Walpole Substation expansion
National Grid Electricity Transmission (NGET) owns and maintains the electricity transmission network in England and Wales. We transport electricity from where it is generated, such as solar and offshore wind farms, to regional substations, where it then continues on its journey to homes and businesses.
To ensure that everyone can access electricity from renewable sources, we are working to build a cleaner, fairer, and more affordable energy system that serves everyone, and powers the future of our homes, transport and industry.
About Walpole Substation expansion
The Walpole Substation expansion is required to accommodate new infrastructure at the existing substation. The work will be essential to connect new sources of renewable energy, manage power flows on the network and support future demand. We will also be upgrading the existing technology, which was originally installed when the substation was built in the 1960s.
Our proposals for Walpole Substation are part of The Great Grid Upgrade - the largest overhaul of the grid in generations.
The Great Grid Upgrade will play a significant part in meeting the UK Government’s plans to power all homes and businesses with green energy by 2030 ensuring our electricity network is fit for the future.
What we are proposing
The Walpole Substation expansion involves the construction of new infrastructure in and around the existing substation footprint.
We have permitted development rights to deliver some of the work needed for this project, which is indicated by the blue boxes on the map.
Other parts of the project will require planning permission – indicated by the yellow boxes on the map. This new infrastructure will facilitate new connections to our network, including renewable energy sources, and will support future demand.
Biodiversity net gain
We are committed to providing a minimum of 10% biodiversity net gain in areas where we work – this means there will be an improvement on the existing biodiversity in the area once we have finished our project.
Surveys are underway to assess the expected level of vegetation removal including plans for additional landscaping and planting - this will form part of our planning application.
Working with other projects
Walpole Substation expansion is not part of EGL 3 and EGL 4 or Grimsby to Walpole. Please be assured we are working closely with our colleagues on these projects to minimise disruption to local communities.
Taking part in our public consultation
The Walpole Substation expansion project consultation has now closed. Thank you to all those that submitted feedback and attended our in-person event and public webinar.
The project team will review the feedback received ahead of submitting a planning application later this year. To keep you informed, we will publish project updates on this website in due course.
