February 2016 was a momentous month for the London Power Tunnels Project with the successful operational handover of the first phase of the project. This milestone encompasses energisation of the cable between existing substations at Willesden and St John’s Wood via Kensal Green substation, the first new National Grid substation in London for over 20 years, and completes 7.4km of the tunnel network.
Commissioning will continue in phases with the tunnels becoming fully operational and delivering power across the capital by 2018.
In total over 200km of cable is being installed in our new 32km tunnel network, which stretches from Willesden in west London to Hackney in the east, and south from Kensal Green to Wimbledon. The tunnel construction was completed in March 2015.
Gareth Burden, Senior Project Manager, said: “London Power Tunnels has taken a quantum leap forward with our engineers successfully commissioning the first section of tunnel. This milestone is a major achievement for National Grid and is a credit to all involved. It required a great team performance across Electricity Transmission.”
“The project has been progressing on time and under budget since it began in 2011 which is testament to all those involved in the project to date. This has been achieved through close collaboration and innovative working both internally and with our contract partners.”
