SUBJECT:

Supplement to Advice 3853-E, Establishment of Time-of-Use
Rates for Commercial Electric Vehicle Charging and
Modification to the Rule 1 Definition of Electric Vehicle in
Compliance with Decision 18-05-040

PURPOSE
Southern California Edison Company (SCE) hereby submits the following supplement to
Advice 3853-E. This supplement is made at the request of the California Public Utilities
Commission’s (Commission or CPUC) Energy Division. SCE intends to seek approval
from the Federal Energy Regulatory Commission (FERC) via a Single-Issue Section
205 Filing (Filing) for the proposed transmission retail rate cost recovery method related
to the following proposed time-of-use (TOU) rates for commercial electric vehicle
charging (collectively, the New EV Rates):
•
•
•

Schedule TOU-EV-7, General Service Time-of-Use, Electric Vehicle Charging,
with Option E (Energy Only) and Option D (Demand Metered);
Schedule TOU-EV-8, General Service Time-of-Use, Electric Vehicle Charging,
Demand Metered; and
Schedule TOU-EV-9, General Service Time-of-Use, Electric Vehicle Charging,
Large Demand Metered.

SCE’s proposed changes are made in accordance with General Order (GO) 96-B,
General Rule 7.5.1, which authorizes utilities to make additional changes to an advice
letter through the submittal of a supplemental advice letter. This advice letter partially

ADVICE 3853-E-A (U 338-E) -2- October 4, 2018 BACKGROUND Pursuant to Decision (D.)18-05-040, Ordering Paragraph (OP) 45, SCE submitted Advice 3853-E on August 29, 2018, with proposed revisions to the definition of Electric Vehicle (EV) in SCE’s Rule 1, Definitions, to be consistent with the statutory definition of transportation electrification codified in Public Utilities Code Section 237.5. In compliance with the same order, SCE also proposed to establish the New EV Rates that were developed consistent with the method agreed upon by parties in the Joint Stipulation set forth in Exhibit Joint -12 of SCE’s Application (A.)17-01-021.1 On August 31, 2018, Energy Division issued a notice suspending Advice 3853-E because it requires staff review. On September 20, 2018, Energy Division requested that SCE supplement Advice 3853E outlining SCE’s plan to request the FERC’s approval of the transmission retail rate cost recovery method related to the New EV Rates with a description of the full 10-year rate transition SCE proposed in A.17-01-021 as modified by the Joint Stipulation and conditionally approved by the Commission in D.18-05-040. Furthermore, Energy Division stated that the supplement should include information about the General Rate Case (GRC) processes and how and when FERC Filings may be necessary to implement the New EV Rates. DISCUSSION As stated in Advice 3853-E, the fundamental design of SCE’s New EV Rates is consistent with the methodology agreed upon by parties in the Joint Stipulation,2 including the 70/30 proxy allocation method for recovering transmission retail rate costs, which the Commission conditionally approved on a temporary 3-year basis provided that SCE seeks approval from FERC for the initial 5-year energy only rate structure, and for the overall 10-year transition plan to include the ultimate 70/30 split of transmission retail rate cost recovery structure. Accordingly, in order for SCE to implement the New EV Rates by the first quarter of 2019, SCE will submit its initial FERC Filing by mid to late November 2018,3 requesting approval of the method for recovering transmission 1 2 3 A.17-01-021, Exhibit No. Joint-12, Southern California Edison Company, Office of Ratepayer Advocates, Natural Resources Defense Council, Environmental Defense Fund, Siemens, Sierra Club, and the Coalition of California Utility Employees Stipulation. See D.18-05-040 at p. 114. See also OP 43 at p. 161. SCE is required to make a single-issue Section 205 filing to revise its retail transmission rates pursuant to Section 8d of the Protocols of the Formula Rate set forth in Appendix IX of SCE’s Transmission Owner Tariff, FERC Electric Tariff, Third Revised Volume No. 6, that states: “SCE will make a single-issue Section 205 filing to revise Schedule 33 of the Formula Rate determination of retail transmission rates to reflect any change in Rate Groups, Rate Schedules, or the design of retail rates applicable to each Rate Schedule subsequent to any final CPUC order that affects these aspects of retail transmission rates. SCE will make such a filing only if and when the change in Rate Groups, Rate Schedules,

ADVICE 3853-E-A (U 338-E) -3- October 4, 2018 retail rate costs associated with the New EV Rates. In the initial FERC Filing, SCE will provide a summary of the Joint Stipulation adopted by the Commission that allows SCE to implement the New EV Rates in a 10-year phased approach. During the introductory phase (years 1-5), the transmission costs associated with the New EV Rates will be recovered through volumetric ($/kWh) energy charges and then, beginning year 6, the recovery of the transmission costs will be bifurcated between non-coincident demand and energy charges, which will be increased incrementally by the percentages of noncoincident demand revenues recovery until it reaches 70 percent in year 10. SCE anticipates the FERC’s approval of the initial FERC Filing in early 2019. In year 5, SCE plans to submit a FERC Filing to reflect the introduction of non-coincident demand charges that will take effect in the subsequent years. In addition to the FERC Filing and in compliance with the Commission’s order, SCE will complete a transmission marginal cost study and include the result and proposal in its 2021 GRC Phase 2 application. SCE expects to begin the study in the third quarter of 2019, in time for the expected filing of the 2021 GRC Phase 2 application in the second quarter of 2020. The New EV Rates will be updated, as needed, based on the result of SCE’s 2021 GRC Phase 2 application. No cost information is required for this advice letter. This advice letter will not increase any rate or charge, cause the withdrawal of service or conflict with any other schedule or rule. TIER DESIGNATION Pursuant to General Order (GO) 96-B, Energy Industry Rule 5.2, this advice letter is submitted with a Tier 2 designation, which is the same Tier designation as the original Advice 3853-E. EFFECTIVE DATE In accordance with GO 96-B, General Rule 7.3.2, SCE requests that this advice letter become effective concurrent with SCE’s proposed effective date for its 2018 GRC Phase 2 rate changes, expected to be in the first quarter of 2019. or the design of retail rates cannot otherwise be reflected through the normal operation of the Formula Rate. In the single-issue Section 205 filing to the Commission, SCE will propose revisions to Schedule 33 of the Formula Rate that conform to the CPUC order. SCE will make a filing under this Section 8(d) by the later of either the filing date for the next Annual Update following the CPUC ruling or sixty days after the CPUC ruling” (emphasis added). The Annual Update pursuant to Section 8d of the Protocols of the Formula Rate is scheduled on or before December 1 of each year.
