SUPPLEMENTARY INFORMATION: On October 25, 2022, as part of Rate Order WAPA–175, FERC approved and confirmed on a final basis the following rate schedules for ancillary services applicable to the WALC BA through September 30, 2026: Rate Schedules DSW–SD4 (Scheduling, System Control, and Dispatch), DSW–RS4 (Reactive Supply and Voltage Control), DSW–FR4 (Regulation and Frequency Response), DSW–EI4 (Energy Imbalance), DSW– SPR4 (Spinning Reserves), DSW–SUR4 (Supplemental Reserves), and DSW–GI2 (Generator Imbalance).1 On September 15, 2021, WAPA and CAISO executed an Implementation Agreement to facilitate the WALC BA’s participation in CAISO’s real-time energy market effective April 5, 2023.2 WAPA’s decision to participate in CAISO’s EIM was the result of nearly two years of analysis and collaboration with customers and stakeholders on the best path forward to manage the realtime mismatches between supply and demand within the WALC BA. To accommodate the WALC BA’s participation in EIM and maintain revenue neutrality, new formula rates are required to pass through the financial settlements, administrative costs, and transaction fees incurred by the WALC BA. On January 9, 2023, WAPA’s Desert Southwest Region (DSW) published a 1 Order Confirming and Approving Rate Schedules on a Final Basis, Docket No. EF21–6–000 (Oct. 25, 2022). 2 FERC accepted the Implementation Agreement effective November 28, 2021, pursuant to a November 17, 2021, letter order in Docket No. ER21–2950. CAISO and WAPA subsequently executed, and CAISO filed with FERC, several participation agreements governing the WALC BA’s participation in EIM. FERC accepted the participation agreements effective November 2, 2022, pursuant to an October 21, 2022 letter order in Docket No. ER22–2786.

