Yotta NM1 at Panvel is the largest single-building data centre in this registry by floor area: 820,000 square feet, 16 floors, capacity for more than 7,000 racks, 52 MW of IT load, a declared PUE below 1.5, IGBC Platinum, and Tier IV certification with the Uptime Institute’s Gold Certificate of Operational Sustainability. It has been published at 52, 50, 36 and 30.4 MW across six years. The park around it has been described as scalable to 160 MW, 250 MW, 1 GW and 2 GW. And on cost it is the outlier in the entire file: ₹1,000 crore invested for 52 MW is ₹19.2 crore per megawatt, a third of the ₹51 to ₹60 crore the rest of the market pays.

2Four capacities for one building
| Source | Date | Figure | Stated scope |
|---|---|---|---|
| Yotta portfolio page | 2026 | 52 MW | IT load, with 7,000 racks |
| DataCenterMap listing | 2026 | 52 MW | Fully built-out and live power, max 15 kW per rack |
| Launch release | 2020 | 50 MW | Power, with 7,200 racks |
| Yotta blog, Inside NM1 | Nov 2024 | 36 MW | IT power capacity, with 7,200 racks |
| The Hindu BusinessLine | Aug 2025 | 30.4 MW | “The entire facility has a capacity of” |
| This registry | — | 52 MW | The highest published value |
A 21.6 MW spread — from 30.4 to 52 — is the widest capacity disagreement in this file for a single operating building. The most likely explanation is phased fit-out: the 2020 launch delivered the building at roughly 50 MW of design power, the 2024 blog described what was fitted out at 36 MW, and the 2025 press description used an operating figure of 30.4 MW. The current page says 52 MW.
This registry counts 52 MW — the highest published value — because for a buyer the least favourable assumption is the safe one. If NM1 actually runs 30.4 MW, the registry overstates Indian capacity by 21.6 MW from this record alone.
Counting the highest published capacity risks overstatement. Counting the lowest risks understating, which flatters a market.
The registry rules that a facility’s nameplate or design capacity is what gets counted, because it is the figure a tenant can buy against and the figure the operator sells on. The operating figure is disclosed in the text beside it.
Where the two differ by 70%, both are published and neither is hidden. A reader who wants the conservative number has it on the same page.
3The cheapest megawatt in the registry
| Build | Cost and capacity | ₹ crore per MW | Year and basis |
|---|---|---|---|
| Yotta NM1 | ₹1,000 cr for 52 MW | 19.2 | 2020, own township land |
| Yotta NM1 at 30.4 MW | ₹1,000 cr | 32.9 | 2025 operating figure |
| NTT Bengaluru 4 | ₹2,400 cr for 67.2 MW | 35.7 | 2026, 8.5 acres |
| NTT NAV2 phase one | ₹5,500 cr for 107 MW | 51.4 | 2025, 54 acres |
| CapitaLand Chennai 01 | ₹1,940 cr for 34 MW | 57.1 | 2026, four acres |
| Colt DCS–RMZ | US$1.7bn for 250 MW | 60.1 | 2024, two cities |
| Market band | — | 51.4 to 60.1 | Excluding NM1 |
Yotta built its first data centre for a third of what the market pays now, and there are four reasons that are all visible in the record.
One: it was built in 2020, before AI-era cooling, before the land price run, and before the current power premium. Two: it sits inside the operator’s own 600-acre township, so the land was acquired at group cost rather than market. Three: it is a single 16-storey tower on 18 acres, which is the densest land use in the file at 2.9 MW per acre of its own plot. Four: the group is licensed to distribute power through an affiliated company, removing a utility margin.
Which makes ₹19.2 crore per megawatt a statement about 2018 to 2020 conditions and an integrated developer, not a benchmark anyone can hit today. New Delhi and Navi Mumbai land alone now runs to ₹9.9 crore per megawatt at AirTrunk’s Chandivali parcel.
NM1 is a 2020 Tier IV building with 7.4 kW racks. Every new build in this registry is specifying liquid cooling for racks at three to five times that density.
So the cheap megawatt is cheap partly because it is an older product. A tenant that needs 40 kW AI cabinets cannot use this capacity at that density, and a landlord cannot raise density on an existing raised-floor hall without rebuilding the cooling plant.
That is why the ₹19.2 crore figure should never be used as a comparable for new build economics — and why nobody should conclude that Indian data centres got 3× more expensive for no reason.
4Seven thousand racks at seven point four kilowatts
| Measure | Value | Comparison |
|---|---|---|
| Floor area | 820,000 sq ft | Largest single building in the file |
| Square feet per MW of IT | 15,769 | Against NTT’s 13,300 design standard |
| Watts per square foot | 63.4 | Above the Iron Mountain portfolio average of 42.2 |
| Racks | 7,000 | 7,200 quoted at launch |
| Kilowatts per rack | 7.4 | Against 17.2 for an AI cabinet in Chandivali |
| Maximum per rack | 15 kW | The ceiling a tenant can buy |
| Racks at 15 kW for 52 MW | 3,467 | Against 7,000 installed — the density gap |
| Floor load | 1,500 kg per sq m | Against L&T Mahape at 2,500 |
The density gap is the whole story of this building. It has 7,000 racks wired for a maximum of 15 kW each, but 52 MW of IT power spread across 7,000 racks is 7.4 kW average. To use its full ceiling at 15 kW per rack it would need 3,467 racks — half the physical footprint.
That is not a design failure. It is a 2020 design: colocation halls built for enterprise cabinets at 5 to 10 kW, in a market that now wants 40 kW liquid-cooled racks. Yotta and everyone else are now retrofitting or building new.
The 1,500 kg per sq m floor load is the physical limit on that retrofit. L&T’s new Mahape building is specified at 2,500 kg per sq m — 67% higher — precisely to carry denser racks and heavier cooling. You cannot raise a floor load on an operating building.
5The park: 160 MW, 250 MW, 1 GW or 2 GW
| Source | Date | Claim | Scope |
|---|---|---|---|
| Yotta portfolio page | 2026 | 1 GW | DC park scalable for hyperscale growth |
| Yotta press release | Feb 2026 | 2 GW | Navi Mumbai campus in the Blackwell Ultra release |
| Yotta data centre page | 2025 | 160 MW | Five buildings, 30,000 racks on the campus |
| Operator interview | 2025 | 250 MW | Campus plan referenced in market commentary |
| NM1 plus NM2 | 2025 | 112 MW | 52 MW plus a 60 MW NM2 shell |
| This registry | — | 52 MW | Only NM1 is counted |
Two gigawatts is twelve and a half times the 160 MW the same company publishes for its own five-building campus. Both figures are current and both are live on Yotta properties.
The 160 MW reading is the most concrete and the most credible: five interconnected buildings, 30,000 racks, 160 MW, on 18 acres of a 600-acre township. At 160 MW over roughly 18 acres that is 8.9 MW per acre, which sits comfortably in the range of the densest builds in this file.
A 2 GW campus would require land Yotta has not described — roughly 225 acres at its own density — which is possible inside a 600-acre township and is not the same as built capacity.
For a buyer the rule is simple: use the 160 MW, disclose the 1 GW and 2 GW, and count only the 52 MW that has a Tier IV certificate and 7,000 racks in it.
6Tier IV and the Blackwell Ultra deployment
NM1 is the most certified building in this registry, and that certification is the reason it has an AI story at all.
| Item | Detail | Significance |
|---|---|---|
| Uptime Tier IV design and facility | Certified | Fault tolerant: two independent distribution paths |
| Gold TCOS | Certified | Operational sustainability, not just design |
| IGBC Platinum | Certified | Green building rating |
| Downtime tolerance | 26.3 minutes per year | 99.995% availability |
| GPU deployment | 20,000 Nvidia Blackwell Ultra | Announced February 2026 |
| Where it lands | Part of the supercluster is on Navi Mumbai capacity | AI demand driving the retrofit |
| India live across Yotta | 84 MW | NM1 52, D1 30, G1 2 as of October 2026 |
Tier IV is a commercial asset in the Indian AI market. Fault-tolerant topology means concurrent maintenance of any component, which is what a sovereign or regulated AI deployment requires. NM1 is described as India’s only multi-tenant Tier IV facility with Gold operational certification, and that exclusivity is why it hosts high-value workloads despite being a 2020 building at 7.4 kW per rack.
The 20,000 Blackwell Ultra GPUs announced in February 2026 are deployed across Yotta’s estate, including Greater Noida. That matters for this record because it is the demand pulling 30.4 to 52 MW of existing capacity into AI service without new construction — a retrofit, not a build.
For anyone modelling Indian AI capacity: the country’s AI compute is currently running largely inside buildings designed for enterprise colocation, and the gap between that and the liquid-cooled campuses under construction is the next five years of this market.

8Limits and open questions
- Four published capacities for one building — 52, 50, 36 and 30.4 MW. The registry counts 52 MW and publishes all four.
- The park is published as 160 MW, 250 MW, 1 GW and 2 GW. None is counted; only NM1’s 52 MW enters a total.
- PUE below 1.5 is a design figure, not a measured annual value.
- ₹1,000 crore is the 2020 investment for NM1 and does not reflect what the same building would cost today.
- The 7,000-rack count assumes all racks are populated; 7.4 kW per rack is derived by division.
- 820,000 sq ft includes non-data-hall space, so 63.4 W per sq ft understates hall density.
- 52 MW is counted, the highest published figure, with the 30.4 MW operating description published beside it.
- What would close it. A current fit-out figure and a measured PUE.
