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: 2026-06-07.
About Western Norway
Western Norway (NO5) is the Bergen electricity price area, one of five into which Norway divides its hydropower system. Its reservoirs hold about 17.4 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.
Frequently asked questions
How full are reservoirs in Western Norway right now?
As of 2026-06-07, reservoirs in Western Norway (NO5) were 39.0% full — about 6.8 TWh of stored energy out of 17.4 TWh of usable capacity.
What is NO5?
NO5 (Western Norway) is one of Norway’s five electricity price areas, centred on Bergen. NVE publishes reservoir filling degree for each price area; there is no public per-reservoir feed, so this is the level the data is reported at.
Why energy (TWh) instead of cubic metres?
Norway’s power system is hydropower-based, so NVE measures reservoir storage as the electricity it can generate. Filling degree is usable energy in store divided by usable capacity.
