Data centre projects in Hungary
These are the data-centre projects of 5 MW or more in Hungary that our pipeline tracker follows: 1 project, none of them permitted yet.
Projects by stage
- Announced1
What the capacity figures measure
- 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.
- Jun 2026AI data centre near Paks nuclear plant project company 3D Zrt. reports land acquired, grid planning advanced and government consultations done; platform to scale up to 300 MW of AI and HPC capacity with operations targeted for Q4 2028 Announced

Formal refusals and bans since 2025
Verified decisions only. Absence is not evidence of low planning risk.
No formal refusal or ban recorded for Hungary in this register. The register covers decisions we have verified, not every decision taken.

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.
