  • Facility, campus or unstated basis1

Each project’s capacity is quoted on its own stated basis, so the figures are never added together.

What changed

No milestone in the last 90 days. The newest check was on 11 Oct 2026; each row below shows its own.

Method

The pipeline covers data-centre projects of 5 MW or more, or with no capacity published, that are announced, in planning, permitted or under construction and not yet fully operating. It is not a list of operating facilities. A metro market follows the tracker’s own market field, so it includes the region around the city; a country page covers every tracked project in the country.

  • Projects: each row is the latest public milestone we found for the project, with the date it was last checked; the pipeline tracker holds every project.
  • Over a year: national averages for the latest full year, the same figures the siting cost ranking uses.
