STT GDC Palava 1 is 50 MW — the first of three named buildings on a 400 MW campus at Palava, on 46 acres. Fifty megawatts is one megawatt more than Navi Mumbai 2, the largest building the company operates today. The campus has a groundbreaking, a land parcel and a stated design capacity. This building has a card. No commissioning date, basis, rack count or PUE is published, so the most important new building in the Mumbai market is currently a number on a page.

The comparison is exact and it is the reason Palava matters to the Mumbai market.
| Measure | Palava 1 | Navi Mumbai 2 | Reads as |
|---|---|---|---|
| Capacity | 50 MW | 49 MW | the new phase beats the old flagship by 1 MW |
| Buildings compared | 1 of 3 named | the largest of six | a phase against a flagship |
| Campus behind it | 400 MW design | no further expansion | the campus is 3× the portfolio |
| Land | 46 acres shared | established site | room to keep building |
| Dates | none | none | neither building is dated |
A 50 MW first phase is not a test building. It is a full-scale hall, and it will be the largest single data centre building in this registry when it lands — ahead of Navi Mumbai 2 at 49 and the two 60.5 MW Palava buildings that follow.
The implication for anyone forecasting Mumbai supply: the growth is not incremental. It arrives in 50 and 60 MW units, on a site with 46 acres and a claimed 3 GW of available power from the township developer.
3171 of 400
Three buildings are named on a campus that is designed for 400 MW. That leaves a large amount of the campus unaccounted for in public.
| Item | Figure | Source |
|---|---|---|
| Campus design capacity | 400 MW | operator campus page, tracked as PRJ-061 |
| Groundbreaking | March 2026 | first phase reported at 50 MW |
| Land | 46 acres | inside a planned industrial park |
| Named buildings | 171 MW across three cards | this record, PRJ-117 and PRJ-118 |
| Unnamed capacity | 229 MW | no building names, no dates |
| Named share of the campus | 43% | just under half |
Forty-three per cent of the campus has a building name. The rest is design capacity with no building behind it, which is normal at groundbreaking and is exactly where the registry should stop rather than extrapolate.
What makes Palava different from the announced parks on other pages is that there is a physical event behind it — a groundbreaking in March 2026 — and a developer with a power claim. That moves it from tier D to tier C in this registry. It does not make it supply.

5Limits and open questions
- No commissioning date. The card gives a capacity and nothing else.
- No basis, racks, floor area or PUE. Density cannot be computed.
- Campus power is a developer claim, not a sanctioned allocation published by a utility.
- Stage unverified. The campus has a groundbreaking; this specific building may not have started.
- 229 MW of the campus is unnamed and is not counted anywhere in this registry.
- What would close it. A delivery date and a basis. Two facts and this becomes the most important record in the Mumbai pipeline.
