Loganlea to Jimboomba Network Upgrade
Logan, one of South East Queensland’s fastest growing areas, has been identified to benefit from an additional 110kV powerline.
The 22-kilometre network upgrades is predominantly overhead powerlines from Loganlea Substation on Meakin Road, Loganlea to Jimboomba Substation, located on Camp Cable Road, Jimboomba.
The proposed 110kV powerline will help provide additional security and reliability to the electricity supply to the broader Mount Lindesay, Jimboomba and northern Beaudesert areas, including any future developments in Flagstone and Yarrabilba.
Proposed route
We propose to construct a new 110kV powerline between Kingston Substation at Chambers Flat Road and Jimboomba Substation at Camp Cable Road.
The proposed new powerline would connect to an existing 110kV powerline that runs between Kingston Substation and Loganlea Substation.
The proposal involves constructing concrete poles averaging 22 metres tall along the majority of the route, spaced an average of 200 metres apart.

Where is the proposed corridor?
The initial 2.5km section between the existing Powerlink owned substation on Meakin Road, Loganlea and an existing ENERGEX substation on Chambers Flat Road, Kingston, already contains infrastructure capable of supplying the forecast increase in demand.
No further construction is required, however it will be part of the approval process to show the entire line.
The corridor for new construction leaves Kingston Substation then traverses Kingston Road and Logan Reserve Road, then following the new proposed alignment, straight through to the end of Glen Road.
The corridor then crosses the Logan River at Anzac Avenue, and heads south on Waterford-Tamborine Road to join an easement containing an existing 33kV powerline.
The corridor follows this easement, crossing over Hotz Road and existing electricity infrastructure before crossing Camp Cable Road and continuing west to Jimboomba Substation.
The proposed corridor as outlined in the Final IAR was determined following consultation with the community on the IAR and Supplementary IAR.
Based on feedback received during initial stakeholder consultation, we made some changes in the northern section of the corridor.
These changes were detailed in the Supplementary IAR, which we voluntarily released for public comment on 17 March 2010.
The route selection process is detailed further in archived information.

Final IAR
Consultation has now closed on the Final IAR. We would like to thank everyone who took the time to make a submission.
Formal submissions were accepted from 21 June 2010 to 9 July 2010.
IAR conclusions
Consultation on the IAR
In June 2009, we released the IAR for public comment, as part of our obligations under the Community Infrastructure Designation (CID) Process.
The IAR informed the community of the project and provided information about work undertaken by ENERGEX to identify and address social, environmental and economic issues relating to the project.
We received 72 submissions on the IAR from a range of stakeholders including affected landowners, local residents, the wider community, Logan City Council and government agencies.
The response to the project helped to formally identify the main issues of concern relation to the project, including:
- route selection
- property values
- health and safety (including electric and magnetic fields, and the safety of poles along the Logan River)
- short and longer term impacts on the environment, especially along the Logan River
- vegetation management and tree clearing
- visual amenity
- impacts on local wildlife
- the consultation process
Consultation on the Supplementary IAR
In March 2010, we released the Supplementary IAR for community consultation.
This was not part of our requirements under the CID process but an additional, voluntary consultation activity.
This ensured the community was able to provide feedback to us about changes to the route corridor resulting from comments received on the IAR in mid-2009.
We received 59 submissions on the Supplementary IAR from a range of stakeholders along the corridor route.
More information about the outcomes of this consultation on the IAR and Supplementary IAR is available in Chapter 17 of the Final IAR.
Consultation on the Final IAR
From 21 June to 9 July 2010, we released the Final IAR for community consultation.
This was the final formal consultation activity for the project and part of our legislative requirements under the CID process.
During consultation, more than 100 submissions were received about the project from a range of stakeholders.
The Final Assessment Report was released in late 2010 and has now been submiutted to the Minister for government approval.
How has ENERGEX used the feedback received?
All members of the community who made a submission have received personal, detailed responses.
In response to the IAR feedback received, we conducted further investigations to help address the issues and concerns raised by the community.
We produced a further report - the Supplementary IAR - which outlines the changes made in response to community feedback.
It lists the potential impacts and mitigation measures specific to the revised section of the corridor.
We have undertaken additional environmental studies and looked for opportunities along the preferred corridor to make improvements that would further mitigate concerns.
As a result, we plan to make some changes to the proposed powerline corridor, including reducing the impact on the number of properties directly affected, the number of river crossings and the alignment of the proposed powerline along Logan River
Feedback received during consultation on the Final IAR is currently being assessed.
How has the proposed corridor route changed?
Following consultation on the IAR, the preferred corridor route was altered between Logan Reserve Road and Glen Road.
There will now be an additional 3.5 kilometres of underground construction, removing the impact on 24 properties and two crossings of the Logan River.
This altered corridor forms the proposed corridor route for the project, reported in the Final IAR.
The first 2.2 kilometres of the chosen route was planned as underground construction because there was no room to build it overhead with the existing electricity assets in the area.
While we maintain the original proposal would not have a detrimental impact on the Logan River, we acknowledge the value placed on the river by the local community.
With this in mind, we have now committed to continuing the underground construction for another 3.5 kilometres to the end of Glen Road into unformed road reserve.
Glen Road presents a unique opportunity along the route where a suitable, straight road reserve exists to contain the construction.
The balance between the additional overhead cost is largely neutralised by the alternative easement acquisition costs, and complex overhead construction costs in this particular area.
The additional underground component now proposed has a number of advantages:
- It removes two crossings of the Logan River.
- It removes one third of the river component of the project.
- The need for an easement across 22 properties is removed, reducing the number of landowners directly affected by the project by nearly 25 per cent.
- It is relatively cost neutral to ENERGEX, this is important because infrastructure costs are passed on to consumers in the price of electricity.
- It allows us to proceed with an important powerline corridor, which is essential to maintaining a safe and reliable supply of electricity to the area.
What happens next?
In late 2010, ENERGEX produced a Final Assessment Report (FAR) for the project.
The FAR included all submissions made during consultation on the Project, including for the Supplementary IAR.
The FAR has now been submitted to the Minister for Energy and Water Utilities for consideration of the project, prior to designation and construction approval.
