Substation Wolmirstedt
At the substation in Wolmirstedt you will find an important electric node in the transmission system connecting Eastern and Western Germany. In the year 1989 the first 380 kV transmission line connected Helmstedt with Wolmirstedt. This transmission line was the first part of the connection between Helmstedt and Berlin. Furthermore, in the past the longest 380 kV transmission line with a length of 287.4 km was connected to the substation. During the tour at the substation you will visit a control room, which is now out of order.
In the future the USW will be connected via an HVDC link to Isar in Bavaria. The link named DC5 will have a total length of 580 km and a nominal power of 2 GW. The main task of the link will be the transmission of electricity from regions with a high penetration of renewables in Eastern Germany to the load centers in the south. The launch is planned for 2025.
