Marktüberblick
Data center tracker: key facts
Capacity under construction or planned (25,298 MW) is 2.9 times the operational base of 8,624 MW.
The three largest operators by operational capacity, Centersquare, CyrusOne and Vantage Data Centers, hold 30% of tracked operational MW.
PowerHouse Data Centers has the largest development pipeline in the tracker: 2,635 MW under construction or planned.
The largest operational facility we track is JHB1 (Vantage Data Centers, Kulai, Malaysia) at 300 MW.
The largest project in the pipeline is PowerHouse PAX-1 (1,350 MW, planned).
United States accounts for 29% of tracked capacity (875 facilities).
By type, the tracker lists 1,253 colocation, 538 hyperscale and 69 edge facilities.
52 facilities publish a PUE figure; the lowest is 1.05 at Leibniz Supercomputing Centre (LRZ) (Leibniz Supercomputing Centre (LRZ)) and the median is 1.30.
691 of 1,938 facilities have a capacity stated by their source; the totals above count only those.

Every facility in the tracker worldwide, in Excel, with sources and status history. A fresh file every month for a year.
Sources: operator websites and announcements, stock-exchange filings, planning and government records, and named trade publications. Never another directory.
A second analyst re-opens each source before a facility is published.
Capacity, size, year, tier and PUE appear only when the source states them. Nothing is estimated.
Status: operational, under construction (building work started) or planned (announced or permitted, not yet under construction).

Questions
How many data centers does the tracker cover?
As of October 2026 the tracker lists 1,938 data centers in 28 countries from 361 operators, with 8,624 MW of stated operational capacity. New countries are added every week.
Where does this data come from?
Every facility comes from a page we opened: the operator’s own website or announcement, a stock-exchange filing, a planning or government record, or a named trade publication. A second analyst re-opens the source and checks the name, location, status and capacity before the row is published. We do not copy other data center directories.
What does the MW figure mean?
We show IT (critical) capacity when the source states it, otherwise the total or utility capacity the source gives, and say which in the facility’s note. When a source gives no capacity, the field stays empty. We never estimate it.
How exact are the map locations?
When the source gives an address or coordinates we use them. Otherwise the dot sits at the centre of the facility’s city (marked as approximate), using the GeoNames gazetteer.
How often is it updated?
The tracker is updated every week as new facilities are announced and existing ones change status. Each row shows the date it was last checked.
Can I get the data in Excel?
Yes. Each country with 50 or more facilities has a Capacity Sheet in Excel with every facility, its source link, the status history and summaries. Our analysts can also prepare an operator extract or a custom cut.

Our analysts prepare country and operator extracts in Excel, capacity pipelines and site-selection briefings.
