Where to Build: Data-Center Siting Index

The other side of water risk. We rank the major U.S. data-center markets on the three factors that actually decide a build — power (interconnection queue & time-to-energize), water (cooling headroom), and hazard (natural-hazard safety) — from public ISO, USGS, and FEMA data. Higher score = better site.
