Collinsville, IL— November 6, 2025 — The Association of Edison Illuminating Companies (AEIC), the electric utility industry’s leading authority for operational excellence, announced today that Ameren Illinois has received one of the Association’s 2025 Achievement Awards.

The AEIC Achievement Awards are presented annually to member companies who have clearly demonstrated significant contributions to advancing operational excellence in the electric utility industry.

Ameren Illinois was recognized for implementing a solution using robotic process automation (RPA) and Optical Character Recognition (OCR) to reduce inefficiencies for processing and paying vendor invoices. The Ameren Illinois Fleet Services team partnered with the Ameren Center for Automation to develop a bot—affectionately named DW—that automatically extracts key data from the invoices and stores it in a shared file. Employees then review a validation screen to ensure accuracy, maintaining strong internal controls and accounting standards.
