C. This IRP scenario was used to create many of the assumptions and forecasts included in the 2021 SO Report, such as the projected sustaining capital expenditures and steam fleet retirement schedule. NS Power acknowledged in its 2021 fili...

AI summary The 2021 System Outlook (SO) Report relied on the 2020 IRP Scenario 2.0C, but the Consumer Advocate and Small Business Advocate questioned its appropriateness. NS Power shifted to Scenario 3.1C in the 2022 SO Report, claiming it better reflects current policy and load conditions. The Board emphasized incorporating post-2021 legal changes into future planning.
