BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION
IN THE MATTER OF THE ANNUAL UPDATE )
TO PUBLISHED AVOIDED COST RATES )CASE NOS.AVU-E-17-02
BASED ON THE UPDATED NATURAL GAS )IPC-E-17-07
PRICE FORECAST OF THE U.S.ENERGY )PAC-E-17-05
INFORMATION ADMINISTRATION (EIA))
_________________________________
)ORDER NO.33773
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 (ETA)triggered an updated calculation of avoided cost rates.
EIA UPDATE TO THE NATURAL GAS PRICE FORECAST
Because the surrogate resource is based on natural gas plant pricing,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,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 ETA 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 ETA’s most recent annual natural gas price forecast.Staff provided Avista,
ORDER NO.33773 1
Idaho Power,and PacifiCorp with worksheets on May 16.2017.for review and comment.
showing the computation of the updated avoided cost rates.
In its response letter,Avista identified an issue with capacity payment calculations for
replacement contracts.’However,both Avista and PacifiCorp acknowledged that the rates as
presented are correct.
Idaho Power objected to use of the EIA’s Mountain Region natural gas forecast upon
which the updated avoided cost rates are based.Idaho Power believes that the continued use of
this forecast “results in an artificially high price that customers should not be required to pay.”
Response and Objection of Idaho Power Company at 7.Instead,Idaho Power proposed using
the ETA’s natural gas spot price at Henry Hub:High Oil and Gas Resource and Technology
forecast,adjusted for Sumas and Idaho City Gate.which is used in Idaho Power’s 2017
Integrated Resource Planning process and Incremental Cost IRP methodology.
Staff recommended that its proposed updated rates be approved,effective June 1,
2017 (per Order No.32697),but that the Commission accept Idaho Power’s objection as an
application in a generic proceeding (as to all three utilities)to revise 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
opportunity to provide comment so the Commission can more fully understand the impact of
Idaho Power’s proposal.
Staff advised that it contacted Idaho Power,and Idaho Power indicated it did not
object to Staff’s proposal for processing Idaho Power’s objection.
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 authority and 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
Staff believes the issue is outside the scope of this case as it only affects Avista,as a winter peaking utility,not the
other two utilities which are summer peaking.Staff indicated it will discuss the issue with Avista.
ORDER NO.33773
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 objection raised by Idaho Power —the only objection to Staff’s
calculations and proposed rates —concerns the particular EIA forecast Staff used to update
published avoided cost rates.We further find that the ETA’s “reference case”natural gas price
forecast for the Mountain Region’s Electric Power sector has been used to update published
avoided cost rates each year for the past four years without objection.See Order Nos.32817,
33041,33305,33538.We find the updated published avoided cost rates are fair,just,and
reasonable.
However,we find it appropriate to consider Idaho Power’s objection in a separate
matter through which the other utilities and any interested parties can provide comments to fully
inform the Commission about the issue.Idaho Power having expressed agreement to process its
objection as such,we direct the Commission Secretary to treat Idaho Power’s objection filed in
this matter as an application in a new generic case.We will issue notice of that application and
notice of a 14-day period for petitions to intervene therein.
ORDER
IT IS HEREBY ORDERED that the updates to published avoided cost rates for
Avista,Idaho Power,and PacifiCorp are approved,effective June 1,2017.
IT IS FURTHER ORDERED that the Commission Secretary shall accept Idaho
Power’s objection in this case as an application,and open a separate generic case in which the
Commission will issue notice of the application and a 14-day period for petitions to intervene
therein.
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.
