NCR 4 is the hyperscale building in Nxtra’s Noida cluster: 18 MW of IT power across 3,000 racks, or 6 kW a rack, with a declared PUE below 1.55. It carries 47% of the operator’s 38.5 MW Delhi NCR cluster while holding fewer cabinets than its two legacy Noida halls combined — which is the clearest illustration in this registry that rack count and capacity have stopped moving together. The operator does not name a sector for it; a directory places it at Sector 59 in Noida.
1At a glance
218 MW on 3,000 racks
The interesting fact about this building is not its size. It is what happens when you put it beside its siblings.
| Building | MW | Racks | kW a rack | Share of the three |
|---|---|---|---|---|
| NCR 4 | 18 | 3,000 | 6.0 | 69% |
| NCR 1 | 4.5 | 1,250 | 3.6 | 17% |
| NCR 2 | 3.5 | 1,500 | 2.3 | 13% |
| Total | 26 | 5,750 | 4.5 | 100% |
Read down the rack column and the cluster looks evenly spread. Read down the megawatt column and it is not: one building holds two thirds of the power in these three on just over half the cabinets. The average density of the cluster, 4.5 kW a rack, is the average of a modern building and two legacy ones and describes neither.
At 6 kW a rack this is a competent mid-density hall — better than the legacy buildings, well short of the 11.7 kW at Mahape and far short of what an AI tenancy needs. It sits in the middle of the Indian market’s range, which is where most capacity that is actually for sale in the NCR sits.
3The NCR cluster, four cards
Nxtra’s Delhi NCR cluster is its fifth largest, behind Mumbai, Pune, Chennai and Bengaluru, and it is the one where the operator’s capital is least visible.
| Cluster | Capacity | Share of the five | Growth signal |
|---|---|---|---|
| Mumbai | 71 MW | 28% | land acquisition focused here; two new AI halls at Mahape |
| Pune | 49.5 MW | 20% | four cards; a 110 MW campus announced in 2021 and never built |
| Chennai | 46 MW | 18% | AI campus development announced; cable hub |
| Bengaluru | 45.4 MW | 18% | four cards across Whitefield and Hoskote |
| Delhi NCR | 38.5 MW | 15% | no expansion programme in the public record |
| Five clusters combined | 250.4 MW | 100% | the rest sits in Hyderabad, Kolkata, Bhubaneswar and edge sites |
That table is the practical map of this account. 250.4 MW across five clusters is as much as the operator’s own national headline, before a single edge site, and the new AI campuses it has described publicly are in Mumbai, Chennai and Kolkata — not in Noida. The NCR is mature, profitable and not where the next 750 MW will be built.
There is one important counterweight. Noida is the closest large data centre market to Delhi’s government, financial and enterprise demand, and the NCR contains a substantial share of India’s enterprise colocation. Capital may not be pouring in, but demand does not move either.
4A naming problem worth knowing
This building appears under at least three names in the market, and one of them implies a facility the operator does not list.
| Source | Name | Note |
|---|---|---|
| Operator | NCR 4 | the only name the owner uses |
| Directory listing | NCR 4 (Noida hyperscale) | address given as Sector 59 |
| Separate directory record | Nxtra Noida III | described as a 450,000 square foot hyperscale building for 5,000 racks |
| The operator’s own site navigation | Noida 62 (NCR 1), Noida 81 (NCR 2), NCR 4 | no NCR 3 is listed anywhere |
The gap is the missing NCR 3. The operator lists three Noida facilities and numbers them 1, 2 and 4. Directories carry a fourth building called Noida III with 5,000 racks. Either NCR 4 is that building under a different label, or there is a facility that is not on the operator’s current page.
Gridvik does not resolve it. The registry keeps NCR 4 at 18 MW across 3,000 racks, which does not match the 5,000-rack description, and records the discrepancy rather than merging two buildings into one. Anyone sizing Nxtra’s Noida footprint should assume the published three cards understate it by one building.
Three published cards in Noida, 26 MW, and a fourth building in Manesar that the operator publishes on a separate page — now recorded as PRJ-084 at 12.5 MW. The cluster is 38.5 MW. The operator never totals it for you.
Gridvik publishes the number it can evidence and names the gap. That is the difference between a registry and a directory.
5Timeline
- Noida becomes one of Nxtra’s established markets alongside Mumbai, Pune, Bengaluru and Chennai, serving Delhi NCR enterprise demand
- The operator’s Noida page lists NCR 4 at 18 MW of IT power across 3,000 racks with a declared PUE below 1.55, alongside NCR 1 and NCR 2
- Directories carry a separate “Noida III” record describing a 450,000 square foot hyperscale building for 5,000 racks. No operator page lists an NCR 3
- No commissioning date, occupancy figure or tenant name for NCR 4 in the public record
