On 1 October 2026, at the launch of Maharashtra’s Invest Maharashtra authority, Cortex Data Centres — a subsidiary of New York–headquartered The Chatterjee Group — was listed against a ₹60,990 crore proposal for computing infrastructure in Navi Mumbai and 10,000 jobs. It was the largest data-centre line in a single-day MoU event worth ₹8.57 lakh crore. No capacity was published. Three weeks later the company formally announced its entry into the sector with a 2 GW national ambition and stated that no location had been finalised. This record holds those two statements at the same time, because they are both on the public record and they do not agree.
1At a glance
2₹60,990 crore and no megawatt
This is the largest single data-centre number to come out of the 1 October event and it carries less engineering detail than a ₹1,500 crore approval. There is a rupee figure, a district, a job count, and nothing else.
The spread — 871 to 1,173 MW — is the honest range for what this money could build at rates that have actually been paid in India. It is not a forecast and it is not carried into the registry. What it does is price the announcement: a ₹60,990 crore commitment with no megawatt attached is roughly a 900 MW to 1.2 GW programme, or it is something else entirely.
State MoU lists carry rupees and jobs because those are what a state can count. They do not carry megawatts because a state does not design the building.
In this registry, a record with rupees but no megawatts is not a smaller version of a data centre. It is a financing intention. Until a plot and a design exist, the capacity is a number waiting to be chosen.
3The 2 GW that this money cannot buy
Three weeks after the MoU was reported, Cortex announced its entry into the data-centre business: 2 GW of AI-ready capacity across India’s Golden Quadrilateral, developed on land parcels the group already holds, with the first facility ready 18 months after construction starts and 51% green power. The CEO is Rahul Sharma. The company explicitly said there is no fixed number of facilities yet.
The important point is arithmetic, and it is not in any of the coverage.
| Measure | Value | n |
|---|---|---|
| Capital needed for 2 GW at ₹52 crore/MW | ₹1,04,000 crore | the cheapest rate paid in this registry |
| Capital needed for 2 GW at ₹70 crore/MW | ₹1,40,000 crore | the upper end of observed build cost |
| Announced MoU value | ₹60,990 crore | 43.6% to 58.6% of the above |
| ₹60,990 crore expressed per megawatt, if it were the whole 2 GW | ₹30.5 crore per MW | below the cost of building a shell, let alone fitting one out |
So the MoU cannot be financing the 2 GW. Either the ₹60,990 crore is a first tranche against a much larger eventual programme, or the 2 GW is a decade-long aspiration that will be funded from somewhere else. Both are legitimate. What is not legitimate is quoting the ₹60,990 crore and the 2 GW in the same sentence, which is how the two items now circulate.
Treating ₹60,990 crore and 2 GW as one project produces ₹30.5 crore a megawatt — a figure that would imply Indian data centres cost less than half what they actually cost.
Gridvik records zero megawatts for this record. If the 2 GW ever acquires a site list, it becomes a programme of separate records, not one number.
4Who TCG and Cortex are
The counterparty matters more than usual here, because a ₹60,990 crore proposal from a first-time operator has to be read against what the parent can actually do.
| Entity | Position |
|---|---|
| The Chatterjee Group | New York–headquartered private equity and industrial holding group. More than $4 billion deployed. Portfolio in petrochemicals, life sciences, technology, financial services and real estate. This is a capital allocator, not a data-centre operator |
| Cortex Data Centres | The group’s data-centre subsidiary, described on its own site as a TCG venture. No operating campus, no published customer, no disclosed rack count |
| Land position | The company says it will use existing land parcels held by the group. No parcel has been identified, sized or valued |
| Operating experience | Not stated in any public material. This is a first campus for the entity |
Existing land is a real advantage and should not be dismissed — site acquisition and permitting are where Indian data-centre schedules usually die. But land is not power, and power is what a 900 MW to 1.2 GW programme needs. Maharashtra has been generous with MoUs and slower with energisation.
5Navi Mumbai: two accounts
Two official-sounding statements, twenty-one days apart.
| Date | Source | Statement |
|---|---|---|
| 1 October 2026 | Maharashtra government MoU listing | Cortex Data Centres, ₹60,990 crore, Navi Mumbai, 10,000 jobs |
| 3–5 October 2026 | Financial Express, ETDatacenters, DQ India | Repeats Navi Mumbai and the value, citing the state list. No capacity, no plot, no counterparty detail |
| 22 October 2026 | Cortex launch coverage, BusinessLine and BW Businessworld | Company announces its sector entry. No locations finalised. First facility ready 18 months after construction begins |
This is not a contradiction that implies anyone lied. A state publishes where it wants an investment to land; a company announces when it is ready. But a supplier reading "Navi Mumbai" as a confirmed micro-market would be planning against a decision that has not been made. Navi Mumbai is plausible — the group’s land, the state’s incentives and the customer base all point there — and it is not confirmed.
For anyone selling into this programme, the practical consequence is simple: there is no parcel to visit and no substation to survey. Everything below the state level is still open.
6The 18-month claim
Eighteen months from first shovel to operational readiness is fast for India and not impossible. Yotta, CtrlS and AdaniConneX have all delivered phases inside comparable windows. What makes the claim hard to assess here is that no shovel date exists, so the promise cannot be tested — 18 months from an unnamed start date is not a schedule.
Two of six stages are evidenced. The four that decide whether a data centre exists are not. That is the whole status of this record, and it is why it carries zero megawatts and zero capital deployed.
The 51% green-power target deserves the same treatment. In this market it has become a standard clause — Trentar, ReNew and Cortex all announced the same figure within eight days of each other. None of the three has published a power purchase agreement, a generation source, an open-access approval or a storage duration. The number is a design intent, and it will be the hardest part of the programme to deliver.

| ₹30.5 crore per MW | ₹60,990 crore ÷ 2,000 MW. Shown to reject the pairing, not to value the project | Arithmetic |
| $6.90 billion | ₹60,990 crore ÷ 88.40. Fixed quarterly rate, no live FX | Arithmetic |
| 10,000 jobs | State MoU listing | Unverified |
