LANSING, Mich. (AP) — A state commission has ordered Jackson-based Consumers Energy to pay a nearly $516,000 fine over billing rules violations.

The Michigan Public Service Commission announced the fine Thursday. It came about five months after the commission began an investigation into the utility’s billing practices in Michigan.

The commission found that Consumers Energy failed to complete meter reads for more than 2,500 customers and determined that the company wasn’t properly communicating how much time customers had to pay bills.

Consumers Energy spokesman Dan Bishop says in a statement that the company hadn’t been meeting its own customer service standards but is “committed to making this right.”

The utility provides electricity and natural gas for more than 6 million residents.
