Cal. Civ. Code § PSC 113.0501

PSC 113.0501 Information available to customers.
(1) Each utility shall have available in its offices where payments are received and at area libraries, copies of its rates and rules applicable to the locality. The rates and rules shall be available for customer inspection by electronic, written or telephonic means and reasonable notice as to their availability shall be provided to customers.
(2) Each electric utility, for every municipality in which it serves shall provide in the respective telephone directories a telephone listing by which the utility can be notified during a 24-hour day of any utility service deficiency or emergency which may exist.
(3) Where a second language is common in a particular area served by the utility and so identified by the commission, all rules pertaining to billing and credit shall be available upon customer request, for distribution in English and that second language in every business office of the utility in that area accessible to the public and where customer payments are received.
(4) Each utility shall provide written notice to its residential customers annually and a written notice to all new residential customers, at a minimum, of the rules on deposits, payment options including deferred payment agreements and budget billing, disconnection and dispute procedures; of the availability of information on energy conservation practices, of the availability of a clear, concise record of the customer’s actual electric consumption (or actual degree-day adjusted electric consumption) for each billing period during the prior 12 months or the actual number of months that the customer has lived at that location if less than 12 months and of the availability of agencies or programs which may provide financial aid assistance or counseling; and contain a reply procedure to allow customers an opportunity to advise the utility of any special circumstances, such as the presence of infants or elderly persons or the use of human life-sustaining equipment and to advise the utility to contact a specific third party agency or individual prior to any disconnection action being taken.
(5) A utility shall provide on request to current or prospective customers, tenants or property owners residential energy consumption information. This information shall include either the average consumption for the prior 12-month period or figures reflecting the highest and lowest consumption amounts for the previous 12 months. Provision of this information is neither a breach of customer confidentiality nor a guarantee or contract by the utility as to future consumption levels for the premises in question. The requestor shall be entitled to one such statement at a charge not in excess of $1 once every 12 months. Additional statements shall be furnished if the customer pays the utility’s reasonable costs of preparing and furnishing the statement.
