The way we generate electricity in the UK is changing rapidly, and we are transitioning to cheaper, cleaner and more secure forms of energy like new offshore windfarms. We need to make changes to the network of overhead lines, pylons, cables and other infrastructure that transports electricity around the country, so that everyone has access to the clean electricity from these new renewable sources.
We are proposing to build a new high voltage electricity transmission line and associated works between a new substation north of Hull at Creyke Beck in the East Riding of Yorkshire and a new substation at High Marnham in Nottinghamshire. Our proposals are part of The Great Grid Upgrade – the largest overhaul of the grid in generations.
The proposed upgrade is required to increase the capability of the electricity transmission network between the north of England and the Midlands. It is needed to facilitate the connection of proposed new offshore wind that is planned in the area.
Our first public consultation for the project has now closed. The project team are now reviewing the feedback received during this consultation. We will be taking that into account as we continue to develop more detailed proposals ahead of our next consultation in Autumn 2024. More information on how your feedback has helped shape our more detailed proposals will be made available then.
We have produced an interactive map, detailing our proposals for North Humber to High Marnham. This provides a more detailed map of our proposals in the area most relevant to you. You can type your postcode into the search box on the map to be taken straight to your property.
The need for network reinforcement
The UK Government has set out a commitment to achieve net zero emissions by 2050. This means achieving a balance between the greenhouse gases put into the atmosphere and those taken out. The energy industry plays a key part in this transition, from developing renewable energy generation, to upgrading the existing electricity transmission network to allow communities across the country to benefit from this clean energy. We are presenting some plans in your local area to help that transition and make sure the grid is ready.
Whilst it is vital that more of the energy we use comes from low carbon and renewable sources, both NGET and the Government recognise it is also important to keep the impact as low as possible on bills, people, communities and our natural environment. NGET is committed to finding the right balance between these factors to ensure our projects have a sustainable, positive impact.
The UK already has 13.6 gigawatts (GW) of offshore wind energy in operation. The Government’s recent British Energy Security Strategy outlines the ambition to increase energy from offshore wind to 50 GW by 2030 – more than enough to power every home in the UK. In Powering up Britain, the Government explains that the grid needs to be expanded at an unprecedented scale and pace to deliver more clean power and increase our energy security.
The North Humber to High Marnham proposal will support the UK’s net zero target by reinforcing the electricity transmission network between the north of England and the Midlands and facilitate the connection of planned offshore wind generation and interconnectors with other countries, allowing clean green energy to be carried on the network.
The reinforcement is needed because our existing power lines do not have sufficient capacity for all the new sources of electricity that we expect to connect to the network over the next ten years and beyond. Building North Humber to High Marnham, together with other proposals, will help meet this future energy requirement.
North Humber to High Marnham is a Nationally Significant Infrastructure Project which means an application for a Development Consent Order will need to be prepared and submitted to the Planning Inspectorate. Ultimately the Secretary of State will be responsible for making the final decision on the application.
The Great Grid Upgrade
The Great Grid Upgrade is the largest overhaul of the electricity grid in generations. Our infrastructure projects across England and Wales are helping to connect more renewable energy to your homes and businesses.
