STT GDC states about 12 MW for Delhi, and its three cards read 0.9, 1 and 10 MW — a sum of 11.9, which rounds to 12. The arithmetic is fine. What is not fine is the state. This registry holds exactly four data centre records for Delhi, and all four are STT’s. All four are flagged non-additive. So the National Capital Territory counts zero megawatts. Twelve megawatts is a small portfolio in a city of twenty million people, and it is also the entire data centre record of India’s capital.

2Four records, zero counted
Delhi is the cleanest example of an additivity rule turning a market into a blank.
| Record | MW | Flag | Counted |
|---|---|---|---|
| STT Delhi portfolio | 12 | non-additive | 0 |
| STT Delhi 1 | 0.9 | non-additive | 0 |
| STT Delhi 2 | 1 | non-additive | 0 |
| STT Delhi 3 | 10 | non-additive | 0 |
| Delhi total | 11.9 published | — | 0 MW |
There is no competing record to compare against. The capital of India has one operator with a published presence and this registry reports it as zero megawatts, because the parent aggregate and its children are all excluded by the same rule.
Anyone reading a state-by-state table from this file would conclude Delhi has no data centre capacity at all. That is materially wrong, and it is the kind of error that discredits an entire dataset the first time a buyer checks it.
West Bengal is the worst ratio. Delhi is the cleanest proof: a state whose entire record set is one operator, published, and counted at nothing.
The fix is the same one: count the facility, hold the aggregate as a ceiling.
3Twelve megawatts in a capital city
Delhi is a genuine anomaly in Indian data centres: a huge enterprise market with almost no capacity inside it.
| Reason | Consequence |
|---|---|
| Land and power costs | very high per megawatt inside the territory |
| Pollution and construction restrictions | long approval cycles and winter bans |
| Water availability | cooling constraints in a water-stressed city |
| Where the capacity went instead | Noida and Greater Noida, in Uttar Pradesh, 326 MW counted |
| What Delhi retains | small latency-sensitive suites near the exchange and government district |
That explains the shape of this portfolio perfectly. A 10 MW building and two suites under a megawatt is what a market looks like when the demand is real and the land is impossible.
The right way to read Delhi is therefore not as a market in its own right but as the centre of a metropolitan market whose capacity sits across the state line. Noida and Greater Noida count 326 MW; Delhi counts 11.9 published and 0 counted.
4The second narrative
Beyond the headline and the cards, the Delhi page carries a third set of numbers in prose.
| Source | Figure | What it might describe |
|---|---|---|
| City headline | about 12 MW | the whole Delhi footprint |
| The three cards | 11.9 MW | the same, itemised and rounded |
| Narrative in prose | 6 MW, scalable to 9.5 MW of IT | one facility, described in a separate paragraph |
The 6 MW to 9.5 MW pair is probably Delhi 3, described elsewhere on the site as a 6 MW facility with room to reach 9.5 MW of IT. If so the card value of 10 MW sits between the two narrative figures — closer to the scalability ceiling than the current capacity.
This registry keeps 10 MW as the card value and records the narrative separately, because cards are the layer that reconciles. But the three-way divergence is worth naming: a single city page carries three different capacities for the same two buildings, and only one of them is in the portfolio total.

6Limits and open questions
- State counts zero. All four Delhi records are excluded by the additivity rule.
- Three capacities for one portfolio — 12 in the headline, 11.9 in cards, 6 and 9.5 in prose.
- Basis unresolved. No Delhi figure is labelled IT or gross.
- No stage, racks, floor area or PUE for any Delhi building.
- Delhi and Noida are different states and must never be summed into a single "Delhi NCR" number without saying so.
- What would close it. A clarification of the 6, 9.5 and 10 MW relationship.