Public Notice and Comment WAPA’s Desert Southwest Region (DSW) followed the Procedures for Public Participation in Power and Transmission Rate Adjustments and Extensions, 10 CFR part 903, in developing these formula rates. DSW took the following steps to involve interested parties in the rate process: 1. On January 9, 2023, a Federal Register notice (88 FR 1220) announced the proposed formula rates and initiated a 30-day public consultation and comment period. 2. On January 10, 2023, DSW notified customers and interested parties of the proposed formula rates and provided a copy of the Federal Register notice by email. 3. DSW established a website to post information about the rate adjustment process. The website is located at www.wapa.gov/regions/DSW/Pages/ DSW-EIM.aspx. 4. During the 30-day consultation and comment period, which ended on February 8, 2023, DSW received no comments. ddrumheller on DSK120RN23PROD with NOTICES1 Ancillary Services Rate Discussion In accordance with WAPA’s Tariff and to maintain the reliability of transmission service, DSW currently provides the following ancillary services: (1) Scheduling, System Control and Dispatch (Rate Schedule DSW– SD4); (2) Reactive Supply and Voltage Control (Rate Schedule DSW–RS4); (3) Regulation and Frequency Response VerDate Sep<11>2014 21:09 Mar 13, 2023 Jkt 259001 (Rate Schedule DSW–FR4); (4) Energy Imbalance (Rate Schedule DSW–EI4); (5) Spinning Reserve (Rate Schedule DSW– SPR4); (6) Supplemental Reserves (Rate Schedule DSW–SUR4); and (7) Generator Imbalance (Rate Schedule DSW–GI2). The formula rates for these services are designed to recover the costs incurred for providing each of the services. To accommodate the WALC BA’s participation in the CAISO EIM, DSW has added the following ancillary services: (1) EIM Administrative Service (provisional Rate Schedule DSW– EIM1T), (2) EIM EI Service (provisional Rate Schedule DSW–EIM4T), and (3) EIM GI Service (provisional Rate Schedule DSW–EIM9T). The formula rates for these services are designed to pass through the costs resulting from the WALC BA’s participation in the CAISO EIM. EIM Administrative Service The CAISO assesses administrative service charges and transaction fees to recover the costs associated with operating the EIM and providing services to participants. Rate Schedule DSW–EIM1T facilitates the pass through of CAISO EIM administrative service charges and transaction fees to DSW transmission customers and ensures the WALC BA remains revenue neutral. This rate schedule aligns with WAPA’s Tariff and applies when the WALC BA participates in the CAISO EIM and when the EIM has not been suspended. The services provided under Rate Schedule DSW–SD4 continue to apply and the costs are included in the applicable transmission service rates. For clarity, when the WALC BA is participating in CAISO EIM, both Rate Schedules DSW–SD4 and DSW–EIM1T will apply. Transmission customers will be billed for their share of EIM Administrative Service charges allocated to the WALC BA for its participation in the CAISO EIM in accordance with DSW’s EIM business practice posted on its OASIS at www.oasis.oati.com/walc/. Revisions to the CAISO’s Tariff may require changes to DSW’s EIM business practice, which would be processed consistent with section 4.3 of WAPA’s Tariff. EIM Energy Imbalance Service EI service is provided when a difference occurs between the scheduled and actual delivery of energy to a load within the WALC BAA. DSW’s existing rate schedule for EI Service, DSW–EI4, does not address EIM participation or settlements. PO 00000 Frm 00074 Fmt 4703 Sfmt 4703 Rate Schedule DSW–EIM4T facilitates the pass through of any financial settlements for EI Service from the CAISO EIM to DSW transmission customers and ensures the WALC BA remains revenue neutral. This rate schedule aligns with WAPA’s Tariff and applies to EI Service when the WALC BA participates in the CAISO EIM and when the EIM has not been suspended. Rate Schedule DSW–EI4 applies when the WALC BA is not participating in EIM or when the EIM has been suspended. Transmission customers will be billed for their share of EIM EI Service charges incurred by the WALC BA for its participation in the CAISO EIM in accordance with the settlement methods in DSW’s EIM business practice posted on its OASIS at www.oasis.oati.com/ walc/. Revisions to the CAISO’s Tariff may require changes to DSW’s EIM business practice, which would be processed consistent with section 4.3 of WAPA’s Tariff. EIM Generator Imbalance Service GI service is provided when a difference occurs between the output of a generator located in the WALC BAA, and the delivery schedule from that generator to (1) another BAA or (2) a load within the WALC BAA. The EIM requires all participating resources to settle directly with the CAISO. Nonparticipating resources need to settle with the WALC BA, the EIM entity. DSW’s existing rate schedule for GI Service, DSW–GI2, does not address EIM participation or make a distinction between participating and nonparticipating resources. Rate Schedule DSW–EIM9T facilitates the pass through of any financial settlements for GI service from the CAISO EIM to DSW transmission customers and ensures the WALC BA remains revenue neutral. This rate schedule aligns with WAPA’s Tariff and applies to GI service when the WALC BA participates in the CAISO EIM and when the EIM has not been suspended. Rate Schedule DSW–GI2 applies when the WALC BA is not participating in EIM or when the EIM has been suspended. Transmission customers will be billed for their share of EIM GI Service charges incurred by the WALC BA for its participation in the CAISO EIM in accordance with the settlement methods in DSW’s EIM business practice posted on its OASIS at www.oasis.oati.com/ walc/. Revisions to the CAISO’s Tariff may require changes to DSW’s EIM business practice, which would be processed consistent with section 4.3 of WAPA’s Tariff.

SUPPLEMENTARY INFORMATION: On October 25, 2022, as part of Rate Order 
WAPA-175, FERC approved and confirmed on a final basis the following 
rate schedules for ancillary services applicable to the WALC BA through 
September 30, 2026: Rate Schedules DSW-SD4 (Scheduling, System Control, 
and Dispatch), DSW-RS4 (Reactive Supply and Voltage Control), DSW-FR4 
(Regulation and Frequency Response), DSW-EI4 (Energy Imbalance), DSW-
SPR4 (Spinning Reserves), DSW-SUR4 (Supplemental Reserves), and DSW-GI2 
(Generator Imbalance).\1\

    \1\ Order Confirming and Approving Rate Schedules on a Final 
Basis, Docket No. EF21-6-000 (Oct. 25, 2022).
---------------------------------------------------------------------------

    On September 15, 2021, WAPA and CAISO executed an Implementation 
Agreement to facilitate the WALC BA's participation in CAISO's real-
time energy market effective April 5, 2023.\2\ WAPA's decision to 
participate in CAISO's EIM was the result of nearly two years of 
analysis and collaboration with customers and stakeholders on the best 
path forward to manage the real-time mismatches between supply and 
demand within the WALC BA. To accommodate the WALC BA's participation 
in EIM and maintain revenue neutrality, new formula rates are required 
to pass through the financial settlements, administrative costs, and 
transaction fees incurred by the WALC BA.
---------------------------------------------------------------------------

    \2\ FERC accepted the Implementation Agreement effective 
November 28, 2021, pursuant to a November 17, 2021, letter order in 
Docket No. ER21-2950. CAISO and WAPA subsequently executed, and 
CAISO filed with FERC, several participation agreements governing 
the WALC BA's participation in EIM. FERC accepted the participation 
agreements effective November 2, 2022, pursuant to an October 21, 
2022 letter order in Docket No. ER22-2786.
---------------------------------------------------------------------------

    On January 9, 2023, WAPA's Desert Southwest Region (DSW) published 
a Federal Register notice (88 FR 1220) that proposed three new formula 
rates for EIM: EIM Administrative Service, EIM EI Service, and EIM GI 
Service and initiated a 30-day public consultation and comment period.

