The Hohenwarte pumped storage plants consist of the two pumped storage (power) plants (PSW) Hohenwarte I and II with the Hohenwarte and Eichicht dams and the Hohenwarte II upper basin . The table on the right relates to the Hohenwarte II upper basin; the remaining structures are described in the articles on the dams concerned.
The dams and power plants belong to the Vattenfall Europe Generation .
Upper Hohenwarte II basin
The Upper Hohenwarte II basin is located south of the Eichicht dam near Saalfeld . Due to the natural conditions, the barrier structure of the upper basin consists of two structures between three hills: a 1443 m long gravity dam made of concrete and a 680 m long dam made of loose stone material.
PSW Hohenwarte I
The dam Hohenwarte is the upper reservoir of the PSW Hohenwarte I. It is with 182 million cubic meters of storage capacity, the second largest dam of the Saale cascade and in Germany the fourth largest dam . The reservoir has a length of 27 km. As a flood relief , the dam has a fixed crown overflow with seven fields. In the pumped storage power plant, two machine sets with 30 MW each can generate electricity. The lower basin is the Eichicht dam with a volume of 5.210 million m³.
PSW Hohenwarte II
The Hohenwarte II PSW was built from 1956 to 1963. The first machine set was put into operation in 1965; the last not until 1966. There are eight machines, consisting of a generator, turbine and two-stage storage pump. They generate a total of 320 MW of electrical power. The mean height of fall is 302 m and the maximum is 314.5 m. The additional flow rate during turbine operation is 134.4 m³ / s at 428 revolutions per minute; the maximum flow rate when pumping is 95.2 m³ / s. Here, too, the lower basin is the Eichicht dam.
Mains connection
The grid connection is made via the Remptendorf switchgear . The PSW Hohenwarte I is connected on the 110 kV high voltage level with the electricity network of the distribution network operator TEN Thüringer Energienetze and the PSW Hohenwarte II on the 220 kV high voltage level with the electricity network of the transmission network operator 50Hertz Transmission .
