Do you think electricity bills in your area are getting harder to afford?
Ameren Missouri customers owed $49.7 million in unpaid electricity bills in September, up nearly $2 million from August and above the $47.9 million recorded a year earlier. Nearly 195,000 customers are behind on their utility bills.
Why it matters
Rising arrearages put pressure on St. Louis-area households during the summer cooling season, when air conditioning usage typically pushes debt higher. The figures also bear on Ameren Missouri's pending request for a rate increase that would add about $13 per month to the average residential bill if approved.
Ameren Missouri posted $582 million in third-quarter earnings while customer arrearages reached $49.7 million, with more than $107 million in energy assistance distributed through the end of September. The report does not address how the utility's earnings relate to collection outcomes.
