Consumers Council is actively involved in rate cases filed by Missouri American Water Company, which is proposing a +40% increase in residential water rates, and Ameren Missouri, which is seeking a +15.77% rate hike. Public hearings for the water rate increase have already been completed, while the public hearings for Ameren’s proposed rate increase will take place from January 21-27, 2026. According to the Missouri Public Service Commission, the average residential customer of Ameren Missouri could see an increase of approximately $17.45 per month.

Spire has filed a notice signaling that they too may request a rate increaseby November 19, 2024. In September 2024, the St. Louis Post-Dispatch reported allegations from a former Spire official that the utility instructed staff to conceal documents potentially blocking larger rate hikes. This claim is currently under investigation.

The Missouri Public Service Commission will hold local public hearings starting on October 28, 2024, to receive customer comment in the + 34% rate increase case filed by Missouri-American Water Company (MAWC). There will be in-person and virtual local public hearings conducted by the Public Service Commission.

Following on the heels of Ameren, on July 2, 2024, Missouri American Water Company (“MAWC”) requested a general rate increase of approximately +$166.6 million or +34.4% annually for water and sewer services. Consumers Council is continuing to review MAWC’s rate request and has intervened in this case.
