Ms. Kimberly D. Bose, Secretary

Federal Energy Regulatory Commission

888 First Street, N.E.

Washington, DC 20426

Dear Ms. Bose:

Pursuant to Section 35.13 of the Federal Energy Regulatory Commission’s

(“Commission”) Regulations under the Federal Power Act (18 C.F.R. § 35.13), Southern

California Edison Company (“SCE”) tenders for filing revisions to its Transmission

Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual

update of the Transmission Revenue Balancing Account Adjustment (“TRBAA”).

The documents submitted with this filing consist of this letter of transmittal and

all attachments hereto; the revised TO Tariff reflecting the revised TRBAA and TRBAA

rate proposed in this filing in both clean and redline formats; the Prepared Direct

Testimony of Jee Kim; the relevant Statements required under the Commission’s

Regulations; and workpapers supporting the revisions proposed herein.

Background

The TRBAA is a ratemaking mechanism designed to ensure that all Transmission

Revenue Credits are flowed-through to transmission customers. Section 5.5 of the TO

Tariff identifies the items subject to the Transmission Revenue Balancing Account

(“TRBA”) and sets forth the procedure for revising the TRBAA on an annual basis. The

TRBAA is based on the balance in the TRBA as of September 30 of the current year, and

Ms. Kimberly D. Bose, Secretary

Federal Energy Regulatory Commission

a forecast of the Transmission Revenue Credits expected to be received in the following

year.

TRBAA

The revised TRBAA applicable to retail service is a negative $121,668,279 and

the revised retail TRBAA Rate is a negative $0.00144 per kilowatt-hour to be effective

for retail TO Tariff transmission service rendered on and after January 1, 2018. This

amount is an $11,036,223 decrease from the currently-effective level of negative

$110,632,056. The proposed wholesale TRBAA is a negative $121,378,713, a decrease

of $11,009,957 from the currently-effective level of negative $110,368,756. The

decrease in the TRBAA reflects an increase in the forecast level of wheeling revenues.

SCE’s TRBAA and TRBAA Rate are described in the Prepared Testimony of Ms.

Jee Kim included with this filing.

Revised TO Tariff

The revised TRBAA and retail rate change proposed in this filing described above

are reflected in the revised Appendices I and III to the TO Tariff submitted with this

filing. SCE is also filing a revision to Section 5.5 of the TO Tariff. Specifically, SCE is

deleting Sections 5.5.1 and 5.5.2 since the referenced amortization is completed.

Effective Date and Waiver

As set forth in the TO Tariff, the TRBAA revisions are to become effective on

January 1, 2018. SCE respectfully requests the Commission to assign an effective date of

January 1, 2018 to the TRBAA revisions proposed herein.

5. Access Charges and Transmission Rates.

5.1 Low Voltage Access Charge.

The Low Voltage Access Charge shall be determined in accordance with the ISO Tariff.

The Low Voltage Access Charge customer shall pay the Participating TO a Low Voltage

Access Charge equal to the product of the Participating TO’s Low Voltage Access

Charge rate and the kilowatt-hours of transmission service provided under the ISO Tariff

to the Low Voltage Access Charge customer. The Participating TO shall not assess the

Low Voltage Access Charge to any other Participating TO for transmission service over

Low Voltage Transmission Facilities that such other Participating TO receives and pays

for under an Existing Contract. Where a customer receives deliveries of energy at

voltage levels both above and below 200 kV, the Low Voltage Access Charge shall be

applied only to the kilowatt hours of energy delivered at voltage levels lower than 200

kV. The Participating TO’s monthly charge to be applied to Low Voltage Access Charge

customers is set forth in Appendix II herein.

5.2 Wheeling Access Charge.

The Wheeling Access Charge shall be determined in accordance with the the ISO Tariff.

The Wheeling Access Charge, assessed by the ISO, consists of a High Voltage

Wheeling Access Charge and, if applicable, a Low Voltage Wheeling Access Charge.

The High Voltage Wheeling Access Charge is set forth in the ISO Tariff. The

Participating TO's Low Voltage Wheeling Access Charge is set forth in Appendix II

herein.

