These are estimates from Epoch AI’s Frontier Data Centers tracker (CC BY) — a curated set of the largest disclosed AI campuses, not a census, and currently US-heavy. This campus is located to locality-level precision (29.42, -98.50). Power, compute and cost figures are Epoch estimates that change as sites are built and disclosed. Snapshot taken 2026-06-24.
