Ameren Illinois Set the Bar for Voltage Optimization
According to the Opinion Dynamics Report, published March 30, 2026, Ameren Illinois delivered 486 gigawatt-hours (GWh) of energy savings to its customers through its advanced voltage optimization program powered by DVI Grid Solutions’ EDGE® software. The performance exceeded Ameren Illinois’ original goal by 15 percent. 1
DVI Grid Solutions (DVI) delivers a best-in-class software alternative for electric utilities through a real-time, closed loop engineered solution. This advanced approach enables utilities to optimize grid performance with precision and confidence.
Many “solutions” provide data and leave action to the utility; EDGE® goes further. Powered by patented algorithms, EDGE® delivers Closed Loop Precision Control—continuously monitoring, adjusting, and validating performance in real time. The result requires no new hardware and no changes in customer behavior, just a smarter, more efficient grid that delivers measurable reductions in capacity and energy costs, saving utility customers millions of dollars on their electric bills.
Stephen Tyler, Director of DVI Solutions, noted,
“You can’t optimize what you can’t see. EDGE®gives utilities real-time visibility into customer voltages—and the precision to act on it. This tool is actively supporting Ameren Illinois’ Voltage Optimization Team, and we are proud to contribute to their ability to achieve remarkable energy savings.”
These results demonstrate Ameren Illinois’ continued commitment to innovation, grid efficiency, and responsible energy management, delivering meaningful savings while supporting long-term reliability and sustainability goals. If you are still relying on model-based voltage optimization, you are only seeing part of the story. It is time to understand what is happening at the edge.
