Power Cable Tunnel to link Bexley with Wimbledon

James told of major investment underground to improve reliability of electricity supplies during visit to Hurst Substation in Bexley

National Grid have submitted plans to construct an underground tunnel linking the Hurst Substation in Stable, Lane Bexley with Wimbledon as part of a major upgrade of electricity supply circuits.  James Brokenshire was briefed on the plans during a recent visit to the Hurst facility.  As part of the major investment scheme existing circuits which are coming to the end of their useful life would be replaced with new cabling providing greater reliability and improved accessibility for ongoing maintenance via the tunnel access.  The ‘London Power Tunnels 2’ programme is a significant engineering project requiring specialist machines to bore a tunnel from New Cross to Bexley as part of the next stage of the programme.  Works are expected to commence in 2021 and will take until 2025 to complete.

National Grid have submitted a planning application to Bexley Council outlining the need for a temporary haul road linking the Hurst Substation with the North Cray Road avoiding the need to use Vicarage Road.  60 lorry movements are expected per day once the main tunnelling works have commenced.  During the visit James underlined the need to ensure that any impact on residents is minimised.

Commenting James said:

“This major project will see improved reliability in our power supply system as well as less disruption because National Grid won’t have to dig up roads to do their repairs.  That said, it’s important that great care is taken to ensure these works are conducted safely and with the least disruption to people living in Bexley.  Whilst a haul road will be needed, it’s important that this is temporary and consideration is given to the impact on the North Cray Road which is already congested at peak times.  Given the nature of the tunnelling, I’ve pressed National Grid on the monitoring of the works and the impact on ground conditions.  This is an important investment in our power infrastructure and I welcome the commitments provided by National Grid, but will be keeping a close eye as this significant project progresses.”
