Lefdal Mine Datacenter

What Lefdal Mine Datacenter does

Lefdal Mine Datacenter (LMD) operates an underground data center campus built inside a former olivine mine on Norway's west coast near Nordfjord, with headquarters in Måløy. The facility spans up to 75 chambers across six mine levels with potential white space of 120,000 m² and a roadmap to 200 MW of IT capacity; as of early 2026, 37 MW is operational and 43 MW under construction. The site's core technology is a fjord-water cooling system that draws year-round 8°C seawater from 100 m depth via siphon-driven circulation through redundant PE piping into 12 heat exchangers delivering 90 MW of cooling (expandable to 200 MW), combined with 132 kV dual power feeds, modular 30 MW transformer increments, and Uptime Tier III design with ISO 9001/14001/27001/45001 certifications. PUE ranges from 1.08 to 1.15 depending on cooling mode, with immersion cooling achieving sub-1.10 and direct liquid cooling supporting GPUs above 1,000 W TDP; IT spaces sit 600-700 m inside the mountain for natural EMP protection and a single controlled entry point.

Core offering

Lefdal Mine Datacenter operates an underground data center campus built inside a former olivine mine on Norway's west coast, providing colocation, wholesale built-to-suit, and IT container hosting services. The facility leverages cold fjord water (8°C) for cooling and Norway's surplus renewable hydroelectric power, delivering high-density HPC infrastructure with industry-leading energy efficiency. Customizable capacity ranges from individual racks to private suites and dedicated data halls, with pay-as-you-grow scaling up to 200 MW.

Product overview

Lefdal Mine Datacenter operates an underground data center campus in a former olivine mine on Norway's west coast, offering a modular and scalable colocation platform. The core offering is Colocation Services (racks, cages, private suites, data halls) paired with Built-to-Suit wholesale options and IT Container solutions. Advanced cooling is delivered through three specialized HPC sub-products: Direct Liquid Cooling (DLC), Immersion Cooling, and Air Cooling—each supporting different density requirements. Connectivity Services provides carrier-neutral network access through multiple providers. Operational Services include Design and Build, Smart Hands technicians, and 24/7 NOC Customer Support. The platform is distinguished by its fjord-water cooling system achieving PUE of 1.08-1.15, renewable hydropower, natural EMP protection, and capacity scaling from current operational MW to potential 200 MW across 120,000 m2 of whitespace.

Direct peers

• Hydro66: Swedish colocation operator running a repurposed hydroelectric facility in Boden/Luleå. Conceptually similar to LMD: industrial-site conversion, cold-climate free cooling, renewable grid power, and HPC / mining-grade workload focus.
• Bulk Infrastructure: Norway-based provider of data center capacity, fiber networks, and industrial real estate. Competes with LMD for Norwegian colocation and build-to-suit enterprise deals, with similar renewable power story.
• Iron Mountain Data Centers: US-based colocation operator with a portfolio that includes underground and repurposed facilities and a strong reputation for high-security, compliance-grade hosting. Closest non-Nordic analog to LMD's security-and-sovereignty positioning.
• DigiPlex: Nordic colocation specialist (now owned by IPI Partners and aligned with Stack Infrastructure) operating sustainable, carrier-neutral facilities across the Nordics. Direct competitor for HPC and enterprise customers seeking Nordic footprints.
• Green Mountain: Norwegian colocation operator that builds and operates high-security, energy-efficient data centers, including repurposed mountain/hydro-related facilities. Most directly comparable peer to LMD given shared Norwegian base, renewable hydropower sourcing, and focus on high-density HPC and government workloads.

Broad incumbents

• Digital Realty: Global hyperscale and colocation platform (parent of Interxion) with significant Nordic presence. Competes for the same enterprise and HPC customers but offers a much broader global footprint and a more standardized product portfolio.
• Equinix: Global colocation and interconnection leader with IBX facilities across Europe. Overlaps with LMD's carrier-neutral connectivity story but Equinix focuses on metro interconnection density rather than HPC density and renewable power differentiation.
• Stack Infrastructure: US-headquartered hyperscale data center platform (aligned with IPI Partners) with growing Nordic presence. Competes with LMD for large enterprise and AI/HPC wholesale deployments, but at much larger scale and broader geographic reach.

Emerging players

• Northern Data: European HPC infrastructure provider pivoting from crypto mining to generative AI cloud, with large Nordic data center capacity. Comparable business model pivot from high-density compute to AI/HPC services, and potential customer or partner overlap with LMD.
• CoreWeave: US-based GPU cloud provider purpose-built for AI/HPC workloads. Comparable buyer profile to LMD's HPC customers (needing high-density cooling and renewable power) but operates its own cloud stack rather than physical colocation.
