Brentwood Borough Council: Addendum of Focussed Changes to the Pre Submission Local Plan
SUBMISSION ON BEHALF OF NATIONAL GRID
National Grid has appointed Wood to review and respond to development plan consultations on its behalf. We are instructed by our client to submit the following representation with regard to the current consultation on the above document.
About National Grid
National Grid Electricity Transmission plc (NGET) owns and maintains the electricity transmission system in England and Wales and National Grid Electricity System Operator (NGESO) operates the electricity transmission network across the UK. The energy is then distributed to the eight electricity distribution network operators across England, Wales and Scotland.
National Grid Gas plc (NGG) owns and operates the high-pressure gas transmission system across the UK. In the UK, gas leaves the transmission system and enters the UK's four gas distribution networks where pressure is reduced for public use.
National Grid previously owned part of the gas distribution system known as 'National Grid Gas Distribution limited (NGGDL). Since May 2018, NGGDL is now a separate entity called 'Cadent Gas'.
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 National Grid's assets.
Proposed sites crossed or in close proximity to National Grid infrastructure:
Following a review of the above development plan, the following sites have been identified as being crossed
or in close proximity to National Grid infrastructure. Further details are provided in the table overleaf.

Electricity Transmission
Site Ref Asset Details Appendix Ref E11- Brentwood Enterprise Park
ZB Route - 275Kv two circuit route from Warley substation in Havering to Waltham Cross substation in Epping Forest
ET329 (GT113) Gas Transmission Site Ref Asset Details Appendix Ref R01

Strategic Allocation Brentwood Hills Garden Village
FM05 - Braintree to Horndon GT111

R06 - Land off Nags Head Lane, Brentwood
FM18 - Stapleford Tawney to Tilbury Thames North GT112

E11- Brentwood Enterprise Park
FM18 - Stapleford Tawney to Tilbury Thames North GT113 (ET329)

Please see attached plan referenced ET329, GT111, GT112 & GT113 at Appendix 2. The proposed sites are crossed by a National Grid high voltage electricity transmission overhead line and/or National Grid underground high-pressure gas pipeline. 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 inground 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. You can find National Grid's guidelines for developing near Over Head Lines here:

Electricity Distribution
UK Power Networks owns and operates the local electricity distribution network in Brentwood Borough Council. Contact details can be found at www.energynetworks.org.uk.

National Grid Asset Guidance
National Grid seeks to encourage high quality and well-planned development in the vicinity of its high voltage overhead lines. Land beneath and adjacent to the overhead line route should be used to make a positive contribution to the development of the site and can for example be used for nature conservation, open space, landscaping areas or used as a parking court. National Grid, in association with David Lock Associates has produced 'A Sense of Place' guidelines, which provide detail on how to develop near overhead lines and offers practical solutions which can assist in avoiding the unnecessary sterilisation of land in the vicinity of high voltage overhead lines.
Potential developers of these sites should be aware that it is National Grid policy to retain our existing overhead lines in-situ. The relocation of existing high voltage overhead lines will only be considered for projects of national importance which has been identified as such by central government. National Grid requests that any High-Pressure Gas Pipelines are taken into account when site options are developed in more detail. These pipelines form an essential part of the national gas transmission system and National Grid's approach is always to seek to leave our existing transmission pipelines in situ. Please refer to the Health and Safety Executive (HSE) in the first instance.
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 easement strip, and a deed of consent is required for any crossing of the easement. In the first instance please consider checking with the Land Registry for the development area.
If you require any further information in relation to the above and/or if you would like to check if National Grid's transmission networks may be affected by your works, please contact National Grid's Plant Protection team viaplantprotection@nationalgrid.com or visit the website: https://www.linesearchbeforeudig.co.uk/
