NTT's Mumbai Vikhroli data centre — VIK DC2 — carries 2.4 MW of critical IT load in 3,000 square metres of server space, with 6 MVA of total facility load. Built in 2012 on the Mehra Industrial Estate off LBS Marg, it is a direct-expansion-cooled, bottom-up-air building with dual feed and 3 to 6 kVA per cabinet. Six megavolt-amperes is not six megawatts: at a 0.9 power factor it is about 5.4 MW, which puts the facility-to-IT ratio at roughly 2.25 — a 1.48 hall's plant load and a half. And the stated 3 to 6 kVA per rack is the number that dates the building. On its own specification, 2.4 MW needs 400 to 800 cabinets. On the 17.2 kW being sold in Chandivali in July 2026, it needs 140.

2A 2012 building in a 2026 market
Every figure on this page is published by NTT. That is unusual and it is why the record can be built at all. What those figures describe is a building designed in a different era of the same industry.
2.4 MW was a respectable hall in 2012. It is now 3.9% of the single building NTT opened in the same city in 2023, and 1.5% of NTT Mumbai’s 161 counted megawatts.
| Measure | Vikhroli, 2012 | Mumbai 9, 2023 |
|---|---|---|
| Critical IT load | 2.4 MW | about 42 MW inside 62 MW facility |
| Cabinets | about 400 to 800 | 6,000 |
| Rack power | 3 to 6 kVA | up to 17.2 kW sold in 2026 |
| Cooling | direct expansion, bottom-up air | unspecified; supports 17.2 kW racks |
| Server space | 3,000 m² | not published |
| Facility-to-IT ratio | about 2.25 | about 1.48 |
None of this makes Vikhroli a bad asset. It makes it a specific asset: a workhorse hall for workloads that need 3 to 6 kW cabinets and a Mumbai address, at a ratio that no modern build would accept.
3What 6 MVA actually converts to
This is the most common error in Indian data centre reporting, and it is worth being blunt about it. A megavolt-ampere is apparent power. A megawatt is real power. The conversion needs a power factor, which nobody publishes.
| Assumption | Facility load in MW | Ratio to 2.4 MW IT | Comment |
|---|---|---|---|
| Naive, MVA treated as MW | 6.0 MW | 2.50 | what a careless comparison does |
| Power factor 0.9 | 5.4 MW | 2.25 | the working figure used on this page |
| Power factor 0.85 | 5.1 MW | 2.13 | typical for an older plant |
| 4 MVA per feed, dual feed | about 7.2 MW | 3.00 | if the 6 MVA is a per-path rating |
The registry uses 2.25 and flags it as an estimate. The spread matters commercially: at a 0.9 factor the annual power bill for 2.4 MW of IT is about Rs 30 crore at Rs 8 per kWh and 80% loading. At a 1.48 ratio the same load would cost about Rs 20 crore.
Ten crore rupees a year is the running cost of a five-year-old cooling design. It is invisible in any headline, because headlines quote the megawatts and never the ratio.
This is the kind of line a tenant can take into a renewal negotiation and an operator cannot argue with, because the operator published both halves of it.
4Half of this building is plant
Six MVA behind 2.4 MW is not an accident of engineering. It shows up in the floor plan, and the floor plan is published.
| Measure | Value | Basis |
|---|---|---|
| Server space | 3,000 m² | operator-stated |
| Gross building | about 64,580 sq ft | third-party listing |
| Server space as a share of gross | about 50% | 3,000 m² of about 6,000 m² |
| Cabinets at 5 kVA | about 480 | 2,400 kW divided by 5 |
| Cabinet floor allowance | about 6.25 m² | 3,000 m² divided by 480 |
| Cabinets at 17.2 kW | about 140 | for the same 2.4 MW of IT |
| Floor needed at 17.2 kW | about 875 m² | a third of the current server floor |
Half the building is plant and the other half is cabinets, at 6.25 square metres per cabinet. That is a generous modern allowance — density is not this building’s problem. Power is.
The 2.25 ratio is the price of a direct-expansion cooling design and a 2012 electrical layout. It is the reason NTT’s own newest halls are built at 1.48 and the reason this page can be written from public data at all.

6Limits and open questions
- 6 MVA is not 6 MW. The 2.25 ratio depends on a 0.9 power factor, which is an assumption. At 0.85 it is 2.13; at 3.00 if the figure is per feed.
- The 64,580 sq ft gross figure comes from a third-party listing, not the operator. The 50% server-space share is derived from it.
- Rack count is unpublished. The 400 to 800 range is inferred from the operator’s own 3 to 6 kVA specification.
- Built 2012 is from a directory listing. NTT does not date this facility on its own page.
- No PUE, no occupancy, no tenant list, no dated commissioning evidence.
- What would close it. A stated power factor and a rack count. Both are one line on a facility page.
