View the interactive map of our proposals

Using this interactive map, you can:

View our preferred draft alignment detailing our proposed new 400 kV overhead line between the existing Norwich Main substation in Norfolk to the existing substation at Bramford, and from Bramford to the existing Tilbury substation in Essex.
