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.

How well evidenced is it

Construction or financing is evidenced, or several independent signals agree. On record: named funder, three or more sources, dated source in the last 24 months. Criteria.

AI workloads

StatusLikely

Modern greenfield above 100MW by an AI-focused hyperscale developer.

Access to AI chips

GradeNo US licence required

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.

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.
