Construction has officially commenced on Transgrid’s HumeLink, one of Australia’s most significant energy transmission projects. The project will connect the nation’s largest renewable energy initiative, Snowy Hydro 2.0, into the grid — strengthening Australia’s clean energy network from South Australia to northern Queensland.
Delivered by a UGL and CPB Contractors joint venture, HumeLink will form the backbone of Australia’s east coast power transmission system, linking multiple renewable energy zones and supporting the country’s transition toward a reliable, sustainable energy future.
Major Construction Milestones
The project team has already achieved several key milestones:
- Foundation piling has begun for the first transmission tower, paving the way for the erection of 140 kilometres of transmission towers in the coming months.
- Around 30 access points have been constructed and 70 kilometres of new access tracks upgraded or installed.
- Tower materials laydown areas have been established at Gugaa, Ellerslie, and near Batlow.
- The Tarcutta worker accommodation camp is now complete, with the Kunama facility set for completion in November.
- Construction has commenced on a 500 kV substation at Maragle, enabling Snowy Hydro 2.0 to be integrated into the national grid.
- A new 500 kV substation at Gugaa is also underway, set to become the central hub for power transmission in the Riverina region.
These developments mark significant progress in Australia’s ongoing investment in renewable infrastructure.
“We’re proud to play our role in building Australia’s clean energy future,” said a UGL and CPB Contractors spokesperson. “HumeLink will deliver the essential transmission infrastructure needed to power homes and industries sustainably for decades to come.”
Once completed, HumeLink will improve energy reliability, reduce emissions, and support economic growth by enabling efficient flow of renewable power across states.
