FROM:YAO YIN

DATE:MAY 26,2017
SUBJECT:UPDATE TO PUBLISHED AVOIDED COST RATES TO REFLECT AN
UPDATED NATURAL GAS PRICE FORECAST OF THE U.S.ENERGY
INFORMATION ADMINISTRATION,CASE NOS.AVU-E-17-02,IPC-E-17-
07,PAC-E-17-05
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 calculating the avoided cost rate at which PURPA qualifying cogeneration and
small power production facilities (QFs)are paid by Idaho Power,Avista,and PacifiCorp.
Avoided cost rates are the purchase price paid to QFs for purchases of QF capacity and energy.
The release of a new natural gas price forecast by the U.S.Energy Information Administration
(EIA)triggered an updated calculation of avoided cost rates.
UPDATED NATURAL GAS PRICE FORECAST
One of the key input variables in the computation of avoided cost rates in the SAR
methodology is a 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 published in EIA’s Annual Energy Outlook serves as the basis for
computing avoided cost rates.In Order No.32697,the Commission also found that the final
release of Annual Energy Outlook automatically triggers a recalculation of the published avoided
cost rates.In Order No.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.
DECISION MEMORANDUM 1
The Annual Energy Outlook 2017 was released on January 5,2017.A copy of the
relevant natural gas price forecast is attached.
STAFF’S ANNUAL UPDATE
Commission Staff has recomputed avoided cost rates for PacifiCorp,Avista,and Idaho
Power,using the EIA’s most recent natural gas price forecast.The new avoided cost rates,if
approved,will increase approximately 1%to 6%from current published rates,depending on the
generation type.Staff computed the rates for all three utilities and attached a copy to this
Memorandum.Staff provided Idaho Power,Avista,and PacifiCorp with worksheets showing the
computation of the updated avoided cost rates on May 16,2017,for review and comment.
UTILITIES’RESPONSES
In its response letter,Avista identified an issue with capacity payment calculations for
replacement contracts that Staff believes is outside the scope of this case.1 However,both Avista
and PacifiCorp acknowledged that the rates as presented are correct.
Idaho Power objected to use of the ETA’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
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 is used in Idaho Power’s 2017 Integrated Resource
Planning process and Incremental Cost IRP methodology.
STAFF RECOMMENDATION
Staff observes that the EIA’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.Thus there is no precedent for how to process
an objection to Staffs annual update to the published avoided cost rates reflected in updated
natural gas price forecasts.Staff believes its proposed updated rates should not be delayed,but
that it is appropriate to give Idaho Power’s objection and proposal due consideration.
Staff recommends that its proposed updated rates be approved,effective June 1,2017
(per Order No.32697),and that the Commission accept Idaho Power’s objection as an application
Staff believes the issue only affects Avista,as a winter peaking utility,not the other two utilities which are summer
peaking.Therefore,Staff will discuss this concern with Avista separately.If Avista’s concern remains after such
discussions,Staff believes it appropriate for Avista to file a separate application to address the issue.
DECISION MEMORANDUM 2
in a generic proceeding (as to all three utilities)to revise Staff’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 full impact of Idaho Power’s proposal.Staff
recommends that the Commission issue a Notice of Application and Notice of Modified Procedure
setting a 21-day comment period and a 14-day all-party reply.
Counsel for Idaho Power has indicated Staffs proposal is reasonable,and Idaho Power
does not object to processing its objection as Staff recommends.
COMMISSION DECISION
Does the Commission wish to accept Staffs updated published avoided cost rates for
Idaho Power,Avista,and PacifiCorp,effective June 1,2017?
Does the Commission wish to accept Idaho Power’s objection as an application for a
generic proceeding and issue a Notice of Application and Notice of Modified Procedure with a 21-
day comment period and a 14-day all-party reply period?
