Innovation for overhead power lines

Project title: Evaluation of innovative 380 kV transmission line systems in terms of their lawfulness and effects on the landscape in various implementation areas.

Focus

  • What impact do overhead power lines have on the landscape?
  • How can the impact of overhead power lines on the landscape be mitigated?
  • Developing innovations, narrower overhead power lines
  • Legal framework

The energy transition requires expansion of the power grid, but there is a low acceptance of power masts. This project therefore aims to develop innovative systems for masts and cables in the 380 kV high-voltage range.

According to a recent survey by the BfN on environmental awareness, there is much lower public acceptance for expansion of the electricity grid than for other measures in the energy transition. The overhead power cables for expanding the transmission grid are considered particularly unacceptable. This project therefore aims to develop innovative overhead transmission systems that fit better into the landscape and can be expected to gain a higher level of acceptance. The project focuses on the construction of a 380 kV transmission system including the masts.

It also evaluates existing transmission systems in terms of their impact on the landscape and avifauna. An examination will also be made of how the transmission systems fit into the existing legal conservation framework. If it is found to be realistic to reduce the height of the masts and width of the route of existing extra-high voltage transmission lines, this raises a number of legal questions. Consequently, approval issues and responsibilities are also examined.

These findings might also enable the existing 110 kV distribution network routes and 220 kV overhead line routes to be designed to be more compatible with the landscape.

METHODS

In the first step, new, significantly lower and narrower overhead mast systems for the 380 kV level will be designed and described. Due to their smaller dimensions, these innovative overhead lines can also be used for lower voltage levels (110 kV, 220 kV) in existing transmission routes. In the second step, various versions of the innovative overhead mast systems will be visualised and their impacts on the scenery and various types of landscape and on the avifauna evaluated. In the third step an assessment will be made of how the innovative overhead pylon systems fit into the existing legal framework or how this could be expanded if necessary. The main points here are the joint use of the route by transmission and distribution network operators and on taking account of technical aspects in federal sectoral planning.
