The Pipeline
Tracked AI data-center capacity by stage, in gigawatts. Colored by stage: only energized watts are real today.
Only energized watts move the Clock. Everything else is a claim about the future.

Cells are exclusive tranches: a site's GW is counted once, at its furthest-attested stage.
† includes rows whose GW is undisclosed — the true total is higher than the sum shown.
