First two transmission towers erected on HumeLink West

The HumeLink project has reached a significant milestone with the erection of its first two transmission towers at Book Book, near Wagga Wagga. This achievement marks the official start of full-scale construction on the western section of one of Australia’s most critical energy infrastructure projects.

Delivered through a joint venture between UGL and CPB Contractors for Transgrid, HumeLink West brings together industry-leading expertise to deliver a project that will transform the way energy flows across the National Electricity Market.

HumeLink West Project Director Tim Burns said the tower erection is a major achievement for the team and local partners.

“This milestone marks an exciting step forward for our dedicated HumeLink West delivery team,” he said. “Together with our subcontractor businesses and local supply chain, CPB Contractors and UGL are now focused on safely delivering the remaining 360 towers. As we progress, we’ll continue listening and engaging with local communities to ensure they share in the benefits - through jobs, skills and local investment.”

HumeLink is a 365-kilometre transmission line designed to connect renewable energy sources, including Snowy 2.0, to the grid and will feature:

  • Over 800 transmission towers
  • 52,000 tonnes of structural steel
  • More than 9,300 kilometres of high-voltage cabling

Doug Moss, UGL Managing Director, also highlighted the significance of this project:

“The importance of this project really can’t be overstated. We are tying the biggest renewable energy project in the country into the grid for the benefit of all Australians. To be part of that is incredibly exciting, and it sets the benchmark for many more projects like this in the future.”
