STT GDC Bengaluru 2 is 4 MW — and identical cards at exactly 4 MW appear in four cities: Mumbai 1, Bengaluru 2, Hyderabad 1 and Ahmedabad 1. That repetition is the most informative thing in the entire STT estate, because it shows how the company enters a city. The same 4 MW building is 3% of the Mumbai portfolio, 17% of Bengaluru, 67% of Hyderabad and 100% of Ahmedabad. One module, four roles — and it is 17.4% of the 23 MW Bengaluru headline. No stage, rack count or PUE is published.

2Four cities, one module
A capacity that repeats to the decimal across four cities is a design decision, not a coincidence.
| City | The card | Portfolio it sits in | Module share |
|---|---|---|---|
| Mumbai | Mumbai 1 | 133 MW | 3.0% |
| Bengaluru | Bengaluru 2 | 23 MW | 17.4% |
| Hyderabad | Hyderabad 1 | 6 MW | 67% |
| Ahmedabad | Ahmedabad 1 | 4 MW | 100% |
| Jaipur | Jaipur 1 | 6 MW separately | 6 MW, not 4 |
Four identical buildings is a template. It says STT can enter a secondary city with a known design, a known cost and a known delivery time, roughly the way a retail chain opens a standard store.
It also explains the Ahmedabad figure: the company’s entire Ahmedabad presence is one 4 MW module, and it is one of only two STT records that count in this registry’s total at all.
3What a standard module tells you
Module sizes are the most useful thing an operator reveals without meaning to, because they predict the next building.
| Module | Where it appears | What it is for |
|---|---|---|
| 0.6 MW | Bengaluru 1, Delhi 1 at 0.9 | legacy suites and connectivity anchors |
| 4 MW | Mumbai, Bengaluru, Hyderabad, Ahmedabad | the city-entry module |
| 9 to 15 MW | Pune 1, 2 and 3 | the secondary-city workhorse |
| 18 to 24 MW | Pune 4 and 5, Bengaluru 3 | the expansion module |
| 49 to 60.5 MW | Navi Mumbai 2 and 3, Palava 4 and 5 | the hyperscale module |
Five distinct sizes across the estate, and each one has a job. That is a mature platform: it can drop a 4 MW presence into a tier-two city, a 15 MW hall into a secondary market and a 60 MW building into a hyperscale campus, using designs it has already built.
For a vendor selling into this market, that is the single most actionable finding in the STT set. A standard module means standard equipment schedules — which means procurement lists that repeat, and a predictable sales cycle per city entry.
Four cities, one 4 MW design. Anyone supplying racks, cooling or electrical gear to STT is selling into a repeatable specification rather than a bespoke build.
That is worth more than knowing the capacity of any single building.
4Where this one sits
Bengaluru 2 is the smallest of the three Bengaluru cards behind Bengaluru 3 and ahead of Bengaluru 1.
| Building | MW | Share | Role |
|---|---|---|---|
| Bengaluru 1 | 0.6 | 2.6% | legacy suite |
| Bengaluru 2 | 4 | 17.4% | the city-entry module |
| Bengaluru 3 | 18 | 78.3% | the workhorse |
| Total | 22.6 | — | against a 23 MW headline |
Seventeen per cent of a portfolio in a standard 4 MW building is a sensible structure: it gives the city a presence at low capital cost and leaves the large hall to carry the tenants that need scale.
What is missing is the same thing missing everywhere in this file — a rack count and a design density. A 4 MW module built to 5 kW a rack is a different product from one built to 12 kW, and the difference decides which customers can be served from it.

6Limits and open questions
- Identical capacity is not proof of an identical design. Four 4 MW cards could be four different buildings.
- No stage on any of the four cards.
- No racks, floor area or PUE anywhere in the set.
- Basis unstated. The Bengaluru headline is IT load; the individual cards do not repeat the qualifier.
- Single source for all four capacities.
- What would close it. Confirmation of a shared design. That one sentence would let a supplier plan against a repeatable specification.
