Reconciliation — India’s counted capacity, rebuiltGridvik registry · 242 source records · 130 counted · Operating 778.69 MW · Building 499.00 MW · Pipeline 2,236.00 MW

Every published Indian data-centre capacity number is a sum of unlike things. Gridvik’s own registry was no exception: 2,420.37 MW across 86 records, in which an operating 0.3 MW exchange building and a 512 MW incentive approval carried equal weight, and in which gross facility power was added to IT load. This document rebuilds that number from the 242 source records using four rules, each of which can be checked against the audit file published beside it. The result is not one figure. It is three: 778.69 MW operating, 499.00 MW under construction, and 2,236.00 MW announced, approved or unverified. The old headline was larger than the first two combined and smaller than the third. It described no single thing, which is why it could not survive a diligence call.

1At a glance

2One number, four different things

Two records are enough to show why the old number could not be defended. PRJ-060, the AM AI Factory at Visakhapatnam, contributed 512 MW — 21% of the entire total — on an approved incentive application with unverified construction. And five AirTrunk facilities contributed 601 MW — another 25% — with a stage the source register itself records as unverified.

Put differently, 46% of the old headline came from records that are not operating buildings. That does not make them worthless. An approved 512 MW AI factory is one of the most important facts in the registry. It simply is not capacity, and adding it to a 0.3 MW telephone-exchange building produces a number that means nothing.

3The four rules

Every decision in the audit file follows one of four rules. Each is stated so that a reader can disagree with it, and if they do, recalculate in minutes from the published CSV.

Rule 2 is the one that changed the most numbers, and it cut in both directions. It removed 72 MW from PDG Chennai, a campus claim with no building breakdown, and it added 171 MW of STT GDC Palava buildings that had previously been marked non-additive along with their parent campus — so the capacity had vanished from the total entirely.

That second case was a systematic error. Forty-five container records and their children were all flagged non-additive, which meant a campus could be recorded, described and dated in the file while contributing nothing to the sum. West Bengal was the clearest casualty: four operators, about 95 MW published, and 1.08 MW counted.

4The reconciled ladder

The single most useful number in this registry is 778.69 MW — verified operating capacity across 49 named buildings. It is a floor, not a census: it counts only capacity that carries a building-level record, so a facility with no record of its own contributes nothing even if it is running.

602.69 MW of that 778.69 is on an IT-load basis and the rest is published facility power or an unstated basis. That split matters more than the total. A wholesale customer buys IT load; a utility sells facility power. Mixing them is how a 62 MW facility becomes a 62 MW IT claim.

1,456 MW of the reconciled total is facility power or an unresolved basis. Converting it to IT load requires a PUE assumption per record, and this file does not make one globally — the declared PUEs range from 1.40 to 1.70, so a blanket 1.5 would misstate individual buildings by up to 13%. The basis is flagged per record in the audit file instead.

5Where the 2,420.37 MW went

The additions are the part that would never have been found by inspection. When a campus row and its building rows are all marked non-additive, nothing in any report looks wrong — the records are present, dated and sourced. They simply never enter a total.

Sify Rabale is the case worth remembering. It is the operator’s largest campus, a DGX-Ready certified campus by its own account, and it publishes 96.94 MW built across five towers. Under the previous method it contributed nothing to the national figure, because the campus row and the tower rows were all marked non-additive. The reconciliation recovers 43.3 MW — Tower 5 only, because the other four towers have no separate records. Even the corrected figure is a floor.

6Operators, ranked by operating capacity

The largest operating data-centre operator in India, on this registry’s evidence, is NTT Global Data Centers at 273.2 MW. That is a correction to an earlier claim on the Yotta pages, which described Yotta as the largest additive operator at 236 MW — a figure produced by adding its 1 MW and 2 MW facilities to its 60 and 120 MW ones without separating stage.

On operating capacity the order is NTT 273.2, Yotta 145.8, Sify 125.1. On pipeline the order reverses: STT GDC 329.2 MW announced against 35.0 MW operating, and CtrlS 193.2 against 33.1. Those ratios are the most interesting numbers on this page.

Nxtra by Airtel is the other outlier: 38.0 MW operating against 238.2 MW in pipeline. Eighteen Nxtra facility records are marked stage-unverified in the source register, which is why they sit in the pipeline tier despite the facilities being real and in service. That is a data-quality limit of this file, not a market statement, and it is the largest single item in the review queue below.

7States, reconciled

Three states change character under reconciliation. Telangana’s 341.3 MW becomes 19.9 MW operating, because 283.4 MW of it is AirTrunk HYD1 and CtrlS Chandanvelly at unverified or planned stage. Andhra Pradesh’s 512.0 MW becomes 512.0 MW of pipeline and nothing operating. And Maharashtra’s 786.4 MW becomes 328.7 MW operating with 820.2 MW still to be built.

Those are not declines. They are the same facts described accurately. A state with 328.7 MW operating and 820.2 MW under construction or announced is a far more useful object than a state with “786.4 MW”.

8What is set aside

The 1 GW-scale records deserve a note because they are the most quoted numbers in Indian data-centre press. Eleven records in this file declare 1 GW or more, 17,300 MW between them — Reliance Jamnagar at 3 GW, AirTrunk Raigad at 3 GW, Tata Power’s 2.8 GW opportunity pipeline, Reliance Bhogapuram at 1.5 GW, and eight separate 1 GW programmes from Google, Adani, AdaniConneX, TCS, Digital Connexion and High Density Data Centre.

Setting them aside is not scepticism about the companies. It is the only way to keep the words “megawatts” and “buildings” in the same sentence. A reader who wants the announcement total has it: 22,200.8 MW of declared ceilings, which is the honest denominator for a media figure like “India has announced 20 GW”.

9What is still open, and what changes

This document fixes the structure. It does not fix the source data, and four things remain open.

The Nxtra and AirTrunk items are worth more than everything else combined — 839 MW sitting in the pipeline tier for want of a status confirmation, against a 778.69 MW operating total. Confirming them would more than double the defensible figure. Not confirming them is why the operating number is a floor.

Three claims elsewhere in this registry are now known to be wrong and are corrected here:
