Consistent with AWEC’s response to Question 1, consideration of changes necessary to address the unique nature of non-conforming loads is necessary well in advance of the March 31, 2027 Forward Showing Deadline because resource acquisitions will need to be made well in advance of this deadline in order for a Participant to meet Forward Showing obligations. Over procurement of capacity and/or the failure to recognize the resource adequacy benefits that some non-conforming loads offer will serve to unnecessarily increase costs to retail consumers and may chill retail customer investment in, and reliance on, co-located and/or behind-the-meter resources. Because utilities and their end-use consumers are making resource procurement decisions now, time is of the essence to address WRAP’s treatment of non-conforming loads.

APS believes the following concepts would provide the most value in advance of the March 31, 2027 Forward Showing deadline for the first binding Season (Winter 2027–2028):
• Day-Ahead Market Optimization
• Effective Load Carrying Capability (ELCC) approach
• Forward Showing Deficiency Deferral Resolution
• Participant-to-Participant Joint Capacity Accreditation Forms (JCAFs)
APS supports the draft Workplan as presented under Schedule III, which appropriately positions each of these items for completion, clarification or meaningful progress ahead of the Forward Showing deadline. Advancing these concepts on the proposed timeline will materially improve participant certainty and support successful execution of WRAP during the first binding period.
