Project Outline<\/h2>\n\n\n\n

Working as part of the multi-award-winning Hochtief-Murphy Joint Venture HMJV<\/a>, Murphy is contracted to deliver two major design and construction packages for National Grid as part of their \u00a31bn flagship London Power Tunnels Phase 2 scheme.<\/p>\n\n\n\n

We are replacing the existing cable infrastructure, ensuring the resilience of London\u2019s electricity network. 2023 saw an important milestone with the end of tunnelling works, the completion of all five tunnel drives and the construction of all eight shafts \u2013 all completed with an exceptional safety performance.<\/p>\n\n\n\n

The final breakthrough was achieved in September by TBM \u2018Grace\u2019, having tunnelled over 11km eastwards from New Cross substation in Southwark. This completed the 32.5km of tunnels across South London, with every section handed over on, or ahead of, time and within budget.<\/p>\n\n\n\n

The Tunnels and Shafts package is due to be completed by mid-2024. The works to build the headhouses, which will cover the shafts and provide safe access to the tunnels and high-voltage cables, are already well underway at all our sites.<\/p>\n\n\n\n
