March 2026 update
We have now considered all the feedback we received during our Stage 2 consultation in spring 2025. This feedback, along with local surveys and assessments, has helped to refine our proposals for EGL 3 and EGL 4. This includes taking forward options for our proposals in the Walpole area and identifying some additional land required to build the Projects.
Our work over the coming months will inform the final plans for the Projects, which will form part of our application for development consent later this year. You can find further information on the work being undertaken in our FAQs and March 2026 Community Update in our Document library.
About EGL 3 and EGL 4
Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) are two primarily marine high voltage electricity links between Scotland and England.
EGL 3’s subsea cables would run from Aberdeenshire and EGL 4’s from Fife before coming onshore at Anderby Creek on the Lincolnshire coastline. From here, the cables would be buried underground and run south to West Norfolk, where they would connect into the electricity network via a new substation in the Walpole area.
We have held two stages of public consultation on EGL 3 and EGL 4. Our Stage 1 consultation took place in 2024 and helped to inform the proposals we shared at our Stage 2 consultation in 2025. The feedback we received from local communities has helped to inform our proposals for the Projects.
All the documents published we have published to date are available to view in our Document library. You can read more about our proposals, and view our onshore proposals on our Interactive map.
EGL 3 and EGL 4 are separate to National Grid Electricity Transmission's (NGET) Eastern Green Link 5 (EGL 5) project. Please see EGL 5's website for more information on the project.

Why we are proposing to build EGL 3 and EGL 4
EGL 3 and EGL 4 would both play an important role in building a more secure and resilient future energy system by reliably transporting electricity generated in Scotland, particularly from offshore wind, to the Midlands and South of England.
The Projects form part of The Great Grid Upgrade, the largest overhaul of the electricity grid in generations. They will help strengthen energy security by transporting home-grown electricity to where it is needed.
Seeking consent for EGL 3 and EGL 4
EGL 3 and EGL 4 are projects of national significance. These types of projects require a special type of planning permission to be built, known as a development consent order (DCO).
We will be seeking consent for the English elements of both EGL 3 and EGL 4 via one application to the Planning Inspectorate for a DCO. Although EGL 3 and EGL 4 are independent of one another, in effect separate projects, due to their ultimate common connection point in England (the proposed new Walpole B substation) we decided to develop them in parallel. In addition to enabling one DCO application, this coordinated and co-located approach to their routeing and siting provides the opportunity to potentially reduce the extent of community and environmental impact.
EGL 3 and EGL 4 in Scotland and Scottish waters
NGET is jointly developing EGL 3 with Scottish and Southern Electricity Networks Transmission (SSEN Transmission) and EGL 4 with SP Energy Networks. SSEN Transmission and SP Energy Networks are responsible for obtaining consent for EGL 3 and EGL 4 in Scotland and Scottish waters.
Visit SSEN Transmission’s EGL 3 website here and SP Energy Network’s EGL 4 website here here for more information.
Our DCO application
We are currently working to finalise our plans for EGL 3 and EGL 4 for our application for a DCO. Once we have prepared this application, we will apply to the Planning Inspectorate, seeking consent for EGL 3 and EGL 4. Our submission will include a consultation report, showing how we have taken account of feedback received from communities and stakeholders at all stages of consultation.
