Doug,
Trying to keep you up to speed.

This conference call < also included members of the TXU & Reliant TDSPs who have reviewed and < offerred input into the process. < < During the conference call we reached a consensus of what values to use for < the 2002 summer on-peak TTC ratings for the CSCs in the direction of base < flow (i.e. for West to North flow on the Graham to Parker CSC, for South to < North flow on the Temple to Sandow CSC, and for South to Houston flow on < the STP to Dow CSC). These TTC limits are shown in the PowerPoint < presentation attached below. Additionally, I have included a list of the < Boundary Generators and restated the CREs for each CSC by which CREs are < Closely Related Contingencies and which CREs are Closely Related Monitored < Elements. < < With the work that was done by this subgroup recently, we now have a high < degree of confidence that the CSC flows predicted by the Zonal Average < Weighted Shift Factors match very closely what is observed by power flow < software. Therefore, the doubt that we had earlier on this issue has been < resolved. < < One issue that was raised during today's conference call that needs the < attention of the WMS is, will TCRs be sold in both directions on the CSCs? < If so, then TTC limits in the opposite direction will need to be developed < as well. Ken Donohoo said that there has been some discussion on this < issue by different stakeholders this week and that clarity is needed. < < One last note on the CREs shown in the PowerPoint presentation, please < review it to determine if all changes that were discussed at Monday's CMWG < meeting are reflected. I know that the ones in the Austin area have been < removed; however, Jose Conto thinks that a couple were agreed upon to be < added at that meeting; however, he wasn't sure which ones they were. < Please let me know if you have any questions or comments. Thanks < < Shannon < < (See attached file: CMWG Subgroup Results For TTCs and CREs.ppt) - CMWG Subgroup Results For TTCs and CREs.ppt
