Consultation on Grimsby to Walpole transmission infrastructure

12 March 2024

Electricity pylon

National Grid has announced the commencement of the first non-statutory consultation for the Grimsby to Walpole transmission infrastructure project in Lincolnshire. 

The proposed project aims to construct approximately 140 kilometres of transmission infrastructure as part of The Great Grid Upgrade, as well as five new substations.

National Grid has stated this is needed for a variety of reasons, including:

  • A projected increase in North-South power flows, anticipating a need to transfer 25.9GW of electricity between the North and Midlands by 2033.
  • New sources of electricity connecting to the region, including up to 18.6GW of new generation projects by the mid 2030s, and 5.8GW of subsea links.

The NFU has submitted a comprehensive response to this consultation on behalf of all members affected. In this response, any issues that impact our members that require attention from National Grid were raised.
