Summary

atNorth announced in February 2026 a 300 MW campus, SWE04, at Hamre Industrial Park in Långsele, about 7 km west of Sollefteå in northern Sweden, on a zoned plot it describes as 50 hectares, with operation expected in the first half of 2028. In June 2026 it published a consultation document for an environmental permit application to the Land and Environment Court, describing three main buildings on a property of about 16 hectares, 145 backup generators running on HVO or similar fuel with about 1,200 MW of combustion input, and a planned grid connection agreement with E.ON. Investment has not been disclosed.

Evidence

Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
