Distribution network operator UK Power Networks has completed a £6.8 million electricity network upgrade between Sutton and Beddington to increase network capacity and support future electricity demand.
The project involved installing 6.8km of new underground cables, helping to maintain reliable electricity supplies for more than 68,000 homes and businesses.
The new infrastructure is also designed to accommodate growing demand as more low-carbon technologies are connected to the electricity network.
Two new 132kV underground cables were installed along a 3.4km route. The work involved excavating trenches, installing cable ducts, and pulling the new cables into position before joining them at intervals along the route.
Part of the project also required deep excavation to connect the new cables to an existing tunnel.
Upgrade increases network capacity
Gbenga Odesola, Project Manager at UK Power Networks, says, “Energisation of these cables marks the culmination of a significant investment in long-term resilience, modernising the network and preparing for future demand, including as more of us connect to low carbon technologies.
“I’m proud of the way our team worked safely and collaboratively to deliver this important investment project. Their commitment has strengthened the network and will help ensure a reliable electricity supply for thousands of customers for years to come.”
TJ O’Keeffe, Construction Manager at Clancy, adds, “This was a complex project, delivered safely through strong teamwork and close collaboration with our client, UK Power Networks.
“Working around live, 132,000-volt cables required care and specialist methods, including vacuum excavation.
“I’m proud of the commitment and expertise that went into delivering this important investment for the local community.”
The project forms part of UK Power Networks’ wider investment programme. The company says it invested more than £800 million across London, the South East, and the East of England last year to maintain and upgrade the electricity network while supporting the transition to lower-carbon energy.
