Overview 

Under the National Electricity Rules, Powerlink is required to maintain system strength in 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 Nebo 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 Nebo Substation. 

The Nebo Synchronous Condenser will be one of four synchronous condensers installed in Central Queensland by 2029. 

The Nebo 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 Nebo community and other local stakeholders throughout April and May 2026.

Get involved 

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.

System Strength Project

System strength is the transmission network’s ability to maintain stable voltage during normal operation and when there is a disturbance, like a sudden change in generation or load, or an unexpected electrical fault. 
Under the National Electricity Rules, Powerlink is required to maintain system strength in Queensland’s transmission network. This will be achieved through the System Strength Project, involving the installation of four synchronous condenser machines in Central Queensland.
