The company now lists the site as offering up to 430MW of capacity across 45 hectares, with a path to several hundred additional megawatts. In August 2026 atNorth signed YIT as main contractor for an additional building, FIN04A1, including mechanical, electrical, and plumbing works. YIT was also selected as contractor for a second campus building in July 2026.
Two buildings were approaching completion in March 2026, and atNorth has filed to add further data centre buildings at the Kouvola campus.
