We are seeking your views on our proposals to reinforce the electricity transmission network between the existing Bramford Substation in Suffolk, and Twinstead Tee in Essex. The proposed reinforcement is around 29 km and includes building new pylons, some underground cables and a 'grid supply point' substation. We would also take down around 27.5 km of existing pylons. Our proposals include:
around 19 km of new 400 kV overhead lines
around 10 km of new 400 kV underground cables
four cable sealing end compounds to connect overhead line and underground cable sections together
removal of around 25 km of existing 132 kV pylons between Burstall Bridge and Twinstead Tee
removal of around 2.5 km of existing 400 kV pylons south of Twinstead Tee
a new grid supply point substation at Butler's Wood, to connect the local distribution network into the National Grid
