A comprehensive guide on starting a data center in India

Why India, Why Now

India’s digital infrastructure is growing at a staggering pace. The market is currently valued at USD 10.48 billion and is projected to triple by 2032.

The country's data center capacity grew from 350 MW in 2019 to over 1,030 MW by 2024 nearly tripling in five years and is projected to reach 1,825 MW by 2027. The market itself is valued at approximately USD 10.48 billion and is projected to nearly triple by 2032, growing at a CAGR of 14.6%.

What is driving this? This massive expansion is fueled by a perfect storm of digital demand. India has the highest mobile data consumption globally, with over 96.6 crore (966 million) active internet connections. Rapidly expanding 5G networks, cloud adoption, and heavy AI workloads. New data localization laws legally force companies to store Indian users' data within the country. For investors and entrepreneurs, building data centers in India is a massive golden opportunity but executing it is highly complex.

The regulatory and compliance landscape

Before a single brick is laid, you need to understand what laws govern data centers in India. The regulatory framework spans central legislation, sector-specific directives, and a patchwork of state-level policies.

The IT Act, 2000

This act mandates "reasonable security practices" for protecting sensitive personal data. Section 70B of the Information Technology (Amendment) Act, 2008 established CERT-In the Indian Computer Emergency Response Team as the national agency for cybersecurity incident response, and mandates rapid incident reporting; an obligation that is significantly easier to fulfill when infrastructure is located within the country.

The DPDP Act, 2023 (and 2025 rules)

India’s primary data privacy law forces "data fiduciaries" (companies managing data) to implement strict safeguards. Non-compliance or data breaches can trigger fines up to ₹250 crore. In a breach, operators must report to both CERT-In and the Data Protection Board of India. This gives the government power to restrict cross-border data transfers, making local Indian data centers essential.

CERT-In Directions (2022 and Beyond)

CERT-In's mandatory cybersecurity directives set the most operationally stringent day-to-day requirements for data center operators. Key obligations include:

• 6-hour incident reporting window: Any cybersecurity incident must be reported to CERT-In within six hours of detection one of the tightest timelines globally.
• 180-day log retention: Logs from firewalls, intrusion detection systems, servers, and network devices must be retained for at least 180 days and stored within Indian jurisdiction.
• Annual third-party audits: Organizations must undergo cybersecurity audits at least annually or after significant infrastructure changes, covering IT, OT, cloud, supply chain, and physical security domains.
• NTP synchronization: All system clocks must be synchronized to National Informatics Centre (NIC) or National Physical Laboratory (NPL) time servers.

Clearances and Permits: The red tape

The reality check, facilities larger than 20 MW typically require up to 30 separate clearances, adding 12 to 18 months to pre-construction timelines. Approval speed varies wildly by state.Key permits typically required include:

• Land use/zoning change approval from local urban development authority
• No-objection certificates (NOCs) from fire safety, civil aviation (if near airports), and pollution control boards
• Electricity supply agreement with the state DISCOM
• Water extraction or supply approvals (critical and often underestimated)
• Building plan approvals under local municipal bodies
• Environmental clearance for large facilities under EIA Notification, 2006

Government schemes and financial incentives

The Government of India and multiple state governments have put in place a meaningful set of financial and non-financial incentives to attract data center investment. Understanding these can materially alter your project economics.

Infrastructure Status (Central Government)

In October 2022, data centers were granted "infrastructure" status and included in the Harmonized Master List of Infrastructure Sub-sectors. This is highly significant because an infrastructure status grants data center developers access to long-term, lower-cost financing from domestic banks and development finance institutions, on terms that would otherwise be unavailable for commercial real estate projects.

Draft National Data Centre Policy and the DCIS

The Draft National Data Centre Policy (MeitY, 2020) proposed a Data Center Incentivization Scheme (DCIS) to provide targeted fiscal support. While the national policy remains in draft form, several of its components are being operationalized at the state level and through budget measures. The Draft National Data Centre Policy 2025 has proposed 20-year tax exemptions, GST input tax credits on capital assets (including cooling, HVAC, and electrical systems), and streamlined approvals for green-certified facilities.

The government is reportedly considering a 15% concessional tax rate for data center investments similar to the concession given to new manufacturing units, alongside 20-year tax incentive windows and potential zero-tax status for cloud data centers established through 2047. Foreign firms leasing or operating at least 100 MW of capacity may be eligible for permanent establishment status in India, encouraging deeper investment commitments.

State-level policies

With the national policy still in draft form, states have taken the lead, and 15 states have notified dedicated data center policies. The competition among states for data center investment is fierce, and the incentives vary considerably:

• Maharashtra: Single-window clearance, stamp duty exemptions, electricity duty waivers, and industrial zone land allocation. The Navi Mumbai corridor has become India's largest data center cluster.
• Telangana: Stamp duty rebates, power at preferential tariffs, and subsidized land in designated IT zones. Data centers are classified as essential services under the state's Essential Services Maintenance Act, ensuring operational continuity.
• Karnataka: Incentives for data centers in non-Bengaluru locations to ease pressure on Bengaluru's infrastructure, alongside power tariff concessions for large consumers.
• Tamil Nadu: Land at preferential rates, electricity tariff subsidies, and a single-window clearance system.
• Andhra Pradesh: Its Data Centre Policy 4.0 (2024 - 2029) explicitly targets an additional 200 MW of capacity, with land allotment and fiscal support for hyperscale and AI-ready facilities. The state also promotes seawater cooling for coastal data centers, leveraging its natural geography. Google's USD 15 billion, 1 GW AI data center investment in Visakhapatnam reflects the effectiveness of this approach.
• Haryana: Municipal building norm exemptions, self-certification for compliance under labour laws, and single-window clearance with strict timelines.
• Uttar Pradesh, Odisha: Essential service classification and infrastructure subsidies.

Non-financial incentives are equally important: many states allow data center operators to self-certify compliance under labour legislations such as the Factories Act and the Shops and Establishments Act, significantly reducing ongoing compliance overhead.

Considering this, engaging with multiple state investment promotion agencies simultaneously. The incentives are negotiable for large projects, and states actively compete on headline terms. Anchoring negotiations around power tariff commitments, as electricity is the dominant long-term operating cost.

Selecting the right location: geography, risk, and connectivity

Choosing the right location is one of the most important decisions when building a data center. A poor site can create long-term operational and financial disadvantages that cannot be fixed through engineering alone.

India's climate vulnerability: the risk matrix

India's geography presents significant risks for data centers. Studies published in 2025 show that around 72% of districts face extreme flood risk, while 57% are vulnerable to extreme heat. Flooding can damage critical infrastructure, while high temperatures increase cooling costs and reduce energy efficiency.

Key factors to evaluate include:

• Seismic risk: India is divided into seismic Zones II to V. Zone V carries the highest earthquake risk, while the western Deccan Plateau, including Pune, Hyderabad, and Bengaluru, falls largely in Zones II and III, making it one of the country's most stable regions for data centers.
• Cyclones: The east coast, including Odisha, Andhra Pradesh, and Tamil Nadu, regularly experiences cyclones, while Maharashtra and Gujarat face less frequent but stronger storms. Coastal sites require enhanced protection and disaster planning.
• Flooding: River floodplains around Delhi, Patna, and Kolkata have higher flood risk, requiring elevated construction, stronger drainage systems, and higher insurance coverage.
• Extreme heat: Rajasthan, Gujarat, and parts of the Indo-Gangetic plain often exceed 45°C during summer, significantly increasing cooling costs.

