FROM: MICHAEL DUVAL
DEPUTY ATTORNEY GENERAL

DATE: DECEMBER 12, 2023

SUBJECT: IN THE MATTER OF ROCKY MOUNTAIN POWER’S APPLICATION
REQUESTING AUTHORIZATION TO UPDATE THE WIND AND SOLAR
INTEGRATION RATE FOR SMALL POWER GENERATION
QUALIFYING FACILITIES; CASE NO. PAC-E-23-24.

On November 29, 2023, Rocky Mountain Power, a division of PacifiCorp (“Company”)
applied to Commission for authority to increase the wind and solar integration rate applicable to
new power purchase agreements (“PPA”) between the Company and wind and solar qualifying
facilities (“QFs”). The Company requested that its Application be processed via modified
procedure.
THE APPLICATION
The Company requested authorization to decrease the wind integration rate from $1.25 to
$1.18 per megawatt-hour (“MWh”) for wind-powered QFs. The Company also requested
authorization to increase the solar integration rate from $0.96 to $1.40 per MWh for solar-powered
QFs. The Company stated the change is due to the integration costs of wind and solar power
compared to published avoided cost rates. However, the Company noted that an exception to this
default practice of determining the price occurs when QF delivers energy to the Company on a
firm hourly schedule as specified in a PPA.
STAFF RECOMMENDATION
Staff recommends the Commission issue a Notice of Application and set a 21-day
intervention deadline.
