Our proposals

The key onshore and marine elements of our proposals in England and English waters are: 

• Subsea 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 subsea and onshore HVDC cables, located onshore near to our proposed cables landfall north of Anderby Creek on the Lincolnshire coastline
• Underground HVDC cables running together for approximately 100 km from the joint landfall north of 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.
