Our proposals
We propose a series of works to build and operate three new substations – one in Rotherham, another near Chesterfield and a third in High Marnham – to allow us to safely carry more energy between the North of England and the Midlands.
The proposed substations would also enable us to upgrade the existing Brinsworth to Chesterfield and Chesterfield to High Marnham overhead electricity lines and connect future electricity transmission network projects as part of The Great Grid Upgrade.
Rotherham
We propose to build and operate a new 400 kV substation to the east of Long Lane Rotherham, South Yorkshire.
We need to build a new substation as there isn’t sufficient space to accommodate the additional equipment at the existing Brinsworth substation, off West Bawtry Road.
We expect it will be an air insulated switchgear (AIS) 400 kV substation as the proposed site has sufficient space to accommodate an AIS – which has a greater footprint than a gas insulated switchgear (GIS) substation.
The new substation would be within a compound approximately 380 metres x 200 metres - the size of around 11 football pitches – and include approximately 12 bays, network stability equipment, standard substation plant and control infrastructure.
The highest structures within the substation compound would be six overhead line gantries, which are bridge-like structures with platforms used to support equipment and cabling. At approximately 12 metres, they would be the highest structures within the substation compound. The site's footprint has the potential for some future expansion if required.
We also propose temporary diversions of the existing Brinsworth to Thorpe Marsh and Brinsworth to Chesterfield overhead lines, with temporary pylons during construction. We expect these temporary diversions to be in place for less than six months. We’ll include details when we submit our planning application.
To turn the overhead line into the new substation, we’d need to build nine new pylons and remove nine old pylons—four to the south and five to the north.
