India’s rapid digital transformation is creating an unprecedented demand for computing power, data storage and high-speed connectivity, placing data centres at the heart of the country’s digital infrastructure. From online banking and digital payments to e-Governance, cloud computing and Artificial Intelligence (AI), these largely invisible facilities are increasingly powering the services that underpin everyday life and economic activity.
As digitalisation expands across sectors, the Government is building a policy and infrastructure ecosystem aimed at strengthening India’s data-centre capacity, improving access to finance, attracting investment, promoting clean energy and ensuring more efficient use of electricity and water.
The infrastructure behind India’s digital life
A data centre is a secure facility that houses computing, storage and networking equipment used to store, process, manage and distribute vast quantities of digital information.
Modern data centres bring together multiple systems – including servers, storage equipment, networking infrastructure, power supply, cooling, cybersecurity and management software – to ensure that digital services remain available continuously and securely.
Reliable electricity is fundamental to their operation. Data-centre computers cannot simply be switched off, even for a fraction of a second. Uninterruptible Power Supplies (UPS) provide immediate backup during power interruptions, while generators and electrical distribution systems provide resilience during longer disruptions.
Cooling is equally important because continuous computing generates substantial heat. Heating, Ventilation and Air Conditioning (HVAC) systems regulate temperature and airflow, while advanced airflow management and liquid-cooling technologies are increasingly being deployed to improve thermal efficiency.
At the core of the facility, servers process information and run applications, while Hard Disk Drives (HDDs) and Solid-State Drives (SSDs) store large volumes of data. Routers and high-speed switches enable communication within and outside the facility, with fibre-optic connections providing high-speed links to external networks.
Security systems protect both physical infrastructure and digital assets, while management software monitors operations and optimises computing resources. Virtualisation allows multiple virtual machines to operate on a single physical server, improving utilisation. Automation tools help manage workloads, maintenance and the detection of operational problems.
From a click to a response in seconds
The complexity of a data centre becomes almost invisible when a user checks a bank balance, opens an application or accesses a digital document.
A typical digital request first passes through a security layer, which checks the request and guards against cyber threats. A load balancer then directs the request to an available server so that no individual server becomes overloaded.
The application server processes the request and determines what information or service is required. Where necessary, an Application Programming Interface (API) enables communication with another application or service.
The database server retrieves the required information and sends it back to the application server. The processed response then travels through the network to the user’s device.
The entire chain can take just one to two seconds.
The sequence – connect, receive, network, process, store, secure and respond – allows cloud platforms, e-Governance systems and AI applications to deliver services rapidly and reliably at scale.
In simple terms, the network acts like corridors connecting different teams; the security layer functions as a security guard; the load balancer works like a traffic cop; the application server acts like a chef preparing an order; the API serves as a messenger; and the database server functions as a digital vault.
This interconnected architecture makes modern data centres much more than storage facilities. They are the underlying infrastructure supporting India’s expanding digital economy.
India’s data-centre capacity expands rapidly
India’s data-centre ecosystem has developed alongside the growth of e-Governance and digital services.
The National Informatics Centre (NIC) has established state-of-the-art National Data Centres at its headquarters in Delhi and in Pune, Hyderabad and Bhubaneswar. It has also established 37 smaller data centres at various State Capitals, providing digital infrastructure to government institutions at different levels.
These facilities support round-the-clock operations, system management and skilled on-site personnel, helping government services remain available to citizens and institutions.
The wider commercial data-centre sector has also witnessed rapid expansion. Installed data-centre power capacity, which stood at around 375 MW in 2020, increased to 1.57 GW as of August 2026. It is projected to reach nearly 8 GW by 2030.
The scale of investment reflects growing confidence in India’s digital infrastructure market. Nearly USD 70 billion in investments are already underway, while another USD 90 billion in projects have been announced.
Infrastructure status gives the sector a stronger financial foundation
Recognising the strategic importance of data centres, the Government included them in the Harmonized List of Infrastructure in the Union Budget 2022–23, giving the sector infrastructure status.
The move enables data-centre projects to gain greater access to credit and long-term financing. In practical terms, infrastructure status places data centres in the same broad infrastructure financing framework as major assets such as highways, airports and power networks, supporting investment and capacity expansion.
The Union Budget 2026-27 further strengthened the investment environment by introducing a tax holiday for eligible foreign cloud service providers until 2047. The incentive applies to global operations using India-based data-centre infrastructure and covers Tax Years 2026-27 to 2046-47 for notified foreign companies.
Together, these measures are intended to make India a more attractive destination for cloud infrastructure and data-centre investments.
