    Level of transparency for CRR ownership and market resultsERCOT is looking for TPTF guidance on whether protocols were correctly interpreted

    Three data items in particular:CRR ownership of record (all owned CRRs)Base loading CRRs (owned CRRs that are inputs into an auction)Auction results

    *

    1. CRR Ownership of RecordProtocol language:NP 7.5.5.2: ERCOT shall post monthly, by the fifth Business Day of the month, on the MIS Public Area CRR ownership of record for each source and sink pair and each flowgate: the identities of the CRR Account Holders, type of CRR held by that account holder, and total MWs held by that account holder.Current design:

    *

    2. Base loading CRRsProtocol language:NP 7.5.3.2(1): Not less than 20 days before each annual CRR Auction and not less than 10 days before each monthly CRR Auction, ERCOT shall post the following to the MIS Public Area:(a) For the CRR Auction, number and type (PTP Options or PTP Obligations) of CRRs previously awarded or allocated for each appropriate month, including the source and sink for each such CRR;(b) For the CRR Auction, number of MCFRIs that have been previously awarded or allocated for each appropriate month, including the flowgate for each such MCFRICurrent design:

    *

    3. Auction Results (Public)Protocol language:NP 7.5.3.1(2): Following each CRR Auction, ERCOT shall post to the MIS Public Area the following information for all outstanding CRRs following this auction:(a) PTP Options and PTP Options with Refund the source and sink , and total MWs; (b) PTP Obligations and PTP Obligations with Refund the source and sink and total MWs;(c) FGRs the identity of each directional flowgate, and the magnitude of positive flow (MW) on each directional network element represented by each flowgate;(d) The identities of the CRR Account Holders that were awarded or allocated CRRs in or before the CRR Auction;(e) The clearing prices for each strip of CRR blocks awarded in the CRR Auction; Current design (2 files allocation results and auction results):

    EDS3 Release 7 HandbookCRR EDS Handbook (EDS3 R7)V1.0 specifies multi-month auction trialIn reviewing readiness metrics, a strong desire was expressed for a full annual (24 month) CRR auction to be part of EDSCRR EDS Handbook has been updated (v1.04) to include testing of a full annual (24 month) CRR AuctionReserving request for TPTF approval of an updated version of the EDS Handbook until January, giving us time to finalize more details.

    EDS RemindersDecember 1, 2007Declare intent to participate in the EDS3-R7 email [email protected] with Primary Contact Name, Email and Telephone Number, as well as DUNS number of participating CRR AH.NOIEs submit PCRR Allocation Eligibility Form, along with proof of eligibility Proof of eligibility includes copy of long-term contract or, if own resource, the following: Board of Directors Resolutions, Construction Contracts, Certificates of Completion of Construction, Property Tax Statements, Insurance Policies Listing the Generation Resource or Audited Financial Statements.NOIEs wishing to be considered as NOIE Load Zones during EDS 3 R7 must submit the NOIE Load Zone Establishment formThis notification will not be considered binding for Nodal go-live, however the indication will allow ERCOT to appropriately form the network model for EDS activities.Wind Generation Resources (WGRs) within the boundaries McCamey Area wishing to receive MCFRIs during EDS must submit the Allocation Eligibility FormNOIEs and WGRs who submit the Allocation Eligibility Form must also submit the CRR AH application.

    *

    EDS RemindersJanuary 15, 2008 Market Participants wishing to participate in EDS3-R7 submit the CRR AH application. Market Participants wishing to participate must have registered for and completed ERCOT CRR Training. Note: only one representative from each participant organization is required to attend CRR Training.

    CRR Registration status20 entities (5 NOIEs) have emailed their intent to participate in EDS3-R7Of those, 8 entities (3 NOIEs) have completed CRR AH registration10 entities (3 NOIEs) have completed CRR AH registration but have not declared their intent to participate in EDS3-R7

    Notable absentees:CPS Energy(San Antonio), STEC, Brownsville, McCamey WGRs

    Registration status as of Monday, November 26 as known by the CRR team

    Business process clarification NPRR release mechanismERCOT proposes to remove the release mechanism language in the protocols as existing design provides a more elegant solution The following slides aim to explain the release mechanism compared to proposed implementation

    Feedback desired on appropriate percentage for base loading for Monthly Auction

    Assumptions made in this example (which may not exist in reality):The network capacity for 2010-2011 is the same for all monthsThe nominated MW is the same for all months The nominated MW amount is fully allocated; no monthly true-up allocation required
