Data Tank Utajärvi Campus

PRJ-1314 · Site · Utajärvi, Finland

Record last updated Oct 29, 2026

Scope and capacity

Data Tank’s proposed 200 MW Utajärvi campus at Mustikkakangas comprises four planned halls; the capacity basis is not explicitly verified as IT load. October 2026 announcements report preparatory works starting under NYAB, with later phases requiring separate agreements and phased completion targeted by end-2028. The developer reports a binding grid agreement. Permit 26-0014-RL requires acoustic compliance evidence before partial-final or final inspection and a special fire inspection requested before use. Municipal approval of a 26.39-hectare lease arrangement does not establish signature or ownership. The reported €2 billion investment intention is not verified financing.

Reviewed ut works scope context · The municipality’s October 9, 2026 reproduction of NYAB’s announcement reports a signed agreement with NYAB Finland Oy for first stage site preparation and infrastructure works, with options to expand preparatory works. Work was to start immediately; contract value was undisclosed. NYAB’s involvement in later implementation phases remained under negotiation and required separate agreements—not a whole campus general contractor award. An October 15, 2026 municipal update reports that construction works had begun and gives phased completion by the end of 2028 as a target. Read alongside the October 9 announcement, the verified signed contract scope is preparatory and infrastructure works; the update does not establish completed halls, energized service or contracted later phases.

Reviewed ut permit conditions context · Permit 26-0014-RL requires a measurement report by an independent qualified acoustics professional demonstrating compliance with the stated maximum 45 dB average sound level criterion, submitted with a compliance statement before partial final or final inspection. A special fire inspection must also be requested before use. These are permit conditions, not evidence that tests or inspections passed; no measurement duration or location is inferred.

The exact finality date is not established here, so no calendar expiry date is inferred.
