Germany’s Federal Network Agency (Bundesnetzagentur) has published its Electricity Network Development Plan 2023-2037/2045 considering expanding the existing electricity transmission grid with around 4,800 km of new lines and reinforcing around 2,500 km of existing connections to achieve a climate-neutral electricity system by 2045.
The Federal Network Agency has only defined the start and end points of the lines and it will eventually determine the exact routes. It considers 35 additional line projects the North Sea and Baltic Sea to be necessary by 2045, which could connect up to 70 GW of power from offshore wind projects to the mainland. The BNetzA has announced plans to build five new high-voltage direct current (HVDC) transmission connections, each with a capacity of 2 GW: DC32 from Schleswig-Holstein to Mecklenburg-Vorpommern, DC35 from Lower Saxony to Hesse, DC40 from Lower Saxony to Saxony, DC41 from Lower Saxony to Baden-Württemberg, DC42 from Schleswig-Holstein to Baden-Württemberg), and the P540 alternating current project to supply energy to Bavaria.
There are four transmission system operators (TSOs) each covering different regions of Germany: Amprion, TenneT, TransnetBW and 50Hertz Transmission. The German transmission network reached around 35 000 km at the end of 2022.
