Sincerely, Edward F. Randolph, Director Energy Division

Megan Scott-Kakures Vice President, Regulatory Operations July 9, 2014 ADVICE 3072-E (U 338-E) PUBLIC UTILITIES COMMISSION OF THE STATE OF CALIFORNIA ENERGY DIVISION SUBJECT: Establishment of the Mobilehome Park Master Meter Balancing Account in Compliance With Decision 14-03-021 In compliance with the California Public Utilities Commission s (Commission s or CPUC s) Decision (D.)14-03-021 (or the Decision), effective March 13, 2014, Southern California Edison Company (SCE) hereby submits for filing the following changes to its tariffs. The revised tariff sheets are listed on Attachment A and are attached hereto. PURPOSE Pursuant to D.14-03-021 Ordering Paragraph (OP) 8, this advice filing establishes Preliminary Statement Part MM, Mobilehome Park Master Meter Balancing Account (MMMBA), to record costs associated with the conversion of master-metered service to direct service. In addition, Preliminary Statement Part YY, Base Revenue Requirement Balancing Account (BRRBA) is modified to account for the MMMBA. BACKGROUND On March 13, 2014, the Commission issued D.14-03-021 which adopted a three-year living pilot program to incentivize voluntary conversions of master-metered service to direct service at mobilehome parks (MHP). The program directs SCE to convert approximately 10 percent of the spaces within its service territory over the pilot program s three-year term. The Decision authorizes the creation of a balancing account for recording actual MHP program costs. The Decision directed that each utility submit an advice letter on or before July 30, 2014, for approval of a new tariff to establish the voluntary, mobilehome park/manufactured housing community conversion program that contains all the program components referenced and described in the Decision. In this advice letter, SCE requests approval to establish a balancing account for recording actual MHP P.O. Box 800 8631 Rush Street Rosemead, California 91770 (626) 302-6855 Fax (626) 302-4829

ADVICE 3072-E (U 338-E) - 2 - July 9, 2014 conversion program costs. On or before July 30, 2014, SCE will submit a new tariff, program application, and program agreement detailing the terms and conditions of the MHP conversion program. Specifically, D.14-03-021 requires that reasonable incremental expenses for program development and administration, not otherwise recovered in rates, should be entered as incurred for annual recovery in SCE s pilot program balancing account. 1 PROPOSED TARIFF CHANGES As discussed above, and in accordance with OP 8 of D.14-03-021, SCE requests to establish Preliminary Statement Part MM, MMMBA, to record the incremental costs associated with the conversion of the master-metered service. Incremental costs include the incremental revenue requirement associated with to the meter costs capitalized and placed in service upon system cutover to direct utility service, including incremental Operation and Maintenance start-up costs such as customer outreach, administrative and other ongoing costs to implement the three-year pilot program. The MMMBA will also record the incremental revenue requirement for the regulatory asset associated with beyond the meter costs incurred. The regulatory asset will be amortized over a ten-year period earning a rate of return at SCE s currently authorized rate of return. Additionally, Preliminary Statement Part YY, BRRBA, is modified to include a debit entry to the Distribution Sub-account to record the transfer from the MMMBA. No cost information is required for this advice filing. This advice filing will not increase any rate or charge, cause the withdrawal of service, or conflict with any other schedule or rule. TIER DESIGNATION In accordance with OP 9 of D.14-03-021, this advice letter is submitted with a Tier 2 designation. EFFECTIVE DATE SCE respectfully requests that this filing become effective on August 8, 2014, the 30 th calendar day after the date filed. 1 D.14-03-021, p 3.

Actual construction costs for each MHP conversion shall be entered into a balancing account and recovered in the year immediately following service cut over for that MHP. 2. Operation of MMMBA Entries to the MMMBA shall be made monthly, and shall be determined as follows: a. A debit entry equal to the recorded incremental (O&M) expenses, including applicable payroll taxes and benefits on SCE labor; b A debit entry equal to the incremental capital-related revenue requirement, excluding associated Franchise Fees and Uncollectibles (FF&U) expenses related to the to the meter capital costs incurred. The capital-related revenue requirement shall include depreciation expense, return on rate base at thecurrently authorized rate of return on rate base and applicable taxes, such as income and ad valorem taxes; c.
