UK, London: National Grid and Linxon have announced the start of construction of a new HV substation at Bengeworth Road, within the $1.24 B (£1 B) London Power Tunnels Project.
The new 400 kV substation is being built at the heart of London as part of National Grid’s seven-year project to rewire South London via deep underground tunnels. This way, the ageing HV cables will be replaced in an effort to expand the capacity and keep the citizens connected to a reliable electricity supply.
The high-voltage substation will be built using Hitachi Energy’s SF6 free gas-insulated switchgear technology, the first in the UK, and forms part of National Grid’s ambition to have no SF6 in electrical assets by 2050.
“Breaking ground at Bengeworth Road marks the first major milestone in the development of this new substation, which forms part of our £1 B project to completely rewire South London. We’ve been working closely with the local community to keep them informed as the project progresses, and we’re delighted that our Community Grant Fund has already benefited the Ruskin Park community. In addition, National Grid’s commitment to a biodiversity net gain of 10 % or more has also resulted in 27 new trees being planted in Ruskin Park, close to the new substation,” said Onur Aydemir, Project Director for London Power Tunnels.
If everything goes as planned, Bengeworth Road Substation will be completed in 2026.
