  4. Goals Update

  5. Demand Response Survey Update • Team Lead needed to facilitate initiative • ERCOT has offered to administer a Demand Response Survey • DSWG to finalize questions for the survey at December meeting • Input from Market Participants will be confidential • On-line tool will be utilized to minimize data aggregation

  6. EILR Program Task Force Formed • At WMS last week they created the Emergency Interruptible Load Task Force (EIL TF) • Mark Bruce (FPL Energy) and Floyd Trefny (Reliant) were named as Chair and Vice-Chair • EILR TF is charged to draft PRRs/NPRRs to be presented at the December WMS meeting • The PRRs/NPRRs should provide ERCOT with a load interruption ancillary service to be deployed within 10 minutes of instruction as part of the EECP immediately prior to firm load shedding • The EIL TF is further charged to address the following specific issues: 1.    Qualifications & requirements 2.    Dispatch and recall 3.    Who gets paid, how they are paid, and who pays 4.    Effect on clearing price 5.    Compliance issues 6.    Coordination with other ancillary services 7.    Contract duration 8.   Procurement:  contract vs. auction, and Self-provision • First EIL TF meeting will be held Oct. 31 from 9:30a – 3:30p at the PUCT and will be a brainstorming session; RSVP to mark_j_bruce@fpl.com • Second EIL TF meeting will be held Nov. 8. from 9a – 4p at ERCOT Austin; “straw polling” on key issue areas to whittle down the options and make homework assignments to draft PRR/NPRRs • The WMS e-mail exploder will be used for EIL TF communications.  • Stakeholders from TAC and all the subcommittees are invited to participate in this process.  • The Task Force will not debate the need for an EIL ancillary service – it will design one.
