(Avista) filed revisions to its Open Access Transmission Tariff (Tariff)to facilitate

mechanism for a generating resource to participate in the EIM; (3) the obligations of
Avista as an EIM Entity and EIM Entity Scheduling Coordinator; (4) the obligations of
Avista transmission customers to provide forecast data to Avista at certain intervals
before the start of the operating hour; (5)the provision of transmission capacity on Avista
transmission assets for EIM transfers, management of the transmission system during
normal and emergency operating conditions, and transmission and generation outage
reporting requirements; (6) the settlement and billing of EIM charges; (7) compliance
obligations of transmission customers, rules of conduct, and enforcement oversight of the
Commission with respect to the EIM; and (8) rules and procedures during market
contingencies. Avista requests that EIM-related provisions that do not affect settlement

Reference:Notice of Change in Status
On June 30, 2021, you filed on behalf of Avista Corporation (Avista) a notice of
change in status informing the Commission of its anticipated participation in the Energy
Imbalance Market (EIM)administered by California Independent System Operator
Corporation (CAISO). You state that Avista intends to begin participating in the EIM on
March 2, 2022. Your change in status is accepted for filing.
Your filing was noticed on July 9, 2021, with comments, protests or interventions
due on or before July 21, 2021. None was filed.
The Commission has stated that EIM participants must take into account whether
the existence of frequently-binding transmission constraints creates a separate relevant
geographic submarket that should be studied.1 The Commission has stated that “a
potential EIM participant is permitted to demonstrate that there are no frequently binding
transmission constraints that would limit imports into its home balancing authority area
(or the balancing authority area where its generation is located) such that the home
balancing authority area should not be deemed to be an EIM submarket itself, or to be
within an EIM submarket.”2 The Commission further stated that “[h]aving made such a
demonstration, there would be no need for a seller to submit a separate market power

analysis for its home balancing authority area.”3
Consistent with this guidance, you provided an analysis to demonstrate that the
Avista balancing authority area is not a submarket within the EIM footprint requiring a
separate market power analysis. Based on your representations, we find that Avista has
demonstrated that the Avista balancing authority area should not be deemed a submarket
within the EIM footprint, and a separate market power analysis is not required.
You submitted a market power analysis for the EIM footprint, which you represent
demonstrates that Avista passes both the pivotal supplier and wholesale market share
screens in that market.Based on your representations, Avista satisfies the Commission’s
requirements for market-based rate authority regarding horizontal and vertical market
power.

Avista is directed to submit a compliance filing, within 30 days of the date of the
issuance of this order, revising its market-based rate tariff to reflect that it is authorized to
transact at market-based rates in the CAISO EIM.
Avista must include an EIM price separation analysis in its future triennial updated
market power analyses.4
This action does not constitute approval of any service, rate, charge, classification,
or any rule, regulation, or practice affecting such rate or service provided for in the filed
documents; nor shall such action be deemed as recognition of any claimed contractual
right or obligation affecting or relating to such service or rate; and such acceptance is
without prejudice to any findings or orders which have been or may hereafter be made by
the Commission in any proceeding now pending or hereafter instituted by or against any
of the applicant(s).
This action is taken pursuant to the authority delegated to the Director, Division of
Electric Power Regulation -West, under 18 C.F.R. § 375.307. This order constitutes
final agency action. Requests for rehearing by the Commission may be filed within 30
days of the date of issuance of this order, pursuant to 18 C.F.R.§ 385.713.

analysis.”).
