The South-West Interconnector is a 380 kV overhead line, constructed by 50Hertz in three sections between Bad Lauchstädt (Saxony-Anhalt) and Redwitz (Bavaria). For the 210 kilometre extra-high-voltage line, 50Hertz has budgeted investments of some 250 million EUR.
It benefits the transmission of electricity across regions, from north to south, from the eastern to the south-western Bundesländer and within Europe. This makes it a project of great regional, national and especially European importance for the durability of the power grid.
The South-West Interconnector is one of the important connections between electricity grids in Europe, and is mentioned in EU Decision no. 1364/2006/EC on trans-European energy networks, more in particular item EL.7, as the connection project Halle/Saale-Schweinfurt (DE). Accordingly, it was also included as no. 4 in the national Power Grid Expansion Act (EnLAG) of 2009, in which the Bundestag classified a total of 24 expansion projects as urgently needed for grid development.
