Emily Farmer, project supervisor for National Grid, hosted a site tour of the New Cross site which is part of the London Power Tunnels 2 project.
This is a £1 billion project required to rewire south London via deep underground tunnels. This vital work will help keep Londoners connected to safe and reliable electricity supplies.
In total, 32.5km tunnels are being constructed deep below the road network between Wimbledon and Crayford, which will carry high voltage electricity cables.
Tunnel construction is well underway, with the project due to be complete and fully operational in 2027.
Students had the chance to see how the tunnel was designed and planned, as well as learning about the career progression of engineers.
Their natural curiosity saw them ask a series of questions and Emily was very impressed with their knowledge and interest.