Established data center hubs and their trade-offs

• Mumbai / Navi Mumbai: India's largest data center market with excellent international connectivity through submarine cable landing stations. However, land costs, flood risk, and power constraints remain challenges.
• Bengaluru: Offers a cooler climate, lower cooling costs, and India's strongest technology talent pool, but faces power reliability issues, water scarcity, and expensive real estate.
• Hyderabad: A fast-growing hub supported by favorable policies, lower land costs, reliable power, and low seismic risk. Careful site selection is needed to avoid flood-prone areas.
• Chennai: Benefits from strong connectivity and a large IT ecosystem but faces cyclone exposure, flooding, and high humidity that complicates cooling.
• Pune: Provides lower land costs than Mumbai, good engineering talent, and favorable climate conditions while maintaining proximity to Mumbai's connectivity.
• Emerging Tier-2 cities: Visakhapatnam, Noida, Kolkata, and Raipur are attracting investment due to lower costs and government incentives, though power reliability and network redundancy require careful evaluation.

Connectivity infrastructure

Mumbai, Bengaluru, Chennai, and Hyderabad provide the strongest digital infrastructure, with access to submarine cable landing stations, multiple Internet Exchange Points (IXPs), and diverse fiber networks. Proximity to major cloud regions and NIXI points of presence can improve competitiveness.

Every data center should have at least two independent fiber connections from different providers. Relying on a single fiber path is not acceptable for Tier III or Tier IV facilities.

Key components of a data center

A data center consists of multiple interconnected systems that must be designed to meet the desired level of uptime and reliability. Most commercial facilities in India are built to Tier III (99.982% availability) or Tier IV (99.995% availability) standards.

Physical infrastructure

1. Building and civil works: The facility must comply with India's National Building Code (NBC) and is typically built as a reinforced concrete structure with high floor load capacity (1,000 - 2,000 kg/m²), raised floors or overhead cable management, and fire-rated separation between IT, power, and cooling areas.
2. Power infrastructure: Power systems are the largest capital expense, accounting for 35 - 45% of total CapEx. Key components include:

• High-voltage grid supply (typically 33 kV or 66 kV) with dedicated substations
• Diesel generators providing full backup power with N+1 or 2N redundancy
• UPS systems supplying 10 - 15 minutes of battery backup during power transitions
• Rack-level Power Distribution Units (PDUs)
• Battery Energy Storage Systems (BESS), increasingly used for AI workloads and renewable energy integration

3. Cooling infrastructure: Cooling consumes around 40% of a data center's energy in India. Common solutions include:

• CRAC/CRAH units for standard rack densities (3 - 10 kW per rack)
• Chiller plants with cooling towers for large facilities
• Adiabatic and free cooling, effective in cooler locations like Bengaluru
• Liquid cooling, essential for AI and HPC workloads exceeding 30 - 50 kW per rack. It can reduce overall power consumption by 10 - 15% and is necessary for racks exceeding 100 kW.

4. Network infrastructure: Reliable connectivity requires at least two physically separate fiber entry points, core and aggregation switches, and for colocation facilities, a Meet-Me Room (MMR) for customer and carrier interconnections.

5. Security infrastructure: Physical security includes perimeter fencing, CCTV with at least 90 days of storage, biometric access controls, and 24×7 security personnel.

6. Monitoring and management: Data Center Infrastructure Management (DCIM) software provides centralized monitoring of power usage, environmental conditions, capacity planning, and incident management, helping maintain efficient and reliable operations.

CapEx and OpEx

India offers a significant cost advantage for building data centers, although rising demand for power, land, and skilled talent is gradually narrowing the gap.

1. Capital expenditure (CapEx): A greenfield data center in India typically costs INR 40 - 45 crore (USD 4 - 5 million) per MW, around 45% cheaper than global averages. In 2025, installation costs averaged USD 7/W in India, compared with USD 10/W in the US and USD 11/W in the UK. Typical CapEx distribution:

• Electrical systems (UPS, transformers, DG sets, switchgear): 35 - 40%
• Cooling infrastructure: 25 - 30%
• Civil and structural works: 15 - 20%
• IT infrastructure (networking, cabling, DCIM): 5 - 8%
• Security systems: 3 - 5%
• Design, permits, and project management: 5 - 8%

Achieving Tier III or Tier IV certification typically increases infrastructure costs by 20 - 30% due to additional redundancy requirements.

