National Grid is committed to working with and supporting the local communities around its project sites. London Power Tunnels (LPT) is a seven-year, £1 billion project, to rewire South London via 32.5km of deep underground tunnels, which will help keep Londoners connected to safe and reliable electricity supplies for decades to come.

Once completed, the project will deliver a range of key benefits, including:

  • Less disruption during construction as the majority of works will take place deep underground
  • Future repairs and maintenance work can be carried out without disrupting traffic, residents and businesses
  • Additional cables can be installed in the tunnels to meet future demand

To support communities around the LPT project, National Grid and our partners are delivering:
