STAFF OF the Idaho Public Utilities Commission,by and through its Attorneyof record,
John R.Hammond,Jr.,Deputy Attorney General,submits the followingcomments.
BACKGROUND
On May 13,2021,Idaho Power Company (the "Company")applied to update the natural
gas forecast that is utilized in the Incremental Cost IntegratedResource Plan ("ICIRP")avoided
cost method.Avoided cost rates determined by the ICIRP method are available to qualifying
facilities ("QFs")able to generate above the resource-specific project eligibilitycap for published
avoided cost rates under Idaho's implementation of the Public Utility Regulatory Policies Act of
1978 ("PURPA").
The annual update of the gas and load forecast for the ICIRP method in 2020 in IPC-E-20-
35 was based upon the gas forecast used in the 2017 IntegratedResource Plan ("IRP"),which was
the U.S.Energy Information Administration's ("EIA")Henry Hub High Oil and Gas Resource

and Technology forecast.Later,the Second Amended 2019 IRP was acknowledgedon March 16,
2021,in Order No.34959,used a new gas forecast provided to the Company by S&P Global
Platts ("Platts").However,the Second Amended 2019 IRP used the 2018 Platts forecast.The
Company in the Application of this case requests the use of the most up-to-date information
available,which is the 2021 Platts forecast published March 4,2021.
The Company states the use of this forecast indicates an approximate 3%overall decrease
in the average annual natural gas forecast prices over the remaining period in comparison to the
2018 natural gas price forecast from the acknowledged 2019 IRP.The Company represents that
although the updated Platts'natural gas forecast shows a slight decrease overall,it contains yearly
increases in 2021-2023 and 2039-2040.
STAFF ANALYSIS
Staff believes that the 2021 Platts natural gas forecast that the Company is proposing to
use in this case for determining avoided cost rates under the ICIRP method in future PURPA
contracts is reasonable.Staff's conclusion is based on its analysis of Platt's forecast compared to
other Idaho utility natural gas forecasts,considering short-term market fundamentals occurring in
the market,and an assessment of Platts as the source of the forecast compared to the previous EIA
source used by the Company.After considering these reasons,Staff recommends that the
Commission approve the use of the 2021 Platts forecast for determining avoided costs to be used
in the ICIRP avoided cost method.
Comparison of Gas Forecasts Used by Three Utilities
Staff has reviewed the 2021 Platts forecast data and believes the forecast is reasonable
compared to the 2020 forecasts from the three Idaho utilities.As can be seen in Figure No.1
below,the 2021 Platts forecast is like the October 2020 forecasts used by Idaho Power,Avista,
and Rocky Mountain Power over the long run.However,the 2021 Platts forecast differs from
these 2020 forecasts by projecting higher natural gas prices in the first few years of the forecast
time horizon.Staff believes that the higher natural gas prices in the short-term coincide with
market conditions that have changed since the three utilities'forecasts were published in October
of2020.

The increases in natural gas prices in the short term are driven by a decrease in supply of
and an increase in demand for natural gas.Multiplesourcesi have shown that the reduced gas
supply is caused primarily by recent historic low oil and natural gas prices.Because of low
prices,producers have lowered the number of rigs deployed for production,reducing both direct
and associated natural gas production.According to the same sources,factors increasing the
demand of natural gas include competition for natural gas due to the demand for LNG exports and
increased natural gas-fired electricity production.
For purposes of this filing,which is to determine the natural gas forecast used to in the
ICIRP method,the near-term forecast is most critical.This is because the contracts that use the
ICIRP method for determining avoidedcost rates are limited to two-year term lengths.
Because the overall Platts forecast is comparable to prior utility forecasts and includes
modifications based on current and near-term market conditions,Staff believes that the 2021
Platts forecast is reasonable to be used in the ICIRP avoided cost method.

REDACTED STAFF COMMENTS 3 JULY 6,2021
Platts Forecast vs.EIA Forecast
The Company changed the source of its natural gas forecast from EIA to Platts,both in the
2019 IRP and in this filing.In Order No.33957,the Commission stated,"We further find it
appropriate,going forward,that if the Company changes its EIA base forecast,it should provide a
reasonable basis for such change."Staff supports the Company's use of the Platts forecast based
on justificationssummarized below.
First,the Company provided a comparison that was conducted as part of the 2019 IRP of
market forward prices and the 2018 EIA Reference Case and the 2018 EIA High Oil and Gas
Resource and Technology Case forecasts in Response to Staff s Production Request No.1.
Because of differences between forward prices and EIA's forecasts shown in Figure No.2,the
Company started exploring other third-party forecasts (shown in Figure No.3)and chose the
Platts forecast for the 2019 IRP,because "Platt's forecast appeared to more closely align with the
first several years of the forward market and then was in range with the others by 2026."See
Response to Staff's Production Request No.1.

Second,the Company stated,"Because the first few years of forwards are traded actively,
Idaho Power felt that what the EIA was forecasting was not accurate,at least for those first few
years."Id.Staff agrees.The only EIA forecast that reasonably aligns to forward market prices is
EIA's High Oil and Gas Case forecast,which the Company chose to use in their 2017 IRP (See
2017 IRP,p.84).However,Staff believes that the input assumptions EIA uses to develop their
High Oil and Gas Case forecast are not realistic and it would be improper to use a forecast with
unrealistic input assumptions in order to obtain a reasonable result.2
2 In the High Oil and Gas Resource and Technology case,the estimated ultimate recovery per well is assumed to be
50%higher than in the Reference case for tight oil,tight gas,and shale gas in the Lower 48 States;undiscovered
resources in Alaska;offshore Lower 48 states.Rates of technological improvement that reduce costs and increase
productivityin the United States are also 50%higher than in the Reference case.See Page 6 of Annual Energy
Outlook 2021:Case Descriptions at https://www.eia.gov/outlooks/aeo/assumptions/pdfcase_descriptions 2021.pdf
REDACTED STAFF COMMENTS 5 JULY 6,2021
Impacts of the New Forecast
For the next five years from 2021 through 2025,the 2021 Platts forecast is
higher than the 2020 EIA forecast currentlyused in the ICIRP avoided cost method,which will
likely result in higher avoided cost rates.The forecast will be updated in October,using the latest
information available at that time.
STAFF RECOMMENDATION
Based on its analysis,Staff recommends approval of the 2021 Platts forecast contained in
Confidential Attachment No.1 of the Application to be used in the ICIRP method.
Respectfully submitted this day of July 2021.
