THE world’s first T-pylon, the first new design for an electricity pylon in Great Britain for nearly a century, has been erected near East Huntspill.
It will be one of 116 T-pylons along a 57km route, connecting energy to six million UK homes and businesses.
The pylons have a single pole and T-shaped cross arms which hold the wires in a diamond ‘earring’ shape. They are 35 metres high, 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.
The new pylon design was selected from over 250 designs entered into an international competition run in 2011, organised by the Royal Institute of British Architects and Government. The competition sought a new design to reduce impact on the local environment and surroundings.
Construction of the first 48 T-pylons by Balfour Beatty on behalf of National Grid began last week near East Huntspill, with each pylon taking roughly five days to build. Construction of the remaining 68 pylons north of Sandford will begin in 2022.
