AirTrunk HYD1 — Chandanvelly, HyderabadAirTrunk, via Lumina CloudInfra · Chandanvelly, Ranga Reddy district, Telangana · 243 MW facility capacity · 13.3 ha · 440/220 kV substation

AirTrunk HYD1 at Chandanvelly in Hyderabad is 243 MW of facility capacity on 13.3 hectares with about 179,000 square metres of built-up area, a 440/220 kV substation and a declared design PUE below 1.4. It is the largest single site in this registry. Two hundred and forty-three megawatts is 10% of the entire counted national total of 2,420.4 MW, and it is nearly four times the largest building NTT operates in India. Four hundred and forty kilovolts is also the highest connection published anywhere in this file, and it is the detail that makes 243 MW plausible at all. At that voltage a single site can draw what a small industrial town draws. The caveat is the same as every other AirTrunk card: nobody has published whether it is built. And the built-up figure carries a transcription problem in the source that this registry flags rather than corrects.

1At a glance

2243 MW is a tenth of the registry

No single building in this file comes close. The comparison is worth setting out because it shows how far the Indian market’s individual assets are from its announcements.

Two hundred and forty-three megawatts in one building is a genuinely different category of asset from anything NTT operates in India. NTT’s largest single building is 62 MW, and its largest campus at Airoli is 336 MW across four planned buildings.

Which means the Indian market, as this registry records it, has a long tail of 10 to 60 MW buildings and a handful of very large announced sites — and the very large ones are almost all cards rather than buildings.

The honest framing for anyone using this: AirTrunk’s five Indian sites total 601 MW. NTT’s 32 counted records total 181 MW. The second number is made of buildings. The first is made of location pages.

3440/220 kV, the highest in the file

The substation is the number that makes the capacity credible, and it is the only figure on this card that could not have been written by a marketing department.

A 440/220 kV substation with a 220 kV dual connection is what a site needs if it intends to draw a quarter of a gigawatt. At 7.4 MW an acre over 33 acres, with 1.93 million square feet of building, the electrical design is the gating item and it is published at the right level.

It is also the slowest thing on any Indian schedule. The NTT example in this registry is instructive: NAV1 in Mahape energised on a temporary 22 kV line and moved to 220 kV after commissioning, because waiting for the high-voltage connection would have delayed the building. A site publishing a 440/220 kV substation is describing a facility that expects to wait, or to build in phases behind a smaller feed.

4Chandanvelly, and the CtrlS park next door

Chandanvelly is a village in Ranga Reddy district, south-west of Hyderabad, and it has become one of the most concentrated data centre locations in southern India.

Nine hundred and forty-three megawatts published in one village against 341.3 MW counted across the whole of Telangana in this registry. The ratio is the same one that appears everywhere in this file: announcements run at roughly three times the countable stock.

The registry’s note against this record is specific: Chandanvelly also hosts the CtrlS hyperscale park, which is a separate operator on a separate parcel, and no parcel-level relationship has been established. Shared geography is not shared infrastructure, although at 400 kV it very nearly is.

The strategic point is that Hyderabad is where the largest single-site bets are being placed. Telangana’s counted capacity of 341.3 MW is already the second-largest state total in this registry after Maharashtra, and the announced pipeline in one village exceeds the entire state’s countable stock by nearly a factor of three.

One data-quality note, stated plainly. The built-up area on the operator card prints as 179,00m² — a digit short. This registry transcribes it as 179,000 square metres, which is the only reading consistent with the site’s 13.3 hectares and the 243 MW capacity, and flags it as a source typo rather than a corrected fact. The derived figure of about 7,929 square feet per megawatt depends on that reading.

6Limits and open questions

• Stage is unverified. No operating or construction status is published on the operator card.
• 243 MW is facility capacity, at least — not IT load. At a 1.4 ratio the IT inside would be about 174 MW, which is derived and not published.
• The built-up figure prints as “179,00m²” in the source and is transcribed as 179,000 sq m with the typo flagged. The 7,929 sq ft per megawatt ratio depends on it.
• Design PUE below 1.4 is a specification, not an operating measurement.
• No parcel-level link to the CtrlS Chandanvelly park in the same village.
• No rack count, tenant list or occupancy.
• What would close it. A substation energisation date. Everything else on this page is downstream of it.
