In October 2023 Powerlink completed a project to refit the existing 110kV Rocklea to Sumner transmission line. This line is an essential component of the electricity transmission network supplying the Brisbane metropolitan area.

The line has been in service since 1963 and required refitting to ensure a continued safe, reliable and cost-effective power supply to our community.

The project involved refitting 16 towers along the 5.5km line. Activities included:

  • condition assessment
  • replacing overhead earth wires
  • checking and replacing any corroded nuts, bolts and steelwork
  • restoring and/or upgrading access tracks.

All activities were undertaken in accordance with our Land Access Protocol (LAP) and rigorous environmental management requirements. Powerlink worked with landholders, the community and other stakeholders within the project footprint to keep them informed of our activities and minimise any potential impacts.
