The Challenge

Genus was engaged to complete the final connections and interconnections associated with new high-voltage reticulation infrastructure at BHP’s Yandi operations.

Western Australia Iron Ore (WAIO) is an integrated mining system comprising four processing hubs and five mines, connected by more than 1,000 kilometres of rail infrastructure and port facilities across the Pilbara region of Western Australia.

At the Yandi mine, relocation of the high-voltage network required installation, testing and energisation activities to integrate the new infrastructure and support continued operations.

The project required specialist HV expertise together with testing, commissioning and regulatory management activities to safely prepare the infrastructure for energisation.

The Genus Approach

Genus was engaged to provide high-voltage cable terminators and specialist testing technicians to support installation and testing activities associated with the HV network relocation.

The works supported final connection and energisation of the relocated electrical infrastructure.

The project extended beyond testing and commissioning activities, with Genus also providing project delivery, stakeholder coordination and regulatory support throughout execution.

Delivery in action

Genus delivered testing, installation and energisation activities associated with the relocated HV network.

The scope includes:

  • 33kV terminations for parallel supply infrastructure
  • Installation of 33kV high-voltage cable
  • Testing and commissioning of HV cables and power line infrastructure
  • Primary and secondary injection testing of new relay feeder panels
  • Earth testing activities including:
    • Step and touch testing
    • Fall of potential testing
    • Continuity testing

The project also included:

  • Project delivery management
  • Customer liaison activities
  • Regulatory consultation
  • Permit management
  • Project completion and handover activities
The outcome

The project was successfully completed with works extending beyond testing and commissioning into full project delivery support.

The project concluded with provision of the required safety certificate, enabling the infrastructure to proceed to energisation.

The completed works supported relocation and integration of the new HV network infrastructure at Yandi operations.
