PUBLIC UTILITIES COMMISSION OF THE STATE OF CALIFORNIA
ENERGY DIVISION
SUBJECT:
Establishment of the Microgrid Memorandum Account and
Microgrid One-Way Balancing Account Pursuant to Decision
21-01-018
In compliance with Decision (D.) 21-01-018, 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 and are attached hereto.
PURPOSE
Pursuant to Ordering Paragraphs (OPs) 7 and 8 of D.21-01-018 (Decision), SCE
submits this advice letter to establish: (1) Preliminary Statement Part SSS, the Microgrid
One-Way Balancing Account (MOWBA), to record evaluation and implementation costs
associated with the isolation technologies and microgrids; the MOWBA includes two
subaccounts: Electrical Isolation Technology Evaluation and Microgrids Evaluation; and,
(2) Preliminary Statement Part N.39, the Microgrid Memorandum Account (MMA), to
track: (a) the costs incurred to develop the Microgrid Incentive Program before approval
of the program implementation and (b) the other implementation requirements for
fulfilling Section 3.4.3 of the Decision.
In addition, SCE modifies Preliminary Statement Part YY, Base Revenue Requirement
Balancing Account (BRRBA), to record the annual ending balance transfer from the
MOWBA for cost recovery purposes from customers.1
BACKGROUND
On September 12, 2019, the Commission initiated Rulemaking (R.) 19-09-009 to
develop a policy framework to facilitate the commercialization of microgrids and related
resiliency strategies, and to implement Senate Bill (SB) 1339 (Stern, 2018). SB 1339
required the Commission, in consultation with the California Energy Commission, and
1
SCE will only transfer and seek cost recovery of amounts up to the approved cost cap for
the isolation technology and microgrid evaluations.

the California Independent System Operator to take specific actions to facilitate the
commercialization of microgrids for distribution customers of large electrical
corporations by December 1, 2020.
On December 20, 2019, the assigned Commissioner issued a Scoping Memo and
Ruling for Track 1 of R.19-09-009 that addressed deploying resiliency planning in areas
prone to outage events and wildfires, and invited utility proposals to be submitted for
consideration. On June 17, 2020, the Commission issued D.20-06-017, which adopted
the Track 1 short-term actions to: (1) accelerate microgrid deployment and
interconnection of resiliency projects in advance of the 2020 wildfire season; (2)
modernize existing tariffs to maximize social resiliency benefits; (3) promote
collaborative engagement between the utilities and governments; and (4) approve
resiliency proposals set forth by Pacific Gas and Electric Company (PG&E) and San
Diego Gas & Electric Company (SDG&E). The assigned Commissioner issued an
amended Scoping Memo and Ruling for Track 2 on July 3, 2020, which focused on
continouos implementation of SB 1339, including commercialization of microgrids,
reducing barriers to microgrid deployment statewide, and ensuring that non-benefiting
microgrid customers remain indifferent to costs. On January 21, 2021, the Commission
issued D.21-01-018, which adopted Track 2 actions, including microgrid tariffs and rules
to facilitate the commercialization of microgrids pursuant to Senate Bill 1339.
MICROGRID INCENTIVE PROGRAM AND MEMORANDUM ACCOUNT
In the Decision, Section 3.4.3 directs SCE to develop a Microgrid Incentive Program to
fund clean energy microgrids to support the critical needs of vulnerable populations
affected by a grid outage. The Investor-Owned Utilities (IOUs)2 must conduct joint
stakeholder outreach and engagement to solicit input on the design and implementation
of the Microgrid Incentive Program, the details of which are addressed in Advice 4424E. The IOU’s will submit a joint proposed implementation plan within 120 days after the
approval of Advice 4424-E. At minimum, the IOU’s will include the following in the joint
implementation plan: (1) program administrator’s reporting requirements and timeline;
(2) proposal for allocating program funding amongst the IOUs; (3) accounting and
ratemaking treatment for cost; (4) program administrative expenses cost cap
methodology; (5) development of a program delivery plan handbook; (6) program
evaluation description; (7) customers shall have access to a one-time matching funds
payment to offset some portion of the utility infrastructure upgrade costs associated with
implementing the islanding function of the microgrid; and (8) report on public
workshops.
Pursuant to OP 7 of the Decision, a Tier 1 advice letter shall be submitted to establish
the MMA to track: (a) the costs incurred to develop the Microgrid Incentive Program
pursuant to Section 3.4.3 of the Decision before approval of the program
implementation details and (b) the other implementation requirements for fulfilling

February 22, 2021
Section 3.4.3 of the Decision3. The costs tracked in MMA will be recovered from
distribution customers4 .
MICROGRID ONE-WAY BALANCING ACCOUNT
In this advice letter, SCE is establishing the Microgrid One-Way Balancing Account
(MOWBA) pursuant to OP 8 of the Decision,. The MOWBA will include two subaccounts
for: (1) electrical isolation technology evaluation; and (2) microgrids evaluation. The cost
for implementing the different isolation technologies pursuant to Section 3.5.3 and OP 9
of the Decision will record in the MOWBA and will be recovered in distribution rates
through the annual consolidated true-up advice letter. In addition, the Commission
authorized an overall cost cap budget of $3 million allocated5 across the InvestorOwned Utilities (IOUs)6 for the evaluation and implementation of the isolation
technologies. If an IOU requires a larger budget, it may include in its subsequent Tier 2
advice letter a request for a budgetary increase along with supporting justification
demonstrating the need.7
Additionally, the Commission directed the Energy Division to engage a neutral thirdparty contractor to review and evaluate the effectiveness of the changes to the electric
rules adopted by D.21-01-018, D.20-06-17, and the new microgrid tariff, microgrid
incentive programs, and the pilot studies of D.21-01-018. Costs for the third-party
contractor will record in the MOWBA and will be recovered in distribution rates through
the annual consolidated true-up advice letter, pursuant to OP 12. In the Decision, the
Commission authorized a $1 million budget cap for the evaluation, subject to a
downward adjustment by Energy Division.8
PROPOSED TARIFF CHANGES
As discussed above, and in accordance with OPs 7 and 8 of D.21-01-018, in this advice
letter SCE proposes the establishment of the following:
(1) Preliminary Statement Part N.39, MMA, to track: (a) the costs incurred to develop
the Microgrid Incentive Program prior to approval of the program implementation
and (b) the other implementation requirements for fulfilling Section 3.4.3 of the
Decision. SCE will seek review and recovery of amounts tracked in the MMA in its
Energy Resource Recovery Account (ERRA) Review or General Rate Case
proceeding.

(2) Preliminary Statement Part SSS, MOWBA, to record evaluation and
implementation costs associated with the isolation technologies and microgrids.
The MOWBA will include two subaccounts: (1) Electrical Isolation Technology
Evaluation and (2) Microgrids Evaluation. In addition, SCE will transfer the annual
ending balance in the MOWBA to the distribution subaccount of the BRRBA for
cost recovery from customers via distribution rates through the annual
consolidated true-up advice letter.
In addition, SCE modifies Preliminary Statement Part YY, BRRBA, to record the annual
ending balance transfer from the MOWBA for cost recovery purposes from customers.
This advice letter will not cause the withdrawal of service or conflict with any other
schedule or rule.
