Welcome - Our Chesterfield to Willington project
National Grid Electricity Transmission (NGET) is proposing to upgrade the electricity transmission network through the construction of a new high-voltage electricity transmission line with associated works in Derbyshire. The new 400 kV overhead line, approximately 60 kilometres (km) in length, will connect a new substation at Chesterfield area to the existing Willington Substation.
The existing network in the East Midlands region does not currently have the capacity to deliver future electricity demand to where it will be needed.
Chesterfield to Willington would play an important role in transporting more secure, cleaner, home - grown energy from more affordable sources – generated off the coast of Britain – to around two million homes in the Midlands and beyond.
Feedback
We are seeking comments on our proposals which have been updated since our Stage 1 consultation in 2024. The feedback received at that time, as well as further technical and environmental assessments, has helped to shape our proposals.
Our proposals for Chesterfield to Willington include:
A new 400 kV overhead line, approximately 60 kilometres (km) in length between a new substation in the Chesterfield area and the existing Willington Substation;
A new 400 kV substation at Chesterfield, to be built in the vicinity of the existing 275 kV Chesterfield Substation and the existing 132 kV National Grid Electricity Distribution (NGED) substation to the south east of Chesterfield (referred to as the ‘new Chesterfield Substation’);
Replacement of short sections of existing overhead line and local changes to the lower voltage distribution network to facilitate the construction of the Project; and
Other works needed for construction, such as temporary access roads, highway improvements, construction work compounds, ancillary works, utility diversions and drainage. Land would also be required for environmental mitigation and enhancement, which would deliver an overall Biodiversity Net Gain (BNG), an approach to development that leaves habitats in a better state than before.
