Scottish and Southern Electricity Networks (SSEN) will begin a £5.4 million upgrade to its Southfield Road substation in Ealing later this month, as part of a wider investment in West London’s electricity infrastructure.
The project, due for completion by summer 2026, is designed to boost network capacity and support local decarbonisation and economic growth.
Around 20,000 homes and businesses are expected to benefit from the project, which forms part of SSEN’s investment programme across West London.
Two new transformers will be constructed offsite by contractor OCU Group and installed in stages within the existing substation footprint to minimise disruption to locals. Initial works involve the demolition of redundant buildings, with major electrical upgrades scheduled to start in the autumn.
Matthew Carter, Project Manager at SSEN said: “This reinforcement project is a crucial step in ensuring that our infrastructure can support the growing energy needs of our customers in West London. By installing state-of-the-art transformers, we are enhancing both the safety and capacity of the substation, which will have long-term benefits as we all move towards adopting low-carbon technologies to power our homes, workplaces and public services.”
Joseph Hurling, Senior Project Manager at SSEN added: “We’re delighted to see this project begin at the Southfield Road Substation, which is part of a £75m investment programme in our West London electricity network. By upgrading the capacity and technology in our substations and distribution network, we can capture more green energy and power communities and growth with a secure, flexible and resilient electricity supply long into the future.”
