evroc Arlandastad
evroc flagship cloud and AI data center in Arlandastad. The operator’s data-centers page, read 20 October 2026, says the facility is being built and states capacity for up to 10,000 GPUs, liquid cooling and more than 150 kW per rack; no opening date is given there. On 3 February 2025 the company said it had purchased 4,890 sqm building rights, aimed to break ground in the first half of 2025, and expected operations in the latter half of 2026. It also restated an intention to invest EUR 600 million and a design of up to 16,000 GPUs. The release headline points say the facility will feature 18 MW capacity, without defining whether that is IT load or grid connection; the current data-centers page gives no MW. Commissioning is not treated as documented.
