)ORDER NO.33925
On October 13,2017,Idaho Power Company filed its annual update to certain
components of its avoided cost rate calculation for qualifying facilities (QF)under the Public
Utility Regulatory Policies Act of 1978 (PURPA).Specifically,Idaho Power updated the load
forecast,natural gas forecast,and contract information components that it uses to calculate
avoided cost rates under the incremental cost Integrated Resource Plan (IRP)method,and asks
the Commission to accept the updated information for filing.Application at 1.With this Order,
the Commission provides notice of the Company's Application and notice that interested persons
may file written comments about the Application.
BACKGROUND
Under PURPA,electric utilities must purchase electric energy from QFs at rates
approved by the applicable state agency--in Idaho,this Commission.16 U.S.C.§824a-3;Idaho
Power Co.v.Idaho PUC,155 Idaho 780,780,316 P.3d 1278,1287 (2013).The purchase or
"avoided cost"rate shall not exceed the '"incremental cost'to the purchasing utility of power
which,but for the purchase of power from the QF,such utility would either generate itself or
purchase from another source."Order No.32697 at 7,citing Rosebud Enterprises v.Idaho PUC,
128 Idaho 624,917 P.2d 781 (1996);18 C.F.R.§292.101(b)(6)(defining "avoided cost").
The Commission has established two methods of calculating avoided cost,depending on
the size of the QF project:(1)the surrogate avoided resource (SAR)method,and (2)the IRP
method.See Order No.32697 at 7-8.The Commission uses the SAR method to establish what
are commonly referred to as "published"avoided cost rates.Id Published rates are available for
wind and solar QFs!with a design capacity of up to 100 kilowatts (kW),and for QFs of all other
i See Order No.33785 (regarding battery storage facilities).

resource types with a design capacity of up to 10 average megawatts (aMW).On the other hand,
if a QF's design capacity is above the published rate eligibilitycaps,the utility must use the IRP
method to negotiate a project-specific avoided cost rate with the QF.Id.at 2;Order No.32176.
The IRP method accounts for "many different variables and produces a[n avoided cost]result
based on each individual utility's need for energy."Order No.32697 at 17.The IRP method's
variables are at issue here.
With respect to the IRP method,the Commission requires utilities to update fuel price
forecasts and load forecasts each year on October 15.Order No.32802 at 3.All other IRP
method variables and assumptions remain fixed between the biennial IRP filings.Order No.
32697 at 22.The Commission expects the utility's load and resource balance to account for
long-term contract commitments,and PURPA contracts that have terminated or expired.Id.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that,with this Application,Idaho Power updates its
load forecast,natural gas forecast,and contract information.The Company explains that the
information has been incorporated into its IRP avoided cost model and that it will use the model

in its 2017 IRP process.Id.In the 2016 update,Idaho Power used the EIA Reference Case
forecast for Natural Gas Henry Hub Spot Price.Id The Company explains that the 2017
forecast shows "a decrease in the average annual natural gas prices over the remaining period"
