The steam power plant Ebenfurth in Lower Austria was owned by the city of Vienna standing, with brown coal fired steam power plant .
Steam power plant
In 1912 the lignite mining company Zillingdorf was acquired by the Viennese municipal electricity works and a caloric power plant was built in Ebenfurth , in which its own lignite from Neufeld an der Leitha was used for firing.
Although the buildings were ready for the installation of the boiler and machine sets in 1913, the beginning of the First World War delayed completion. With four Garbe steep tube boilers and two 3,000 kW turbine sets, the Ebenfurth steam power station began operating on February 24, 1915. Initially, however, only the coal mine and neighboring towns were supplied with electricity. In 1917 a third turbine set with 12,000 hp and two further boilers were put into operation.
In 1922, three boilers and a second 12,000 hp turbine set were put into operation again. In 1924 , a 20,000 hp unit was installed to replace an 8,000 hp turbine set that had been delivered to the Simmering power plant in Vienna. With the construction of two more boilers between 1925 and 1926, the final expansion of the Ebenfurth steam power plant was achieved.
As a result of the global economic crisis , the demand for electricity decreased and since the mining of lignite became increasingly uneconomical, operations were stopped on March 8, 1934. The boiler and machine systems were sold.
In 1926, the highest level of electrical energy was generated with 117.6 million kilowatt hours. The power plant covered more than 25 percent of the energy needs of the city of Vienna.
The so-called "E-Werksiedlung" in the immediate vicinity of today's substation still reminds of the former steam power station in Ebenfurth.
Sources of supply of lignite
The Zillingdorf lignite mines, which the City of Vienna was able to acquire cheaply in 1912, were the reason for the construction of the Ebenfurth steam power station. Due to a lack of workers and pit wood, coal mining was stopped here in 1917, and the workforce was continued to work in the Neufeld opencast mine. From 1919 onwards, mining was resumed in Zillingdorf until the old opencast mine was exhausted and two new opencast mines were put into operation near Stinkenbrunn and Zillingtal. In 1925 these were closed.
In 1914 - whether before or after the start of the war it is unknown - the city of Vienna leased the lignite storage facilities in Neufeld an der Leitha, Hornstein, Stinkenbrunn, Zillingtal and Pöttsching.
The Neufeld open-cast lignite mine was shut down about 20 years ago and was under water. From November 1915 the water was pumped out and in December 1916 coal production could be started in the Ebenfurth steam power station. In 1919, the Neufelder open-cast mine was confiscated by the Hungarian councilor government, which only had around 60 percent of the coal mined here delivered to Austria. A second opencast mine in Neufeld, which was put into operation in 1920, suffered from the same problems. Only after the incorporation of Burgenland into Austria did ownership return to normal, and coal could even be delivered to the electricity works in Vienna. From 1928 there were restrictions and the no longer economical operation of the opencast mine finally led to the closure of the Ebenfurth steam power station.
After the end of coal mining, the mine was flooded again and is used for tourism as the Neufelder See .
Ebenfurth substation
To improve the supply of the network previously fed by the Ebenfurth power station, the Ebenfurth substation was built between 1934 and 1935 after the shutdown on the site of the previous power station .
Overhead line
In order to be able to feed the electricity generated in Ebenfurth into the grid of the city of Vienna, a 70 kV overhead line was built. Although this was only operated as a 35 kV line in the first few years of operation, it was the first overhead line in Austria with this capacity.
Since the delivery of the steel line masts was delayed due to the war, the line was not completed until 1916. In order to obtain the necessary copper wires, an unneeded power line between the Neubad and Leopoldstadt power stations was excavated in Vienna, the insulation was removed by hand and then reworked accordingly.
From April 1922 the partial and from 1923 full operation as a 70 kV line began.
In November 1965, the official gazette of the City of Vienna announced the sale of this line leading from Ebenfurth to the South substation in Vienna for 1,415,000 schillings.
South substation (Vienna)
From 1913 the South substation was built in Vienna-Meidling (in the course of time also: switchgear and transformer house Pottendorfer Straße , main switchgear and transformer station Pottendorfer Straße or Umspannwerk Meidling ) to feed the electricity supplied by Ebenfurth into the city's grid.
