About South-East Norway
South-East Norway (NO1) is the Oslo electricity price area, one of five into which Norway divides its hydropower system. Its reservoirs hold about 6.0 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.
