  4. PRR 404 – Energy Procured from ERCOT • PRR impact on ERCOT business and computer systems appears to be minimal although common use of RBS could impact the amount of BES available to ERCOT and impact operations • Effective upon ERCOT staffing requirements being filled

  5. PRR 404 – Energy Procured from ERCOT • Credit Committee proposed changes would review a QSE’s estimated net aggregate load and resource variance from schedule to determine RBS use • If net greater than 20%, then additional collateral would be required by ERCOT

  6. PRR 461 – Confidential Exceptions for Reliability Analysis • PRR addresses QSE data to be analyzed following a reliability event • Lists data to be made available not earlier than 10 days following such an event • No business, computer, or operational impacts; minor staffing impacts • Effective February 1, 2004

  7. PRR 467 – Elaboration on the Notice of Resettlement • PRR provides market with more information about resettlements, such as the reason for resettlements and affected dates • Minor business practice impact • Effective February 1, 2004
