Viking link project awarded BREEAM Infrastructure "Very Good" certification

5th June 2024, Bicker Fen, Lincolnshire – The Viking Link Converter station, part of the world’s longest land and subsea electricity interconnector, has been awarded BREEAM Infrastructure ‘Very Good’ certification in recognition of its exceptional commitment to sustainability and environmental performance. 

Viking Link, a 1.4 GW high voltage direct current electricity link between the British and Danish transmission systems, was developed collaboratively by National Grid and Danish system operator Energinet. Stretching 475 miles (765km), the interconnector connects Bicker Fen substation in Lincolnshire, UK, and the Revsing substation in southern Jutland, Denmark. 

The £1.7bn project has the ability to power up to 2.5 million homes. It is expected to deliver over £500 million in savings for UK consumers over the next decade due to the link enabling cheaper power to be imported from Denmark. By achieving ‘Very Good’, the Viking Link project demonstrates a commitment to sustainable practices and sets a new standard for infrastructure development. 

Siemens Energy, the lead contractor for Viking Link, constructed the UK converter station at Bicker Fen, which plays a crucial role in transporting power between Denmark and the UK. The company also supplied the state-of-the-art HVDC PLUS technology which has enabled the direct sharing of clean electricity between Britain and Denmark for the first time. 

By working within the BREEAM Infrastructure assessment methodology, we were able to achieve a remarkable 10,679 tonnes of carbon reduction from the baseline, the equivalent to the annual electricity consumption of around 2,000 homes. This achievement demonstrates the impact of integrating sustainability practices throughout the lifecycle of a project.
– Mark Pilling, Vice President, Grid Solutions, Europe
Siemens Energy and National Grid have embraced the flexibility of the BREEAM Infrastructure scheme, enabling sustainable innovation and impressive savings in impacts and costs. The submission was further strengthened by achieving an innovation credit for using a hydrogen fuel cell during construction, effectively reducing local pollution and overall impact. As Siemens Energy's first BREEAM Infrastructure certification, the remarkable results underline the team's commitment to sustainable practices.
– Ian Slesser, Head of BPS at the Building Research Establishment (BRE)
Supporting the decarbonisation of the UK and Denmark is one of the core reasons why we developed Viking Link in the first place, and we are delighted that it has been awarded BREEAM Infrastructure certification.
– Phillip Spain, Project Director at National Grid
