Overview – Summer 2022
We started work to build the new substation near Sandford with our contractor, Siemens, in April 2020.
The substation will be fully energised in late 2023. Located in the centre of the new Hinkley connection route, the substation will connect low carbon energy from Hinkley Point C, and will reinforce the security of the electricity network in the South West following the removal of 67 kilometres of 132,000 volt overhead wires and 249 pylons in total from the Somerset landscape.
In July 2021, we started work to modify the existing 132,000 volt power line from Weston-super-Mare. We’ve completed building nine new lattice pylons north-west of the substation towards Puxton and are working to install 700m of underground cable, which together will connect the existing Weston-super-Mare line to the new substation.
Thank you from everyone working on the project for your patience as we continue our work to deliver electricity safely, efficiently, and reliably, and support the UK’s ambition to achieve net zero by 2050.
