Our coal-fired power stations help underpin power system reliability and we will continue to invest in them to ensure they can operate safely, efficiently and reliably for as long as they are needed. We are also diversifying our portfolio to include renewable energy, firming and storage.
We understand our responsibility to operate in strict accordance with our emissions limits.
Greenhouse emissions
CS Energy reports our greenhouse emissions, energy consumption, and energy production data to the Clean Energy Regulator as part of the National Greenhouse and Energy Reporting Scheme.
CS Energy provides data for the facilities over which we have operational control – Kogan Creek, Callide B and Callide C power stations, and the Chinchilla Battery.
Our greenhouse gas emissions vary each year depending on factors such as the mix of g generation fleet in service, volume of coal consumed and coal quality. In FY2025, CS Energy’s greenhouse gas emissions decreased by 3.3 per cent, in line with the decrease in thermal generation.
Visit the Clean Energy Regulator website for full details of CS Energy's greenhouse emissions.
Other air emissions
CS Energy’s power stations also emit oxides of nitrogen (NOx) and sulphur dioxide (SOx), which are produced as a result of the coal combustion process.
Kogan Creek and Callide C power stations use modern fabric filter bag technology and continuous emissions monitoring systems.
Callide B power station, built in the late 1980s, uses electrostatic precipitator technology for controlling fly ash emissions, which is a commonly used technology around the world today. Callide B continuously monitors its fly ash emissions.
CS Energy conducts regular maintenance of our equipment for controlling emissions to keep it running efficiently.
We report our NOx, SOx and other emissions annually to the National Pollutant Inventory (NPI). Our NPI data is calculated from emissions monitoring equipment at our sites, stack testing results and other operational sources.
A range of factors influence changes in our NPI emissions each year including electricity output, coal quality and maintenance strategy.
