Planning Reserve Margin Proposal - PRC Workplan Task Force 2
Closed
Jan 21, 2026 to Feb 18, 2026
Proposal to reevaluate the FS Planning Reserve Margin (FSPRM) and FS Capacity Requirement – including timing and modeling methodology – for the Western Resource Adequacy Program (WRAP)
The Program Review Committee’s (PRC) 2025 Workplan consolidated Concepts 2024-CRF-002 and 2024-CRF-017 into the PRM Task Force. The charge was to reevaluate the FS Planning Reserve Margin (FSPRM) and FS Capacity Requirement – including timing and modeling methodology – for the Western Resource Adequacy Program (WRAP), and to develop a Proposal for stakeholder review in accordance with BPM 302 Program Review Committee Proposal Development and Consideration.
The Task Force discussed the issues in the submitted Change Request Forms (CRF) and is proposing changes to the WRAP, including:
Adjusting timing of the FSPRM calculation (LOLE Study) to ensure FSPRMs for Binding Seasons are approved by the Board of Directors five (5) years ahead of the FS Deadline of that Binding Season,
Modifying the duration of the binding Winter Season to better align observed risk with season duration, and
Updating the methodology of the LOLE study to limit month-to-month variability.
Additionally, the Proposal includes how the WRAP will transition from the current state to the proposed state.
