National Grid Breaks Ground on Bengeworth Road Electricity Substation in London

The National Grid and Linxon teams have started construction of a new 400-kV electricity substation on Bengeworth Road in Lambeth in London, UK.

The substation is a crucial aspect of the London Power Tunnels project, a seven-year, £1 billion ($1.25 billion US) endeavor by National Grid to rewire South London via underground tunnels to replace outdated high-voltage cables, increase capacity, and ensure a dependable supply of electricity to London residents.

The substation will be built on the existing site boundary of UK Power Network’s Bengeworth Road substation, connecting the LPT route from Wimbledon to Crayford. It will have an essential role in supplying electricity to households and businesses across London, maintaining voltage limits on the transmission network and supporting the transport of clean and green energy.

Hitachi Energy’s SF6 free gas-insulated switchgear technology will be used to construct the substation.

National Grid plans to phase out SF6 from electrical assets by 2050.
