GreenScale Tonstad Campus

PRJ-1286 · Site · Tonstad, Norway

Record last updated Oct 29, 2026

Scope and capacity

GreenScale’s Tonstad campus is in site preparation beside Ertsmyra in Sirdal, Norway. The operator describes a 300 MW peak-demand reservation, not IT capacity, and targets first service in 2028. Its December 2025 electrical concession requires an approved detailed plan before electrical construction and grid works before connection; it is not campus-wide building approval or evidence of energization. Sirdal’s August 2026 memorandum reported unresolved zoning appeals, with no later determination verified in this review. Current title, first-phase IT capacity and the full building-permit position remain unverified.

Electrical concession conditions · The electrical concession requires completion and commissioning by 30 June 2028. The concession holder may apply to extend that deadline. An NVE-approved detailed plan is required before electrical construction. Connection to Ertsmyra depends on necessary works by Glitre Nett and Statnett. The concession does not establish campus wide building approval or actual energization.
