Next gate to watch: Tenant or own use.
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 Nxtra Kolkata (Bengal Silicon Valley) ranks third 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.
Nxtra has 1 other in India tracked by ArusGrid, including Nxtra Siruseri campus (CHE 2, CHE 3, DC3). Named funding comes from Bharti Airtel on the equity side. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The dated record runs from under construction in November 2022 to under construction on 27 March 2026. Power comes from Eight renewable energy partners (unnamed) through a renewable power purchase agreement (reported, unconfirmed).
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 5 public sources for this project, the latest dated 14 July 2026, and last checked the record on 20 October 2026.
Construction or financing is evidenced, or several independent signals agree. The rules are fixed and published on the Methodology page.
Reaching this stage requires a dated construction source, which corroborates the project on its own.
Airtel FY26 annual report lists Kolkata among AI-ready campuses designed for 60 to 140 kW racks and liquid cooling.
This country carries no US destination-based licence requirement for advanced AI chips as the rules are enforced today. Access is a commercial matter between the project and its vendors. Criteria are published on the Methodology page.

No tenant disclosed. Most colocation leases are confidential, so this says nothing about occupancy. Not yet checked against second-order sources.
No figure has been announced. This range is 25 MW of planned IT load times a published benchmark of US$6.64 per watt for Mumbai, plus or minus 15 percent, with 10 percent more at the top for liquid cooling because the project is AI-positioned. It covers the building and its mechanical and electrical plant. It excludes land, grid works, servers and fees.
