On 13 October 2026, at the inauguration of its Patna data centre, CtrlS signed a letter of intent with the Government of Bihar to invest ₹10,000 crore in a 150 MW hyperscale AI factory at Bodh Gaya. That is ₹66.7 crore a megawatt — and the building the same company had just opened, 100 kilometres away on the same day, cost about ₹34.5 crore a megawatt. No land, power connection, construction schedule or precise site has been published. This record adds zero megawatts to the registry, and it is a record anyway, because the price of a promise is the most useful number in the file.
1At a glance
2₹66.7 crore a megawatt
Divide the promise by the promise and you get a price. Put it beside the price of the building the same company opened the same day and the gap is the story.
| Item | Basis | ₹ crore per MW |
|---|---|---|
| Bodh Gaya, as announced | ₹10,000 crore ÷ 150 MW | 66.7 |
| Kolkata phase one, as announced | ₹370 crore ÷ 16 MW | 23.1 |
| Patna Edge DC 2, as announced | ₹400 crore ÷ 11.6 MW | 34.5 |
| CtrlS Kolkata, the operator’s own quote | stated directly | 35.0 |
| Kolkata campus, as announced | ₹2,200 crore ÷ 60 MW | 36.7 |
| This registry’s new-build band | other operators’ disclosures | 52 to 70 |
Four of the five CtrlS figures sit between ₹23 and ₹37 crore a megawatt — a company that builds cheaply, consistently, in tier-2 cities, on land it gets from state governments. The fifth is the letter of intent, at nearly double.
Two explanations fit and Gridvik does not choose between them. An AI factory is a different building: denser power, liquid cooling, more expensive electrical topology, possibly its own generation and a green-energy package. Or the ₹10,000 crore includes things a colocation shell does not: land at commercial rates, a solar plant, and fit-out that a colocation operator normally leaves to its tenants. Both are ordinary. Neither is published.
If Bodh Gaya is really an AI-grade build, ₹66.7 crore a megawatt tells you what AI capacity costs in India in 2026, and it is 1.9× what colocation costs the same firm.
If it is a colocation shell with a bigger number attached, then ₹66.7 crore is a marketing figure and the real build will come in near ₹35. Anyone pricing a competing AI campus needs to know which.
3Why the price is double
| Reason | What it would do to the number |
|---|---|
| Density | An AI hall at 100 to 170 kW a rack needs liquid cooling, much heavier electrical distribution and a different building. Cost per megawatt rises before cost per rack does |
| Scope | A colocation shell leaves white space for the tenant. An AI factory may include the IT it serves, which moves the number by a factor of two or more |
| Energy | If a captive solar plant is inside the ₹10,000 crore, several hundred megawatts of generation are being bought with it |
| Land | State allotment versus open-market purchase, which in Bihar is cheap and in Maharashtra is not |
There is a fifth explanation that costs nothing to state: a letter of intent is written before anything is designed, and the number in it is a headline that both parties want to be large. ₹10,000 crore is a round figure with a lot of zeroes and it converts neatly into a billion dollars, which is the currency a government press release prefers.
What is not in doubt is the operating company’s direction. CtrlS says it will build over 4.4 GW by 2030. A rating agency projects its operational capacity at 950 to 1,000 MW by 2029. This letter of intent is 3.4% of the company target and 15% of the analyst projection, and it is the largest single announcement the company has made in Bihar.
4Bodh Gaya
Bodh Gaya is a pilgrimage town of about forty thousand people in Gaya district, and a UNESCO World Heritage site. It is not an obvious place to put 150 MW of accelerated computing, and that is worth saying plainly rather than treating as a puzzle.
| Requirement | Status |
|---|---|
| Land | not allotted in any public document |
| Power connection | not stated. 150 MW of IT load is roughly 230 MW of facility load at a PUE of 1.55 |
| Water | not stated. At a published benchmark of 20 MLD per gigawatt, 150 MW implies about 3 MLD, or three million litres a day |
| Fibre route | not stated. The nearest large cable landing is hundreds of kilometres east |
| Construction schedule | not stated |
| Anchor customer | not stated |
None of those is disqualifying. Bihar has land, it has a government that wants data centres, and Gaya has an international airport used by pilgrims. A site 100 kilometres from Patna can be served from the state capital’s utilities and workforce.
But three million litres of water a day in a district that is not documented as water-surplus is the question a serious buyer asks first. The state has not published an allocation, and neither has the company.
5A letter of intent is not a project
In this registry, an announcement gets a record and no megawatts. That is the whole discipline, and this record is the clearest example of why.
| Stage | Evidenced today |
|---|---|
| Letter of intent | yes, reported 13 to 15 October 2026 |
| Definitive agreement | no |
| Land allotment or purchase | no |
| Power sanction or connection agreement | no |
| Environmental or building permit | no |
| Construction start | no |
| First phase energised | no |
Every step above has failed to happen for large Indian data centre announcements within the last two years, several of them in this registry. Some have failed at step two. A registry that counted letters of intent would be a press-release index, and its total would be meaningless — the counted total here is 2,420.4 MW across 241 additive records precisely because the announcements are held outside it.
Either a land allotment, a power sanction and a foundation stone appear, and the record is upgraded with a phase-one capacity.
Or nothing appears, and the record stays exactly this size — a ₹10,000 crore sentence with a date on it. Both outcomes are useful, because the reader can see which one happened.
