DENVER -- Xcel Energy is warning residents to be on the lookout for men posing as its employees.
According to the company, there were more than a dozen reports last week of two men claiming to work for Xcel.
They reportedly ask residents if they can enter their home to check voltage.
Both men are described as wearing light gray shirts and dark gray pants.
Xcel says all employees are required to carry company ID cards and customers should always ask to see it if someone claims to be with the company.
