The substation in Pleinting near Vilshofen is one of the central hubs of the Lower Bavarian power supply, for which TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), is responsible. Also in terms of the energy transition and cross-border electricity exchange, the substation close to the Austro-German border is significant. This applies in particular to the transmission of surplus electricity from Lower Bavarian solar power generation and for the connection of Austrian pump storage power plants to the German grid.
A total of three new transformers will be installed in Pleinting, the first of which was delivered already in February 2017. The second transformer, manufactured in the Dutch town of Nijmegen, now has arrived at a nearby train station. On 6 August, the 286-tonne transformer will be delivered to the substation with a heavy-duty road transportation unit of around 45 meters in length and a total weight of 500 tonnes. The following assembly work at the substation will probably take three months.
After commissioning, the transformer will have an operating weight of 417 tonnes. It also offers an extended scope of possible applications, as it can be switched over on the high-voltage side. This means that the transformer works between the 380kV and 110kV voltage levels as well as between 220kV and 110kV. Thus it can immediately be integrated into the existing 220kV systems of the Pleinting-Pirach power line. After the completion of the planned 380kV Pleinting-Pirach line, the transformer will subsequently supply the region on this higher voltage level. By 2020, all modernisation and extension works in an around Pleinting are expected to be completed.
