Murphy Secures UK’s Largest Substation Contract in Strategic Partnership with National Grid
Murphy has been awarded the UK’s largest active substation contract by National Grid Electricity Transmission (NGET), marking a significant milestone in the development of the country’s electricity infrastructure. The multimillion-pound project involves the construction of a new substation at Uxbridge Moor in Buckinghamshire, adjacent to the existing Iver substation, and will play a crucial role in reinforcing the electricity supply in west London.
The scope of the project includes the design and construction of both 400kV and 132kV substations, underground cabling, associated ancillary buildings, and extensive modification works to the existing overhead transmission network. A key element of the civil works is the development of a 1.2km raised access road from the A412, along with a new bridge over the River Alder Bourne to improve accessibility and minimise disruption during construction.
Murphy will utilise its direct delivery model and in-house expertise to manage all aspects of the project. The inclusion of gas-insulated substation (GIS) technology is a notable feature, offering a significantly reduced site footprint up to 70% smaller than conventional substations helping to limit environmental impact and optimize land use.
The 132kV substation will be connected via underground cables, providing a more resilient and less visually intrusive integration with the national grid. These design choices reflect a commitment to sustainability, innovation, and long-term performance.
Liam Corr, Managing Director of Energy at Murphy, commented: “We are proud to be delivering this critical infrastructure project in partnership with National Grid. Our role in strengthening London’s electricity network underscores Murphy’s ongoing commitment to delivering integrated, future-ready energy solutions across the UK.”
As the UK continues its transition to a more sustainable and electrified future, this project serves as a key investment in energy resilience, enabling reliable power supply for growing communities and supporting national net zero ambitions.
