General – Interconnector Project
National Grid will partner with TenneT Germany to develop GriffinLink, a new multi-purpose interconnector (MPI) project, which could connect British and German offshore wind to both countries.
It marks a step towards a more integrated, flexible, and efficient energy system for both Great Britain and Germany, which delivers secure, affordable energy for consumers.
GriffinLink could make an important contribution to the security of supply and market integration in northwestern Europe. Cross-border hybrid energy systems such as GriffinLink make it possible to feed cleaner electricity into the grid where it can be generated and transport it exactly where it is needed.
This integrated approach allows for:
• Better utilisation of the grids results in a more efficient use of renewable energy across national borders;
• Lowering the costs involved, and the supply chain materials required and;
• A reduced impact on coastal communities and the environment.
As a ‘multi-purpose’ interconnector connecting wind in two countries, GriffinLink would be the first project of its kind in Europe and a milestone for cross-border energy security and stability.
GriffinLink would build on National Grid’s existing 7.8GW interconnector portfolio and TenneT Germany’s 23GW interconnector portfolio. With vast experience in constructing, developing, and operating interconnectors, National Grid and TenneT Germany are well placed to develop this innovative project.
It is anticipated to be operational by the late 2030s, maximising the use of offshore wind in the Northern Seas, and meeting the demand for energy being driven by the increase in electrification due to decarbonisation, data centres and AI.
