4 3. Purpose of Today s Meeting Per SRP s OATT, SRP conducts the 4 th quarter public planning meeting to: A) Review its current transmission study plan provide an opportunity for transmission customers to update their loads, resources and other data review any stakeholder proposals previously submitted to SRP for study plan alternatives B) Present a draft of its Ten Year Plan for the following calendar year 4

5 3. Purpose of Today s Meeting Continued C) Provide updates on the generation study requests D) Provide updates on the transmission study requests E) Provide updates on the economic study requests F) Invite stakeholders to submit additional study proposals 5

6 3.A. SRP s Study Plan SRP has two distinct, but related, transmission study plans NERC Compliance SRP s budgetary planning The difference between the two plans: NERC Compliance studies based on new TPL Standard: 2 seasons/scenarios, 3 discrete years (near and long term) SRP s annual planning: 1 season, 10 consecutive years (first 6 years are for budget, remaining 4 for compliance purposes) The similarities between the two plans: Similar load forecasts, demand response They are reliability studies 6

7 3.A NERC Compliance Study Methodology Coordinated Base Cases (Seed Cases) 2018 AZ coordinated case used to build AZ coordinated case used to build AZ coordinated case used to build 2026 The intermediate cases are APS/SRP coordinated 69kV transmission models incorporated Most up-to-date forecasts for peak summer loads 7

23 3.C. 3.E. Transmission Planning Study Process SRP evaluates plan submittals or alternatives according to the following flowchart. Exhibit 1 SRP Attachment K * Transmission Planning Process Economic What Type of Study? 1 Reliability Regional Transmission Provider Evaluation High priority Local 2 Transmission Provider Economic Study Not high priority Does Transmission Provider s system meet NERC/WECC criteria? 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. * Note WECC organizational changes discontinued TEPPC 12/12/2016 APS/SRP Stakeholder Meeting for Transmission Planning 23
