NOTICE OF APPLICATION
NOTICE OF MODIFIED PROCEDURE ORDER NO. 35923 1
Service Date September 14, 2023
BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION

On August 24, 2023, pursuant to Order No. 35810, Avista Corporation d/b/a Avista
Utilities (“Company”) applied (“Application”) to the Public Utilities Commission
(“Commission”) for approval of its capacity deficiency period used for its avoided cost
calculations. The Company requested its Application be processed by Modified Procedure.
The Commission now issues this Notice of Application and Notice of Modified Procedure
setting deadlines for interested persons to comment on the Application and for the Company to
reply.
BACKGROUND
A capacity deficiency case is used to determine when new qualifying facilities begin
avoiding capacity costs for a utility and are therefore eligible to start receiving capacity payments.
See Order No. 32697. Originally, each utility was required to file its capacity deficiency date case
when a utility submitted its Integrated Resource Plan (“IRP”) to the Commission, and the capacity
deficiency determined through the IRP planning process would be the starting point subject to the
outcome of the proceeding. See Order No. 32697. In 2017, the Commission amended Order No.
32697 to require “that each Idaho electric utility shall submit its updated capacity deficiency filing
after the Commission has acknowledged its IRP report, rather than upon its IRP filing….” Order
No. 33917 at 4. On June 8, 2023, the Commission further adapted this instruction in Order No.
35810 and required Idaho Power Company, Rocky Mountain Power, and the Company (Avista)
to file a capacity deficiency case within 30 days of their respective IRPs being filed. The Company
filed its 2023 IRP on June 1, 2023.1
1 The Company stated that it originally submitted its Capacity Deficiency filing on June 20, 2023, but that it was not
received by the Commission.

NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that the Company stated that its 2023 IRP identified
January 1, 2034, as its capacity deficiency date.
YOU ARE FURTHER NOTIFIED that the Company stated that its estimated capacity
deficiency date was later than the capacity deficiency date initially estimated in its 2021 IRP
because the Company has acquired significant new resources since that time; the Company also
listed certain new resources in its Application.
YOU ARE FURTHER NOTIFIED that the Company represented that it did not include
any Colstrip data into its capacity filing because the exact official date of the transfer of that
resource to NorthWestern Energy was not yet known—although the Company did state that the
