  • The Project
    TransGrid is proposing to install a steel lattice radio repeater pole (approximately 95 metres in height) at the Sunnydale property located along the Silver City Highway, south of Broken Hill, NSW. 
    Key elements of the proposed activity include:
    • Installation of a steel lattice telecommunications structure up to 95 metres in height
    • Guyed wires to support the structure extending up to 100 metres outwards from the centre point of the structure
    • Two Yagi antennas installed on the radio repeater tower

  • Why is TransGrid Undertaking the Work?

    ​The proposed activity is needed to improve the strength and reliability of electricity supply to the area through efficient communication to the Broken Hill substation. 

    There is an obligation under the Electricity Supply Act 1995 for electricity suppliers such as TransGrid to provide appropriate maintenance of electricity facilities and to facilitate rapid and efficient response to any emergencies. Control and protection of these assets is remotely managed, with data communication necessary for the safe and efficient operation of the network. This is predominantly provided by a telecommunication network comprising microwave radio and optical ground wire based assets. 

  • Planning Approval and Environmental assessment
    Approval for the project is being sought under Part 5 of the Environmental Planning and Assessment Act 1979. TransGrid prepared a Review of Environmental Factors (REF), and the REF was made available for public and stakeholder comment from 20 March to 17 April, 2019.
    To view the REF, please click on the link below. 
    TransGrid is now considering all submissions and will then prepare a Submissions Report to address the submissions received. TransGrid will consider all submissions as part of the project approval process. Should the project be approved, a copy of the Submissions Report and Decision Statement will be made available on the website.
