Borealis Data Center — Blönduós Campus

Borealis Data Center runs an independent campus in Blönduós, in the north of Iceland, sited beside the Blanda hydropower station for direct access to renewable generation. The campus connects to the high-voltage transmission grid with a 63 MW+ feed to the adjacent substation, which the operator describes as designed to a Tier 3-equivalent standard, and Borealis has signed a 12 MW power-purchase agreement with national utility Landsvirkjun to support further expansion — against a stated long-term expansion capacity above 100 MW. The site runs on 100% renewable energy and the operator cites a PUE as low as 1.03, reflecting Iceland's cold climate and extensive free-cooling potential. Borealis positions the campus for high-performance computing and AI workloads specifically, connected via four subsea fiber cables, rather than marketing an independent Uptime Institute Tier certification (none appears on record for the site). The operator does not publish a specific building-level breakdown, year-opened date, or floor area for the campus, describing it instead as a single expandable site.
