Ingham South Substation Reinvestment Project

Overview 

The Ingham South Substation is an important part of Powerlink’s 132kV transmission network helping to supply electricity to the wider Ingham area and Ergon Energy’s 66kV Ingham Substation.  

The Ingham South Substation Reinvestment Project involves upgrading critical equipment and installing a new control building, designed to Q200 flood levels, to support a safe, secure and reliable electricity supply into the future.  

The project is being delivered in stages over three years with all works expected to be completed by November 2028.  

Status 

The first stage of works commenced in August 2026 and will continue through to mid-December 2026.

These works include delivery of a new control building which will arrive at the substation site in mid-to-late October 2026.

Pilot vehicles and traffic management will be in place to assist with delivery of the 14-metre-long building. Cranes will also be used to install the building on-site.

As some construction activities may take up to 12 hours and must continue once they start, work crews will be onsite between 6am and 6pm, seven days a week.  

Various machinery will be used for the works including forklifts, excavators, cranes and other heavy vehicles.  

We will work to minimise noise and dust impacts to neighbouring properties, wherever possible.  

Following the wet season, the upgrade works  are expected to resume in April 2027. We will continue to keep project stakeholders updated on works and timings as the project progresses.
