Bangalore 01 is Sify’s Electronic City facility, operational since 2006, with 600 racks, TIA-942-B Rated 3 certification and a lease that runs to Q1 2038. It is published at 4.82 MW on the current portfolio card, 7.6 MW on the portfolio page and in the 2025 integrated report, 4 MW in the 2024 annual report and 2.3 MW in a 2022 factsheet. Four figures, one building, and 5.3 MW between the highest and the lowest. The interesting part is not the disagreement. It is what the sequence shows: this building has more than doubled the power it delivers without adding a single rack, from 3.8 kW a cabinet to 8.0. At 4.82 MW Sify’s two Bengaluru sites together are 13% of Karnataka’s 90.72 MW counted capacity.

2Four capacities for one 600-rack building
| Figure | Source and date | MW | Scope and reading |
|---|---|---|---|
| Portfolio page | Sify Infinit Spaces and 2025 report | 7.6 | Stated as IT power capacity of the Bengaluru data centre |
| Portfolio card | October 2026 | 4.82 | Purpose-built for enterprise workloads, precise to two decimals |
| Annual report chart | Q3 2025 | 4.0 | Bangalore 01, Electronic City, marked operational |
| Factsheet | 2022 | 2.3 | Total power capacity, 600 racks, 150 W per sq ft |
| This registry | — | 4.82 | Current operator card figure |
Read as a sequence rather than a contradiction, the four figures tell a coherent story: 2.3 MW in 2022, 4.0 MW by the 2024 annual report, 4.82 MW on the current card, and a portfolio page that still says 7.6 MW. The 7.6 has been carried forward in Sify’s marketing for years; the 4.82 is what a card-level audit now records.
That matters more than it looks. 7.6 MW is the only figure in the set that cannot be reached from the building’s own rack count without assuming a density the datasheet contradicts — 12.7 kW a cabinet against a stated design of 150 W per sq ft and 600 racks.
Technical datasheets are written for engineers, not for marketing, and they carry the numbers an operator would be embarrassed to contradict: breaker sizes, feeder voltages, fuel storage, rack counts, watts per square foot.
The 2022 Bangalore factsheet gives 2.3 MW, 11 kV feeders, N+N UPS, 48 hours of fuel and 600 racks. Nothing in it is a claim about the future.
Every larger number published since is a claim about capability. A buyer should treat the datasheet as the floor and the portfolio page as the ceiling, and this page prints both.
3The density retrofit, and what it is worth
Bangalore 01 has not been rebuilt. It has been re-powered. Between the 2022 factsheet and the current card the same 600 racks went from carrying 2.3 MW to 4.82 MW — from 3.8 kW a cabinet to 8.0. That is 2.52 MW of new capacity inside an existing shell, with no new land, no new building and no new substation class.
| Route | What it needs | Indicative capital |
|---|---|---|
| Greenfield build | Land, shell, substation, gensets, 24 to 36 months | about ₹139 crore at ₹55.3 cr per MW |
| Density retrofit here | Higher-density racks, in-row or rear-door cooling, busway, PDUs | a fraction of the above |
| Sify’s stated route | Said to be expanding capacity without new buildings | Labelled an estimate in this file |
₹139 crore is what a greenfield 2.52 MW costs at Yotta’s disclosed D4 rate, the closest comparable in this registry for a purpose-built hyperscale build. A retrofit does not cost that, because it buys no land and pours no concrete. Industry ranges put a re-power at a third to a half of greenfield once cooling is upgraded, which would be roughly ₹46 to ₹70 crore for the same 2.52 MW. That is arithmetic on the band, not a disclosure, and it is labelled as such.
The strategic consequence is larger than the building. Every legacy site in this registry is a density retrofit waiting to happen — Vashi at 1.0 kW a rack, Kolkata at about 1.1, Chennai 01 at 4.5 to 7.2. Those four buildings share roughly 9 MW of deliverable power today. Re-powered to 8 kW a cabinet they would carry closer to 18 MW, on land and shells already owned and already connected.
Sify’s portfolio page claims 7.6 MW at this address. The card says 4.82. The 2022 datasheet says 2.3.
All three can be true at once if the building has been progressively re-powered — and if none of them describes the same measurement date. The registry counts the current card figure, because it is the only one tied to a present-tense source.
What a buyer must ask is not how many megawatts the building can eventually carry, but how many it is delivering this quarter. That number is not published for any Sify facility.
4A leased shell running to 2038
The tenure is the least-discussed and most consequential fact about Bangalore 01. A third-party listing records the building as leased, with a lease end date of Q1 2038, about 14,000 sq ft of space and a floor load of 1,000 lb per sq ft. Sify is not the landlord here; it is the tenant of a building it operates as a data centre.
| Party | Effect | Why it matters |
|---|---|---|
| Sify | Fixed occupancy for 12 more years | No redevelopment risk, but no freehold asset to borrow against |
| The landlord | Contracted income from a Rated 3 tenant | A data centre is a very durable tenant once energised |
| A buyer of the business | Operational control, not the asset | Value sits in the customers and the certification, not the deed |
| A competitor | Cannot win this site until 2038 | Site scarcity inside Electronic City Phase 1 is real |
Against a greenfield campus in Aerospace Park, this is the mirror image. Bangalore 02 is freehold-scale ground with 40+ MW of design and a shell being built to suit; Bangalore 01 is a rented floor plate inside a 2006 building in the original IT corridor, held for another twelve years.
That is why the two records belong side by side. Sify runs the connectivity business in Electronic City and the AI-hyperscale business in Aerospace Park, and the two have almost nothing in common except the invoice header.

6Limits and open questions
- Four published capacities — 2.3, 4.0, 4.82 and 7.6 MW. The registry counts 4.82 MW, the current operator card figure.
- The build year is ambiguous — 2006 per the datasheet and a third-party listing, 2011 per the 2025 integrated report.
- The rack count of 600 is from a 2022 document and has not been restated since. Every density figure on this page depends on it.
- Lease details are third-party. The Q1 2038 end date and the 14,000 sq ft area come from a directory listing, not from a filing.
- No PUE is published for this building, so the energy cost of a 2006 shell cannot be quantified.
- Retrofit cost is an estimate built on the replacement band and an industry range, not on a disclosed Sify figure.
- What would close it. One sentence from Sify: current delivered IT load at Electronic City, and the cabinet density sold today.
