Queensland’s state-owned CS Energy has awarded Monadelphous a $380 million contract to carry out the balance of plant works for the Brigalow Peaking Power Plant near Chinchilla.
The gas-fired peaker will be located next to CS Energy’s Kogan Creek Power Station and provide fast-start capability during periods of high demand to support power system reliability.

Once operational, the 400MW power plant will be capable of reaching full output within five minutes, delivering power to more than 150,000 Queensland homes during peak electricity demand periods.
The Brigalow Peaking Power Plant is part of the Crisafulli Government’s Energy Roadmap, which is investing in coal and gas generation to safeguard domestic energy security and support the energy needs of Queensland.
CS Energy acting CEO Tony Bellas said the appointment marked an important step forward for the project, which CS Energy is developing in a partnership with APA Group.
“Fast start gas peakers like Brigalow will play an important role in Queensland’s future because they can provide longer duration power, complementing shorter duration batteries and intermittent renewables.
“We are delighted to be working with Monadelphous, an experienced contractor in the Australian market with deep capability in energy and mining,” Bellas said.
The balance of plant contract covers the main construction works for the Brigalow Peaking Power Plant, including civil and mechanical works, piping and installation of the gas turbines.
Contractor CMC has completed early enabling works, including site access roads and an intersection upgrade, and will shortly begin the bulk earthworks to prepare the construction pad.

Once the bulk earthworks are completed, Monadelphous will commence the balance of plant works, which is targeted for Q3 2026.
The Brigalow Peaking Power Plant is forecast to be operational by early 2029 subject to final commissioning.
