Mount Stuart Power Station414 MW Oil

OilVerified: Feb 2026

Mount Stuart Power Station is a critical energy generation facility located in Australia, specifically at the coordinates of -19.3377, 146.8511. As an oil-fired power plant, it plays a significant role in the national energy mix, providing a substantial 414 MW capacity to the grid. Commissioned in 1998, this facility has been instrumental in meeting the energy demands of the region, particularly in times of peak load when renewable energy sources may not suffice. Operated by Origin Energy, a leading player in the Australian energy market, Mount Stuart utilizes advanced oil combustion technology, which allows for flexible and reliable power generation. The location of the plant in Queensland is strategic, as it enhances the stability and reliability of the local power grid, catering to both residential and industrial consumers. Australia's energy policy has increasingly focused on transitioning to renewable sources; however, oil remains a crucial component for backup generation and energy security. This importance is underscored by the plant's operational context, where it supports the integration of intermittent renewable resources such as wind and solar. As such, Mount Stuart Power Station not only contributes to the immediate energy needs but also aligns with broader energy policies aimed at ensuring a stable and reliable power supply in Australia.
