MODIFIED PROCEDURE
ORDER NO. 36153
On April 1, 2024, Rocky Mountain Power, a division of PacifiCorp ("Company"),
applied for Commission authorization to adjust its rates under the Energy Cost Adjustment
Mechanism(`SCAM"). Specifically,the Company seeks approval of approximately$62.4 million
in ECAM deferral for the period of January 1, 2023, through December 31, 2023, with a 10.5
percent increase to Electric Service Schedule No. 94, Energy Cost Adjustment. The monthly bill
for a typical residential customer using 783 kilowatt-hours of electricity per month would increase
by$7.39. The Company requests its proposed adjustment be processed by Modified Procedure and
become effective on June 1, 2024.
The Commission now issues this Notice of Application and Notice of Modified
Procedure, establishing public comment and Company reply deadlines.
BACKGROUND
The ECAM allows the Company to increase or decrease its rates each year to reflect
changes in the Company's power supply costs. These costs vary by year with changes in the
Company's fuel (gas and coal) costs, surplus power sales, power purchases, and associated
transmission costs. Each month, the Company tracks the difference between the actual net power
costs ("NPC") it incurred to serve customers, and the embedded (or base) NPC it collected from
customers through base rates. The Company defers the difference between actual NPC and base
NPC into a balancing account for treatment at the end of the yearly deferral period. At that time,
the ECAM allows the Company to credit or collect the difference between actual NPC and base
NPC through a decrease or increase in customer rates. Neither the Company nor its shareholders
will receive any financial return because of this filing.
