Wind power line SuedLink to be equipped with Siemens Energy HVDC technology
"The construction of SuedLink, the largest grid
expansion project in Germany, is crucial to the success of the energy
transition," says Tim Meyerjürgens, Managing Director of TenneT. "The
award of these converter stations is an important milestone in our efforts to
implement this system. It proves that we have managed to make important
progress on SuedLink despite difficult conditions during the COVID pandemic,"
Meyerjürgens said.
"With the award of the contract, we have taken a
decisive step closer to realizing SuedLink. Now the planning can be further worked
out in concrete terms at two starting and end points, and the preparatory
construction measures already underway at the southern end point in Leingarten,
Baden-Württemberg, can be driven forward," emphasized Dr. Werner Götz,
Managing Director of TransnetBW.
"After Ultranet and SuedOstLink, SuedLink is the third
high-voltage direct current corridor project in Germany to be implemented with HVDC
systems from Siemens Energy. We are pleased that our technology ensures that
renewable electricity can be transported to where it is needed. In this way, we
are making an important contribution to the energy transition," said
Beatrix Natter, Executive Vice President Transmission at Siemens Energy.
SuedLink is one of the largest energy infrastructure
projects in Europe. At the end points of the approx. 700-kilometer power link,
converter stations are required that can convert direct current into
alternating current and alternating current into direct current. The SuedLink
converters will be designed as self-commutated voltage-sourced converters in a modular
multilevel converter (MMC) arrangement with a rated DC voltage of ±525
kilovolts. In addition to active power, the systems can also independently
control reactive power. This allows them to respond flexibly to fluctuations in
generation and consumption in the grid and enables the low-loss transport of up
to two gigawatts of power in both directions. This output, which is equivalent
to that of two nuclear power plants, can supply around five million households
with electricity.
Siemens Energy is currently implementing ten HVDC projects
worldwide and can already look back on more than 59 successfully completed
projects.
After Ultranet and SuedOstLink, SuedLink is the third high-voltage direct current corridor project in Germany to be implemented with HVDC systems from Siemens Energy.
