RE: Case No. GNR-E-23-02 – Staff’s Application to Update Inputs to the “Surrogate Avoided
Resource” Method Avoided Cost Rates

Avista Corporation dba Avista Utilities (Avista or Company) received the Notice of Application
Order No. 35758 from the Idaho Public Utilities Commission (IPUC) dated April 28, 2023
notifying the Company of Commission Staff’s application for an order updating inputs to the
surrogate avoided resource method (“SAR Method”) model, making administrative changes to the
SAR Method model, and approving the SAR Method avoided cost rates for eligible qualifying
facilities (“QFs”) and opportunity to file written comments on this matter. On May 2, 2023, Avista
filed a letter of agreement but mistakenly referenced the wrong avoided cost filing. For
clarification, the Company has reviewed the new published avoided cost rates as described in
Staff’s application and agrees that the rates are correct.

Please direct any questions on this matter to Chris Drake at [phone] or myself at (509) 495-
2782.

Sincerely,

/s/Shawn Bonfield
