The multimillion-pound contract from National Grid Electricity Transmission (NGET) will see the construction of a new substation at Uxbridge Moor, which borders NGET’s existing Iver substation in Buckinghamshire, connecting new customers to the electricity network and helping to meet the significant increase in demand for electricity to the west of London.

With its wide-ranging inhouse expertise and direct delivery approach, Murphy will be carrying out the broad scope of works itself – including the construction of a new 400kV substation, a new 132kV substation, ancillary facilities, underground cabling and associated modification works to the 400kV overhead line network to the new 400kV substation. Connection to the new 132kV substation will be via 132kV underground cables.

The scope also consists of a new 1.2km raised access road off the A412 and other associated civil infrastructure, including a new road bridge crossing over River Alder Bourne.

The substation design is gas insulated, this advanced technology will allow the team to reduce the footprint of the proposed site by around 70% compared to a traditional substation design, minimising the impact on the local area and the environment.

Liam Corr, Managing Director of Energy at Murphy, said; “Since 1951 Murphy has been a leading provider of innovative and integrated energy solutions – today we support groundbreaking transmission and distribution projects across the four countries in which we work.

“We are proud to be delivering this project in the UK’s capital and building on our strong working relationship with National Grid to help to ensure energy security for decades to come.”

Laura Mulcahy, project director at National Grid Electricity Transmission, said:

“Our new Uxbridge Moor substation will provide vital access to power for data centres that are at the heart of Britain’s innovation and economic growth. It will enable new jobs and investment in Buckinghamshire, and will support the UK’s digital future.

“Alongside these significant benefits, we are working to keep the substation’s environmental impact to a minimum. By using the latest SF6-free gas-insulated switchgear, we’re reducing the size of this crucial site by around 70%, and ensuring its technology is sustainable and resilient long into the future.”
