Our foundation assets include the Wivenhoe pumped storage hydro power station, Swanbank E gas power station, and three Far North Queensland hydro stations, including Barron Gorge, Kareeya and Koombooloomba.
We commenced trading on 31 October 2019, when the ownership of these assets was transferred from CS Energy and
Stanwell to CleanCo.
Combined, our portfolio of assets has the capacity to generate 1,120 MW.
Barron Gorge Hydro Power Station
Located 20 kilometres north west of Cairns in Far North Queensland, Barron Gorge Hydro sources water from the Barron
River to produce electricity before releasing the water back into the river.
Comprising two 33 MW generators, Barron Gorge Hydro can start up quickly, providing a secure, reliable energy supply for
distribution to consumers.
Kareeya Hydro Power Station
Located in the Tully River catchment area in Far North Queensland, Kareeya Hydro has been generating electricity for
Queenslanders for over 60 years.
Water flowing down the Tully River is captured at the Tully Falls Weir and then transported underground to the 88 MW Kareeya Hydro. The station’s ability to start up quickly makes it an important asset in providing a secure, reliable energy supply for distribution to customers.
Koombooloomba Hydro Power Station
Located in the Tully River catchment area in Far North Queensland, the 7 MW Koombooloomba Hydro generates electricity from water released from Koombooloomba Dam. The electricity generated is then transported to the Kareeya Hydro before being fed into the Queensland electricity grid.
Swanbank E Power Station
Located near Ipswich in South East Queensland, Swanbank E Power Station is a 385 MW gas-fired power station, featuring the Alstom GT26 gas turbine. The power station uses fuel gas from multiple sources via the Roma to Brisbane Pipeline.
Using highly efficient combined cycle technology, waste heat from the gas turbine is used to generate additional electricity via a second turbine at no extra fuel cost.
Wivenhoe Pumped Storage Hydro Power Station
Located approximately 50 km west of Brisbane in South East Queensland, Wivenhoe Power Station is the only pumped storage hydroelectric plant in Queensland and can ramp quickly to support a stable electricity supply.
With two 285 MW generators – the largest hydro machines in Australia – Wivenhoe operates like a giant rechargeable battery, with water cycled between Splityard Creek Dam (upper reservoir) and Wivenhoe Dam (lower reservoir).
Electricity is generated through the following steps:
- Water is pumped from Wivenhoe Dam uphill to Splityard Creek Dam and stored there until it is needed.
- To generate electricity, water is pumped from Splityard Creek Dam downhill through tunnels to flow through the
- The rotation of the turbine spins a powerful electromagnet, which creates electricity.
- Electricity is then increased in volts through a transformer and transported from the power station via transmission
- Water is pumped back to Wivenhoe Dam, ready to be used again.
