Hitachi Energy has won a major order from TenneT and TransnetBW, two of Germany’s four transmission system operators, to supply a transmission solution for the SuedLink DC4 high-voltage direct current interconnection between the north and the south of the country.

The link is one of the most important power grid and energy transition projects in Germany. It will play a crucial role in Germany’s energy transition, enabling a reduction in the use of fossil fuels and helping to further the country’s aim of achieving carbon neutrality by 2045.

The link will employ Hitachi’s HVDC Light technology. Its capacity will be 2000 MW at ±525 kV, and its length 550 km underground. It’s purpose is to send wind generated power from the north to the industrial south, or alternatively solar power from the south to the north when needed.

“SuedLink will form the backbone of the energy transition in Germany … we are now moving towards the realisation of this important power link,” said Tim Meyerjürgens, COO of TenneT.

Hitachi Energy will also supply an HVDC Light converter station at each end of SuedLink DC4. The contract includes three cable section stations to speed up fault detection in the link.

Hitachi Energy has recently won or completed orders for solutions that integrate large-scale renewables, including converter stations for the NordLink4 HVDC interconnector between Germany and Norway, the converter stations for the connection of the 900 MW DolWin5 offshore wind farm in the German North Sea, and the Kriegers Flak Combined Grid Solution which connects the German power grids with two offshore wind farms in the Baltic Sea and to Denmark.
