Overview
Under the National Electricity Rules, Powerlink is required to ensure system strength services are available to Queensland’s transmission network. This will be achieved through the System Strength Project.
As part of this project, Powerlink will install a synchronous condenser at the Stanwell Substation to stabilise and strengthen the power system as the energy generation mix in Queensland evolves.
Status
In April 2026, Powerlink announced a synchronous condenser will be installed at the Stanwell Substation.
The Stanwell Synchronous Condenser will be one of four synchronous condensers installed in Central Queensland by 2029.
The Stanwell Substation was chosen following detailed network analysis and consideration of social, environmental and economic factors.
In March 2026, Powerlink signed an agreement with Hitachi Energy to supply and install the synchronous condenser.
The following infrastructure will be installed:
- large shed with lightning masts
- synchronous condenser (inside shed)
- control room
- step-up transformer
- auxiliary transformer
- back-up generator
- outdoor cooler.
Initial engagement will occur with the broader Stanwell community and other local stakeholders throughout April and May 2026.
Get involved
Local and Indigenous participation
Powerlink is using a coordinated, program-level approach across our Central Queensland projects to maximise opportunities for local and Indigenous businesses.
For this project, we are working with our experienced supplier panel to appoint contractors for the design and construction works. Our contractors will be required to demonstrate a commitment to providing opportunities for local and Indigenous workers and suppliers throughout project delivery.
Businesses interested in working on this project are encouraged to register their interest through Powerlink’s ICN Gateway, which connects local and Indigenous suppliers with current and upcoming work packages.
