To help ensure the continued safe operation of existing sites and equipment and to facilitate future infrastructure investment, National Grid wishes to be involved in the preparation, alteration and review of plans and strategies which may affect their assets
Guidance on development near National Grid assets
National Grid is able to provide advice and guidance to the Council concerning their networks and encourages high quality and well-planned development in the vicinity of its assets.
Electricity assets
Developers of sites crossed or in close proximity to National Grid assets should be aware that it is National Grid policy to retain existing overhead lines in-situ, though it recognises that there may be exceptional circumstances that would justify the request where, for example, the proposal is of regional or national importance.
National Grid’s ‘Guidelines for Development near pylons and high voltage overhead power lines’ promote the successful development of sites crossed by existing overhead lines and the creation of well-designed places. The guidelines demonstrate that a creative design approach can minimise the impact of overhead lines whilst promoting a quality environment. The guidelines can be downloaded here: https://www.nationalgridet.com/document/130626/download
The statutory safety clearances between overhead lines, the ground, and built structures must not be infringed. Where changes are proposed to ground levels beneath an existing line then it is important that changes in ground levels do not result in safety clearances being infringed. National Grid can, on request, provide to developers detailed line profile drawings that detail the height of conductors, above ordnance datum, at a specific site.
National Grid’s statutory safety clearances are detailed in their ‘Guidelines when working near National Grid Electricity Transmission assets’, which can be downloaded here:www.nationalgridet.com/network-and-assets/working-near-our-assets
Gas assets
High-Pressure Gas Pipelines form an essential part of the national gas transmission system and National Grid’s approach is always to seek to leave their existing transmission pipelines in situ. Contact should be made with the Health and Safety Executive (HSE) in respect of sites affected by High-Pressure Gas Pipelines.
National Grid have land rights for each asset which prevents the erection of permanent/ temporary buildings, or structures, changes to existing ground levels, storage of materials etc. Additionally, written permission will be required before any works commence within the National Grid’s 12.2m building proximity distance, and a deed of consent is required for any crossing of the easement.
