HumeLink

HumeLink is a new 500kV transmission line which will connect Wagga Wagga, Bannaby and Maragle.

It is one of the state’s largest energy infrastructure projects, with about 365 km of new transmission lines, and new or upgraded infrastructure at four locations.

Why do we need HumeLink?

To meet our future energy demands, Australia needs to transition to a greater mix of low-emission renewable energy sources, such as wind and solar. HumeLink will deliver a more reliable and more sustainable grid by increasing the amount of renewable energy that can be delivered across the national electricity grid, helping to transition Australia to a low carbon future.

Main construction has now started on HumeLink East and HumeLink West

The main construction works include construction of towers, building the new substations at Gugaa and Maragle, and upgrading existing substations at Bannaby and Wagga Wagga.

Transmission towers will be built in multiple stages from excavating and foundation construction to tower erection, followed by stringing of the transmission lines.

With the approvals in place, HumeLink East began work with the first pile bored near Tumut, while HumeLink West started vegetation clearing works in the Forestry portion of the alignment and is beginning foundation works at Gregadoo, east of Wagga Wagga.

Tower construction on HumeLink West through to the end of the year will progress from Wagga Wagga towards the south of Tarcutta, before progressing east to Ellerslie and Greenhills.

On HumeLink East, there will be multiple work fronts open from October. Work on tower foundations will be pushing north from Tumut towards the Murrumbidgee River. Crews will also be working on access tracks and tower foundations from the Yass area down to the Murrumbidgee River and from Bannaby towards Yass.

Some enabling works – which started in early 2025 – will continue, including access point establishment, access tracks and completion of the Kunama accommodation facility on HumeLink West.

Accommodation facilities at Tarcutta (HumeLink West) and Adjungbilly and Yass (HumeLink East) have been completed and have workers living on site.

Laydown facilities, which include equipment and materials storage, have been established at: Gugaa, Ellerslie, Maragle, Snubba Road and Batlow (HumeLink West), and Yass and Bannaby (HumeLink East).

Following consultation with community and stakeholders, additional laydown areas and concrete batching plant locations are being assessed at Lower Bago Road, Cullinga Park Lane, Honeysuckle Road and Gadara Road.

Community groups within the project footprint have the opportunity to share in funding for projects and initiatives that will bring lasting social, economic, and environmental benefits to the region. The HumeLink Community Investment and Benefits Program, launched on 16 June, is designed to ensure local communities share in the positive outcomes of the project through targeted funding and support.

Transgrid General Manager of Community, First Nations and Social Legacy, Michael Johnson said: “We’re working with local communities to make HumeLink more than a new energy project - we want it to deliver lasting, positive benefits for people and places across the region.

“Thank you to everyone who helped identify the areas of focus for the program, namely community connection, care for country, local education and skills development, local industry development and social legacy initiatives.

Shortlisted projects are currently being assessed by a panel comprising Transgrid and its delivery partners, following community feedback.

More information about the program is available on the Community Investment and Benefits Program page.