FERC Electric Tariff, Third Revised Volume No. 6

5.3 End-User Transmission Rates.

End-User transmission rates for a FERC-jurisdictional Participating TO shall be based

on the Base Transmission Revenue Requirement authorized by FERC. In addition, all

End-Use Customers of a FERC-jurisdictional Participating TO shall be subject to the

FERC-authorized TRBAA rate and TACBAA rate. For a Local Publicly Owned Electric

Utility that is a Participating TO, such rates shall be submitted to the ISO for information

only. In addition, all customers of a Local Publicly Owned Electric Utility that is a

Participating TO shall be subject to the Local Regulatory Authority authorized TRBAA,

which shall also be submitted to the ISO. The Participating TO's End-User transmission

rates, by retail rate schedule, are set forth in Appendix III. An End-User shall pay the

same End-User transmission rate as other similarly situated End-Use Customers of the

Participating TO regardless of its energy supplier. End-Users withdrawing power from

the Participating TO's transmission or distribution facilities shall not qualify for

transmission access under the Wheeling Access Charge if FERC would be prohibited

from ordering transmission service for such customer by Section 212(h) of the FPA.

5.4 Transmission Revenue Requirement.

As set forth in the ISO Tariff, the Transmission Revenue Requirement for each

Participating TO shall be used to develop the Access Charges set forth in the ISO Tariff.

The Transmission Revenue Requirement, High Voltage Transmission Revenue

Requirement, and Low Voltage Transmission Revenue Requirement for the

Participating TO are set forth in Appendix I.

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

5.5 Transmission Revenue Balancing Account Adjustment (TRBAA).

The Participating TO shall maintain a Transmission Revenue Balancing Account

("TRBA") that will ensure that all Transmission Revenue Credits and the refunds,

specified in Sections 6 and 8 of Appendix F, Schedule 3 of the ISO Tariff, associated

with transmission service are flowed through to customers taking transmission service

from the ISO. The TRBAA shall be equal to:

TRBAA = Cr + Cf + I + FF&U Where:

Cr = The principal balance in the TRBA recorded in FERC Account No. 254 as

of September 30 of the year prior to commencement of the January billing

cycle. This balance represents the unamortized balance in the TRBA from

the previous period and the difference in the amount of revenues from

Transmission Revenue Credits and the amount of such revenues that has

been refunded to customers through operation of the TRBAA, adjusted for

franchise fees and uncollectable accounts expense;

Cf = The forecast of Transmission Revenue Credits for the following

calendar year;

I = The interest balance for the TRBA, which shall be calculated using

the interest rate pursuant to Section 35.19(a) of FERC’s regulations

under the Federal Power Act (18 CFR Section 35.19(a)). Interest

shall be calculated based on the average TRBA principal balance

each month, compounded quarterly; and

Page 17: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

FF&U = An adjustment for franchise fees and, if applicable, uncollectable

accounts expense.

Beginning in January of each year, the bills of End-Use Customers of the Participating

TO shall include, as a component of the End-User transmission rates, a TRBAA rate per

kilowatt-hour (rounded to the nearest $0.00001) equal to:

TRBAA Rate = TRBAA S

Where:

S = The total kilowatt-hours of Gross Load measured at the customer-meter

level as recorded for the twelve month period ending September 30 of the

year prior to commencement of the January billing cycle.

5.6 Transmission Access Charge Balancing Account Adjustment (TACBAA).

Commencing on the transition date determined under Section 4 of Schedule 3 to

Appendix F of the ISO Tariff, the Participating TO shall maintain a Transmission Access

Charge Balancing Account (TACBA). Each month the Participating TO shall make two

entries to the TACBA. One entry will equal the difference between (i) the actual

charges by the ISO to the Participating TO pursuant to Section 26.1.2 of the ISO Tariff

for the High Voltage Access Charge and Transition Charge and (ii) the revenues

disbursed by the ISO to the Participating TO pursuant to Section 26.1.3 of the ISO

Tariff. The second entry will equal the TACBAA rate revenues, adjusted for franchise

fees and uncollectable accounts expense, billed to End-Use Customers during the

month. Interest on the amounts accumulated in the TACBA shall be calculated based

on the average TACBA principal balance each month, compounded quarterly, using the

