Yass to Murrumburrah line uprating


TransGrid proposes to uprate its existing transmission line 99M Yass to Murrumburrah (Line 99M).

  • Proposed Activity

    ​TransGrid proposes to uprate its existing transmission line 99M Yass to Murrumburrah (Line 99M). This involves replacing existing conductors along a section of the line between Structures 1 and 143. Key elements of the proposed activity involve:

    • Re-stringing of the existing conductors.
    • Replacement of the existing overhead earth wire with optical ground wire (OPGW).
    • Refurbishment or replacement of approximately 34 structures.
    • Connections and renewal works at the Yass 330kV Substation (as required).

  • Why is TransGrid undertaking the work?

    ​The NSW Government has approved the construction and operation of the Coppabella Wind Farm, located approximately 30km west of Yass NSW. The Coppabella Wind Farm requires connection to the electricity grid and, to achieve this, TransGrid proposes to uprate a section of the existing Line 99M, between Yass and Murrumburrah (the proposed activity). Uprating Line 99M will enable the increased load requirements from Coppabella Wind Farm to be met and will also maintain a safe and reliable electricity supply.

  • Planning Approval and Environmental Assessment

    ​Approval for the proposed activity is being sought under Part 5 of the Environmental Planning and Assessment Act 1979. TransGrid is in the final stages of completing a Review of Environmental Factors (REF), which will be placed on TransGrid’s website in the coming weeks. The REF will be available for public and stakeholder comment for a period of 20 business days from the date it is placed on the website.

    Following the exhibition of the REF, a Submissions Report will be prepared to address the submissions received. TransGrid will consider all submissions as part of the approval process. Subject to determination of the proposed activity, TransGrid anticipates that it will commence construction works mid-2018 and complete the works within the first quarter of 2019.
