They are the first new design for a pylon in Britain in nearly 100 years and plans are under way to install 116 new T-pylons in Somerset along a 57km route.
The T-pylons have a single pole and T-shaped cross arms which hold the wires in a diamond ‘earring’ shape. At just 35 metres high, they are a third shorter than National Grid’s traditional lattice pylons, and have a smaller footprint using less land.
The new pylons form part of National Grid’s Hinkley Connection project, a £900m investment to connect low carbon electricity from Hinkley Point C Nuclear power station.
They will run between Bridgwater and Portbury, other than through the Mendip Hills AONB where the new connection goes underground. The project also includes the removal of 249 electricity pylons between Bridgwater and Avonmouth.
