  1. Market Flow Threshold Field Test NERC ORS Meeting • November 14th and 15th

  2. Introduction • Market flows are assigned an amount of relief by the IDC based on level of TLR, amount of curtailment requested and the priority/sub-priority of tags relative to the market flows. • On some flowgates, MISO and PJM are unable to consistentlyaccomplish their relief where they have verysmall impacts. • On some flowgates, the markets will either have no generation they can move or will require a large amount of redispatch for a small amount of relief. Reason For Change In Threshold

  3. Market Flow Threshold Field Test • The FERC, NERC ORS and NERC Standards Committee approved a field test to calculate relief requests based on a down to three percent market flow. This is for all entities that report market flows. • Conditions placed on field test: • 12 month test to be completed by 12/31/08 • Can start before 6/1/07 or after 9/1/07 • Must start no later than 12/31/07 • At least one market must be ready to start • NERC TLR SDT will monitor progress and make periodic reports to the NERC SC

  4. Implementation • On May 29th, the field test began. In addition to reporting market flows down to zero percent, PJM started reporting market flows to the IDC down to three percent. • On May 29th, the IDC began calculating PJM relief based on the down to three percent market flows. • SPP implemented on October 1st and MISO implemented on November 1st. • A summary of results was provided to the NERC ORS on September 19-20. This is a follow-up summary with an additional two months of data.

  5. Failure to Meet Relief Obligation • What does it mean to have a failure? • MISO, PJM and/or SPP did not meet its relief obligation. • Not all failures involve the use of three percent threshold (PJM participation started May 29, SPP participation started October 1, MISO participation started November 1) . • If one or more five minute window failed to meet the relief obligation, this was counted as a violation event. • In reality, you cannot expect an instantaneous change in market flows to meet relief obligations.

  6. Summary Results • IDC threshold reports analyzed for July, August, September and October. • The table below shows the number of TLR’s where an entity was unable to provide the IDC requested market flow relief.

  7. Result Observations/Issues • Because there was a delay in setting the market flow threshold by flowgate in the IDC, the use of 3% market flows for TLR curtailments was delayed (PJM-June 12, SPP-October 3, MISO-November 1). • The NERC/NAESB TLR SDT asked that the field test extend for a minimum of 12 months for each market participant. Based on a MISO start date of 11/1/07, the field test will continue through 10/31/08 • There were some reporting problems when the field test first started that prevented using the June reports and requiring manual processing of reports in the first 18 days in July. • Problems that continue to exist in the reports: • Gaps in the data where a TLR relief obligation existed but there is no market flow threshold report for this time interval.

  8. Result Observations/Issues Continued • Problems that continue to exist in the reports (continued): • The market flow threshold report sometimes shows a market did not meets its relief obligation for a time interval when there was no TLR and/or no relief obligation. • The market flow threshold report sometimes shows a markets did not have a relief obligation for a time interval when it did. • There appears to be some problems with the TLR events themselves where the markets are assigned a relief obligation based on firm market flows during TLR 3. Also see cases where there are large market flow relief obligations (100 MW or greater). • These and other issues will be discussed as the NERC ORS TF does a detailed review of the market flow threshold reports.

  9. Next Steps • Continue to collect data. • MISO, PJM and SPP are preparing reports that track not only the number of relief obligation failures but also the magnitude of the failures using plots from IDC (see slide 10). • Schedule an ORS Task Force call to analyze the data. ORS TF participants: Daryn Barker (E.ON.) Richard McCall (NCEMC) Jim Burlew (PJM) Lanny Nickell (SPP) Jim Busbin (SoCo) Greg Stone (Duke) Frank Koza (PJM) Mark Wilson (IESO) Tom Mallinger (MISO) David Zwergel (MISO) • NERC/NAESB TLR SDT will be invited to participate in the review. Are there other NERC ORS members interested in participating in the review?
