Your call. Will it be built?

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.

Where it sits

Chennai holds 16 active projects with 819 MW of planned IT load between them, and AirTrunk MAA1 ranks first 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.

AirTrunk has 4 others in India and 7 projects elsewhere in the dataset tracked by ArusGrid, including AirTrunk HYD1, AirTrunk BOM1 (ex-Lumina Airoli) and AirTrunk BOM3 Mumbai. Named funding comes from Blackstone and CPP Investments 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 stage was recorded as at the land and permitting stage on 20 April 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 5 June 2026, and last checked the record on 21 October 2026.

Who uses the compute

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.

Money at this site

ArusGrid estimate, building costabout US$722m to US$1.1bn

No figure has been announced. This range is 128 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.

Benchmark: Turner & Townsend Data Centre Construction Cost Index 2025, as reported by Data Storage Asia. An estimate is never added to any total on the site.

Platform deals that include it
