Rather than relying solely on Loganlea substation to supply homes and businesses from Browns Plains to Beaudesert, VETO believes a local 275/110kV substation is required to support predicted growth for our Logan community.
The Energex map (below) shows that Energex expects the majority of future growth for our community to occur in the Greenbank, North Maclean and Greater Flagstone area. The “fully developed” load for Greater Flagstone of 160 MVA is equivalent to 50,000 homes, whereas the “fully developed” load for Yarrabilba of 74 MVA is equivalent to 23,000 homes.

This Energex map (dated 25 August 2011) was provided by Mr John Wallace, the Oakley-Greenwood consultant reviewing the Yarrabilba alternative for Minister Stephen Robertson. The map may have been prepared by Energex to further undermine the Yarrabilba substation alternative proposed by Cardno for the Logan City Council. However it does highlight:-
- The reliance on the Loganlea Powerlink 275/110kV injection point (substation) as the sole source of electricity supply for communities from Browns Plains to Beaudesert, including Jimboomba, plus the planned high growth communities of Greater Flagstone and Yarrabilba;
- The Energex claim that Greenbank is “Unsuitable for a 275/110kV injection point”, when this 68 ha Powerlink substation site was originally justified as being “well located for efficient distribution of high-voltage electricity”;
- The need for one or more local Powerlink 275/110kV injection points (substations) nearer to the planned high growth communities in Logan.
The major Greenbank substation is actually shown within the 'circled' highest growth area of Greater Flagstone and needs to be reconsidered as a local 275/110kV injection point.
Greenbank will also be needed to support the planned electrification of the rail line to Beaudesert as well as expected growth in the Beaudesert and Bromelton area.
Energex attempts to justify their proposed second Loganlea to Jimboomba high voltage power line, continue to highlight gaps in their planning process. A long term Strategic Plan with genuine stakeholder engagement to fully assess all options is needed to support the two high growth communities planned for Logan (Greater Flagstone and Yarrabilba) as well as our existing adjacent communities.
