Overview
Waltham Cross substation will be expanded in order to enable the delivery of a new 10 bay substation extension. This extension will increase the capacity of the substation, allowing it to handle more power and distribute it efficiently to homes and businesses. This upgrade is a key part of modernisng the electricity network to support the substation to operate at a higher voltage, enhancing network stability and future-proofing the infrastructure to accommodate growing energy needs.
The eastern 275 kV substation will be demolished as part of the works. In addition, new tower installations and the removal of existing towers will be necessary. We will also be making improvements to the car park that adjoins the site and is frequently used by anglers.
Initial vegetation clearance has been undertaken with the lay down being created in Autumn 2024. We will look tominimise the impacts on Lee Valley Park users and will work closely with the Lee Valley Regional Park Authority throughout the duration of the works.

Community involvement
We are committed to engaging with communities to ensure the projects deliver other localised benefits, including social benefits via our Community Grant Programme and environmental benefits via biodiversity net gain (i.e., increasing biodiversity in the area we are operating in above what is currently there).
The Community Grant Programme is run by the National Grid Electricity Transmission (NGET) business. The programme is aimed at community organisations and charities in areas where our work is impacting local people through our operations and construction activities.
Communities impacted by the maintenance of existing infrastructure (e.g. refurbishment of overhead lines or substations resulting in road closures and other impacts) can apply for grants of up to £10,000.
