Three files attached 

Attached is the preliminary TTC/ATC calculations between CM/CSC Zones for On Peak Summer 2001.  Based upon these calcualtions it appears that the TTC based upon thermal limits (RateB) between CM/CSC Zones is:

South to North   3,700 - 3,800 MW 
West to North    1,100 - 1,200 MW 
West to South      500 -   600 MW 
North to South   1,100 - 2,300 MW 
North to West      800 -   850 MW 
South to West      300 -   350 MW 

We request SSWG review these calculations and provide any changes or updates no later than Friday May 4. 

Thanks Ken D.
