1 Public Service Company of New Mexico Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

2 2 Agenda Introduction Agenda Additions Stakeholder Process PNM 10-Year Plan Development Regional Activities Summary of Current Interconnection Study Activity Order 1000 Stakeholder Process Status Other Items Next Meeting PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

3 3 Introduction Public Stakeholder Meetings –Order 890 Objective to improve transparency –Involvement of all affected stakeholders Coordinated with WECC processes –Reliability – System performance evaluations, reliability standards and coordination. –TEPPC – Planning Policy and Economic Evaluations Formalized Stakeholder Input through WestConnect STP Agreement OATT Appendix K defines each utility’s planning process. PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

4 4 PNM Bi-Annual Meetings March Meeting –Study Plan –Solicit Stakeholder Input to Plan November –10-Year Plan Review –Solicit Stakeholder input on plan and follow-up to be included in next planning cycle Others as needed PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

5 5 PNM Study Plan Objectives Support Data Base Development for PNM and Regional Studies –2017 (2-yr), 2020 (5-yr), 2025 (10-yr) Maintain Reliability Define Transmission for Native, Network and Point-Point Customers Incorporate Plans Developed Through FERC Processes, NM IRP and Regional Planning Analysis PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

6 6 Study Scope Review transmission adequacy with network customer updates to designated network resources and load. Determine if new system improvements or adjustments to existing improvements are needed to serve expected obligations. Develop operational mitigations or system improvements to maintain system reliability and associated cost estimates and schedule. Incorporate assessments of economic congestion if applicable. PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

7 7 Methodology Powerflow Assessments –All lines in service –Single circuit or transformer contingencies –Double circuit contingencies –Breaker failure contingencies Short Circuit Analysis Stability Analysis –Dynamic Stability –Voltage Stability PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

8 8 Key Assumptions Load forecast –Slow growth –Effects of energy efficiency, demand response and load side distributed renewables Generation modeled –In-Service –Under Construction with expected ISD Wind resources –Capacity for summer peak based on historical – low contribution –Sensitivity cases for high wind periods Committed projects will be included as part of base case assumptions PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

9 9 Modeling Criteria for PNM Planning Area NERC/WECC Reliability Criteria (included with Study Plan) –Line loading criteria –Base Case and Post-contingency voltage criteria –Minimum voltage stability margin –Minimum/Maximum transient voltage and frequency Violations of performance criteria is basis for most system improvements. PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM

10 10 Final 10 Year Plan Facilities Facilities defined in this planning cycle for Native and Network Customer Load Growth and Point to Point Transmission Service Committed projects from other studies: –Previous Planning Cycle –Transmission associated with an approved IRP Studies performed pursuant to NM IRP rule. –Transmission for Generator Interconnections with notice to proceed Studies per FERC requirements –New Point-Point Requests with notice to proceed Studies per FERC requirements PNM Public Transmission Planning Meeting March 5, 2015 Albuquerque, NM
