  26. Credit Update http://nodal.ercot.com 26

  27. Soft Start • CMM Soft Start – Key Dates • November 15th - Initial CMM reports generated and published • November 16th – First DAM run with credit constraints • November 18th – ERCOT is now using CMM as the system of record for Zonal credit requirements • CMM Soft Start - General • Total Potential Exposure (TPE) will use a) Zonal data and b) binding Nodal data. • No non-binding Nodal data (e.g. practice DAM runs) will be included in the soft start 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) • CPs participating in the DAM during the soft start are operating with a “real” ACL • Since the data used in the soft start TPE calculations is binding, ERCOT will use CMM exposures published beginning November 18th as the bases for binding Zonal collateral requirements as well as Nodal “soft start” • ERCOT will produce Credit Reports and ACLs on non-business days during soft start Note: Please validate your Credit Reports this week. Please send questions to markettrials@ercot.com with a cc: to ercotcredit@ercot.com . http://nodal.ercot.com 27

  28. Soft Start As CPs validate Credit Reports, please consider: • Highest ADTE • Reflects the highest ADTE of the last six (now seven) weeks - will continue to increase weekly to nine weeks • AIL • Zonal data is included at a summary level only • “Mismatched” volume is not displayed in the AIL report although imbalance dollars and imbalance volumes are correct (display difference only) • OUT – Adjusted for TCR revenues • Initially reflected the same adjustment as in most recent Zonal report • As of Thursday, reflects an estimate of TCR Revenues for November and 90% CRR Revenues for December based on load ratio share from October disbursement • OIA – Adjusted to reflect payments made on zonal invoices prior to due date (e.g. prepayments) • CRR invoices and inventory are included in the Credit Reports • CRR invoice payments are being posted as received • payments received before 12:00 noon will be included for the ACL available for the next day’s DAM (e.g. received by noon Monday will be reflected in Tuesday’s DAM ACL) • payments received after 12:00 noon will be included for the next day’s Credit Reports and the following day’s ACL (e.g. received after noon Monday will be reflected in Wednesday’s DAM ACL) http://nodal.ercot.com 28

  29. Soft Launch • Treasury • CRR invoice payments are being posted as received • CRR invoices are due today (Friday, November 19th) • If an invoice is due and a payment has not been received, ERCOT will send out an e-mail reminder to • CRRAH authorized rep and back up • CP authorized rep and back up • Credit contact and back up Note: Please be sure that ERCOT has updated contact information for your company – notices will be an automated process and will use the information in ERCOTs Registration system. http://nodal.ercot.com 29

  30. Soft Launch DAM • DAM credit parameters are set for Soft Start 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 on Tuesday) • DAM historical values used for credit constraints – see next slide • “e” factors were reset to 1/0/1 on Friday, November 5th • Will be effective through Soft Start and through operating day -December 14th • Notices went 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 30

  31. Historical prices used for credit exposure in DAM • Proxy prices to be used for purposes of calculating DAM credit exposure for go-live is covered in Protocol Section 4.4.10(8) • Implementation: • All nodal settlement points have been mapped to 2010 congestion management zones • Spreadsheet with the mapping is posted as item 11 at http://www.ercot.com/calendar/2010/11/20101102-NATF) • DAM historical settlement point prices • Import hourly average of zonal MCPEs over the last 30 days as a proxy • SCED historical settlement point prices • Import 110% of zonal MCPEs over the last 30 days as a proxy for Real-Time SPPs (this ensures the 10% Day-Ahead/Real-Time price difference called out in 4.4.10(8)(b)). • Ancillary Services historical prices • Import zonal MCPCs as a proxy for nodal MCPCs • As nodal data is created, the zonal data will roll off, so that 30 days after go-live, all prices used for credit exposure calculations will be nodal prices. • Imported zonal prices will be trued-up with any price corrections the next business day (timeline of zonal price correction posting). • Note that this process will be used during the soft start • On Nov 15, had 15 days of (zonal) data loaded, not full 30 days • By go-live, as a daily automated process runs to import the zonal data, there will be a full 30 days of historical zonal pricing data available http://nodal.ercot.com 31

  32. 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. Updates are in red. • 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 32
