Hydropower accounts for 99% of all energy production in Norway, making it by far the most important source.
Hydropower provides renewable energy, and is an environmentally friendly way to produce the electricity the country needs.
Hydro has 20 power plants in Norway - some of them among the nation's largest. The power plants we own are in the counties of Sogn and Fjordane, Hordaland, Rogaland, Vest-Agder and Telemark. We are also co-owners of several other plants.
Norway is one of Europe's leading hydropower countries. This is a result of our many mountains and lakes, in addition to our climate with high rainfall.
Hydro is Norway's second largest producer of hydroelectric power. Every year we produce around 10 terawatt hours (TWh) of hydropower. By comparison, this is roughly the same amount of electricity used by the entire city of Oslo in one year.
Or to put it another way - Hydro's production of hydroelectric power would meet the annual electricity needs of 625 000 households.
It is also enough to produce 800 000 tonnes of aluminium!
Hydropower generation provides the power supply we need for our aluminium plants, and we also buy and sell power through NordPool, the Nordic power exchange.
When and where?
Hydro has 20 power plants spread across the country in the counties of Sogn and Fjordane, Hordaland, Rogaland, Vest-Agder and Telemark. We have produced hydro power for over 100 years.
Highlights from our history:
Construction of Svelgfoss, Hydro's oldest power plant, started in 1906. Svelgfoss was originally built to provide electricity to Hydro's first potassium nitrate plant in Notodden.
In 1911, the Vemork power plant in Rjukan was completed and was the world's largest at that time.
In 1948 the Skafså power plant in Telemark was built in conjunction with the start of magnesium production in Herøya
During the period 1960-1963, the Sundsfjord power plant was put into operation to provide power for ammonia and fertilizer production in Glomfjord.
From 1963 to 1968, Røldal-Suldal was developed to provide electricity to the aluminium smelter in Karmøy. It was the largest hydropower plant construction project in Norway until then.
In 1986 Hydro took over Årdal and Sunndal Works including its Tyin and Fortun power plants.
In Hydro we are working to ensure hydropower generation in the future. Although many of the resources suitable for hydropower production are already in use, we continuously develop and upgrade existing power plants to achieve more efficient operations.