Page 18: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

interest rate pursuant to Section 35.19(a) of FERC's regulations under the Federal

Power Act (18 CFR Section 35.19(a)). For service rendered on and after the effective

date of new retail rates, authorized by the CPUC, modifying the frozen retail rates

established pursuant to California Assembly Bill 1890, the bills of End-Use Customers

of the Participating TO shall include, as a component of the End-User transmission

rates, a TACBAA rate per kilowatt-hour (rounded to the nearest $0.00001) equal to:

TACBAA Rate = Br + Bf - Rf + FF&U S

Where:

Br = The balance in the TACBA, including interest, as of the end of

February prior to the commencement of the June billing cycle;

Bf = A forecast of the annual Access Charge billings from the ISO;

Rf = A forecast of the annual revenues disbursed by the ISO to the

Participating TO pursuant to Section 26.1.3 of the ISO Tariff;

FF&U = An adjustment for franchise fees and uncollectable accounts

expense; and

S = The total kilowatt-hours of Gross Load measured at the customer-

meter level as recorded for the twelve-month period ending

February prior to commencement of the June billing cycle.

The TACBAA shall be revised effective June 1 of each year; however, nothing herein

shall preclude the Participating TO from filing with the FERC to revise the TACBAA rate

at any other time.

5.3 End-User Transmission Rates.

End-User transmission rates for a FERC-jurisdictional Participating TO shall be based

on the Base Transmission Revenue Requirement authorized by FERC. In addition, all

End-Use Customers of a FERC-jurisdictional Participating TO shall be subject to the

FERC-authorized TRBAA rate and TACBAA rate. For a Local Publicly Owned Electric

Utility that is a Participating TO, such rates shall be submitted to the ISO for information

only. In addition, all customers of a Local Publicly Owned Electric Utility that is a

Participating TO shall be subject to the Local Regulatory Authority authorized TRBAA,

which shall also be submitted to the ISO. The Participating TO's End-User transmission

rates, by retail rate schedule, are set forth in Appendix III. An End-User shall pay the

same End-User transmission rate as other similarly situated End-Use Customers of the

Participating TO regardless of its energy supplier. End-Users withdrawing power from

the Participating TO's transmission or distribution facilities shall not qualify for

transmission access under the Wheeling Access Charge if FERC would be prohibited

from ordering transmission service for such customer by Section 212(h) of the FPA.

5.4 Transmission Revenue Requirement.

As set forth in the ISO Tariff, the Transmission Revenue Requirement for each

Participating TO shall be used to develop the Access Charges set forth in the ISO Tariff.

5.5 Transmission Revenue Balancing Account Adjustment (TRBAA).

The Participating TO shall maintain a Transmission Revenue Balancing Account

("TRBA") that will ensure that all Transmission Revenue Credits and the refunds,

specified in Sections 6 and 8 of Appendix F, Schedule 3 of the ISO Tariff, associated

with transmission service are flowed through to customers taking transmission service

from the ISO. The TRBAA shall be equal to:

TRBAA = Cr + Cf + I + FF&U Where:

Cr = The principal balance in the TRBA recorded in FERC Account No. 254 as

of September 30 of the year prior to commencement of the January billing

cycle. This balance represents the unamortized balance in the TRBA from

the previous period and the difference in the amount of revenues from

Transmission Revenue Credits and the amount of such revenues that has

been refunded to customers through operation of the TRBAA, adjusted for

franchise fees and uncollectable accounts expense;

Cf = The forecast of Transmission Revenue Credits for the following

calendar year;

I = The interest balance for the TRBA, which shall be calculated using

the interest rate pursuant to Section 35.19(a) of FERC’s regulations

under the Federal Power Act (18 CFR Section 35.19(a)). Interest

shall be calculated based on the average TRBA principal balance

each month, compounded quarterly; and

Page 26: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

FF&U = An adjustment for franchise fees and, if applicable, uncollectable

accounts expense.

