National Grid, TenneT Unveil 2 GW GriffinLink Linking UK and Germany's Offshore Wind

Overview

• GriffinLink is proposed as a multi-purpose interconnector that would route power from offshore wind in British and German waters to either country’s grid as needed.
• The companies describe it as the first project of its kind in Europe, combining cross-border transfer with direct connections to wind farms.
• The plan targets up to 2 GW of capacity and an in-service date in the late 2030s, subject to a future final investment decision.
• National Grid Ventures and TenneT Germany will conduct onshore and offshore studies, business-case work, and socio-economic analysis over the coming years.
• The announcement came at the North Sea Summit in Hamburg, alongside regional pledges to expand cross-border offshore wind, and follows the separate UK–Germany NeuConnect link due in 2028.
