Helicopters remove 150 tonnes of decommissioned transmission line


Powerlink has successfully removed a 50-year-old transmission line traversing the hilly terrain of the Mt Stuart area in north Queensland from the air.

The 11km section of transmission line, originally built in 1963, was decommissioned as it was not cost-effective to refurbish. A new replacement transmission line has been established between Ross and Townsville South Substations to maintain electricity transmission services in the area.

It took 79 helicopter lifts of approximately two tonnes of material each, to completely remove the transmission line structures, which connected the Ross Substation and the Townsville South Substation.

Powerlink chief executive Merryn York said given the challenging terrain and access restrictions, a helicopter was the safest and most effective way to remove the structures.

“Ensuring the reliable supply of electricity through our transmission assets is critical for Powerlink. We are constantly reviewing our transmission network to deliver the best outcomes for Queenslanders,” she said.

“Many of the transmission towers were within Australia Defence Force’s Mount Stuart Training Area, or crossed state government land, requiring access protocols and approvals to enable the work to take place.”
