  1. TPIT and DSA/B Discrepancy

  2. Discrepancy with TPIT • TPIT/Case Discrepancy • 3732 (Cedar Bayou to Jordan Ckt 99): The DSB cases had the correct ratings, DSA cases were upgraded incorrectly. • 11TPIT0097 (Norwood Switch Autotransformer): Upgrade in rating of the autotransformer was missing. • 15TPIT0085 (Eagle Mountain - Saginaw 138 kV Line): There is mismatch between project description and the upgrade. Based on project name, Eagle Mountain - Saginaw section should be upgraded; which is not reflected in cases. Upgrades based on “Bus IDs” specified in TPIT do not reflect in cases either. • 14TPIT0052(Stanton East - Buffalo (SU) - Midland E 138 kV Line): Lines are partially upgraded. Stanton_E To SU-Trianlge To Buffalo section is inconsistent with SU-W_Stanton To SU-E_ Midland To Midlnd-E section. • More Information Needed in TPIT • Mason Road to Obrien Ckt. 25
