Overview – Winter 2023
Located in the centre of the new Hinkley connection route, the new Sandford substation is complete and ready for energisation.
In the same area, we’ve constructed nine new lattice pylons and installed 700 metres of underground cable toconnect the existing 132,000 volt power line from Weston-super-Mare to the new substation in the spring.
In the north of the Hinkley Connection route, work to erect 68 new T-pylons between Sandford and Portbury, is well underway. The T-pylons will join a line of 27 lattice pylons through Avonmouth to make the final connection Seabank substation.
Thank you from everyone working on the project for your patience and understanding as we progress with this vital 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.
Sandford timeline
April 2020 to late 2023
Build Sandford substation
What we're doing:
Advance planting and landscaping.
Installing a temporary construction compound adjacent to the site of the new substation.
Building a new substation, just north of the A368, in order to maintain local electricity supplies in the area.
Early 2021 to mid 2023
Modifications to the existing 132,000 volt overhead line to Weston-super-Mare
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.
Installing a temporary construction compound north of Sandford substation.
Building a new connection from Sandford substation to the existing overhead line that goes to Weston-super-Mare. It will be made up of 700m of underground cable and nine new lattice pylons. This is to ensure local electricity supplies are maintained.
Removing 1.5 km of the existing overhead line to Weston-super-Mare that runs north-west from Sandford near Puxton.
Early 2021 to mid 2025
Build a new 400,000 volt overhead line
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.
Building a new overhead line from Sandford substation to Seabank substation (approximately 31.2 km).
We will use T-pylons in this area.
Early 2021 to mid 2025
Remove existing 132,000 volt overhead line
What we're doing:
Removing existing overhead line from the A368 in Sandford to Avonmouth.
Late 2021 to late 2023
Modifications to the existing 132,000 volt overhead line to Churchill
What we're doing:
Building a new overhead line using wooden poles (285m) from Sandford substation to the existing overhead line that goes to Churchill, to ensure local electricity supplies are maintained.
Removing approximately 550m of the existing overhead (lattice pylons) to the south Sandford substation.
