fuel surcharge

Ameren Missouri customers can expect to see a slightly lower bill after state regulators determined the utility owes its electric customers slightly more than $26 million for failing to include some revenue in its calculations.

The Missouri Public Service Commission approved an order Wednesday for the St. Louis-based company to refund the money to customers. But Ameren Missouri won't be sending out checks. Instead, the $26.3 million will be applied by adjusting a fuel charge that customers otherwise would pay.
