Tarong (Oil) Diesel Power Plant, Queensland, Australia

Tarong (Oil) is a diesel-fired power plant located near the Tarong region in Queensland, Australia. With a capacity of 15 MW, it is a small-scale facility that serves as a peaking plant, providing electricity during periods of high demand. The plant is owned and operated by Tarong Energy Corporation and is part of Australia's National Electricity Market (NEM). Diesel power plants like Tarong (Oil) are typically used for emergency backup or peak load support due to their fast start-up capabilities. In Australia, such plants are subject to national emissions regulations under the National Greenhouse and Energy Reporting (NGER) scheme and state-level environmental protection laws. The plant's relatively small capacity and oil fuel source mean it has a higher carbon intensity compared to natural gas or renewable alternatives. Operationally, Tarong (Oil) plays a role in grid stability and reliability, particularly in the Queensland region. While its environmental footprint is notable due to diesel combustion, its limited operating hours as a peaking plant reduce overall emissions. The facility contributes to energy security by providing rapid response to demand spikes or generation shortfalls.

The Tarong (Oil) plant uses diesel fuel, which has higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewables. Its location in Queensland, a region with significant coal and gas generation, means it operates in a mixed energy landscape. The plant's small capacity and peaking role limit its continuous environmental impact, but local air quality may be affected during operation. Typical diesel plants are sited with consideration for emissions dispersion.
