653 power-bearing data centers mapped worldwide: 5.5 GW operating across 46 countries, 64.9 GW under construction

Asked:

“i want a world map with all datacenters built and under construction. Each datacenter should be a dot or circle with the size proportional with its GW power.”

Asked (follow-up):

“this is us. I asked for world”

This replaces the earlier US-centred report. The power source is now the worldwide Data Centers List directory joined to independent global coordinates (PeeringDB and OpenStreetMap): 552 operational facilities in 46 countries totalling 5.47 GW, plus 101 geocoded under-construction sites with source-stated power totalling 64.9 GW. The map opens on the whole globe — Europe, Asia-Pacific, Africa, the Middle East, Latin America, Canada and the United States are all plotted.

This is not every data center on Earth. Data Centers List tracks 6,120 facilities in 183 countries, but only 914 have capacity populated (71 disclosed, 843 AI-estimated at source), and 552 operational power-bearing records could be name-matched to independent coordinates. It is the best mappable worldwide power-bearing subset assembled here. Capacity figures may be disclosed or AI-estimated at source; Data Center Watch construction MW is source-stated only. Some coordinates are city or campus points rather than building centroids.

Operational Under construction Circle area is proportional to GW; sites under ~0.05 GW are drawn at a 2 px minimum so they stay visible

Announced US construction dwarfs today’s operating base: the 101 under-construction sites total 64.9 GW — nearly 12× the 5.47 GW of the 552 mapped operational facilities — led by the 9.2 GW SoftBank/PORTS campus in Piketon, Ohio. datacentr.net

The largest mapped operational site is not American: Google’s Fredericia campus in Denmark, at 0.386 GW, tops the worldwide operational layer. datacenterslist.com

Outside North America the operational layer is broad: France (57 sites), Australia (56), Germany (48), the UK (40) and the Netherlands (33) each host more mapped facilities than any country except the US (129). datacenterslist.com

The extraction also found under-construction power records in Japan, the UK, Switzerland, Kazakhstan, Poland, Germany, Thailand and Malaysia, but only the US ones had independent geocodes; the rest appear in the coverage table, not on the map. datacenterslist.com

Only the US construction records had independent coordinates and are plotted (via the Data Center Watch layer); the other eight countries’ records show a matching gap, not an absence of construction.

Method: 552 operational facilities from the Data Centers List worldwide directory (6,120 tracked, 914 with capacity: 71 disclosed, 843 AI-estimated at source), name-matched to independent coordinates from PeeringDB and OpenStreetMap; 101 under-construction sites from the Data Center Watch registry (27,897 facilities, 16,287 geocoded; updated 2026-09-27) with source-stated MW only. GW is fully built-out IT power. Circle area scales with GW with a 2 px minimum radius. Rows without positive power or independent coordinates were cut; operational rows from Data Center Watch were excluded in favour of the broader worldwide layer. Some coordinates are city/campus centroids.
