Building T-pylons between Bridgwater substation and Loxton

In September 2021, National Grid started erecting the world’s first T-pylon structures across the southern section of the Hinkley Connection Project route between Bridgwater substation and Loxton.

The new T-pylons being constructed between Bridgwater substation and the new cable sealing end compound at Loxton will join to the new underground cables through the Mendip Hills AONB, which will run into the new substation at Sandford.

In January 2022, our contractor Balfour Beatty began hanging the wires (conductors) between the new T-pylons that will carry low-carbon energy from Hinkley Point C and other sources. Starting at the new T-pylon north of Woolavington, the wiring will progress in sequence along the new connection route.

Where the wires cross over roads, we are erecting scaffolding and using controlled lifting systems to hang the wires. To keep everyone safe while we work on the highways, we put up temporary traffic lights and close some roads for a short time. We put up advance notice signs to let local road users know of any roadworks and traffic management in the area.

We expect to complete construction of the T-pylons and the wiring work across the southern section of the new connection route by spring 2022.
