Harker Energy Enablement
REDAS is providing tendering support to VEJV on Harker Energy Enablement Project.
National Grid
Our substation at Harker, near Carlisle in Cumbria
has been in service since the 1960s. As the
equipment on site gets older, technology advances
and demand on the electricity network increases, we
will need to replace infrastructure at Harker Substation
and increase its capacity.
We are planning to extend the substation to the north of the existing site in order to replace and rebuild the existing equipment.
The project consists of three main elements:
Replace and rebuild the existing substation by extending onto an adjacent field.
Reconfigure the short sections of the overhead lines into the extended Substation.
And new conductors (the wires between the pylons) onto 8km of existing pylons between
the Harker substation and the Scottish Border.
Our plans allow us to provide the improvements required to maintain the existing electricity transmission system.
They will also ensure the substation is prepared for future demand so it can continue to serve as a critical point of
intersection on the UK energy network, connecting supplies between Scotland to England. This work is part of National
Grid’s contribution to the Government’s target to achieve net zero carbon emissions by 2050.
To meet these targets, more generation from renewable energy sources such as wind needs to be connected to the
electricity network. Our proposed work will provide additional network capacity to accommodate this generation.
