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

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.

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

7
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

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.

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
