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.
Chennai holds 16 active projects with 819 MW of planned IT load between them, and Iron Mountain Chennai (CHN-1 and CHN-2) ranks 10th by planned capacity. Of those, 10 are operational, 1 is operational and expanding, 2 are under construction, 2 are at the land and permitting stage and 1 is announced only. Published colocation vacancy in Chennai was 24.2% as of June 2025. Vacancy excludes hyperscaler self-build.
Iron Mountain has 1 other in India tracked by ArusGrid, including Iron Mountain MUM-3. No tenant has been disclosed, which is normal for colocation and says nothing about occupancy.
The build is phased. CHN-1 at 23 MW is under construction with a 2026 target; CHN-2 at 19 MW is announced. The stage was recorded as under construction on 13 April 2026. Power comes from Not named through a dedicated substation (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 4 public sources for this project, the latest dated 13 April 2026, and last checked the record on 22 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.
Marketed as AI ready with liquid cooling readiness, no tenant named.
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.
