The Leitzachwerke are among the most modern pumped storage power plants in Europe. The facility is located 40 kilometers south-east of Munich in the Feldkirchen-Westerham community between the towns of Feldolling and Vagen . They are used to generate and store electrical energy and are operated by Stadtwerke München .
Leitzachwerk 1
Leitzachwerk from 1913
After the damming of the Seehamer See with two dams and the completion of the 6.7 km long supply tunnel from the Leitzach , electricity generation began in Vagen in 1913. The power plant used the 128 m difference in altitude to the Seehamer See and generated an output of 16 MW with four turbines of 4 MW each. In 1919 and 1929 the output was increased to a total of 24 MW by two turbines with five MW each. In the course of the last expansion, pumps were also installed and an underwater basin with 800,000 m³ storage capacity was created, thus converting the power plant into a pumped storage power plant . In 1929 a tunnel was also opened, which leads water from the Mangfall and Schlierach into the Seehamer See and thus increases the output.
Today's work 1
Between 1980 and 1983, the original power plant was replaced by what is now Plant 1. The new plant achieves an output of 49 MW with a pump turbine . In pumping mode, the power plant requires an output of 45.4 MW. During the renovation, the old pressure line with a diameter of two meters was replaced by a new one with a diameter of four meters and a new power house was built.

The power plant, which was built between 1958 and 1960, also uses the height difference between Lake Seehamer See and the underwater basin to generate and store electricity. The two turbines each have an output of 24.6 MW, the pumps each have an output of 18.4 MW. This plant is supplied with water via a pressure line with a diameter of four meters.
Reservoirs
Seehamer See
The Seehamer See has a volume of 6,000,000 m³, of which 2,000,000 m³ may be removed for the power plant operation.

The underwater basins have a base area of about 0.5 km² and are able to absorb the amount of pendulum water of 2,000,000 m³. The lakes also serve to drain the excess water back into the Mangfall throughout the day. In order to use the several meters difference in altitude between the reservoirs and the river for energy, the Leitzachwerk 3 was built between 1963 and 1965, which, with two Kaplan bulb turbines , achieves an output of between 0.1 MW and 0.38 MW, depending on the water level of the lakes.
Mains connection
The grid connection of plants 1 and 2 takes place at the 110 kV high voltage level in the power grid of the distribution network operator SWM Infrastruktur .
