ACCIONA, together with its local partner Genus, has begun using helicopters to string conductors on the HumeLink East transmission line in Australia.

The transmission line is one of the country's largest energy infrastructure initiatives. The project involves the design and construction of 225 kilometers of 500 kV overhead transmission lines from Bannaby to Wondalga, as well as the upgrade of the 500 kV Bannaby substation.

The contract, awarded by Australian company Transgrid, also includes the construction of 459 transmission towers that support more than 6,000 kilometers of conductor. The project's main objective is to reshape the region's electricity market, strengthen grid stability and facilitate the transition to new renewable energy sources.

At HumeLink East, ACCIONA is using helicopters for conductor stringing, a safer and faster method. This method also has less impact on landowners and local communities than traditional ground-based methods, which involve using excavators and other ground equipment between transmission towers.

Construction continues to advance through the use of new techniques. The project is creating more than 1,600 jobs throughout its construction phases. The first transmission tower was erected in January 2026, followed by the 100th tower in July 2026. Once completed, the transmission line will help provide a more affordable, reliable and sustainable electricity supply by increasing the capacity to deliver clean energy to millions of consumers.
