Today’s issues

• Transparency provided by CRR Reports– “Explanation of Market Submission / Retrieval Items” document

will be updated this week per comments received– Guidance requested about proposed report contents

• CRR EDS handbook– Content updated– Reminder / Status on registration

• Business process NPRR– Discuss alternate implementation of PCRR release mechanism

Level of transparency for CRR ownership and market results

• ERCOT is looking for TPTF guidance on whether protocols were correctly interpreted

• Three data items in particular:

1. CRR ownership of record (all owned CRRs)

2. “Base loading” CRRs (owned CRRs that are inputs into an auction)

3. Auction results

1. CRR Ownership of Record

• Protocol 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 CRRs

• Protocol 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 MCFRI

• Current 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 Handbook

• CRR EDS Handbook (EDS3 – R7)

– V1.0 specifies multi-month auction trial– In reviewing readiness metrics, a strong desire was expressed

for a full annual (24 month) CRR auction to be part of EDS– CRR EDS Handbook has been updated (v1.04) to include

testing of a full annual (24 month) CRR Auction– Reserving request for TPTF approval of an updated version of

the EDS Handbook until January, giving us time to finalize more details.

EDS Reminders

December 1, 2007– Declare 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 form

This 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 Form

– NOIEs and WGRs who submit the Allocation Eligibility Form must also submit the CRR AH application.

CRR Registration status

• 20 entities (5 NOIEs) have emailed their intent to participate in EDS3-R7– Of those, 8 entities (3 NOIEs) have completed CRR AH

registration• 10 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

Business process clarification NPRR – “release mechanism”

• ERCOT 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 months– The nominated MW is the same for all months – The nominated MW amount is fully allocated; no monthly true-up

allocation required
