OREGON
Case No. LC 81
Order No. 24-156 (5/31/2024)
This order memorializes our decision, made and effective at our February 22, 2024,
special public meeting, concerning the 2023 Integrated Resource Plan(IRP) for Avista
Corporation, dba Avista Utilities. Through this IRP process, we reviewed Avista's
longterm plan for a least-cost, least-risk portfolio of resources to serve customer energy
needs and satisfy state policy requirements, as well as a corresponding series of
implementing actions that Avista intends to take in the next two to four years (the "action
plan"). We acknowledge Avista's near term action plan, as revised on February 15, 2024.
As revised, Avista's proposed action plan includes primarily energy efficiency actions; in
response to the Oregon Court of Appeals' invalidation of the Department of
Environmental Quality(DEQ) Climate Protection Program(CPP), Avista removed action
items related to the purchase of Community Climate Investments (CCIs) and renewable
natural gas (RNG) for compliance with the CPP. We also adopt some but not all of the
recommendations for future Avista plans from Staff of the Public Utility Commission of
Oregon, attached to this order as Appendix A, and including requirements for non-pipes
alternatives, alternative resource portfolios, and load forecasting.
We do not, however, acknowledge Avista's long-term plan and preferred resource
portfolio. We are persuaded by Staff s explanation of the significance of the absence of
alternative portfolios, an error in climate modeling affecting the load forecast, and
unrealistic assumptions about costly decarbonized fuels.
