Hohenwarte I Pumped-storage Power Plant

History and characteristics 

A run-of-the-river machine set composed of a generator and turbine, which started operations in 1942. Two pumped storage sets followed in 1959 and increased the installed capacity to 64 megawatts (MW).

Hohenwarte dam, completed in 1941, serves as its upper reservoir. The 75 metre high dam was primarily constructed for flood protection and blocks a 27 kilometre long lake. The dam can hold around 181 million cubic metres of water. With a capacity of around five million cubic metres of water, Eichicht dam acts as its lower reservoir. It is also the lower reservoir for Hohenwarte II pumped storage plant.
