Accurate and reliable emissions monitoring
Measuring emissions in real time ensures compliance for RWE
RWE has praised the reliability of Endress+Hauser’s PowerCEMS100 cold-dry extractive gas analyser used at its Didcot plant. It was commissioned in early 2024 as a replacement for an older system from another supplier. The continuous emissions monitoring system (CEMS) provides real-time data on key pollutants like nitrogen oxides (NOx), sulphur dioxide (SO₂), carbon monoxide (CO) and carbon dioxide (CO₂), and ensures compliance with environmental regulations.

The PowerCEMS100 system from Endress+Hauser
The benefits
-
Accuracy and reliability, ensuring the power station can generate electricity whenever demand arises.
-
Enables full compliance with Environment Agency regulations by verifying that measured emissions accurately reflect actual output.
-
Secure access to the CEMS network for remote diagnostics and monitoring.
-
Responsive technical assistance from the Endress+Hauser team.
“The support’s been great from day one.”
RWE
The challenge
RWE’s Didcot B is an efficient combined cycle gas power plant in Oxfordshire powered by natural gas. As for all power plants, reducing emissions via efficient processes and cleaner technologies is of central importance to RWE due to mounting competitive pressure and growing requirements regarding environmental and climate protection. To demonstrate adherence to emissions limits set by the Environment Agency, RWE relies on a continuous emissions monitoring system (CEMS) from Endress+Hauser.
The solution
Thanks to a strategic partnership with the German sensor technology specialist SICK, Endress+Hauser now exclusively markets SICK’s gas analysis and flow measurement technology worldwide. This includes the PowerCEMS100 cold-dry extractive gas analyser used at the Didcot plant. As Control and Instrumentation Maintenance Engineer Ewen Kindness explains, reliability is key: “It’s critical to record the environmental data – without this, we would not be compliant and could risk power generation.”
