AmerenUE's Missouri Pure Power program is sourced from wind facilities located in Missouri, with plans to support a more eligible renewable resources sourced from the region in the future.

"AmerenUE has long supported renewable energy with our hydroelectric facilities, and now we are proud to offer Pure Power, something customers can do today to support wind projects in Missouri.
