Building T-pylons between Bridgwater substation and Loxton
In May 2020, we started work to build T-pylons between Bridgwater substation and a new cable sealing end compound (CSC) at Loxton, where it will join to the underground cables we’re building through the Mendip Hills.
We’re using T-pylons for most of the route – the first new design for pylons in this country for almost a century. It has a single pole and T-shaped cross arms which hold the wires in a diamond ‘earring’ shape. It is around 35 metres high; about a third shorter than traditional 400,000 volt steel lattice pylons. It also has a smaller footprint and will use less land.
We expect to start erecting the T-pylons across the southern section of the Hinkley Connection Project route from September 2021.
We’ve appointed Balfour Beatty as the principal contractor for this stage of work and we expect to complete construction of the T-pylons by the end of 2022.
We recognise that our construction activity impacts local communities. We are working with our contractor to limit that as much as possible.
We’ve completed all the driven piling for this section of the route. We have three foundations to build using mini-piling techniques and we expect this work to be completed in the autumn.
Our agreed standard working hours are between 7am and 7pm Monday to Friday and 8am to 5pm on weekends.
