After a winter characterized by weather-related outliers of extreme precipitation and periods of very mild and windy weather, Northern Scandinavia has an extreme hydrological surplus. All three zones see a risk of spilling water during this summer season and thus bringing the current estimated water value down to near-zero levels. NO4 can store up to 3 TWh of the current 7 TWh surplus for next winter, with the rest needing to be utilized prior to the autumn culmination period, hence the low water values.
With the current significant structural oversupply, in addition to the current hydrological oversupply, a lot of renewable power is trapped in the North. Looking ahead, increased consumption alongside the increased grid capacity through the Sognefjord link from NO3 already online in 2026 can somewhat alleviate the downside risk of power prices in the Northern zones.
