Cal. PUC § 761.5

(a) Where the commission determines that it would be cost-effective, the commission shall authorize electrical and gas corporations to participate in a centralized credit check system to share information on customers; and the electrical and gas corporations may also share information on customers with telephone corporations and publicly owned public utilities. No public utility which participates in the centralized credit check system shall utilize any information obtained through the database for its internal marketing purposes. A public utility may release pertinent information to a collection agency for the purpose of collecting an outstanding bill, but shall not otherwise release, transfer, or sell any information obtained through the centralized credit check system.

(b) Every electrical and gas corporation which participates in a centralized credit check system is subject to the Consumer Credit Reporting Agencies Act (Title 1.6 (commencing with Section 1785.1) of Part 4 of Division 3 of the Civil Code) and the federal Fair Credit Reporting Act (15 U.S.C. Sec. 1681 et seq.).
