How Norway became the trailblazer for electric vehicles
HYDROPOWER
Hydropower is still the mainstay of the Norwegian electricity system. At the beginning of 2023, there were 1 769 hydropower plants in Norway, with a combined installed capacity of 33 691 MW. In a normal year, the Norwegian hydropower plants produce 136.49 TWh, which is about 88% of Norway’s total power production.
Water inflow and installed capacity determine how much hydropower the Norwegian system can produce. Inflow varies considerably during the year and from one year to another. The water inflow is highest during the spring, normally declines towards the end of summer but increases again during the autumn. Inflow is generally very low in the winter months.
Norway has more than 1240 hydropower storage reservoirs with a total capacity of 87 TWh. The 30 largest reservoirs provide about half the storage capacity. Total reservoir capacity corresponds to 70% of annual Norwegian electricity consumption. Most of the reservoirs were constructed before 1990. Upgrading and expansion of hydropower plants has
