A useful baseline for a fragmented public record.

Current public inventory

Counts update from the same verified records and labeled baseline candidates that power the map and project directory.

Counting rule

One canonical site or campus counts once, even when it contains multiple buildings, phases, or operator listings. “Operating” means current public evidence supports active data-center use. Proposed, construction, contested, and dormant records remain visible but are not included in the operating count.

How visibility works

• Baseline candidates are not formal verification. A credible non-directory source can make a project useful enough to map when its candidate status and confidence remain visible.
• Directory records are leads, not a backlog. Directory-only observations remain private unless stronger evidence makes them useful.
• Facts are evaluated separately. Status, capacity, place, ownership, utility context, and chronology can carry different evidence strength.
• Confidence describes evidence quality. It is not advocacy and does not imply that every project detail is known.
• Hotlist signals remain reviewed records. A published issue preserves what changed, why it mattered, and the sources available at that time.

Location and scale

Map records distinguish verified addresses, parcel or site centroids, approximate jurisdiction-level points, and withheld precise locations. A confirmed major-project marker requires reported capacity of at least 100 MW. A major-scale candidate has credible campus-scale evidence but lacks comparable public MW capacity.

Independent counting context

These sources do not define the Atlas inventory; they provide useful context for differing definitions and counts.
