Current spot price in northern Norway is €10.16/MWh, while it is €745.08/MWh in southern Norway (73x the price), largely due to limitations in transport networks between the electricity zones. The price in the northern zone is so low that some hydro plants have stopped producing electricity as they would be losing money at the current price level.
