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, committed or approved capital, three or more sources, dated source in the last 24 months. Criteria.

AI workloads

StatusLikely

Hyperscaler self-build land held since 2022; an environmental clearance application reportedly states 272MW IT load but was not verified.

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.

Water0.01 MLD Reported source ↗
Residents say AWS told the state in August 2025 it needed about 125 KLD and that TMC agreed to supply 12 MLD of recycled sewage water. Unverified. about 0.01 MLD (10,000 litres a day) for drinking and domestic use, per AWS
Cooling Reported source ↗
AWS says it will not use drinking water to cool servers.
WaterRecycled wastewater · Thane Municipal Corporation (treated sewage water) · 115 m³ a day Confirmed source ↗
Amazon's own page gives total site water use of 125 KLD: 10 KLD for basic human needs and 115 KLD of treated sewage water from TMC for landscaping and irrigation. Amazon calls these projected figures from early designs. This is the operator's own figure for the 125 KLD that the notes attribute only to activists, and it is consistent with Amazon's 0.01 MLD for human use. It does not support the 12 MLD or 100 MLD figures cited by opponents. Page last modified 2 Sep 2026.
CoolingClosed-loop cooling Confirmed source ↗
Amazon says the site uses closed-loop cooling that does not use any water for cooling, with no evaporation, no potable water draw and no wastewater discharge.
