Smart Emissions Monitoring for a Thermal Power Plant
AI-powered NOx estimation delivered compliant monitoring and ESG-grade reporting without new hardware expansion.
ITChamps deployed an AI-powered soft sensor for NOx estimation, replacing the assumption that compliant emissions monitoring requires new hardware CEMS investment.
The Challenge
Compliance-grade emissions monitoring had to be both accurate and economical
NOx output shifted with combustion dynamics, fuel quality, and load, while traditional hardware CEMS options imposed high procurement and maintenance costs.
- NOx levels changed continuously with plant operating conditions.
- Fuel quality variability disrupted stable emissions relationships.
- Traditional hardware CEMS met compliance needs but at high cost.
- Any software-led method needed to satisfy regulatory scrutiny.
The Solution
A 25-parameter soft telemetry model on top of existing plant data
ITChamps mapped plant parameters, built an AI estimation model, deployed live NOx prediction, and created a continuous reporting stream for regulatory and ESG use.
Identified the plant variables with the strongest predictive weight for NOx output.
Built a 25-parameter estimation model to reflect true combustion variability.
Validated the approach for compliant monitoring and ongoing reporting.
Results
Measured business impact
The soft telemetry engine used 25 real-time operating inputs.
The monitoring method achieved regulatory-grade acceptance.
No new CEMS expansion was required for rollout.
Total operating cost was lower than the hardware-led alternative.
Highlights
- The client gained real-time operator insight into emissions behavior.
- Compliance and ESG reporting were supported from the same platform.
- The approach reduced the need for hardware-heavy monitoring expansion.
- The framework can be replicated across additional units.