Public Notice and Comment

    WAPA's Desert Southwest Region (DSW) followed the Procedures for 
Public Participation in Power and Transmission Rate Adjustments and 
Extensions, 10 CFR part 903, in developing these formula rates. DSW 
took the following steps to involve interested parties in the rate 
process:
    1. On January 9, 2023, a Federal Register notice (88 FR 1220) 
announced the proposed formula rates and initiated a 30-day public 
consultation and comment period.
    2. On January 10, 2023, DSW notified customers and interested 
parties of the proposed formula rates and provided a copy of the 
Federal Register notice by email.
    3. DSW established a website to post information about the rate 
adjustment process. The website is located at www.wapa.gov/regions/DSW/Pages/DSW-EIM.aspx.
    4. During the 30-day consultation and comment period, which ended 
on February 8, 2023, DSW received no comments.

Ancillary Services Rate Discussion

    In accordance with WAPA's Tariff and to maintain the reliability of 
transmission service, DSW currently provides the following ancillary 
services: (1) Scheduling, System Control and Dispatch (Rate Schedule 
DSW-SD4); (2) Reactive Supply and Voltage Control (Rate Schedule DSW-
RS4); (3) Regulation and Frequency Response (Rate Schedule DSW-FR4); 
(4) Energy Imbalance (Rate Schedule DSW-EI4); (5) Spinning Reserve 
(Rate Schedule DSW-SPR4); (6) Supplemental Reserves (Rate Schedule DSW-
SUR4); and (7) Generator Imbalance (Rate Schedule DSW-GI2). The formula 
rates for these services are designed to recover the costs incurred for 
providing each of the services.
    To accommodate the WALC BA's participation in the CAISO EIM, DSW 
has added the following ancillary services: (1) EIM Administrative 
Service (provisional Rate Schedule DSW-EIM1T), (2) EIM EI Service 
(provisional Rate Schedule DSW-EIM4T), and (3) EIM GI Service 
(provisional Rate Schedule DSW-EIM9T). The formula rates for these 
services are designed to pass through the costs resulting from the WALC 
BA's participation in the CAISO EIM.

EIM Administrative Service

    The CAISO assesses administrative service charges and transaction 
fees to recover the costs associated with operating the EIM and 
providing services to participants. Rate Schedule DSW-EIM1T facilitates 
the pass through of CAISO EIM administrative service charges and 
transaction fees to DSW transmission customers and ensures the WALC BA 
remains revenue neutral. This rate schedule aligns with WAPA's Tariff 
and applies when the WALC BA participates in the CAISO EIM and when the 
EIM has not been suspended. The services provided under Rate Schedule 
DSW-SD4 continue to apply and the costs are included in the applicable 
transmission service rates. For clarity, when the WALC BA is 
participating in CAISO EIM, both Rate Schedules DSW-SD4 and DSW-EIM1T 
will apply.
    Transmission customers will be billed for their share of EIM 
Administrative Service charges allocated to the WALC BA for its 
participation in the CAISO EIM in accordance with DSW's EIM business 
practice posted on its OASIS at www.oasis.oati.com/walc/. 
Revisions to the CAISO's Tariff may require changes to DSW's EIM 
business practice, which would be processed consistent with section 4.3 
of WAPA's Tariff.

EIM Energy Imbalance Service

    EI service is provided when a difference occurs between the 
scheduled and actual delivery of energy to a load within the WALC BAA. 
DSW's existing rate schedule for EI Service, DSW-EI4, does not address 
EIM participation or settlements.
    Rate Schedule DSW-EIM4T facilitates the pass through of any 
financial settlements for EI Service from the CAISO EIM to DSW 
transmission customers and ensures the WALC BA remains revenue neutral. 
This rate schedule aligns with WAPA's Tariff and applies to EI Service 
when the WALC BA participates in the CAISO EIM and when the EIM has not 
been suspended. Rate Schedule DSW-EI4 applies when the WALC BA is not 
participating in EIM or when the EIM has been suspended.
    Transmission customers will be billed for their share of EIM EI 
Service charges incurred by the WALC BA for its participation in the 
CAISO EIM in accordance with the settlement methods in DSW's EIM 
business practice posted on its OASIS at www.oasis.oati.com/walc/. Revisions to the CAISO's Tariff may require changes to 
DSW's EIM business practice, which would be processed consistent with 
section 4.3 of WAPA's Tariff.

