Nscale is planning a new data center in Harjavalta, Finland, within the Sievari industrial area, as part of its expansion into Nordic AI infrastructure. The project originates from groundwork laid by Fortum, which signed a planning reservation agreement with the Town of Harjavalta in June 2024 covering site zoning, development preparation, and grid readiness. In April 2026, the partnership advanced through a formal site securing and development agreement, with Fortum continuing to support permitting and power infrastructure while Nscale moves toward finalizing land acquisition. The facility’s capacity, layout, and construction timeline have not yet been disclosed and are expected to be determined during the upcoming design and permitting phases.
