CASE NOS. AVU-E-22-06
IPC-E-22-16
PETITION
The Staff of the Idaho Public Utilities Commission (“Staff”), in accordance with Idaho
Code §§ 61-501, -502, and -503, and applicable provisions of the Public Utility Regulatory Policies
Act of 1978 (“PURPA”) and pursuant to Commission Rule of Procedure 37 and 53, IDAPA
31.01.01.37 and .53, petitions the Idaho Public Utilities Commission (“Commission”) for an order
updating the Colstrip-related adjustable portion of the published avoided cost rates for existing
PURPA contracts.
In support of its Petition, Staff states:
I.BACKGROUND
Each July 1, the Commission updates Qualifying Facility (“QF”) contracts that use
published avoided cost rates calculated under the Colstrip Method. In Order No. 28708, Case No.
GNR-E-99-01, the Commission established a method for updating the annual adjustable-rate
portion of avoided costs for those QF contracts using variable costs associated with Colstrip—a
coal-fired generating facility in southeast Montana. For those QF contracts with Colstrip-related
fuel costs and variable O&M, the Commission directed that future Colstrip variable cost

adjustments are to be calculated by using Federal Energy Regulatory Commission (“FERC”) Form
1 Colstrip Unit Coal Costs per megawatt hour (“MWh”) and adding $2.00/MWh (the average
variable O&M cost of Colstrip plus 20¢/MWh for generation taxes plus a five percent adjustment
for line loss). Staff attached relevant pages from Avista’s FERC Form 1 as Attachment A.
As computed by Staff and shown below, the Colstrip-related adjustable rate will change
from 20.37 mill/kilowatt hour (“kWh”) to 19.13 mill/kWh, effective July 1, 2022.

II. PROCEDURE
Staff believes that a hearing is not necessary to consider the issues and requests that this
Petition be processed under Modified Procedure; i.e., by written submissions rather than by
hearing. See Commission Rule of Procedure 201, et seq.

to this proceeding should be sent to:
