National Grid and Danish system operator Energinet have named the suppliers for the new interconnector between Britain and Denmark.
The 1.4GW ‘Viking Link’ is the longest interconnector in the world at 472 miles and will enable the sharing of renewable energy between the countries, National Grid said. It will stretch from the Lincolnshire coast to Western Denmark.
Three contracts have now been awarded totalling £990 million.
Siemens is to supply and install equipment for two converter stations in Lincolnshire, UK and Revsing, Denmark. Prysmian Powerlink S.r.l and NKT HV Cables AB are to manufacture and install two parallel high voltage direct current cables.
The interconnector is to move from development into construction, with the aim for it to be completed by the end of 2023.
Jon Butterworth, chief operating officer for National Grid Ventures, said: “Viking Link will play a vital role in helping to decarbonise the UK’s power supply on our journey to a net zero carbon energy system. Interconnectors like Viking Link enable us to use every spare electron, meaning consumers get access to cleaner, cheaper and more secure electricity.”
