Our proposals
This page presents our detailed proposals for EGL 3 and EGL 4, as set out at our stage 2 consultation in 2025. This consultation has now closed and we will consider all feedback we received as we finalise our proposals.
The key onshore and offshore elements of our proposals in England and English waters are:
- Offshore high voltage direct current (HVDC) cables. In English waters, EGL 3's cable would be approximately 436 km long and EGL 4's would be approximately 425 km
- Transition joint bays to connect our offshore and onshore HVDC cables, located onshore near to our proposed cables landfall at Anderby Creek on the Lincolnshire coastline
- Underground HVDC cables running together for approximately 100 km from the joint landfall at Anderby Creek to the EGL 3 and EGL 4 converter stations in the Walpole area, West Norfolk
- Two converter stations in the Walpole area with one converter station for EGL 3 and one for EGL 4
- One substation in the Walpole area, called Walpole B, where both EGL 3 and EGL 4’s Walpole converter stations would connect to and then onto the electricity transmission network (this substation is also jointly proposed as part of NGET's Grimsby to Walpole project)
- Onshore underground high voltage alternating current (HVAC) cables that would connect the converter stations into the substation
- Supplementary works to the existing 400 kV overhead line to enable a connection with the new Walpole substation.
Sufficient land would be required to build EGL 3 and EGL 4 and to reduce the potential impacts of the projects, including:
- temporary land for construction activities including work areas for construction equipment and machinery, site offices, welfare, storage, access and drainage
- land required for mitigation, compensation and enhancement of the environment as a result of the environmental assessment process, and for the purposes of delivering biodiversity net gain, for example by landscaping and planting.

EGL 3 and EGL 4’s timeline
What’s happened so far?
In Spring 2024, we held our first stage of consultation on our early proposals for EGL 3 and EGL 4. Feedback from this consultation helped to further develop our proposals.
During our second stage of consultation, held between May and June 2025, we presented and sought feedback on our detailed proposals for EGL 3 and EGL 4. This included where we proposed to build the new infrastructure and what we should consider as we further develop our proposals.
What’s happening next?
Following the close of this consultation, we will take the time to carefully consider all comments received alongside the outcome of ongoing technical and environmental assessments as we look to finalise our proposals and prepare our application for development consent.
During this time, we will also:
- continue our discussions with landowners and people with a legal interest in land
- continue working with local authorities and other stakeholders
- carry out any further technical studies and surveys along the route
- provide updates to those who have asked to be kept updated on our proposals via email. You can register for these updates here.
