Case Study: Arkansas Electric Cooperative Corporation achieves lower emissions compliance costs with Rockwell Automation Software CEM

Arkansas Electric Cooperative Corporation - Customer Case Study

Arkansas Electric Cooperative Corporation (AECC) needed to replace obsolete emissions analyzers on seven gas turbines while meeting strict environmental regulations and reducing the high capital and maintenance costs of a hardware-based continuous emissions monitoring system (CEMS). To solve this, AECC evaluated options and selected Software CEM® from Rockwell Automation to improve compliance, accuracy, flexibility, and long-term operating costs.

Rockwell Automation implemented a software-based, model-driven Predictive Emissions Monitoring System that uses existing process sensor data and real-time sensor validation to predict emissions without hardware analyzers. The solution helped AECC save more than $50,000 per year, with a projected $500,000 in 10-year ownership savings and a one-year ROI versus hardware replacement. It also achieved better than 7.5% initial RATA accuracy, outperforming the EPA’s +/-10% requirement, while increasing uptime and reducing compliance risk.
