Green Mountain TEL-Rjukan Data Center Campus, also known as Green Mountain TEL-Rjukan, is a data center project in Rjukan, Telemark, NO associated with Green Mountain. 29,000 square metres; 50 MW maximum site capacity; four modular buildings. Hydropower-backed campus using natural free cooling, two grid supplies and carrier-neutral fiber. 50 MW is Green Mountain’s maximum campus design. The current grid supply is described separately as two 10 MW feeds with plans to reach two 25 MW feeds; neither figure is tenant utilization.

Electric grid

Energized

Hydropower-backed campus using natural free cooling, two grid supplies and carrier-neutral fiber.

Cooling system

Operational

Cooling and efficiency claims remain limited to operator-described designs; no water use or delivered load is inferred.

Electric grid

Planned or represented

20 MW current feed total

Two 10 MW feeds are planned to expand to two 25 MW feeds; these are electrical supply, not tenant load.
