  1. ATC Update W. Shannon Black Chair, WECC MIC MIS ATF TF

  2. Almost There • Passed • MOD-01 Umbrella 76.83% • MOD-08 Transmission Rel. Mar. 81.49% • MOD-29 Rated System Path 92.24% • MOD-30-1 Flowgates 1 74.26% • Pending • MOD-04 Cap. Ben. Margin 66.29% • MOD-30-2 Flowgates 2

  3. Let’s Make a Deal • MOD-30-1 and MOD-30-2 • Flowgates • Small concession was needed in Version 1 • Version 1 was released for vote to meet time line • Approved • Version 2 is in progress • Incorporates changes needed by WECC members • Version 2 forwarded to NERC for pre-ballot review / posting • Target to respond to comments on Jan. 9, 09. • WECC Team Recommendation • “YES” on MOD-30-2

  4. So Close! • MOD-04-1 Capacity Benefit Margin • Quorum: 79.26% • Approval: 66.29% • Small changes were made for the NE • Clarified language describing time windows • Should swing the vote • Forwarded to NERC Standards Committee • Request approval for Recirculation Ballot • WECC Recommendation • Next ballot – say “YES” • As drafted CBM is an “option” • “YES” protects that option

  5. Implementation • In excess of a year out • FERC actions to watch for • Needs to be approved • Will likely issue a NOPR to figure out • “How to implement” • “How to ensure the same numbers” • Get ahead of the game • Create a model template for the “Implementation Documents” et al • WestConnect? • MIC? • MIS?

  6. Questions?

  7. Frequency Response Reserves(FRR Update) W. Shannon Black Chair, WECC FRR Drafting Team

  8. What’s Happening? • Board (June 08) • Draft a “standard” • Standard Drafting Team (July 08) • Convened • Looked at the evidence (Sept. 08) • 11 Pro criterion / 0 Con criterion • Concluded a “standard” was not warranted based on the evidence • Concluded a “criterion” was warranted

  9. What Didn’t Change? • The FRR SDT agrees with the 2005 White Paper • Must ensure the future adequacy of FRR response. • Response must include • Primary response (0-30 seconds) after excursion • Secondary response (post 30 seconds) • Sustained for 15 minutes or until a return to 59.9 Hz - whichever comes first.

  10. Why Change Course? • 2005 Technical Team !!EXCELLENT JOB!! • Did an excellent job with the data they had • 2005 data was flawed • Laced with interpolation • Not everyone reported data • Wasn’t apples to apples • The data reported was not in synch • The 2005 Team took what they had and force fitted the data to match • Some reported data at 4 seconds, some 6 seconds • Some archived at 6 seconds, some 20 seconds • Data from dynamic schedules was often delayed obscuring the actual response

  11. Why Change Course? • 2005 data was more limited than today • 2002-2004 showed the frequency responsetrend was up! • BUT… • 2005 showed a downward trend! • 2006 the trend was up! • 2007 the trend was down! • 2008 the jury is out

  12. Why Change Course? • Get it right! • If the data was flawed • So to the answer • Penalties could be imposed for the wrong reasons • Test it • Draft the criterion • Test it against / with actual data • Morph into standard later if appropriate

  13. Calendar Highlights • 10/27/08 First draft / Post for 45 days • 11/14/08 Workshop 1 for Q and A • 12/11/08 Close Comments • 12/18/08 Answer Comments • 12/22/08 Post revised criterion for 30 days • 1/14/09 Workshop 2 for Q and A • 1/09-5/1/09 “Process” as needed • 6/09 OC votes • 7/09 Board votes

  14. Basic Features of Current Draft • Set the amount • Greater of • 2800 (or) • Two largest credible generator (G-2) outages at one generating plant • Communicate the amount • Annually to the BAs and RSGs • BA / RSG • Calculates it share of the overall • Function of generation AND load • Provides Primary and Secondary FRR response • Primary: 0-30 sec /Governors • Secondary: 30 sec to 15 minutes or until return to 59.9 Hz /AGC

  15. Basic Features • The criterion • Does not • Dictate “how” the provision is to be made • Does • Dictate the response must be provided • How that response will be measured • How often the measurements are shared
