New continuous emissions monitoring system (CEMS) technology has been installed at two CS Energy power stations to provide the company with more accurate and reliable information about its emissions.
The improved CEMS technology has been progressively fitted to Kogan Creek and Callide C power stations over the past 18 months and will be used for reporting its emissions to various state and federal bodies.
CS Energy’s head of environment Brendan Monckton said the new technology replaced previous CEMS at the two power stations.
“CEMS technology has improved significantly since Callide C and Kogan Creek were commissioned,” Mr Monckton said.
“The new CEMS technology that we are using has improved our real-time emissions monitoring and provides more accurate emissions data.”
Under CS Energy’s environmental licence, CS Energy monitors and reports on emissions such as nitrogen oxides and particulates.

“The new CEMS is also monitoring for additional parameters such as oxygen and carbon dioxide, which enables us to better monitor boiler conditions and make adjustments to improve the units’ efficiency,” Mr Monckton said.
“Ensuring we operate our sites within their environmental licence is a high priority for CS Energy and we are always looking for improvements in technology that can help us deliver outcomes like this.”
Emissions management at CS Energy
Callide C and Kogan Creek are two of the newest and most efficient coal-fired power stations in the National Electricity Market and feature:
- modern fabric filter bag technology to capture 99.9 per cent of the fly ash produced before it is released into the air
- supercritical boiler technology, which means they operate at a higher efficiency and have lower greenhouse emissions compared to most coal-fired power stations in Australia.

All of CS Energy’s power stations use low sulfur coal, which means sulfur dioxide emissions are low compared to world standards.
CS Energy conducts regular maintenance of its equipment for controlling emissions and reports its nitrous oxide (NOx), particulate emissions and sulfur dioxide (SO2) emissions annually to the National Pollutant Inventory.
CS Energy’s coal-fired power stations also produce greenhouse emissions as a by-product of the coal combustion process used to generate electricity.
Australia’s changing generation mix
CS Energy says its coal-fired power stations will play an important role for many years to come in providing reliable electricity as the economy transitions to a greater use of renewable energy.
In FY2019, the company’s power stations sent out more than 10 per cent of the electricity generated in the National Electricity Market (NEM).
CS Energy’s strategy is built around maximising the life and value of its existing assets, while also diversifying its business to include new sources of energy as the energy industry transitions to a lower carbon future. This includes investing in renewable energy through offtake agreements and partnering with QUT and its collaborators on a green hydrogen project.
