Fourteen-building Amazon campus; the tracker lists Anthropic and Project Rainier as speculative links. The planned figure assumes Buildings 6–14 start by Jul 2026 and finish by Sep 2028 (tracker estimate); Amazon has published no MW for this site.
Current and planned figures may use different power bases. Planned power is the end state, not additional capacity to add to the current figure. An unspecified basis remains unknown. A figure marked est rests on at least one source other than the operator’s own announcement.
