In May 2024, we completed the refurbishment of the existing 400,000 volt overhead line between Bramford substation in Suffolk and Norwich substation in Norfolk.

Network Planning

As part of our investment in the energy network in East Anglia, we replaced all the fittings and wires on the existing pylons along the 62 kilometre route and made some changes to the network at Yaxley to replace a pylon and connect the overhead line into the new substation.

Completing this work strengthens the transmission network in East Anglia, enabling us to carry more power down the lines to homes and businesses where it is needed.

At National Grid, we’re always working to maintain and improve our network to ensure we operate a safe and reliable electricity system now and in the future. As part of these commitments, we repaint pylons approximately every seven years. 

Our contractor, Actavo, is currently repainting the pylons along the Bramford to Norwich overhead line route. This work is expected to be complete during 2025. With the overhead line mainly routed across fields, the repainting of the individual pylons along the route is not expected to cause any local disruption. 

Thank you to communities

We’d like to thank communities and landowners along the route for their co-operation and patience during the two-year refurbishment programme. Their support has enabled us to maintain the health of our network, ensuring we continue to deliver cleaner, greener electricity efficiently, reliably, and safely, supporting the UK Government’s goal of achieving net zero emissions by 2050.
