Data Centres in India: Strategic Infrastructure for the Digital and AI Economy

Why in News? 

A PIB explainer of 14 September 2026 highlighted the rapid expansion of India's data-centre ecosystem amid rising demand from digital payments, e-governance, cloud computing and artificial intelligence. Installed capacity increased from about 375 MW in 2020 to 1.57 GW by August 2026 and is projected to approach 8 GW by 2030, alongside nearly USD 70 billion of investment underway and another USD 90 billion announced.

Data Centre — Physical Backbone of the Digital Economy

• Data Centre: A secure physical facility housing interconnected servers, storage and networking systems that store, process, manage and distribute digital information.
• Core Infrastructure: Servers provide computing power; storage systems retain data; networks provide connectivity; power and backup systems ensure continuity; cooling removes equipment-generated heat; physical and cyber controls secure infrastructure.
• Operational Requirements: Modern data centres are designed around availability, low latency and security.
• Digital Dependence: UPI, online banking, e-commerce, government platforms, cloud applications and AI services ultimately depend upon such physical computing infrastructure.

Data Centre ≠ Cloud

Data Centre → Physical infrastructure containing computing equipment.

Cloud Computing → Service model delivering computing, storage, databases and applications remotely over networks.

Cloud services rely upon physical infrastructure such as data centres, but the terms are not interchangeable.

How Digital Infrastructure Works

A typical digital request passes through:

• Load Balancer: Distributes requests among servers to prevent individual machines from becoming overloaded.
• Application Server: Executes programme logic.
• Database Server: Retrieves or updates required information.

This architecture explains why apparently instantaneous digital services require substantial underlying computing, networking, power and storage capacity.

India's Expanding Capacity

Why MW/GW? Data-centre capacity is commonly expressed in power capacity because electricity availability determines the volume and density of computing equipment that can operate continuously. This becomes particularly important for AI-oriented computing clusters, which have high power requirements.

Why Data Centres Are Strategic Infrastructure

• Digital Public Infrastructure: High-volume payments, financial services and government platforms require continuously available backend computing.
• Artificial Intelligence: Training and inference require high-performance computing, specialised accelerators, high-speed networking, storage and advanced cooling.
• Cloud Economy: Rising cloud adoption shifts computing requirements from individual enterprises towards large-scale shared data-centre infrastructure.
• E-Governance: NIC operates National Data Centres at Delhi, Pune, Hyderabad and Bhubaneswar, besides 37 smaller centres at State capitals. GI Cloud (MeghRaj) provides cloud infrastructure for government requirements.
• Digital Resilience: Domestic computing capacity can strengthen continuity of critical digital services and support domestic cloud and AI capabilities.

Important Distinction

Data Centre in India ≠ Automatic Data Localisation.

Data localisation depends on the applicable law or regulation specifying where particular categories of data must be stored or processed.

Infrastructure Status and Policy Support

The Union Budget 2022–23 included data centres in the Harmonized Master List of Infrastructure Sub-sectors, granting them infrastructure status.This recognises their characteristics:

High Capital Intensity + Large Upfront Investment + Long Asset Life + Dependence on Power and Connectivity

Infrastructure status can facilitate access to longer-term financing and reflects a wider policy shift in which digital infrastructure is increasingly treated as foundational economic infrastructure.

The Union Budget 2026–27 further proposed a tax holiday extending to 2047 for eligible foreign companies providing global cloud services through data-centre infrastructure located in India, subject to prescribed conditions. The objective is to provide long-term policy certainty and position India as a location for global cloud and AI infrastructure.

Data Centres within India's Technology Stack

Data-centre expansion is interconnected with India's wider technology ecosystem:

Semiconductors → Servers/AI Accelerators → Data Centres → Cloud/Compute → AI & Digital Applications

• IndiaAI Mission: Expanding AI capability increases demand for high-performance compute infrastructure.
• Semiconductor Ecosystem: Processors, memory and specialised accelerators provide the hardware foundation.
• Electronics Components Manufacturing: Strengthens supporting hardware supply chains.
• PLI 2.0 for IT Hardware: Supports domestic IT-hardware production, including servers.

The strength of the digital economy therefore depends on the entire technology stack, rather than data-centre capacity alone.

Energy–Water–Digital Infrastructure Nexus

• Electricity: Continuous operation requires highly reliable power; expansion towards nearly 8 GW has implications for generation, transmission and grid planning.
• Cooling: High-density computing produces substantial heat, making cooling systems essential but energy-intensive.
• Water: Some cooling technologies consume significant water, creating potential competition with urban, industrial and agricultural requirements.
• Renewable Energy: Large-scale growth increases the importance of low-carbon electricity procurement and energy-efficient hardware.
• Location Choice: Future facilities must consider power availability + fibre connectivity + water availability + environmental carrying capacity.

Thus, growth in digital infrastructure creates a physical sustainability challenge:

Building Capacity Is Not Enough

• Power Reliability: Requires robust grids, redundancy and backup systems.
• Renewable Integration: Clean-energy procurement becomes increasingly important as electricity demand rises.
• Water Security: Cooling technology should reflect local hydrological conditions, particularly in water-stressed regions.
• Cybersecurity: Concentrated computing and data infrastructure creates high-value targets requiring layered physical and digital protection.
• Connectivity: High-capacity fibre networks and network redundancy are essential.
• Skilled Workforce: Growth requires expertise in cloud architecture, networking, cybersecurity, electrical engineering, cooling and AI infrastructure.

Geographical Diversification: Excessive metropolitan concentration can intensify land, electricity and water pressure while increasing exposure to local disruptions.
