EcoDataCenter's 2025 annual report states that buildings C and D at Falun were completed and commissioned, with reported site capacity of 41 MW at year-end 2025; the report does not establish that figure as IT load. Construction of buildings E and F began in 2025, with F forecast for Q3 2026 and E for the end of Q4 2026; the report's 65 MW figure is the expected total after both are completed, not confirmed current capacity. EcoDataCenter's Falun main site is an operating Nordic data center campus with heat recovery and renewable power access. The expansion announced in 2023 produced two additional wooden data center buildings and previously carried a 45 MW site target. The later annual-report figures should not be treated as proof that the E/F expansion has opened.

The 2023 release forecast first delivery in Q3 2024 and full completion in Q2 2025. Current operator material verifies buildings, not the full 45 MW as live IT capacity.

Customer deployment is distinct from facility capacity and from the wider Falun expansion.
