Notice is hereby given that National Grid Electricity Transmission plc (“National Grid”) of National Grid House, Warwick Technology Park, Gallows Hill, Warwick, CV34 6DA intends to apply to the Secretary of State for a Development Consent Order (“DCO”) under Section 37 of the Planning Act 2008 (as amended) to authorise the construction of Norwich to Tilbury.

Norwich to Tilbury (the “Project”) is a proposal by National Grid to upgrade the electricity transmission system in East Anglia between Norwich and Tilbury. The Project includes a new 400 kilovolt (“kV”) electricity transmission connection of approximately 184 kilometres ("km”) in overall length from Norwich Main Substation and Tilbury Substation via Bramford Substation.

National Grid will consult on all aspects of the proposed development for the Project, including:

• approximately 159 km of new overhead line supported on approximately 510 steel lattice pylons (approximately 50 metres (“m”) in height) some of which are gantries (typically up to 15 m in height) within proposed Cable Sealing End (“CSE”) compounds, or existing or proposed substations

• approximately 25 km of 400 kV underground cabling some of which is located through the Dedham Vale National Landscape (formerly known as Dedham Vale AONB)

• six new CSE compounds, each with a permanent access, to connect the overhead lines to the underground cables

• a new 400 kV East Anglia Connection Node (“EACN”) substation, with a new permanent access, on the Tendring Peninsula. This is proposed to be an Air Insulated Switchgear (“AIS”) substation

• substation extension works at the existing Norwich Main, and Bramford substations and works within the existing Tilbury Substation to connect and support operation of the new transmission connection• temporary works associated with the construction of the Project.

An alternative design at the Waveney Valley (referred to as the Waveney Valley Alternative) is also being considered and is the subject of consultation and ongoing assessment. This design alternative, if taken forward, would result in changes to those elements of the Project set out below. This would instead comprise:

• installation of approximately 157 km of new 400 kV overhead line

• installation of approximately 27 km of 400 kV underground cabling (some of which is located through the Dedham Vale National Landscape)

• eight new CSE compounds (each with a permanent access) to connect the overhead lines to the underground cables.

All works listed above would be consistent with either alternative.

In other words, the Waveney Valley Alternative, if taken forward and based on the 2024 preferred draft alignment would comprise approximately 2 km less new 400 kV overhead line and approximately an additional 2 km of 400kV underground cabling and two additional new CSE compounds, each with a permanent access, to connect the overhead lines to the underground cables.

Third party utilities diversions and / or modifications would also be required to facilitate the construction of the Project. There would also be land required for mitigation, compensation and enhancement of the environment including Biodiversity Net Gain.

As well as the permanent infrastructure, land would also be required temporarily for construction activities including for example working areas for construction equipment and machinery, site offices, welfare, storage and temporary construction access.

The Project would be designed, constructed and operated in accordance with applicable health and safety legislation. The Project would also need to comply with design safety standards including the National Electricity Transmission System (“NETS") Security and Quality of Supply Standard, which sets out the criteria and methodology for planning and operating the NETS. This informs a suite of National Grid policies and processes, which contain details on design standards required to be met when designing, constructing and operating assets such as proposed for the Project.

The proposed application will seek authorisation for the compulsory acquisition of land and interests in and rights over land, overriding easements and other rights, the temporary use of land, and other ancillary powers.

The Project is an Environmental Impact Assessment (“EIA”) development, as defined by the Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (as amended). An Environmental Statement will therefore be submitted as part of the proposed application, which will contain information about the environmental effects of the Project.

All documents, plans and maps showing the nature and location of the proposed development, including the preliminary environmental information, will be available to download free of charge from 12:00 noon on 10 April 2024 until 11:59pm 18 June 2024 on http://www.nationalgrid.com/n-t (via the document library page).

Reference copies of certain documents showing the nature and location of the proposed development will also be available to view free of charge from 12:00 noon on 10 April 2024 at the following inspection points in the vicinity of the Project for the duration of the consultation (until 18 June 2024):
