Eltham-Headhouse-768x532

HOCHTIEF is working in joint venture to deliver Package 5 of the London Power Tunnels Phase 2 (LPT2) project. The works involve delivering the mechanical and electrical (M&E) works and headhouses for the second phase of National Grid’s scheme to rewire the capital and replace existing electricity cables which are coming to the end of their life.

Key features:

  • M&E/ventilation installation
  • 7 new shaft headhouses
  • Access staircases

HOCHTIEF Murphy Joint Venture is already working on Package 2 of the scheme – Tunnels and Shafts – which involves building a new network of cable tunnels, 32.5km in length, and seven new shafts between Wimbledon and Crayford in South London.

Package 5 will see us deliver the M&E for the scheme and seven new headhouses at key locations along the tunnel route. The headhouses will sit over the new shafts, providing access to the tunnel and containing ventilation and tunnel control systems.

LPT2 follows on from National Grid’s original London Power Tunnels project (LPT1), a seven-year £1 billion scheme to build 32km of tunnels and two new substations. Work on LPT2 began in spring 2020 and will take six years to complete.
