NTT Noida 2 Building A opened in January 2024 in Tech Zone IV, Greater Noida, with 22.4 MW of critical IT load across 300,000 square feet — the first of two buildings on a six-acre campus planned for 52.8 MW. It was the first data centre campus in India to incorporate seismic dampers, and it came with liquid immersion and direct contact liquid cooling as standard NTT issue. The most valuable number on this page is not the 22.4. It is 13,393 — square feet of building per megawatt of IT. Set that against NTT’s other documented buildings and a pattern appears: 13,333 at NAV1A, 13,455 at Vikhroli, 12,917 at the 2011 Noida retrofit. Four buildings, three cities, thirteen years, all within 4% of 13,300 square feet per megawatt. That is a design constant, and it is what lets this registry estimate a building’s floor area — or its capacity — from the other half of the pair.

2The 13,300 standard
Indian data centre capacity is usually published as a single number, which makes nothing comparable. NTT publishes two numbers for this building, and the second one is a Rosetta stone.
| Building | IT load | Floor | sq ft per MW |
|---|---|---|---|
| Noida 1, 2011 retrofit | 1.5 MW | about 19,375 sq ft | 12,917 |
| NAV1A, 2022 | 30 MW | 400,000 sq ft | 13,333 |
| Noida 2 Building A, 2024 | 22.4 MW | 300,000 sq ft | 13,393 |
| Vikhroli, 2012 | 2.4 MW | about 32,292 sq ft | 13,455 |
| Spread across all four | — | — | 4.2% |
| Working constant | — | — | 13,300 sq ft per MW |
Four per cent across thirteen years is not a coincidence and it is not a rounding artefact. It is a building type: a standard hall module with a fixed relationship between floor plate, electrical room, cooling plant and rentable load.
Which gives this registry a working tool. Multiply any NTT IT figure by 13,300 and you have a floor area estimate. Divide any NTT floor area by 13,300 and you have a capacity estimate. Neither is a published figure, and both are labelled as estimates wherever they appear.
NAV1B is published at 30.4 MW. The standard predicts about 405,800 sq ft. A directory listing gives it 577,576 sq ft — 42% above the standard. Either the building is a different type or the listing is wrong. That question is open on record PRJ-160.
Noida 2 Building B is also published at 30.4 MW. The standard predicts the same 405,800 sq ft. No floor area has ever been published for it.
374.7 kW per thousand square feet
The same two figures expressed the way a facilities engineer would use them: how much IT load a square foot of building carries.
| Measure | Noida 2 Building A | NAV1A, for comparison |
|---|---|---|
| Critical IT load | 22.4 MW | 30 MW |
| Building area | 300,000 sq ft | 400,000 sq ft |
| IT kW per 1,000 sq ft | 74.7 kW | 75.0 kW |
| Facility kW per 1,000 sq ft at 1.5 | 112 kW | 112.5 kW |
| Floor per MW of IT | 13,393 sq ft | 13,333 sq ft |
| Difference | 0.4% | baseline |
Two buildings, two campuses, two years apart, and the density per square foot of building is identical to within half a percent. This is not how the Indian market describes capacity anywhere else — and it is exactly the kind of check that catches an inflated figure.
It also puts a ceiling on the AI narrative for this building. At 74.7 kW of IT per 1,000 square feet, a 300,000 square foot floor carries 22.4 MW no matter how the cabinets are arranged. Denser cabinets do not create capacity; they consume less of the floor to use the same capacity.
The number that would matter for AI is not on this page. It is kW per cabinet, and NTT has not published a rack count for Noida 2 Building A.
4First seismic dampers in India
NTT made a specific and checkable engineering claim at the launch: this was the first data centre campus in India to incorporate seismic dampers.
| Item | Detail |
|---|---|
| Seismic dampers | First data centre campus in India to use them, per the operator |
| Cooling | Liquid immersion cooling and direct contact liquid cooling available |
| Automation | Monitoring and optimisation of power and water resources |
| Connectivity | Carrier neutral, interconnected with NTT’s other Indian campuses |
| India footprint at launch | 268 MW across 18 facilities, over 3.1 million sq ft |
| Investment context | Part of an USD 11 billion commitment for 2022 to 2027 |
Seismic dampers are not marketing. Delhi NCR sits in a seismic zone where structural protection is a real engineering cost, and being first to install the equipment is a genuine differentiator with financial-services tenants who carry business continuity obligations.
The 268 MW and 18 facilities at launch are also worth holding onto, because they are NTT’s own total for India as of January 2024 and they sit against 181 MW of additive NTT records in this registry. The difference is the aggregate — campuses, planned phases and the 500 MW NAV2 announcement, none of which is a building.
That is the cleanest illustration of the registry’s central rule: an operator’s own 268 MW is a portfolio statement, and 181 MW is what can be pointed at.

6Limits and open questions
- 22.4 MW is critical IT load and is not comparable with NTT’s facility-load figures at Mumbai 8 and Mumbai 9.
- 33.6 MW of facility load is derived at the 1.5 house ratio and is not published for this building.
- The 13,300 sq ft per MW constant is four data points, not a specification. It is used only as a labelled estimate.
- The 19,375 sq ft used for Noida 1 converts from a metric server-space figure and is approximate.
- No rack count, no PUE, no occupancy, no tenant list.
- Seismic dampers are an operator claim with no certification number attached.
- What would close it. A rack count and a per-cabinet kW figure. Two lines, and neither is published.