Semiconductor and AI ecosystems reinforce data-centre demand
The growth of data centres is closely linked with developments in other strategic technology sectors.
The second phase of the Semicon India Programme, or Semicon 2.0, approved by the Union Cabinet on July 15, 2026, has an outlay of ₹1,27,500 crore under the India Semiconductor Mission. The programme aims to develop a trusted and resilient semiconductor ecosystem in the country.
The IndiaAI Mission, with a total budget outlay of ₹10,371.92 crore, is another major driver of demand for computing infrastructure. As AI applications expand, the requirement for high-performance computing, storage and data-processing capacity is expected to increase correspondingly.
The Electronics Components Manufacturing Scheme (ECMS) has also received enhanced financial support, with its allocation increased from ₹22,000 crore to ₹40,000 crore.
Meanwhile, PLI Scheme 2.0 for IT Hardware is aimed at building a stronger domestic manufacturing ecosystem for products such as servers, attracting investment, reducing import dependence and positioning India as a trusted global supply-chain hub.
Energy emerges as a critical requirement
The rapid expansion of data-centre capacity also brings a growing requirement for reliable electricity.
According to the Central Electricity Authority under the Ministry of Power, electricity demand from data centres could reach 17 GW by 2031–32.
With data centres operating continuously, ensuring adequate power supply while limiting their environmental footprint is becoming an increasingly important policy consideration.
The Government is promoting renewable and cleaner energy through measures including the Green Energy Open Access Rules, Green Energy Corridor Scheme and National Green Hydrogen Mission. The National Programme on High Efficiency Solar PV Modules and the Solar Park Scheme are also supporting clean-energy deployment.
These initiatives can help energy-intensive digital infrastructure gain access to cleaner and more reliable electricity as the sector scales up.
Nuclear power and the SHANTI Act
The Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Act is expected to further strengthen the clean-power ecosystem.
The framework supports reliable nuclear power for emerging energy-intensive sectors, including AI and data centres, while creating scope for the future deployment of Small Modular Reactors and Micro Nuclear Reactors.
For an industry that requires continuous power, a diversified clean-energy mix can become an important component of long-term infrastructure planning.
Making data centres more resource-efficient
As the physical footprint of data centres grows, energy and water efficiency are becoming increasingly important.
The Bureau of Indian Standards (BIS) has developed standards for data-centre efficiency through its technical committee LITD 31, which covers cloud computing, information technology and data centres.
These standards include Power Usage Effectiveness (PUE), Carbon Usage Effectiveness (CUE), Cooling Efficiency Ratio (CER) and Water Usage Effectiveness (WUE).
PUE and WUE can be understood as efficiency indicators showing how effectively a facility uses electricity and water. CUE measures carbon emissions associated with the electricity used by a data centre, while CER assesses the efficiency of its cooling systems.
The Bureau of Energy Efficiency has also notified the Energy Conservation Building Code (ECBC) 2017 and the Energy Conservation and Sustainable Building Code (ECSBC) 2024, which prescribe energy-efficiency and water-conservation requirements for buildings, including provisions relevant to data-centre infrastructure.
Advanced cooling technologies reduce resource pressure
Cooling requirements vary depending on the technology deployed in a data centre. With AI workloads generating greater computing intensity and heat, advanced cooling technologies are gaining importance.
These include direct-to-chip liquid cooling, adiabatic cooling and immersion cooling, along with closed-loop liquid-cooling systems designed to improve resource efficiency.
Groundwater extraction, including for industrial purposes, is regulated under guidelines issued by the Ministry of Jal Shakti, adding another layer of resource governance as data-centre infrastructure expands.
Building a resilient and sovereign digital foundation
India’s data-centre expansion represents more than an increase in computing capacity. It is becoming an important component of the country’s broader effort to build resilient and sovereign digital infrastructure.
A stronger data-centre ecosystem can support data sovereignty, digital trust, economic competitiveness and technological self-reliance, while the growth of cloud and AI infrastructure creates opportunities for innovation and new economic activity.
At the same time, rapid expansion brings the need for responsible governance of data, technology, energy and digital infrastructure. Strong standards, robust cybersecurity, responsible data practices and efficient resource management will be essential to ensure that growth remains sustainable and secure.
The development of domestic capabilities in computing, semiconductors, energy and other critical digital technologies will further strengthen this ecosystem.
As India advances towards Viksit Bharat by 2047, data centres are emerging as a foundational layer of the digital economy—quietly powering the banking transactions, government services, cloud applications and AI systems that are increasingly becoming part of everyday life.
