The pumped storage power plant Erzhausen in Lower Saxony was commissioned in 1964 after a ten-year construction phase by PreussenElektra (later called E.ON). At the beginning of 2009 Statkraft took over the pumped-storage power plant Erzhausen which has an installed capacity of 220 MW. The yearly electricity generation is variable and dependent on the electricity demand.

The Erzhausen pumped storage power plant works with four Francis-Spiral turbines and is primarily used for peak power needs as well as to support the power frequency.
