RATES COMMISSION ORDER NO.35156 -CASE NOS.AVU-E-21-01
AND AVU-G-21-01
BACKGROUND
On September 1,2021,the Commission issued Order No.35156 approving an all-party
settlement for a two-year rate plan in Case Nos.AVU-E-21-01 and AVU-G-21-Ol.
On July 15,2022,Avista Corporation ("Company")submitted a compliance filing with
tariff sheets reflecting rates for the second year of the two-year rate plan with an effective date of
September 1,2022.
On August 2,2022,the Company submitted substitute tariff sheets correcting for
mistakes in the originally submitted tariff sheets.
STAFF ANALYSIS
Staff recommends that the Commission approve the tariff sheets and subsequently
submitted substitute tariff sheets reflecting the second-year rates of the Company's two-year rate
plan approved through Commission Order No.35156 with an effective date of September 1,
2022.
The tariff sheets submitted on July 15,2022,are consistent with the terms of the
settlement stipulation approved by Commission Order No.35156 with one exception.Some of
the Street and Area Lighting rates were inadvertently not updated in the rates submitted as part of
the authorized stipulation.By updating the Street and Area Lighting rates in this compliance

filing,the Company will incur about an $8000 revenue shortfallto the $8 million increase
approved in the Stipulation.Staff does not believe this amount is material compared to an
overall increase of $8 million.
In addition,Staff discovered two issues with the tariff sheets originally submitted as part
of this compliance filing.First,Sheet 042 contained an inaccurate rate code that is not used by
current customers and is no longer open for new customers.Second,Sheet 076 contained a
description with a reference to another state.The Company submitted substitute tariff sheets to
correct these two errors.
RECOMMENDATION
Staff recommends that the Commission approve the tariff sheets and substitute tariff
sheets reflecting the second-year rates of the Company's two-year rate plan approvedthrough
Commission Order No.35156 with an effective date of September 1,2022.
COMMISSION DECISION
Does the Commission wish to accept the Company's submitted tariff sheets and
substitute tariff sheets with an effective date of September 1,2022?
