The UK Government has committed to reaching net zero emissions by 2050. This means achieving a balance between the greenhouse gases put into the atmosphere and those taken out. Decarbonising the energy system is vital to achieving net zero.


At National Grid Electricity Transmission (NGET), we are investing around £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 net zero ambitions into reality.

With the announcement of a general election on 4 July, we are re-scheduling consultation events that were planned during the pre-election period and we are extending the deadline for consultation feedback to 11:59pm Monday 15 July 2024.

For more details on the rescheduled dates, please visit here.

The consultation will remain open during the election period and your ability to provide feedback will not be affected. Our phoneline and contact email will also continue to be monitored throughout this period should you require any assistance or have any questions.

Project update

We are now consulting on our early proposals for the onshore elements of EGL 3 and EGL 4 in England. The deadline for providing feedback is 11:59pm Monday 15 July 2024. 

Introducing EGL 3 and EGL 4

National Grid Electricity Transmission (NGET) is planning to enhance the electricity network with proposals for EGL 3 and EGL 4 – two new primarily offshore high voltage electricity links and associated onshore infrastructure between Scotland and England.

The links would transport enough clean energy from Scotland to power up to four million homes in the Midlands and South of England, playing an important role in building a more secure and resilient future energy system and the decarbonisation of the UK electricity system. 

In England, the proposed onshore elements of EGL 3 and EGL 4 would be in the districts of East Lindsey, Boston and South Holland, in Lincolnshire; and the district of King’s Lynn and West Norfolk, in Norfolk.

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

EGL3 and EGL4

Read more about what we’re proposing to build and install here.

Both EGL3 and EGL 4 are in their early stages of development, and we will be seeking consent for the English onshore elements of both via one application to the Planning Inspectorate for a Development Consent Order (DCO). Although EGL 3 and EGL 4 are independent of one another, in effect separate projects, due to their ultimate common connection point in England (the proposed new Walpole substation), we decided to develop them in parallel. In addition to enabling one DCO application, this coordinated and co-located approach to their routeing and siting provides the opportunity to potentially reduce the extent of community and environmental impact and disturbance.

Consultation is an important part of the DCO process as it enables everyone to comment on our proposals, with feedback helping to inform the development of our proposals – along with technical assessments and environmental surveys – before we submit our DCO application to the Planning Inspectorate. 

The Planning Inspectorate will review and examine our application, and encourage submission of views from statutory stakeholders, communities and other interested parties, before making 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 see the Planning Inspectorate website.

Taking part in our Stage 1 (non-statutory) public consultation

This Stage 1 consultation – running from Tuesday 23 April to Monday 15 July 2024 – is designed to introduce our proposals and gain your early feedback. This stage is called a ‘non-statutory’ consultation, which comes before the Stage 2 statutory consultation that we will carry out later in the process before we finalise our proposals and prepare our application for development consent. This consultation process relates only to the English onshore elements of EGL 3 and EGL 4. The deadline to provide feedback is 11:59pm on Monday 15 July 2024.
