A new 275kV transmission line between the Western Downs Substation (near Kogan) and the Halys Substation (near Tarong) is needed to ensure a reliable supply of high voltage electricity is maintained to Southern Queensland.
About 80% of the new line is being constructed on existing vacant easements between Halys and the Condamine River near Warra. These double-width easements were acquired by Powerlink in the late 1990s as part of our future planning, and currently contain one 275kV transmission line with sufficient space to safely construct the second line. New easements were required for about 25km of the new line (between the Western Downs Substation and Warra).
Construction is under way and is expected to be completed by Summer 2013/14. The new line is similar in size and appearance to the existing steel tower line which crosses the Warrego Highway near Warra.
In 2009, Powerlink appointed specialist environmental consultant RPS (formerly Conics) to undertake an Environmental Impact Assessment (EIA) for the project.
As part of the EIA, RPS prepared an Environmental Impact Statement (EIS), following input from the community and other stakeholders. The Final EIS was published in November 2010 and included an Environmental Management Plan (EMP) to guide construction activities.
