Shurton substation

Overview – Winter 2022

Our contractor, Morrison Energy Services, is continuing works to connect Hinkley Point C and the new Shurton substation to the electricity network. This work is an important step forward in helping us get ready to carry the high-voltage electricity from Hinkley Point C onto the network.

We recognise that our construction activity causes local impact and work with our contractors to limit that as much as possible.

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.

Projects timeline

Mid 2019 to mid 2023

 

Build Shurton substation

What we're doing:

  • Building a new substation within the boundary of the new Hinkley Point C power station complex, so we can connect the new power station to the electricity transmission network.

  • This was included in EDF Energy's Development Consent Order, which was approved by the Secretary of State in March 2013.

Early 2021 to late 2025

 

Modify existing overhead lines in the Hinkley Point area

What we're doing:

  • Building temporary entrances and access roads to allow construction traffic to enter site from the local highway. You can find more information on our construction information page.

  • Modifying existing overhead lines in the Hinkley Point area, so they connect to the new Shurton substation at Hinkley Point C power station.

  • Building a short connection from Shurton substation to the existing substation at Hinkley Point B.

Mid 2022 to mid 2024

 

Upgrade Hinkley to Bridgwater overhead line

What we're doing:

  • Changing the wires on the existing pylons to upgrade the operating voltage of the line from 275,000 volts to 400,000 volts.
