Technical Description 

The annual storage power plant in Reisseck is the core piece of the three level power plant facility. In order to store the water, natural tarns have been used on the lake plateau of the Reisseck mountain.
Dams were constructed on four of these high Alpine lakes. The barrel capacity of the lakes was increased in this way from 5.4 to a total of 17.2 million m3.

Reservoirs: The six reservoirs of Großer and Kleiner Mühldorfer See, Radlsee, Kesselesee, Quarzsee and Hochalmsee lie in the area of the Zaubernock, Großes Reißeck and the Hohe Leiter, which together form the highest zone of the Reißeck group. The generating water is collected from all lakes, whose capacities were increase by barriers and dams, next to the Berghotel Reißeck, and fed from there through a headrace tunnel through the crest wall to the Schoberboden. Situated there at an elevation of 2,237 metres are the summit station of the Reißeckbahn and the beginning of the pressure tunnel, which leads to the powerhouse in Kolbnitz over a vertical difference of 1,772.5 metres. There, the water is processed in the three machine sets (Pelton turbines) of the third block.

The annual storage power plant is hydraulically connected to the daily storage at Reißeck Gondelwiese via the Hattelberg pumping station, which enables water to be pumped from the stream catchments and the Gondelwiese reservoir of the daily storage plant to the Karseen lakes located 1,200 metres higher up on the Reißeck plateau.

Hattelberg pumping station: Each of the three horizontal, eight-stage Sulzer high-pressure storage pumps, built in 1957, has a delivery rate of 450 l/sec at a pump output of 6,200 kW each.
