BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF THE ANNUAL UPDATE )
TO PUBLISHED AVOIDED COST RATES )CASE NOS.AVU-E-18-04
BASED ON THE UPDATED NATURAL GAS )IPC-E-18-05
PRICE FORECAST OF THE U.S.ENERGY )PAC-E-18-02
INFORMATION ADMINISTRATION (EIA))
)ORDER NO.34062
Pursuant to the Public Utility Regulatory Policies Act of 1978 (PURPA)and the
implementing regulations of the Federal Energy Regulatory Commission (FERC),the Idaho
Public Utilities Commission (Commission)has approved a Surrogate Avoided Resource (SAR)
methodology for calculation of the published avoided cost rates at which PURPA qualifying
cogeneration and small power production facilities (QFs)are paid by Avista,Idaho Power and
PacifiCorp.Avoided cost rates are the purchase price paid to QFs for purchases of QF capacity
and energy.The release of the Annual Energy Outlook by the U.S.Energy Information
Administration (EIA)triggered an updated calculation of SAR avoided cost rates.
EIA UPDATE TO THE NATURAL GAS PRICE FORECAST
The surrogate resource is based on natural gas plant pricing,therefore one of the key
input variables in the computation of published avoided cost rates is the long-term natural gas
price forecast.In accordance with the methodology approved in Order No.32697,and
subsequent orders,the "reference case"natural gas price forecast for the Mountain Region's
Electric Power sector included in EIA's Annual Energy Outlook serves as the basis for
computing published avoided cost rates.In Order No.32697,this Commission stated that each
year the final release of the Annual Energy Outlook should automatically trigger a re-calculation
of the published avoided cost rates.In Order 32802,the Commission clarified that an update
should occur on June 1 or within 30 days of the final release of the Annual Energy Outlook,
whichever is later.This clarification was to accommodate the possibility that the final release of
EIA data does not occur in time to meet the June 1 effective date.
UPDATED PUBLISHED AVOIDED COST RATES
Commission Staff recomputed published avoided cost rates for Idaho Power,Avista,
and PacifiCorp using EIA's most recent annual natural gas price forecast.Staff provided Avista,
ORDER NO.34062 1
Idaho Power,and PacifiCorp with worksheets on April 5,2018,for review and comment,
showing the computation of the updated avoided cost rates.
Both Avista and PacifiCorp acknowledged that the rates computed by Staff as
presented are correct.Idaho Power concurred that the calculations provided by Staff are
consistent with the SAR methodology approved in Commission Orders Nos.32697 and 32802.
Idaho Power Response Letter at 1.However,it expressed concerns with the use of the reference
case natural gas price forecast for the Mountain Region's Electric Power sector included in the
EIA's Annual Energy Outlook.Id.
Idaho Power argued that while Commission Order No.32697 generically requires the
use of the EIA forecasts in the SAR methodology,it does not specify which data series must be
used.Id.Idaho Power disagreed with the use of the Mountain Region sector forecast,claiming
that it is not a representative forecast for natural gas prices because it represents pricing that is
higher than historical and expected natural gas transactions specific to Idaho Power.Id.
More specifically,Idaho Power claimed that the use of the Mountain Region sector
forecast unreasonablyinflated the SAR avoided cost prices and its customers should not have to
pay inflated costs.Id.Instead,Idaho Power suggested Commission Staff use the EIA's natural
gas spot price at Henry Hub:High Oil and Gas Resource and Technology forecast,adjusted for
Sumas and Idaho City Gate,which was also utilized in Idaho Power's 2017 Integrated Resource
Planning process and Incremental Cost IRP methodology.Id.'
Idaho Power stated that it undertook a comparison between Staff's proposed avoided
cost rates and its suggested methodology and found that "[w]hen the Natural Gas Spot Price at
Henry Hub forecast is applied as the basis in the SAR methodology,the approximate decrease in
20-year levelized avoided cost prices across all resource types,assuming an online year of 2018,
is $10.99 per megawattshour."Id.at 1-2.
Idaho Power further stated that it is experiencing increased development of new
PURPA QFs that are eligible for published avoided cost rates over the next several years.Id.at
2.These QFs must enter into new or replacement energy sales agreements where,according to
Idaho Power,use of the Mountain Region natural gas price forecast results in higher avoided
costs.Id.In order to rectify this,Idaho Power suggested that each applicable Idaho utility
*Staff disagreed with the Company changing its forecast away from EIA's Mountain Region sector forecast to
EIA's "High Oil and Gas Resource and Technology Case"forecast in the 2017 IRP.See Comments of the
Commission Staff in Case No.IPC-E-17-11.
)R l)ER NO.34062 2
should utilize its own natural gas forecast stream in terms of computations made under the SAR
methodology.Id.
Staff recommended that its proposed updated rates be approved,effective June 1,
2018 (per Order No.32697),but that the Commission find that Idaho Power's suggestion may be
raised in a generic docket,brought of its own volition,related to the revision of the
Commission's methodology for updating published avoided cost rates to reflect updated natural
gas price forecasts.In such proceeding,all electric utilities and interested parties would have the
opportunityto provide comment so the Commission can more fully understand the impact of
Idaho Power's proposal.
FINDINGS AND CONCLUSIONS
The Idaho Public Utilities Commission has jurisdiction over Avista Corporation dba
Avista Utilities,Idaho Power Company,and PacifiCorp dba Rocky Mountain Power and the
matters considered in this case pursuant to the authorityand power granted it under Title 61 of
the Idaho Code and the Public Utility Regulatory Policies Act of 1978 (PURPA).The
Commission has authority under PURPA and the implementing regulations of the Federal
Energy Regulatory Commission (FERC)to set avoided costs,to order electric utilities to enter
into fixed-term obligations for the purchase of energy from qualified facilities,and to implement
FERC rules.
Pursuant to its authority,the Commission has reviewed and considered the filings of
record.The annual update to the SAR methodology's avoided cost rates is a relatively simple
arithmetic re-calculation.We find that the accuracy of the calculations and the resulting rates
disseminated by Staff based upon EIA's most recent annual natural gas price forecast have not
been challenged.The "suggestion"made by Idaho Power concerned the particular EIA forecast
Staff used to update published avoided cost rates.We would note that,while Order No.32697
may not explicitly adopt the "reference case"natural gas price forecast for the Mountain
Region's Electric Power sector,we have explicitlyapproved its use for the past five years in our
final orders addressing the annual EIA update.See Order Nos.32817,33041,33305,33538,and
33773.It is currently the natural gas price forecast that this Commission approves for
determination of SAR avoided costs.
We acknowledge the Company's suggestion that it would like the existing SAR
methodology altered to allow each utility its own natural gas price forecast stream but find that
ORDER NO.34062 3
Idaho Power may address its suggestion in a dedicated docket in which the other utilities and any
interested parties can provide comments to fully inform the Commission about the issue.
We fmd the updated published avoided cost rates are fair,just,and reasonable.
ORDER
IT IS HEREBY ORDERED that the updates to published avoided cost rates for
Avista,Idaho Power,and PacifiCorp are approved,effective June 1,2018.
THIS IS A FINAL ORDER.Any person interested in this Order may petition for
reconsideration within twenty-one (21)days of the service date of this Order.Within seven (7)
days after any person has petitioned for reconsideration,any other person may cross-petition for
reconsideration.See Idaho Code §61-626.
DONE by Order of the Idaho Public Utilities Commission at Boise,Idaho this
day of May 2018.
