O'Fallon Renewable Energy Center

With more than 19,000 solar panels, our O'Fallon Renewable Energy Center is the largest investor-owned universal solar facility in Missouri.   

  • Our multi-crystalline solar panels span an area approximately the size of 19 football fields, allowing us to collect nearly 8 million kilowatt-hours of energy from the sun’s rays every year.
  • The facility began delivering carbon-free energy to our customers in December 2014, with a generation capacity of 5.7 megawatts.
  • We've continued to invest in our premiere solar field by installing smart technology that allows us to operate and monitor the renewable energy center remotely, so we can find and fix problems fast.  
The O’Fallon Renewable Energy Center is just one way we’re focused on securing Missouri’s energy future. See how we're harnessing the power of the sun.

Solar Partnership – BJC HealthCare

Ameren Missouri partnered with BJC HealthCare to put 4,500 solar panels on top of a parking garage on its medical campus with a generation capacity of approximately 1.8 MW. The solar installation covers the area of two football fields, and is now serving all customers with clean energy. Projects like this solar partnership create benefits for both our customers at large and our project partners. All Ameren Missouri customers win when more renewable energy is added to the grid, offsetting other forms of generation. Our solar project partners – in this case, BJC HealthCare – win by turning their unused space into a shaded parking garage for employees that generates clean energy.