Beginning in January of each year, the bills of End-Use Customers of the Participating

TO shall include, as a component of the End-User transmission rates, a TRBAA rate per

kilowatt-hour (rounded to the nearest $0.00001) equal to:

TRBAA Rate = TRBAA S

Where:

S = The total kilowatt-hours of Gross Load measured at the customer-meter

level as recorded for the twelve month period ending September 30 of the

year prior to commencement of the January billing cycle.

5.5.1 ETC Cost Differentials Subaccount.

5.5.1.1 Beginning on October 1, 2006 and continuing until October 5,

2008, the TRBAA Rate applicable to End-Use Customers shall be

increased by $0.00063 per kilowatt-hour to recover over a two year

period the ETC Cost Differentials, which are a component of

Transmission Revenue Credits, paid by the Participating TO from

April 1, 1998 through September 30, 2005. The Participating TO

shall maintain a separate subaccount to the TRBA to reflect the

amortization of such previously unrecovered costs. This

subaccount shall include interest calculated using the interest rate

pursuant to Section 35.19(a) of FERC’s regulations under the

Federal Power Act (18 CFR Section 35.19(a)). Interest shall be

Page 27: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

calculated based on the average subaccount balance each month,

compounded quarterly. On October 5, 2008, the subaccount shall

be eliminated and any balance in the subaccount shall be

transferred to the TRBA.

5.5.1.2 For purposes of the calculation of the wholesale Transmission

Revenue Requirement and the charges for wholesale transmission

service set forth in Appendices I and II, respectively, beginning on

October 1, 2006 and continuing until October 5, 2008, the

wholesale TRBAA shall be adjusted by $2,175,883 to reflect a two

year amortization of the ETC Cost Differentials that are: (1) paid by

the Participating TO through September 30, 2005, and (2)

associated with service rendered on and after January 1, 2003.

This amount is composed of $1,529,493 associated with existing

High Voltage Transmission Facilities, $473,581 associated with

New High Voltage Transmission Facilities and $172,809 associated

with Low Voltage Transmission Facilities.

5.6 Transmission Access Charge Balancing Account Adjustment (TACBAA).

Commencing on the transition date determined under Section 4 of Schedule 3 to

Appendix F of the ISO Tariff, the Participating TO shall maintain a Transmission Access

Charge Balancing Account (TACBA). Each month the Participating TO shall make two

entries to the TACBA. One entry will equal the difference between (i) the actual

charges by the ISO to the Participating TO pursuant to Section 26.1.2 of the ISO Tariff

for the High Voltage Access Charge and Transition Charge and (ii) the revenues

Page 28: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

disbursed by the ISO to the Participating TO pursuant to Section 26.1.3 of the ISO

Tariff. The second entry will equal the TACBAA rate revenues, adjusted for franchise

fees and uncollectable accounts expense, billed to End-Use Customers during the

month. Interest on the amounts accumulated in the TACBA shall be calculated based

on the average TACBA principal balance each month, compounded quarterly, using the

interest rate pursuant to Section 35.19(a) of FERC's regulations under the Federal

Power Act (18 CFR Section 35.19(a)). For service rendered on and after the effective

date of new retail rates, authorized by the CPUC, modifying the frozen retail rates

established pursuant to California Assembly Bill 1890, the bills of End-Use Customers

of the Participating TO shall include, as a component of the End-User transmission

rates, a TACBAA rate per kilowatt-hour (rounded to the nearest $0.00001) equal to:

TACBAA Rate = Br + Bf - Rf + FF&U S

Where:

Br = The balance in the TACBA, including interest, as of the end of

February prior to the commencement of the June billing cycle;

Bf = A forecast of the annual Access Charge billings from the ISO;

Rf = A forecast of the annual revenues disbursed by the ISO to the

Participating TO pursuant to Section 26.1.3 of the ISO Tariff;

FF&U = An adjustment for franchise fees and uncollectable accounts

expense; and

Page 29: UNITED STATES OF AMERICA BEFORE THE …...Owner Tariff (“TO Tariff”), FERC Electric Tariff, Volume No. 6, to reflect the annual update of the Transmission Revenue Balancing Account

