Ameren Missouri customers will be paying a little more for electricity starting later this month.
The Missouri Public Service Commission has approved an increase in the surcharge customers pay to account for Ameren's fuel and power purchases.
The fuel adjustment clause will rise by 66 cents a month to a total of $3.63 for a residential customer using 1,100 kilowatt-hours of electricity a month. The change will take effect May 27.
That money could add up for Ameren Missouri, because the utility serves about 1.2 million electric customers in the state.
Missouri law allows utilities to bill customers for changes in fuel costs without waiting for their next general rate case.
