Pub. Util. Code, § 367.7

(a) It is the intent of the Legislature in enacting this section to ensure that individual customers do not experience rate increases as a result of the allocation of transition costs, in accordance with paragraph (2) of subdivision (e) of Section 367.

(b) The commission shall implement a methodology whereby the Power Exchange energy credit for a customer with a meter installed on or after June 30, 2000, that is capable of recording hourly data is calculated based on the actual hourly data for that customer. The Power Exchange energy credit for a customer with a meter installed before June 30, 2000, that is capable of recording hourly data shall, at the election of the customer, on a one-time basis before June 30, 2000, be calculated based on either (1) the actual hourly data for that customer or (2) the average load profile for that customer class. If the customer fails to make an election, that customer’s Power Exchange energy credit shall continue to be based on the average load profile for that customer class.

(c) Additional incremental billing costs incurred as a result of the methodology implemented by the commission pursuant to subdivision (b) may be recoverable through rates for that customer class, if the commission finds that the costs are reasonable.

(d) The methodology implemented by the commission pursuant to subdivisions (b) and (c) shall not result in any shifts in cost between customer classes and shall be consistent with the firewall provision set forth in subdivision (e) of Section 367.
