380 kV line St. Peter - Federal border

The project "380 kV line St. Peter – Staatsgrenze/federal border (Simbach)" covers a length of approx. 3 km on Austrian territory (=APG project area) and connects the grid knot of St. Peter, which is to adapted accordingly, to the substation of Simbach in Germany. The power line on German territory is the responsibility of German transmission grid operator TenneT.


A reliable and efficient power transmission grid is the backbone of the Austrian power supply and forms the basic prerequisite for further integration of renewable energies and the achievement of the Austrian and European climate goals.

In this context, the planned 380 kV line from the St. Peter grid node to Germany is a crucial requirement for successfully implementing the energy transmission: it combines the renewable energy sources 'wind' and 'water'. Clean wind energy from Northern Europe can thus be conveyed to the pump storage power plants in the Alps (green batteries). Conversely, the new line will enable optimal use of power from existing and new storage power plants. This power will then mainly be drawn on whenever there is no or little wind blowing. Without reinforcement of the existing transmission grid between Austria and Bavaria, the feasibility of expanding renewable energies would be called into question to a major extent. In addition, the German abandonment of nuclear energy presents new challenges for the Austrian grids.

With 4 systems, the "380-kV St. Peter – Federal Border (Ottenhofen/Isar/Pleinting) Line" will run along a length of approximately 3 km on Austrian territory (= APG project area) and connect the St. Peter grid node to be adapted with the Simbach, Ottenhofen, Isar and Pleinting substations in Bavaria. The new highly efficient 380 kV connection will thus prevent the foreseeable congestion between Germany and Austria. In addition, the new 380kV Line will also enable the dismantling of the existing 220 kV line between St. Peter and the Federal Border (Simbach/Altheim) and St. Peter and the Federal Border (Pleinting).

The German transmission grid operator TenneT is in charge of the line system on German territory.
