HumeLink 500 kV. East and West.

500 kV. Both sides of the line. Tender-stage design with Acciona on HumeLink East. Detail design with UGL on HumeLink West - the alpine section. Transgrid’s nation-critical link between Snowy 2.0 and the Sydney load.

TenderDesign with Acciona - HumeLink East (Bannaby–Wondalga, awarded to the Acciona–GenusPlus JV)
DetailDesign with UGL - HumeLink West (Wagga Wagga–Maragle, UGL–CPB JV) - alpine VTM strain towers to 74.2 m and 150 tonnes

HumeLink is Transgrid's 500 kV backbone - the transmission link that lets Snowy 2.0 actually reach the people who use the power. East runs toward Bannaby. West runs through the alpine country. APD designed both.

The tender pack was with Acciona. The issued-for-construction 500 kV transmission design is with UGL - structural, civil and conductor packages for the heavy tension and terminal towers, including the VTM family used on HumeLink West.

That is the scope. Not the whole corridor. Not the contractor story. The towers, on both sides.
