  1. November 2011 Generation Resource Energy and Regulation Deployment Performance QMWG 12/2/2011

  2. Month-to-Month NON-IRR GREDP – Energy Deployments Resources below 85% threshold

  3. Month-to-Month NON-IRR GREDP – Regulation Deployments Resource below 85% threshold

  4. Month-to-Month IRR GREDP Resources below 95% threshold

  5. GREDP by Fuel Type

  6. GREDP Scenario Analysis * November performance of frequency excluded intervals was 90% (2803 passed/3103 failed).

  7. Manual HDL/LDL Override Summary QMWG 12/2/2011

  8. 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 17 total unique overrides in November • As compared to 18 in October and 13 in September

  9. Daily Summary Table

  10. Reasons for Manual HDL/LDL Overrides • An override is considered unique if that same Resource did not have an override within the last 10 minutes • 13 of the 17 overrides were the result of transmission outages • 2 different Contingencies/ Constraints were given as the reason for an override
