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

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.
