Purpose of the PWG

  • Coordinates the development of the transmission studies to support the NCTPC
    • Establishes a base case model
    • Performs Resource Supply Option studies – focused on reliability
    • Performs Enhanced Access studies – focused on power supply economics
    • Develops cost and schedule estimates

Reliability Planning

PWG coordinates the study analysis, identifies reliability problems, develops solutions with estimates of costs and schedules

PWG evaluates reliability problems and current transmission upgrade plans

Participants and TAG review the reliability study results

PWG develops and the OSC approves the reliability study scope

OSC selects reliability and enhanced access solutions; checks for improved reliability through enhanced access solutions

OSC creates final draft Collaborative Plan

Feedback and Iterative Studies

Participants and TAG recommend scenarios and interfaces. The OSC selects interface and scenario studies for analysis

PWG develops and the OSC approves the enhanced access study scope

PWG coordinates the study analysis, identifies access problems, develops solutions with estimates of costs and schedules

Participants and TAG review the enhanced access study results

TAG feedback on final draft Collaborative Plan

OSC approves final Collaborative Plan

Enhanced Transmission Access Planning

Participants’ resource planning processes
