London Power Tunnels represents a significant £1bn investment in London and follows the success of the original project, north of the Thames.
The arrival of this tunnel boring machine marks a significant milestone for the project and the start of Edith’s journey, to help construct 32.5km of tunnels deep below the streets of South London between Wimbledon and Crayford.
Minster for London, Paul Scully, formally inaugurated the machine ‘Edith’ which was named by staff on the project.
The name Edith was chosen to honour Edith Clarke, the first female electrical engineer and pioneer who used maths to improve our understanding of power transmission.
‘Edith’ was also blessed by a local religious leader next to an image of Saint Barbara, the patron saint of underground workers.
This is a tradition carried out on tunnelling projects, to watch over and protect its workers.
A milestone for this project
Alice Delahunty, president of electricity transmission at National Grid, said: “Our London Power Tunnels project is making sure electricity reaches homes and businesses in London safely, reliably and efficiently.
“The arrival and launch of the TBM at New Cross is an exciting milestone for this project, so I am delighted that we are able to host an event to mark this occasion.
“A huge amount of work has gone into making this possible, so I would like to thank everyone who has been involved in the success of this project so far, especially as the project began at the start of the pandemic.
“Despite its challenges our engineers have been able to deliver this vital project and reach this milestone.”
Minister for London, Paul Scully, added: “As well as keeping the lights on, the £1 billion investment through the London Power Tunnels project shows the full range of London’s engineering talent that is helping to build back better from the pandemic.
“It was great to smash the metaphorical champagne bottle across National Grid’s new 140-tonne tunnel boring machine, which is heavyweight tech for a heavyweight project, and I wish it every success on its maiden voyage.”
