Siems is a part of Lübeck. In Lübeck-Siems there was until the beginning of the ninties a coal fired power plant, which was knocked down, because it did not meet the econonomical standards of our days. Today there is the switchyard, at which the 380kV-line running to the static invertor station Lübeck-Herrenwyk ends. This powerline should be built further toward the nuclear power station Krümmel, but because of difficulties for getting the necessary permissions, construction did not start until now, so the electric power, which is imported from Sweden via "Baltic-Cable" has to be transformed down to 110kV, what increases losses and which allow an operation of "Baltic-Cable" with a maximum power of 372 megawattts, instead of 600 megawatts as it is designed for. From the substation Lübeck-Siems also two 110kV-circuits for three-phase AC run to the 110kV/20kV-substattion Lübeck-Herrenwyk. This substation is on the area of the static invertor plant of Baltic-Cable, but there is no 380kV/110kV-transformer, so its fed is done from Lübeck-Siems. The circuits of the 110kV-powerline from the substation Lübeck-Siems toward the substation Lübeck-Herrenwyk are laid on the same pylons as the 380kV-circuits from Lübeck-Siems toward the static invertor plant Lübeck-Herrenwyk, whereby the 110kV-circuits are on the lowest and the 380kV-circuits on the middlest and the obermost crossbars of the used pylons.
