EVN Schaukraftwerk Ungarfeld

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 the First World War and went into operation in 1917. In 1922, the power plant became the property of NEWAG (now EVN).

A special hydraulic engineering feature of the Ungarfeld power station is that it forms the end of a chain of power stations on the Kehrbach. At the same time as the power plant was built, the Wiener Neustadt Canal was shortened by several hundred meters. The canal now begins at the power station and is fed from the headwater. The old canal harbor near the main square was drained. Today there is a small park in its place. Originally, the canal was fed from the Leitha. Leitha water was also fed into the Kehrbach via the so-called Katzelsdorf channel for the Ungarfeld power station. This artificial channel flows into the Kehrbach in the Akademiepark.

The Ungarfeld power station is downstream of the Akademie power station, which was also extended in 1917. In Akademiepark, the Kehrbach gradually changes from an incision to an embankment and runs outside the park on an embankment to the Ungarfeld power station. The Wiener Neustädter Canal branches off from the power station in an easterly direction, while the Kehrbach flows northwards in the power station's tailwater and is crossed by the Wiener Neustädter Canal - after turning northwards - with a canal bridge shortly before it flows into the Fischa. The hydraulic engineering situation is therefore very interesting.

The power station building is no longer in its original state because the residential wing on the underwater side was destroyed by a bomb during the Second World War. In its place today is a small ground-level extension with an office. The exterior of the machinery wing has been preserved in its original state.

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 decommissioned and was preserved as an exhibit in the former generator room. One of the two original Francis turbines is also on display there.
