RE:CASE NO.PAC-E-22-14
IN THE MATTER OF ROCKY MOUNTAIN POWER'S APPLICATION
FOR APPROVAL OF A CAPACITY DEFICIENCY PERIOD TO BE USED
FOR AVOIDED COST CALCULATIONS
BACKGROUND
On June 29,2023,the Idaho Public Utilities Commission ("Commission")issued Order
No.35834 in Case No.PAC-E-22-14,directing Rocky Mountain Power ("Company"),a division
of PacifiCorp,to submit a compliance filingwithin 21 days to address Load and Resource
Balance ("L&R")issues listed in the Order.
On July 12,2023,the Company requested a waiver of the compliance filing.The
Company also proposed to file its capacity deficiency case for the 2023 Integrated Resource Plan
("IRP")after the 2023 IRP is acknowledged,addressing the compliance filing items in that
application.
STAFF REVIEW
Staff believes it is reasonable for the Company to file its capacity deficiency case for the
2023 IRP after the acknowledgement of the 2023 IRP.Order No.35810 changed the filing time
of capacity deficiency cases from "after the acknowledgement of each IRP"to "within 30 days
of filing each IRP."However,when Order No.35810 was issued on June 8,2023,more than 30
days had passed since the filing of the 2023 IRP.Therefore,it is reasonable for the Company to
use the original filing time.Staff also believes it is reasonable to address the compliance filing

items in that case so that the Commission's guidance is followed while the latest data from the
2023 IRP are used.
STAFF RECOMMENDATION
Staff recommends that the Commission grant the waiver of the compliance filing and
direct the Company to file its next capacity deficiency case after the acknowledgementof the
2023 IRP,incorporating the compliance filing items in its application.
COMMISSION DECISION
Does the Commission wish to grant the waiver of the compliance filing and direct the
Company to file its capacity deficiency case after the acknowledgement of the 2023 IRP,
incorporating the compliance filing items in its application?
