MADISON, Ind. — Duke Energy says a billing glitch resulted in the company overbilling about 7 percent of its residential customers in Indiana, Kentucky and Ohio.
Company spokeswoman Angeline Protogere says it isn't clear how the error was made, but it resulted in the affected customers being overbilled when their bills were estimated.
Protogere says Duke knows exactly which customers were affected and that those customers will be receiving notices letting them know the appropriate amount they should pay this month.
Protogere says the bills that were too high were based on incorrect usage estimates.
She says the company sometimes must estimate a bill because meter-readers can't always access a meter, such as in severe weather like the Midwest's recent heavy snows.
Duke expects to get actual readings on the accounts next month, weather permitting.
