Start of “compactLine” construction

08.10.2017

After three years of development, TSC member 50Hertz, one of the four German transmission system operators (TSOs), finalises its research on the innovative overhead line project “compactLine” with the construction of a pilot route. The test “compactLine” comprises five pylons on a length of two kilometres and sets off at the substation Jessen/Nord in the German federal state of Saxony-Anhalt, where 50Hertz can rely on safe test conditions. It is expected to go on-grid in summer 2018.

The prime objective of 50Hertz’ research activities is to provide an additional technical alternative for future overhead line projects. The pylons of “compactLine” are lower, and its corridor width is smaller in comparison to conventional lines, thus reducing the impact on nature and local residents significantly. This opens up a potential for sustainably promoting the public acceptance of grid extension measures, which is evident from a representative population survey conducted last year on behalf of 50Hertz.
