Show Me the Solar: Missouri’s Largest Investor-Owned Project Breaks Ground


Missouri’s largest investor-owned utility solar facilty breaks ground with ceremonial installation of first solar panel. The facility is expected to generate 5.7 MW of electricity, enough to power 650 homes.

In April, construction began on the O’Fallon Renewable Energy Center in O’Fallon, Missouri. This facility represents Missouri’s largest utility solar facility that is 100% investor owned.

At the ground-breaking ceremony, Michael Moehn, the chairman, president, and CEO of Ameren Missouri, stated, “The solar energy center we are starting to build in O’Fallon today represents the kind of cleaner energy resource many of our customers have asked us to build to provide them with energy, and we are proud to be taking this historic step to do just that…. We are working to diversify our mix of generation sources and transition to cleaner and renewable energy sources. Building this solar facility is a critical part of this goal.”

When completed, the facility is expected to use 19,000 solar panels and generate 5.7 MW of electricity, enough to power approximately 650 homes. 

Llona Weiss, Deputy Director for Administration in the Missouri Department of Economic Development’s Division of Energy, said, “Since 2009, Missouri has made great strides in renewable energy production, due in large part to Governor Nixon’s commitment to clean, affordable and abundant energy.”   

The O’Fallon Center is scheduled to be online before the end of the year.
