Case No. AVU-E-24-01
Order No. 36314 (9/6/2024)
On August 16, 2024, Staff of the Idaho Public Utilities Commission("Staff')applied for an
order(1)updating Surrogate Avoided Resource Model ("SAR Model") inputs; (2)making
administrative changes to the SAR Model; and(3) approving SAR-based avoided cost rates
included with the Application. Staff asserts that updating the SAR Model inputs is necessary
because the U.S. Energy Information Administration("EIA") did not publish an Annual
Energy Outlook in 2024,which previously served as the basis for annual SAR Model
updates. Staff proposes using different inputs to update the SAR Model until a new EIA
forecast becomes available. Staff requested this matter be processed via Modified Procedure.
The Commission now issues this Notice of Application, Notice of Intervention deadline, and
Notice of Modified Procedure and sets deadlines by which interested persons may intervene.
