Units 1, 2 and 3 Docket Nos. STN 50-628/529/530 Class 1E, 126 Volt, D.C., Battery Load Profiles Enclosed are the Class 1E, 125 Volt, D.C., battery load profiles that you requested during the telephone conversation that was held between APS and members of your staff on January 06, 1998. Battery "A" has the highest equipment loading of each of the four Class 1E, 125 Volt, D.C., batteries. The performance test that is performed on each of the batteries has been superimposed on the duty cycle load profile for Battery "A" to demonstrate how the performance test bounds the duty cycle load profiles for all of the Class 1E, 125 Volt, D.C., batteries. The battery load profiles are being submitted as additional information for Reference 1.

Please contact Scott A. Bauer at (602) 393-5978 if you have any questions or require additional information.
