  2. Task Force Subgroups • Subgroups were developed to work on issues to bring back to the larger task force. • Coordination of Net Schedule Interchange – Marilyn Franz, NV Energy • Questions: Do we check out every 15 minutes? Do we checkout the 15 minute intervals after each hour or the hourly integrated value? Is there possible checkout automation? • Group determined what the proposed intra-hour checkouts would look like.

  3. Proposed Checkouts

  4. Task Force Subgroups • Transmission Pre-emption Intra-hour – Kathee Downey, PacifiCorp • What is required for intra-hour schedules if the path becomes overscheduled? Are curtailments required every 15 minutes as path schedules change? What about reloads? • Recommendation will be that curtailments will occur prior to the top of the hour for all intervals in the hour and curtailments/reloads will occur within the hour as needed.

  5. Task Force Subgroups • Interaction with Market Structures and Seams Issues with CAISO – Jim Price, CAISO • Proposed Implementation of Renewable Integration Market Design Changes: Fall 2013 - Order 764 compliance filing Spring 2014 Dynamic Transfers: Add transmission reservation bid component & look-ahead forecast of VER availability Implement 15-minute market

  6. Task Force Subgroups • Fall 2014 Flexible ramping product in DA and RT markets Integrated DA market & residual unit commitment

  7. Existing Document Review • The task force reviewed NERC, WECC, and NAESB documentation to see if there are any impacts with 15 minute scheduling. • Some inconsistencies with timing tables in the NERC Standards with “on time” tags and the OATT 20 minute before the “scheduling interval”. Standards say 10 minutes before the ramp. • This is in the process of going through the NERC process to be updated.

  8. Integration of Schedules “Rounding Issue” • An issue with sub-hourly schedule rounding has been identified where total schedules could exceed total transmission reservations. While this is not expected to cause reliability issues intra-hour, concerns exist for possible manipulation of sub-hourly schedules and after-the-fact with compliance, billing, and settlement • A Survey was sent out to ask the task force members their opinions.

  9. Rounding Survey • Make no changes and round sub-hourly schedules according to existing rules. • Truncate any schedule that is less than an hour in duration when computing the MW value for the hour (e.g. 2.5MW would become 2 MW). • Require that sub-hourly schedules and sub-hourly schedule changes must be done in increments of 4MW to eliminate hourly rounding concerns

  10. Rounding Survey • Change to allow partial MW scheduling/integration • Round up the schedules in the 1st and 3rd quarter hours and round down the 2nd and 4th quarter hour schedules.

  11. Rounding Survey • The survey was distributed to the task force exploder on January 8, 2013 and a revision sent January 15, 2013. • Comment period is open until January 30, 2013. • Results will be discussed at the February 6, 2013 conference call.

  12. Order 764-A • On December 20, 2012, FERC released Order 764-A. • Deadline for compliance has been moved from September 11, 2013 to November 12, 2013. • Confirmed that intra-hour scheduling applies to ALL transmission customers that schedule under the OATT (network and PTP)

  13. Order 764-A • Confirmed that schedules for firm transmission service will continue to have curtailment priority over schedules for non-firm transmission service.

  14. Initial Guideline Proposals • 15-minute scheduling intervals will be xx:00-xx:15, xx:15-xx:30, xx:30-xx:45, and xx:45-xx:00.  • Intra-hour Requests for Interchange will allow use of firm and non-firm TSRs, including the use of (but not limited to) redirects, resales, and originals TSRs.   • Requests for Interchange submitted in Pre-schedule may be submitted with the 15-minute WECC schedule intervals. (customer discretion).

  15. Initial Guideline Proposals • Firm schedules would preempt non- firm schedules if submitted at least 20 minutes before the impacted scheduling interval. Non-firm schedules of a higher priority would preempt non-firm schedules of a lower priority if submitted at least 20 minutes before the impacted scheduling interval. • Requests for Interchange (e-Tags) must be submitted at least 20 minutes prior to the start of the scheduling interval to be considered ”On-Time” (not “Late”).

  16. Initial Guideline Proposals • A Request for Interchange that is Late (submitted with less than 20 minutes prior to the impacted scheduling interval’s start time) will be marked as Late by the Interchange Authority, but may be accepted at the discretion of the transmission provider. (Note: A Revision on the NERC INT Standard Timing Tables will be needed for this to occur). • If needed, curtailments will occur prior to the top of the hour for all intervals in the hour, and curtailments/reloads will occur within the hour as needed.

  17. Initial Guideline Proposals • At a minimum, ATC will continue to be calculated as Transmission Providers currently calculate today. • The top of the hour ramp would remain 20 minutes. Ramp duration for the 15-minute scheduling intervals would be a 10-minute straddle ramp. (Recommend: a re-evaluation of the ramp duration should be conducted 6 months after the implementation of 15-minute scheduling to ensure the ramp rates are appropriately set). • Balancing Area Checkouts will be as reflected in the slide above.

  18. Next Steps • Resolve the “rounding issue” in relation to integrated values of 15 minute schedules. • Initial recommendation will be that NSI accounting will remain as it stands today conforming with NAESB WEQ-004-19. • Based on survey result, may recommend a future change for WECC to consider. • A white paper will be developed outlining the recommendations of the task force and sent to the JGC by the March 31, 2013 deadline.

  19. Monthly Report and Updates • Minutes from Task Force meetings can be found on the Task Force site on WECC website.