2. Operational expenditure (OpEx): Electricity is the largest operating expense, accounting for 40 - 50% of total OpEx. With industrial power tariffs of INR 6 - 8 per kWh and a PUE of 1.5, a 10 MW facility consumes about 131 GWh annually, resulting in electricity costs of roughly INR 79 - 105 crore per year. Other major operating costs include:

• Maintenance and equipment replacement (around 2% of CapEx annually)
• 24×7 staffing for operations, engineering, and security
• Diesel fuel for backup generators during outages and testing
• Water and sewage charges, especially for water-cooled facilities
• Network connectivity and bandwidth charges

Revenue outlook: To deliver attractive returns, a 30 MW colocation facility requires strong recurring revenue. In premium markets such as Mumbai, rack pricing typically ranges from INR 35,000 - 60,000 per rack per month, depending on power density and redundancy level.

Power availability: India's most critical infrastructure challenge

Reliable power is the foundation of a data center, and in India it remains one of the biggest operational challenges. While generation capacity has expanded, distribution infrastructure is still uneven, making backup power systems essential for Tier III and Tier IV facilities.

The power grid

Power reliability varies significantly across India. Even major cities can experience outages lasting from seconds to several hours. Maharashtra, Karnataka, and Telangana generally have stronger grid infrastructure, while states such as Uttar Pradesh and Bihar face greater reliability challenges.

Power procurement options

Data center operators can source power through multiple models:

• DISCOM supply: Common for facilities below 5 MW, subject to local tariffs and grid reliability.
• Open Access procurement: Facilities above about 1 MW can buy power directly from generators or exchanges, reducing costs and enabling renewable energy sourcing through long-term PPAs.
• Captive power: Large campuses (20 MW+) often use dedicated substations or on-site generation for greater reliability.
• Renewable energy integration: Solar, wind, and battery storage are becoming increasingly attractive due to lower costs and sustainability goals. Renewable power under long-term PPAs can cost INR 2-3 per kWh, compared with INR 6-8 per kWh for industrial grid power.

Backup power design

Redundant backup systems are mandatory for high-availability data centers:

• Tier III: Requires N+1 generator redundancy.
• Tier IV: Requires 2N independent power paths.

A standard design includes:

• UPS systems with 10-15 minutes of battery backup
• Generators capable of supporting the full IT and cooling load
• Automatic Transfer Switches (ATS) with sub-second switching
• Fuel storage for 48 - 72 hours, with hyperscale facilities often maintaining up to 7 days of reserve

Cooling and energy efficiency

Cooling is one of the biggest technical challenges for Indian data centers due to the country's high temperatures and humidity. Unlike cooler regions, free cooling is practical only in limited locations and seasons.

The PUE benchmark

Power Usage Effectiveness (PUE) measures how efficiently a data center uses energy. A PUE of 1.0 is ideal, 1.2 is world-class, and 1.5 is considered good for tropical climates. Leading Indian facilities achieve 1.4-1.5, while older facilities often operate above 1.8, consuming significantly more energy for cooling and power distribution. Improving PUE from 1.8 to 1.5 in a 10 MW facility can save around 26 GWh of electricity annually.

Cooling technologies

• Traditional air cooling: The most common solution for standard rack densities. Cooler cities like Bengaluru and Pune benefit from seasonal economizer modes, while humid cities such as Mumbai and Chennai see limited gains.
• Adiabatic cooling: Suitable for dry regions but increases water consumption, making it less attractive in water-scarce areas.
• Liquid cooling: Increasingly essential for AI and GPU workloads with rack densities above 30-50 kW. It transfers heat more efficiently than air and can reduce total data center power consumption by 10-15%.
• Hot aisle/cold aisle containment: A standard best practice that prevents hot and cold air mixing, improves cooling efficiency, and lowers chiller energy consumption.

Environmental considerations specific to India

Sustainability is becoming a key operational and regulatory requirement for Indian data centers, with water use and energy consumption emerging as the biggest challenges.

