The construction phase of the Viking Link Interconnector project, a high-voltage direct-current (HVDC) link between the UK and Denmark, has begun.

Siemens Energy Ltd has been mobilized to the site to start the construction of the first stage of works, a 2.4km long access road for the Bicker Fen converter station site.

Siemens Energy was appointed to construct the UK and Denmark converter stations on both ends of the interconnector link. UK-work started in July to build a new access road to the site. The permanent road will take nine months to complete and will enable access for the major construction equipment to the converter station and for operational vehicles to access the site once the converter station is completed in 2023. 

Viking Link project is a joint venture between National Grid Ventures, part of National Grid, and the Danish electricity system owner and operator, Energinet.

The 1.4 GW high voltage electricity interconnector will be the longest in the world when completed, stretching 765km subsea and onshore connecting from Bicker Fen in Lincolnshire, UK and Revsing in South Jutland, Denmark to enable clean energy to be shared.

“We’ve already completed the initial groundwork with archeological and ecological surveys as well as water works studies, however this is a key construction milestone for the project.  Viking Link will play a vital role in helping to decarbonise the UK’s power supply on the journey to a net zero carbon energy system. It will enable access to a cleaner greener supply of electricity, which will make energy more secure and affordable for consumers.” said Mike Elmer, Viking Link Project Director for National Grid Ventures.

Once completed by the end of 2023, the €2 billion subsea electricity cable will have the capacity to be able to supply renewable energy to power one and a half million UK homes. By 2030, 90% of electricity imported via National Grid’s interconnectors will be from zero carbon sources.
