On August 1, electric rates for Ameren Missouri customers decreased by 6%. This will save the average residential customer about $72 a year. When federal taxes went down, Ameren Missouri passed those tax savings on to its customers.
Base electric rates for Ameren Missouri customers will not go up from now until April 2020 because the Ameren Missouri Smart Energy Plan includes a rate freeze.
For the first time ever, rate caps will limit the size of any future rate increases for the life of the plan, making your energy costs more stable and predictable.
