June 2025 update – close of stage 2 consultation
The second stage of consultation on our proposals for EGL 3 and EGL 4 has now closed. This stage of consultation allowed us to share updated proposals for the projects, answer questions and listen to feedback. We are grateful to everyone who took the time to provide comments.
All feedback we received as part of this consultation will be carefully considered, alongside the outputs of our ongoing technical and environmental assessments as we finalise our proposals and prepare our application for development consent.
All documents published during this stage of consultation are available to view in our Document library. To find out more about the projects, visit the Our proposals page.

About EGL 3 and EGL 4
Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) are two offshore high voltage electricity links between Scotland and England, with converter stations and associated onshore infrastructure.
EGL 3 would run from Peterhead, Aberdeenshire, to Walpole, Norfolk, and EGL 4 would run from Westfield, Fife, to a common location in Walpole, Norfolk.
EGL 3 and EGL 4 would help to meet Government targets to reduce carbon emissions, increase our country’s energy security, and carry cleaner and more affordable energy to where it is needed.
You can read more about our proposals here. You can also 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 which held its stage 1 consultation between May and June 2025, at the same time as EGL 3 and EGL 4's stage 2 consultation. Please see EGL 5's website for more information on the project.

Why we are proposing 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.
EGL 3 and 4 are key projects in The Great Grid Upgrade, which will future-proof the Grid for years to come, facilitating the transition to a clean and more affordable energy future.
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
Once we have prepared our DCO 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.
Community benefit survey
Communities should benefit from hosting new electricity transmission infrastructure. To help us deliver community benefit programmes that work for your area, we are keen to hear your views.
We want to understand what is important to you, and where community benefit funds could deliver long-lasting benefits, including through community grant schemes and investment in community groups or via regional partnerships.
