Why in News: On May 27, 2026, real-estate consultancy Cushman & Wakefield released its Global Data Center Market Comparison 2026 report, placing India 2nd in the Asia-Pacific (APAC) region by operational data centre capacity at 1.6 GW, with an additional 3.1 GW under construction or planned. Mumbai is projected to cross 1 GW operational capacity by end-2026 — becoming India’s first gigawatt-scale data centre hub.
Snapshot — India’s Data Centre Footprint
| Parameter | Value |
|---|---|
| Operational capacity | 1.6 GW (2nd in APAC) |
| Under construction / planned | 3.1 GW |
| Total pipeline | 4.7 GW |
| Vacancy rate (Q4 2025) | 12.9% |
| Population per MW | ~9.43 lakh (highly underpenetrated) |
| Mumbai (projected end-2026) | >1 GW operational |
The Six Key Indian Data Centre Markets
| Rank | City | Why |
|---|---|---|
| 1 | Mumbai | Subsea cable landings, financial hub, BKC + Navi Mumbai clusters |
| 2 | Chennai | Subsea cable landings (~7 active), Sriperumbudur ecosystem |
| 3 | Delhi NCR | Government + BFSI demand, Noida + Greater Noida hubs |
| 4 | Bengaluru | Tech demand, cloud hyperscalers, latency-sensitive workloads |
| 5 | Hyderabad | T-Hub + state policy push, hyperscaler campuses |
| 6 | Pune | Mumbai overflow, manufacturing demand |
APAC Ranking — Why India Climbed
| Rank | Country/Market | Operational (GW) |
|---|---|---|
| 1 | Mainland China (Beijing + Shanghai dominant) | ~5+ |
| 2 | India | 1.6 |
| 3 | Japan (Tokyo + Osaka) | ~1.4 |
| 4 | Australia (Sydney + Melbourne) | ~1.3 |
| 5 | Singapore | ~1.2 (moratorium-constrained) |
India overtook Japan, Australia and Singapore primarily because:
- Data localisation push — RBI 2018 payments data norms; DPDP Act 2023 nudging cross-border data flows toward domestic facilities.
- AI hyperscaler demand — GPU clusters require massive power + cooling.
- Hyperscaler entry — AWS, Microsoft Azure, Google Cloud, Oracle all committed multi-billion-dollar Indian investments through 2026–2030.
- State-level incentives — Maharashtra, Tamil Nadu, Telangana, UP have data-centre policies offering stamp-duty waivers and power tariff concessions.
- Submarine cable landings — India is the second-largest landing point in Asia after Singapore.
The AI Demand Wave
| Workload | Power Density |
|---|---|
| Traditional cloud (CPU) | ~5–10 kW per rack |
| AI training (GPU) | 40–80 kW per rack (some up to 100+ kW) |
This explains why new builds are GW-scale, not MW-scale. The NVIDIA H100/H200/Blackwell GPU cycle has driven Indian AI-ready capacity from ~50 MW (2023) to a projected ~1 GW by 2027.
Why India is Still Structurally Underpenetrated
| Metric | India | USA | Singapore |
|---|---|---|---|
| Population per MW of capacity | ~9.43 lakh | ~9,000 | ~33,000 |
| Internet users per MW | Very high | Low | Low |
Headroom: even doubling operational capacity to 3.2 GW would still leave India among the most under-served large economies on a per-capita basis. Some industry estimates project 8–10 GW by 2030.
Enabling Ecosystem
| Layer | Detail |
|---|---|
| Power | 24×7 reliability needed; renewable PPAs increasingly preferred (Microsoft, Google have signed multi-GW Indian solar PPAs) |
| Cooling | Tropical climate raises cooling cost; liquid cooling adoption accelerating for AI workloads |
| Connectivity | Submarine cables (e.g., 2Africa, SEA-ME-WE 6, MIST, IAX/IEX) landing in Mumbai, Chennai |
| Talent | Data Centre Operator skill council under NSDC; specialised cooling/electrical engineers in short supply |
| Policy | Data Centre Policy 2020 (draft) by MeitY; not yet finalised; state policies have moved faster |
| PLI link | IT Hardware PLI 2.0 (2023) supports server manufacturing in India |
Strategic Significance
- Digital sovereignty — domestic AI training and inference reduces dependence on foreign clouds.
- AI compute as critical infrastructure — India needs sovereign GPU pools for public-sector LLM training (akin to IndiaAI Mission, ₹10,372 crore, March 2024 Cabinet approval).
- Energy nexus — DC growth and renewable-energy capacity must scale in tandem; risk of fossil-heavy DC growth in coal-dependent states.
- Geopolitics — friend-shoring of data and compute away from China/Singapore favours India.
Risks and Watchpoints
- Power grid stress — AI clusters concentrated in Mumbai/Hyderabad strain regional grids.
- Water for cooling — major issue in Chennai (recurring shortages).
- Cross-border data flow rules — DPDP Act 2023 schema rules still pending; uncertainty deters some hyperscaler deployments.
- Cyber security — data-centre concentration creates single-point-of-failure risk; CERT-In’s mandate has expanded.
Way Forward
- Finalise National Data Centre Policy with green-DC standards, transparent cross-border data rules.
- Renewable PPA mandates for DCs above a capacity threshold.
- Sovereign GPU capacity under IndiaAI mission for public-good AI training.
- Tier 2/3 city DCs — Lucknow, Visakhapatnam, Bhubaneswar — to ease grid concentration.
- Skill mission — Data Centre Operator skill council to scale annual throughput.
