  2. Antitrust Admonition ANTITRUST ADMONITION ERCOT strictly prohibits Market Participants and their employees who are participating in ERCOT activities from using their participation in ERCOT activities as a forum for engaging in practices or communications that violate the antitrust laws. The ERCOT Board has approved guidelines for members of ERCOT Committees, Subcommittees and Working Groups to be reviewed and followed by each Market Participant attending ERCOT meetings. If you have not received a copy of these Guidelines, copies are available at the Client Relations desk. Please remember your ongoing obligation to comply with all applicable laws, including the antitrust laws. DISCLAIMER All presentations and materials submitted by Market Participants or any other Entity to ERCOT staff for this meeting are received and posted with the acknowledgement that the information will be considered public in accordance with the ERCOT Websites Content Management Operating Procedure. http://nodal.ercot.com 2

  3. Full Market Trials Agenda • General Updates and Reminders • Cutover Updates by Functional Area • Cutover Activity Review • Question and Answers / General Discussion ERCOT asks that Market Participants log into the WebEx session using their company name and then their name. This will allow ERCOT to take roll-call offline http://nodal.ercot.com 3

  4. General Updates / Reminders http://nodal.ercot.com 4

  5. General Updates and Reminders • Network Model Load Dates • 11/24/2010 – Completed as scheduled - Last update prior to Go-Live • 12/15/2010 • The Saturday 4:30 PM Market Call on 11/27/2010 will be canceled • Note that the 10:30 AM call on the same day will take place • Daily calls will resume as scheduled on Sunday 11/28/2010 • REMINDER: Listener URLs • If there are any changes to your Listener URLs, submit those to ERCOT no later than today • Send changes to the nodalmarkettransition@ercot.com email address • REMINDER: Frequency of polling data from ERCOT systems • All MPs need to review the frequency of which they are downloading / programmatically accessing data from ERCOT systems • ERCOT Support Teams are finding several MPs that are accessing reports at an unreasonable frequency • For example, some Daily Reports (generated once in a 24-hour period) are being hit 150,000+ times / daily by some QSEs • This will assist ERCOT in gauging post Go-Live performance and sizing / scaling of systems going forward to support reasonable data access behavior • If there are questions on the frequency of a particular report, MPs can access the ERCOT Market Information List (EMIL), currently posted at: (Under Key Documents): http://nodal.ercot.com/readiness/reports/index.html • Revised ERCOT Business Practices Incorporating Guidance Related to Quick Start Generation Resource (QSGRs) • Revisions may be reviewed at http://www.ercot.com/mktrules/bpm/ http://nodal.ercot.com 5

  35. CMM - Credit • ERCOT continues to publish Credit Reports and ACLs daily, including non-business days • CMM is now the system of record for Zonal credit requirements • Total Potential Exposure (TPE) uses a) Zonal data and b) binding Nodal data. • No non-binding Nodal data (e.g. practice DAM runs) are included in the TPE calculations. Collateral included will be actual collateral held. • Some Zonal data will be included at a summary level only (e.g. AIL) or as adjustments (e.g. payment of Zonal invoices) • CRR invoice payments were received and posted Note: If you have not already, please validate your Credit Reports. Please send questions to markettrials@ercot.com with a cc: to ercotcredit@ercot.com . http://nodal.ercot.com 35

  36. CMM - Credit Shadow price caps approved for managing transmission congestion The board voted unanimously to approve shadow price caps and power balance penalties as recommended by the stakeholder committee process.  As required by nodal protocols, ERCOT staff developed a methodology for setting maximum shadow prices for network constraints and power balance penalties under nodal. The shadow price caps – a market tool for managing transmission congestion on the grid – were used during the nodal market trials and performed as expected, ERCOT staff said. ERCOT staff also noted that the shadow price methodology could allow prices to go above the current offer cap of $2,250 per megawatt-hour, as established by the PUC.  The PUC-established offer price cap is scheduled to go to $3,000 per MWh, approximately two months after the nodal market go-live. Excerpt from press release on the November 16th Board Meeting For full discussion see http://www.texasadmin.com/ercot.shtml http://nodal.ercot.com 36

  37. CMM - Credit • ERCOT systems require that all load requirements for an entity be met. In Nodal, load requirements can be met through a) Energy Trades • Must be confirmed b) the Day Ahead Market (DAM), c) Generation Resources that your QSE represents or through the d) Real Time (RT) market. Any load requirements not met through Energy Trade purchases, the DAM or your own Resources, will be met out of the RT market. • If an entity is a net buyer in the RT market in a period of high prices, exposure may escalate rapidly. • Entities that intend to not be active in the RT market should ensure that their load requirement is met elsewhere • Entities that intend to be net purchasers from the RT market, need to ensure that they have adequate liquidity to meet collateral requirements timely as exposure increases. http://nodal.ercot.com 37

  38. CMM - Credit http://nodal.ercot.com 38

  39. DAM - Credit • DAM credit parameters are set as they will be set for Go Live • DAM is currently using the 90th percentile for both the “uth” parameter and the RT DA spread (as approved by the BOD) • DAM historical values used for credit constraints • “e” factors are set to 1/0/1 • Will be effective through operating day - December 14th • Notices go out by two methods • E-mail to CP authorized rep and back up and CP Credit contact and back up is the primary communication tool • Written notices went out by regular mail • CPs desiring “favorable treatment” should complete and return the Request for Change in “e” Factor Treatment Form to ercotcredit@ercot.com http://nodal.ercot.com 39

  40. Go Live • CMM Go Live – Key Dates • Monday, November 29th - Send ACL for initial binding DAM (afternoon) (TPE excludes zonal invoice published on November 29th ) • Tuesday, November 30th - Initial binding DAM - “e” factors set at 1/0/1 - Credit Report include zonal invoice published on Nov 29th • Wednesday, December 1st – “Go Live” • CMM Go Live – General • See Appendix for detail of how exposure components will be addressed. • December 1-3 - “ramp up" for DALE - multiply the UDAA by a factor of five (5) each day until the first DAM invoice is published. • December 4-5 (Sat/Sun) - discount DALE by 25% since the first DALE is calculated on a weekend. DALE will be calculated at 100% beginning with Credit Reports posted Monday, December 6, 2010 and ACLs sent Monday evening for Tuesday, December 7, 2010. • See slide on expected impact of ACP on FMM in FCE calculation • If a Counter-Party believes that their Zonal ADTE is not representative of their anticipated Nodal RT activity, they can provide an estimate of anticipated RT activity and ERCOT will consider revising their ADTE. http://nodal.ercot.com 40