EIM Generator Imbalance Service

    GI service is provided when a difference occurs between the output 
of a generator located in the WALC BAA, and the delivery schedule from 
that generator to (1) another BAA or (2) a load within the WALC BAA. 
The EIM requires all participating resources to settle directly with 
the CAISO. Non-participating resources need to settle with the WALC BA, 
the EIM entity. DSW's existing rate schedule for GI Service, DSW-GI2, 
does not address EIM participation or make a distinction between 
participating and non-participating resources.
    Rate Schedule DSW-EIM9T facilitates the pass through of any 
financial settlements for GI service from the CAISO EIM to DSW 
transmission customers and ensures the WALC BA remains revenue neutral. 
This rate schedule aligns with WAPA's Tariff and applies to GI service 
when the WALC BA participates in the CAISO EIM and when the EIM has not 
been suspended. Rate Schedule DSW-GI2 applies when the WALC BA is not 
participating in EIM or when the EIM has been suspended.
    Transmission customers will be billed for their share of EIM GI 
Service charges incurred by the WALC BA for its participation in the 
CAISO EIM in accordance with the settlement methods in DSW's EIM 
business practice posted on its OASIS at www.oasis.oati.com/walc/. Revisions to the CAISO's Tariff may require changes to 
DSW's EIM business practice, which would be processed consistent with 
section 4.3 of WAPA's Tariff.

the Western Area Lower Colorado (WALC) Balancing Authority (BA) 
participates in the California Independent System Operator's (CAISO) 
Energy Imbalance Market (EIM) and when the EIM has not been suspended. 
Rate Schedule DSW-EI4 or its superseding rate schedule would apply when 
the WALC BA is not participating or when the EIM has been suspended.
    The CAISO EIM provides energy to the WALC BA when there is a 
difference between the scheduled and actual delivery of energy to a 
load within the WALC BA Area. These differences (energy imbalances) 
result in financial settlements between the CAISO and the WALC BA. Any 
financial settlements for energy imbalances associated with the WALC 
BA's participation in the EIM will be passed through to ensure the WALC 
BA remains revenue neutral.

Formula Rate

    Charges for EI Service shall reflect the pass through of all 
applicable costs associated with the WALC BA's participation in the EIM 
that are assessed by the CAISO to the WALC BA. Costs shall be 
identified by a CAISO charge code and passed through to transmission 
customers using the settlement methods detailed in Desert Southwest 
Region's (DSW) EIM business practice posted on its Open Access Same-
time Information System (OASIS) at www.oasis.oati.com/walc/. 
Revisions to the CAISO's Tariff may require changes to DSW's EIM 
business practice, which would be processed consistent with section 4.3 
of WAPA's Tariff.

Charge Components

    Charges for EI Service will typically include one or more of the 
following items:

(Approved Under Rate Order No. WAPA-208)

Effective

    Beginning on April 5, 2023, and extending through September 30, 
2026, or until superseded by another rate schedule, whichever occurs 
earlier.

Applicable

    This rate schedule applies to Generator Imbalance (GI) Service when 
the Western Area Lower Colorado (WALC) Balancing Authority (BA) 
participates in the California Independent System Operator's (CAISO) 
Energy Imbalance Market (EIM) and when the EIM has not been suspended. 
Rate Schedule DSW-GI4 or its superseding rate schedule would apply when 
the WALC BA is not participating or when the EIM has been suspended.
    The CAISO EIM provides energy to the WALC BA when there is a 
difference between the scheduled and actual delivery of energy from a 
non-participating resource within the WALC BA Area. These differences 
(generator imbalances) result in financial settlements between the 
CAISO and the WALC BA. Any financial settlements for generator 
imbalances associated with the WALC BA's participation in the EIM will 
be passed through to ensure the WALC BA remains revenue neutral.

Formula Rate

    Charges for GI Service shall reflect the pass through of all 
applicable costs associated with the WALC BA's participation in the EIM 
that are assessed by the CAISO to the WALC BA. Costs shall be 
identified by a CAISO charge code and passed through to transmission 
customers using the settlement methods detailed in Desert Southwest 
Region's (DSW) EIM business practice posted on its Open Access Same-
time Information System (OASIS) at www.oasis.oati.com/walc/.
