Quick takeaways
The Viking Link subsea power cable enables the transmission of excess electricity between the UK and Denmark, promoting energy security and potentially reducing household energy prices.
Interconnectors like the Viking Link play a crucial role in transferring renewable energy, enhancing security of supply, reducing carbon emissions, and facilitating international cooperation for a more sustainable and cost-effective energy future.
Deep dives
The Viking Link: A Land and Sea Power Cable
The Viking Link is a massive land and sea power cable that connects Denmark and the UK. With the ability to switch energy in either direction, it allows for the transmission of excess electricity from one country to another. This flexibility is particularly useful during different demand patterns and enables countries to optimize their energy systems. Although security concerns exist due to sabotage risks, efforts are made to ensure proper surveillance on the cables. The Viking Link aims to contribute to energy security, promote green energy transmission, and potentially bring down household energy prices.
Interconnectors: Infrastructure for Energy Flexibility
Interconnectors play a vital role in the energy systems of countries like the UK and Denmark. They allow for the transfer of renewable energy from where it is produced to where it is needed most. By connecting markets and providing access to different types of generation, interconnectors enhance security of supply and enable the import/export of electricity during times of system stress. These interconnections contribute to carbon reduction efforts, help avoid the need for carbon-emitting generation, and facilitate cooperation among countries for a more sustainable and cost-effective energy future.
Challenges and Benefits of Interconnectors
Interconnectors, such as the Viking Link, bring both benefits and challenges. On one hand, they can help lower energy prices for consumers, reduce carbon emissions, and increase energy security. However, they are not without risks, as the recent reports of sabotage demonstrate. The industry and government need to collaborate closely to address these risks, focusing on cybersecurity and physical threats. The goal is to enhance cooperation, carbon pricing, and energy trading to tackle climate change and ensure a reliable energy supply for the future.
They are the cables that run along the sea bed to move power where it’s needed for a cheaper price.
Business Daily’s Rick Kelsey goes to the site of The Viking Link - the longest one ever built - just before it goes live between the UK and Demark.
We’ll be hearing what these cables may do for our electricity costs and how safe they are from sabotage.
Rebecca Sedler Managing Director for NG Interconnectors tells us how it will save people money, and engineer Oliver Kitching spent four weeks on the cable laying vessel at sea. We also here from the Danish engineers who often have too much power available, plus Dhara Vyas from Energy UK discusses concerns around sabotage.
