National Grid Electricity Transmission (NGET) is proposing to build a new 400 kilovolt (kV) electricity substation approximately 1.4km to the east of Navenby.
We've submitted the planning application for the proposed substation to North Kesteven District Council (NKDC). Details of the planning application can be viewed on the NKDC website planning portal using the link below and reference 26/0575/FUL.
Copies of the key documents from our application will be available shortly in local community hubs. We will share the locations of the documents, as soon as possible.
Should the application be decided by the NKDC planning committee, we will let you know when this information is shared.
We’d like to thank all of you that submitted feedback on our proposals and attended our in-person or online consultation events in September 2024.
What we need to do
The way we generate electricity has changed and is continuing to change. This project is being developed alongside The Great Grid Upgrade, the largest overhaul of the electricity grid in generations. It comprises major infrastructure projects that will both scale up the grid and update our existing networks. It will enable us to carry more home-grown renewable energy from where it is generated to where it is needed, boosting Britain’s energy security. The Great Grid Upgrade will provide homes and businesses with secure, cleaner, home-grown British energy from more affordable sources.
We’re responsible for making sure electricity is transported safely and efficiently from where it is produced to where it is needed and as a regulated business, we have a legal obligation to connect customers to our network when a connection request is made.
Based on current demand around Navenby, it’s not possible to connect everything proposed in the area to existing regional substations such as Bicker Fen. To connect new developments to our network, we’ve identified that a new 400 kilovolt (kV) substation is needed.
Our proposals
The proposed 400 kV substation would be located to the north of Heath Lane and set back from the road, covering approximately 11 hectares.
This will be an ‘open air’ substation and a maximum height of 15 metres.
While four new pylons will need to be constructed as part of the plans, two existing pylons within the site will be dismantled.
The construction of a new access road off Heath Lane, as well as a road within the new substation, also form part of the plans.
Site selection
We've identified this site as the most suitable option through a formal substation siting study, where five possible sites were shortlisted.
From these five evaluated sites in the local area, a rigorous optioneering process was carried out, taking into consideration the impact on the local community, proximity to the existing overhead line to reduce the need for new pylons and overhead lines, environmental factors, land availability and much more.
Consultation
Our consultation for Navenby substation closed on 17 October 2024. Thank you to everyone who provided feedback and attended either our online or in-person event.
Copies of the banners and other materials issued throughout our consultation can be found in the document library.
Changes made to our proposals since consultation
Several changes have been made to our plans since we consulted with members of the local community in September 2024.
Landscaping plan
The landscaping approach has developed since our original consultation with the local community. Adjustments have been made to improve screening, reduce visual effects and better integrate the substation into its surroundings. Design plans now include landscape screening layouts along the south east of the application boundary. The aim of the landscaping is to screen views of the substation to the east and south.
The amenities building has been designed with a dark grey steel cladding, instead of a brick finish, which more closely reflects the character of agricultural buildings in the surrounding area. This would allow the structure to sit more discreetly within the rural landscape.
Enhancing the environment
Biodiversity Net Gain (BNG) is a way to ensure that the environment is left in a better state after construction than it was before the work started.
The decline of biodiversity in the UK is well documented, and we are conscious that our activities can impact habitats and therefore species’ ability to thrive. We have committed to
deliver BNG on site to the existing standard, plus 10%.
Once customer cabling routes are confirmed, the full BNG plan will be finalised, but currently we’re aiming to leave existing landscaping and screening where it is, removing the absolute minimal amount around the site boundary. We are also planning to keep existing trees that are on the edge nearest the village and have some open grassland to support skylarks.
More information about our plans can be found in our latest newsletter.
Community Benefit
Community Funds
In March 2025, the Government published new guidance for transmission owners that set out how communities hosting large infrastructure projects should be rewarded for doing so.
The introduction of this guidance means that, if our proposals for Navenby are approved, £530,000 will be available to invest in local community projects.
When the fund is available, we will consult with local organisations, charities and groups on how the money should be spent. If you represent a local charity or community group and would like to apply, further information is available on our website or contact our community relations team at [email protected].
