Project information
A secure and powerful transmission grid represents not only the backbone of the Austrian energy supply, but is also a fundamental prerequisite for the further integration of renewable energy into the grid and for reaching Austrian and European climate protection goals.
In this context, the planned 380-kV line from the St. Peter node to the German border is one of the most important factors in the success of the transition to renewables. The line will connect the renewable energies of wind and water, enabling clean wind energy from the north of Europe to be conveyed to the Alpine storage power plants (green batteries). Conversely, the new line will enable optimum use of electricity generated from existing and new storage power plants, which is primarily drawn upon when there is no or little wind. Without reinforcement from the north-south interconnector between Austria and Bavaria in Germany, the feasibility of expanding renewable energy in Europe would be called massively into question. Germany’s decision to exit nuclear power also presents new challenges for the Austrian grid.
The “380-kV line connecting St. Peter to the Austrian border (Ottenhofen/Isar/Pleinting)” includes 4 systems and will run along a length of approximately 3 km in Austrian territory (= APG’s project area). The line will connect the St. Peter node, which still has to be modified, to the substations at Simbach, Ottenhofen, Isar and Pleinting in Bavaria, Germany. The new 380-kV line will also enable the existing 220-kV lines between St. Peter and the Austrian border at Simbach/Altheim and St. Peter and the Austrian border at Pleinting to be dismantled.
German transmission grid operator TenneT is in charge of the line system on German territory.

Projects of Common Interest
The projects will enable European power grids – and therefore the Austrian power grid as well – to handle increasing quantities of electricity from renewable energy sources, which will lead to a significant reduction in carbon emissions and achievement of the EU’s ambitious climate targets.

The projects receive funding from the European Union from the budget for Trans-European Networks for Energy.
