Hohenwarte Pumped Storage Scheme

Technology Type Open-loop Pumped Hydro Storage
Rated Power 383000 kW
URL More about Hohenwarte Pumped Storage Scheme
The Hohenwarte Pumped Storage Scheme consists of two pumped storage power plants, Hohenwarte I rated at 63 MW and Hohenwarte II rated at 320 MW, and lies on the Saale River. Hohenwarte I's first turbine generator was commissioned in 1942. Two additional turbines were added in 1959. The Saale River, closed off by a dam, forms the top basin for the power plant with a length of 27 km and a storage capacity of 180.86 million m3. (This dam was primarily built for flood control.) Hohenwarte II has been in operation since 1966. With eight pumped-storage sets it is the largest hydro power plant on the Saale River. The layout of the top basin is artificial without any natural inflow with 3.02 million m³ of water. The Eichicht catchment basin is used as a bottom basin for the Hohenwarte I and II pumped-storage plants. The hydro power generating sets are installed in a powerhouse constructed in the bottom basin.
