How To Read This Taxonomy

This taxonomy is one lens on a live dataset covering 346 AI data centers across 64 countries and 225 tracked operators.

Why organize facilities by capacity tier?

Capacity bands turn a long directory into a strategic map, separating routine deployments from the 500 MW to 1 GW campuses that reshape utility planning and regional competition.

How should readers interpret the largest tiers?

The biggest tiers surface projects most likely to drive chip-cluster concentration, transmission upgrades, power procurement innovation, and investor attention.
