Norway · Operational + expanding
| Status | Operational + expanding |
|---|---|
| Capacity (MW) | 37 operational + 43 contracted under construction; ~200 potential Sources: www.globenewswire.com |
| Power source claim | Hydropower + fjord seawater cooling (operator claim). WUE: confirmed directly on Lefdal's own site as effectively zero — no evaporative cooling, flow-through fjord water cooling (structural, not behavioral). Sources: www.lefdalmine.com · lefdalmine.com |
| Published PUE | ~1.08–1.1 (cited by Rittal, minority owner — semi-primary source) Sources: www.rittal.com |
| Ownership / jurisdiction | SIGNED, NOT CLOSED — do not report as completed. 3i Infrastructure plc (UK-listed) agreed to acquire a majority stake (~€300M, announced Mar 2026) from Columbia Threadneedle's ESIF fund (chain to Ameriprise, US); reported 'expected to complete summer 2026.' As of 23 Jul 2026, Lefdal's own ownership page still lists Columbia Threadneedle (66.67%) and Rittal/Friedhelm Loh (Germany) as 'the main shareholders' — no mention of 3i. Treat current disclosed ownership as Threadneedle/Rittal until Lefdal's own site updates or right-of-reply confirms closing. Sources: www.3i.com · lefdalmine.com |
| AI / GPU relevance | Hosts containerized HPC/AI deployments (tenant mix UNVERIFIED) |
| Verification notes | Heat reuse: no named offtaker found — absent/N/A pending right-of-reply. Right-of-reply Q1: has the 3i transaction closed, and if so when? Right of reply sent 21 Aug 2026; response window open until 4 Sep 2026. |
