We own and operate a portfolio of electricity generation assets in Queensland. This includes two of the youngest and most efficient coal-fired power stations in Australia – Stanwell Power Station in Rockhampton and Tarong North Power Station in the South Burnett.

We are proud to generate the energy that powers Queensland lives and businesses.

We believe in affordable, reliable and clean energy and that’s why we are exploring new ways of producing electricity that enhances lives and protects the environment.

On 31 October 2019, ownership of our low and no emission power stations was transferred to CleanCo Queensland. This includes the gas-fired Swanbank E Power Station and the three Far North Queensland hydro facilities (Kareeya, Barron Gorge and Koombooloomba).

Coal

We own 40 per cent of Queensland’s low-cost, coal-fired generating capacity.

Our two major electricity generation assets are the 1460 MW coal-fired Stanwell Power Station located in Central Queensland and the 1843 MW coal-fired Tarong power stations in the South Burnett in Southern Queensland.

Stanwell Power Station

Stanwell Power Station is a highly-automated station and is recognised as one of the most efficient and economic coal-fired power stations in Australia.

The power station is located 22km west of Rockhampton, in Central Queensland.

Coal to fuel Stanwell Power Station comes from Curragh Mine in Central Queensland.

Tarong power stations

The Tarong power stations are one of Queensland’s largest electricity generating sites.

The site comprises five units: four units each capable of producing 350 MW and a single 443 MW advanced cycle coal-fired unit.

The 443 MW unit uses the latest technology, making it one of the most efficient coal units in Australia.

The Tarong power stations receive coal from the nearby Meandu Mine (which we also own) via a conveyor.

Gas

Mica Creek Power Station

Stanwell’s gas-fired Mica Creek Power Station in Mount Isa was previously one of two power stations servicing the North West Minerals Province network. Mica Creek Power Station celebrated 60 years in operation in late 2020. After providing energy to the network for 60 years it was placed into cold storage from 1 January 2021.

Stanwell will continue its involvement in the North West Minerals Province, investigating projects which may have the potential to support the future supply of secure affordable electricity to the region, including projects such as the North West Queensland Hybrid Project with Vast Solar.

Diesel

Mackay Gas Turbine

Stanwell’s Mackay Gas Turbine was a remote controlled, on-demand power generator. The 34MW power generator primarily participated in the frequency control markets of the National Electricity Market (NEM), which means it was occasionally required to generate to support the restoration of balance between power demand and supply.

Stanwell has decommissioned the Mackay Gas Turbine into retirement as at 1 April 2021.

The power generator was originally commissioned in 1975 and was to be retired in 2016/2017 after 40 years of service, but its life was extended five years.

Water

Wivenhoe Small Hydro

Wivenhoe Small Hydro is located below Wivenhoe Dam’s five spillway slots and operates 24 hours a day, seven days a week. The generator captures water released for other primary purposes without commanding dedicated water releases.
