(a) For purposes of this section, “electrical or gas consumption data” means data about a customer’s electrical or natural gas usage that is made available as part of an advanced metering infrastructure, and includes incremental and monthly meter-specific electricity data, to the extent produced by that infrastructure, and the name, account number, and address of the customer.

(b) (1) An electrical corporation or gas corporation shall not share, disclose, or otherwise make accessible to any third party a customer’s electrical or gas consumption data, except as provided in subdivision (f) or upon the consent of the customer. Customer consent may be verified through an electronic signature authorization process pursuant to the Uniform Electronic Transactions Act (Title 2.5 (commencing with Section 1633.1) of Part 2 of Division 3 of the Civil Code).

(2) An electrical corporation or gas corporation shall not sell a customer’s electrical or gas consumption data or any other personally identifiable information for any purpose.

(3) An electrical corporation or gas corporation or its contractors shall not provide an incentive or discount to the customer for accessing the customer’s electrical or gas consumption data without the prior consent of the customer.

(4) An electrical or gas corporation that utilizes an advanced metering infrastructure that allows a customer to access the customer’s electrical and gas consumption data shall ensure that the customer has an option to access that data without being required to agree to the sharing of the customer’s personally identifiable information, including electrical or gas consumption data, with a third party.

(c) If an electrical corporation or gas corporation contracts with a third party for a service that allows a customer to monitor the customer’s electricity or gas usage, and that third party uses the data for a secondary commercial purpose, the contract between the electrical corporation or gas corporation and the third party shall provide that the third party prominently discloses that secondary commercial purpose to the customer and secures the customer’s consent to the use of the customer’s data for that secondary commercial purpose prior to the use of the data.

(d) An electrical corporation or gas corporation shall use reasonable security procedures and practices to protect a customer’s unencrypted electrical or gas consumption data from unauthorized access, destruction, use, modification, or disclosure.

(e) An electrical corporation or gas corporation shall not share, disclose, or otherwise make accessible to any immigration authority, as defined in § 7284.4 of the Government Code, a customer’s electrical or gas consumption data without a court-ordered subpoena or judicial warrant.

(f) (1) This section does not preclude an electrical corporation or gas corporation from using customer aggregate electrical or gas consumption data for analysis, reporting, or program management if all information has been removed regarding the individual identity of a customer.

(2) This section does not preclude an electrical corporation or gas corporation from disclosing a customer’s electrical or gas consumption data to a third party for system, grid, or operational needs, or the implementation of demand response, energy management, or energy efficiency programs, provided that, for contracts entered into after January 1, 2011, the utility has required by contract that the third party implement and maintain reasonable security procedures and practices appropriate to the nature of the information to protect the personal information from unauthorized access, destruction, use, modification, or disclosure, and prohibits the use of the data for a secondary commercial purpose not related to the primary purpose of the contract without the customer’s prior consent to that use.

(3) Except as provided in subdivision (e), this section does not preclude an electrical corporation or gas corporation from disclosing electrical or gas consumption data as required or permitted under state or federal law or by an order of the commission.

(g) If a customer chooses to disclose the customer’s electrical or gas consumption data to a third party that is unaffiliated with, and has no other business relationship with, the electrical or gas corporation, the electrical or gas corporation is not responsible for the security of that data, or its use or misuse.
