Public hearings have been scheduled around the state in February and March about Ameren Missouri's request for a rate increase.
St. Louis-based Ameren Missouri filed a request late last year for an 11 percent increase to electric rates in all rate classes, amounting to $263 million annually.
The Missouri Public Service Commission begins evidentiary hearings on the request in April. The commission is sponsoring the public hearings to give customers a chance to ask questions about the possible increase.
If the commission grants the rate increase, Ameren estimates the average residential customer will pay an additional $9.30 a month, based on 1,100 kilowatt-hours.
