SUBJECT: UPDATE TO PUBLISHED AVOIDED COST RATES TO REFLECT AN
UPDATED NATURAL GAS PRICE FORECAST OF THE U.S. ENERGY
INFORMATION ADMINISTRATION (EIA), CASE NOS. AVU-E-15-04,
IPC-E-15-16, PAC-E-15-07

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 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 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.
The Annual Energy Outlook 2015 was released on April 14,2015.A copy of the
relevant natural gas price forecast is attached.
STAFF REVIEW
Commission Staff has recomputed avoided cost rates for Idaho Power,Avista,and
PacifiCorp,using EIA’s most recent natural gas price forecast.Staff provided Idaho Power,
Avista,and PacifiCorp with worksheets on May 7,2015,for review and comment,showing the
computation of the updated avoided cost rates.A copy of the rates computed by Staff for all three
utilities is attached.Due to the higher near-term natural gas price forecast,the new avoided cost
rates for the year of 2015 have increased approximately 2 to 4%from the previously published
rates for the same year,depending on the generation type.
STAFF RECOMMENDATION
Staff recommends that the attached avoided cost rates for Idaho Power,Avista,and
PacifiCorp be approved with an effective date of June 1,2015.
COMMISSION DECISION
Presented for Commission approval are the updated published avoided cost rates for
Idaho Power,Avista,and PacifiCorp,which have incorporated the natural gas price forecast
published in the release of EIA’s Annual Energy Outlook 2015.The calculation of the fuel cost
adjustment to published avoided cost rates is arithmetic.Does the Commission wish to approve
the changes in rates effective June 1,2015?
