Proposed substation at Llandyfaelog will help meet growing electricity demand in South Wales
Facility is proposed in response to energy schemes requesting to connect to the grid in the region
National Grid is consulting communities for four weeks, between Tuesday 17 June and Tuesday 15 July
These are required to connect the new underground cables to the remaining existing overhead line and are located next to Rickpiece Plantation at the western end of the line, and in the fields adjacent to the Bridge Inn on Horton Road at the eastern end.
Balfour Beatty has received permission from Wiltshire Council to extend its working hours for the construction work on the CSECs to 8.00am to 9.00pm on Mondays to Fridays.
- As demand for electricity rises, Grimsby to Walpole will help connect more home-grown British energy, boosting local economies, creating jobs, and providing cleaner, more affordable energy.
- Part of National Grid’s The Great Grid Upgrade, the largest overhaul of the grid in a generation.
- Eight-week public consultation runs from 11 June to 6 August 2025
National Grid shares early-stage proposals for new electricity transmission infrastructure from Weston Marsh to East Leicestershire, needed to boost home-grown energy and meet growing electricity demand in the East Midlands.
- Collaboration with Hyperion Robotics and the University of Sheffield will trial low-carbon 3D-printed concrete foundations including at National Grid’s Deeside Centre for Innovation in North Wales
- Innovation could reduce waste, carbon emissions and costs to consumers of network construction
- If rolled out across National Grid substations the technology could save up to 705 tons of concrete and 323 tons of CO2 and deliver £1.7 million in consumer savings versus traditional methods over a 10-year period
To ensure the safety of our team while materials are being moved onto the site, traffic management measures will be in place from 09:30 to 15:00 on 9, 10 and 13 June 2025.
This work will be carried out by Balfour Beatty, on behalf of National Grid.
LineVision’s Dynamic Line Rating (DLR) technology has been installed on National Grid’s network to increase the capacity of over 275 kilometres of overhead line conductor.
The sensors and data analytics platform will highlight spare capacity on overhead power lines allowing for the integration of more renewable power.
At National Grid, we believe in the power of education and the importance of supporting initiatives that foster learning in Science, Technology, Engineering, and Mathematics (STEM).
