Two months and two milestones for National Grid team members and the Hochtief Murphy Joint Venture (HMJV) for the London Power Tunnels  2 (LPT2) project.  

On the 23/07/2022 the Lovat TBM Caroline completed her journey from Brixton to Wimbledon. Topping out at 61.1m in a 16hr day along her 5.7km leg. Now there is 18.5km complete with another 14km to go!  

Back on the 21/06/2022 the first of five drives by four TBMs at Eltham were celebrated!. The 140-t Herrenknecht TBM, named Christine after Christine Townley, the former Executive Director of the Construction Youth Trust, known for her championing of diversity and STEM careers, began its journey at the LPT site in Hurst in July 2021. In total, it has travelled 6.7km from Hurst to Eltham underneath London, reaching depths of up to 50m underground in the process.  

National Grid’s two other TBMs Edith and Grace continue their tunnelling work deep underground across sites in South London.  

The completion of the drives represents a key moment for the GBP1 billion project to rewire London and prepare it for future electricity demands as the city continues to grow. LPT is a crucial infrastructure project that will ensure people living in Eltham and Londoners more widely can continue to access safe and reliable electricity supplies. LPT is currently under-budget and on time.
