  1. Reliability Assessment/Construction Plan Evaluation Overview and Assumptions 2007 Transmission SummitJuly 31, 2007New Orleans, Louisiana

  2. Reliability Assessment Assumptions • Reliability assessment used 2006 series models, April 2007 update. • Contingency scans were run on the 2008 Summer, 2008 Winter, 2010 Summer, 2012 Summer, 2012 Winter, and 2015 Summer • Monitored elements and contingencies • 69 kV and above for: EES, LAGN, LEPA, CNWY, WMUC, DERS • 115 kV and above for: CLEC, LAFA, DENL, SMEP, AEPW, EMDE, OKGE, SWPA • 230 kV and above for: SOCO, AMRN, AECI, TVA • Breaker-breaker contingencies simulated • Category C contingencies simulated for Entergy system • 2012 Summer model presented

  3. Count of Thermal Overloads Prior to Upgrades Category A

  4. Count of Thermal Overloads Prior to Upgrades Category B

  5. Count of Voltage Violations Prior to Upgrades Category A

  6. Count of Voltage Violations Prior to Upgrades Category B

  7. Construction Plan Evaluation • ICT evaluated Entergy’s draft Construction Plan Projects to determine: • What benefits were provided by the projects • If the projects addressed the reliability issues they were designed to address • If any changes to the projects are necessary • If the projects comply with the Planning Criteria • Construction Plan Projects were evaluated on the 2012 Summer model.
