Enerven delivered critical upgrades to a 275kV transmission line, utilising bare hand live line techniques to ensure minimal disruption while reinforcing ElectraNet’s transmission network for greater resilience.

The customer

ElectraNet plays a vital role in South Australia’s electricity supply chain, delivering safe and reliable energy solutions to homes and businesses, including regional and remote areas. With a focus on asset and project management, ElectraNet’s transmission network underpins electricity delivery across the state.

“This project highlights Enerven’s expertise in live line work, combining innovation and precision to strengthen South Australia’s transmission network without compromising reliability.”

The opportunity

Following s severe storm in 2016 that brought down several transmission towers, ElectraNet identified the need to reinforce its infrastructure to prevent similar incidents in the future. Enerven was engaged to upgrade a 300-kilometre section of 275kV transmission line between the Para Substation and the Davenport Substation.

The project scope included:

  • strengthening transmission towers
  • replacing cross arms and extending tower waists
  • installing mid-span poles to enhance stability
  • performing all works on live lines using bare hand techniques to avoid disruptions to the power supply.

The solution

Key services delivered by Enerven:

  • bare hand live line work: enabled the team to safely perform maintenance and upgrades on live 275kV transmission lines, ensuring uninterrupted electricity delivery throughout the project
  • tower reinforcement: strengthened towers with cross arm replacements, waist extensions, and structural reinforcements to improve resilience against extreme weather events
  • mid-span pole installation: enhanced stability and minimised line sag across critical spans to mitigate future risks
  • remote work capabilities: deployed advanced tools and techniques to perform upgrades across challenging terrain along the 300km transmission line corridor.

Enerven’s skilled team used specialised equipment and rigorous safety protocols to execute this complex project efficiently, ensuring the upgrades met ElectraNet’s high standards for reliability and resilience.
