Following our Stage 1 consultation (2023) for North Humber to High Marnham, and before deciding which corridor to take forward to develop more detailed proposals, we would like to seek views about a potential alternative corridor between South Wheatley and High Marnham. This is referred to as the eastern corridor. The localised consultation is happening between 9 July and 6 August 2024.

Our proposals between South Wheatley and High Marnham

In June 2023, we introduced our proposals to build approximately 90 kilometres (km) of new 400,000 volt (400 kV) overhead electricity transmission line between two new substations – one to the north of Hull near Creyke Beck and one at High Marnham in Nottinghamshire.

Since the close of Stage 1 consultation in July 2023, we have reviewed all the consultation feedback received and undertaken a backcheck and review of the Corridor Preliminary Routeing and Siting Study (CPRSS) published in 2023. Feedback received and this further work has identified the eastern corridor as a potential alternative corridor between South Wheatley and High Marnham in Nottinghamshire.

The eastern corridor is routed in a south-easterly direction, passing to the south of Sturton le Steeple and avoiding West Burton Power Station. You can read more about the eastern corridor in our Addendum to Project Background Document and Supplementary Corridor and Routeing Report

You can also see the proposals for the eastern corridor below, or in the interactive map

Eastern Overhead Line Corridor for Consultation. View larger image.

We are now seeking your views and comments on the eastern corridor before deciding on a proposed overall preferred corridor and route, and before developing more detailed proposals, which will form part of our next stage of consultation in 2025.

High Marnham substation update

A consultation on the proposals for the new High Marnham substation took place in April and May 2024 ahead of the intended submission of planning application in early 2025. The new 400kV substation at High Marnham is currently being progressed as part of our Brinsworth to High Marnham project. You can find more information on the project website - www.nationalgrid.com/b-hm.

2024 Localised consultation document library

All the documents provided during our Stage 1 consultation are available in the Document Library. Additionally, we have published a number of materials as part of this consultation.

Upcoming consultation events and webinars

Please come along to our face-to-face public information events, which are being held at the following locations across the eastern corridor. You will have the opportunity to find out more about our proposals, view and take away some printed materials and speak to experts within the team.

Next steps

North Humber to High Marnham is classified as a Nationally Significant Infrastructure Project under the Planning Act 2008.  We will, therefore, submit an application for a Development Consent Order (DCO) to the Planning Inspectorate. After considering the DCO application, the Planning Inspectorate will make a recommendation to the Secretary of State for Energy Security and Net Zero, who, in turn, will then decide whether development consent should be granted for the project. 

We haven’t decided on the preferred corridor in this southern most section of the route and further assessment work has to be undertaken before we will be able to identify the overall preferred alignment of the project. Feedback from both the Stage 1 (non-statutory) consultation (2023) and localised (non-statutory) consultation (2024), together with further technical assessments including environmental surveys, will be considered when deciding on the overall preferred corridor. We will seek everyone’s views about more detailed proposals at our Stage 2 (statutory) consultation in 2025.
