North Sea Link: The submarine connects Norway and Great Britain

October 8, 2021 – For the first time since the beginning of October, green electricity flows through the world’s longest submarine between Norway and Great Britain. The North Sea Link stretches over 720 km from the northeast of the UK via the North Sea to southwestern Norway. Over the next three months, the high-voltage direct current will increase to its full capacity of 1400 MW, which will then provide sustainable electricity to 1.4 million households.

Use renewable energy

The relationship between the two national energy markets is based on the exchange and needs of renewable energy. If British wind turbines provided too much power during storms, it would not have to be stored in Great Britain or even wind turbines would be turned off. Instead, wind energy flows to Norway, where it is used cheaply or stored in reservoirs. British wind power can be fully utilized by cheap, green energy by exporting it to Norway and Norway. On the other hand, if small wind power is available in Great Britain, Norway will provide renewable energy from hydropower.

Save carbon dioxide

On both sides, the project is seen as a technological masterpiece and a milestone on the way to CO2-Moderation was celebrated. UK-based National Grid and Norwegian system operator Stotnet have completed the submarine cable over the past six years and invested over 1. 1.6 billion. Through the North Sea Link, Great Britain aims to avoid 23 million tons of carbon emissions by 2030.

Connect Europe

However, the North Sea connection is not the first cross-border connection of renewable energy markets. A similar project between Norway and Germany was only completed in March this year. Since then, the Northern Link submarine connects the renewable energy markets of Germany and Norway. Germany also benefits from the exchange of renewable energy with Europe’s green energy storage nation.

Submarine cables such as the North Sea Link and the North Link help to exchange renewable energy across national borders and energy markets, ensuring the supply of renewable energy and thus strengthening energy transfer in Europe. jb
