Proposed transmission projects to connect Queensland

High-voltage transmission company Powerlink Queensland will commence a number of transmission lines and substation projects in the Surat Basin to facilitate the expansion of the energy and resources sector and townships in the region.

One of these projects is a 275kV transmission line between Columboola and Wandoan South and establishment of a 275/132kV substation at Wandoan South. Powerlink has been asked by coal seam gas explorer and producer QGC to identify easements and construct a short 132kV transmission line between Wandoan South substation and QGC’s Woleebee gas processing plant.

Powerlink was also requested by Australia Pacific LNG (APLNG) to supply high-voltage electricity via a new 132kV transmission line between Columboola and APLNG’s three gas processing plants at Condabri.

Powerlink and Ergon Energy have also identified the need for a new 275kV transmission line which would run between a proposed Columboola substation and the Western Downs substation to meet rapid and continuing electricity demand growth in South West Queensland.

Environmental studies for each of these projects have been completed and construction of the Columboola to Wandoan South transmission line, Wandoan South substation and Wandoan South to QGC Woleebee transmission line is expected to start in early 2012.

A new 275kV transmission line between the Western Downs substation (near Kogan) and the Halys substation (near Tarong) is also required to ensure a reliable supply of high-voltage electricity is maintained to southern Queensland.
