ADVICE 4022-E (U 338-E)

PUBLIC UTILITIES COMMISSION OF THE STATE OF CALIFORNIA ENERGY DIVISION

SUBJECT: Establishment of the Wildfire Mitigation Plan Memorandum Account Pursuant to Senate Bill 901 and Decision 19-05-038

Southern California Edison Company (SCE) hereby submits for approval by the California Public Utilities Commission (Commission) the following changes to its tariffs. The revised tariffs are listed on Attachment A.

PURPOSE

In compliance with Commission Decision (D.)19-05-038 (Decision) Ordering Paragraph (OP) 18 and Public Utilities (P.U.) Code Section 8386(e), this advice letter establishes Preliminary Statement Part N.27, the Wildfire Mitigation Plan Memorandum Account (WMPMA). The purpose of the WMPMA is to track costs incurred to implement SCE’s Wildfire Mitigation Plan (WMP) that are not currently reflected in revenue requirements being paid by customers in rates (e.g., in Commission-approved General Rate Case (GRC) base rates revenue requirements), and that are also not being tracked in an another existing Commission-authorized memorandum account (e.g., in SCE’s Fire Hazard Prevention Memorandum Account (FHPMA)).

Upon establishment of the WMPMA, the costs of approved WMP-related activities previously tracked in the Fire Risk Mitigation Memorandum Account (FRMMA)1 will be transferred to the WMPMA. The FRMMA, which will no longer include any costs related to the approved WMP, will remain open to track the costs of wildfire mitigation activities—if any—that are not included in the approved annual WMP or otherwise authorized or tracked in another ratemaking account.

BACKGROUND

On September 21, 2018, former Governor Brown signed Senate Bill (SB) 901, which set in motion wide-ranging activities to strengthen California’s ability to prevent and recover

1 Established in Advice 3936-E-A.

ADVICE 4022-E (U 338-E) - 2 - June 19, 2019

from catastrophic wildfires. In addition to measures directed at other entities, SB 901 requires electric utilities to prepare and submit WMPs that describe the utilities’ plans to prevent, combat, and respond to wildfires. The Commission opened Rulemaking (R.)18-10-007 (SB 901 OIR) on October 25, 2018 to implement this provision of SB 901.

On January 18, 2019 and March 12, 2019, SCE submitted Advice 3936-E and Advice 3936-E-A, respectively, proposing the establishment of the Fire Risk Mitigation Memorandum Account (FRMMA), in compliance with P.U. Code 8386(j). As described in Advice 3936-E:

SB 901 authorizes SCE to establish two separate memorandum accounts to track incremental costs SCE incurs to mitigate wildfire risk. One memorandum account, which SCE proposes to establish in this advice letter, is intended to “track costs incurred for fire risk mitigation that are not otherwise covered in the electrical corporation’s revenue requirement.”2 The second memorandum account, which is to be established upon approval of SCE’s 2019 WMP, is intended to “track costs incurred to implement the plan.”3

The Commission approved Advice 3936-E-A on March 12, 2019, and approved an effective date for the FRMMA of January 18, 2019.

On June 4, 2019, the Commission issued D.19-05-038, approving SCE’s 2019 WMP. This Decision also authorized SCE to “open the memorandum account described in P.U. Code Section 8386(e), which provides: “At the time it approves each [WMP], the [C]ommission shall authorize the utility to establish a memorandum account to track costs incurred to implement the plan.”4 In authorizing this 8386(e) memorandum account, the Commission specified that SCE could not “seek or obtain double recovery of the costs tracked in its P.U. Code 8386(e) memorandum account in any other account, including the [FRMMA].”5

Pursuant to OPs 18 and 19 of the Decision, SCE is establishing the WMPMA to track costs incurred to implement SCE’s approved WMP that are: (1) not currently reflected in other Commission revenue requirements being paid by customers in rates (e.g., in Commission-approved GRC base rates revenue requirements); (2) not pending approval by the Commission via a separate SCE proposal (e.g., in SCE’s pending Grid Safety and Resiliency Program (GSRP) Application (A.)18-09-002); and (3) not being tracked in an existing Commission-authorized memorandum account (e.g., in SCE’s Fire Hazard Prevention Memorandum Account (FHPMA), or Catastrophic Event Memorandum Account (CEMA)). As described in Advice 3936-E, upon approval of this Advice Letter, SCE will transfer the balance in the FRMMA associated with approved WMP-related activities to the WMPMA, and will track the going-forward costs of the approved activities in the WMPMA. The costs in the WMPMA will then be presented to 2 P.U. Code Section 8386(j). 3 P.U. Code Section 8386(e). 4 D.19-05-038, Ordering Paragraph 18. 5 D.19-05-038, Ordering Paragraph 19.

ADVICE 4022-E (U 338-E) - 3 - June 19, 2019

the Commission for review of reasonableness and recovery in a future General Rate Case application (including in SCE’s upcoming 2021 GRC application to be filed in the fall of 2019), consistent with P.U. Code Section 8386(g).

The FRMMA, which will no longer include any costs related to the approved WMP, will remain open to track the costs of wildfire mitigation activities—if any—that are not included in the approved annual WMP or otherwise authorized or tracked in another ratemaking account.6

PROPOSED TARIFF CHANGES

Pursuant to the Decision, SCE is establishing Preliminary Statement Part N.27, WMPMA, to track the costs of SCE’s approved WMP that are incremental to costs requested and/or approved for recovery in SCE’s GRC and GSRP Application, and not otherwise recorded in another ratemaking account.

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.

N. MEMORANDUM ACCOUNTS (Continued)

27. Wildfire Mitigation Plan Memorandum Account

a. Purpose

Pursuant to California Public Utilities Commission Decision (D.)19-05-038 and Public Utilities Code § 8386(e), the purpose of the Wildfire Mitigation Plan Memorandum Account (WMPMA) is to track costs incurred to implement SCE’s Wildfire Mitigation Plan (WMP) that are not otherwise covered in SCE’s revenue requirements or tracked in another ratemaking account. Costs tracked in the WMPMA will not include costs approved for recovery in SCE General Rate Cases (GRCs) or costs recorded to other memorandum accounts, such as SCE’s Catastrophic Event Memorandum Account (CEMA), Fire Hazard Prevention Memorandum Account (FHPMA), Grid Safety and Resiliency Program Memorandum Account (GSRPMA), and the Fire Risk Mitigation Memorandum Account (FRMMA), as provided in Public Utilities Code § 8386(j).

b. Operation of the WMPMA

Monthly entries to the WMPMA shall be determined as follows: 1) A one-time debit entry to record the transfer of the WMP-related

balance previously tracked in the FRMMA; 2) A debit entry equal to the expenses incurred related to WMP; 3) A debit or credit entry equal to the revenue requirement based on the

incremental recorded capital costs related to fire risk mitigation work. Capital revenue requirements include depreciation expense, return on investment, federal and state income taxes, and property taxes associated with the costs of installed equipment;

4) A credit entry to record the transfer of amounts to or from other regulatory accounts as authorized by the Commission; and

5) Interest shall accrue monthly to the WMPMA by applying one-twelfth of the three-month Commercial Paper, as reported by the Federal Reserve, to the average monthly balance in the WMPMA.

c. Disposition and Review Procedures

. The costs tracked in the WMPMA shall be presented to the Commission for review of reasonableness and recovery in a future GRC application, consistent with Public Utilities Code Section 8386(g). Costs tracked in the WMPMA may be recovered in rates only after a request by SCE, a showing of reasonableness, and approval by the Commission.
