On May 5, 2026, Commission Staff ("Staff') applied to the Idaho Public Utilities
Commission ("Commission") requesting the Commission issue an order updating inputs to the
Surrogate Avoided Resource ("SAR") Model of Rocky Mountain Power, a division of PacifiCorp
("Company"), approving the resulting SAR-based avoided cost rates, and establishing a new
processing timeline for the annual update ("Application").
The Commission now issues this Notice of Application and Notice of Modified Procedure
establishing written comment deadlines.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED that Staff requested that the Commission approve the
proposed annual update to SAR-based avoided cost rates for qualifying facilities under the Public
Utility Regulatory Policies Act of 1978 based on inputs to the SAR Model using the natural gas
price forecast from the Mountain Region Reference Case in the United States Energy Information
Administration("EIA") Annual Energy Outlook. Application at 1-2.
YOU ARE FURTHER NOTIFIED that the EIA published its Annual Energy Outlook on
April 8,2026.Id. at 2. Staff states that it used the published natural gas price forecast through 2050
to update the SAR Model.Id.
YOU ARE FURTHER NOTIFIED that because the SAR Model is designed to calculate
30 years of avoided cost rates while the Annual Energy Outlook currently forecasts only 25 years,
Staff s proposed SAR Model extrapolates the EIA's data to create values for the additional years.
