Cable decommissioning project description
As our cable replacement project is coming to an end, we are planning to decommission the old electricity cables between Beddington and Rowdown, approximately 12km in length. This project is an investment of £6 million to remove old cables no longer needed to supply electricity in London.
The cables, which have reached the end of their useful life, are being replaced in the operational Croydon Cable Tunnel. This is part of a new network of electricity cable tunnels in the Capital designed to accommodate growing demand across London and the South East.
This project is part of National Grid’s wider investment programme into supporting London’s growth. The safe decommissioning of these existing cables will ensure London has a safe and secure electricity transmission network into the future.
The decommissioning project is expected to start in May 2021, and the entire programme will take approximately ten months to complete.
Vegetation management is due to take place in April at some sites along the route in preparation for the decommissioning work.
We will provide more information about other work for the decommissioning project before commencement.
Please note, this work will not affect electricity supplies in the area.
Upcoming work – vegetation management
Before we begin working on the cables, we need to carry out some vegetation management, so our team has space to do their job safely. We have carefully planned the project to minimise disruption to the local community. We are working closely with local authorities to coordinate our activities.
JSM, the contractor working on our behalf, is due to be carrying out vegetation management in the following locations from April 2021. The timing and locations may be subject to change due to site and weather conditions and consents from landowners:
- The footpath linking Croham Valley Road to Broadcoombe
- The rail track next to Guildford Way
- The pathway connecting Broadcoombe to Farnborough Avenue
- Between the gate leading to the private road off Mickleham Way and the Rowdown substation
- In the field at the corner between Huntingfield and Falconwood Road
- Between Fieldway Tram Stop and Addington Court Golf Club
Please be assured we will do all we can to minimise any disruption. We may need to temporarily close or fence off areas for the public’s safety and our workers as we trim and remove the vegetation. You may notice some noise as we do so. Our workers will need to park their vehicles near the site but will make sure they do not impact your access or block anyone in.Bird nesting season has now begun. To ensure we protect birds and their nests, a qualified individual will undertake a nesting bird check 48 hours before any tree trimming works.
The cable replacement and decommissioning works are expected to be completed by early summer 2022.
