Where it sits

Kolkata holds 4 active projects with 150 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 stage was recorded as under construction on 27 March 2026.

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 3 public sources for this project, the latest dated 14 July 2026, and last checked the record on 2 October 2026.
