Callide B Coal Power Plant | Queensland, Australia

Callide B is a coal-fired power station located in Queensland, Australia, with a capacity of 700 MW. Operated by CS Energy, it is a significant contributor to the state's baseload power generation. The plant is part of the Callide Power Station complex, which includes both Callide A and Callide B units. The facility uses coal as its primary fuel and operates under Australia's national environmental regulations, including the National Greenhouse and Energy Reporting Act and state-level emissions standards. Coal plants of this scale typically employ subcritical or supercritical steam cycles. The plant's age and technology influence its efficiency and emissions profile. Callide B serves the National Electricity Market (NEM), supplying power to residential, commercial, and industrial customers in Queensland. Its operational status as an active coal plant places it within the context of Australia's energy transition, where coal generation is increasingly balanced with renewable sources. The plant's location in a rural area reduces direct population exposure to emissions, but its carbon footprint remains a consideration in the broader environmental context.

The plant's coal fuel source results in significant CO2, SOx, and NOx emissions, typical for coal-fired generation. Its location in a rural area of Queensland reduces immediate population exposure, but the emissions contribute to regional air quality and greenhouse gas levels. The facility's age and technology (likely subcritical) may result in lower efficiency compared to modern supercritical plants, increasing its per-MWh environmental impact. Regulatory frameworks such as the National Pollution Inventory require reporting of emissions, but specific control technologies are not detailed.
