The quiet buildout: inside India's data centre expansion

India's data centre pipeline has roughly tripled in announced capacity over the past three years, driven by cloud providers racing to onshore storage and by the sudden appetite for compute to train and serve AI models. But the geography of that buildout is far from even.

Compute capacity follows electricity, and increasingly follows firm, round-the-clock power contracts rather than merely cheap ones. States that can guarantee uninterrupted supply and predictable land approvals — chiefly Maharashtra, Tamil Nadu and Uttar Pradesh among the leaders — are attracting the largest hyperscale facilities, while other states are left competing on tax incentives and duty exemptions alone.

Water use for cooling has emerged as the second major constraint, and it is increasingly a local political question rather than a purely engineering one. Large facilities can consume as much water in a day as a small town, and several proposed sites have run into objections from local farming communities worried about groundwater depletion during dry months.

"Everyone talks about chips, but the real bottleneck in this country right now is substations and transmission corridors," said an energy sector analyst at an infrastructure advisory firm. "A facility can have all the capital it needs and still wait eighteen months for a grid connection."

Renewable procurement has become a competitive differentiator for operators seeking corporate sustainability commitments, with several announced projects tying a third or more of their power sourcing to dedicated solar and wind capacity built alongside the facility rather than drawn from the general grid.

Whether the full pipeline of announced capacity actually gets built remains an open question. Industry executives privately concede that a meaningful share of announced projects will be delayed or scaled down as land, water and grid approvals move slower than initial press releases suggested.
