The way the UK generates electricity is changing rapidly, and we are transitioning to cleaner and more secure forms of energy. This means we need to make changes to the network of overhead lines, pylons, cables and other infrastructure that transports electricity around the country, so that everyone has access to clean electricity from these new renewable sources.


At National Grid Electricity Transmission (NGET), 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 are 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. 

Project update

With the announcement of a general election on 4 July, we are rescheduling our consultation events that were planned during the pre-election period. We will be extending the deadline for consultation feedback. 

The consultation events that were planned between 30 May and 2 July – in person events and webinars - will now not take place on those dates. We will update you with revised dates as soon as rescheduled dates are confirmed.

Introducing Chesterfield to Willington

National Grid Electricity Transmission is proposing to enhance the electricity network by building and operating a new 60 kilometre (km), 400 kilovolt (kV) overhead electricity line.  This overhead line would connect at a new 400 kV substation at Chesterfield in Derbyshire and the existing Willington substation in South Derbyshire. The new substation at Chesterfield will be consented and delivered by a separate essential project - Brinsworth to High Marnham. Other local network configurations would also need to be carried out as part of this project. 

Our Chesterfield to Willington proposals will support the country’s energy transition and make sure the grid is ready to connect to more and more sources of low carbon electricity generated in Britain. The project would transport clean energy from the North of England to homes and businesses in the Midlands and play an important role in building a more secure and resilient future energy system. 

Without this upgrade, the network won't have the capacity that is needed to move electricity from where it is produced to where it is needed. Therefore, we need to upgrade it to maintain system compliance and prevent overloading circuits as they transport the energy that is generated. 

The Brinsworth to High Marnham project includes a proposal to build and operate a new 400 kV substation in Chesterfield. This new substation would be the northern connection point for Chesterfield to Willington. The substation does not form part of this project however, it will be considered during the ongoing design studies and when assessing cumulative effects.

These proposals form part of The Great Grid Upgrade, which is the largest overhaul of the grid in generations.

Read more about what we’re proposing here.

Certain types of energy infrastructure fall within the categories of Nationally Significant Infrastructure Projects (NSIPs), which require a Development Consent Order (DCO) under the Planning Act 2008.

To build and operate the new Chesterfield to Willington line, we require a DCO under this Act. Consultation is an important part of the DCO process and the feedback we receive will shape our plans ahead of submitting the DCO application, which we anticipate will be in 2026. 

Consultation on Chesterfield to Willington is planned to take place over two stages. The first, Stage 1 (also called a non-statutory consultation) is consultation on our early proposals to help shape our plans. The second, and often final stage, Stage 2 (our statutory consultation) is consultation on our more detailed proposals following the feedback provided in the first phase. 

All the feedback received throughout our consultation process will be recorded and reported in our final Consultation Report, including how we have had regard for your comments. The Report will form part of our application for development consent.

The Planning Inspectorate (PINS) will then review and examine our application. This includes encouraging further submission of views from communities and other interested parties, before it makes a recommendation to the Secretary of State for Energy Security and Net Zero, who will decide whether to grant consent. To find out more about the DCO process, please visit the Planning Inspectorate website.

Taking part in our Stage 1 consultation 

This Stage 1 consultation runs for eight weeks from 14 May 2024 and 9 July 2024. We are seeking views and local knowledge about the proposed area within which the proposed new line could be located. Our consultation is open to anyone who may have an interest in our proposals. Your feedback will help to inform more detailed proposals. 

The deadline for providing feedback is 11.59pm on Tuesday 9 July 2024.

Learn about the different ways you can take part in our consultation by visiting our Events and webinars page.

You can provide feedback by filling out our online feedback form.
