The 380 kV Nordring Berlin connects Neuenhagen (district Märkisch-Oderland) at Berlin's eastern city limit to Wustermark (district Havelland) to the west of the capital. The line runs through the districts of Märkisch-Oderland, Barnim, Oberhavel and Havelland as well as Berlin's borough of Pankow.
For the line route, tests are being performed during the spatial planning procedure with small-scale variants to check whether an existing 220 kV overhead line corridor can be used. The 380 kv Nording Berlin will replace the existing 220 kV overhead line over a distance of approx. 80 kilometres. The extra high-voltage line with double circuit will connect the substations of Wustermark, Hennigsdorf and Neuenhagen. In addition, a four-kilometre connection with four circuits will be built for the Malchow substation.
In accordance with the principle of route bundling, the new 380 kV overhead line will follow the existing overhead lines wherever possible and run along the A10 federal motorway, also called the Berlin Ring. Preparations are currently under way to broaden the motorway to six lanes. Both projects, i.e. the 380 kV Nordring Berlin and the motorway construction work, are being coordinated by their respective developers.
The Joint Berlin-Brandenburg Planning Department focused especially on a few short sections in the area of Birkenwerder, Velten, Summt and Zeestow in its regional development assessment, which concludes the spatial planning procedure. These issues will be studied in the next planning approval procedure.
Areas of special conservation interest are the "Tegeler Fließtal" and the "Heimsche Heide", where a study will examine how these areas can be spared as much as possible or even completely by diverting the line. For certain sections, bundling with railways and distribution grids is being considered.
