The Great Grid Upgrade

The Great Grid Upgrade - Chesterfield to Willington

The UK Government has set out a commitment to achieve Net Zero emissions by 2050. The way we generate electricity in the UK is changing rapidly and we're transitioning to cleaner and more secure forms of energy from renewable sources, like new offshore wind farms.

At National Grid Electricity Transmission, we are investing £1.3bn each year to adapt and develop our network - of pylons, overhead lines, cables and substations - to connect new sources of low carbon energy to homes and businesses. We're investing for the future, connecting more and more low carbon electricity to our network and playing a crucial role in turning the UK's ambitions into reality.

From Tuesday 14 May until 11:59pm Tuesday 9 July 2024 we are consulting on our early proposals for Chesterfield to Willington. To enhance the electricity network by building and operating approximately 60 kilometres (km) of new 400 kilovolt (kV) overhead electricity line.

This overhead line would connect at a new 400 kV substation at Chesterfield (which will extend to the south of its existing 275 kV substation) and the existing Willington substation. It is proposed that the Chesterfield substation will be completed under a separate essential project, 'Brinsworth to High Marnham'. Other local network configurations would also need to be carried out as part of this project.

These proposals are part of The Great Grid Upgrade – the largest overhaul of the electricity transmission network in generations.
