Practitioner-written assessments of facilities and providers. Skeptical of greenwashing; specific about power, PUE, grid, and jurisdiction.
On Norwegian ownership in this batch: Norwegian ownership of Norwegian AI infrastructure is thin and getting thinner among the commercial operators — Green Mountain (Israeli), Vaultica (US), STACK (US), Lefdal (US, transitioning to UK), Bulk (a Norwegian-registered plurality holder that is itself majority foreign-owned).
The clearest exceptions are Norwegian, but they are not a competitive private market. Skygard is backed by Telenor and Hafslund — the state and the City of Oslo. Nscale's Narvik joint venture runs through Aker, private capital, but a single large industrial group rather than a field of contenders.
So the picture is not "Norway lost control." It is narrower and more interesting: among the MW-scale operators assessed in batch one, what Norwegian ownership remains sits with the state, a municipality, or one industrial group — not with a private market.
That boundary matters. Further down the size range the picture differs: Blix Solutions, added in batch two, is Norwegian-owned by one named private individual with no fund or holding layer at all. The claim above is about the largest facilities, not about Norwegian datacenter operators as a whole — see What we include for how the batches are bounded.
-
Pre-review assessment of Blix Solutions' two Oslo sites — an ownership chain that ends at one named Norwegian individual, paired with a self-published PUE well behind the MW-scale operators.
-
Pre-review assessment of Bulk Infrastructure's ownership look-through — a plurality, not a majority, and an unconfirmed calculation that could put foreign capital in effective control.
-
Assessment of Green Mountain's four Norwegian sites — the strongest per-site PUE evidence in the dataset and one active heat-reuse project, paired with 100% foreign ownership and a China-linked anchor tenant.
-
Pre-review assessment of Nscale's Glomfjord site and the much larger Aker Nscale Narvik joint venture — testing the 'sovereign AI' pitch against the cap table.
-
Pre-review assessment of Lefdal — a signed-not-closed foreign ownership transition, weighed against hosting Sigma2's national HPC infrastructure.
-
Pre-review assessment of Skygard's three Oslo-area sites — Norwegian state and municipal ownership, the largest heat-reuse claim in the dataset, and capacity figures that simply aren't public yet.
-
Pre-review assessment of STACK's remaining Nordic footprint — the OSL03 Fetsund campus and OSL04, plus registry evidence hinting at sites not yet in this dataset.
-
Pre-review assessment of Vaultica's Oslo, Copenhagen and Stockholm sites — a confirmed ownership chain to Apollo Global Management, alongside open questions about corporate identity and a capacity figure that won't settle.
-
A first-pass assessment of Verne's 140+ MW Icelandic HPC/AI campus: real geothermal advantage, French ownership, and the claims still to verify.
Corrections to the note above
25 August 2026 — scope qualifier added. The note concluded, without qualification, that "what Norwegian ownership remains in this sector sits with the state, a municipality, or one industrial group — not with a private market." That holds for the MW-scale operators in batch one, but not for Norwegian datacenter operators generally: Blix Solutions is Norwegian-owned by one named private individual. The sentence is now bounded to batch one, and a paragraph on Blix has been added. This correction happened because an operator raised the omission publicly — we think showing where corrections come from is more trustworthy than appearing to catch everything ourselves. The threshold for who gets assessed is now published under What we include.
24 August 2026 — Aker misclassified. An earlier version grouped Aker — private Norwegian industrial capital controlled by Kjell Inge Røkke — with Telenor and Hafslund as public-sector capital, concluding that "Norwegian control in this sector increasingly means public-sector capital, not private." That conclusion doesn't hold once Aker is correctly classified as private capital. The original wording it replaced read: "The clearest exceptions are where the Norwegian state and municipalities are directly involved: Skygard (Telenor, Hafslund) and, partially, Nscale's Narvik JV via Aker. Norwegian control in this sector increasingly means public-sector capital, not private."
