Data source: NVE — Magasinstatistikk — weekly filling degree (fyllingsgrad) and energy content (TWh) by elspot price area. Norway is a hydropower system, so storage is reported as energy, not water volume; filling degree is usable energy ÷ usable capacity. Last reading: 2026-09-06.
About Northern Norway
Northern Norway (NO4) is the Tromsø electricity price area, one of five into which Norway divides its hydropower system. Its reservoirs hold about 21.1 TWh of usable energy capacity. Filling degree is drawn down through winter and refills with snowmelt from late spring; comparing the current curve against earlier years (above) shows whether the area is running wetter or drier than normal.
