10-YEAR TRANSMISSION PLAN

PNM Open Transmission Planning Meeting November 2, 2017 Albuquerque, NM

4

10-YEAR TRANSMISSION PLAN

• OBJECTIVES OF STUDY EFFORT: • Support Data Base Development for PNM and

Regional Studies – 2019 (1-yr), 2022 (5-yr), 2027 (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


5

STUDY SCOPE

• Review transmission adequacy with retail and network customer updates to designated network resources and load.

• Determine if system mitigations are needed to serve expected obligations (load forecasts and expected firm transfers) during the 10 year planning horizon without violating WECC/NERC reliability standards.

• Develop operational mitigations or system improvements to maintain system reliability and associated cost estimates and schedule.

• Incorporate assessments of economic congestion to the extent a need is identified by PNM’s or other’s involvement in the WECC process for providing this type of assessment.


6

PROJECT DRIVERS

• Compliance with Reliability Standards • Provide Service to New Load Locations • Interconnection Projects • Recommendations for projects requiring

joint study or solutions
