Planning a Third Power Line in Bavaria
Tennet, the electricity grid operator, is pondering over a new project – a third major power line for Bavaria. If executed, this line will terminate in Trennfeld, Lower Franconia. Mario Meinecke, Tennet's grid development expert, discussed this proposal with the Münchner Merkur newspaper.if Tennet goes ahead with it, the line might begin operating in the mid-2030s, as per their estimation. This line could significantly increase the potential for wind power from northern Germany in Bavaria in the future.
Meinecke further elaborated that the Federal Network Agency aims to boost high-voltage direct current transmission to Baden-Württemberg from two to four gigawatts. Instead of increasing the line's capacity to Bavaria, Tennet is proposing to split this line and make one of the cables end in Trennfeld, Bavaria, to the Federal Network Agency.
The closure of nuclear power plants has led to a decline in Bavarian electricity production. However, most experts concur that electricity demand in Bavaria is projected to rise. The previously planned power lines, "Südlink" and "Südostlink," have been in the limelight so far. The first ends in Lower Franconia, and the other in Lower Bavaria. The proposed third line would complement these existing projects.
Bavarian Minister of Economic Affairs, Hubert Aiwanger (Freie Wähler), previously considered the first two lines redundant, but now calls for the third one.
The new power line suggested by Tennet could potentially increase the availability of wind energy from northern Germany in Bavaria, owing to the anticipated increase in electricity demand. This proposed line, ending in Trennfeld, could enhance Bavaria's electricity infrastructure, possibly supporting the rise in renewable energy sources.

Insights
Tennet's proposed third major power line is aside from the SuedOstLink project, which involves constructing an HVDC transmission line from Wolmirstedt, Sachsen-Anhalt to Landshut, Bavaria. Here are the essential details:
- Length and Route: The SuedOstLink spans approximately 540 kilometers, running from Wolmirstedt near Magdeburg in Sachsen-Anhalt to Landshut, Bavaria's former Isar power-plant site.
- Capacity and Voltage: The project will transmit 2,000 megawatts of electricity with 525 kilovolts voltage level and a current intensity of approximately 3,800 amperes.
- Development and Planning: The project developer, 50Hertz, oversees the northern part, while TenneT manages the southern part in Bavaria. The project involves underground cables, as standard for HVDC projects due to regulatory requirements.
- Construction Timeline: Early construction measures started in spring 2024, with broader construction plans anticipated in 2025.
The SuedOstLink aims to transport electricity from wind farms in northern Germany to the south, where the demand for a secure energy supply is increasingly required due to phase-outs of nuclear power plants and coal. This development supports the coverage of maximum load and the enhancement of energy security in Bavaria.
