World’s Largest Electric Cable: Viking Link
Introduction
The world’s largest electric cable, known as the Viking Link, marks a significant advancement in global power transmission. Spanning 765 kilometers, this high voltage direct current (HVDC) interconnector links the UK and Denmark, signifying a major step in international energy cooperation and renewable energy integration.
Overview of Viking Link
- Length and Capacity: The Viking Link stretches 765 kilometers, connecting Lincolnshire in the UK with Jutland in Denmark. It can transmit up to 1.4 gigawatts (GW) of clean energy, sufficient to power approximately 1.4 million UK homes.
- Construction and Partners: A £1.7 billion ($2.15 billion) joint venture between the UK’s National Grid and Denmark’s Energinet, the Viking Link was manufactured by Italy-based Prysmian Group and installed with the help of Copenhagen-based NKT.
Specifications and Features
- Innovative Design: The single-core, mass-impregnated, paper-insulated submarine cables of Viking Link pass through British, Dutch, German, and Danish waters, showcasing a robust and efficient design.
- Comparison with Other Links: Viking Link is similar in capacity and length to the UK–Norway North Sea Link, highlighting the growing trend of large-scale international power interconnectors.
Project Development and Milestones
- European Recognition: In 2015, Viking Link was listed as an EU “Project of Common Interest”, underlining its significance in the region’s energy strategy.
- Construction Phases: The project saw the completion of its land cables and most of its dual subsea cable by 2023, with final electric testing and commissioning set to conclude by the end of the year.
Impact and Benefits
- Boosting UK’s Electricity Interconnection Level: The Viking Link will significantly increase the UK’s electricity interconnection level from its 2014 rate of 6%, enhancing the country’s energy security and integration with European energy markets.
- Economic and Environmental Gains: An analysis showed substantial societal and economic benefits from the Viking Link, including enhanced capacity for heat pumps in district heating and potential energy price reductions.
Conclusion
The Viking Link is not just a marvel of engineering but a testament to the power of international collaboration in the realm of renewable energy and sustainability. As it nears operational status, the Viking Link stands as a beacon of progress in the global transition towards cleaner energy sources.
