Polarnode data centre projects in Europe
Our European pipeline tracker follows 3 data-centre projects of 5 MW or more that Polarnode develops or co-develops, in 1 country; 1 is permitted or already being built. All of them are in Finland.
33% are permitted or being built, against 43% across the whole tracker, so the pipeline is earlier-stage than the European average. The milestones we hold run from Dec 2025 to Aug 2026.
Projects by stage
- In planning2
- Under construction1
What the capacity figures measure
- Facility, campus or unstated basis1
- Grid connection1
- First phase only1
Stated size, where a figure is published
- 50 to 99 MW1
- 250 MW and above2
Bands mix the bases above (a grid connection is larger than the IT load it serves), so read them as orders of size. Capacities are counted, never added together.
Where Polarnode is building
Projects by country, with the metro markets inside each country. Each name opens the market page.

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, and it holds the projects we have found and checked, not every project a company has.
- We count the projects Polarnode develops or co-develops; a joint venture counts once for each partner. Tenancies, land ownership, construction contracts and financing are not counted.
- Markets follow the tracker: a metro market includes the region around the city, and a national market covers the rest of the country.
- Stated capacities use different bases, so projects are counted by basis and in size bands and the figures are never added together.
- ScienceShot is independent of Polarnode. The figures come from public filings and announcements, not from the company.
- This page shows aggregates. The pipeline tracker and the market pages hold the wider picture.
