Bramford to Twinstead

A 400kV double circuit grid network reinforcement scheme, approximately 29km in length, consisting of new lattice towers, underground cabling, and associated development.

The scheme consists of approximately 18km of overhead lines (consisting of ~50 new pylons and conductors) and 11km of underground cable system (with associated joint bays and above ground link pillars).

The proposals would connect Bramford Substation in Suffolk to a new substation which is planned to be constructed to the west of Twinstead Tee in Essex.
