2024, the industry attracted investment commitments of approximately $60 billion, with a significant amount allocated to hardware. Global technology giants are increasingly adopting an "own-and-operate" model, allowing for greater control over their server infrastructure. For instance, Google is developing a 381,000 sq ft, 8-story data center in Navi Mumbai, set for completion by 2025, which will be filled with server racks to power its cloud services.
