Key infrastructure projects for European grid development

The expansion of a future-proof and high-performance power grid is essential to optimally harness renewable energies and distribute them across Europe. Numerous key projects are driving this transformation forward, showcasing how innovative technologies and sustainable solutions are securing the energy supply of the future. This article presents key infrastructure projects that play a crucial role in European grid development.

The importance of a stable energy infrastructure 

The goals of the energy transition are clearly defined: by 2050, the European Union aims to become the first climate-neutral continent, and by 2030, CO₂ emissions are to be reduced by 55%. Achieving these ambitious goals requires new energy sources to be widely integrated into the grid, enabling the transport of vast amounts of electricity—both on land and at sea. 

While wind and solar energy already play a significant role in Europe's energy supply, their decentralised and weather-dependent generation necessitates a robust grid infrastructure to transport electricity exactly where it is needed:  

• This challenge is particularly evident in areas, where wind generation and usage is not close to each other, such as in Germany, where wind power is mainly generated in the north, whereas the highest energy demand is in the south.  
• Expanding the power grid and developing innovative transmission solutions are therefore essential to ensuring a secure and efficient energy distribution. 
  
  
  

Infrastructure for European grid development: 4 model projects

Viking Link (Denmark – United Kingdom)

Viking Link is a 1,400 MW high-voltage direct current (HVDC) interconnector that connects the British and Danish power grids. Stretching approximately 765 km, with a large portion running as a subsea cable, the project enables efficient energy exchange between the two countries. Viking Link supports the integration of renewable energy sources while enhancing grid stability. 

Südlink (Germany)

Südlink is one of Germany’s most significant grid expansion projects. This high-voltage direct current (HVDC) transmission line will transport wind power generated in the north to the energy-demanding southern regions. With a planned length of around 700 km, Südlink will play a key role in ensuring energy security and achieving Germany’s energy transition goals. 

BorWin5 and BorWin6 (Offshore Projects in the North Sea)

The BorWin5 and BorWin6 offshore grid connections are crucial projects for integrating wind power into the European electricity network. These HVDC links facilitate the transmission of offshore wind energy to the German grid, significantly contributing to CO₂ reduction and a sustainable energy supply. 

ScottishPower Green Link (Wales)

ScottishPower’s Green Link is a planned infrastructure project that will connect the power grids of Scotland and Wales. The aim is to improve the exchange of renewable energy while increasing grid stability through better interconnection of wind farms and other renewable energy sources.
