Supporting future energy use in London

In February 2011 National Grid embarked upon a seven-year project to rewire the capital via deep underground tunnels, in order to meet increasing electricity demand.
The London Power Tunnels project will create a new 32km electricity superhighway deep below the capital, which will help keep Londoners connected to safe and reliable electricity supplies. The project is due to be complete and fully operational in 2018.
Explore this site to find out more about the project and its progress across the capital.
