Thousands of CenterPoint customers in Minnesota were hit with late fees and bank charges because the utility made errors as it processed $47 million in refunds.
The gas and electricity provider appeared before the Public Utilities Commission on Thursday to request approval to refund interest incorrectly charged to customers.
The problems started in mid-November, when CenterPoint processed $47 million in refunds to customers after the utility imposed an interim 5.4 percent rate hike last year, only for the PUC to approve a much smaller final rate.
