  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.

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.

  20. Environment Report-Known Issues COMS New Known Issues • EOCPRCAP (Energy Offer Curve Price Cap) does not calculate when HSL=MW quantity and there are multiple quantities equal HSL. This only affects Real Time Ahead AIEC calculation under this very distinct data scenario • Multiple Extract issues (Next Slides) • Missing TWTG data for whole intervals (Due to missing SCADA, working on S&B integration logic to catch these instances) COMS Closed Issues • AIEC is calculating incorrectly when “Vertical Offer Curves” are submitted. Issue is seen when there are different offer prices for the same MW quantity on the curve • DAEOCPRCAP (Day Ahead Energy Offer Curve Price Cap) does not calculate when HSL=MW quantity and there are multiple quantities equal HSL. This only affects Day Ahead AIEC calculation under this very distinct data scenario Reminder: ERCOT will post known issues every Friday to the readiness center at: http://nodal.ercot.com/readiness/markettrials/coms/index.html http://nodal.ercot.com 20

Development team is currently working on an extract tuning fix to resolve the issue and this fix is scheduled to be implemented this weekend.

  23. Credit and Treasury Weekly Update July 2, 2010 http://nodal.ercot.com 23

  24. Week in Review • Posted Credit Reports • ACL and TPE Summary Reports were posted around 8:30 am • Remaining Credit Reports were posted around 9:30 am • Aggregate Incremental Liability (AIL) report was posted on June 25th. However, due to a weekend migration, CMM experienced a significant delay in data population of this report (added to the Known Issues list). As a result, this report was not posted this week. • A fix has been identified for this performance issue and is expected to be in place in the next few weeks • We expect that data will “catch up” over this weekend • We will begin posting the AIL report on Tuesday, July 6 with whatever data is available • Sent ACLs each business day http://nodal.ercot.com 24

  25. Week in Review • Credit exposures • Credit exposures should reflect market participant activity • There remain a few exceptions, which are listed on the Known Issues list • Extrapolation of high historical activity forward continue to impact exposure calculations for CPs with ongoing activity in Real Time • ERCOT did not override ACLs or adjust credit limits • Last week, ERCOT requested CPs to seek a “refund” of e-collateral to adjust it down consistent with exposure and begin managing in a more normal way • Have not received many requests for “refund” • ERCOT will make one last adjustment to reduce credit limits to 30% above TPE for entities that have not given instructions in the past week • Still see a significant amount of CP activity in the RT market http://nodal.ercot.com 25

  26. Volume by Counter-Party by Day http://nodal.ercot.com 26

  27. Next Week • ERCOT • Will post Aggregate Incremental Liability (AIL) report again on Tuesday, July 6th and will be posting this with the other Credit Reports from now on • Occasionally, some operating day’s real time estimates are missing due to delayed jobs. If this happens, the corresponding forward day’s estimates would also be missing (known issue). • Since ERCOT has not received many requests for “refund”, early next week, ERCOT will make one last adjustment to reduce credit limits to 30% above TPE for entities that have not given instructions in the past week • Reminders • ERCOT will send collateral calls if exposure exceeds collateral • If ERCOT sends a collateral call, the CP will likely not be able to bid in the DAM until additional e-collateral is received http://nodal.ercot.com 27

  28. Next week • Counter-Parties • Since ERCOT will no longer override ACLs and will make one final adjustment to bring credit limits to 30% over TPE, CPs should review Credit Reports, consider • a) their exposure and • b) upcoming DAM activity and send e-collateral as needed http://nodal.ercot.com 28
