London Power Tunnel 400 / 132 kV, UK

Linxon is supplying the substation package relating to National Grids’ London Power Tunnels 2 project in the United Kingdom. This vital work will help keep Londoners connected to safe and reliable electricity supplies.

In Spring 2020, National Grid embarked upon a six-year, £1 billion project, to rewire South London via 32 km of deep underground tunnels. To connect the underground cables to the Transmission and Distribution Networks, Linxon will design, supply, install and commission connection bays at two existing National Grid substation sites, undertake modification works at two further sites and construct a new 7 bay 400/132kV Gas Insulated Switchgear (GIS) substation at Bengeworth Road to reinforce power supplies to South East London.

As a key enabler for the London Power Tunnels 2 (LPT2) project, Linxon will join National Grid’s Project 13 Enterprise. The Enterprise model aims to boost certainty and productivity in delivery, improve whole asset life outcomes and support a more sustainable, innovative and highly skilled industry.

The National Grid London Power Tunnels 2 project is due to be complete and fully operational in 2026 and will result in less construction disruption during construction and operation as the majority of works and assets are deep underground, yet highly accessible. Additional cables can also be installed in the tunnels to meet future power demand.
