The Great Grid Upgrade in East Anglia
The Great Grid Upgrade will play a big part in the UK government’s plan to boost homegrown power. It will help the UK switch to clean energy and make sure our electricity network is fit for the future; carrying more clean, secure energy from where it’s generated to where you need it.
Along with Norwich to Tilbury, National Grid is developing a number of other projects in the region.
Sea Link, an offshore link between Suffolk and Kent. We will be consulting on the latest proposals in East Suffolk and Kent later this year.
Bramford to Twinstead
We also propose to build network reinforcement between Bramford substation in Suffolk and Twinstead Tee in Essex. Our application for a Development Consent Order was accepted for examination by the Planning Inspectorate in May (2023).
Refurbishing the existing overhead line
We are carrying out essential work to refurbish the existing 400 kV overhead line that runs between our substations at Bramford and Norwich. This includes replacing all the fittings and wires between the existing pylons. We started in late May and expect works to be complete by the end of this year.
Norwich Main substation extension
We need to extend our existing Norwich Main substation to connect two new wind farms (Equinor’s Sheringham Shoal and Dudgeon extensions and Orsted’s Hornsea 3) over the next few years. We will publish more information when plans have been developed further.