Southern California Edison Company

FERC Electric Tariff, Third Revised Volume No. 6

S = The total kilowatt-hours of Gross Load measured at the customer-

meter level as recorded for the twelve-month period ending

within Edison’s Regulatory Affairs organizational unit. My primary 8

responsibilities include providing analysis and policy guidance supporting 9

the development of pricing and related rate terms associated with contracts 10

and services subject to the jurisdiction of the Federal Energy Regulatory 11

Commission (“FERC” or “Commission”). 12

Q. Briefly describe your educational and professional background. 13

A. I received a Bachelor of Arts degree in Economics from the University of 14

California Irvine in September 2003. In February 2008, I joined SCE as a 15

Financial Analyst in the Regulatory Policy and Affairs Department, where 16

case and annual Formula Updates, supporting the development of the 1

annual filing for SCE Construction Work In Progress (“CWIP”) Balancing 2

Account, and supporting the development of Wholesale Distribution 3

Access Charges for wholesale load customers. 4

Q. Have you submitted testimony to the Commission previously? 5

A. No. 6

PURPOSE OF TESTIMONY 7

Q. What is the purpose of your testimony in this proceeding? 8

A. The purpose of my testimony is to present SCE’s Transmission Revenue 9

Balancing Account Adjustment (“TRBAA”) and associated TRBAA rate 10

applicable to End-User Customers (retail customers) proposed to become 11

effective January 1, 2018. 12

Q. What is the TRBAA? 13

A. The TRBAA mechanism has been a key component of the development 14

and recovery of Transmission Revenue Requirements (“TRRs”) in 15

California since initiation of the new market structure in 1998. The 16

TRBAA is a ratemaking mechanism, set forth in Section 5.5 of SCE’s 17

Transmission Owner Tariff (“TO Tariff”), that flows-through to 18

transmission customers all Transmission Revenue Credits (“TRCs”) 19

received by SCE. 20

Q. How does the TRBAA mechanism operate? 21

A. Under the TO Tariff, the TRBAA and TRBAA rate are to be updated 22

annually effective January 1. The updated TRBAA is to be based on the 23

balance in the Transmission Revenue Balancing Account (“TRBA”) as of 24

September 30 of the current year and the forecast of TRCs expected to be 25

received in the following year. 26

Southern California Edison Company

Docket No. ER18-___-000

Exhibit No. SCE-1

Page 4

Q. How is the TRBAA assessed to transmission customers? 1

A. As described in the TO Tariff, a separately stated per kWh rate is developed 2

for assessing the TRBAA to End-Use Customers. This rate is based on the 3

TRBAA divided by SCE’s deliveries to End-Use Customers (“Gross 4

Load”). In the case of wholesale transmission customers, there is no 5

separate per kWh TRBAA rate. Rather, the TRBAA is added to the Base 6

TRR and Standby revenue components to yield the wholesale TRR. Then, 7

in accordance with the California Independent System Operator 8

Corporation (“ISO”) Tariff, the wholesale TRR is split into High Voltage 9

and Low Voltage components. Once developed, SCE provides the 10

resulting High Voltage TRR to the ISO for its development of the High 11

Voltage Access Charges and High Voltage Wheeling Access Charges to be 12

effective on January 1. SCE calculates its Low Voltage Access Charge and 13

the Low Voltage Wheeling Access Charge by dividing the Low Voltage 14

TRR by Gross Load. SCE calculates its High Voltage Existing Contracts 15

Access Charge and Low Voltage Existing Contracts Access Charge by 16

dividing the appropriate voltage TRR by the sum of Edison’s twelve 17

monthly retail system peak demands measured at the ISO Controlled Grid 18

level consistent with such revenue requirement in accordance with its TO 19

Tariff. 20

Q. What is the proposed TRBAA to be applicable to SCE’s retail 21

transmission customers on January 1, 2018? 22

A. As shown in Statement BK and Appendix I of the revised TO Tariff, the 23

TRBAA applicable to retail customers for service rendered beginning on 24

January 1, 2018 is a negative $121.7 million, a decrease of $11.1 million 25

from the currently-effective level of negative $110.6 million. This amount 26

