---------------------------------------------------------------------------
\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/index.html.
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/index.html. 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/index.html. 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.
