This project is built or running, so every gate counts as passed.
Build odds is ArusGrid's reading of the public record, not a forecast, a rating or advice. It counts the gates this project has passed in public sources. Private progress does not show, a passed gate can be undone, and projects that pass every gate still stop. The method has not yet been tested against outcomes. How it works.
How India approves, powers and taxes data centers is on Data center rules in India.
Kolkata holds 4 active projects with 135 MW of planned IT load between them, and CtrlS Kolkata ranks first by planned capacity. Of those, 3 are operational and 1 is under construction. Published colocation vacancy in Kolkata was 17% as of June 2025. Vacancy excludes hyperscaler self-build.
CtrlS has 4 others in India tracked by ArusGrid, including CtrlS Chandanvelly datacenter park, CtrlS Mumbai datacenter campus (DC1 to DC7) and CtrlS Bodh Gaya AI Factory. It sits on the CtrlS Kolkata (Bengal Silicon Valley) campus. Named funding comes from CtrlS Datacenters on the equity side. No user of the capacity is on the public record as of 2026-10-02, after a check of operator, landlord, contractor, regulator and lender documents. Most colocation leases are confidential, so this says nothing about occupancy.
The build is phased. Phase 1 at 16 MW is operational with a 2025 target; Phases 2 to 4 at 44 MW is announced. The dated record runs from under construction in November 2023 to operational on 12 August 2025. The money on record is INR 22bn (about US$255m) as of August 2025, the announced investment.
The US export control position for advanced AI chips in India, as of 27 September 2026, is recorded as “No US destination-based licence requirement as enforced”. ArusGrid holds 7 public sources for this project, the latest dated 14 August 2025, and last checked the record on 21 October 2026.

Checked on 2026-10-02. No user of this capacity is on the public record. ArusGrid read the operator's releases, the landlord's and contractors' exchange filings, regulator and lender documents and interconnection records. Most colocation leases are confidential, so this says nothing about occupancy.
The figure covers the whole campus.
ArusGrid estimate, grade C. Published band for this country. Priced on the hyperscale band, which already reflects anchor deals. No usable capex for this site. Electricity unstated in the band. An estimate, never a quote, computed by fixed rules published on the Colo prices page and never counted in any total.