Southern California Edison Company

Docket No. ER18-___-000

Exhibit No. SCE-1

Page 5

is equal to a forecast of the TRCs for 2018 and the balance in the TRBA as 1

of September 30, 2017 as described below. 2

Q. Please explain the forecast of TRCs. 3

A. The forecast of TRCs for 2018 has two components—Wheeling revenue 4

and ETC Cost Differentials. Each component of the TRCs was forecast 5

separately. 6

Q. How was the forecast of Wheeling revenue developed? 7

A. The forecast of Wheeling revenue is based on the actual Wheeling revenue 8

SCE received from the ISO for Wheeling service reflected in the TRBAA 9

during the 12-month period ending September 2017. 10

Q. How was the forecast of ETC Cost Differentials developed? 11

A. The forecast of ETC Cost Differentials is based on the actual ETC Cost 12

Differentials reflected in the TRBAA during the 12-month period ending 13

September 2017. This forecast amount reflects the actual Scheduling 14

Coordinator costs SCE was billed by the ISO for transmission service under 15

the Exchange Agreement between the Los Angeles Department of Water 16

and Power (“LADWP”) and SCE, Rate Schedule FERC No. 219 17

(“Exchange Agreement”). 18

The forecast ETC Cost Differentials amount also reflects the value 19

of actual energy returned by LADWP to SCE in payment for transmission 20

losses to reflect the settlement in Docket Nos. ER03-1094, ER07-955, and 21

EL03-214, which became effective on January 14, 2008 (“Settlement”). 22

Q. Please describe the proposed TRBAA applicable to wholesale 23

transmission customers. 24

A. As shown in Statement BK and Appendix I of the revised TO Tariff, the 25

TRBAA applicable to wholesale customers for service beginning on 26

Southern California Edison Company

Docket No. ER18-___-000

Exhibit No. SCE-1

Page 6

January 1, 2018 is a negative $121.4 million, a decrease of $11.0 million 1

from the currently-effective level of negative $110.4 million. The 2

derivation of the forecast TRCs for 2018 for the wholesale TRBAA is the 3

same as described above for the retail TRBAA. Next, the TRBAA 4

applicable to wholesale transmission customers was separated into High 5

Voltage and Low Voltage components. 6

Q. How did you split the TRBAA revenue requirement into High Voltage 7

and Low Voltage components in this filing? 8

A. In developing this filing, SCE reflected the methodology set forth in 9

Section 12.1(e) of Schedule 3 of Appendix F to the ISO Tariff. 10

That methodology is as follows: 11

Wheeling revenues associated with transactions exiting the ISO Grid at 12

High Voltage Scheduling Points or Take-Out Points were reflected as 13

High Voltage components; 14

Wheeling revenues associated with transactions exiting the ISO Grid at 15

Low Voltage Scheduling Points or Take-Out Points were attributed 16

between High Voltage and Low Voltage components based on the High 17

Voltage and Low Voltage Wheeling Access Charge rates assessed to 18

such transactions by the ISO; 19

Other Transmission Revenue Credits (ETC Cost Differentials) were 20

allocated between High Voltage and Low Voltage components on a 21

gross plant basis. 22

The gross plant percentages used in this filing are the ones set forth in 23

SCE’s 2018 formula transmission rate update informational filing (“2018 24

Formula Rate Update”). In accordance with the formula rate protocols, 25

Southern California Edison Company

Docket No. ER18-___-000

Exhibit No. SCE-1

Page 7

SCE will file the 2018 Formula Rate Update concurrently with its 1

successor rate proposal by October 31, 2017. 2

Q. Please discuss the derivation of SCE’s proposed retail TRBAA rate. 3

A. The TRBAA rate applicable to End-Use transmission customers beginning 4

on January 1, 2018, as set forth in Statement BL and Appendix III of the 5

revised TO Tariff, is a negative $0.00144 per kWh. As shown in Statement 6

BL, this rate is equal to the TRBAA of negative $121.7 million divided by 7

SCE’s Gross Load at the meter for the twelve month period ended 8

September 30, 2017. 9

Q. How did SCE determine Gross Load used to calculate the TRBAA rate 10

in this filing? 11

A. In this filing, SCE used recorded billed sales for the period October 2016 12

