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’s greenhouse gas emissions vary each year depending on factors such as the mix of generation fleet in service, volume of coal consumed and coal quality.

In FY2024, CS Energy’s electricity production increased by 8.2 per cent, resulting in a 5.4 per cent increase in our scope 1 emissions compared to FY2023.

More than half of our electricity generation in FY2024 was from the supercritical Kogan Creek Power Station, which has one of the lowest greenhouse gas intensities for a coal-fired power station in the National Electricity Market. As a result, our portfolio greenhouse gas intensity decreased by 2.5 per cent in the same period.

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.
