Loganlea to Jimboomba network upgrade
Residential and commercial growth in South East Queensland and an increased demand for energy has led to a sharp rise in electricity consumption. As a result, the region’s existing electricity supply is reaching capacity.
To meet increased demand, ENERGEX has embarked on a five year, $4 billion investment program across South East Queensland. This investment will reinforce the network and provide a more reliable and safe supply of electricity to residents and businesses.
It is proposed that Logan, one of the region’s fastest growing areas, should benefit from this investment program.

what is the Loganlea to Jimboomba network upgrade?
The proposed Loganlea to Jimboomba network upgrade is an approximately 22 kilometre, 110,000v (110KV) powerline of predominantly overhead construction from Loganlea Substation on Meakin Road, Loganlea to Jimboomba Substation, located on Camp Cable Road, Jimboomba.
The proposed new 110kV powerline will, if constructed, help provide additional security and reliability to the electricity supply to the broader Mt Lindesay, Jimboomba and northern Beaudesert areas.
what will the network upgrade involve?
ENERGEX proposes to invest in and 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 22m tall along the majority of the route, spaced an average of 200m apart.
supplementary IAR available for public comment
Released on 17 March 2010, the Supplementary IAR details all information about the proposed corridor route change to the northern end of the alignment. The community is encouraged to provide input to ENERGEX about the changes identified in this report.
supplementary IAR– 17 march 2010 (24.5mb)
Hard copies of the supplementary IAR is also available for viewing at the followign Logan City Council libraries:Formal submissions on the Supplementary IAR will be accepted until at 5:00pm on Thursday 8 April 2010.
where is the proposed corridor?
Based on feedback received during consultation on the proposed corridor route specified in the Initial Assessment Report (IAR) for the project, there have been some changes in the northern section of the corridor that are detailed in the Supplementary IAR which was released for public comment on 17 March 2010.
The initial 2.5km section between an 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. This section will form part of the approvals process applicable to the entire line, but will require no new construction.
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.

what are the results of consultation on the IAR?
In June 2009 ENERGEX released an IAR for public comment, as part of ENERGEX’s 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. ENERGEX 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 in 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, and
- the consultation process.
how has ENERGEX used the feedback received?
ENERGEX has analysed all IAR submissions and comments received in relation to the project and has conducted further investigations to help address all issues and concerns raised. All members of the community who made a submission have received personal detailed responses to their submission.
ENERGEX has also produced a further report - Supplementary IAR - which outlines the changes made in response to community feedback and lists the potential impacts and mitigation measures specific to the revised section of the corridor.
ENERGEX has undertaken additional environmental studies and looked for opportunities along the preferred corridor to make improvements that would further mitigate concerns. As a result, ENERGEX plans 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 the Logan River.
how has the proposed corridor route changed?
Following consultation on the IAR, the preferred corridor route has been altered between between Logan Reserve Road and Glen Road. There will now be an additional 3.5kms of underground construction, removing the impact on 22 properties and two crossings of the Logan River.
The first 2.2 kilometres of the chosen route was always planned as underground construction, simply because there was no room to build it overhead with the existing electricity assets in the area.
While ENERGEX maintains 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, ENERGEX has 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, and 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 as it:
- removes two crossings of the Logan River
- removes one third of the river component of the project
- removes the need for an easement across 22 properties overall, effectively reducing the number of landowners directly affected by the project, by nearly 25 per cent
- is relatively cost neutral to ENERGEX when considering the alternative complex overhead construction in this particular section, and the reduced easement cost - this is important because infrastructure costs are passed on to consumers in the price of electricity
- allows ENERGEX to proceed with an important powerline corridor, which is essential to maintaining a safe and reliable supply of electricity to the area, while further addressing community concerns.
what happens next?
ENERGEX released a Supplementary IAR for public comment on 17 March 2010. [Paragraph continues] The Supplementary IAR covers similar topics as the first IAR, but focuses on the changed section of the route (the area around Glen Road).
Prior to the release of the Supplementary IAR, ENERGEX wrote to everyone registered on our Loganlea to Jimboomba project database to let them know when and how to make a formal submission on the Supplementary IAR. The report’s release was also advertised in local newspapers.
