Our new multi-million project in part of West London will enhance network capacity in Ealing, helping support local decarbonisation and economic growth.
The £5.4 million substation reinforcement project, which is set to begin this month, will involve the installation of two new transformers at our Southfield Road substation. These will be built offsite by our contract partner, OCU Group.
Upgrading your network while minimising disruption
Using the space within the existing substation site, the transformers will then be connected in a staged sequence to minimise disruption.
Running until Summer 2026, the first phase of the project will focus on enabling works, including the demolition of redundant buildings (you can see the site being prepared for these structures' removal above), before the main electrical works get under way in Autumn of this year.
The new equipment will boost the substation's capacity to meet future demand and support growth from people seeking to generate their own electricity. This substation currently serves approximately 20,000 customers, who will benefit from a more resilient power supply.
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.”
This substantial upgrade is scheduled for completion in Summer 2026, and forms part of a wider programme of works in West London to reinforce the power infrastructure in the region. This project is one of many planned upgrades aimed at future-proofing the network and supporting the transition to low-carbon technologies like EVs, solar panels, and heat pumps.
