A new Elbe crossing between the German federal states of Schleswig-Holstein and Lower Saxony for the transport of green electricity from North to South Germany has been completed. Tim Meyerjürgens, COO of the Dutch-German transmission system operator (TSO) TenneT, together with the State Secretaries Andreas Feicht and Enak Ferlemann, the Energy Ministers Olaf Lies (Lower Saxony) and Jan Philipp Albrecht (Schleswig-Holstein), has commissioned the new power line between the substations Hamburg/Nord (near Norderstedt/Schleswig-Holstein) and Dollern (Lower Saxony).
The new 380kV line of the TSCNET shareholder consists of four sections and is a replacement of existing lines with predominantly lower voltage levels to meet the requirements of the energy transition. A total of 110 masts were built or modified and 37 temporary masts were erected on several sections of the line. Almost all of them have now been dismantled. The installation of new conductor ropes at “Elbe Crossing 2” which has the highest pylons in Europe with a height of 227 meters, was also part of this demanding grid expansion project.
Tim Meyerjürgens explained on the occasion of the commissioning: “The extension of the 45-kilometre-long power line is an important component of the energy transition. This also includes the optimisation of the ‘Elbe Crossing 2’, the main artery in the three-phase transmission grid between Schleswig-Holstein and Lower Saxony, which serves as a bridge between the two largest wind power states in Germany.” With these reconstruction measures, Tennet has quadrupled the available capacity for the transmission of wind power in this area to 9.6 GW. The transit capacity between Denmark and Germany will also be increased, which is why the new connection is of central importance not only for the energy transition in Germany, but also at European level.
