German engineering services firm Siemens has secured a contract to deliver two high-voltage direct-current (HVDC) converter stations for the first electricity interconnector between Germany and Belgium.
The contract, along with a five-year maintenance agreement, is valued at €273M and has been awarded by the German transmission system operator Amprion and the Belgian transmission system operator Elia.
The Aachen Liège Electricity Grid Overlay (ALEGrO), part of the European electricity highway system, will connect the Belgian and German high-voltage electricity systems using 90km-long underground cables. The converter stations will transform AC to DC and DC back to AC on the other side of the link.
Under the contract, Siemens will be responsible for the system design and the supply, installation and commissioning of all components for both converter stations using HVDC Plus technology.
Siemens’ CEO of the Energy Management Division Ralf Christian said: “ALEGrO will feature state-of-the-art converter technology.
“The HVDC Plus solution from Siemens assures the highest reliability and efficiency in transmitting power independent from specific weather or grid conditions. HVDC Plus masters the growing challenges from fluctuating renewables.”
ALEGrO is set to begin commercial operation in 2020.
