DC Sarpsborg: Hasle, Oslo

DC Sarpsborg AS, a joint venture between Østfold Energi (66%) and Sarpsborg Municipality (34%), is developing a speculative hyperscale data center campus of up to 300 MW on a 1,781-acre greenfield site at Hasle, approximately 5 km northeast of Sarpsborg city centre and 90 km south of Oslo.

The site has a direct connection to the Norwegian national transmission grid at the adjacent Hasle 420 kV substation, with water cooling planned via a dedicated pump station drawing from the Glomma river. DC Sarpsborg holds 15-year option agreements with 13 private landowners covering the core parcels, and the formal zoning process with mandatory environmental impact assessment was initiated in December 2025, with final zoning adoption by the Sarpsborg city council expected no earlier than October 2027.
