Norwich to Tilbury consultation

Statement on Targeted Consultation 2025

National Grid is currently undertaking targeted consultations on sections of the proposed Norwich to Tilbury project in Essex. They are considering some localised changes to the alignment and design of the proposed overhead powerline as it passes through the county. Most of these changes have been identified following the feedback from last summer’s statutory consultation along with the consideration of the findings from environmental and engineering surveys. 

The consultation runs from 12 noon Tuesday 25 February to 11:59 pm on Thursday 27 March 2025. 

Visit the National Grid website to find out more about the proposed changes and how to comment.

Biodiversity Net Gain (BNG) for NSIPs 

Essex County Council has commissioned two reports to evaluate the feasibility of requiring developers to achieve a 20% BNG. This is an increase from a proposed minimum 10% figure. These reports, funded by government grants, will be shared with developers, planners, and scheme promoters to serve as an evidence base for advocating enhanced BNG. NSIP Promoters will be expected to include in proposals at the earliest opportunity how they will meet this 20% requirements.
