As the power system becomes increasingly complex, utilities and grid operators need powerful tools to plan and operate a reliable, efficient and flexible grid.

Ameren Corporation powers the lives of 2.5 million electric and 900,000 natural gas customers across a 64,000-square-mile service territory in Missouri and Illinois. This Saint Louis-based utility is dedicated to providing reliable and affordable energy, a mission it has successfully met for years.

Electric utilities are facing unprecedented grid complexity. Aging infrastructure, increasing distributed energy resources (DERs) and rapidly changing load patterns are making it harder to maintain reliable operations using traditional grid models.