Water management

Traditional cooling systems consume significant amounts of water. A 1 MW data center can use around 26 million liters annually, while a 100 MW facility may require about 2 m³ of water per day for cooling. As India's data center capacity expands, water availability is becoming a critical concern, especially in water-stressed regions. Developers should minimize freshwater use by:

• Using closed-loop cooling systems that recycle water
• Sourcing treated wastewater from municipal treatment plants
• Installing on-site water recycling and reuse systems
• Avoiding groundwater-dependent or water-stressed locations

Some states, including Andhra Pradesh, are promoting seawater cooling and incentivizing treated wastewater use to improve sustainability.

Carbon and renewable energy

India's net-zero targets for 2070 and renewable energy goals are increasing pressure on data centers to improve sustainability. The Bureau of Energy Efficiency (BEE) sets energy efficiency standards that influence cooling systems, UPS efficiency, and building design.

Operators should adopt renewable energy PPAs, pursue green building certifications such as IGBC or LEED, and monitor energy and water usage through transparent sustainability reporting. These measures not only improve efficiency but also help meet evolving regulatory and investor expectations.

Physical and digital security

Data centers in India must meet both international security standards and local regulatory requirements to protect critical infrastructure and customer data.

Physical security

Modern data centers use a multi-layered security approach:

• Perimeter security: Anti-climb fencing, vehicle barriers, and CCTV with at least 90 days of recording
• Building security: Controlled entry points, mantraps, 24×7 security personnel, and escorted visitor access
• Data hall security: Biometric and card-based access with detailed logging, plus secure cages or vaults for colocation customers
• Rack security: Individually locked racks with access limited to authorized personnel

Fire protection relies on clean-agent suppression systems (such as FM-200, Novec 1230, or inert gas) and VESDA early-warning detection, avoiding water-based systems in IT areas.

Digital security and compliance

ISO/IEC 27001 certification is effectively essential for serving enterprise and government customers. Data center operators must also comply with CERT-In requirements, including incident response plans, vulnerability assessments, penetration testing, and log retention.

Leading operators often obtain additional certifications such as SOC 2 Type II, TIA-942, Uptime Institute Tier, or EN 50600 to demonstrate security and infrastructure resilience.

Core network security measures include firewalls, IDS/IPS, DDoS protection, SIEM platforms for threat monitoring, and network segmentation to limit the impact of cyberattacks.

Under the IT Act, operators are required to maintain adequate security practices, with failures that cause wrongful loss or gain potentially attracting penalties under Section 43A.

Scalability: building for the long term

A data center should be designed for future growth. With infrastructure lasting 15-25 years and AI driving higher power densities, scalability must be built into the initial design.

Modular architecture

Modular construction allows operators to expand capacity as demand grows, reducing initial CapEx by 20-25% and shortening deployment timelines. Facilities are typically built with future infrastructure planned, while power, cooling, and IT systems are added in 1-2 MW phases without disrupting operations.

Power density planning

Modern data centers must support evolving workloads. New facilities should be designed for high-density racks (30-100+ kW), flexible power distribution, liquid cooling readiness, and stronger floor loading to accommodate future AI infrastructure.

Land and expansion

For facilities above 5-10 MW, securing adjacent land for future expansion is a major strategic advantage. India's leading data center hubs are increasingly being developed as 100-500 MW multi-phase campuses.

Interconnection

Carrier-neutral connectivity with a Meet-Me Room (MMR) and access to multiple network and cloud providers increases flexibility and long-term commercial value.

From planning to operations

A typical greenfield data center in India follows this timeline:

• Market study: 3-6 months
• Site acquisition and due diligence: 6-12 months
• Government approvals and incentives: Parallel with site selection
• Design and permits: 12–18 months
• Construction: 18-24 months
• Certification and customer onboarding: 3-6 months

A full greenfield project usually takes 3-4 years from concept to operations, while modular development can reduce the first phase to 18-24 months. India's data center industry is a long-term infrastructure opportunity. Success depends on careful planning, regulatory compliance, and designing facilities that can scale with future demand.
