Siemens Converter Stations for Viking Link Interconnector

Siemens has been awarded a contract to deliver two converter stations for Viking Link, the first high-voltage direct-current (HVDC) interconnection between Great Britain and Denmark.

Viking Link interconnector is being jointly developed by National Grid Ventures (Great Britain) and Energinet (Denmark) via National Grid Viking Link and Energinet Eltransmission.

The order comprises a 1,400-MW converter system for DC voltage of ± 525 kilovolts (kV) using HVDC Plus technology. The two converter stations – one in Bicker Fen in Lincolnshire (Great Britain), the other in Revising in southern Jutland (Denmark) – will be linked by a 767-kilometer-long DC power cable passing through the North Sea.

Siemens will be responsible for the overall system design, supply, installation, and commissioning of the converter stations.

Scheduled to begin commercial operation at the end of 2023, Viking Link will be one of the world’s longest DC electricity interconnectors.
