GERMANY — Siemens Energy will supply HVDC technology with voltage-sourced converters (VSC) for 50Hertz and TenneT’s SuedOstLink HVDC highway.

To ensure a continued reliable supply of energy in Southern Germany, transmission system operators 50Hertz and TenneT are planning to build the SuedOstLink electricity highway. It will transport excess energy from northern Germany and ensure that green electricity can be supplied to the South.

Siemens Energy will deliver the converter technology that will enable the low-loss transport of electricity over more than 310 miles.

The converter stations will be built at Wolmirstedt in Saxony-Anhalt and near Landshut in Bavaria. The energy will be transported to the south via 525 kV underground cables.

Up to 2 GW of electricity can be transported in both directions to flexibly react to fluctuations in electricity demand and supply. The transmission capacity will be sufficient to supply more than 4 million households with electricity.

 “If we want to exploit the full potential of renewable energies and thus also of the energy transition, the transmission networks must be expanded accordingly,” said Tim Holt, member of the Executive Board of Siemens Energy. “We are pleased to be able to make an important contribution to the European energy transition with SuedOstLink."

The HVDC link will include Siemens Energy’s HVDC technology with VSCs based on modular multi-level converter (MMC) technology.
