We are carrying out work at National Grid’s existing Chilling Lane site as part of a larger scheme to connect the electricity systems of the UK and France. Connecting the electricity systems provides diverse sources of electricity and helps to keep supplies secure and affordable.
The new substation at our Chilling Lane site will be connected to the converter station at Daedalus via underground cables. The substation will allow the power from the interconnector via the converter station to be fed into the national transmission network.
We have agreed the external design and appearance of the operational control buildings with the Local Planning Authority (LPA) to minimise any visual impact from the site. The site will be an outdoor Gas Insulated Switchgear (GIS) substation, within the boundaries of the existing site. All new equipment at site will be lower than or the same height as the existing overhead line gantries there.
