Spatial planning success for DolWin4 and BorWin4

The German Office for Regional State Development Weser-Ems has decided that a spatial planning procedure in the southernmost section of Amprion's DolWin4 and BorWin4 offshore projects is not necessary. Amprion was able to demonstrate in a detailed feasibility study that laying the underground cables is compatible with the objectives and principles of spatial planning.

For this, the transmission system operator has different route variants for the southernmost approval section of the DolWin4 and BorWin4 offshore connection lines developed and studied. After careful consideration of spatial planning, environmental and technical criteria, the approximately ten kilometer long preferred variant was determined. Due to the pandemic restrictions, the public authorities were involved in writing, digitally or by telephone.

“We were able to avoid delays thanks to the open and good cooperation and the pragmatic action of all those involved under the leadership of the Office for Regional State Development Weser-Ems. This is a good example of how network expansion for the energy transition continues despite the corona pandemic," said Eric Zieschang, project manager at Amprion.

Due to the elimination of the spatial planning procedure, Amprion can now start preparing the planning approval procedure in the section between Wietmarschen and Lingen earlier than planned. The Dortmund company is expected to start submitting the necessary application documents in the approval process at the end of 2022.

"Now that the spatial planning aspects have been clarified, we want to create opportunities for citizens to participate in the course of the year," says project spokesman Stefan Sennekamp. "We hope that this will provide valuable information for further planning."

The DolWin4 and BorWin4 offshore grid connection systems,are scheduled to go into operation in 2028 and 2029. From the North Sea wind farms, the cables initially run 50 and 130 kilometers at sea. It passes under the island of Norderney and reaches the coast in the Hilgenriedersiel area. Amprion wants DolWin4 and BorWin4 between Emden and Wietmarschen (Grafschaft Bentheim) to run with the direct current connection A-Nordbundle, another underground cable project by the transmission system operator. The aim is to minimise interventions in the soil and landscape, the impact on residents and the costs through joint construction work.

In the Wietmarschen area, the paths of the three projects separate again. From there, the two offshore projects in the so-called southern section will runs around ten kilometers towards the Hanekenfähr substation in Lingen, where Amprion will connect it to its transmission network.
