Overview – Autumn 2024

The construction of a new substation at Shurton next to Hinkley Point C, where the new power station will connect into the UK electricity network, was completed and energised in June 2022. 

Work on the connecting electricity lines into Shurton substation from the existing network is also nearing completion. This involves the alteration, testing and commissioning of three existing overhead electricity lines in the area.

Six existing pylons have been removed and 13 new pylons have been built, including the installation of the conductors (wires) in a process known as stringing. 

The remaining activity is to complete the upgrading the existing overhead lines from 275,000 volts to 400,000 volts and connect into the southernmost section of new T-pylons at Horsey Levels, north of Bridgwater. 

This connection will be via a new nine-armed junction pylon. In addition, at Horsey a new underground cable has been installed and energised. The new cable connects Shurton substation to Bridgwater substation. Installing the underground cable frees up space for new overhead lines into  connect to the same junction tower.

Thank you from everyone working on the project for your patience and understanding as we progress with this important work to connect six million homes and businesses to new sources of homegrown, low carbon energy, and help the UK meet its net zero ambitions.
