Description Of Issue
The calculation of monthly PRMs should be evaluated to determine whether they are achieving the intended goals and accurately modeling the mitigation of loss of load probability, while also achieving stability and mitigating volatility. Monthly PRMs provide beneficial granularity and flexibility but have exhibited some concerning volatility month-to-month. Idaho Power has seen some shoulder season months with load + PRM total obligation significantly exceeding Idaho Power’s own extreme weather load forecasts as well as its own long-term planning load forecasts + Idaho Power’s PRMs. Idaho Power is asking for a comprehensive effort to evaluate, review, and consider alternatives to the calculation of the monthly PRMs.
Idaho Power also supports the desire for stability that is reflected in change request 2024-CRF-002.
