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 REDACTED STAFF COMMENTS l JULY 6,2021 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. REDACTED STAFF COMMENTS 2 JULY 6,2021 Figure No.1.2021 Platts Forecast vs.October 2020 Forecasts from Three Utilities 2021 Platts Forecast vs.October 2020 Forecasts Used by Idaho Power,Avista and Rocky Mountain Power 2 1 0 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032 2033 2034 2035 2036 -Idaho Power --Avista Rocky Mountain Power 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.

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.

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.