through September 2017 of 84,358 GWhs for the purpose of developing 13

End-Use TRBAA rate as shown in Statement BL. Total recorded delivered 14

sales for this period was 85,586 GWh. SCE is excluding from the recorded 15

sales those deliveries that resulted in no transmission revenues due to the 16

netting structure of the Net Energy Metering Program (“NEM Program”) 17

authorized by the California Public Utilities Commission (“CPUC”). This 18

proposal is consistent with the Commission acceptance of SCE’s proposed 19

retail rate change in FERC Docket No. ER17-250. 20

Q. Please describe the CPUC’s NEM Program. 21

A. Since 1996, SCE’s retail tariffs authorized by the CPUC have included an 22

NEM Program. This Program allows certain retail customers to net kWh 23

amounts of energy exported against amounts supplied to the customer over 24

the customer’s monthly billing period, and to further net bills over an 25

annual period. The NEM Program netting results in participants being 26

Southern California Edison Company

Docket No. ER18-___-000

Exhibit No. SCE-1

Page 8

billed for fewer kWh of energy than the amount of kWh that SCE supplies 1

to the customers, with some participants potentially being billed for zero 2

kWh of transmission service. In a recent decision (“the Successor Tariff 3

Decision”), the CPUC established a successor NEM tariff that eliminates 4

the current caps on the size of individual participating generation facilities 5

and on the total kWh of generation that can participate in the program. The 6

Successor Tariff Decision furthermore explicitly provides that the 7

transmission component of retail rates will be “bypassable,” i.e., subject to 8

netting as described above, and thus some kWh of retail energy supplied by 9

SCE will not yield transmission revenue. 10

Q. Why did SCE exclude NEM Program deliveries that are expected to 11

result in no revenue from the recorded sales in developing retail 12

TRBAA rate? 13

A. Instead of developing the TRBAA rate using delivered retail sales, SCE 14

believes that the TRBAA rate should reflect that not all retail delivered 15

energy is assessed transmission charges as a result of the NEM Program. 16

Thus, the TRBAA rate design should be based on SCE’s kWh deliveries 17

that are expected to result in transmission revenues to SCE. 18

Q. Are you proposing revised wholesale rates in this filing? 19

A. No. SCE will reflect the revised wholesale TRBAA proposed herein in its 20

2018 Formula Rate Update. The resulting wholesale rates will be set forth 21

in that filing. 22

Q. Have the revised TRBAA and the retail TRBAA rate been reflected in 23

SCE’s TO Tariff? 24

A. Yes. The revised TRBAA and the retail TRBAA rate are reflected in the 25

revised Appendices I and III to the TO Tariff included with this filing. 26

Notes:

1) Franchise Fees represent payments that SCE makes to municipal entities for the right to locate facilities within

the municipality.

Instructions:

1) Enter Franchise Fee and Uncollectibles Factors as approved by the California Public Utilities Commission ("CPUC")

in modules 1 and 2 above pursuant to Instruction 2. If approved factors changed during Prior Year, enter both,

and note period of time for which each applies in "From" and "To" columns, and number of days each was in effect

during the Prior Year in "Days in Prior Year" Column.

2) Franchise Fees Factor is calculated from CPUC Decision by dividing adopted Franchise Fees

by Total Operating Revenues less Franchise Fees. Uncollectibles Factor is calculated by

dividing adopted Uncollectibles expense by Total Operating revenues less Uncollectibles Expense. Resulting FF & U

Factors represent factors that, when applied to TRR without FF and U will correctly determine FF and U expense.

3) Calculate in module 3 the weighted average FF and U factors from the factors in modules 1 and 2 based

on the number of days each FF and U factor was in effect during the Prior Year at issue.

Percent Calculation

Prior Year FF Factor: 0.92309% ((L1 FF Factor * L1 Days) + (L2 FF Factor * L2 Days))/365

Prior Year U Factor: 0.24142% ((L3 U Factor * L3 Days) + (L4 U Factor * L4 Days))/365
