RE: IRP Docket No. E-99999A-25-0058, Response to Staff’s June 23, 2026 Memo
 
Chairman and Commissioners,
 
The Arizona Solar Energy Industries Association ("AriSEIA") supports the Utilities Division Staff's recommendation to amend Decision No. 80699 to extend the Integrated Resource Plan ("IRP") filing schedule and establish a February 10, 2027 deadline for stakeholder comments and stakeholder deliverables.
 
AriSEIA also appreciates Staff's recommendation that the revised IRP schedule apply uniformly to all Commission-regulated electric utilities required to file IRPs. A consistent statewide schedule promotes administrative efficiency, reduces unnecessary scheduling conflicts, and allows stakeholders that participate across multiple IRP proceedings to more effectively allocate their resources.
 
AriSEIA respectfully requests one clarification to the proposed order. While Staff recommends that all Commission-regulated electric utilities follow the timeline set forth in Table 2, Table 2 itself is drafted using APS-specific references, including "APS Files IRP" and "APS Response to Stakeholder Comments." As a result, it is not clear that the February 10, 2027 deadlines for stakeholder comments and stakeholder deliverables apply to all Commission-regulated electric utilities required to file IRPs. Because stakeholders submit comments to each utility's IRP, AriSEIA respectfully requests that the Commission expressly clarify that stakeholders may submit comments and stakeholder deliverables for each Commission-regulated electric utility's IRP on or before February 10, 2027.
 
Accordingly, AriSEIA respectfully requests that Ordering Paragraph 1 be revised as follows:
 
IT IS THEREFORE ORDERED that Decision No. 80699 is hereby amended to adopt the Integrated Resource Plan timeline for all Commission-regulated electric utilities that are required to file an Integrated Resource Plan as detailed in Finding of Fact No. 6, Table 2. The February 10, 2027 deadlines for stakeholder comments and stakeholder deliverables shall apply to each Commission-regulated electric utility required to file an Integrated Resource Plan.
 
Subject to that clarification, AriSEIA supports Staff's recommendation.
 
Respectfully,
/s/ Autumn T. Johnson
Executive Director
