About Lefdal Mine Data Center

Lefdal Mine Data Center operates inside a former mine near Måløy and is expanding data halls across a six-level, 75-chamber campus. The site reports 10 MW in operation, 20 MW reserved for customers, 80 MW available power and up to 200 MW potential, alongside fjord-water cooling and renewable electricity.

Operating mine campusOperational

Shared mine campus; individual customer halls are deployments, not separately named public facilities.

80 MW available-power expansionPlanned

Electrical availability; 20 MW was reported reserved for current customers and should not be conflated with live IT load.

Continuous customer-hall buildoutOperational

Customer-triggered halls averaging about 700 m² are built within the mine.

Full mine potentialPlanned

Ultimate physical and electrical potential, not delivered capacity.

Infrastructure

Electric GridReported Context

10 MW in operation

Current HPC page statement; distinct from 20 MW reserved and 80 MW available electrical power.

Electric GridReported Context

20 MW reserved

Reserved for current customers; does not prove simultaneous operating IT draw.

Electric GridOperational

80 MW available

Available electrical capacity after a 60 MW expansion from 20 MW.

Electric GridReported Context

80 MW level capacity

Level 3 design statement; not treated as additional to the campus's 80 MW available power.

Electric GridPlanned Or Represented

200 MW potential

Ultimate mine-campus potential; not delivered or reserved capacity.

Electric GridOperational

132 kV

Direct connection to the regional grid through operator-owned transformers.

Electric GridPlanned Or Represented

200 MW

Last-mile grid reinforced for 200 MW with separated entries; transformer installation remains modular.

Cooling SystemOperational

90 MW cooling

Twelve modular 7.5 MW heat exchangers on Level 3 total 90 MW cooling.

Cooling SystemPlanned Or Represented

200 MW redundant cooling

Next cooling level is intended to support 200 MW redundant capacity.

Cooling SystemReported Context

8 degrees C

Year-round seawater source for heat exchangers.

Cooling SystemReported Context

100 meters

Redundant piping draws fjord water from about 100 m depth.

Site FacilityPlanned Or Represented

1.08 PUE lower bound

Operator range is 1.08–1.15 depending on cooling technology, UPS configuration and scale; not an observed annual average.

Site FacilityPlanned Or Represented

1.15 PUE upper bound

Upper bound of the operator's configuration-dependent PUE range.

Cooling SystemReported Context

50 kW per rack up to

Air-cooling capability; direct liquid and immersion can support higher densities but no normalized ceiling is imported.

Cooling SystemReported Context

0 WUE

No evaporative cooling; operator reports WUE zero. Treat as claimed design/operation metric, not independently measured.
