A. Notwithstanding any other law, a public power entity may not release customer-specific information without specific prior written customer authorization unless the information is reasonably required for legitimate account collection activities or credit analysis activities or when such information aids in providing safe and reliable service to the customer or unless otherwise provided by court order. A public power entity shall adopt reasonable rules and procedures to ensure confidentiality.

B. Notwithstanding any other law, records and proceedings relating to competitive activity, including trade secrets or privileged or confidential commercial or financial information, if disclosure of the information could give a material advantage to another entity, are not open to public inspection and may not be made public except by order of the public power entity’s governing body. The information protected as confidential under this section is any information that is similar to the information that would be confidential under section 40-204 if reported by a public service corporation to the Arizona corporation commission.
