4 3. Purpose of Today s meeting Per APS s OATT, APS conducts the 2 nd quarter public planning meeting to A) review its current transmission study plan B) provide an opportunity for transmission customers to update their loads, resources and other data that were submitted by September 1 C) provide an opportunity for stakeholder input on any aspect of the study plan D) review any stakeholder proposals previously submitted to APS for study plan alternatives E) invite submittal of additional stakeholder study plan proposals for review and discussion F) provide updates on APS s planned transmission projects 4

5 3.A. APS s Study Plan APS has two distinct, but related, transmission study processes NERC Compliance APS s Annual Planning The difference between the two processes: NERC Compliance: Minimum 2 seasons, 3 discrete years (near and long term); all cases examine P0-P7 (formerly Category A D) APS s annual planning: 1 season, 10 consecutive years; N-0 and N-1 5

6 3.A. NERC Compliance Results? 2017 Results? APS is fully compliant with NERC Transmission Planning Standards 2018 Progress? SWAT case building complete SWAT DYD files complete 6

7 3.A Ten-Year Plan Methodology Coordinated Base Cases 2020HS AZ coordinated case used to build heavy summer HS AZ coordinated case used to build heavy summer HS AZ coordinated case The intermediate cases are APS/SRP coordinated 69kV transmission models incorporated Most up-to-date forecasts for peak summer loads N-0 and N-1 analysis conducted for all ten years Note: AZ coordinated cases also included IID 7

8 3.A NERC Compliance Study Methodology NERC Compliance Studies Cases 2020 peak case off-peak case 2023 peak 2028 peak case Data from various IRP filings are incorporated (ex. generator retirements are accounted for) Following analyses are conducted: Thermal and voltage Short-Circuit Transient Stability 8

No Transmission Provider determines facilities needed with Stakeholder input Study results documented in a report and reviewed by Customer and Transmission Provider Yes TEPPC evaluates with Stakeholder input Customer Choice of Study at Customer s expense Does Transmission Provider s system meet local reliability criteria? No Transmission Provider determines facilities needed with Stakeholder input TEPPC determines high priority, performs study TEPPC determines not high priority Yes Transmission Provider coordinates with Sub- Regional Planning Group 1. Generator Interconnection Request studies are performed pursuant to the Large Generator Interconnection Procedure contained in the Transmission Provider s Open Access Transmission Tariff (OATT). Transmission Service Requests are also performed pursuant to OATT procedures. 2. All requests for economic planning studies received by the Transmission Provider are forwarded to TEPPC for inclusion in the TEPPC Master List. TEPPC will evaluate only those requests that have regional impacts. 12
