C.OTHER SETTLEMENT COMPONENTS
11.PCA Authorized Level of Expense.The new level of power supply revenues,
expenses,retail load,and Load Change Adjustment Rate resulting from the September 1,2023,
settlement revenue requirement for purposes of the monthly PCA mechanism calculations are
detailed in Appendix A.The Settling Parties agree to the following:
i.Authorized Net Power Supply.The Settling Parties agree to leave system
power supply expense as approved in Case No.AVU-E-2l-01 totaling
$149,279,000 (Power Supply),adjusted to reflect these items:(a.)90%
Palouse Wind and Rattlesnake Flat Wind;and (b.)Remove Columbia Basin
Hydro Transmission Project,discussed below,resulting in a revised system
net power supply expense of $177,585,000.
a.Palouse and Rattlesnake Flat Wind.As noted in ¶7.j.ii.above,the
Settling Parties agree to include the Palouse Wind and Rattlesnake
Flat Wind Power PPA in base rates at 90%.90%of actual net
power costs for these projects will then be compared to this 90%
base amount to calculate the base-to-actual difference that will be
reflected in the PCA mechanism.This adjustment increases system
net power supply expense $29,313,000.
b.Remove Columbia Basin Hydro Transmission Costs.As noted in ¶
7.j.iii.above,the Settling Parties agree to remove the cost of
Columbia Basis Hydro Transmission costs.This adjustment
decreases system net power supply expense by $1,007,000.
ATTACHMENT 1 EXHIBIT 19
ii.Authorized Transmission Revenues.The Settling Parties agree to leave
system transmission revenues as approved in Case No.AVU-E-21-Ol
totaling $23,471,000.
iii.Adjust Columbia Basin and Chelan 2023 -2033 Contracts.The Settling
Parties agree that the actual cost of the Chelan and the Columbia Basin
contracts will be included in the PCA using the lower of market cost or
contract cost,with the PCA description and methodologyas follows:
a.Avista agrees to protect Idaho customers against its executed
contracts resulting from the 2022 All-Source RFP with Columbia
Basin Hydro (CBH)and Chelan Public Utility District (Chelan),
from the potential of costs of each contract being higher than the
spot-market value of power.Avista will ensure the cost of each
contract does not exceed the time-valued delivery of power
calculated on a daily basis using the on and off-peak prices at the
Mid-Columbia trading hub,as reported by the Intercontinental
Exchange's on-and off-peak firm energy indices.The Settling
Parties agree to meet and confer to determine a calculation method
prior to the Company filing its 2024 PCA application.
b.Avista will recover some or all of the approximately$1.007 million
annual cost of Columbia Basin Hydro transmission not included in
base rates to the extent that market prices are higher than the
Columbia Basin Hydro generation contract price as determined in
11.iii.a.above.The Settling Parties agree to meet and confer to
ATTACHMENT 1 EXHIBIT 19
determine the calculation method prior to the Company filing its
2024 PCA.
12.Electric and Natural Gas Fixed Cost Adjustment Mechanisms Authorized Base.
The new level of baseline values for the electric and natural gas Fixed Cost Adjustment Mechanism
(FCA)resulting from the September 1,2023 and September l,2024,settlement revenue
requirements are detailed as follows:
Appendix B -September 1,2023 Electric FCA Base
Appendix C -September 1,2024 Electric FCA Base
Appendix D -September 1,2023 Natural Gas FCA Base
Appendix E -September 1,2024 Natural Gas FCA Base
13.Wildfire Balancing Account.The Settling Parties agree to revise the two-way
Wildfire O&M Expense Balancing Account authorized "base"level to $4.367 million annually,
effective September 1,2023.The incremental balance deferred,beyond the existing deferred
balance as of September 30,2022 being amortized over a 4-year period in this proceeding (see ¶7
c.above),will be included for review and recovery in future general rate cases.
14.Wildfire Resiliency Plan.The Settling Parties agree to the following Wildfire
Resiliency Plan ("WRP")changes:
(a)For the Distribution Risk Tree program,the Company will have a third party
conduct a study,within a year of Commission Order,to see what the most efficient
vegetation management cycle should be in their service area (i.e.,2-or 3-year cycles).
(b)The Company will develop a formal process for Undergrounding
Distribution Lines related to the WRP to include project criteria,a selection process,and
cost-benefit analysis for completed and future undergrounding distribution line projects
related to wildfire mitigation prior to the Company's next general rate case.
ATTACHMENT 1 EXHIBIT 19
(c)The Company will develop process guidelines,including a least-cost least-
risk analysis,to evaluate pilot projects and to convert them to full programs within a year
of a Commission Order.
(d)The Company will detail all relationships (such as BLM and Forest Service)
it has that may benefit the wildfire mitigation program,contribute to program costs,or
provide cost sharing opportunities in its WRP.
(e)The Company will detail all funding alternatives and sources it pursued in
its WRP and provide an analysis and a comparison of alternatives it considered for each
pilot,project,or program when it requests recovery for these costs,including,among other

Insurance Expense Balancing Account to defer the difference in actual insurance expense,up or
down,from the authorized "base"level of insurance expense included of $4.009 million for electric
and $714,000 for natural gas,effective September 1,2023.The balance in the deferral will be
included for review and recovery in future regulatory proceedings.
16.Regulatory Amortizations.The Settling Parties agree to the Regulatory
Amortizations as filed by the Company*,with the exception of the Wildfire Deferral amortizations
(i.e.Wildfire Resiliency Plan Deferred Expense and Wildfire Expense Balancing Account deferred
expense),which the Settling Parties agree to revise from a two-year amortization to a four-year
amortization,as discussed at ¶7 c.above.

requesting approval for its proposed change to electric and natural gas book depreciation rates.
To the extent depreciation rates included in this general rate case,or the effective date of approved
depreciation rates (i.e.September 1,2023),as proposed by the Company,vary from the
depreciation rates or effective date ultimately approved in Case Nos.AVU-E-23-02 and AVU-G-
23-02,the Company will defer the difference in depreciation expense included and approved in
this case,versus the actual depreciation expense approved per Case Nos.AVU-E-23-02 and AVU-
G-23-02 on a monthly basis,for review and recovery or return to customers in a future general rate
case.

on any particular cost of service methodology.In recognition,however,that certain rate schedules

6 Inclusion of the updated (proposed)depreciation study depreciation rates in this proceeding results in an overall
decrease in electric and natural gas annual depreciation expense from existing depreciation expense levels.
7 The Company also requested that the Commission approve deferred accounting treatment if allocated depreciation
rates are not approved by all jurisdictions prior to September 1,2023,resulting in a difference between allocated
depreciation expense included in Case Nos.AVU-E-23-01 and AVU-G-23-01,and allocated depreciation expense
ultimately approved in the Depreciation Case Nos.AVU-E-23-02 and AVU-G-23-02.
