  1. Manual HDL/LDL Override Summary QMWG 9/8/2011

  2. Daily Summary Graph • For this analysis, we captured unique HDL/LDL overrides • An override is considered unique if that same Resource did not have an override within the last 10 minutes • There were 3 total unique overrides in August • As compared to 105 in June and 20 in July • All 3 were SPS related

  3. Daily Summary Table

  4. August 2011 Generation Resource Energy and Regulation Deployment Performance QMWG 9/8/2011

  5. Month-to-Month NON-IRR GREDP – Energy Deployments Resources below 85% threshold - This is the first month that Resource 1 has failed.

  6. Month-to-Month NON-IRR GREDP – Regulation Deployments • Resource below 85% threshold • Resource 1 and 3 scored less than 85% for the first time; • Resource 2 scored less than 85% in June and July with higher deviations

  7. Month-to-Month IRR GREDP • Resources below 95% threshold • 38 failures • < 10 intervals – 18 IRRs • > 10 <= 100 intervals – 12 IRRs • > 100 intervals – 8 IRRs • Weighted Average – 82.55% • Average Deviation – 8.25 MWs

  8. IRR Total Intervals Scored – Month-to-Month

  9. August GREDP by Fuel Type

  10. August GREDP Scenario Analysis

  11. Performance Monitoring Expectations, August 1st • GREDP Expectations, August 1st • Nodal in its eighth month of stabilization • ERCOT has worked with QSE’s to improve performance since go-live • Improvements have been implemented • Curtailment flag (5/18) • Dynamic ramp rates (7/25) • ERCOT required to identify non-performers to the Texas RE and PUC
