Reliance Jio — Jamnagar AI Mega Campus

Reliance has publicly positioned Jamnagar as the anchor site for its national AI infrastructure buildout, with official 2024 and 2025 statements describing gigawatt-scale, AI-ready data centers powered by the group's green-energy assets. More recent 2026 reporting attributes an additional detail to Mukesh Ambani: more than 120 MW is expected to come online in the second half of 2026 as an initial phase within that broader Jamnagar program. For now, the safest reading is that Jamnagar is an announced multi-phase AI campus rather than a fully specified, independently documented single building.

That distinction matters because the public record is still stronger on strategic intent than on campus-level engineering detail. Reliance has clearly tied the project to sovereign data residency, national-scale training and inference, and integration with its wider energy and telecom footprint. The exact site layout, final equipment mix, cooling design, and delivery sequence, however, remain only partially disclosed in public sources.

The 120 MW figure used in this record should therefore be read as the reported first online tranche, not the total ambition for Jamnagar. The larger program is described in company-linked and market reporting as gigawatt-scale and phased over time, with Google also naming a Jamnagar cloud region built for Reliance. As firmer documentation appears, this page should be updated with clearer phase boundaries, named counterparties, and any verified commissioning milestones.

For adjacent context, compare this record with other India entries on AI Data Center Index and use sibling property [Silicon Bench](https://siliconbench.radicchio.page) to assess how announced national AI infrastructure programs map to actual accelerator deployment trajectories.

**Note:** Source quality is materially better than before, but this remains an announced/planned project with incomplete public technical disclosure.
