Members of the Public Service Commission will hear from the public this week as it investigates how AmerenUE responded to the July storms that left hundreds of thousands of households and businesses without electricity, some for more than a week. Ameren officials have said the severity of the storms made it impossible to avoid mass outages and kept crews from quickly restoring service. The PSC says it will investigate how Ameren, as well as other utilties, prepared for the storms and how well it responded. Hearings begin tomorrow in St. Louis. They move to Farmington and Potosi later in the week.
