  1. ICT 2011 Reliability Assessment and Construction Plan Evaluation Entergy Transmission SummitAugust 11, 2010SheratonNew Orleans, Louisiana

  2. Overview • Background • Scope • Draft Construction Plan • Results

  3. Background • Reliability Assessment is performed pursuant to Entergy’s Open Access Transmission Tariff (OATT) Attachment K. • Objectives: • Assess of the ability of the Entergy transmission system to perform according to the Planning Criteria. • Evaluate the Construction Plan’s ability to mitigate any performance deficiencies found. • Provide basis for development of the Base Plan.

  4. Background

  5. Background • Draft report was made available for stakeholder review and comment • Posted on Entergy’s OASIS July 1, 2010 • Presentation made at LTTIWG July 21, 2010 • Final report is posted on Entergy’s OASIS. • Detailed spreadsheets not included in report are posted on Entergy’s oasis • Background models, data, and other information is posted on Entergy’s oasis

  6. Entergy Planning Criteria • Planning Criteria • NERC Planning Standards • SERC Supplements • Entergy’s Local Planning Criteria • Entergy’s Business Practices (Planning Guidelines) • Posted on Entergy’s OASIS • NERC Planning Standards being revised

  7. Reliability Assessment Scope • Models (2009 Series Update 1) • Near-Term Period: Summer & Winter 2012 & 2016 • Longer-Term Period: Summer 2019 • Construction Plan Projects • Initial Scan: Approved Projects from 2010-12 Construction Plan (CP) • CP Evaluation: Approved and Proposed Projects from 2011-13 CP • System Intact Review – Category A • Contingency Scan – Category B • Breaker-to-Breaker analysis • ICT’s 100MW rule (Bus-to-Bus analysis)

  8. Reliability Assessment Scope (cont) • Sensitivities • Specific Load Pocket Criteria • Low Hydro Sensitivity
