UK, London: SSEN has launched a $7.3 M (£5.4 M) investment to upgrade its Southfield Road substation in Ealing, West London. The project will enhance electricity network capacity, helping meet rising local energy demands while supporting economic development and decarbonisation goals.
The substation, which currently serves around 20,000 customers, will receive two new high-performance transformers, built offsite by contract partner OCU Group. These will be installed within the existing substation footprint in a staged sequence, carefully planned to minimise disruption to nearby residents and businesses.
Phase one focuses on enabling works, including the removal of redundant structures, with the main electrical installation scheduled for Autumn 2024. The project is expected to be completed by Summer 2026.
Matthew Carter, Project Manager at SSEN, said the upgrade is vital for building a safe, resilient, and future-ready energy infrastructure that can accommodate growing demand and support technologies such as solar panels, electric vehicles, and heat pumps.
Senior Project Manager Joseph Hurling highlighted that the Ealing upgrade is part of a $100 M (£75 M) investment programme aimed at reinforcing West London’s electricity network. These improvements will ensure a more flexible, secure, and low-carbon power supply for years to come.
