Facilities

Coverage varies by source: 89.9% of the Epoch AI GPU Clusters rows have a power, GPU or compute figure or a description, compared with 0.0% of the OpenStreetMap (tagged data centers) rows.

Counts cover 4,308 public facility records, read 13 Nov 2026. The smaller catalogues are summed in one row, so its share mixes both kinds of source.

The full dataset has 4,402 facility records across 110 countries; 94 are licensed and counted only in totals, and the other 4,308 are open to browse in this register.

Power figures include both reported values and estimates; each facility names its source and links to it where its record has a link.

Facilities with a power figure: Facilities open to browse of which some record states a power figure, operating, under construction, planned or for a whole campus, after corrections. A campus entered by two catalogues is one facility. Licensed records are left out.

Total, MW gives each facility’s power figure. With a figure left out of operating totals, whole campus marks a campus build-out or envelope, and planned a site announced, permitted or under construction. A decommissioned, cancelled or earlier-phase figure, an expanding site whose operating share is not recorded, or a figure whose stage or campus scope is not recorded has no word, and its Stage names it. Operating, MW gives the figure counted as operating capacity; beside a whole-campus total it gives the operating part where a facility’s record supports one, counted in operating totals through another record of the same site.

83 power figures are withheld from the register: 36 under an editorial correction, 33 so that a campus counts once in recorded-power totals and 14 counted in operating totals through another record. Select Withheld in a row for that record’s own reason.

Each circle on the chart is a facility with a power figure, and a circle’s area is in proportion to its megawatts; the circle marked 100 MW by the chart gives the scale, which is the same for every stage at any window width. Each stage’s circles are packed largest first, each at the free place nearest the centre, once for the whole list, so a filter fades a circle where it is. A figure that is not counted as operating capacity is drawn pale. 3 pale circles each contain a dark circle for the operating plant inside a build-out or later-phase figure, counted in operating totals through another record of the same site, as on the map.

A search matches a facility’s name, with corrections applied, and the name of its country. The count beside each filter choice is the number of facilities it would list with the other filters as they are.
