The Höllriegelskreuth power plant is a run-of-river power plant on the Isar .

The power plant, which opened for the first time in 1894 and in its current form in 1940, is located in the northern municipality of Baierbrunn between the Buchenhain district and the Höllriegelskreuth district of Pullach in the Upper Bavarian district of Munich . The electrical output of the power plant is 3.1  MW . The operator of the power plant is Uniper Kraftwerke GmbH (formerly E.ON Wasserkraft ).

The power plant is not located directly on the Isar, but is supplied with water from the approximately 12 km long Isar works canal on the left near Buchenhain, which flows back into the Isar at the Braunau railway bridge .

To enable the excursion rafts that run from Wolfratshausen to Munich to pass through the canal, there is an approximately 100-meter-long raft slide at the power plant .

history

The power plant goes back to the initiative of the later founders of Isarwerke . In 1889, the Munich building contractor Jakob Heilmann , Wilhelm von Finck , co-owner of the Merck Finck & Co bank, and Johannes Kaempf , member of the board of directors of the Bank for Trade and Industry , later Danat-Bank, applied for a permit for a 1,000 hp hydropower plant in Höllriegelskreuth in 1890 was granted. The power plant should supply the city of Munich with electricity. Because of the "high risk", however, the city did not want to accept the offered participation or takeover of the power plant. It was therefore decided to supply the surrounding communities with electricity, starting in 1891 with Thalkirchen, which was still independent at the time, with 3 arc lamps, 1,132 incandescent lamps, three motors with a total of 14.5 HP and a heating device.

The power plant was the eighth German three-phase power plant. Isarwerke GmbH was entered in the commercial register on October 31, 1894. In order to create sales markets, the company developed an industrial area in Obersendling from 1895 , built roads, water pipes and a five kilometer long railway with a connection to Mittersendling station. In addition, the development of the industrial area Hollriegelskreuth began. As a result of the continuously increasing electricity consumption, the output of the Höllriegelskreuth hydropower plant was doubled to 1360 kW. It was thus the largest German three-phase power plant.

At the turn of the century, a coal-fired power plant with two steam engines with 1,000 and 1,100 hp was installed. In 1907 a steam turbine set with 2,400 to 3,000 kW was put into operation, which was supplemented in 1912 by a second, equally large machine set.

The original hydroelectric power station was shut down on March 26, 1940. On the same day, a new hydropower plant built in the immediate vicinity went into operation. During World War II it was heavily damaged. This hydropower plant is still in operation today.

In the post-war period, the steam power plant could only be used at part load due to insufficient coal supply. In 1950, the decision was made to replace the steam power plant with three new units, which when completed in 1956 had a total output of 66 MW. This steam power plant was shut down in 1970 and largely demolished in 1977.
