HVDC Light® transmission system will transfer vast amounts of renewable energy for up to 5 million households and help Germany achieve its 2045 carbon neutrality goal
Dubai; August 09, 2022 - Hitachi Energy, a global technology leader that is advancing a sustainable energy future for all, today announced it 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 (HVDC) interconnection between the north and south of the country.
SuedLink DC4 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 the country achieve carbon neutrality by 2045.1
Using Hitachi Energy’s HVDC Light® technology, SuedLink DC4 will transfer up to 2,000 megawatts of emission-free electricity, enough to power 5 million German households.2 The link will efficiently transmit electricity for 550 kilometers underground, at ±525 kilovolts, sending wind power from the north to the industrial south, or alternatively solar power from the south to the north when needed.
“We are proud to play a crucial role in this very important investment in Germany’s transition to renewable energy and carbon neutrality,” said Niklas Persson, Managing Director of Hitachi Energy’s Grid Integration business. “HVDC Light is the enabling technology for large-scale transfers of renewable energy, both onshore and offshore.”
“SuedLink will form the backbone of the energy transition in Germany. With the award of the DC4 high-voltage direct current system to Hitachi Energy, we are now moving towards the realization of this important power link,” says Tim Meyerjürgens, Chief Operations Officer of TenneT.
Hitachi Energy will supply an HVDC Light converter station at each end of SuedLink DC4 to convert AC power from the transmitting grid to DC for delivery through the link, and back to AC for transfer to the receiving grid. The contract includes three cable section stations to speed up fault detection in the link.
As part of its long-term commitment to Germany’s energy transition, Hitachi Energy has recently won or completed orders for solutions that integrate large-scale renewables3. These include the converter stations for the NordLink4 HVDC interconnector between Germany and Norway, the converter stations for the connection of the 900-megawatt DolWin5 offshore wind farm in the German North Sea, the Kriegers Flak Combined Grid Solution which connects the German power grids with two offshore wind farms in the Baltic Sea and Denmark, and power quality solutions to enable more renewable energy to flow from north to south Germany.
