Norsk Hydro signs new long-term wind power contract for Norwegian aluminum portfolio
Norwegian aluminum company Norsk Hydro ASA’s wholly-owned subsidiary Hydro Energi AS has signed a long-term power contract with Blakliden Fäbodberget Wind AB, a Swedish wind power company, for annual baseload supply of 0.66 terawatt hours (TWh) in the period from 2022 to 2041. . . .
The wind park has an installed capacity of 350 MW and is planned to produce around 1.1 TWh annually when finalized. . . .
Primary aluminum smelting energy—the electric power used for electrolysis by the Hall–Héroult processes—was 13,332 kWh per tonne of aluminum, according to World Aluminum. In other words, aluminum production uses a lot of electricity. . . .
1.1TWh/year works out to a capacity factor of 35.9% (for a 365 day year).
