Some Xcel Energy customers may have opened their energy bills and discovered someone else's information printed on them.
Xcel Energy said it is notifying approximately 16,000 of its 1.4 million customers in Minnesota and South Dakota that their accounts were printed on another customer's bill.
The bills, dated Nov. 12, included another customer's name, address, account and meter numbers, energy use and the amount owed.
"It does not include any billing or payment history or sensitive personal or financial information, such as Social Security numbers or bank account information," said the company, which is changing the customer account numbers of those affected.
The mix-up was made by its bill printing vendor and no external party had accessed their records, Xcel said.
The company is sending letters notifying customers of the mix up and a corrected statement.
