These will carry low-carbon energy between Hinkley Point C to Seabank power station, providing electricity to six million homes and businesses in the South West of England. The last of the T-structures' 232 diamond-shaped insulators – which hold the high-voltage conductors in a diamond 'earring' shape – was recently lifted by crane into place on a T-pylon between Yatton and Kenn in North Somerset by National Grid and principal contractor Balfour Beatty. T-pylons are quicker to erect than traditional lattice pylons, and 47 more T-pylons were completed – including installation of the conductors – by the end of 2022. 36 new T-pylons between Woolavington and Loxton were energised in early 2023, meaning high voltage electricity is now running along the new T-pylons, through cables under the Mendip Hills Area of Outstanding Natural Beauty and via the newly built substation at Sandford. At the same time work began to build the 68 T-pylons running north of Sandford substation to Portbury.
