The west coast line from the Danish border to Brunsbüttel, which is important for the energy transition, officially went into operation on Saturday.
At a celebration near Wöhrden near Heide with the mayors of the 48 neighboring communities, the northern program director of the network operator Tennet, Klaus Deitermann, emphasized the importance of the line: "With the west coast line, our Tennet team now has the second one - after the central axis along the A7 Core project of the energy transition in Schleswig-Holstein from the Elbe to the Danish border completed on time." It is already clear that these lines make a decisive contribution to the fact that more and more wind turbines are turning here, he said. “Schleswig-Holstein is therefore the only federal state in which the high-cost forced shutdown of onshore wind turbines is decreasing.”
The west coast line is 140 kilometers long and has a voltage of 380 kilovolts (kV). It is built as an overhead line and is used to absorb large amounts of wind power from the west coast. Electricity has been flowing through the line since the end of September. After the symbolic commissioning, interested parties were able to find out more about the system and its role in the energy transition at an open day at the Heide substation.
In recent years, more wind power has often been produced in the north than consumed. This led to expensive system shutdowns. One goal of the energy transition is to bring wind power from the coast to large consumers in western and southern Germany. Construction has also begun on the 700-kilometer-long SüdLink line, for which a tunnel is being drilled under the Elbe.
