A public utility commonly possesses confidential information regarding its customers. This information including, credit card numbers, Social Security numbers, account numbers, security codes, and other identifying information in the hands of a utility must be redacted prior to the release of any public record. Furthermore, 2012 legislation made consumer-specific energy use data confidential, but left aggregate monthly billing information open to public inspection. Thus, a customer’s monthly usage is open but a breakdown by date and time is not.
When a customer provides the utility with a copy of a valid protection order and requests confidentiality, identifying information, such as unlisted telephone numbers, in the possession of a private or public utility service provider that could be used to locate an individual cannot be released.
Records of a utility that would identify areas of vulnerability or allow disruption of utility service are likewise confidential.
