Survey update
In autumn 2025, we will be carrying out archaeological surveys. These surveys will include excavating trenches for investigation and will be carried out by specialist contractors. By investigating the route at this early stage, we will ensure that any archaeological remains are found and recorded. Any archaeological remains found will tell us about the people who lived in the parts of East Yorkshire, North Lincolnshire and Nottinghamshire crossed by the scheme from the Stone Ages, Bronze and Iron Ages, Romans, Anglo-Saxons, medieval and post-medieval periods, when many of today’s farms were established.
While some surveys will take place on public rights of way, there will be instances where we need to access private land in order to carry out our work. We will always seek to agree this with the landowner/occupier before the work takes place, and the members of our team carrying out survey works will always carry identification. Where access can't be voluntarily agreed with landowners through licences, National Grid can use statutory powers to gain entry onto land, however, ongoing engagement with the landowner and occupiers will be maintained throughout this process. Recently, we sent out a number of S172 notices to land parcels along the route to ensure that access could be gained for these surveys.
If you are a landowner or occupier and have questions about surveys, you can speak to our Lands team at Dalcour Maclaren. They can be contacted by email at [email protected], by phone on 0333 188 3511, or by writing to The Barn, Bignell Park Barns, Chesterton, Bicester, OX26 1TD.
About North Humber to High Marnham
National Grid Electricity Transmission is proposing to reinforce the electricity transmission network between the north of England and the Midlands by building a new 400 kilovolt (kV) electricity transmission connection between two proposed substations at Birkhill Wood and High Marnham.
The proposed reinforcement is required to increase the capability of the electricity transmission network between the north of England and the Midlands. It is also needed to facilitate the connection of proposed new offshore wind farms that are planned in the area.
You can read more about our proposals here, or view them on our Interactive map.
Why is this happening?
With growing offshore wind generation and increased interconnection, an anticipated tripling of wind generation connected across the Scottish networks by 2030, and the Government’s ambition to connect 50 GW of offshore wind by 2030, north-south power flows are set to increase. If all the proposed new offshore wind that is planned to connect into the Creyke Beck area gets built, this would amount to just over 13 gigawatts (GW) of generation capacity by the early 2030s.
The existing network serving the Creyke Beck area can export just under 7 GW of electricity while remaining compliant with the Security and quality of supply standards to which the network is operated. The network as it is today would therefore not have the capacity needed to export the significant forecast increase in contracted generation out of the area, or to accommodate the north-south power flows that are expected. Because of this, we need to increase the capability of the transmission network between the north of England and the Midlands.
