Description

The Ungarfeld power plant of evn naturkraft, a subsidiary of EVN AG, is a run-of-river power plant on the Kehrbach. It was built by the Wiener Neustadt municipal power station during World War I and went into operation in 1917. In 1922 the power plant became the property of NEWAG (today EVN).

A special hydraulic engineering feature of the Ungarfeld power plant is that it forms the end of a power plant chain on the Kehrbach. At the same time as the power plant was being built, the Wiener Neustadt canal was shortened by a few hundred metres. The canal now begins at the power station and is fed from the upper water. The old canal port near the main square has been drained. Today there is a small park in its place. The canal was originally fed by the Leitha. For the Ungarfeld power plant, Leitha water was also discharged into the Kehrbach via the so-called Cattlesdorf channel. This artificial channel flows into the Kehrbach in the Academy Park.

The Ungarfeld power plant is located downstream of the Akademie power plant, which was also expanded in 1917. In the Academy Park, the Kehrbach gradually changes from a cut to an embankment and leads outside the park on an embankment to the Ungarfeld power plant. The Wiener Neustädter Kanal branches off in an easterly direction from the power plant, while the Kehrbach flows northwards in the downstream of the power plant and is crossed with a canal bridge shortly before it flows into the Fischa from the Wiener Neustädter Kanal - after it turns northwards. So the hydrological situation is very interesting.

The power plant building is no longer in its original condition because the living quarters on the underwater side were destroyed by a bomb in World War II. In its place today is a small ground-level extension with an office. The machine wing has been preserved in its original condition.

In 1991/92 the power plant technology was modernized and two new submersible generator turbines with asynchronous generators were installed in place of the old turbines. The power station building was renovated. The original generator (600 kVA output), which was driven by a connecting shaft, was shut down and was preserved as an exhibit in the generator room at the time. One of the two original Francis turbines is also on display there.
