Due to its windy coastal location, Schleswig-Holstein plays a special role in the energy transition. In 2016, an installed wind generation capacity of almost 3,400 MW (1,600 MW in the Dithmarschen grid area and 1,800 MW in Nordfriesland) was achieved on the west coast. In Schleswig-Holstein new regional wind plans are also in progress. By 2025, 37 terawatt hours of electricity are to be generated from renewable energies in Schleswig-Holstein. Therefore, Tennet (European TSO) proceeded with urgent necessary expansion of the extra-high voltage network between the North and Baltic Seas in 5 stages, in which the Heide West-Husum Nord line was a separate stage.
