2. Agenda Purpose of the PWG 2006 NCTPC process PWG efforts to date
Next steps
DRAFT

3. 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
DRAFT

4. NCTPC Process Flowchart
PWG evaluates reliability problems and current transmission upgrade plans
PWG develops and the OSC approves the reliability study scope
PWG coordinates the study analysis, identifies reliability problems, develops solutions with estimates of costs and schedules
Participants and TAG recommend scenarios and interfaces. The OSC selects interface and scenario studies for analysis
PWG coordinates the study analysis, identifies access problems, develops solutions with estimates of costs and schedules
Reliability Planning
Enhanced Transmission Access Planning
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 review the reliability study results
Participants’ resource planning processes
Participants and TAG review the enhanced access study results
TAG feedback on final draft Collaborative Plan
OSC approves final Collaborative Plan
PWG develops and the OSC approves the enhanced access study scope

8. PWG Efforts to Date First PWG meeting in September 2005
Sept – Dec: Compared reliability planning assumptions used by Duke and PEC
Oct – Jan: Developed scope for 2006 reliability study
DRAFT

9. PWG Efforts to Date Dec – Jan: Provided data for base case development
Load and resource forecasts
Dispatch order for resources
Coordinated interchange
Contingency and monitored line lists
DRAFT

10. PWG Efforts to Date Jan – Feb: Developed merged detailed base case
Feb – Mar: Developed potential alternative resource options for study
Mar – Apr: Performed base case and some generator maintenance reliability screenings
Apr: Reviewed initial reliability screenings
